Can't help you with (only one) 700 MHz SL49P without any heatsink I guess?

QAK9 should also work.

I am still looking for these CPU's. I've only managed to source 1 out of the 4 I need because I got lucky with a eBay listing, they unfortunately did not have more.

Update on this, now have 3 out of four 900MHz CPU's installed. If anybody has just one SL4XY they'd be willing to part ways with I'd be willing to pay a pretty penny for it. It would complete the CPU side of my SGI 540 Visual Workstation.

Endgame of what I'm aiming for:
- 4x 900MHz Pentium III Xeons (Currently 3/4)
- 2GB Proprietary SGI SDRAM (Accomplished)
- Sound Blaster Live! 5.1 Platinum (Can transplant from other machines)
- Some graphics card that works with the weird firmware of the SGI 540 (currently testing options)
- SD1100 Serial Digital Video Interface Card (One sold on eBay recently that I missed, I have a feeling I will be waiting a long time before I see another)
- Blu-ray optical drive with sata to IDE converter
- Internal Superdisk drive (saw some external SGI Superdisk drives on eBay that could be a good source for a internal drive colored black)
- SATA Raid controller (Finding something that is bootable will likely be extremely hard if not impossible so I might be stuck with SCSI / IDE)
- If the SATA Raid controller works out I want two SSD's in RAID0 for the system
- SGI Gigabit Ethernet Card
- SGI 1600SW or SGI CRT Monitor
- Accompanying USB SGI Keyboard and Mouse

Same problem here: I own 5 of the 2.8V 900MHz 2MB CPUs, but need a fourth sixth one to complete a HP Netserver currently running 6x 700 MHz 1MB.
I did not find a single affordable one during the last 10 years.

Well if you ever want to part ways with one of the 900MHz 2.8v PIII Xeon's I'm able to do $250 since I really really want to finish my SGI 540's CPU's.

I haven't seen a positive hit on my ePay searches in YEARS.

I have four of them, but I want to build them into a Supermicro S2QR6 build. (I need a chassis for it)

Hells bells, i'm having trouble getting P-PRO OD chips for my 6x6 without spending $500 a chip.

I will go through my box of processors and check if I have a stray 900/100/2m/2.8 cpu.

I remember reading that the SL4XY has a problem before production week 14 2000. Random freezes on CPU load. Anyone more about it?
Im trying to find the site again. Was from IBM a recall.

First I've heard about it.

I know my chips are good, I ran them for years as a home router. 😀

Id be interested to see what you find.
