I'm running 4 gig of PC2 6400. Should I switch to 4 gig of PC2 8500? Do you think the performance gain :headexplode: would be worth it?

It would increase your overclocking ability, but other than that I doubt you'd see enough of a difference to make it worth it,

(I've been researching similar issues myself for the next MB upgrade, currently postponed till April)


whats is your primary goal and usage? (not counting over clocking bragging rights?)

Gaming? Everything I've been reading ends up with the same conclusion: that the GPU is the overwhelming limiting factor. Yes, you can get maybe 1-2 FPS improvement in some games. And then, only if you have a very high end GPU (880GTX or SLI) will you get that 1-2 fps improvement.
(I'm flip-flopping between 4 GB of 6400, or 2GB of 8500+. Leaning towards 4 GB lately)

Multimedia: noticeable performance improvement

day to day (web surfing, ms-office, email) - zero effect.

note: Vista ignores extended memory setting beyond pc2-800. So spending more $$ is money wasted)

Even pc2-6400 vs PC3-10000+ shows little reason to spend the $$ for PC3 now.

Now if you plan to overclock the CPU, the higher speed RAM's make that easier.

PC3 is the future. Right now, the cost benefit isn't there.

if your looking for a performance gain just save your $$ for a new 9 series card ;)

Hell of a price!

2x2GB PC2-6400 at C4 is better than 4X1GB PC2-8500 CL5.

I noticed that too just want to see what everyone was thinking, thanks.

If you're looking for extra performance.

Get yourself 8 GBs of RAM and turn off the paging file (x64 only)

I recommend this memory http://www.newegg.com/Product/Product.aspx?Item=N82E16820145176

I would get the CL4 version:

Yeah I would too...but my motherboard says it doesn't support CL4 100% and it might run at a lower speed.

Also, the one I posted comes out $40 cheaper with the mail-in rebate.

There is very little if none gains between Cas 4 and cas 5 in game and as for as I can tell there is even smaller difference in running say 600mhz verus 1200mhz.So IMO it is not worth it just buy the best brand rather it be PC2 6400 or PC2 8500,because I really doubt you will see any gains ,the only reason to go for PC2 8500 is if you need the extra for overclocking,but even my OCZ PC2 6400 reaper will over clock to 1100 mhz.One good thing about getting PC2 8500 is that you can run it at lower lacteies when running around 800mhz ,plus you don'nt need to crank the voltage to the default of 2.1v like some have .I have two set of PC28500 Corsair Dominators the old ones with the micron IC's and it says to run them at 2.1v or 2.2v ,but since I don'nt run them at there rated speed ,I just run them at 1.9v ,that way they run cooler.This is a very good set too.
