Welcome Ian,

Do both sticks work correctly and pass testing with, say, Memtest86+ if used individually?

Are these AMD64? I believe that early ODMCs on dual-channel Athlon-64/Opteron CPUs sometimes had difficulties when two unmatched DDR dimms of different capacities and/or timings were paired. The Rev E CPUs are supposed to have solved most of these issues (at least, I was able to use DDR400 paired with DDR 333 with my Rev E Athlon-64, but it dropped back to 333 on both DIMMs).

The fact that the machine will not boot up with that single memory stick installed suggests either a fault with the stick itself, or a compatibility issue of some kind.

When you say it doesn't boot - do you mean that the screen simply stays dark/powered off, and the motherboard gives you a memory error code (whether beeps or C1 port 80)? Or something else?

What you could also try to do would be to clear the CMOS NVRAM, by removing the battery for a minute or so, or moving the appropriate jumper to the "clear cmos" position.

ive put the 1gb ram in the first slot and 512 in second had a look in bios

advanced chipset features
dram timing settings
cas#latency 3 clocks
ras#precharge 3 clocks
ras# to cas# delay 3 clocks
precharge delay 8 clocks
burst length 8
agp aperture size 64mb

freqency voltage control
dynamic overclocking disabled

anyone know what to change to try make it work
screen just stays black to last question

http://www.memoryx.net/miin84nemmom.html this is my motherboard and 1gb pc3200 ddr400 non ecc 2.5v it should be compatable neo v 848p

Re: ms-6788 848p neo v ram prob

So hang on, you're saying that with both sticks installed the machine does in fact boot up, or at least POST...

Then what's the problem, as in, where does it actually go wrong? Does it only successfully POST sometimes, or hang while the OS is loading, or give you a particular blue screen?

If you can get so far as to boot from a CD, try running Memtest86+, last version is 1.65. You can download it from http://www.memtest.org

ive got a 512 in my pc that works fine i got pc booster that tells me 512ram i wanted to upgrade so i looked for a 1gb one compatable found this one got it put it in still said 512mb swoped 512 out of slot one with 1gb in slot 2 still no joy put 1gb in slot 1 on its own did not boot black screen no beeps
put 1gb in and looked in bios
advanced chipset features

read about dram timing settings but dont know what to change in bios to try

Nobody else seems to be answering so I'll try:

What does the part that you wrote, that I highlighted (in bold) mean? I really want to help you here - it's just that I don't get what you're trying to say.

If, with the 1G stick it does *not*, in either slot, POST - but leaves you with a black screen and no beeps, then there is *no way* you can access the bios/cmos setup screen, right?

If, additionally, you cannot POST with that one 1G DIMM, when your DRAM settings are set to the default 3-3-3-8, then generally, there is a problem. Either a compatibility issue between MB and DIMM, or a fault in the DIMM itself.


I suggest you try this:

1. Install your known good stick of RAM (512M) and nothing else. Then, in a safe manner, flash your MB's BIOS to the latest release from MSI. Sometimes BIOS updates resolve mysterious "hardware" issues.

2. Once that's done, power down, and clear your CMOS (nvRAM).

3. Then remove the 512M DIMM, and install the 1G DIMM first in one slot - and try to start up the machine. Failing this, try the 1G DIMM in the other slot. I'm assuming your MB has two slots, right?

4. If the system simply won't post, and acts dead with the 1G DIMM in either slot, then either:

a) The DIMM is, for some reason, not supported by your motherboard.

b) The DIMM is defective.

Let us know how it works out...

PS. Linuxguru: no, it's a socket 478 as far as I can see.

Probably the safest option - occasionally you just get a malfunctioning stick, even with the best brands.
