2x512 or 2x1gig

which would be better for ocing results, and whichever one is, what do you reccomend.

I'd say from my experience the size of the ram doesnt really affect the OC'ablility. For some Good OC ram, you want to look for something with tight timmings out of the box. You have to relax timmings for realy high oc's. Anything from corsiar is usually good. Im kind of partial to Mushkin myself. Ive had good experience with them.

Overclocking RAM can happen in 1 of 3 ways: you can tighten the timings, you can raise the memory speed via the HTT/FSB, or you can do both at the same time.

On thing worth noting is the effect of 1T v. 2T command rate. 2T command rate can open your RAM up to higher speeds, but the hit involved can be substantial.

2x512MB OCZ 3200VX @ 416MHz rivals 2x1GB Corsair XMS 4000PT @ 500MHz in most Sandra memory benchmarks and the OCZ can play HD content better than the Corsair. Both were 3-3-3-8, but the Corsair ran at 1T and the Corsair ran at 2T.

Running your ram at the speed as your processor's HTT/FSB while a 1T with fair timings is ideal, this is possible with really good 2x512 RAM (TCCD or BH-5 chips would be optimal). Currently 1GB sticks have to run at more relaxed timings and require a good memory controller on the CPU, at least Venice generation or better, due to the stress of handling all that data.

The real advantage of 2x1GB is the size allows for less use of the Page File in Windows, especially if you run many programs at the same time or a few programs with high demands, like Battlefield 2. Running multiple programs on a dual core system would necessitate more RAM.

To sum up:

If you plan on running lots of programs at the same time, or play BF2, go with 2x1GB. Your Opteron's memory controller should be able to handle that at 1T Command Rate.

If you go with 2x1GB, chances are that tight timings are out of the question. Go with a kit rated for higher speeds (500MHz instead of the standard 400MHz) at 1T Command Rate. If the kit can stay 1:1 with your CPU overclock that would be better.

If you don't plan on running lots of programs at the same time, or play lots of BF2, go with some really good 2x512MB ram, like OCZ Platinum. Try to keep the ram 1:1 with your CPU overclock and the timings tight.

DO NOT GET SUCKERED INTO TAKING 2T COMMAND RATE!
