Default Dual Core = game probs?


I have had my X2 4400+ for about a month now and i have recently installed Need For Speed Most Wanted and sometimes when i load my game up it seems to jump alot.. not lagging its like every 2 seconds the game will go doubble speed..

it also happend in CS.. i am sure i have played CS on this cpu and it aint gone dubble speed..

but see the funny thing is.. if i alt tab out and set the game process CPU afinity to only 1 core the game will work fine.. but when afinity is set to both cores the game seems to doubble speed every 2-3 seconds for some reason.

It does'nt seem to happen all the time just on the odd ocassion.. happend twice today but as soon as i set the afinity to 1 cpu it works fine...

Our systems are similar, I have no problems in Quake4. Possible driver issue somewhere, incorrct memory timings, could be a lot of things. I don't have NCQ on either...

ABIT KN8 Ultra
AMD X2 4400+ @ 2.5Ghz
XFX 7800GTX Fac OC at 490/1300
2x512MB GeiL PC3200 2x512mb PC2700 Micron Tech running (All running Dual Channel at PC2700 128-bit)
1x160GB Seagate IDE HD 8mb
Sony DRU 800A

I am using 81.98 drivers for my video card, with direct x 9c december vesion installed.

(As u may have noticed above my SATA HD died on me about 2 hours ago, i have just sent it off to be replace and this is the first Seagat HD i've ever heard that died .... so anything you guys suggest i will not be able to test until the replacement HD arrives.)

I am guessing you might point your finger at the ram mixing but i was still having the problem befor i added the PC2700 Sticks.

I am also experiancing Random Reboots normally when i have a full screen appliaction running like a game or a movie i am wathing in full screen... but you never know this all could be to do with my HD that just died....

the only solution i have found it setting the affinity of the process to only 1 core.

I love how in console games it's called, "Glitching" & in PC games it's called "Hacking".
