P8P67 M PRO memory upgrade

genicide · 29 Jan 2012 at 12:57

I have the P8P67 M Pro which I bought from OC last year as part of an overclocked bundle.

The bundle came with 4Gb of CMZ6GX3M3A1600C8 which I would now like to upgrade to 8Gb.

Should I try and get another 2 sticks of the same and is there any down side to have all 4 ram slots occupied or should I replace it with 2x4Gb sticks of something similar?

I can only find http://www.overclockers.co.uk/showproduct.php?prodid=MY-293-CS&groupid=701&catid=8&subcat= on OC site and is a stick too many :eek:

I didn't mean to put the unhappy face on the header....I'm such a noob

If that's definitely the model number of your current RAM then it sounds like OCUK were using triple kits as duals.

No downside at stock as long as the memory is similarly specced, it can affect heavy overclocking though because the memory controller is twice as busy.

I would probably just get this, if you plan to use all 12GB at once though you may need to relax the timings to 9-9-9-24. Or you could get that triple kit you mentioned and just keep a stick spare in case one dies.

Both CPU Z and AI suite show the memory part number as being the same and as for the memory used it is the one recommended for overclocking on the Corsair site.

I didn't quite understand the point about the memory controller and overclocking. Does it make it overclocking harder if you have your ram spread over 2 slots or 4? I took it that you meant it's less stressful on the system if it's spread over.

My point was if CMZ6GX3M3A1600C8 is your current memory model number then it must have been originally part of a triple pack (the same as what you linked here), OCUK must presumably have used two triple memory packs to install dual memory in 3 different machines.

The more memory sticks you have installed the more stress is placed on the CPU's memory controller so overclocking can be slightly more difficult, less sticks is better as far as overclocking is concerned.

CMZ6GX3M3A1600C8 is a triple channel memory kit not dual channel they should use a dual channel memory kit looks like they used some memory thats been lying around.

well puts more stress on the memory controller but saying that since i upgraded to 16gig i can now overclock to 4.8 where as before i couldnt.

Yeah I saw that it was a triple channel kit but if you put the P8P67 M pro into the crucial site the above sticks are what's recommended for that board.

It's all the same anyway the only difference is whether they're sold in packs of pairs or triplets, I once used 3 dual kits in my triple channel X58 system (6 dimm sockets).

If you want 4 sticks of identical memory then get the triple kit and keep a stick as spare, or if you want the dual channel equivalent with only two sticks then this is the memory you need, the memory I linked earlier at £35 has slightly slower timings.
