We recommend using memory that adheres to the JEDEC memory specification. 125mV to keep temps down and maximize battery life using ThrottleStop. is the voltage too high for 24/7 use? This thread is archived New comments cannot be posted and votes cannot be cast comments sorted by Best Top New Controversial Q&A jprovido • Additional comment . However, on my 3700x going above 1. 003, vccio 1. I have been trying to undervolt the cpu and currently have it set at "normal" core voltage and an offset of -110mV. Uncore is basically the northbridge. I know ideally you want it to be 300-400mhz below the core clock. 4,715. #3. 1000 in bios and drop nearly I am a Ryzen 5 3400G owner with a 3600MHz RAM kit that only hits around 3200MHz. 2 is max safe for this. For 1366, the Uncore voltage does a similar thing - so some boards call it VTT. (The default 1. In the test system we get Experienced overclockers will bump up uncore/ring ratio as a very last step, and here I was going into it with the setting at 47. If you can run at 6000MHz CL28 with tuned subtimings, then that's all SpeedStep - Intel - Feature that increases or decreases processor speed and voltage according to system load. Gigabyte z490 Vision: VCORE: 1. I have messed with timings, voltage (even tried 1. Uncore functions might include L3 cache, the on-die memory controller Edit: In case anyone ever finds this post in the future, I was able to lower my load Vcore voltage from 1. I managed to get -180mv off my i7-8750H which meant it would hold 3. When gaming, it heats up to the mid 50's - low 60's. Uncore includes cpu cache, soc and IF. When I try to do DOCP in BIOS it gets these timings: 4000Mhz - Frequency 2000 MHz, CAS: 18, RCD: 22, RP: 22, RAS: 42, RC: 64, FAW: 48, RRDS: 4, RRDL: 10, at 1. Also, uncore voltage will need a boost to make RAM stable. But if you override this in the bios Hi everyone, I'm trying to understand where to set SOC voltage in the BIOS for the taichi. I'm wondering about what's View community ranking In the Top 1% of largest communities on Reddit. Offset Prefix (0 for +, 1 for -): setup_var_vs 0x664 0x1 0x1. I just don't see that specific name in hwinfo and thought it could be renamed. first you dial in a stable cpu overclock, then see how far you can push the cache, then ram, then graphics. meodd8 • 7 yr. I’m on a 4690k 47 core 44 uncore. thats it for all the oc I9 9900k 4. So far so good, but in HWINFO I'm getting some max readouts of: CPU [0#] Intel Core i5-10600K: Core 0: 1. Such as those guys who spend weeks or even month (s) to tighten every parameter of sub-timings. Also I have C1E enabled, Cstates on auto and all the I’m debating on pushing my uncore down to 40 and push less voltages. 7GHz, meaning all cores can operate In my experience high uncore frequency is essential for highly tweaked memory. Don't neglect your cache ratio, and memory tuning. I would recommend that you stay under 1. Offset Prefix: setup_var_vs 0x865 0x1 0x1. These voltages affect the CPU's memory controller, so you'll want to run a memory test to make sure your RAM is still stable. 1v is usually the sweetspot. Opinions are Generally you should manually set the cache ratio and voltage to stock values in case the motherboard tries to increase it to match your core. Undervolting is pretty safe, yes - certainly far safer than the reverse. 14v, pch core 1. - Mainboard: ASUS ROS Strix z790-I. 38V - the uncore frequency and CPU frequency doesnt drop down idle. Try raising these as needed when increasing DRAM frequency. As it slows down the CPU clock speed, it lowers the voltage. 6, and the other ones at 4. llc5 cpu current 130%. The term vid has sort of been stolen to mean the bios voltage setting (requested voltage). 2 volts, plus or minus 5%. 3 or 4 So after going from a chip with a great IMC (9900KF) and being able to run my RAM at 4500mhz+/CL19 with an uncore of core speed -2. SoC doesn't dictate On EVGA boards this is how LLC is displayed in the bios: "-X% vdroop" would decrease the vdroop effectively letting the voltage drop (that corresponds to the current load) be smaller. - CPU: i9 13900k. The BIOS will adjust the CPU clock speed based on temperature. When it hits 93 degrees, it drops to 1. 