The best laid plans of mice and men
« on: February 28, 2022, 10:31:09 PM »
I thought someone may get a laugh out of this, A board I had been waiting on turned up today, a project of a different type, as this will probably be the last X99 box I build, I am striving for a low cost "ordinary" computer. The E5-2666v3 Xeon cost me $50 AU, the board landed at just under $150 AU and I own just about all of the rest. The only fancy bits I bought for it were 2 NVME Samsung drives, 1 at 500 gig, the other at 1tb.

Plonked it all together, installed Win10 64 bit on it and started to set it up. Somewhere along the line I lost the internet connection and wasted a couple of hours trying to diagnose it. Came back to my work box and it had the same problem, the router had dropped out so I rebooted it and all was well again.

The $50 buck Xeon is an interesting number, 10 core with a spec of 2.9 gig to 3.5 gig turbo mode, 40 PCIe lanes so it support a massive amount of bits, very large memory if you wanted to fund it, stick anything in the PCIe slots and it does not run out of puff. I had left over from my old box 7 x 8 gig 2400  DDR4 modules so I use 4 of them and it sems to work fine. Fortunately Xeon CPUs are not fussy about memory speed, they actually run at 2200 as 4 channel provides plenty of bandwidth.

I have a can ready for it that I already owned and the water cooler from my old box and I will have to have a rat around for hard disks, I have one spare 4tb Seqagate disk and about 5 old WD green 2tb disks a nd the only real limitation is the board only has 4 SATA3 ports so I will have to pick the best layout for the disks.

This is an updated set of X99 benchmarks.

                            CPU-Z Benchmarks
-----------------------------------------------------------------------------------------
PC      CPU        Cores    Single      Multi       Board                       CineBench
Name    Model      Count    Core        Core        Brand & Model               20
-----------------------------------------------------------------------------------------
Hutch   i7-5820k       6    445.0       3365.5      Gigabyte X99 GAMING 5       2711
Xeon    E5-2690v3     12    376.6       5192.0      Gigabyte X99 GAMING 5       4075
Haswell E5-2697v3     14    346.6       6048.1      Gigabyte X99-SLI            4514
X99     E5-2690v3     12    361.7       5113.9      Huananzhi X99 BD4           3936
2666v3  E5-2666v3     10    370.4       4490.0      Huananzhi X99 BD4           3514
-----------------------------------------------------------------------------------------

The minor speed difference between a Gigabyte board and Huananzhi with the same CPU, an E5-2690v3, appears to be the different chipset. The Gigabyte boards have an X99 chipset, the Huananzhi has a B85 chipset.

B85 earlier Chipset than x99?

This new one is up and running but the experiment flopped. I was interested to see if the Xeon 10 core E5-2666v3 would have a higher single core speed but it was no faster than the 12 core E5-2690v3 so I put the 12 core in. The 12 core was slightly faster on single core and a fair bit faster on multicore tasks.

I ran into something I had rarely seen, I had set it up on the bench with an old power supply and it worked fine. Put it into a box with an Antec power supply and it would not even boot. FF error on the board led so after doing the usual diagnostics, I tried the old power supply and it started immediately.

This thing is made from most of my leftovers, disks, memory and an ancient water cooler from my 6 year old dev box. Apart fom giving the radiator a good clean, it worked perfectly, even though its a single fan size. Yet another black ugly thing, at least this is a slightly smaller case. 2 NVME SSDs, 4 HDDs and one half gig SATA SSD.
