Live MB OC Report :: ASUS Rampage Extreme

[Mezzro]

Knowing that latest bios has problems with quads makes me happy ! Only way I could downgrade would be by using floppy, but since I haven't one I cannot do anything. Mezzro, please, could you give me some advice?

The last semi-stable setup was this:

-450 FSB with multiplier at 9
-Skew Auto
-Strap @ 266
-RAM Freq @ 1800 with 1.98 vdram
-Read and Write control disabled
-Clock twister moderate
-Transaction booster moderate
-Performance Lev 6
-V.Core 1.32
-LLC disabled
-PPL 1.54
-FSB termination voltage 1.32
-NB voltage 1.4
-SB 1.5 and 1.06
-Everything else is on [Auto]

The CPU is cooled by the Thermalright Ultra 120 Extreme, RAM are 4x 1 GB of TWIN3X2048-1800C7DFIN DDR3. How can I get it stable to 4Ghz daily? Is it actually possible? Any other suggestion?!

Thanks .

Yes, it's possible on air. My first advice would be to lose 2GB of RAM until you achieve a stable 4.00GHz OC. Much easier to overclock with 2GB than with 4GB. Leave RAM timings at auto until you get your CPU clock speed stable, then go back and use manual settings to increase RAM speed and tighten timings. Increase your strap to 400MHz. Ensure you have adequate vdimm, according to mfr specs. Enable LLC. Increase NB voltage to 1.60. Leave PPL, but increase to 1.60v, as well, if you find 4.00GHz unstable. My personal experience has been that Clock Twister and Transaction Booster do nothing to increase stability and everything to counter it. Again, just my personal experience. Others here swear by it. Try leaving them at auto first. If unstable, revert both to your settings above. Necessary vcore varies with each processor -- some do better than others at low voltages. Usually, though, to hit an OC on or about 4.00GHz. you will need at least a 1.40 or 1.45vcore. Sometimes higher. Don't go above 1.50 on air. I wouldn't exceed 1.65 vcore on water with LLC enabled.
