Thinking of buying H262-NO1 with the 8350C (QXC3) that seems like a nice chip
one more thinkg you should know anout 2nd/3rd gen 'C' SKUs. if you have any problems you can not ask Intel, or if you ask you will not get the answer you expect.

haha, yeah, the answer will be how the f did you get those give them back, but then in enterprise lawyer language and that sounds way more scary

I never really contacted intel for anything with regards to support, but yeah there is a risk indeed

not realy: "these 'C' CPU are confidential SKU for select customers, ask the OEM you got them from for support"
its mor like a OEM Windows, on any issues/problems ask the OEM, not MS.

Hey,

I have been playing around with the idea of buying QS cpu's for a while but it looks like the time has come now, i need 40 CPU's this year and saving a bit on each is just worth too much to ignore the QS option. I have a couple of options for machines, mostly looking at 2U 4 node machines like

H261-NO0 (3647)
H262-NO0 (4189)
X11DPT-B (3647)

I am looking for 20core+ CPU's, clock speed does not matter a lot and I prefer lower TDP/core cpu's with the lowest price per core, @RolloZ170 can you maybe recommend me a CPU for this? As far as i could find 4189 was still significantly more expensive and i cannot find a lot of information about QS compatibility on these.
My thought is if you have to ask, you shouldn't be deploying 20 nodes full of engineering samples. Being able to get support from the vendor is important and if you have a QS part in your server the system vendor will probably refuse to provide support.

Ice Lake Xeon is pretty reasonably priced. If you are not looking for top spec parts the Silver 4316 basically matches a flagship Broadwell CPU for $1000. A 2S 256GB node is going to be around $5000 so you're looking at $100K for 20 nodes

@RolloZ170

So I got some additional screenshots from the seller, it shows the cpu name in the bios, in windows, in cpu-z. However it does also say ES... so what are these?

Multiple sellers have now uploaded similar images with all saying this is production OEM and QS at the same time

Both of those are either impossible to find or crazy expensive.

EPC621D8A is my best bet, any idea how/where to get a modified bios? I don't trust the seller I got the chip from.
Did you end up finding bios to support QL2K ?

Finally got the board to post with my 8175M, looks like my QL2K is just dead, gives 53 memory not detected error. Oh well into the dead chip bin it goes.

Can a W series QS LGA3647 Xeon working on a server motherboard? Or there is a limitation for workstation chipset only?

I have a QL1L Xeon (6138ES) but i want to replace with something better for gaming because i no longer needed this system for work. I have a Supermicro X11SPM-F with the latest bios (replaced microcode)

There is an Intel Xeon W-3223 QS cpu ebay link
I know that is a low end workstation cpu for this socket but still better for gaming than the low clocked ES cpu.

The W series is not on the motherboard support list but the socket is the same, mobo supports 165w tdp and there was an Xeon Gold 5218R cpu for few weeks testing and worked in this motherboard so it tested with newer Cascade Lake (Refresh) core (with the stock new bios)
Thanks!

there is no extra Workstation chipset. the difference is only the count of uplink lanes and IO ports.
if you asked supermicro i.e. they most say its not supported because the extra 16 PCIe lanes are not used, Optane Memory is not supported by Xeon W but the motherboard can, and so on...

had a Xeon W3245 QS working on X11SPM (with old BIOS 3.0 - still not TDP block there like from 3.4 and up)

What do you think is the safe TDP for motherboard can handle? 205w?

I have a NH-U14S DX-3647 so the cpu cooling is ok but i dont want to cook the VRM.

X11SPM uses the same components than on X11DPi-N(T) (2x 205W)
there is overcurrent & overtemp function. for stable operation there is a continuous airflow required over the Heatsink like in a flat server chassis.

Can i use this in X11SPM motherboard? I know there is a fabric pcb on this F version cpu but can i simply cut it off?
will NOT work or just at 700mhz with additional problems you can not solve.
the omni path fabric needs additional voltage regulator which the most supermicro not have.

@RolloZ170 Thanks for all your help, it's nice to have expertise that is so accomating and available. I have been sitting on those 2 - X11DPL-i boards for a while now but finally decided to get a Xeon Gold 5218 ES2 QQ9M 125 tdp, I only purchased one just to be sure. I am very happy and will get the other 3 in the next few weeks...

Again thanks for your support and look forward to rocking those 2 rigs now in the Boinc.
PS: how is your mod rig X11DPL-i working out? keep on keeping on!

This is a great forum!
Respect

If you get tired of the egg carton (?), I can recommend the Streacom Open Benchtable. For ATX and EATX you will need more M3 standoff screws than is in the package. Version 2 also has two holes for a Power-On and Reset switch now. Switches are 12mm e.g. Excellway® LED Drucktaster Grün Druckknopf Taster Push Button 12mm Auto u.s.w | eBay. Green is nice and bright, yellow (right, in reset button, for HDD activity) not so much. No idea what LEDs are employed, at 3.4V some are bound to be rather dim. CPU is 8259CL on Asrock Rack board. Temperature of CPU package never goes above 65 degC even under highest loads. Fans are PWM and at idle at 700 rpm the entire assembly is inaudible. PSU is a 600W Seasonic SSR-600TL fanless. Right fan cools the Mellanox CX3, chipset and close side RAMs, CPU fans also cool RAM on far side through Bernoulli effect. I also found a funny air flow around the CPU VRM cooling fins. In the first half, air is flowing inward due to the same effect of close side CPU fan. But on the second half of the fins air blows outward, because direct air flow from the close side CPU fan is "visible".
