RDIMM's are generally cheaper as ECC UDIMM's are rare, and it doesn't 
matter what brands or w/e you use AFAIK - I have never had problems with 
mismatched ebay sticks.

If you want to play games on higher settings that can't utilize 16 cores 
you will have to get a better CPU, like a 6328, 6386SE or 6287SE. 
Something cool you can do with this too is play yours in a VM like me 
with an attached graphics card.
I would do a 6328 and a 6386SE combo with the first used for games.

If you want 1600mhz you need 63xx CPU's I believe.

Forgot to clarify, the per core/thread performance of the 6276 is too 
low for games that aren't highly multi-threaded so a better CPU might be 
a good idea for gaming.

According to AMD[1] and ASUS[2]  docs : [quote] DDR3 1600 can only be
supported with AMD Opteron™ 6300/6200 series processor [/quote]
so, I should be fine.

I didn't knew exactly what king of RAM to chose (CL, Voltage, Rank,
etc.) in order to have them running in quad channel, because those
recommended by ASUS here [3] are ether very expensive or unavailable.
But if you say that if I choose one of these [4] [5] it will work in
quad channel, then it's ok.

Thanks a lot!

BogDan.

1600mhz works with 62xx CPU's also.

Nope, I used two random pairs not on that list.
I haven't gotten a training error yet afaikand I have had this computer 
for almost a year.

Yeah I was too lazy to check, it is just 61xx that doesn't play nice 
with 1600mhz others.
