G.Skill 2GBHZ PC4000 Preliminary test results w/Opteron 180

After having to RMA 2 sets of Crucial Ballistix 2x1gig I decided to give some UCCC another try.
The G.Skill 2GBHZ PC4000 is going for around $220 right now and after seeing some of the other
results being posted here I couldn't wait to try it for myself.

I got these last night and just got through installing them in my work rig so I've not had time to do any real testing yet.
I've not had time to test for max OC with the ram or the max with tighter timings but will have time tomorrow.

I run my Opteron 180 at 3.1ghz 24/7 so I decided to start off testing with 11x282 which would be the ideal setup for my rig.

To my surprise they worked right off the bat, didn't have to change or adjust anything.
Didn't even have to change the ram around in the Dimm's !

I'll admit I took a shortcut and borrowed some settings from this thread by Andre Yang

You can't get much easier than this, plug N play @ 282mhz ! :D

I'll have some time tomorrow afternoon to see where they top out at and if I can get the timings any tighter.

I'm just glad to be back up and running with 2x1gig !!

Wow, looking good....good to see UCCC turning around (again-ish).

I bet it's good to be back on 2GB....I've been off for about a month and it's killing me (and my D2OL production).

Nice result!!, can´t do anymore with more vdimm??

Why must G.Skill tormet me like this! Damn you and your amazing results, while I sit here with a DOA stick!

I've not tried ANYTHING else yet, just didn't have time today. I took a long lunch and did this ! lol

I just set it at 282x11 and manually set the timings and it worked ! hehe

I'll take some time tomorrow afternoon and see how high they can go, I'd also like to see if cas 2.5 will work around 250mhz and If I can improve the timings any at 282mhz.

Woot..very nice major. 282 right out of the box.

can you run 3D stable at 282 ? Mine not quite stable@280. Have to went down a little bit to be stable.

Waiting for more nice result from you major :)

I ran Auquamark without problems but didn't try any other 3d benchs, I will be sure to do that tomorrow afternoon. I'm not at home tonight so can't do anything else until then.

BTW Auquamark did +/- 125,000 :D

Here are 3dmark05 and Aquamark scores, its 100% at 282mhz

Going to see where the memory tops out next, brb

nice Clocks Major! :toast:

Very nice results Major.

I ordered a pair today, although they're so expensive compared to what you guys pay for them in the US.
A 140$ price difference is a lot for the same sticks. :stick:

Man you're lucky, 282MHz 3D-stable just out of the box!! I wonder if my HZ will do something near that, i'll have them tomorrow :)

Looks very good so far, George :up:
I bet you will find them quite flexible once you get to play with them a little bit more ;)

Incredible!!! what's your bios settings because it's hard get stable at 270 with mine?

Look at my A64 tweaker settings, you may need to change the ram around in the dimm's too. Sometimes that makes a big difference if you have a weak stick.

Here is the max Pi32 I could get out of it, 287mhz.... I'm open for suggestions on Tref and drive strenght if anyone knows any magic ! lol

http://www.xtremesystems.org/forums/...9&d=1134590793

yeah, i already noticed "the weak stick"... in one sort, they wouldnt go up to 255 and if i turn aroud the ram's in slots, they are able to pass pi at 270...but 282, it's amazing

if you want can you the sam tests by using 166 or 183 divider because i use 166 divider to o/c at the max

me : 9*312 ram at 257 (166) and i want to do use 183 divider to set ram at 280

i think some timings will change 'cause a different divider of your pics

Congrat. Major :toast: :toast: Very nice result you got there :)

Yesterday, i managed to get my HZ to 285@2.68 V. It passed memtest, 3D and other progs fine - but I got BSOD around an hour later.

What's the max vdimme for HZ, 2.7 or 2.8 ?

UCCC is very sensitive to small changes in Vdimm, I'm running at 2.6v 282mhz right now. May even be able to do that at 2.5v ?

Actually, I'm running right now at 310mhz HTT x10 using the 180 memory divider which gives me 282mhz. Not sure what you want me to show, but I'll be glad to run any test you want.

My 180 likes the 10x multi, with the 11x I have to use a higher Vcore with it to obtain stability at the same OC so I'm running with the 10x.

What happens if you set both or either 4's, to 3-3-3? If this ram could run 3-3-3 at 280, then it could pretty much replace balistix altogether.

Do these UCCC RAMs need any sort of active cooling at those high frequencies? :) Worried if they would get toasty.

I'm intending to get a pair to place in a board which has RAM slots for dual-channel next to each other (DIMM1 and DIMM2) unlike Asus boards which are DIMM1 and DIMM3 for dual-channel.

active cooling is never a bad idea for any memory. they don't seem to get too warm, but i decieded to error on the side of caution.

nice results guys
Soon ima test the max of these PDP's out
Im hoping for 270ish
2.5-3-2-5 @ 255 so far max Ive attained, with a 10x multi

Well thats what I'm going to test today, I'll see what kind of timings I can tighten up. but I know they wont do 3-3-3 at 280mhz. I had another set of OCZ PC4000 UCCC that would do Cas2.5 at 250mhz, not sure about the secondary timings.
