just saying all I did was set the timings to 2666 cas 10 and switch to samsung 1.65v 2666 Ram preset

Use CPU-z and go to the memory tab.

Welp I am getting no luck with the DIGI+ changes. I upped the vcore to 1.42 and the VCCIN to 2.025v and still am getting that CLOCK_WATCHDOG_TIMEOUT BSOD about 5 minutes in the x264 testing. Sigh frown.gif

Why not try my advice?

What advice? the DIGI changes? I did do those.

Well I'm curious as to why I should do that now.

Because I am stable with 4.5Ghz @1.3v and since I've tried 4.6Ghz I've tried 1.350, 1.400 and 1.420 and with all those voltages I was getting a BSOD within 5 minutes of stress testing. So why start from the beginning with a lower voltage change if I'm only going to get the same result? Unless having a high Vcore can cause instability other than heat.

From what I've seen in my testing, a higher vcore can cause instability. You may have just hit the limit of your chip and 4.5 is just as good as it is going to get.

When you were increasing the vcore, were you also making adjustments to the VRIN? Keep in mind, that higher vcore levels will require higher input voltages....thumb.gif

Then stick with 4.5Ghz?
Btw there is no difference between 4.5 and 4.7Ghz.. Ok only in certain cpu bound game benchmarks like LostPlanet2 bench or Resident evil5 - fixed test, lower resolution. Not much though up to 5-8fps avg. at best..


Well I see yours is really power hungry, here are my examples just so you see how it scales, HT on.. Imo quite a big gap between 4.4 or 4.5ghz vs 4.7ghz

4.4GHz@ 1.145v
4.5GHz@ 1.176v
4.6GHz@ 1.228v
4.7GHz@ 1.278v


Edit:

I've lowered my OC 4.5Ghz @ 1.176v in the end, I dont see the point @ 4.7ghz by games anymore. I had it at 4.7ghz for ~ 2-3months and when I tested lower OCs 4.2-4.4Ghz is already fast enough in any game.. smile.gif

According to that screen shot you are running at DDR 3500 which I doubt would boot.
