I intend to upgrade my XP 2.0 (SDRAM) to a P4 3.2 (DDR), not Prescott.
I wanna buy 1GB dual channel kit, but does it worth paying a lot more on the lowest latency time memory?
How fast my system will run with a 2-2-2-5 or 2-3-2-6 comparing to a 2-3-3-6?
Considering that I'm not going to OC, just play games, office aplications, and in the future some digital image editing.
My options are very limited to:
Corsair TWINX1024-3200C2PT 1GB
Corsair TWINX1024-3200LLPT 1GB
Corsair TWINX1024-3200XLPT 1GB
If you do not plan on overclocking, lower latency won't mean a whole lot to you. I think there is way too much hype associated with Cas Latency, if you using the computer for games, office, and imagin then you need the memory more then you need faster timings.
Crucial Performance Lab
The Memory Experts(SM) at Crucial Technology is now on board to give you straight answers to your memory-related questions.
Interesting to note however that the <A HREF="http://www.corsairmicro.com/corsair/products/specs/twin..." target="_new">Corsairmicro </A> (*PDF file) website claims that the XL series has 38% increase in performance using some application using the PCmark04 benchmark over non-xl types of memory. the latency of this ram is 2-2-2-5. Not a bad increase even if is only on <i>some</i> applications.
...and I'm not saying it's bad memory either because it's great memory. But to say it's better than another even when it goes against documneted benchmark tests is maybe liking it a little too much. hehehe.
Corsair and Crucial both make great memory, as do a few others. Nobody would go wrong using either of those. In practice if you had identical machines except for the memory you probably wouldn't even be able to tell the difference.
OCZ also makes good RAM. I think eventually dual channel will have some real benefits but now they aren't ahead by leaps and bounds. Stick the performance to price equation on this one I think unless you really want it. Then go for it! :smile:

Low latency ram can make a big impact as it lets you tweak the performace settings in your bios more. Take for instance if you have a Abit IS7 motherboard. Low latency ram not only allows for you to tighten the timings, but it allows you to enable and crank the Gaming Enhancement all the way to F1 settings. Pop in some 3-3-3-8 PC4000 like my pro series Corsair XMS, and you can no longer run gaming enhancement at all, never mind having to relax the timing a bunch. Running 3dmark2001se, I saw a big difference from Corsair PC3200LL with F1, and PC4000 with no gaming enhancement. Can't rememebr the amount exactly, but it was clearly significant.
