I apologize in advance for another IBM question

[FDIV]

Here is the scenario. I had the best scrap yard day of my life. I came home with some 40 processors not the lease of which was a pentium 66 sx754 However, I found some more IBM processors which I can't identify. Here is what I know about them. They were in cartridges which plugged into large upright server (which I never saw.) These cartridges were about 2 foot by one foot by 5 inches. None of the numbering on the cartridges matched from one to another. Their were three that contained processors. Four processors each surrounded with copious amounts of cache. Both processors and cache were passively cooled. The way the cartridges were ventilated though I'd bet good money large fans in the server directed air through the cartridges and cooled the processors and cache that way. Each heat sink on the processors was marked 90H6364. You can see in the picture all the numbers on the processor. I have pictured the bottom, top, and under the heat spreader on one I broke trying to get it free. The pins are like extended solder balls. They are not made of solder though as they do not melt easily which made the processors very difficult to desolder. These processors are that extra thick white ceramic IBM used on its enterprise level servers. Any information you can provide as to the identity of the processors would be appreciated. Also, does anyone know anything about this difficult to melt solder? Below is a picture of an unknown LSI processor as well. I have no idea what it came out of but it is pretty cool looking. Stay posted for my new trade list. After this day at the scrap yard it should blow your socks off. It does include some of these unknown IBM's as well as one of these LSI's as well.

Thanks,
Les

POWERs, possibly POWER3, POWER2, and POWER3-II, but can be RS64, which is almost identical- it's easiest when you get the partnumber from sticker on PCB/metal case, then it's just few mouse clicks away to tell you.
check this one out: http://www.cpu-world.com/forum/viewtopic.php?t=5987

The LSI is quad geometry engine chip (MCM, 4 cores on single chip) from GU1-EXtreme (the last of the Mohicans) boardset (it has two of'em, I'm beating the crap of myself for not keeping mine)

Thank you for your help. I will look again for stickers on the board pieces the next time I get to the scrap yard. I hid one of the boards where it would not easily get ground up so It will probably be around when I get back there.

thanks,
Les

I have an IBM 20L8868 and it`s a RS64-II @ 340MHz!
Your chip looks like a RS64-II!
