Question about system memory vs performance

[raytang_c]

Hi

I had a system with
MSI KT3 Ultra ARU mobo with Athlon 1800+
and 1G of DDR 2700 Ram

I just got a Shuttle SN41G2 mini pc with Athlon 2400+ but I haven't got memory for it yet.

I have some questions about memory vs performance, could someone give me some feedback?

1) I am thinking if I remove half of the memory from my MSI and use it on my new shutttle. My MSI will only have 512M left. Is it going to lose performance a lot? I use the MSI mostly on playing game like Warcraft or Medal of Honor.

2) Should I instead buy new memory for my Shuttle? Since Shuttle support DDR 3200, will 3200 DDR performance a lot better than 2700 DDR? Will 512M enough for the Shuttle?

3) Could you actually feel any difference in performance when upgrading memory from 512M to 1G? Esp in playing game ...

thanks a lot for helping - raytang_c

If the memory speed is alright, then 512MB is plenty as far as performance is concerned.

You'll need PC3200 ram if you want to put your FSB at 200Mhz (DDR400).

Thanks for the feedback ..... so if I use DDR400 (FSB 200Mhz), will I able to see a hugh difference compare with DDR333 ? or just a slight difference in performance?

Only if you clock it at that speed. If you're clocking your ram at 333 anyway, you won't need PC3200, but if you want to clock it faster you'll need it; If your processor isn't locked, then changing the processor from 12*166 to 10*200 will give you quite a performance boost without overclocking anything. (assuming all your stuff supports 200FSB).
