128 MB RAM appears as 64MB
HI,
I have just tried to upgrade a MS6178M motherboard from 64MB to 128MB or 196MB. using a PC133 128 MB Dimm. When I replaced the existing 64MB module with the 128MB module the BIOS comes up showing only 64MB. This is in either slot. Plugging the original 64MB in as well, and the BIOS come up with 128MB. Windows accepts whatever the BIOS gives it and works OK. The manual for this motherboard states that it can carry either 64MB or 128MB dimms for a maximum of 512MB, and then goes on to give details of how 2 x 64MB is actually handled - no further mention is made of 2 x 128MB. I have had a good look though the BIOS, both on the system and in the manual, but can see way of activating the full 128MB. Any ideas would be very welcome TIA Red --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

I seem to recall you have to install in pairs 2 x 64 (128) or 2 x 128 (256)
only and not a combination 1 x 64 and 1 x 128 will only give you 128 max dj "Red Kite" wrote in message ...

Your motherboard does not support the higher density chips on the 128 MB DIMM. I am guessing that it has 4 chips. If you get a 128 MB DIMM with 8 chips your motherboard should recognize it as 128 MB.

M60 (dj) and Mike,
Thanks for replying so quickly. I don't think this box has to have pairs of DIMMs, there is no mention in the manual, and it has run for 5 years on a single 64MB DIMM. I had not thought of 4 chip vs 8 chip DIMMs, that could be the reason. Since this upgrade is a favor for a friend, and I have effectively doubled their RAM, and got the system out of the bind it was in - I am inclined not to mess about with anymore chips - but appreciate the ideas you both gave me.

Sounds like you have high density RAM instead of low density.
How many ICs are on the 128MB one? "Red Kite" wrote in message ... HI, I have just tried to upgrade a MS6178M motherboard from 64MB to 128MB or 196MB. using a PC133 128 MB Dimm.

I recently did the same with my sister's PC. I had a 128 MB DIMM with 4 chips (PNY) that would not work at all in two other PCs. I put it in my sister's PC and it was recognized as 64 MB. I tried another 128 MB DIMM (9 chip ECC) and it recognized all 128 MB. I had other plans for the ECC memory so I left the PNY DIMM in her PC which doubled her memory.

Thanks to you all for your comments, I suspect the MoBo was just too old for
the RAM I was trying to feed it. My friend has gone away happy to get another 64MB on the machine, and out of trouble - So I'm leaving it at that. Thanks again Red "Pen" wrote in message ...
