Hi,

Running an X2-4400 at 2600 (260 x 10) and using Corsair XMS Pro 3500LL.

Would it be more beneficial to run at 2-2-2-5 1T at DDR400 or 3-2-3-6 1T at DDR 520 for this type of system?

I think Stock is 2-3-2-6 at DDR438.

Cheers

Hey tried super pi with both.

2-2-2-5 ddr 400 gave 32.781 seconds
3-2-3-6 ddr 520 gave 31.984 seconds

Is this applicable to real world stuff?

Does CAS make a huge difference? Highest I can get CAS 2.5 is about 250 Mhz

I'll bench a few games and get back to you guys. Thanks for your help so far.

Ok, well by stock I meant the DDR438 2-3-2-6. (actually did DDR440 and 220x10 on the cpu). Everything else I agree with you although i've had them stable 260 at 3-2-3-6 for over a week (Memtest, Prime, SnM etc).

I'm finding in general that things are marginally quicker using relaxed timings and a higher fsb. Only talking 1 fps if that. Makes you wonder whether its worth spending all that money on quality RAM at all. I guess it depends on what revision you get.

Bit disillusioned but hey ho. Lesson learned!

Cheers everyone
