but the timings are different. im guessing like the OP that just set them both to the lower speed settings and it should be fine.

Considering upgrading to 8GB for the sake of £25

I currently have 2xXMS3 in my machine. Assuming I setup timings manually to that of the lowest spec of the two, is this likely to be OK?

Well that was my thinking too and it worked for me. 4 x 2GB, two different sets (Both G.Skill though) , timings and voltage individually set to those of the weaker modules. DDR3 1600s, OCed to 1666 MemTest 24hour stable.
 
Good stuff. I am doing this too. 4GB of Obsidian and 4GB of Special Ops.

Should I mix the different RAM between channels or should I put one type in one channel and one an the other?
 
I have mixed ram on multiple systems before. The easiest way is to install and manually set timings for the slowest modules first. Then add the faster ram and all should be okay.
 
I just found this.

From that it looks like if you want to mix RAM types then you have to match the RAM between the channels. i.e. each channel should be made up of one stick of each type so that the channels overall are the same.

Do others agree with this?
 
Your best bet is to sell your current ram on the bay or MM and buy x2 sets of the OCZ.

The sale of your current memory should more or less make up the cost of the 2nd set of OCZ and you'd be left with 8GB of matched memory.

That's what I'd do anyway.
 
Well, I've ordered it anyway.

If the OCZ stuff doesn't work, I'll stick that on eBay and probably make more than I paid, then just grab some XMS3 with the proceeds :P
 
Or stick the XMS3 on the bay and buy another set of OCZ with the proceeds.

They'll probably sell for more than the OCZ, too.

GL either way.
 
Dropped the ram in (Matching ram on each channel), worked first boot, no need to adjust timings as the board automatically took the highest timings.

My overclock is still fine, too.

Job done :)
