Cpu and Ram questions

[GWeasel]

I recently decided to overclock my Athlon II 240 so got it to 3.7Ghz stable on stock cooling and default voltage only to find that in Counter Strike: Source and League of Legends, it stutters with character movement and feels sort of distorted. I clocked it back bit by bit to see if it went away, and alas, the games were only content when I set it back to stock. I'm curious if anyone can explain why this is or if I am doing something wrong. I will point out that the overclocking program I used, Asrock Overclocking Utility, was supported for my motherboard, but I had to get the Vista x64 version as they didn't list it under windows 7 x64, I figured this wouldn't be a problem as most vista x64 drivers and such work on 7.

Another quirk with this comp is the ram freq. I first just left the BIOS on auto for it, and the mobo put it at 200Mhz with strange timings, something like 6-4-6. I got the manual settings off of newegg and set it all in the BIOS after this and set everything according to manufacturer settings. Even after putting the freq at 1066 as shown on product, it is showing up in CPU-Z and Speccy at 200mhz. I don't get it. At least the timings are all right now and the voltage is correct. Is this just a bad motherboard? It's working alright and shows up as 6.3 for both cpu and ram in windows experience index.

Computer Specs:
Windows 7 x64
Athlon II 240 (stock everything, for the time being)
asrock K10N78M
OCZ Platinum (2x2GB) DDR2 1066 5-5-5-18 2.2V
HD 4770 512mb
BFG 550 watt psu

It's probably overheating, don't use stock coolers and overclock.

I knew I was forgetting something, It idle's at 37 Celsius and under full burn, monitored in Speccy, it maxes at 52 Celsius. This proc runs nice and cool, and I know those are ok temps. I've seen people with similar setups using stock and getting these clocks or higher no problem on overclocking forums.

Overclock from BIOS, not with those utilities. As for the issues in games, it probably just isn't stable at that frequency with default voltage. Get Prime95 for stability testing. Leave the torture test running for a couple hours, and if there are no errors, it's most probably stable.

Thanks for the advice, any idea why my ram won't run at the right speed?

if it says 533mhz, thats because its DDR - Double Data rate, so times 2 by what ever cpu-z tells you or what ever

But therein lies the problem, it shows up at 200Mhz, as I said. I'm aware of how DDR works but this won't go to 1066mhz, it's at 400.

Check your FSB bro.

Or your memory multiplier.

Also don't take numbers from other overclockers all hardware is different even if you have the exact same components you may not be able to get the same clocks.
