But why is that ram using 1.65v at only 1600Mhz in that "guide"?, Most DDR3 memory i have OC'd don't even require 1.6v till 2133MHz+.

Also what is your Vcore while running IBT?

It fluctuates, but maxes out at 1.344 (using cpu-z). Core temp reports VID anywhere from 1.20 to 1.23. I will try those other settings and report back later tonight, thanks for the input.

1.344v is the same amount of voltage needed for my 3770k @ 4.6Ghz. Also when stress testing remember to check event viewer for WHEA 19 Errors. If your event viewer is loaded with crap and youd like it to be cleaner for your stress testing use this:
Warning: Spoiler! (Click to show)
@echo off
FOR /F "tokens=1,2*" %%V IN ('bcdedit') DO SET adminTest=%%V
IF (%adminTest%)==(Access) goto noAdmin
for /F "tokens=*" %%G in ('wevtutil.exe el') DO (call :do_clear "%%G")
echo.
echo goto theEnd
:do_clear
echo clearing %1
wevtutil.exe cl %1
goto :eof
:noAdmin
exit
Put that into notepad and save the file type as .bat with any name. (if running win8 run as admin)

Also remember that when getting a WHEA 19 error, can be a result of to much or to little Vcore. Always assume its to much first, dont give it more vcore than needed.

Side note, i was able to run my 3770k @ 4.5GHz Vcore- 1.280, PLL-1.5. So if it passes with 1.65v PLL lower it to 1.6v and see if stable. Any less i would not recommend regardless of what im using.

Also when testing your oc id recommend putting your ram to stock too if not already to rule out unstable ram OC.

Hey dudes,

Getting stuck at 1285 mhz / 1828 mhz for my clock (Haven't tried higher RAM, just trying to get my core up) and I'm running at voltages as high as 1.35 and 1.4v. Still can't get it higher. Just downloaded the new Classified controller. Any advice on getting this higher? What exactly does the PWM Freq do?

Thanks!

If it were me, i would 1rst set it to LN2, 2nd flash or reflash to "skyn3t-Classy-vBios-rev4", 3rd set the NVVDD to 1.3v and then set the gpu clock offset to +200 with EVGA precision. Raise the mem clock offset after you find a solid clock voltage combo, i wouldn't go over 1.35v on air, just my thoughts.

I'm running on water. And I'm running skynet rev2.but otherwise I'm doing what you've said. With new classy tool I'm stable at 1.3625 @1347mhz.

What should I be looking to do with this PWM setting?

This is what i could find on the PWM setting: http://forums.evga.com/tm.aspx?m=2110418

PWM freq: I think this is some complicated stuff about the frequency of the power going into the transistors or something. increasing it might make a overclock more stable apparently.

I commented about PWM frequency few pages back.

Thanks i found it biggrin.gif, have you yourself increased the PWM freq.? And is it safe to do so?

Thank you. I didn't see anything about safe ranges, though. Any advice on how to adjust it safely?

No I haven't touched it because I don't know why they left it at such a low frequency. AFAIK increasing it may make MOSFETs run a bit hotter because they will switch faster, so maybe they left it on low values because of bad VRM cooling. Increasing the frequency should decrease ripple, so you might achieve higher OC with the same voltage.

I have no knowledge beyond that, and electrical engineers like Sin0822 might have better idea what to do.
