    Saw the Opteron 6128's are now $95 OBO on ebay. 8 Magny Cours Cores at 2GHz.

    Not the fastest, but you can pick two up and have access to 2P or 4P boards with 8 DIMM sockets per CPU (and they accept Registered ECC DIMMs). If you just want a machine with a lot of RAM these are pretty decent CPUs. I settled on these for my 2P Opteron 6128 system. 8x 4GB is a very inexpensive way to hit 32GB of RAM for ESXi.

    Not sure what they are accepting, but seem to have quite a few and at under $190 for two they might make a good deal.

    Here is a 4P G34 motherboard + chassis currently at around $700.

    I mentioned that chassis over at the DC forum at Hardocp. They noticed a few bent pins in one of the sockets.

    I see that first socket picture might be a bent pin, but not sure. Socket pictures are a bit tricky with lighting. Still less bent than one of the open box Newegg specials I fixed (very steady hand that evening.) Good potential warning though.

    They accepted my offer of $80 each. There are many more available, perhaps $70?

    Sweet! That is awesome. If you can get a deal on a 2P or 4P motherboard that makes a high-memory configuration very affordable.

    I picked up that four-slot G34 Supermicro 2042 on eBay. At $910 for the complete barebones server it was a deal - but not quite an incredible deal. It does match my existing 2042 which has its benefits when clustering. My data warehouse environment now stands at 116 cores, counting the 16-core (32 thread) machine that I'm testing!

    I used a zoom lens camera to look for bent pins. There are a few pins that appear "different" than others visually but under magnification they are just offset by a microscopic amount, not significantly bent. The machine boots just fine, but I'll be running a SiSoft burn-in to be sure.

    Awesome dba! In my experience, really bent pins = no post/ boot. I purchased two used G34 boards from Newegg with bent pins. Was able to re-bend back into place and even without being perfect, still ran Folding@Home for a few months on it without issues.

    A good amount of pins is used for power supply, so if one of those are bend you might be lucky and not notice anything different at all.

    It looks like I'm OK. The server spent the evening calculating pi to a rediculously large number of digits, using almost 100% CPU the entire time. No problems found.
