Xeon 8259CL

Confirming what Rollo said- spoke (Via email) to the Infineon helpdesk folks today. DON’T buy the USB005 (like I did).
quoting:
USB005 works with all GUIs except PowerCode. PowerCode is the only software you can use to communicate with PXE1610C.

I asked them where I could get the part @RolloZ170 noted above, since all the retailers are out of stock… they told me that if I had an FAE (Field Application Enfineer), I could have them order me one… the image they shared with me showed the low, low price of only 4,347 Euros, $4871.70, or 521640 Japanese Yen….(And unless I misread, you have to order 5 at that price… such a deal!) I replied with a screenshot of the Digikey price and told him that While I appreciated that they were available (at 70x the retail price), I was going to put my project on hold.

Honestly? They were super helpful and confirmed what I needed confirmed (Since I had not seen @RolloZ170 ’s post at that point.

SO… anyone near Houston have one they can loan me, or willing to let me leave a “deposit” with them for?

*Or* are there any other solutions out there to edit the controler values?

I appreciate all the knowledge shared in the posts above- it’s opened my eyes to i2c, and a whole host of system management things I had never even considered!!!

I have a X11DPG-QT board and was about to pull the trigger on a pair of 8259CL CPUs. Looks like the board supports up to 205W and the CPUs are 210W. So is this a no go combo?

that 210W is not the issue. the BIOS of the X11DPG-QTdoes not have a TDP block, there is a TDC block before any x86 code is executed.
you need the VRM modified to ICC_MAC=255A.

Do not buy from US West Coast... also do not buy without having seen both CPUs to be sent from front and back side. Look for dinged or curly (straightened) corners, ripped off capacitors etc. very very very closely. Other than that, good CPU. Turbos well (edit: i.e. make sure to cool VRM MOSFETs properly), a late-stage Skylake with many important bugfixes, core count well aligned with number of RAM channels, good instruction set, on-chip error reporting that actually works. I have three.

LOL. I heard many horror stories about them, I was looking at a Chinese seller.

I havent read through things 100% yet, but is the VRM mod a reprogram or a hardware mod? Or is it just simpler to send it to Supermicro to have the update done?

I was also looking at a set of Platinum 8222l QS. They are rated at 200W, where the X11DPG-QT can handle 205W. Getting 50/50 response if they are good or not.

VRM reprogram

8222L QS & 8222CL have TDC=255A. needs VRM reprogram.
there are two 8222L QS, stepping A0(50655) and B0(50656)
microcode for A0 ist not supported by Intel since 2019, take B0 if you can.
