Question about ECS C51GM-M Motherboard

1 Answer

Added a 2gb ddr2 to top up the 1gb but now I only get a bleeping sound.

Had 1gb ddr2 667mh pc5300 already in pc and added a 2gb ddr 800mh pc2-640 to it. Which the computer shop said would be fine. Now I am only getting a bleeping noise when started. Tried removing the 1gb and replacing it with the 2gb, but still the same outcome. Any help appreciated.

    I dont believe its a dust issue as the original 1gb ram works ok in the same slot as i tried the 2gb one. the ram has a notch in it so it can only go one way. I have taken it back with and the shop no says its not compatible with the board. Thanks for your coment

    have tried putting in a 1gb ddr2 with exact specs as the 1gb already installed. Still only getting a beeping sound. Have removed original ddr2 and put new one in slot but same result. Old ddr2 works in any slot but nothing from new ddr2. Is it possible its a bad ddr2?

    Yes a ram module can have a defect. Maybe one of the ram slots is defect. how many beebs comes when you start up ?? Maybe he has sold you a wrong type of ram. Bring one of the old ram and let him look at it. I am 100% sure its a ramfailure

    The new ram is identical to the old one. The old ram works in either slot and the beeps are one -two seconds long about every 4 seconds. Your help is appreciated

Hello you can download a manual here:

Try to clean the mainboard for dust with compressed air
and let your dealer search the ram module for a defect.
The spec. for the ram is this:

You have maybe not insertet the ram correctly.

Good luck

Memory upgrade 2gb 4gb

The CF29 comes in two basic flavors:
#1: With 256MB RAM and DDR Ram with One open slot.
So add a 1GB DDR RAM (PC-2700) DDR 333 and
the maximum RAM is now 1.2GB

#2: With 512MB RAM and DDR2 Ram with One open slot.
So add a 1GB DDR2 RAM (PC2-5300) and the
maximum RAM is now 1.5GB.

This is my experience and very frustrating to find out the
hard way that the CF29 does not support a 2GB DDR2
RAM Module.

Good Luck.

I bought an Acer AO532h-2964 netbook, and I'm wondering: can I upgrade the RAM from 1 GB to 2 GB, and if so, which memory chip should I buy?

yes you can, your netbook can have a max of 2gb ram and a max module size of 2gb.
So you have 1gb pc 5300(ddr667) installed, and you can buy 1 more 1gb module, laptops use sodim. has a 1gb stick for £25
you could also try / amazon / ebay

Pc5300 on pc3200 slot to upgrade msi 845gvm-v

PC5300 or more correctly "PC2-5300" and can work in a system that has "PC2-3200" RAM, and if mixed, they will operate at the speed of the slowest module. "PC-3200" RAM, however, is not compatible. PC-3200 is DDR SDRAM, having 184 pins. PC2-3200, and PC2-5300 are DDR2 SDRAM, having 240 pins. DDR and DDR2 modules are the same length,
but the pins on DDR2 are smaller and the keying notch is in a slightly different position.

You need to get the replacement ram all the same type ie - DDR or DDR2

And yes your motherboard should accept 2GB max
