Choppy performance after upgrade

[Darkanian]

I'm currently using an Intel DG33FB motherboard and replaced my 2 1 gig sticks of ram with 2 PNY DDR2 PC2-6400 2 GB sticks. I've checked the BIOS and my computer and they're both registering that I have 4 gigs installed but I'm getting worse performance than before

What are the timings (ex. 5-5-5-18) for each set of RAM? You really shouldn't notice a difference, though. Is your performance choppy in desktop applications or gaming?

I'll admit I'm not the most tech savvy person so where will I find the timings? and the performance is choppy in both gaming and applications. Noticeably in any sort of video it's in a constant start stop motion and jsut a noticeably lower performance in gaming

install cpu-z and check under the memory tab

what video card are you running? do you have its most updated drivers? Also try swapping in the old RAM to see if that smooths everything out - and it will tell you if your problem is with the new RAM or not

Another thing to check is by running MemTest86 on each stick individually overnight. I had one stick of DDR3 that would return a lot of errors and when I removed it that solved all my chopiness (and BSOD) problems.

I'm currently running an NVIDIA GeForce 9500 GT, yes I have the msot recent drivers. Heres what the CPUZ gave me:

I'd send PNY an e-mail with the model number of your RAM and ask what the timings are. Like Jester suggested, it might be a mismatch in timings. The timings in CPU-Z is CAS 6, but your RAM might be something different. The 6-6-6 is likely set in your BIOS as the default... so if PNY comes back and says it should be 5-5-5 or 7-7-7 or something, then jump into your BIOS and make those changes.

Post back with PNYs reply and we'll help you get the changes made.
