@:
VTT=1.34
vCOre: 1.325
ICH CSI: 1.22
Freeze at 1m Linx. Temps under 80C

Same but with 1.3125 vcore: 124 BSOD.

I upped the DRAM to 1.65v and got the 0A BSOD, trying 1.41v VTT (I've heard this is ok, opinion?)
Edit: P95 small FTT gave me 3B.

Ok, now:
191xAuto (x20, x21 w/ Turbo)
1.36125v vcore
1.41v VTT
1.22v ICH CSI
1.82 CPU PLL
1.625v DRAM

OCCT (P95) Small FTT (i.e., "no RAM tested"): BSOD 124. Does this mean more vcore? Uhgg
Edit: with the same settings, I did Large FTT and got 1E. I'm going to try 1.375v, since with 1.36125v Large FTT (more real-world than Linx, which would probably get to 90C with these settings) I never got over 84C

124 means you have to adjust VTT. Although, the adjustment that needs to made could be either higher or lower. Since you've been constantly raising it, you should try to start lowering it and see what happens.

Based on some of the other error codes you've been experiencing, it looks like you'll still need more VCore. But, as mentioned, you'll need better cooling to accomplish that.

But does't it seem weird that I can run 200x19 at x VTT but not 191x21? I mean, the CPU is more stressed but the other stuff (QPI, Uncore, etc) are at a lower frequency, but require more voltage?
I'll try lowering it to 1.34v.

Yes, that's very strange. I can't figure out why that would be happening. confused.gif

Could it be that it actually requires more vCore? I've read that 124, for example, can be more/less vCore or VTT.

For me, personally, 124 has always been a VTT issue. But, like I said, you definitely need more VCore. So, with an increase in that, it's possible that you may see the 124 code go away.

Dude! You must be right on the edge of getting it! Thats when it seems the hardest!!
4GHz with all power saving is very doable!!! I know I did it, but I had help and this thread that I am posting will get you to your Goal and the extra $100 bucks...
Any problems just let me know..
Also clear all your settings like he say's and start from scrach, I bet you will be at 4Ghz in 6 hours or less!! Good Luck! and Happy Ocing!!!

Updatee biggrin.gif!
  • I reworked my case airflow, it was horrible, now @4GHz and 1.3625v (per BIOS) I get 85C in IBT max. Attached is a VERY CRUDE (as in "done by a three year old") airflow diagram.
  • H969, I followed that guide, it's great. I have determined that the issue I was (and am) having is related to the CPU: I can get up to 205 bclk w/ 1.34v VTT and DDR3 1640 w/ 1.6v and pass 2h Linx, but if I raise the CPU multi to 19 even, I need LOTS more vcore. This starts to happen at 3.6GHz, i.e.: for 3.6GHz, 1.2v (maybe even lower, I didn't test); for 3.8GHz 1.3v, for 4GHz ??. I'm retesting with 1.3625v, since I left it testing and it rebooted (I don't know how far in).