325V, 32x mesh with 4000C15 RAM. Finally hardwareluxx is stating +350mv to +600mv for memory I succeeded to pass various tests (memtest, P95, RealBanch) only if I put Uncore voltage offset to +0. I actually had a game crash a couple of times after trying, and I adjusted it afterwards and found a voltage that lowered my temps a pretty good amount. Uncore can't go as high as core, so it's unlikely that you'll be able to match it with core. 8ghz at 1. "The uncore is a term used by Intel to describe the part of a microprocessor that is not the core. So the SoC/uncore applies to the Vega igpu, VDDCR doesn't. 512. im on an asus xi formula with a 9900k at 5. This is the guideline listed in the Kaby Lake OC guide. This feature allows motherboard vendors to block the undervolting using runtime tools like Intel XTU or ThrottleStop. The main reason why Intel added this feature is mostly marketing. 416V. So 1. - Cooler: NZXT Kraken z62 (in total 4x Noctua NF-A14 140mm fans, 2x bottom intake and 2x top outtake on the radiator) The CPU is idling around 50°C and running at 1. I've been dealing with bIos plenty for overclocking and I know the voltage is there,it's called ring voltage. 404V. 3. Originally the voltage identification table from the cpu itself would give the voltage to be used for every clock/power state. 7980XE @ 4. 37v(bios) extreme LLC 5GHz uncore. It can be used to stabilize RAM overclocks and a plugin of 1. Usually if you turn on The laptop has an 8750H, and I've applied an undervolt to both the core and cache of -. 35v), the SOC voltage as discussed which I assume is the onboard GPU (ive got the internal GPU on mine disabled in the View community ranking In the Top 1% of largest communities on Reddit. Currently at 5. Very little chance that 1. 100 mOhm Facebook Twitter Reddit Pinterest Tumblr WhatsApp Intel CPU and iGPU Voltage Offsets usually come in pairs. 520 making the Uncore voltage running 1. Plus the VCCIO/VCCSA may need to come up slightly. 23v . Some boards have 'minimum' and 'maximum' cache ratio. +250 mV for 4000 on a good CPU. Jun 5, 2020. Undervolting these may lower your uncore power. 900V and VCCIO to 1. 3V (BIOS set, this fixed OC gives me more MHz Memory Voltage Limitations for Intel Core X series. It's similar to SoC on AMD. Offset of Vcore is based on VID (ie, VID = 1V. I just put offset voltage -0. 1v to 1. Opinions are somewhat divided on how much effect it has on overall performance (if any). Before it "uncore" dropping to 800mhz, also did the CPU and I'am not sure if everythings allright? My cpu is i5 12400f and ram by xmp should be 3600 cl16 18 18 36 but locked vccsa voltage on my cpu didnt allow to set it so. Cinebench score was 2080pts CPU, 491pts single core and MP Ratio of 5. 1Ghz all core load. For example: if you set Core to minus 30mV, you should also set Uncore to minus 30mV. (I recommend HCI memtest to at least 1000% coverage. Use hwinfo for monitoring. I've also limited the Speed Shift to 92. 4 (nothing changed in bios settings besides the overclock numbers). Uncore frequency is the frequency of the non-core parts of the CPU, ie cache, memory controller, etc. 1ghz delidded, cache at 4500mhz, vcore adaptive is 1. While vcore is the actual voltage. 3v vcore Uncore ratio 46. Actually, on I'm worried since I had to setup my MSI X299 PRO m/b to 1. 100 / 1. 2V but Keep in mind that Uncore is the same as Ring Bus, and is sometimes known as 'cache ratio'. Generally speaking, the pairs should always be set to the same values. 23V is good, as long as you know for a fact that is your actual voltage. Just change that to 1/50 and LLC=high lowers the vcore to 1. 424v). Overclocking it gives something like 1/14 the returns of overclocking core (darkwizzie's OC guides have benchmarks). I think you have yourself confused. You need to increase Uncore Offset to run higher memory frequencies. Ram: Corsair vengeance 3200mhz XMP enabled Motherboard: MSI Specs: - Case: Sliger SM580. My new chip's (9900KS) IMC is much more limited and refuses to run RAM clocks beyond 3600mhz regardless of voltage. That’s why some models will only expose ‘Core’ in the BIOS Setup. •. It took me a week to figure out that 4. 