Previously I had a 1GB 800 Mhz stick in my PC and ME2 would give me quite playable frame rates at 1024X768 resolution. Recently then I added 3 more GBs of RAM to my system (a 1GB stick and a 2 GB stick) all clocked 800MHz. After this upgrade, I was hoping my game's performance would increase, but to my utter surprise, the game actually degraded in performance!

I checked with both CPU-Z and Bios and both of them report my RAM modules to be working in Single-Channel mode, as I read somewhere that this type of problem comes from dual-channel RAM, but with unmatched timings. At first I thought, re-installing might help, but I tried 3 times (with all the DLCs) but to no avail. I updated my DirectX and Graphics driver, but still no improvement. But after the adding of the extra RAM, my game load time has decreased and other games have even gained in performance. ME2 seems to be the only one that doesn't like the extra resources.

I running on Win XP Home SP3. Any and all help would be highly appreciated.

Rest of your system specs? There might be a bottleneck somewhere.

CPU - Anthlon X2 4800+
RAM - 4 GB (1+1+2)
Motherboard - GA-MA78GM-S2H
IGP - HD3200
HDD - Seagate 360GB

I just added more RAM. Before it was the same config and the game would run pretty decent, enough to finish 4 playthroughs. But the moment I added more RAM, the performance dipped.

As an IGP, I presume the 3200 is using your main RAM as its VRAM. Therefore, changing around your RAM also affects your GPU. Can't tell you why it has in this way, though.

Are you sure single-channel is what you should be using? If the timings are the same I believe you're supposed to be better off with dual channel.

Seems that 2 gig stick maybe hindering your system. Most MB's require the same mhz AND ram size. you mixed 2-1gig sticks with a 2gig stick. try removing the 2 gig and see if it helps.

Yes, the IGP is showing the graphics memory as 700MB, from both the DirectX dialog and the Catalyst Control Panel. Previously it used to be 320MB. As for the single-channel, I would've enabled it if I had all four as 1GB sticks. The 2GB stick has a slight higher timing than the 1GB. That is why I avoided it.

Hmm...will try it then.

Just tried after removing the 2GB RAM stick. The other two started in Dual-Channel mode, but there seems to be no performance difference. It still performs lower than what it used to. Guess I have to get a discrete GPU.
