I'm going to be buying a AMD Opteron 144 Socket 939 CAB2E tomorrow, now it says (with screenshot proof) that it can hit 2.9GHz (2906.3MHz) @ 1.520 vcore on 323 HTTx9.0, but im not sure if this was done on air or with water cooling (im probably assuming the latter). Now assuming i have the best air cooling i can possibly get (any suggestions welcome ) with my current GeIL value DDR Ram @ 2.5-3-3-6 PC3200, could anyone give me a rought estimate of what speeds i could expect (my new motherboard is a Socket 939 DFI Lanparty Ultra-D nF3 & i'm also going to replace the chipset cooler with my newSwiftech MCX159-CU heatsink)?? also is this cpu compatible? nvidia site lists that it isnt unless its a nforce3 professional but a post on dfi street says he used an opteron 148 on his nforce dfi ultra-d. if it isnt then please disregard this topic Thanks in advance to any help and estimates you can provide
