Corsair XMS2 6400Pro Review

[Capper]

Corsair has been manufacturing high-performance memory since 1994. While Corsair produces some other high quality components, most notably flash memory and watercooling kits,Corsair is definitely best known for its flagship XMS Memory Series. Today we are going to focus on the Corsair TWIN2X2048-6400Pro, a 2GB kit from their XMS series fitted with top of the line components and activity LEDs in the heatspreaders.

Bo just finished up a review of Corsair's TWIN2X2048-6400Pro, if you are looking for a great looking 2GB kit of DDR2, check it out

sweet kit man! i had some of the DDR 400 flavor when i built my first system, those LEDs are pretty wicked

Awesome review! Those LED's are definately sweet. Could you maybe run some benchmarks at CAS 4 too and compare to CAS 5 at DDR800? Maybe just like SuperPi and a game benchark? I'd like to see how much that affects performance at those speeds.

Yeah rad kit for sure. I'm not a fan of the leds, but the perfs are there. :)

Maybe I'll change the graphs and upload them all at once to replace the current ones.

Cool, thanks. But could you do DDR2-800 speed at CAS 4?

[RangerXLT8]

The sticks would not post DDR-800 CAS 4 with the voltage range I was using. They are rated 800mhz 5-5-5-12. To run CAS 4 we're talking atleast 2.3v, which is too much for some DDR2.
EDIT: Blake I was reading through some other reviews and found Later revisions of these sticks running CAS 4. The performance gain was moot. Read about it here.

OOOHHH, ok, I must have just misinterpreted something in your review then, I thought you got them to do CAS 4 at DDR2-800 speed.
Thanks for the link though, the performance difference between the two really are neglegable; thanks! :thup:

I don't think CAS4 would've made any difference, I can see that CAS3 533 & CAS5 800 both at 200mhz are not difference at all, so CAS4 960 & CAS5 960 would've had the same results IMO.

Excellent review, that goes to show that latencies are pretty much meaningless when DDR2 is all about high-frequencies.

Frequencies such as: 1034mghz & 800mhz CAS4 or 362mhz CAS3.

Hello, I am new here and I had some questions about this review.

I have the same C19-A SLI motherboard and I noticed that you noted you were able to overclock your Pentium 920 to a 288mhz fsb setting. I have just purchased a 920 and am waiting for it to arrive. So if you can supply any more info on how you accomplished that FSB on this board, I'd be very thankful.

My memory is DDR2 533 at 600........but I've never been able to get above 250 mhz fsb. All people I have talked to have never been able to get above 250mhz. So I was very happy to see that you had accomplished it.

Please let me know how you did it. Thanks!!
