That is great news!
You showed good initiative with troubleshooting to notice the lag and use CPU-Z to find the problem and make adjustments. Could you list the make and model number of this "new" memory you're trying?
I'm under the impression that the OCZ2
G8002GK RAM was installed when you first built your machine 5 to 6years ago and it was running fine until recently which caused you to start this thread, is that correct? If it is than something happened to upset your operating system (OS), CMOS, and RAM. Do you have surge protection?
Since we were able to straighten out your OS with A Guy, and NoelDP's help and you reset the CMOS you could try the "old" OCZ2
G8002GK RAM again to see if it would be stable and not cause more BSOD's. If you get a BSOD with just changing the RAM the old RAM may be irreparably damaged even though memtest says its okay. You could try taking the RAM to a computer repair shop to have it tested if they have a
dedicated RAM tester like these.
I searched for the OCZ2
G8002GK in the OCZ forums
Search Results for OCZ2G8002GK settings - OCZ Forum
Here is a search of the OCZ forums using your G31M-ES2L MB:
Search Results for G31M-ES2L and OCZ2G8002GK - OCZ Forum
Both searches especially the latter with Gbyte MB's show instability with OCZ RAM. Maybe unfair because of the different MB and timeline, but this is from seven years ago:
I really doubt there is a permanent solution for now. OCZ is still working on resolving the problem. Gigabyte mentioned to me that even though your system could boot, your OS will not be stable. I wish this is not the case.

If your still interested in trying to boost the performance of either the old -
if it still works - or new RAM you might want to start with this:
A Newbie's Guide to Overclocking Memory | Overclockers and take note of the related guides listed at the bottom of the article under Related Posts, especially #3, overclocking is too involved to discuss in this thread, although you could try in our
PC Custom Builds and Overclocking - Windows 7 Help Forums.
If your serious enough you could join either the OCZ or Overclockers Forums whatever you decide either in our Custom Builds and Overclocking forum or the two above be prepared to know settings and terms of:
