Trying to OC, but Already at 100c ~10900k

[Mackerel Ice Cream]

I haven't even started overclocking yet. Today, I finished work and was all excited to start OCing, but I have to do it correctly. I gotta start off with the baseline. No overclocking at all. Clicked start within Prime95 with small FFTs, and bam! within five seconds I am already hitting mid 90c to high 90c with a single core hitting 99c. WTF! I wasn't prepared to handle this huge let down mentally. I reseated my AIO and the thermal paste looks like a textbook example of perfectly applied thermal paste. I feel like I could pick up my motherboard by the base of the AIO. It's screwed in correctly and tight. The AIO fans are spinning up during the Prime95 tests and it's connected to the MB. I don't know what to do. Is it possible to be this unlucky?

I am using my old case Xigmatek Elysium until I buy a new one.

what clock and voltage is the cpu running at during p95 small fft?

Can you take a photo of your system?

Is the mobo auto OCing via multi core enhancement or something like that? Use HWinfo64 to see what speeds its actually running at when you put an all core load on it. It shouldn't get that hot in prime at stock, but just don't use prime95, its such a huge power virus it just isn't real world at all. Use Asus Real Bench: https://rog.asus.com/rog-pro/realbench-v2-leaderboard/

 

See what temps in that are, and what speeds its actually running at while stressing all cores.

I'll double check later on. I think it was 50x and low 1.3V, but I'll confirm this later on. The voltage looked good though yesterday.

It's similar to this. The case is humongous.  I'll take a photo later on.

Enchanted Mult-Core Performance was enabled by default, but I was going to keep it enabled for overclocking anyway. If you have more questions about the default bio settings, ask away. I wrote it all down. I'll try Real Bench later on today. Thanks for the replies everyone.

There you go. This is your issue.

 

Multicore Enhancement is the Auto OC feature on the motherboard. While this will give you extra performance, the OC feature is not intelligent at all and it only throws extra voltage on the CPU to make it stable even if it could run at a much lower voltage.

Combine that with the AVX load in the P95 stress test (it is called a power virus for a reason) it will make the CPU run insanely hot. 

 

So basicaly there is nothing wrong with your CPU or cooler. Go to BIOS and disable MCE and do your own OC, it will give you likely higher clocks at lower temperatures. And by the way, you can always lower the max clock with the AVX offset in the BIOS so that the CPU doesent run insanely hot when using AVX, the CPU will automaticaly downclock in those workloads... it should have no effect at your gaming performance.

Would you recommend that I not use a guide like this? This one. I have read a lot lately in regards to 10900k overclocking, but would you recommend another source or guide? Please excuse the basic question. I have heard and read from different sources that enabling Multi-Core Performance should be enabled for ocing 10900k because of stability issues without it.  I haven't overclock in a while, but this was my plan.

 

 

~XMP set [Profile 1]

~MCE enabled ~Disable this then?

*Windows>Run Baseline w/ Prime95 small TFFs ~Or switch over to Real Bench or Cinebench?

 

~CPU Core Ratio: Sync All Cores ~Is all core sync enabled by default on my gigabytes? I'm not finding it.

~CPU Core Ratio: 49

~AVX Instruction Core Ration Negative Offset: Zero ~Is zero acceptable or should there be an actually guide?

~CPU LLC: Leve 4 

~CPU Vcore: 1.3

*Windows > Prime95, Real Benchm, or Cinebench

~Save the profile

 

~CPU Core Ratio: 50

Crash? CPU Vcore: 1.35v

*Windows > Prime95, Real Benchm, or Cinebench

 

~CPU Core Ratio: 51

~CPU Vcore: 1.4V

~Crash? CPU Vcore: 1.41v

~Crash again? CPU Vcore: 1.42V

5.1GHz worked? 1h Prime95, Real Benchm, or Cinebench

 

Try for 5.2Ghz? or maybe even 5.3GHz with an AIO?

 

Rule of thumbs: Never go over 90c, Never go over 1.5v vCore

 

The only thing is isn't 1.41v or 1.42 or more a little too high for the Vcore right? I've heard conflicting reports on the Vcore limits with 10th Intel processors. Thanks for reading all of that.

Disable MCE, you don't want that at all when OCing.

 

Sync all cores should be enabled by default if I'm not wrong, basicaly it should make all the cores boost to the same frequency instead of only one core.

 

Core ratio = multiplier * base clock (so if base clock is 100MHz by default and you put in 49 it should result in 4.9GHz)

 

AVX Instruction offset is what you should tweak. If you want CPU to run at 5.3GHz for example, it will be very difficult to make it work with AVX without the CPU overheating so if you set Core Ratio to 53 you will get 5.3GHz but if you then set AVX offset 4 it will only clock up to 4.9GHz when AVX is being used instead of 5.3GHz.

 

LLC = there are many explanations for what this is online, very important for OCing, definitely read more about it.

VCore, generaly try to keep it as low as possible, I wouldn't recommend anything more than 1.3V for a beginner like you before you understant how LLC has an impact on core voltage.

I was extremely worried about going over 1.3V with my previous overclock. I was surprised to see recommending it with the 10900k. I'll look into LLC and Vcore and their relationship. How would you advice handling Ring Ratio vs or with CPU Clock Ratio? I need to read more into Ring Ratio. Thank you for the detailed response. I appreciate it. I'll disable MCE and report back.

Buildzoid has a 10700K overclocking video on a Gigabyte board if you have a spare 2 hours to watch it 

 

 

And regarding AVX:

Haha! Thanks for the link. What a commitment, but I bet it will be good. Thank you

ring is related to the cahce, just leave it be until you get everything else stable

I ran RealBench at stock and it was better than Prime95. 15 minutes with RealBench. HWinfo’s Max was 88c 1.356v. I’m hoping to start overclocking now. Would you recommend doing the following? My goal obviously is to try to get a stable 24/7 without degrading the CPU.

 

XMP - Profile 1

MCP - off

CPU Core Ratio - 49x

CPU VCore - 1.25V ~Should I start higher or lower?

 

Increase Core Ratio until Windows starts crashing.

Then increase LLC to try and stabilize Windows.

Next increase Core Ratio and VCore until I hit my max or crashes

 

Max:

Temperature 95c ~Should I go for low 90c instead?

VCore 1.3V

LLC High ~Is high a good max for me for now?

I’m not sure where AVX offset comes into play. I know it needs to be low. But how low? 1 to 2? 1 to 5? I’ve always read it should be set to zero.  LLC applies more voltage during CPU load increases which fixes vDroop/vDrop. ~~Multiple levels to LLC, 25%, 50%, 75%, 100%. 50% to 75% LLC seems to be the best, 100% LLC is probably out of my reach for now. Overvolting is very possible with LLC. That’s why I want to fine tune LLC before getting to my max with VCore.
