IBM Netvista vs ECC memory

  • Thread starter Thread starter Kebeb

I can't find information about ECC memory support for IBM 6791-KAG
(ECC 133 SDRAM). (It's much cheaper
than pc133). There is nothing about it.
That's all I've got:

My chipset: http://www.intel.com/products/chipsets/845/index.htm

Maybe You may help me ?

Thank You in advance

This URL suggests that your only option is PC133 CL2 non-parity SDRAM
UDIMM:
http://www-307.ibm.com/pc/support/site.wss/MIGR-39330.html

In any case I would expect that the ECC/parity bits would be ignored
if the chipset/BIOS doesn't support it. Therefore I'd buy the
unbuffered ECC SDRAM. If it works, then good. If not, then try
snipping off the extra chip(s) with a pair of sidecutters, or cutting
the traces to the ECC/parity data pins.

See http://pinouts.ru/Memory/DimmSdram168Unbuf_pinout.shtml

BTW, AFAICT, an ECC DIMM is identical to a parity DIMM. It's the
chipset that defines the function.

One thing you could try is to buy the ECC/parity DIMM and test it with
Memtest86+. That may at least tell you whether ECC support exists in
the hardware and has been left out of the BIOS. If so, then there may
be a way to modify the appropriate chipset register(s) to enable ECC
support.

Here is a comparison table of the various 845 flavours:
http://compare.intel.com/pcc/showch...1618,1831,1832,1840&familyID=11&culture=en-US

Only the 845 and 845E chipsets are listed as supporting ECC.

The 845G, 845GL, 845GE, 845PE, and 845GV do not support ECC.
