post #821 of 3170
If you guys want I can fix the 1.50 and 1.60 BIOS for you and default the BCLK to 100.0 wink.gif

All you have to do is ask.

That review says zero vdroop for Gigabyte. Next board is going to be Gigabyte I guess. If I can I might buy a ivy bridge board. Else it will be haswell wink.gif

I have a trick for measuring vdroop

install throttlestop.
Use it to disable C1E and put it to the multiplier desired.
Now install cpuz
Read the idle voltage
Now load up prime95 blend up to 90% of RAM
If it's less use a higher LLC level
eg 3 to 2 or from 4 to 3
Do this until the difference is minimal.

I rather have LLC being little too low instead of being too much.

Level 3 should be fine for most of us I think

The Extreme4 has extreme vdroop issues above 1.35v.
I guess I will stick with 4.4ghz at 1.328v for my 2500k.

still prime95ing for the whole night. I put my cpu pll at 1.586v. Is this too low? Intel spec says 1.586v. I have no idea what this will do.

I found a thread saying Internal PLL Overvoltage WILL CAUSE DEGRADATION. I cant find the thread anymore, but he said it wont be noticeable. This was said by an intel enigeer overclocker.

could put in for example:
Known problems extreme 4:
- not detecting GFX, no video output.
possible fix: flash bios, reset cmos. reason unknown.
- bios 1.50-1.60 unstable
possible fix: flash bios to 1.70, bios unstable at 1.50 because of default blck 100.5
just thinking here tongue.gif probably people arent really looking forward to digging trough a 80 page thread to find a possible fix i there somewhere smile.gif
That is a good idea, i will try to do that this weekend.

Thank god! As a new owner of the Extreme4, it IS a pain to wade through all of these posts.

+1 for you!

I have that enabled, should i disable it?
post #826 of 3170
any overclocking/overvolting will cause degradation.. any electrical component running will probably eventually degrade(might be in 5 years, might be in 50 years but it will degrade eventually)

I' don't mind if it degrades in 5 years, I just don't wanna it degrades in just one month biggrin.gif, I already tested my cpu for OC at 102 degrees biggrin.gif LOL

you should be more worried about degradation because of high temperatures instead of the little bit the PLL overvoltage adds ^^ run realtemp all the time and check your maximum temperatures while doing things you do on your pc, it really shouldnt go past 85C to stay safe imo(so not prime/ibt temps, but game/folding/whatever you use your pc for tongue.gif)

no problem about that, max temperature 70 degres, because of this i'd like to overclock my cpu more, but i can't tested it under linx because it gets 102degrees already
post #830 of 3170
thats why i prefer testing with prime personally tongue.gif doesnt stress the temps as much but it does give you stability(granted it runs without whea errors aswell)
