Memory OC help please..

Hi, wondering if I can get some advice here. I know I haven't got good memory here, at the moment I can't afford it so I need to OC what I have for the moment. Its DDR2 PC2-5300 A-Data memory. I was wondering how far I can overclock it, I just want to know how much faster I can make it run so that I can get a decent preformance increase until I can get some good memory in a few months. I know my processor can be easily OC'ed but was wondering how far the memory can go? Cheers.

Heres my specs..

Intel Core 2 Duo E6300
Abit AB9 Pro
1 Gb A-Data DDR2 PC2-5300
Foxconn 7600GT
EZ Cool 600W PSU
250 Gb Hitachi Deskstar
120 Gb Seagate HDD
Sony Dvd Rewriter +/-

Heres a print sceens of CPU-Z with the details.

you may be able to hit 6400 speeds or close to it.youll have to give it a try to find out for sure tho.

For some reason it wont go past 350MHz with a 1:1 ratio with the CPU, which ends up at only 2.45GHz. But it's all running stable for now, I will try and increase the voltages bit by bit tomorrow see how far I can safely get
