Hello, I was trying to upgrade an old system and all was going perfect, but I decided to buy another 2GB stick of the same model to increase the overall systems ram from 2GB to 4GB, despite having the same part number, the last 3 numbers after the part are different and I thought maybe each stick had its own individual 3 numbers when manufactured. This new ram is smaller in height from the other 2GB but it is the same crucial brand and has the same amount of chips (8 I assume non ECC then), I discovered that the original ram is 667mhz and the new one is 800mhz DDR2 ram, before I installed the new 800mhz 2GB ram, I was able to set my FSB to 333 and attained a stable 3.5ghz OC on my Intel Core 2 Duo E7400 @ 2.4ghz, but after installing the ram, the system reports it to be at stock 2.8ghz even when I set the FSB to 333 and it shows 3.5ghz in the bios. Would it be possible to just have the 800mhz ram downclock to the 667 MHz speed and overclock my cpu again to 3.5ghz?
System Specs:
Intel Core 2 Duo E7400 @ 2.8ghz
GTX 660 1.5GB
2GB DDR2 Crucial Ram @ 667mhz (CT25664AA667.M16FG) <-- Original OC'ed fine
2GB DDR2 Crucial Ram @ 800mhz (CT25664AA667.M16VFE) <-- New ram but has 667 in part #
Gigabyte GA-G31M-E2SL
300w PSU
Windows 7 Ultimate
P.S. When I overclocked, I set everything to auto and just changed the FSB to 333 (half of 667)
