FYI - I tried a few different PSUs and they all exhibited the whine. It seems like there is some sort of communication (or lack of) between the chassis and PSU which raises the PSU fan speed. I would fear that higher wattage PSUs have higher performance fans which would be louder.

I think I’m going to lean towards the 24 core regardless. Thanks. I appreciate the help. Out of curiosity where do you get the information to look up the Q spec numbers? I can't find anything on QX7K anywhere.

So the seller is saying that the 20c version is “QS1” and won’t work in supermicro boards. The 24c is “QS2” and is almost the same as retail and will work. That seems to go against the pictures with the 20c version CPUz not showing it being an ES chip, but the 24c does show ES. 20c is QK7K (no...

Oh gotcha. So then it doesn’t make sense that it would have two fewer cores but still identify as a 3345.

Yes. It’s listed as a QS. There seems to be a trend where the 20c is listed as QS1/QX7K and the 24 is QS2.

Interesting. I guess this makes sense then if they did the same thing with the w-3000 series QS.

I’ve reached out to the seller to ask. I wonder if this is the result of a market strategy change? Maybe originally the 3345 was supposed to be 20c with 3.2ghz base but was changed at the last minute to 24? Maybe these are those super early units? I can’t think of any other reason both models...

Does anyone know the difference between these two CPUs? Both are listed as Xeon W-3345 QS. Both show the same S-spec (SRKSU). There’s are 20 core and 24 core models listed. Officially, the 3345 is 24 core. I can’t find mention of a 20 core version anywhere, but on some of the 20 core listings...

Wow. I bought two just before posting and there were 16 sold/more than 10 available still.

Looks like a decent deal for a relatively recent PCIe 4.0 drive. Just be aware that this is a 22110 m.2. Micron 7450 PRO 1.92 TB NVME SSD (MTFDKBG1T9TFR) 649528924698 | eBay Riley

Yeah, I got the Arduino fully working and it works very well - except for the PSU fan. It’s not overly loud, just whiny. I’ll try and grab some pics.

One of the interesting things is that I noticed the PSU fans always seem to be loud, but it does ramp up/down with temperature. They're the same PSU as a DL360/380 server and when utilized in that manner they're quiet. So, something in the shelf is controlling the PSU fan speed.

Depending on your risk tolerance and hardware capabilities you can pool multiple SLOGs, which will increase bandwidth. I've done this before with the old Sun F40s (4 x 48GB MLC) and NVDIMMs. Worked as expected. Riley

Good price for SAS flash. Couple things to keep in mind: 1) I think these were affected by the 32k hour bug. If these aren't already bricked then one would need access to the latest firmware, and the ability to load it. 2) They came from an EMC SAN, so they're probably formatted 520 byte...

If you have the hardware and are committed then the Nutanix community edition is very compelling. I ran it in a homelab for a couple years and it was rock-stable.
