@RolloZ170 Can you explain why the A0 stepping from the 8222L(QLPA) is bad? Got one for 19 bucks and arrives in a few days.
intel dropped 2019 support for cpuid 50655 stepping A0 microcode, is runs still under PRD but its not.@RolloZ170 Can you explain why the A0 stepping from the 8222L(QLPA) is bad? Got one for 19 bucks and arrives in a few days.
Agree with that, and its exactly what I am interested in, where does that edge lie? I don't want to assume just buying the 8k$ original part is the only option without trying to prove the opposite is true. We need more ram than a consumer CPU can give us although we currently run some Ryzen 3950's for parts that need high single thread performance.I assume you know what you are doing but your requirements seems contradicting - stable work and easy BIOS updates are not going hand in hand with this type of CPUs. You can check the thread for multiple post of request of hacked BIOSes or if a CPU will work with particular board.
It looks like you will be using the CPUs for some kind of production. Also consider the longer term maintenance effort of such solution. Can you afford the down time if something goes wrong? Do you already have the servers?
You haven't mentioned your space and memory requirements, but have you considered consumer CPUs - Ryzen and current gent Intel can be got with 12-16/20 cores easily.
the seller writes OEM no ES but the screenshots show QS(ES)with the 8350C (QXC3) that seems like a nice chip, TDP well within chassis spec unlike the 8375C. So a setup with a C QS chip that is deemed supported by the chassis according to the Ebay resellers? How risky is that?
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.Thinking of buying H262-NO1 with the 8350C (QXC3) that seems like a nice chip
not realy: "these 'C' CPU are confidential SKU for select customers, ask the OEM you got them from for support"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
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.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.
official QS same microcode than production partsSo 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?
That seems like good news, I will purchase some for testing, are you interested in the results? I can post them once the hw is inofficial QS same microcode than production parts
unfortunaly Intel QS are same than production, not like AMD EPYC unlockedI will purchase some for testing, are you interested in the results? I can post them once the hw is in
Did you end up finding bios to support QL2K ?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.
there is no extra Workstation chipset. the difference is only the count of uplink lanes and IO ports.Can a W series QS LGA3647 Xeon working on a server motherboard? Or there is a limitation for workstation chipset only?
had a Xeon W3245 QS working on X11SPM (with old BIOS 3.0 - still not TDP block there like from 3.4 and up)I have a Supermicro X11SPM-F with the latest bios (replaced microcode)
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)
X11SPM uses the same components than on X11DPi-N(T) (2x 205W)What do you think is the safe TDP for motherboard can handle? 205w?
will NOT work or just at 700mhz with additional problems you can not solve.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?
Thanks for the info!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.
