Glad you figured it out.

I tested two sticks of Micron PC100-222-620 128mb that arrived today for a socket 7 board with a FSB of 83mhz. This ram is 2 sided and ECC where the ram in the benchmark is 1 sided and non-ECC . I am getting 232mb/s with the new ram. Almost 10% difference due to being ECC.

Have a good day.

AFAIK it's normal for ECC Ram to be slightly slower.... if... the ECC is also activated in the BIOS.
Otherwise, I presume it should be the same as normal Ram.

In my case, there was no difference in SpeedSys between a single-sided and a dual-sided module of the same size & speed.

Today, I also installed a K6/2+ @550 on this board; and compared with a picture of SpeedSys that I have of the first board with a K6/2+ @550.
And except for the CPU score being a few points slower (on this board); all other numbers are virtually the same.

I will try to continue some RAM experimenting & benchmarking in Windows; as I have installed George's Memory Interleave Enabler for VIA Chipsets (https://www.georgebreese.com/net/software/) on the previous board, and the RAM speed was noticeably higher.
But I never got around to testing single-module vs multi-modules. Or single-sided vs dual-sided.
