Live MB OC Report :: ASUS Rampage Extreme

[Mezzro]

Mezzro, you mention FSB wall, then you say it happens only after clocking 4.2Ghz. What sort of figures were you expecting from this motherboard? Curious as I can't seem to find where this FSB wall happened for you and what settings you've tried from your previous posts. Please link some numbers on what you've tried or your posts seems pointless... as we have no idea what the problem is and cannot duplicate it and come back with suggestions... no offence :/

Eternal, no offense taken. I held the reasonable expectation that a $400 motherboard would outperform a $300 motherboard. So far, it has not begun to come close to the performance of the Maximus Extreme -- again, with a quad processor. I'm not speaking to results obtained using dual core CPU's. 26805 3DMarks on 3DMark06 using Maximus Extreme on H20, QX9650, 3870X2's in XFire.:



The FSB wall varied depending on the multi used: for 9x the FSB wall was 465MHz; for 10x, the wall was 420MHz. I couldn't get an 8x to even approach 4.GHz clockspeeds. I used multipliers from 8x - 11x. Vcore in .10 increments from 1.40 - 1.70 (LLC disabled, auto, and enabled). CPU vtt: 1.20-1.50v. CPU PLL: 1.60v-1.70v. NB: 1.40-1.70v. SB: 1.50-1.60v. Typically left CellShock Blue on auto settings (clock speed and timings) to eliminate that variable, but was able to boot at 4.10GHz with vdimm of 1.92 and timings set to 8-8-8-16, 1T.

If I were to list all combinations of voltages, timings and FSB speeds employed, it would occupy an entire webpage of posts with data that also could be dismissed as "pointless."

I think far more helpful would be to post your settings that allow you to run 4.90GHz stable. My apologies if you have done so already, but in reviewing the 25 pages of posts in this thread, I don't find those numbers. For that matter, I find no such figures from anyone claiming a stable clockspeed exceeding 4.20GHz.

Sadly, it would appear far more forum members are struggling in achieving stable overclocks with the Rampage Extreme and quad core processors beyond 4.20GHz than are successful. If you have found a combination of settings that surmount this obstacle, I'm certain the community would welcome specifics. You now have my settings. I look forward to reviewing yours.
