Mainboards for Intel Xeon E5-2600 V4?

[nbritton]

Can anyone recommend a hackintosh mainboard for the Intel Xeon E5-2600 V4? Preferably dual socket?

Asus z10pe-d16 ws, just be aware of macOS max core count of 64 -> 16cores/32threads per socket.

Thanks for your reply, I didn't realize MacOS had a core count limit.

 

I'm not sure what I should do, I pulled eight Intel Xeon E5-2600 V4 engineering samples out of the trash the other day, four are E5-2680 V4 and four are E5-2660 V4. What should I do with all these? I already have a Mac Pro 2012 with two X5690, 128GB of RAM, Nvidia GTX 980, and PCIe SSD, and to be complete honest it's already fast enough and the system just works. A dual socket E5-2680 V4 would totally blow the socks off my Mac Pro 2012, but is it worth the effort of going the hackintosh route? Alternatively, I was thinking maybe I could build them into single socket gaming systems and sell them on eBay. What would you do with them?

 

Also is the MSI X99A Gaming Pro Carbon hackintosh compatible?

Those 2660v4 aren't really attractive, at all. I'd try to sell those on eBay.  Even the 2680v4s might be {censored}, if the uncore multiplier is capped to 16, which it probably is. I'd check that before throwing money on a mobo & ram. Overall, I'd try to sell them all, as is, and spend the money on a pair of OEM/QS v4s, mobo and ram.

I'm not sure what uncore is, but I believe the 2680v4 is unlocked since I can change the base frequency and multiplier. The chip is marked QHVA, and currently I have it working with a MSI X99A Gaming Pro Carbon, tested with BIOS V1.2 and V1.3.

The "unlocked" refers to the core multiplier lock bit not being set, allowing you to only under clock on E5 2600 v1/v2/v3/v4 Xeons. Setting any higher multipliers, than the cpu is rated for, will simply do the max rated multi. The only setting, that actually does something, is the BCLK and it'll max out at around < 110MHz. The gain from overclocking via BCLK is, in fact, near zero because of the "on die" voltage regulators current limiter -> the cpu will start to throttle. 

 

The crippled uncore frequency adds latency (40% x16 vs x27), not only to the L3 cache but to the memory controller, QPI, SA -> PCIe and so on.  It'll cascade on a dual socket system, giving you a really unresponsive system.

What do you mean crippled? A single 2680v4 is faster than my dual X5690 Mac Pro. However, I logged my system load on my Mac Pro over the last day and I only averaged 1.775 (uptime command, 15 minute average, n = 44, x̅ = 1.775, s = 0.7631), max was under 4 for a normal workload. RAM usage ranges from 50GB to 100GB. So since my workload can't max out even a single X5690 I'm doubting that upgrading to dual 2680v4 would yield practical gains relative to what I have now.
