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)

I can't fine tune it that low, here's pictures of my bios, I tried raising the FSB by 0.1V, and the DDR2 by 0.1V, but the system still reported stock speeds, here's pictures of the bios.

I also noticed it says 667 and 833, I'm guessing it's the speed of each ram, if I set the memory multiplier to 2.0, it'll change both numbers to 667, but it'll still report stock cpu speeds if I use auto or the 0.1V to the FSB and DDR2

-Update: Clarification, I think the new stick of ram is 667, the 833 is just the new speed they'll run at after I increase the FSB in the bios.

Fixed it! I had a 6 pin to 2 molex powering my graphics card (GTX 660) and I only had one of the molex's plugged in (I know sounds stupid), after plugging the second one and booting up the system, it was immediately OC'ed to 3.5ghz (Also on checking bios, it's stock voltages) So everything's fixed! Best answer goes to Tradesman for trying to help, and will most likely help anyone else who has this problem, but first I'd check if all your cables are plugged in ;)
