Memory Timings Driving Me Crazy

Hi guys, heres my setup

ASROCK PENRYN1600-110DB SLI 650I

GX2 9800

6GB DDR2 800

300GB SATA 2

750W CORSAIR PSU

Q6600

Right, I have been trying to get a stable overclock but to no joy, I have put it down to my memory timings. I have kept everything at stock and I am trying to find a stable memory setting, I have looked in CPU-Z under the SPD tab but it has no information on the rated memory timings. The ram is cheap ram from ebay but it has samsung chips on it though. I am very confused as I know that my memory timings are holding me back but I have no idea what to set it to.

I would like to hit 3.00ghz with 333 fsb overclock on my processor and that would leave my ram at 666 mhz which would be underclocked as it is ddr 800.

I really could do with some help on the memory timings and advice. Its driving me crazy, I am getting prime time 95 fatal errors which I have looked up and it is the ram.

Thank you guys

Try to find out how much voltage your ram can take, you might need to increase the voltage because you have three sticks of ram on your motherboard.

The stock voltage is 1.8 V, 2.2 V might be a little on the high side.I have Geil black dragon series running at 2.0 V and can take as much as 2.4. Seeing as you have generic ram you shouldn't go past 2.1 imho.
