Failed Alienware now with BeastModeON - mATX watercooled build. - Page 5

post #41 of 63
...I hope the power supply issue is worked out asap - you're soooo close now thumb.gif

...per our earlier posts about the G.Skill Trident x 2400, It does overclock nicely without extra voltage (already had it up 2520)...just did this verified run with all 32GB of that Ram http://valid.canardpc.com/show_oc.php?id=2647107 smile.gif which also overclocked the memory slightly. Are you still using the G.Skill Trident X 2400 or has that changed now ?

...and more pics please of the installed water-cooled 690 SLI GPUs - tx -

All the pics will come tommorrow smile.gif the company accepted the fault today and I have a brand new power supply! Woot.

Was struggling to get above 1866 on my ram today. Will need a hand with that smile.gif

Got my professor to a stable 4.9 GHz today at a max temp of 66 degrees. Let's see how that changes when my second 690 needs cooling. GPU topped out at 36 degrees on max load as well scored 17900 total in performance of 3D mark as well. So not a bad start to my overclocking smile.gif

1866 for the 2400 G.Skill Trident X ? You may want to check DRAM voltage settings as the 2400's take 1.65 v as stock

I will check, I only tried for about 15 minutes really. And this is the first time I have ever overclocked ram.

I will post tomorrow when I find out smile.gif

What settings would let me clock at 2400? The computer failed to boot above 1866

First, a clarification: The 'natural' speed of the Ram you are using is DDR 3 2400 Mhz ? ('1866 sounds more like overclocked DDR 3 1600), i.e. your Ram is G.Skill Trident X DDR 3 2400 per package, right ?

Assuming that is the case, once in the Bios, go to 'advanced options', then 'AI Tweaker'. Near the top, choose 'XMP' and that should automatically call up the per-SPD natural clock speed. Further down on the same page is another option for Ram speed, that's where you choose from a drop-down menu, i.e. DDR3 1600, 1800, 1866, 2000, 2200, 2400, 2600, 2800, 3000 etc if you want to choose a non-stock per XMP speed.

Also note that DDR3 2400 has an actual speed of 1200 Mhz, DDR3 1600 of 800 Mhz (as it is dual channel, at least on the Z77 / Ivy Bridge boards I am using as a basis for comment here).

If you go to CPUID CPU-Z (a must-have for your OC efforts) and click on the memory tab, you will see the actual frequency. On my Sabertooth Z77 with Trident X DDR3 2400, CPUID CPU-Z memory reads 1200 Mhz.

You might also want to download MemTweakIt, i.e. per Asus ROG

Thankyou smile.gif that was exactly what I needed. The ram has been set to 2400 and is up and running.

The system is in full quad sli. So time to do some tests and take some photos biggrin.gif

I'm still working out how I can manage my cables and I need to sleep the cables to the radiators. But here is my half completed working build smile.gif





Alienware provide crappy management. But I will find a way to make it pretty smile.gif

At the moment. 3930k processor is clocked at 5080 and running relatively stable. More tests to come.

GPUs are highly clocked. And ram is comfortably at 2450 MHz

I am not sure how to get my processor much higher but to keep temps stable I would need another 480 rad. It is currently topping at 82 degrees above 5ghz.

3D mark was scoring around 25k, working on getting that a bit higher.
