K7M Mainboard and SDRAM PC-133 ?

Hello there - and a happy new year, first :-)

I have a K7M motherboard in one of my PCs, equipped with an Athlon 500
and 2x 64MB PC-100 RAM.

One of the RAM chips produces errors, so I had to remove it.
As 100 RAMs are no longer available (except at eBay for prices much
to high, IMHO), I bought a 256 MB PC-133 RAM (after confirming in another
newsgroup, that 133 should run on a K7M).

It does not ... :-(
The boot process stops at the message "Checking NVRAM ..." and the
system freezes.

The 133 chip itself is free of errors, it is working at the moment in
the machine on which I write this message.

Has anybody any idea how to get the 133 work in the K7M?

Thank you,

Detlef

While this board can run PC133 SDRAM, not every PC133 SDRAM stick is
actually compatible with the chipset, for reasons very similar to those
with the i440BX. Thus, this document should be of some help:

This board does run PC133 (I'm in fact running the Crucial PC133 memory
in this board). This board is, however, very finicky when it comes to
memory. I had a nightmare getting it to run initially until I
subsituted Crucial memory for the noname memory I had picked up cheap at
COMPUSA.

I found, at the time -about four years ago, that if I tweaked the memory
settings in BIOS(essentially slow down the motherboard) I could get the
cheap memory to run. I don't remember which settings I played with at
the time, but when you go into BIOS switch off the SPD settings and set
memory settings manually. That might allow the PC-133 that you bought
to run on the board.

I had to do a google to jog my memory, couldn't even remember what I had
in my K7M except that it had a 500@800MHz. ;P

K7M v1.04 using 1007 BIOS.
CAS2 PC-100, 1-Kingston (128M?) and 2-PNY (64M?) sticks .

After building a Socket-A system I decided to update the BIOS to 1009 on
the K7M so I could get an old ATAPI CD to work in it, after the newer
bios the CD did work but the system wasn't 100% stable anymore and when
I would save BIOS settings (I tried every setting possible to make it
stable) I would have to turn off the PSU and back on again or it would
just sit there with a black screen.