3v is way above average for a 4790k. iirc, 1. The Plundervolt vulnerability (CVE-2019-11157) affected In other words, it's your memory controller. duxducis. The issue with Intel's -P series is that uncore power is extremely high (far worse than AMD's) and the fact that Golden Cove is less power efficient than Zen View community ranking In the Top 1% of largest communities on Reddit. ago. Anyway, the big problem on my board is that VCCSA and VCCIO seems to be in a sort of read-only state. Cache is part of uncore. 00 A IA Domain Loadline (AC/DC): 1. In this test my RAM running at 3500Mhz 16-18-18-36-2T with most efficient sub-timings for 24/7 Hynix AFR. Check that CPU is achieving its target clock speed. In our HWiNFO64 screenshot, you can see VCCIO and VCCSA do nothing for memory OC on X299. 750 and still no luck. 100v would be 1100mV. My temps range from 73-93 on my current voltages. 1V). Also I discovered on TwikTown Supermicro X299 Bios set Uncore offeset automatically to +0. We set this voltage to +250mv earlier, this should be enough for ~3400MHz DRAM frequency. But unfortunately the PC doesn't boot with above DOCP settings. This is set in the BIOS (refer to above guide for vdroop & vdrop). When I use the extreme profile (MSI center) it heats up to high 60's - low 70's. 8700k(Delidded) 5. You set Offset of +0. Often this is free, aka you can just raise it 500 mhz with no impact on power I've noticed that since my DDR oc @ 3500 cl15 16 16 34 , 1. Note that you usually get your voltage reading in monitoring programs from the SIO sensor, and it's pretty inaccurate as it's usually off by 100+mV, so if you see slightly higher numbers you should still be in the clear. 8 all-core, 1. I reached 1. Do not undervolt without comparing performance in cinebench - get your stock performance first and make sure undervolted performance does not degrade. Hey guys! I have an i5 13600k paired with a Gigabyte z690i aorus ultra lite DDR4 motherboard. Any idea But during my testing I made an interesting discovery, if the gap between the uncore and core ratio is too big the system becomes unstable and requires more Just recently build a new system with a 13900k and a ASUS z690-e Strix motherboard, and decided to enable the Ai Overclocking feature out of curiosity to see uncore disables power saving on a few things, forcing them to always run max voltage and frequency. 295v to 1. Hwinfo should show both. vcore spikes to 1. Raptor Lake is supposed to have 2MB L2 per Raptor Cove core and the same 2MB per 4core Gracemont cluster (E core, the same as Alder Lake, the E cores seemingly only get upgrades every second generation) 2. The PC boots with the default profile on 2133 Mhz and works fine but I want to get the RAM to 4000 Mhz or as close as I have the 13700K as well. 432v (vdroop to 1. So I decided to drop down to 45 ring ratio, and adjust Uncore voltage too high? I'm currently in the process of overclocking my uncore and I've noticed that my uncore voltage at 44 on my 5820k is at 1. 312 volts using Intel XTU reach cpu temp up to 82 degrees celsius under 100% load. 25v. 368V. 3Ghz Core Ratio and 1. This causes my computer to reboot during karhu's memtest I can still push 5ghz at lower voltage, but I have to down clock my uncore. The other place is just OC Tweaker > SOC/Uncore [Uncore/SA Overclocking] Voltage Offset: Supported Voltage Override: Not Supported Ratio Overclocking: Not Supported Fused Ratio Limit: N/A OC Ratio Limit: N/A Voltage Mode: Interpolative Voltage Offset: 0 mV IccMax: 11. Graphics voltage offset: -100mV GT Voltage Offset: setup_var_vs 0x86B 0x1 0x64 Vcore is the voltage the CPU will receive. 45) etc. ) bobbyqba2011 • 5 yr. Typically uncore is 3-5x below core, so where you're at right now is fine. I've been googling this for about 2 days now and at first I was fairly confident I had found it under OC tweaker > external voltages and [I forget rest of directory name] > CPU Options > CPU VDDCR_SOC. However, the CPU Silly-Weakness • 2 yr. Test system. If it goes above 90C, it will slow it down. I understand the DRAM controller / Infinity Fabric is coupled with the uncore frequency voltage. I’m sitting at +. What is certain is that it's completely pointless to set uncore frequency above core frequency. It is controlled by the 0x195 MSR and described in the latest Intel developer's manual (December 2022). 2v. 25v/1. If you can, that means your core can go higher. 170v (i believe these are all the same) both these voltages are in override mode. 0 GHz manually via the BIOS. 1GHz at 1. It's also known as ringbus frequency. 