PRIME 95 FATAL ERRORS

[dhicks2008]

Hi guys, im having a huge problem and its annoying, heres my spec

Q6600 at 3.0ghz 333fsb x 9
6GB DDR2 800 AT 333 X2 - CHEAP RAM FROM EBAY
9800 GX2
300GB SATA 2
VISTA 64
ASROCK PENRYN1600 - DB110 650I SLI
750w corsair psu

Basically, i have tried overclocking my pc from stock, i have tried anything between 2.5ghz - 3.2ghz and i keep getting FATAL ERRORS in prime 95 after about 20 minutes. I have tried playing with my ram timings but i dont know what they should be as it is cheap ram and it doesnt list anything in cpu-id. I have boosted all my voltages to past comfortable but still same error.

Please can you guys help me out. I dont know what to do, I cant overclock my gpu until i can sort this out.

Thanks people

Unfortunately, the 650i chipset doesn't do well for OCing quad cores. I'd go for a new MB with a more overclock-friendly chipset -- look at better-quality brands such as Gigabyte.
Also, if you haven't yet, run memtest86+ with the system under default settings (not overclocked); if you get any errors there, return the RAM for refund/replacement.

What motherboard is best for the q6600 overclocking. Ran memtest, no errors found at stock. Ram is fine , everytime i oc i run prime95 and get error on a single thread after about 20 mins , really had it with this pc, going to throw it out the window or possible run it over with my car.... havnt decided yet.

Yup if the ram is used test it. Someone is always dumping their trash on Ebay.

Ditto 680i doesnt overclock well especially quads.
