@Klee, @Marsh Thanks to you both for the clarification. Having a look at the Intel ARK, it seems that there has never been a Xeon E5 CPU that gives you 2MB of L3 per thread, so you are always looking at having to disable cores - even on the newest V4 chips. I had a quick look at eBay and found several SuperMicro 4-node chassis with E5-2670s for sale, and then plugged the cost of the chassis into the calculator you linked, and the payback time was not encouraging. It looks like I will just have to be content with my 2khs for now.
Boddy, dont You mean in Victoria, Last time I looked and lived there, it was a small state with great coffee and food, but could hardly be called Australia....Here in Australia peak charges are $0.35 Kwh and they pay $0.06 Kwh for your excess. It's a rip off!
There is also a low end 4 0r 6 core Xeon without hyperthreading that has more cache than is optimal mining Monero.@JazzFaucet I disagree. I am writing this on E5 V3's with 8 cores/ 16 threads and 35MB L3 cache each.
The 1603/1607 are quad cores without hyper threading with 10mb cache and run at 2.8 and 3.1ghz respectivelyThere is also a low end 4 0r 6 core Xeon without hyperthreading that has more cache than is optimal mining Monero.
I don't remember which one tho.
Yea but by the time you end up spending money on a motherboard/ system and the power for fans it is less exciting to use this type of chip.The 1603/1607 are quad cores without hyper threading with 10mb cache and run at 2.8 and 3.1ghz respectively
Can anyone give me an idea of the expected hash rate on an Intel server with 2 E5-2670 V1 and 128GB DDR3 RAM? Also expected power consumption.Take a look at my Open Compute build.
Dedicated Crypto Mining Open Compute server build.
Final prices and setup and performance.
2x Wiwynn open compute server $380.00 NEW *
4x E5-2660 V1 cpu’s $207.92 (best price found but the seller only had 4) USED
4x E5-2660 V1 cpu’s $230.80 USED
8 Gb of DDR 8500 8x1 Gb sticks $17.50 USED
4x used hard drives that I already had $00.00 USED
1x New HP PDU $10.00 NEW*
2x Power cords to reach unused 250V a/c outlet $20.00 NEW
*not including shipping
Total $866.22 gives 3480 H/s
I did not include the prices of the video card or pci-e usb card that were installed to install Ubuntu Server 17.04, the video card was an old Dell oem nvidia that came out of a free pc, the usb card was borroed from my main pc.
To mine XMR that come out to about $1000.00 less than a dedicated 5 GPU rig using RX580 4 gig card with slightly higher performance.
I went with new open compute servers, you could save another $100.00 buy going with two used Quanta open computer servers, I hate buying used motherboards and was willing to spend a little more.
