The issue: So I've been having a curious problem with my 1080 Ti. It's quite vague to describe, but sometimes (on stock clocks) my GPU suddenly has a strong FPS drop (30-60% decrease). This happens completely unpredictably and it doesn't matter whether this happens during gaming or during a benchmark, the FPS will remain lowered by 30-50% regardless of what application I run until I reboot the system. . I've found a way to reliably reproduce it, so maybe we can get to the bottom of this. If I raise the max voltages on MSI afterburner (+100 mv) while using my stable overclock (+60 core, +500 mem) or even stock clocks, after 2-3 minutes of a Heaven benchmark the FPS will halve and the power draw will drop from around 280-310 watts to 180-230 watts. Once this happens, the GPU will behave like this in any application until I reboot. Now I don't think this has to do with instability of the overclocks. Going higher than +75 on the core clock crashes the application as can be expected, but at 0 to +60 mhz without overvolting it's completely stable except for that once in a week FPS and power drop. Temps shouldn't be the reason either as even with the +100 voltage and overclocks I rarely cross the 70°C threshold (max 84°C hotspot/VRAM temperature). Max 50% of the 16GB available RAM is usually used. VRAM usage is usually withing 2GB when the problem happens. Things I've tried: - Reinstall Nvidia drivers - Check for parked cores during the issue - Disable fast boot (both in bios and Windows) - Set power settings to high performance in Windows and Nvidia control panel - Unplug the USB controller (this was the culprit for someone else) - Check task manager for memory leaks or some CPU-intensive background process - Install Windows 11 (because why not) - Reapply thermal paste The weird thing is that this problem has been documented among varying Pascal GTX's the past 4 years and is not application-specific. It almost seems as if the whole GPU goes into a low power state that is only re-set by a full system reboot. It's not a memory leak, not a thermal issue, so what can it be? Maybe my 650W PSU isn't enough (but shouldn't it then just throttle or crash instead of going into this weird low power with normal clock speed state?). Any suggestions would be great! I'll provide whatever info or run whatever test you need!

Help me please my computer says its overvolting, i changed power supply and then took off the heat sink to clean it and now it says its overvolting and then shuts down please can someone help me,

Hello again and sorry for repost but I screwed up the voltage info in the last post and I tough it will confuse people up after they replyed. About a week ago I decided to make a 'mild' overclock to my 5930k at 4ghz, from 3.6 on my Asus x-99s motherboard. First tried with a voltage of 1.120 than 1.115v than 1.110v (which eventually crashed after about 8 hours of stressing). Than I raised the voltage to 1.115v again and it was stable after 48 hours of stress testing. Never crashed since than so for power consumption and efficiency I decided to use the Adaptive Mode instead of Manual Mode. So I launched BIOS and set it from Manual Mode to Adaptive Mode. I set the turbo vcore to 1.115 (which I found stable within manualmode) and the offset to Auto. When I booted back to windows I launched cpu-z andHWmotinor to check that eveeything saved corectly, I noticed something strange. The max voltage was 1.140 instead of 1.115 so I tough that maybe it's like this because I didn't set an offset. Back to bios I set the offset to 0.05 so if the cpu needs more power it will go from 1.115 to a maximum of 1.120 volts. Booted back to windows..maximum voltage was 1.140 again (**please note that I never used a stress test while under adaptive mode, just light photoshop renedering and gaming**) What I am doing wrong? Why the max voltage goes to 1.140 instead of 1.115 or 1.120 with offset ( as I set them in the BIOS)? I really need some.help on this because I feel like i'm doing something wrong and I can't figure out what Thanks!

Yesterday i got my new GPU a power-color rx-480 red devil. I've heard something about it having a messed up PCB compared to other brands. my problem is that im attempting to overclock it with msi afterburner but even after disabling all the limits in the settings the max over-volt i can do is 6mv it allows me to drag it much farther than i would ever push my card but when i click apply even if i drag it one more to seven it jumps back to 6. should i get a different overclock software or is there a setting i missed in msi afterburner?

