Next Xeon arrived today
« on: December 07, 2021, 11:44:15 AM »
I had to chuckle when I saw just how big this Xeon E5-2697 v3 actually was. Its the same socket 2011-3 and it will fit in the hole but its the biggest Xeon I have seen in the v3 family. The specs look interesting, looks like I will have to get a different BIOS to test it out but in multi-core terms it looks like it has some legs over the E5-2690 v3 versions I have used so far.

Swapped the original i7 5820k and it was entirely painless, pulled the water cooler head, swapped the two CPUs, put it back together and it started and ran correctly. Runs at about the same temperature as the 12 core Xeon at 50c when thrashed, single core is slightly faster and the 14 core result in Cinebench is faster as expected.

Ran it on a video test piece, a number of MP4 files, and its about a minute faster again that the 12 core Xeon.

Have most of the old box set up with the Xeon E5-2697 v3 and started processing video which is usually a compression task on finished MP4 videos and I am really pleased with the results. Its usually one of those slow processes where you go and make a cup of coffee, make lunch or something similar but 14 cores running at an average of 2.9 gig really rips through video compression, on a recent 1080 video, it ran at a frame rate of about 180 fps and on a 4k video at a 32k bitrate it was still running at about 30 fps.

TDP was averaging 75 watts when the it was running at close to 100% each thread and the temperature rose to about 45c, given that it has a 3 fan radiator set up with fans in push - pull configuration. Seems to do ordinary stuff OK, browsing, video and its even reasonably snappy doing normal development work so all up I am really pleased with it.

 :biggrin: Hi Hutch,

You infected me with xeons! I also ordered one of them, Intel® Xeon® Platinum 8176 Processor (https://shop.immel.de/images/product_images/original_images/38057656.jpg), 38.5M Cache, 2.10 GHz https://ark.intel.com/content/www/us/en/ark/products/120508/intel-xeon-platinum-8176-processor-38-5m-cache-2-10-ghz.html

But unfortunately mine is an engineering prototype, therefore, the frequency is limited to 1.8 Ghz, it is not so critical for 150 euros  :tongue:

What do you think about the video, "Why you shouldn't water cool your PC" - https://www.youtube.com/watch?v=23vjWtUpItk

Hi LiaoMi,

I am starting to see Xeon Platinums coming onto the market and they look like they will deliver very good bang for your buck if you can find a decent desktop board for them. The 3.8 gig maximum turbo mode is what you will be looking at if you use the right cooling solution. You get used to CPUs that idle at a much lower frequency than their maximum turbo boost speed.

LATER : The engineering sample may not run the maximum turbo rate, I looked up the Intel site for that CPU but it would have been the release version.

If you can get all of the bits you need, it should end up a very powerful computer. Its also late enough to use AVX512 instructions and as Xeons are not all that fussy about memory speed, DDR4 @ 2666 is relatively easy to get.

Let us know how it develops, in my case I have no real need yet as I am using the E5 26??v3 series Xeons but in the future I could be tempted to go for one of these later Xeons as there is massive processing power available.

With the liquid cooling question, I also watch some of this guys videos but I trust my own practice more so. Best for best a decent liquid cooler will outperform the best of air coolers. I have used a massive "Satan" air cooler that was so big, I did not own a can that I could put the side cover on with it. It worked OK but one of my tests is the recovery rate after the load has stopped and a liquid cooler is clearly the winner here.

While the absolute limit is the die to can junction, a large copper based water pump and a 2 or 3 fan radiator will pull the heat out of big CPUs better than an air cooler. If your cooling and ventilation is good enough, you don't "fry" the board either and this makes them last a lot longer.

Hi Hutch,

I am not a fan of large dimensions when it comes to computer cases. For water cooling, you need a huge case like yours. I agree with everything you said, in my case, I compared

Dynatron L13 Intel Socket FCLGA3647 4U https://www.ebay.co.uk/itm/254941294369
vs
Noctua NH-D9 DX-3647 4U - https://noctua.at/de/nh-d9-dx-3647-4u
There is practically no difference in cooling, means that good cooling is a dominance over thermal conditions :rolleyes:

I think that this cooling will not be enough for maximum performance, other options are made only for server blocks https://www.ebay.co.uk/itm/223145955437?epid=27023795769, Asetek Launches 690LX-PN Cooler for Xeon W-3175X: Up to 500 W would fit well - https://www.anandtech.com/show/13920/asetek-launches-690lxpn-cooler-for-xeon-w3175x-up-to-500-w, but the price 400$ for this cooling is higher than the price for the whole computer  :biggrin: ("na ja für 3000$ CPU kann man auch 400$ aio Kühlung kaufen, aber ganz ehrlich für 400 kriegt man ein ganzes Kühlschrank")  :tongue:

There are other options:

EK-Annihilator Pro - 200$ -
EK-MLC Phoenix 360 Radiator Core Module - 300$ - https://www.ekwb.com/shop/ek-mlc-phoenix-360-radiator-core-module

https://www.youtube.com/watch?v=N29jTOjBZrw&t=215s:biggrin: :biggrin: :biggrin: :biggrin:

or

The most optimal option, but this product "EK-MLC Phoenix 240" is no longer available on the market.
EK-Annihilator Pro - 200$
EK-MLC Phoenix 240 - 200$

I am into midi towers because they are stuffed full of bits but unless you are filling a box with 5 or 6 HDDs, multiple SATA SSDs and a couple of NVMe drives, you don't need a big case.

I have seen enough cases that are a lot smaller, main boot off an NVMe drive mounted on the board, perhaps SATA SSDs and a BIG HDD for junk storage. I doubt you will get a small form factor board for that CPU so the case will have to be big enough to take the board.

Have a look at this guy, "Optimum Tech" on Youtube, he is often into exotic stuff but small builds seem to be something he has done. You should be able to get a 2 x 120 mm radiator for the top of a compact can.