25MB L2 per Golden Cove (P Core) core and 2MB per 4core Gracemont (E core) cluster. IllMembership • 2 yr. 39v, then youve got you 2 DRAM voltages (1. Core Voltage Offset (HEX value for mV): setup_var_vs 0x662 0x1 0x7D. 285 +0. luls4lols Amd R9 5900x PBO | RTX 4070 Ti | 4x8Gb Rev-E@3733Mhz CL16 • 3 View community ranking In the Top 1% of largest communities on Reddit. Feeding it more voltage can help with things like Ram stability for the higher frequencies. once I had followed instructions there, undervolting was enabled in throttlestop. Uncore - Intel - Regulates the frequency of the that looks like normal speedstep behaviour of your cpu. Check that CPU is running at its target voltage. I have adaptive mode and dynamic modes on. Good to know! IMO running cache high is fine if it doesn’t take away from overclock. Karadjgne said: SoC/uncore is the voltage applied to components in the cpu other than the cores, things like the memory controller. 276v and still stay WHEA-free with 51x core, 48x cache by increasing VCCIO from 1. 07, ram at cl16 3466mhz 1. Obviously, 'cache voltage' is 'ring bus voltage' or 'uncore voltage'. 14v, sa 1. I recommend resetting everything to defaults in both BIOS and XTU, then uninstall XTU Recently I did an overclock on my 4690k. Someone else say that VCCSA and VCCIO do nothing for memory on X299, so the voltage that has to be changed is only the Uncore voltage (i thought that one was for the Mesh). 085v is 'stable', what that usually means is that the CPU is no longer boosting. Typical uncore overclock is 200-300Mhz behind core. Safe 24/7 Core and SoC voltage on all core loads and fixed OCs for Zen 3 Cezanne APUs? (5500, 5600G, 5700G, etc) Looking in making some OC to my new Ryzen 5 5500 (its a 5600G without iGPU). 35-1. i bet you were doing close to nothing, maybe a bit browsing while recording the voltage? if not under load, the cpu will Since Intel’s Coffee Lake generation, ‘Uncore’ automatically follows the ‘Core’ setting. 1V; Vcore becomes 1. 305v and then drops Memory is the final cache level in a sense, so much raising the ring ratio, the CPU becomes more efficient. The main risk with undervolting is system stability, ie system crashes but is otherwise fine. 360, but if the temps are around 73-85 it Solution. 2 GHz, I am stepping up the voltage to find a stable state. View community ranking In the Top 1% of largest communities on Reddit. Uncore voltage offset: -125mV Uncore Voltage Offset: setup_var_vs 0x863 0x1 0x7D. DDR: 1. 380V. DRAM Core - Uncore voltage again. Idles around 29-30 / gaming around 50-70, stress test around 80-85. Not to be confused with memory VTT. 7ghz uncore is unstable with 5ghz clock speed combo. I put those in order of priority, high to low. At the same time, we are also testing the upper limit of Intel Graphics (iGPU) Undervolting. During normal operations it runs between 38c to 47c. Undervolting i5 13600k Help . A mild bump to VCCIO helps with Mesh OC. Literally it was last Hope. In 2021, James survived what should have been a fatal electric shock while he was working as a high Best. That being the case, you may find a need for slightly more core voltage once the ring and memory are overclocked. Uncore also doesn’t draw lots of power either. 45V core voltage out of the box (no other changes were made in the BIOS, that should affect the Uncore voltage is another voltage all of its own, its not the memory controller as there is a separate option for that in the same list which you'll find is around 1. in my case, i had to install the OEM's undervolting software (Omen Gaming Hub -> Undervolt tab -> Install / Update). 7GHz at 1. Try +300mv for 3600MHz, +350mv for 3800MHz and +400mv for 4000MHz. 125V with no problems (with stock settings and Hyperthreading disabled). The sp of my 13900K is only 101 when paired with the ROG Z790-E, and it can run at -0. And if I start a prime95 torture test on the "smallest FFTs" my temps immidietly shoot up to 87 degrees and I'm puling 188 watts. 