Hey all.I've managed to get my 9900K stable @ 5200MHz. I've thrown everything at it like Cinebench R15 and R20, XTU, AIDA64, CPU-Z Bench, 3DMark, and hours of gameplay on various games without a single blue screen. My voltages and LLC are as follows...Adaptive ModeAdditional turbo vcore @ 1.150vOffset @ 0.210= 1.360 vcoreLLC6I'm using an ASUS Maximus XI Hero Z390 board.When I run lets say Cinebench with Core Temp running besides it to monitor vcore my vcore will overshoot to 1.50v!! Is this safe? Should I be concerned with this? Or are these readings inaccurate? Cheers guys!

So I want to change the voltage to my 4790k from my B43-G43 GAMING so I can increase my stability at higher frequencies. I've played with ring frequency (I understand I'm not hurting anything but I have no idea if I'm helping with stability). I'm pretty sure I'm on the wrong path with ring frequency though - just from what others have said. Here's the meat of the question: which voltage option(s) do I modify? CPU core voltage? Do I also increase ring voltage? Voltage offset? I'm not bluescreening or anything, just getting errors in WoW every now and again. I suspect a very small 8mV jump would probably do it but I'm not overly afraid to play around. The purpose of this is to get better FPS in WoW and other games, because I've learned that the CPU is probably my FPS bottleneck (gtx 970 btw). Though even if I'm incorrect about that, I am enjoying myself and want those dank high temps. Before overclocking, I could never get my CPU over 70C. Which just seems...like a waste.

Hi, I am having issues with an ASUS GTX 1080 Turbo that seems to be throwing out Voltage reliability PerfCap in GPU-Z, while also giving artifacts in high detail games, eg. CSGO. It also crashes when Witcher 3 loads in with high details with power limit being the issue. I've deduced that for some reason instead of throttling, the card crashes the game instead when it comes to Witcher 3. With CS:GO, increasing power limit and memory clock seems to help a bit, but still bugs out, drawing spikes and artifacts on loading screen. I have tried bios flashing it to stock from TechPowerUp's library to ensure the bios are clean, still has the same issue. Something I would like to try is possibly up'ing the Vram voltage in bios edit, as I think that is likely where the issue lies. If anyone has any ideas as to what to try, please let me know.

Hi Guys First my PC specs: CPU: Intel i5-4690 3.5GHz @ 4.0GHz #48C* RAM: 24GB DD3 @800MHz DRIVE 1: Samsung SSD QVO 1TB @950GB DRIVE 2: Corsair Force 3 SSD GPU: NVIDIA GeForce GTX 1660 SUPER Motherboard: ASUS Z97k (i think) And yeah i know that you cannot overclock a non k cpu but i am doing this with BCLK. But i ran into a problem. It just doesent boot at a BCLK speed over 109 (4.3 GHz) And at 104 it starts to get unstable (4.1GHz) So i saw at other peoples that they have like voltages over 1.6v. And i started thinking that the problem may be because of my voltage. Because my voltage is at 1.1v So i started to pit it up to 1.3 volts but it dident work. Should i go even higher and are there any risks or rules that i should follow to not fry my cpu? Because when this cpu gets destroyed i am not able to buy a new one. Btw. How can i effectively test the stability ? Thanks for help Jajaj

I'm having some seriously high voltage issues and I don't know what to do. At first I thought it was because of overclocking, but once I cleared CMOS and checked my BIOS to make sure all factory settings were back to normal, I go in and see it is at 1.32v still. And when I start Prime95 and it just jumps to 1.45 and stays there. Temperatures aren't too bad, as it stays highest is mid 70s. HELP. ANYONE.

I haven't been able to find a clear answer yet on this subject. If I overvolt my DRAM to 1.4v, can the Ryzen memory controller handle it (not degrade really fast)??

Hi, I just recently built a new rig, with a GTX 1070, I did some simple overclocking (+100 Core and +450 Memory). I am a big overclocker and I want the most out of my card, max temps always while stress stay under 68C, from what I have read online this means I have quite a bit of thermal headroom. However, when I try to overvolt it lets me apply it, but when I check, it shows no increase in core voltage. Also I can't get any higher core clocks with the voltage boost applied. Here is my exact card model: MSI GeForce GTX 1070 DirectX 12 GTX 1070 ARMOR 8G OC 8GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support ATX Video Card Thanks in advance everyone

