I want to replace 2 sticks of Ram in a 2 year old Mesh machine for someone else.

They are 2gb sticks and are described on the label thus:

2GB 2Rx8. PC3-10600U-9-10-0.1333

If I haul them out and replace them with these

That should work ok yes?

[Ghozer]

Yes should work, but why do you need to / want to replace them?

[Tony Erikson]

Can't see why not.

Thanks chaps.

Want to replace them because the computer is behaving very strangely.

Sometimes it won't even start up, failing to show the Asus motherboard screen, or freezing on the American Megatrends screen. If it makes it to the grub bootloader, then everything is ok, windoze 7 loads up nicely. Then if you actually try and do something the computer will either
a) freeze completely, and faint horizontal pink lines will appear here and there on the screen.
b) freeze completely and scramble the screen into horizontal lines
c)BSOD briefly before shutting down
d) just freeze, no mouse or keyboard action, even with a wired ps2 effort, no response from the cd player etc.


Then sometimes it continues without problems, working normally for hours, before something happens.

Took one of the sticks of ram out - no problems since (72 hours and counting). It's no-namo© brand RAM, and I wonder if one of the sticks isn't entirely perfect.

Sounds like a CPU issue to me. After replacing RAM modules, you'll know for sure though...

Tried memtest?

It could also be the graphics card, overheating, power supply issues, motherboard problems, almost anything. Memory seems a likely cause, especially as it works after you took a stick out, but you need to run memtest & monitor temperatures & voltages too, to make sure.

I'd do a diagnostics on the mobo before buying replacement parts that can be expensive.

I don't know of any specific motherboard diagnostics software. Memtest will test the memory, as it's name suggests. If memtest fails, voltages are stable & temperatures aren't too high, then it's likely to be the memory.

You can download a bootable iso of memtest86+ here: http://www.memtest.org/#downiso

Look in event log to see if those bsods were logged, the errors may give some clues.

Also look for dodgy capacitors on the motherboard: http://badcaps.net/pages.php?vid=5

OK chaps we ordered the replacement RAM - Corsair Memory — 4GB (2x2gb) Dual Channel DDR3 Memory Kit (CMV4GX3M2A1333C9) [ http://www.corsair.com/cmv4gx3m2a1333c9.html ] and stuck it in and didn't even get to the mobo's screen (ASUS M4A78LT-M LE mainboard (DDR3)).

Everything I see tells me that the original memory sticks (M2Y2G64CB8HA5N-CG) [ http://www.elixir-memory.eu/download...-UDIMM-R11.PDF ]

should be interchangeable with these corsair sticks - but clearly they're not.

We have been running the comp on one 2 gig elixir stick for weeks with no problem, so we think we're pretty sure that it was the other stick causing problems (confirmed when we ran the comp on the "questionable" stick, everything went awry).

I am so not a hardware person, and have no idea why this isn't working - can anyone enlighten me?

Thanks in advance!

Did you put the old memory back and see what happens?

[Phanerothyme]

Yeah, the working 2 gig stick is back in and the computer's running faultlessly.
