That could definitely be the case. Have you double checked the RAM speed and timings in your BIOS? Make sure they're in spec.
A good idea would be to run Memtest86+ for a couple passes
I put the 4gb back in and it seems to be even more laggy again. It was still laggy with just 2gb but for example, portal was smooth for 3 seconds then started lagging as before it lagged right away. Maybe I have the wrong ram or something?????
This is the ram I have : http://www.canadacomputers.com/product_info.php?cPath=24_311_312_611&item_id=020537
Is this recommended or compatible with my rig??? or do I have a completely defective 3 set of ram....
I am running mem test and it has already went through one pass (took about 39 minutes) no errors yet but I cant tell if its running at full or not because I'm not experienced enough yet so I dont really know what I'm looking for...
Ran through 2 passes but no errors. I really did not know what to be looking for other than that so I wrote a lot of it down. If you need any info to help me determine the issue. Maybe the ram is working but its not compatible or something?
If I cant get it running tonight I'm going to bring it in and they can try to determine the issue.
If that issue can't be solved I'm going to sell or trade it.
