RAM- 3GB?

AMDX23800+ · 31 Oct 2006 at 16:41

Here is my current configuration :

Slot 1: Corsair value 512mb pc3200 cas 2.5
Slot 2: Empty
Slot 3: Corsair value 512mb pc3200 cas 2.5
Slot 4: Empty

I have 'Corsair XMS 2gb (2x1gb) pc3200 cas2' which i need to install, should i install the new 1gb sticks into slots 2 and 4 (on dual channel) and keep the old ram where it is (3gb total) or should i take out the old ram out and replace it with the new ram?

Cheers
AMD

I'm not 100% sure myself, but with some AMDs the RAM gets slowed down if you fill up all four slots.

If your just playing games I'd remove the current and put it in another machine or sell it.

Ye it's basically for gaming, also gonna get that new X-Fi Gamer Soundcard

Thanks for the advice, i think the next time i need to upgrade it will be a new AM2 motherboard and CPU

BTW what happened to the 3500 XMS CAS2 2GB???

I was going to get that and then they dissappeared :eek:

Take the old ones out, having all four slots is slower, more unstable and thus bad for OC, plus you are not going to need 3Gb anyway.

Running 4 sticks will work but you will have to run at the speed of the slowest set. You will also have to run at 2T. Running 4 sticks is probably 5% slower at most

I will go for 2 sticks then

I have managed to find the corsair pc3500 cas2 but only the Pro version at £225 :eek:

, hope they are worth it

No different from 2 sets accept for running command rate 2

lucky that my AMD still runs ram at 1:1 with all 4 slots used.

It'll still run 1:1 but later core revisions default to a 2T command rate, which gives a performance hit. Also, running more than 2 slots full on the mobo can make oc'ing harder.

Early revison cores, before Venice and SD would run 1T command rate but slow done to 333Mhz instead of 400Mhz.
