UnOfficial Asus Rampage II Extreme Thread

[connector]

I'm not sure I understand your question. You stated before that your issue was that you could not POST at over 160 BCLK. From what you just said it sounds like you can POST over 160 BCLK but only with CPU speeds of 4-4.2 GHz. I just need a clear description of what is going on here.

Ok, i did the test with your values:

"Multiplier: 21
BCLK: 165
Uncore: 3300 MHz
QPI Data Link Rate: 5955 MT/s
Ram: DDR3-1650 MHz
Ram timings: 9-9-9-24 rest on auto

Vcore: 1.35v
QPI/DRAM (Vtt): 1.30v
Dram: 1.65v"

and i can't post... I don't understand why, if i go over 160 in BCLK with a QPI Frequency fixed to "SLOW MODE" i can't post...

For clarify, I thought I had a problem with the QPI Frequency wich seemed not to change the multiplier (despite i've changed in BIOS)... but thanks to your help, i discovered that the BCLK over 160s may be the "issue"... i don't understand why i can't post with 200 BCLK.

If i use 160/156 x 27 (regardless my QPI Frequency), i can reach 4.200Mhz or more speed without problems (or using multiplier 133 x 32 for example). All my system is stable with those values, good gaming, temperatures below 80º on hottest core with PRIME 95, etc...

So i have 3 questions to be resolved...

1) My "dilemma" is to use 200 or 160 in BCLK...
2) My "question" is why i can't set 200 in my BCLK if i don't change my QPI Frequency to "SLOW MODE"...
3) and my "problem", is there something damaged in my hardware?, should i worry? or if i can reach 4.200Mhz with 150-160 BCLK i have enough power to move my 5970s

Sorry for make a post so long, sincerely, i appreciate your help because i'm tired of looking for answers about...

thank you again for your help, awesome thread and great forum
