UnOfficial Asus Rampage II Extreme Thread

I finally got a 5GHz validation on my system. The only way I could get it done was to boot into Windows @4.92GHz 234X21 then use SETFSB to up the BCLK to 238. I tested SuperPi a little more and was able to get it to complete @4.96GHz.

Congratulations m8

I just couldn't get my system to boot past 222 Bclk
Tried everything even the exact same bios template you posted earlier but no luck
There is just something missing I can't figure out. any thing over 4000MHz on the qpi and no post !!!

Must admit I'm starting to get a bit annoyed with the vdroop on this board. With load-line cali disabled I put 1.33vcore in bios, it shows as 1.3 at idle. Bit too high idle volt, since my clock is stable at 1.28 full load, although I can live with that. But during full load it drops even further down to 1.26... Thus making my system unstable. I turn up the bios volt quite a few steps to actually hit 1.28 during full load, but then my idle skyrockets.

So, I enable load-line instead and set the volt to 1.28ish, My idle stays at 1.26, but during full load my volt get boosted to in between 1.31 and 1.32. Which is not needed, thats just extra heat for an already hot CPU.
I set my volt to 1.26, full load jumps to 1.29-1.3. Good enough, but then my Idle volt drops too low, and my system crashes in between full load and idle. Sighs :P
Gonna try another bios than 1504, hopefully I find something less annoying :>

What temps r u getting? on what clock? what cooling r u using?

What temps r u getting? on what clock? what cooling r u using?

Thats on a noctuau12p and at the evening when the temps are falling. Midday I can easily push 85c on max load. 4.2ghz clock. HT on.
It's not that its impossible for me to run at 4.2ghz or higher, it's just annoying that I'll either have to settle with a high load vcore or a high Idle vcore.

Thanks blaxtr3m3.

I don’t know what the difference is between the two systems or settings for that matter. I found today that this setup really likes the pci @113 the best.

I don’t claim to have the answers to why your system doesn’t want to clock above 222Bclk but I’m willing to post any of the setting I used while testing my system. Of course as we all know, system may react differently even though the setting and components may be quite similar.

These are only suggestions and I bet you have tried all of the following in hopes of clearing the 222 Bclk wall but just in case. Have you tried relaxing the DDR3 timings and testing at a lower speed or tested with any other DDR3? Have you tried bypassing 222 Bclk and starting at a higher Bclk say 223-230 with the CPU voltage below 1.55v? This D0 doesn’t like the voltage above 1.55v until it’s running above 230 Bclk.

Some chips just won't do BCLK over 222MHz/QPI over 4GHz. It's a simple as that. I'm not saying that your chip is or isn't one of those, but rather just stating a fact.
