Better ram for my overclock

[LeftyAce]

Hi all,

I recently got an Opteron 165 with the intention of overclocking it, and have had good results thus far. For testing purposes, I put my ram on a maximum divider, and found that the CPU was stable up to 290FSB at 1.4V (9x multiplier, so 2.61GHz). Prime95 ran small FFTs (which fit in the processor cache, so no ram access) for 9 hours w/o an issue.

Then I went to deal with my ram.
At stock speeds, I have to put my ram on a divider (running it at 183 instead of 200MHz) to get it stable.

I'm running 4 sticks of corsair value ram, and understood from glc and others that on the A64 platform, running ram on a slight divider was no big performance killer, so I might be able to survive with cheap-o ram.

As soon as I try to move my ram up from 1/2 FSB (running at 2T, 145Mhz) the computer won'e even boot windows. At the lowest ram speed, and loose timing, a prime95 'blend' test that actually uses RAM fails on one core after 15 minutes.

My question is, what ram makes sense as far as upgrading. To run the RAM close to 1:1 with my oc'd FSB, I need DDR500, but it's kind of expensive. Would a quality set of DDR 400 work almost as well?

What can you tell me about g.Skill? Such as this: http://www.newegg.com/Product/Produc...82E16820231047
Or this ocz? http://www.newegg.com/Product/Produc...82E16820146970

Much higher price than that and I can get a set of Mushkin Redline at DDR500: http://www.newegg.com/Product/Produc...82E16820146034

(You can buy the redline on Mushkin's site for $180).

Sorry for the long post. Looking forward to your thoughts!
