Corsair twinx2048-3200c2pro (2.5-3-3-6 stock)

or

Crucial Ballistix Tracer (DDR PC4000 3-4-4-8 )


Will be 2 1 gig sticks.

Are you up for recommendations or just pick between these two?

IMO I would go with the Corsair because it has lower latencies and the few reviews I have seen they overclock the best,Plus a lot of the PC4000 defauts to 2T witch sucks.and I thought the CMX 1024C2 was 2-3-3-6.

Not on an AMD system ... its 2.5 CAS on AMD's :(

the ballistix is supposedly capable of 2-2-2-5 at ddr400 speeds. however, the 1 gig sticks might not hit those timings. i heard the 512mb sticks can hit those timings.

Well I just picked this up for myself and it was a damn good price. I have yet to test them as Im still waiting on them to arrive. I started a thread and everyone chose this over corsair hands down.... its OCZ. Click on the link for price and specs. Looks like some kick ass ram... check it out :) Great timings and OCZ from what I hear overclocks nice too.

The Corsair .. it has lower latency.

The corsair is 3200 memory, that is why it has lower latencies.

Really, Corsair memory is a hit and miss when it comes to good modules. Sometimes they use good samsungs, sometimes not. They also have alot of compatibility issues with certain motherboards. My memory has been a pain in the ass just to get it to run at its rated speed of 500MHz. It just will not do it.

The ballistics is very good memory, if you plan on doing any overclocking with a 1:1 ratio, then go with nothing less than the ballistics. The corsair will not give you a guarantee OC over 400MHZ

Actually, I can run mine at cas2 with no problems, although I do realize the website says 2.5 for amd.

Wasn't that "warning" for older athlon xp systems?

Crucial Ballistix Tracer is PC4000 Corsair its PC3200 only. I can run my Tracer at 2225 1T PC3200 on a i875 chipset or 2.5225 1T on my actual NForce4 Ultra (Shuttle SN25P) and only with 2.68V instead of the 2.8V recomended. At their rated speed they are running 3339 1T (3335 capable but get better results at 3339)

I am talking about the 2*1 Gb kit.

Hope it helps

I have Corsair PC4000XMS and it has a hell of a time hitting 250 thats with the timeings at 3-4-4-8-2TMy new Corsair XMS3200XL has no problems hitting 250 and more with good timeings 2-3-3-8-1T.To me the Corsair PC4000XMS is just a waste of money.I have XMX3200XL version 1.2 ,I heard that version 1.1 did'nt overclock as good.

The higher PCxxxx ratings seem to be mostly useless in practice. You see a lot of the best overclockings on RAM rated PC3200.

Saving RAM on money and invsting elsewhere is usually a good idea.

Isn't the whole XL line TCCD?

I've the same problem about making the right choice for my needs.

"Corsair PC32000 vs Crucial Ballistix PC4000"

I've read that Corsair overclocks very well, higher that 250MHz with CAS3. In the other hand, i've read that Ballistix 2GB kit doesn't overclock well.

The link with info was posted here in this board: http://www.amdzone.com/modules.php?op=modload&name=Sections&file=index&req=viewarticle&artid=163&page=1

The problem, as always, is that overclock is not guaranteed, & perhaps, the couple of sticks that you get from Corsair, won't run at 250MHz, or with problems.

If you just plan to overclock for free, prolly Corsair is your best choice, but, if you plan to run your memory bus at 250 MHz, with no surprises, Ballistix for sure.

About the latencias, well, 200 MHz with CAS 2 vs 250 MHz with CAS 3:

CAS 2 / 200 MHz = 10 ns
CAS 3 / 250 Mhz = 12 ns

64 byte data transfer with 2x 64 bit channels (Dual DDR)

((64 byte * 8 bits / 64 bit wide) / 2 channels) / 400 = 10 ns
((64 byte * 8 bits / 64 bit wide) / 2 channels) / 500 = 8 ns

So, to fill a cache line you need:

CAS2 400 MHz -> 10 + 10 = 20 ns
CAS3 500 MHz -> 12 + 8 = 20 ns

So, virtually the same speed for the worst case.

Of course, this isn't exact & i've ignored the other memory timings, but, as you can see in the link, for the memory latencias, Corsair CAS2 @ 400 & Ballistix CAS3 @ 500 have the same latency for your CPU.

Think that i'll finally buy Ballistix next month.

Opps nevermind. Sale's off.

On a side note if you have a DFI board that can put out a lot of voltage try Mushkin Redline. They have 2-2-2 DDR 500 sticks, as does OCZ.

All the Corsair 3200XL may be TCCD chips but a couple of reviews I read said that when it first came out the version 1.1 overclocked alright but when they went to version 1.2 they just overclock a lot better and higher and ran higher with lower latency.
