Linux SMP ppd confusion

[Pilgrim57]

Hello fellow folders.
So I'm running via VMware & my ppd is dropping with new projects..
2604 or 5 gave 1760 points & took about 2 days.
I'm now getting, 2609 = 1523 credit 642 ppd takes 2 1/2 days.
Currently 2608 = 1385 credit 577ppd & will take almost 3 days.
It seems the latter 2 projects have a 4 day deadline compared to 3 for the 2604/5's.
What is really weird is that I reduced my o/c from 218 to 212MHz [x12] & the WU has speeded up a little Could this indicate a RAM prob? I have 2 x 512 @ 2-3-3-6

Also have 2x 512 geil slightly slacker at 4,4,4,8 (but is 667 at 860 ) so I probable not ram related unless your an avid gamer

As to the OC - i've always found that fsb that are divisable by 4 give best results, could just be that chip is more efficient at that rate

My RAM is DDR 3200LL Corsair with the LL standing for low latency. On my ASUS A8N SLi Premium it won't boot when I set it to 333MHz even if I set it to SPD rather than manual. I'm incline to blame the mobo as this memory ran at 333 & 400 on my old mobo [socket A].
