Mixed Memory Causing Stuttering?

[BillHicksRIP]

Hi. I'm trying to narrow down the causes of stuttering I'm getting in games like APB and BFBC2. I've just replaced an 8800GTX with a 5850 but am still getting it, albeit with slightly higher framerates. I'm about to change the CPU to a quad core but I thought I'd check if having 2 unmatched pairs with different latencies could be an issue? Would yanking out the Geil and leaving just the 4GB help?

Gigabyte GA_965P_DS3 (Socket 775) PCI-Express DDR2 Motherboard
XFX Radeon 5850
GeIL 2GB (2x1GB) DDR2 PC2-6400C4 800MHz Ultra Low Latency Dual Channel
OCZ Gold Edition 4GB (2x2GB) PC2-6400C5 Dual Channel Series
Thermaltake VD4000SWA LCS Aluminium Kandalf Full Tower
Intel Core 2 Duo E6600 "LGA775 Conroe" 2.40GHz (1066FSB) *oc'd to 3Ghz*

Thanks.

Different size of the RAM shouldn't matter but the timings should. Try and match the timings.

Well the easy answer is to take out the 2x1gb kit and check. Do you even need 6gb for anything? 4gb is plenty for gaming. I used to have 8gb and I haven't noticed anydifference in games with only 4gb.
