4x512mb on AMD64

Burned_Alive · 23 May 2006 at 03:10

Currently running:

AMD64 4000+
MSI K8n Neo2 Platinum
1GB (2x512mb) PC3200 Geil Ultra-X running at 400MHz CAS2 5-2-2 1T

Now ive the opportunity to get 2 more sticks the same and would therefore be running 4x512mb, are there any major disadvantages to doing this or would the benefits of having 2gb over 1gb outweigh them?

I understand i might not be able to run at 1T with 4 sticks in?

4 sticks indeed means running at 2T and you may have to set the memoryspeed manually to 1:1

Also overclocking might be limited as you are limited by the slowest stick.

The disadvantage of 2T is ~5%-10% depending on the application but the advantage is that in situations where 1Gb isn't enough 2Gb will be faster.

Its very true that it doesn't matter how fast your memory is if you haven't got enough. I ran 4 x 512MB BH5 for quite a while at 2T and as long as you have a venice, san diego or newer core CPU, then it will run fine at full DDR 400 speed. The older A64's clock the memory down to 333MHz though. Don't expect much in the way of overclocking though. Running at 2T is not ideal, but if you need 2 GB you need 2GB.

Im not overclocking at all, just running stock and its a san diego, hmmm, decisions decisions.

If you do decide to go with 4 sticks make absolutely sure the sticks are excactly the same with the same default timings or you might get boot problems.
