I already have one too many computers, 1 x i7, 2 x Xeon 12 core and 2 x 14 core Xeons but I saw an 18 core E5-2696 going for peanuts on AliExpress so I bought one.
If I can be bothered, one of my 12 core Xeons is in a very good Gigabyte board so if I can find enough time (and room) I will swap the two CPUs and see what it runs like. I have sortof got used to the Xeons, they generally peak at 3.6 gig for low core usage and drop speed as more cores are used.
They are supposed to perform well on low core counts and for reasons that I don't understand, apparently higher throughput than the 12 and 14 core versions.

:thumbsup: We will see what can make that monster!

18 assembly missiles run simt :thumbsup:
Even harder to find uses for 18 cores than previos 14 cores

:biggrin:
Did not take all that long to do, pulled the 12 core and installed the 18 core and it started first time. The only quirk is the OS is not recognising one of the 16 gig SIMMS so I am only getting 48 gig instead of the 64 gig. CPUZ recognises the 64 gig and the BIOS does the same so its probably in need of a new Intel Xeon driver set.
Did some basic benchmarking and it is faster, both in single core and multicore. Wind it up and it runs at just under 3.6 gig, the 18 cores really hoot for multicore work but the important thing is it still runs at about 50c on all cores during the benchmark so cooling is not a problem.
Tried another set of Intel drivers but no difference but set the BIOS to optimised settings and its peaking at between 3.6 and 3.8 gig which is very good for a Xeon which are basically server chips.
As far as the memory modules, I will have to pull them one at a time and see if one is suspect.
I thought someone would see the humour of Core Temp displaying 18 cores.

This is the test I was after. I have not solved the memory problem yet but it does what I wanted an 18 core to do.
106 MP4 Video files 7.76 gigabytes
i7 6 core @ 4 gig
63 Minutes 8 Seconds
Xeon 18 Core @ 2.6 gig
41 Minutes 41 Seconds

Solved the memory issue in an unusual way, I had kept the leftover DDR4 modules that came out of my old monster and had 3 that I knew worked correctly. The Gigabyte board has 8 memory slots and there is a diagram of how and where you run 6 modules so I put 2 x 8 gig modules in the correct locations, turned it on and it started normally and displayed a full 64 gig of memory.
Ran the speed benchmarks again and it is up to full speed, slightly faster than earlier attempts and faster single core than the 12 core I replaced. Its not far off my old overclocked i7 that I use as a dev box so it will be a useful "grunter" doing mass multithread work. :biggrin:

One more test that I am very pleased with, I have just finished another video file for Youtube of 3.1 gig and to get its size down, I fed it through "ffmpeg" to reduce it down to 844 meg. Done on my old i7 dev box, it ran between 15 to 20 FPS. Just ran the test on the Xeon and it ran between 31 and 39 FPS which is just over twice as fast. :biggrin:

Perhaps you can make some UAPs effects.

Something we do have in my suburb is some really smart cats so they may not be at risk, even if someone around the area was so inclined.
Shame that X99 is in its twilight, they run AVX2 downwards just fine but Microsoft in their infinite wisdom ( :rofl: ) have shot Win11 in the foot by requiring extra security hardware like a TPM module that rules out most older CPUs.
No rush but a later CPU that is a lot faster may be on the horizon but probably not until they run at lower temperatures, anything that clocks at 90c and higher horrifies me, :thdn:

Interesting idea but these Xeons (v3 and v4) date from 2014-5 where the Xeons in the list are entirely different. You can start to get some of them second had but they are still expensive and little chance of getting a desktop board for them. I did see one but the price was prohibitive.

How many core count all computers together?
A modern beowulf made out of 100 cores possible, instead of big room full of 100 old computers?
In my experience lower temp cpu which is faster,my first laptop got hot and hardly ran hd movies from later my smartphone, which played it back easily while phone still keeps cold
