Mixing memory didn't drop benchmark much
On a 100MHz memory bus (AMD 751 chipset) mixing one PC133 and two PC66 (?) strips only dropped the benchmark 5% running SiSoft Sandra 2004. I'm not sure about these other 2 strips (32MB each) of memory.

I'm not sure about these other 2 strips (32MB each) of memory. The date on the chips is 1998. Can I assume it is PC66? I'm just surprised the hit was less than 5% vs. testing only the PC133 strip (128MB) by itself.
It went from 660MB/sec down to 630MB/sec when the additional strips were added.
Input? Am I correct about the '98 chips being PC66?

Probably not, but you can check that with sandra.
Go to Mainboard Information and scrool down to somethink like this
Memory Module(s)
Memory Module 1 : 128MB 16x(8Mx8) SDRAM PC133U-333-542 (CL3 upto 133MHz)
Memory Module 2 : AMD 128MB 16x(8Mx8) SDRAM PC133U-333-542 (CL3 upto 133MHz)
Memory Module 3 : 256MB 8x(32Mx8) SDRAM PC133U-333-542 (CL3 upto 133MHz)
you can see all the modules in my system are PC133.

I returned the box to the owner since it was up tp par. I was just wondering about the lack of a hit with the older memory.
I know since the bus isn't a 133 the difference wouldn't be that great, but was surprised to see the little difference.
Since there WAS a hit, is it ok to assume that the older memory isn't PC100? If it was PC100 there shouldn't be a 'hit' at all mixing it with the other stick (even though it was 'better' memory?