445V uncore offset for my current timings and frequency, but your mileage may vary. ahsba322 • 10 mo. Don't trust your motherboard with its own voltages when overclocking. Different programs have different names for it, but they all describe the same 4 settings. It definitely seems that uncore ratio needs to be spoken about more in the community. My first 9900X needed +450 mV, the second 9900X needed +300 mV, and my 10900X needed +250 mV. VID is the voltage identification tables that View community ranking In the Top 1% of largest communities on Reddit i9-12900K - Overclocking ring bus Testing different setups with Alder Lake and bench-marking and I came across this thread: The IMC (Integrated Memory Controller) voltage is determined by the uncore-offset, not by System Agent. Uncore doesn't really do too much for performance either, but it will significantly affect your voltage requirement. Anything over the specified voltage can damage the processor or significantly reduce the processor life span. For DDR4 memory: 1. Don't look VID. I have the same problem on my Dell G5, but I found that the issue goes away if I log in as for my overclocking settings cpu core ratio 43x dynamic turbo boost , eist , etc (whats enabled when dynamic is enabled) all enabled uncore ratio 42x now for the voltages in the bios i have set cpu core voltage 1. CPU SoC voltage is your uncore voltage. [deleted] • 4 yr. However, if Check that CPU is achieving its target clock speed. 4V voltage is pretty close to the default settings on my motherboard, 90/90 (or probably 110/110) AC/DC loadline. gigabyte didn't separate uncore Now, we will use the Intel® 9th Gen Core™ i9-9900K as our example in this guide, and by default all core Turbo of the Intel® 9th Gen Core™ i9-9900K is 4. Even though every guide and YouTube video said otherwise. Just set them to the same. I personally don't run benches as they serve no purpose for me because they don't reflect my normal usage. 23V under maximum load) You can do that manually on a Gigabyte board, but it requires some custom settings. 2GHz @ 1. Courtesy James family. Thanks for responding man. 35 V. I can change VCCSA to 0. The Intel P-series was a step back also ship with 28W power limits too, that side of things is perfectly normal. Once I have more time I will push it higher. VCCIO: 1. The memory doesn't seem to be the problem, so I'd have to guess it's the DRAM controller in the chip itself. Asus decided to name this voltage after two things it isn't (memory voltage and core voltage). • 1 6. Previously, I manually overclocked it up to 5. onedoesnotsimply9. I got all fast cores at 5. Compared to my Uncore frequency is the frequency of the non-core parts of the CPU, ie cache, memory controller, etc. 15v warned that it would disabled pcie gen4 to gen3. You're comparing it to Intel's more recent process which clocks like 500mhz higher. Already can do 4. 360, but if the With -70mV on CPU Core/Uncore on the other hand, the system seems to run stable for a while now. 3v for uncore voltage. 195v cpu ring/cache/uncore voltage 1.

Voltage offset of 13900K at stock. [1] The core contains the components of the processor involved in executing instructions, including the arithmetic logic unit, floating point unit, L1 and L2 cache. I’m debating on pushing my uncore down to 40 and push less voltages. Venia • 3 yr. VCCSA: 1. VDDCR SoC is the voltage of external graphics cards memory controllers etc. 456v for the UNCORE voltage (Auto voltage from BIOS was 1. very good temps with EVGA 280clc in push pull with Noctua fans. I can negate this limitation somewhat by dropping the uncore to core speed -10 (it can run at I recently overclocked my 10850k to 5. Next step is to try 49-50x while not touching Vcore and only VCCIO. 6GHz at 1. 36v xmp. 25v was just a test if increasing it did anything. 45V. Best would be to check in the BIOS, or using the GIGABYTE tool whether this value is reported as monitored. 72x if you are wondering. If not you’ll have to adjust in the AMD Overclocking section, enable SOC/Uncore OC mode and then you would adjust SoC voltage in mV. I was like, “what happens if I set uncore to 4. "+X% vdroop" on the other hand should make the vdroop stronger. Hence it allows to aim for higher voltages under load. Alder Lake (12900K) has 1. 320v) to be able to make my DDR4 as for my overclocking settings cpu core ratio 43x dynamic turbo boost , eist , etc (whats enabled when dynamic is enabled) all enabled uncore ratio 42x now for the voltages in Tuned Hynix M-die at 5600MHz offers roughly the same performance as tuned 6000MHz memory on AM5.
