[SOLVED] Choosing My DDR2-Ram

jezzer · 01-02-2008, 03:41 AM

Hi Ive been trying to choose some nice new ram for my system and i realise that my ram must be identical. My motherboard is an asus P5N-SLI and takes upto 667mhz ram. So immediately i came up with this..... http://www.dabs.com/ProductView.aspx?Quicklinx=4NVP&CategorySelectedId=11150&NavigationKey=11150,385080000,4294959063,4294953914&InMerch=1
This is non ecc as the ram in my motherboard currently is not ecc (2XElixir M2Y51264TU88A4B-25C). While investigating my current ram i realised it was in fact 800mhz so i realised my motherboard must be clocking it down. Will This Affect My New Ram I hope to get and is this ram suitable for gaming?

IMPORTANT! Before You Buy Memory

use the crucial link

I dont want crucial
lol is the ram ive chosen ok with my setup

hmmmmmm you missed the whole point Speedster was trying to make

the unequivocal way to determine if memory sticks are compatible is to use the manufacturers website / memory selectors

there is no way to tell if OCZ sticks will play nice with the sticks you have

/ nobody tests for such type of memory mixing

if you are running a 32bit OS then you are wasting your time getting 4 gigs of memory / 32bit windows cant use 4 gigs; it doesnt have enough memory registers! (often times 4 gigs will run; but with crippling performance) the best you can do; if it works; is to use 2 x one gig sticks AND a matched pair of 2 x 512 sticks

if you use four sticks though, you must check to be sure you can bump up your ram voltage to run 4 sticks / not all motherboards allow you to tweak your ram Vdimm in such a way.

personally i would get 2 x one gig sticks of DDR2-800 corsair XMS memory even though your board will kick them back to 533mhz (get the sticks that are 4-4-4-12)

at least you can tweak above 533mhz with alittle voltage bumping and latency tightening

personally I would stick with corsair and crucial right now; IMHO OCZ has lost a step since the conroe CPU's have arrived ?

I have seen too many instances difficulty with OCZ ram on newer systems, that gets old in a hurry

you can always sell off your old or un-needed sticks on ebay / DDR2 is very reasonable now days !

best regards
