I just got my Patriod DDR3 1866Mhz memory set and while my motherboard (785GM-E51) cannot run at 1866 I wanted to future proof as it was a great sale.

Link to mainboard: http://www.msi.com/product/mb/785GM-E51.html#/?div=Basi...
Main Memory
• Supports four unbuffered DIMM of 1.5 Volt DDR3 800/1066/1333/1600*(OC) DRAM, 16GB Max (Does this mean I need to OC my MB to get up to 1600?



To my understanding this means I am currently running at 1333mhz. As I should double to recorded value given by CPU-z. How and is it worth it to push the memory up to the 1600? The SPD page gives values that add to 1866Mhz and then 1370Mhz but not 1600.

If it is not feasible or worthwhile on this motherboard should I put my two old sticks of memory back in? They were also running at 666.7Mhz each. They are only 2Gigs each Kingston KVR1333D3N9K2 /4G.

I mainly game on my computer if that makes any difference.

Thank you for the help!

Don't use the old ram; the 8 gb of the new ram is plenty. Mixing ram speeds may cause instability and you won't benefit from the extra slower ram. I would set your ram speed manually to 666 and overclock the cpu by about 25%. For my sempron, I change my cpu fsb from 200 to 250 and the ram speed also increases by the same percent. Then run your system for awhile, and if it's stable, increase the cpu fsb some more, but do it slowly and test again.

Sorry if I am missing something as I have never overclocked anything but my graphics card before but is my ram not already running at 666?

Re guarding OCing my CPU I assume its in the BIOs? Is there a special program that will let me overclock it? My CPU is AMD Phenom II X4 965 Code Name Deneb 3400Mhz if that helps.

Since your board is amd, keep the current settings for the new ram.There's alot of posts about folks wanting to mix ram recently. It's not hard to sell your old stuff or pass it on to a family member.
