So it's your basic story i7 920 with high end air cooling (Scythe Mugen 2).

Here's what I tried.

CPU multi @ 15x
BCLK @ 220
QPI @ 36 (also tried slow)
RAM @ 6x (ram is GSKill F3 1333mhz)
Uncore @ 13x
cpu vcore @ 1.35
QPI VTT @ 1.5
ram VTT @ 1.6

This results in a no post.


4ghz works though:
CPU multi @ 20x
BCLK @ 200
QPI @ 36
RAM @ 6x (ram is GSKill F3 1333mhz)
Uncore @ 13x
cpu vcore @ 1.35
QPI VTT @ 1.5
ram VTT @ 1.6

Tips and tricks?
 
I have to raise my QPI vtt to 1.520 (next step up) on my UD5. Otherwise, I admit I haven't been to 4.0 yet, just got stable @ 3.8 and have different RAM. Mine specs for 1.650, which again isn't in bios so I run 1.660. Nor have I yet run my bclk over 200. I think I'll go do that now (19x210 or something).
 
yeah looks like it's my QPI
when it shows in bios at 7.2 we are all goo at ~7.4 it locks up detecting the driver >7.4 is a no boot.
 
2nd hand info from xtremesystems - there's a hard mod/resistor change which enables PCIE clock to be run up over 103, which then bypasses a barrier of 222 bclk. This is for the UD4, UD5, Extreme mobos. On the UD3's, they say rev 1.0 has no fix and rev 1.6 needs no fix, ie, can surpass 222 as is no mods.

Guys are reporting much better bclk with PCIE upped but the numbers vary wildly, some guys say 105, next guy says 114, next guy says 129, and so forth. They say it won't kill a video card, and that SATA never changes from 100, but the onboard LAN can quit working. YMMV etc, just tryna help with info I read earlier tonight.

That's intersting.

My board is a rev 1.6. I may try bumping the PCI to 105 and see what happens.