I started overclocking my 280x just to test the water. I'm testing it with unigine valley. From the default 1000mhz core I would go up in 25mhz increments. At 1075mhz it ran fine for the 5-10 minutes tested. At 1100mhz unigine crashed fast so I thought it was time to overvolt, I unlocked the voltage but as soon as I unlocked it, everything was unstable causing unigine to crash and black squares everywhere.This lead me to believe that for some reason when you unlock the voltage it's not set to the default that it's at when it isn't unlocked since it gave me problems at 1075mhz which was stable when voltage was locked. How do I figure out where it should be?Another general overclocking question is, if crashing is a sign you should either back down the clock or overvolt, what are the signs that you gave too much voltage? That's the confusing part to me for both gpu and cpu overclocking.

You'll see my build in my sig At the moment I run my processor @4.2 GHz, and I've only notched the ratio up that little extra ontop of BIOS own overclock setting when running the Asus Optimized-profile inside BIOS - which clocks the processor cores to 4.1/4.1/4.0/4.0/4.0/4.0 GHz. What's interesting is that BIOS don't use any static voltage setting, but has an adaptive curve that changes the voltage by the needs of the CPU, so that it's lower when not needing much, but higher when the CPU has to work harder, to a maximum of 1175 mV. - Am I right in suggesting that this may reduce the wear and tear on the CPU, especially if I were to overvolt the CPU - as te higher voltage is only used during heavy load, and is backed down towards stock voltage while light work (surfing, office work etc). So in my case I would be at stock voltages maybe 70% of the time while working, but still be able to get that extra juice when gaming or running heavy applications when needed. Of course it's suggested on many places that it's much more safe to overvolt these days' high end consumer CPU's as long as you have the necessary cooling, and that you shouldn't be too anxious about it as long as you've done your research and takes overvolting phase in a calm tempo. But perhaps using this adaptive voltage setting reduces the wear and tear even further? Elsewhere there was a dude suggesting that this adaptive setting might be more harmful than setting a static overvoltage as the differencies in voltage and temperature caused by the curve, may wear and tear the material even more - however luckily I'm the son of a man with a PhD in physical chemistry active in the material branch for 25 years, and of course I asked him, and he stated that it takes much higher and much more frequent shifts in voltage and heat to become a problem - if for instance the tempearute would go from 40C -> 80-100C several times within an hour all day we would have a problem, but go between 40C -> 60-70 only a few times towards the evening there wouldn't be any problem. And isn't this what a CPU is built to handle? All those billions per second of voltage (and surely temperature also) shifts in the transistors as well as in the other parts in the CPU. - Is there any risk that the overclock setting gets unstable because of the curve - for instance that I've found the right voltage at 100% usage during a stresstest, but when the usage goes down to 90 (lighter stresstest) or 75% (heavy usage) the voltage according to the graph isn't optimal anymore and I get bluescreen? Or can I expect that if the voltage works at 100% I can expect the graph to still have a good voltage setting at the lower usages? Note that this curve is not linear, but seem to have been more custom made to match the different needs at different level - I've screenshoted the graph... note that this may be screenshoted inside AI Suite 3 but it only shows what BIOS already have setup. - In conclusion, would you recommend that I use a static voltage setting that is run all the time, or that I instead adjust the graph already active so it reaches higher as I increase the clock ratio? And why? Here are the pros and cons of adaptive vs static as far as I'm thinking right now (some will probably be wrong): PROS - Adaptive: You're at the stock voltage most of the times despite overvolting, meaning the overvolting has its impact reduced as it's not used all the time - Adaptive: Heat is decreased when CPU isn't used heavily as the voltage goes down, giving quieter performance from the PC as a whole - Static: More used and there are more references to different overclock/overvolt settings, so the results are easier to expect CONS - Adaptive: The settings get less fixed and more dynamic, giving more room for some error (at least if I edit the settings poorly) - Adaptive: IF I were wrong - may cause more stress to the material because of shifts in voltage and temperature (unlikely imo) - Static: Unnecessary voltage settings at times (for instance 1.3 V during light tasks, when it really doesn't need it)

