Hey Guys

Bought some ram last night to add to my 4 gig I already own but realised the ram I just bought is a little different from what I already have (yes I bought in haste). Currently have the OCZ DDR3 12800 with is triple channel and just bought the OCZ Gold 4GB (2x2GB) DDR3 PC3-10666C9 dual channel.

This is for a I5 760 system with a ASUS P7P55D EVO S1156 MOBO which I thought was dual channel anyway.

Will this work or will it cause it to be unstable
 
RAM isn't dual or triple channel, it's the memory controller and how the RAM is fitted to the motherboard which determine that.

Your processor has a dual channel memory controller.

If you had "triple channel" RAM and you've bought "dual channel" RAM then presumably you now have 5 sticks and the motherboard has 4 slots.

If you want to get it working together then here's something to start you off:

Put 2 sticks from the "triple channel" RAM kit in slots of the same colour, say the blue ones.

Put the 2 sticks from the "dual channel" kit in slots of the same colour, say the black ones.

All the RAM has to run with the same speed, timings and voltage so without overclocking the new RAM you'll have to run it all at 1333MHz.

You'll need to set the timings and voltage to something that both sets of RAM will run at.

sorry to hi jack but I have a similar question. currently using 2x2gb of xms3 and I have 2x4gb of hyper x coming tomorrow.

can I use them all together for 12gb? I'm aware that the hyper x is 9-9-9-27 whereas the xms3 is 9-9-9-24. I know the corsair will run at the kingstons speed but will everything work properly?

thanks :)

You should be fine doing this as long as all the RAM runs at the same speed timings and voltage.

You want to put each set of matching RAM in the same coloured slots. So, for example, the 2x4GB in the black slots and the 2x2Gb in the blue slots.
 
yep thanks for the advice too surprisingly know little about ram specially now there are heaps of varities on the market
