try this. open a command prompt with administrative rights, type in "sfc /scannow". this will check the file system integrity. If VCore wont fix it, you might have some damage to the OS, and sfc should be able to sniff if out. if that comes back clean, try checking your HDD for errors, and then run a MEMtest.

Anyways it seems to be running smooth far, I turned the fans down to 800RPM when I went to bed and max temp was 71c after running P95 for almost 15 hours, when I run the fans at full speed the temp is in the 50's so I'm definitely confident in running this 24/7.

Thanks for the help Lucky 23! smile.gif

In your case, you are going for a higher overclock, so unless you have a real high idle vcore, negative offset is just likely to cause hard to diagnose idle stability issues. As for LLC, moving to LLC2 or LLC1 without touching voltages will increase your vcore, but might be just the bump you need.

Alright, I have progress!

Got the CPU stable at 4.7Ghz:
Voltage offset: +0.01v
Turbo voltage: +0.91v
LLC - Level 2
PLL - Enabled
PLL Voltage - 1.75V (not sure why i even bothered with this)

CPU-Z & HWMonitor Vcore fluctuates between 1.376v and 4.0v (staying bellow 1.392 ~75% of the time) at full load. How does that seem to everyone?

Prime95 Blend stable for 10+ hours (see screenshot). Prime95 Custom with 1344 & 1792 FFT's also ran for ~1hour.



Based on monitoring Max Temp's peaked at 75C on a few cores overnight, although the highest i saw temperatures get to while running BF4 for 3+ hours was 63C. I am pretty comfortable with that personally.

What i noticed was that if i put the LLC to Level 1, even with almost zero offset and/or turbo voltage my VCORE shoots up above 4.0V, so i just settled at level 2 and a bigger Turbo Voltage, this way my CPU will run nice and low for 90% of the time and only spike up to higher volts when i am doing something intensive! Its strange that there is such huge vdroop between LLC level 1 and level 2.

Anyway, not that i am complaining i suppose. Any suggestions/tips to continue the overclock are appreciated but i probably will stick with 4.7GHz unless i can got up further without raising voltage.
post #7435 of 9531
I am currently overclocking the same CPU on the same board. The settings that seem to be stable are

x47
offset +0.005v
turbo +0.148v
LLC level 2
PLL enabled @ 1.709v

This gives me a max vcore of 1.392v / avg 1.363v. Temps are max 58°C / avg 50°C (under water). So far p95 fft 8k-1792k has only been running for a little more than 1.5h so this might change.
Just to give you an idea of what someone else's results are. Maybe someone else with more experience can chime in here if those are good / bad results.

Thats interesting....my Max VCORE is only 0.008v higher than yours, but the Turbo Voltage i need to achieve that is WAY higher...~0.75v to be exact. Wonder if my LLC level 2 is not compensating nearly enough....

Thats really strange, I will try and figure out my avg vcore to compare. Is your avg based on a large period of time? I am assuming thats the average under load?

I am running on air, but very comfortable since idle temps are 24C-32C and they top out under 65C during everyday use (gaming, etc.)

Curious, what kind of 3DMark 11 scores and/or BF4 framerate do you get with that monster of R9 290x? hehe

I am running pretty steady on fully maxed ultra settings BF4, generally above 60fps unless in a massive 64 player server when it dips into 50's. Flashing my videocard to R9 280x and overclocking from there has made a HUGE difference!

You guys have different VID from intel. Your chips are almost twins, but despite that, they were binned for different VID tables. Possibly different factories, or different runs at the same factory, or maybe as simple as two different techs testing them. This is just another example as to why VID is really only usefull as a reference point to apply an offset.

Reinstalled the OS and all the proper drivers but still getting the same error on x37 with offset core of +0.035 and turbo of +0.050. Something isn't right

Thats all fine and good, have you run sfc /scannow on the new install? Have you run a memtest? checked the HDD for errors?

Scan came back fine, Memtested all of the DIMMs and they passed, OS SSD is perfectly fine. Got it up to 4.3GHz with fixed voltage of 1.200v Vcore and +0.070 Turbo, looked like the DRAM Voltage was on Auto and was screwing up my OC but now I've hit a wall at 4.4GHz where nothing seems to work. Still getting the WHEA error at x44 and voltage increases seem to do nothing. All settings are exactly as the guide suggests for Fixed Mode OCing.