Hi guys, This is my first post on the LTT forums and I'd like some help from anyone who has had experience with overclocking, particularly haswell. Long story short im a bit paranoid ATM. For a while now i've been trying to achieve 4.7 Ghz on my 4690k. I eventually managed to get it mostly stable with these: -Vcore: 1.34v(fixed) -Vrin/Input voltage: 1.85v -Cache/Ring 3.9 Ghz:1.175v fixed -All C states dissabled. Temps do not exceed 85-88 running Aida 64. For some reason my motherboards UEFI (Asrock Z97 Pro 4) doesnt handle blue screens very well and sometimes the temperature readout of the cpu locks up which can be fixed with a quick BIOS flash. No biggie UNFORTUNATELY while configuring everything again I managed to set the cache/ring voltage to 1.75v. The machine ran about 24h with this voltage at moderately high load. Now the CPU temp reads 57-60 at idle ish in the UEFI and remains unnafected in Windows(Real temp). Should I worry and is there any way of checking whether or not the chip has suffered any long term damage? Also how much is the average lifespan of a haswell chip and how much should i expect out of mine? Any input would be highly appreciated.

I understand that voltage affects temperature because more energy is being put into the processor, but how do different clocks affect a CPU's temperature at the same voltage? For instance, my 4690k can hold 4.2GHz at 1.17v. If I downclocked it to 3.5GHz but kept it at 1.17v, would it still experience the same temperature under the same load?

Some overclockers overvolt their CPU with raising the voltage offset (e.g.: +0.100V) and others simply type in a higher core voltage (e.g.: 1.100V). What ist the difference?

So I'm overclocking my 970 and got to +140 on the core offset before I got some crashing. When I try to stabilize with some mV, the max seems to stay at 1200. I've only tried using EVGA Precision because thats the one I like, would MSI afterburner yield differently or is the cap due to the card?

I plan on upgrading whenever the new r9 300 series comes out so I've been trying to overclock my 270x. The only problem is, I can't seem to unlock the voltage slider in msi after burner so I can only reach a stable core clock of 1090 and a memory clock of 1475 before artifacts and questionable behavior begins to appear, so if any of you in the community know what to do, it would be great if I could get some help.

I've been overclocking my GTX780 reference and noticed an odd trend when not under load. It seems as though Precision is reading substantially higher voltage than I've got enabled. It's currently set to 1.212v with a clock speed of 1200MHz and +520MHz on the memory. Real time monitoring with precision shows it reading upwards of 1.225v when idle. As soon as load is applied it runs at the designated 1.212v. I am not concerned with the heat, as I am water cooled with a full cover block. I am concerned that the overvolting could potentially damage the chip. Has anyone had any experience with this issue? I am overclocking using the latest version of EVGA PrecisionX Thanks in advance!

I want to overvolt my 780 classified by flashing an unlocked bios. But my problem is I can't seem to find an unlocked bios. Can anyone link me to a download?

Okay, so I'm sure there's a million other threads out there about overclocking your memory, but I could use some help here. I'm just starting to dabble in OCing and I need help getting my RAM past 1600 MHz. I have a motherboard that supports all the way up to 2800 MHz, so that won't be an issue. For reference, I'm aiming for something a little more modest i.e. 2400 MHz. I also need some help with suggested timings, voltage etc. I've seen Linus' videos regarding the pros/cons of RAM speed, so I'm not looking for a lecture about how 1600 MHz is more than enough speed; I'm looking for a guide to make my rig work just a little bit harder. Any tech gurus out there that know their way around RAM, I could use really use your help!

A card designed for max temp of 100°C and max of 116w. how much voltage can I throw at it before it becomes "dangerous"? (currently at 1.150v with max temps at 72°C) Is there a formula I should be using? WTF is ViD usage: MSI Afterburner shows it at 0% always; idle or full load. Why I ask: I have to flash bios to add more than 1.150v because it is locked. before I start I want to know how much room I have. I just want to go fast.

I have a GIGABYTE GTX 760 windforce edition and it seems the voltage limit on this 760 is capped at 1.212 and a power limit cap of 102%. Is there any way around this? I would really like to get a better overclock.

hey guys, i am picking up an r9 290 vapor-x (by sapphire) this summer... so, since i found nothing on sapphire's site or google i decided to make a new thread. will overclocking/overvolting an r9 290 vapor-x void its warranty? what about the tri-x card? ty for reading
