Seller offered it ($200) so figured I could test it out, worst case I'll swap it to one of the gigabyte servers. I assume there will be some trial and error to get any HP working. Thanks for helping me tho.

Thanks, good to know. It's a big thread, I did see that supermicro is no good for ES parts, but I guess I missed the comments on Tyan.

What about the ASRock Rack SPC741D8-2L2T or GIGABYTE MS03-CE0? I'm trying to find something relatively economical that has lots of usable PCIe x16 slots, and I don't really need more than one CPU. MS33-AR0 is not very interesting because half the slots are blocked by the RAM. MS73-HB1 I guess might be a decent option, but I don't really need two CPUs and with only one CPU installed presumably some of the PCIe slots will not be usable. I suppose ASRock Rack SPC741D16X-2T might also be an option worth considering, similar setup as the MS73-HB1.

ASRock C741 series supports ONLY E-Stepping ES/QS/PRD processors, same than supermicro/Tyan.
(maybe the BIOS of ASRockRack/Tyan can be modded,)
Currently ALL Gigabyte C741 boards support D0 stepping SPR-SP ES. if you update BIOS, don't update Intel ME.

Got it. Are there any options other than gigabyte that are worth considering? Or is that the only option at the moment that doesn't involve modding the BIOS?

Also, is there a summary/compilation of this sort of information somewhere?

Hello everyone, I just bought an ASRock EPC621D8A from ebay. I also bought a 8251 QS (QPLC). I put it in my motherboard and plug in my psu and the leds turn on but the computer will not start when I press the power button. Did I mess up and pick the wrong CPU? I also bought two more: QPKD and QMQ9. If it is my CPU that is faulty or incompatible, do you think those two QS CPUs would be fine? Thanks in advance
