Think your overclocked system with 4GB+ ram is stable... Try this

I thought mine was until I tried this combination. It problem is that no single stress testing app can use all the ram at the same time. So one alone is no good.

Prime 95 Blend + 2 x HCI Memtest

With 8gb ram you might need 4 x HCI Memtest.

HCI Memtest is a great tool (better than standard dos memtest86 as it can test more ram at once). It runs in windows and in my experience it finds a fault a lot quicker than standard dos memtest86.

Already use it since long time ago
Couldn't be arsed to reboot just to run a memtest86, you can do a x64 mod on the .exe too so it can address higher amounts of memory as it still is a 32 bit prog, for some reason I couldn't assign 2gb to it but after the modification it works fine.

Although I haven't run a test like this and can't yet I will try when I can. When I used to Prime I just used to run it and then put a movie on or play a game or browse the net
It was stable after that so I have a good feeling that it'll still be stable
