Any idea what hash rate these z400s in the newegg link in the OP get by themselves (I understand it'll be very low)? Also, would these z400s be solid for keeping wallets on as well as light internet use?
I am mining again on a Z400 with a single Vega 56 on Cast_XMR v0.9.2. The Vega 56 is averaging 1942 H/s.
http://www.gandalph3000.comThe CPU is a Xeon E5645 hex core processor with the AES instruction.

http://www.cpu-world.com/CPUs/Xeon/TYPE-Xeon%205600.htmlI am using XMR-Stak V2.3 and running it only on the CPU. I am running 1x threads on cores (2, 4, 6, 8 and 10). Core 0 is reserved for the Cast-XMR program. These settings use 10MB of the 12MB L3 cache. Again the last 2MB L3 is for Cast-XMR as I certainly don't want to throttle the Vega 56 just to get a few more hashes on the CPU.

The top of the line Xeon for the Z400 is the X5687 quad core and it will produce 230 - 250 H/s. I am running my main system, a Dell T5500, with dual Xeon X5687 processors. I am running 1x, 2x, 2x threads on each processor keeping core 0 free on both so that I can use the system while the miner runs full out. I am getting 460 H/s on it.
I will be adding in a second Vega 56 to this system tomorrow and will update the above results.

Well I did get the 2nd Vega 56 up and running about three days ago. With the Monero XMR hardfork the hashrates did drop slightly and now each Vega 56 gets 1900 H/s. Adding in the CPU hashrate of 188 give me a system hashrate of 3988 H/s.
