Thanks. The higher core count over E3 would certainly be helpful for VMs, and the lower clock isn't much of an issue for what I'd be needing.
Thanks for the low end figures. I knew there would be extra power draw, but its not as bad as I'd thought it might be. I also thought the SAS controller would draw more based on its specs.
Yes. E5-46xx chips are compatible with both Single, Dual boards.
Just ordered one. I try to use only Supermicro SNK's on Supermicro boards. They're quiet and cooling is excellent.
The product page for this motherboard only list SNK's for 1u and 2u. For my application a 4u is perfect.
L chips draw the same on idle as their non-L counterparts. Their draw is capped on the max for use cases with lower TDP chassis.
Yes to both.
about 6-8 months back, picked up few retail E5-4667v3 ( $80 each ) from ebay BO
I mention it in another thread, another forum member t-minus pickup few CPU also.
I was assuming that, like most Intel of that generation, E5s with common/similar base silicon will idle about the same regardless of TDP? So, guessing @Marsh 's E5-46xx numbers probably applied to mid-range 26xx as well?
If so, seems like the penalty over E3 is ~15 watts to have a lot more cores/lanes and power when I want them. I just know with my typical usage the system will be at idle the vast majority of the time, so for me a high TDP is less important when I figure heat/operating cost.
And now that the DDR4 ECC Reg has come down to earth somewhat, i think it makes sense to go E5 route and have extra CPU power available if needed especially if the delta in the total cost is minimal.
I've already got the RAM to go either direction, its just a matter of deciding. Too many options!
Is my math right one this?
15 watts times 24 hours/day times 30 days, or 10,800 watt hours (10.8 KWH) in 30 days.
Which you can just multiply that by your cost per KWH.
For me that's 29.6 cents x 10.8 = $2.96 per month, which is basically nothing to get a better system
I don't think the SAS controller adds a lot, but you are right about SAS drives, and the fans, that can consume a LOT.
Yes, that. For me, the cost of power isn't the issue. More important to me, Wattage=Heat. Heat=Fans and....well... heat.
Spouse approval is 100% the most important thing here....just ask her
. To maintain that, I've got all my equipment in my home office (AKA the guest room) and nothing is more than 8 or so feet from my head. I'm in north/central California, and the office gets sun most of the day, so heat is always an issue. I don't want fans screaming all day either, so most of the gear is only on when I'm using it. The exceptions are the switch and Unraid box, which I'm eyeing this board as an upgrade for. Those bring themselves up in the morning and shut themselves off at night. I've only got SATA drives in the Unraid server, and by its nature, Unraid spins data & parity drives down when not in use, so the only drives up all the time will be 4-6 cache SSDs caching writes and storing VMs.
Thanks to all for the info. Thanks to @jcl333 for posting the deal! Sorry to have drawn this off the topic of the deal itself. I'll stop now

The included guide should work fine.
Edit: Newer firmware on the Broadcom site. Instructions are in the package there as well.

Hmm. I think I'm going to bite on this. They sent me a "special offer" at $179, but I'm thinking of waiting till Monday to respond. I don't know if Ocean Tech is connected to the other resellers in Eden Prairie (Core 4, Rhino and who knows else)? But I've always gotten "the stingy" staffer on the weekends for Core 4 and Rhino, who are unwilling to deal or compromise on counteroffers.
Thats definitely not the lowest they've gone, then again maybe they hit a threshold where they can be choosier on prices now.
I got mine Thursday for $125, should arrive mon/tues, we'll see if I got one from the bottom of the stack for that price though.
