Live MB OC Report :: ASUS Rampage Extreme

[eternal_fantasy]

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.

4.9Ghz stable? where did I gave you that idea?... If I couldn't acheve that clock am I not credible? I guess all my board sucks as non of them clocked above 4.5Ghz benchable... seriously I think it's more to do with the CPU then the MB...

My settings are stable for 24/7 as I no longer bench, I game. Therefore around 4Ghz is where I stay. When you said FSB wall I had not experienced it as my settings once stable, adjusting the CPU multi is simply a matter of raising/lowering VCore.

Also note that just because you want to run your CPU at above 4.2Ghz, and according to you there are a FSB wall at that speed does not mean the board is FSB limited where the rest of us non competitive users are. Infact you may be the first one complaining about it here that are trying at those speeds.

The other issue when comparing the RE with ME is that the ME came out 9 months before the RE, and its BIOS matured accordingly. I also have the ME and it wasn't so smooth sailing at the beginning too.

Memory compatibility is a pretty big issue with the RE. I cannot get my CellShock blue DDR3-1866 PC3-15000 to start windows no matter what setting/voltage I tried, where it is absolutely fine in the ME. Obviously it works fine for your board.

Anyway here is my setting for 470FSB

FSB - 470
Strap - 266
DRAM - 1414
CR - 1T
6-5-5-15
Twister - Strong
Booster - PL7
VCore - depends on your CPU and its speed
LLC - Disable
PLL - 1.51
VFSB - 1.31
VMCH - 1.524
VDIMM - 1.90
SB1.5 - 1.51
SB1.05 - 1.06

Setting using kits in my sig, NB watercooled below 40C under load. 10 hour dual ORTHOS Blend stable, OCCT 2 Hour Stable, 3DMark06 2 Hour stable. All voltages lowered until unstable, then upped 3 steps as insurance. So what is 100% stable for my system may require raising voltages a little. The highest clock I've tried and primed at is 470x9, around 1.63V for my QX9650.

I eagerly awaits your review.
