EDO SIMM Longevity at 100 Mhz

I am putting together a K6-2-500 system from parts for a charity and the best memory I can come up with is 2x64MB Edo (double sided w/ 4 chips per side). The bus is set at 100 Mhz for this board, a jetway 542b, and it does have a number of other settings, maybe 92, 83, 75, 66 (hard to read). The board runs well with the no name memory now, but I am wondering if I should clock down the system to 83 and use a 5.5 multiplier (max) to ensure it runs ok longterm. Any ideas would be appreciated.

If it runs ok now, I don't think it will suddenly fail in the future. I've run EDO at 83 MHz for years with no problems. You could run memtest86 for a while to see if any problems come up.

If you really feel nervous about it, you could always run it a 6x83=500. Set the board multiplier at 2x, and the K6-2 will read it as 6x. It will lose a little performance, but not too serious.
