Testing 333MHz IBM 604ev 288in PGA module with G3 carrier for a PCI Mac

[obsolete]

Another four PPC604E3DBCG350E are on the way on donor CPU cards (IBM dual CPU 332MHz slot-module with 2x256k inline cache).
These are 58€ for one card = $28ppp for the cpu itself (desoldering and cleaning is easy)

I recently bought another 375 MHz rated 604e3 with ZIF carrier (from an RS6000 p43 system).
The processor version is 10,1 like the Apple Mach5 CPUs and is visually identical 604e3/375, i bought earlier, which is a 9,31 version.

The 10,1 version will identify as a 604ev while the 9,31 version will identify as a 604e. Both CPUs are nearly identical in terms of speed. The only difference is that i get about 10% higher scores in some floating point calculations with the 9,31 version. (no cache/Kansas board)

I have also found that the 10,1 version does not play nicely with older systems (TNT for example) while the 9,31 works without a problem. Maybe the 10,1 604ev has some changes to the default values in the registers or something. I could use a Mach5-card that i modified with a 9,31 604e3 with a TNT board if i had the Kansas Rom installed. The 10,1 604ev Mach5 card would not work in the older machines, even with the Kansas Rom.

@stynx I recently found a decent deal on a pair of the same IBM dual CPU cards with 350MHz 604ev chips, so I bought them to play around with:

Do you remember whether the CPUs you got from these cards were version 10,1 or 9,31? I hope mine are 9,31 so I can use them on Kansas CPU cards with a Kansas ROM in my 7600. All four of my CPUs are labeled identically on the heat spreader:
