As I understand it, the AMD PCHes contain mostly a ROM and IO expander (hence why A300/X300/X600 exist), but the Intel ones do something or other important to the boot process and contain the Management Engine. Though GNR removes the requirement to have one.

What's the idle power like on the Graphcore cards?

Looks like it was that. It worked outside the case, and there is a standoff I missed. I guess it wasn't a problem until things moved while I was reinstalling the board and some soldermask got scraped off. I feel silly for not checking the standoffs properly. Thank you to everyone for the help.

I am using a Gigabyte MS03-CE0 motherboard with a Q30H (engineering sample) LGA4677 CPU. I was testing it outside of the case on a box because of some mechanical issues with a GPU, but after reinstalling it in the case, using any of the top DIMM slots (E0-H0) causes "bios : Uncorrectable ECC /...

I get fan spinups intermittently. If there's a minimum RPM, why would it complain seemingly randomly? Also, ipmitool lists 150 and 300 RPM as minimum thresholds for something or other, and the fans are apparently above that.

I figured it out, I think. On the "edit fan profile" screen: the "policy" dropdown lets you select a second configuration to be applied in some conditions. It seems like it was switching to that second configuration for unclear reasons, because when I set it to match policy 0, the spinups...

I have a similar issue with an MS03-CE0. Increasing the minimum fan speed seems to make it do this a lot less. I'm not sure why. Overly aggressive thermal protection?

Thanks! I have it "working" now, though the bracket for my NIC is taped on because I am too lazy to get my 3D printer to do the tricky parts correctly and I can't do the cabling properly yet because the CPU power connectors are in inconvenient places and I need to get some extension cables.

It's been annoying to source the parts, but I finally have everything for my build (Q30H/MS03-CE0, since I couldn't get a Q2SR or Q2SP for whatever reason). It should be ready in a few hours unless something goes terribly wrong. @RolloZ170 Can you send me the patched BIOS for it?

Based on the socket, this is an LGA 3647 platform (Skylake/Cascade Lake), with two memory channels not connected and lots of PCIe lanes not exposed. I wouldn't consider it very useful these days.

There are no longer listings on the UK eBay site for individual EMR ES CPUs, so I tried directly messaging the sellers who were offering them bundled with a motherboard in case they could do something. One said they didn't have any left and one said they had Q2JH available. I could use the US...

Has anyone heard of Q2JH? A seller says it's an "8592 ES" and that "Q2SR has a base clock speed of 1.7 GHz; Q2JH has a base clock speed of 2.0 GHz".

Two sellers I tried to buy a Q2SP from cancelled their orders and now their listings because of, allegedly, some issues at their warehouse. I suppose I am now in the market for a Q2SR (once I get confirmation that the board I ordered is shipping...).

Do the FlashSystem SSDs work on a non-IBM platform using standard NVMe?

I'd prefer a Q2SP, I think.

Ah. I expect the Q2SP to be good enough that I won't have to upgrade until I'm also ready to replace the platform. I heard that an EMR single-socket server would use 150W or so idling, which is okay. GNR would do sub-100W, but I'd be sacrificing too much core count.

9334 is Genoa. 9XX5 is Turin, which is already out. The last time I tried to look at Xianyu it required me to make an account, I spent ten minutes trying to reverse-engineer the captchas without being able to read Chinese, and then it rejected my phone number. I'd prefer to avoid this sort of...

I see. Thanks. 32 cores is workable, but I don't see any Q2Y7s on eBay and I would rather not deal with Chinese-language stores.

A Q2SP listing says "NOTE: Only Gigabyte dual-socket MS73 or MS33 motherboards are supported", so I guess I have to get Q2SR instead?

I thought Venice was supposed to get a new platform?
