Is Corsair XMS overpriced? i see a lot of positives about it but then i see a lot of posters who are OC'ing as good with good OCZ and Kingston ram... so my question is would i be cool with any of it?

OCZ DDR RAM 512MB PC-3200 400Hz Basic Series MemoryOCZ400512. HeatSpreader. DDR400, CAS 2.5, 184 Pin Dimm, ULN Technology,REV2 3-6-3 1T Timings, DDR memory. Heatspreader, OEM, Lifetime Warranty. @ $110

Kingston KVR400X64C25/512 512MB DDR400 PC3200 CL2.5 184 DIMM Memory Retail @ 142


and CORSAIR MEMORY XMS Extreme Memory Speed Series 512MB 32MX8 PC-3200C2 With Heat Spreader
Specifications:
Speed 400MHz
Organization 64M x 64
CAS Latency 2-3-3-6-T1 is over $160


so you get some better timings with the corsair but is the performance worth the price difference? basically i have a p4 2.4 i want to reliably overclock my fsb @ 170 -175

at that speed will the timings of the xms really give any measurable difference or is it so minimal.

thanks.
 
These are some popular ones ppl talk about here, the price difference is as high as 50%, but performance difference is just a few % for PC3200, 5ns chips:

TwinMOS 256 MB PC3200 5ns chip ~ $59
Winbond 256 MB PC3200 5ns chip ~ $75
OCZ 256 MB EL 3500C2 4.5ns chip ~ $86
Kingston 256 MB HyperX 3500C2 5ns chip ~ $87
Corsair 256 MB 3200C2 (6ns chip ??) ~ $84
Corsair 256 MB 3200 LL 5ns chip ~ $92
Corsair 256x2 MB 3200 LL TWIN 5ns chip ~ $193 (two)
Corsair 256 MB 3500C2 5ns chip ~ $93
.....

In my opinion, when the 5ns DRAM is mature, they all perform within a few MHz difference, i.e. within 3%. This was very different than 6-12 months ago when 5ns chips were not yet mature, ppl willing to pay a premium.

For the already overclocked memory, how much more can we get. Recently there are lots of 5ns DRAM chips that can handle 200 MHz FSB with good price. AMD CPU can be oc by 30-50%, but memory seems to be at most around 10% (if lucky). I now realise how good and generous AMD CPU are !!!

One may argue about service, rma, and guarantee timing for the premium in price (50% ??)

I think price / performance is an important consideration in building a more balance system, than throwing money into one particular component for the last % of performance.
 
i asked this in a couple other posts but nobody answered.

two sticks of 512mb ram say at pc3200 if ya put them in your system and pushed them both to say 180mhz fsb; but one with slightly better timings - would you really get much of any performace increase or is it so minute to be for the truly anal (like myself) :)
 
you want WINBOND chips, wherever they come from, thats what you want my generic winbond 2700 does 200mhz fsb fine even with memtest86 with loose settings. i can even hit 185fsb with most aggresive settings
