Live MB OC Report :: ASUS Rampage Extreme

[Expat GriZ]

I might pop by too watch the masters at work and swap ya board Expat

I can't speak for Zeus but you've got the wrong guy if you think I'm in that class.... I never thought the board had it in it.....High FSB was always a problem for me. The only reason I think its still alive is due to my OCD insulation & a dab of Owens Corning grease in the socket. Once I've got the "shed" built (thank you Belgian slow poke law makers) you can come by and "contribute" you Belgian Team GURU!!

I know I'm a bit late to the party but I have a REX now as well.

First kit I'm testing is the blue Cellshock DDR3-1866 CL8 with D9JNL chips, it's the same kit CryptiK is using.

This is the highest 32M-stable speed I managed on CL7-7-7-14 1T, VDIMM is 2.04V:



Now I'm working on CL8-8-8-24 1T, but I can't even get it 32M-stable at 1000MHz with 1.90V, with the same subtimings CryptiK is using. Even on 2T with even more relaxed subtimings it's impossible.
The specific DRAM skews that worked well at CL7 don't work at CL8.
What's your secret?

Oh Rex sweetness I miss her already.

There are loads of settings that can impact ram stability mate.

Nice run Don_Dan.

you should be punished !! running a rex sub 600FSB is just cruel !!

Got a new one /w new E8600, can't wait to try it out.[had it for some time.] Got some Kingston 1x2 1866 cas 8, micron gts. Hope that works out.

I have the swify block for the stock board cooling. Good enough, or should I go further cooling the board?[full coverage blocks= $220]
I want to try dice on it this summer. Keeping it on a bench for a while.

Thanks Jor3lBR!

Leeghoofd, I'm working on it!

Today I changed the thermal compound under the heatsink, the NB was only covered 1/4 by the original paste. Temps dropped about 13° C.
Some screws were so tight I was afraid of damaging some traces in case of slipping off a screw, but everything survived.

This is still the D9JNL kit, testing CL8-8-8-24 2T, 1.95V:



32M at 1000MHz CL8-8-8-24 1T is still not possible, how high are you guys running vNB for that kind of stability? I'm at 1.44V right now. Too low?

Then I switched RAM kits for the black Cellshock DDR3-1800 CL8-7-6-21 kit, which is using D9GTR.

So far I managed a 32M run at 920MHz CL7-6-5-15 1T at 2.14V, which is not that great...
Subtimings are very loose ( auto ), more tuning and possibly higher clocks tomorrow!

Try the new 0002 bios mate ( it has Tref values ) it could help you squeeze them few extra mhz... I never realy tried 500FSB stability on this board... but went straight for 600FSB and around 2000mhz. I topped at +/- 1980Mhz no matter what NB voltage. Memtest would always error out after a few passes...

For high clocks seems the 266 strap is favourable on my board. This REX is in 3D better than my previous one, but FSB is fully blocked at 635... bummer

its good for 500fsb for 24/7

where did you find them selling these new? thought these boards were discontinued a while ago.

i also had the swiftech block that goes right on top of the HS assembly. although it does work somewhat, it's still not as good as putting on a block that directly cools the NB. with that sock heatsink assembly, it looks like an awesome cooling solution, but heat must still travel though several layers before it gets transferred to the water. full cover WC board is much better, although it also costs much more.

edit: here, post #38 from this thread accurately describes this lol
