Motherboard Won't Take 2 Sticks of RAM

I bought a second stick of RAM but the motherboard only computes one stick at a time. I have tested both sticks individually and it works with both, it just won't take the full 2GB of ram.

I go to the website and download the bios upgrade. But when I start the program in my WIN XP PRO system, it does not response. Also, it seems that if I plug only one ram in second slot, it does does notwork as well. what could be the reason? Thanks for your help.

I have a motherboard called d102ggc2 with max 2 GB capacity. I recently tried upgrading from 1 GB ram to 2 GB ram by adding another 1 GB stick. The problem is that both the sticks are not working together...

Sounds like the second RAM stick was placed in the wrong slot. I would suggest checking your motherboard manual to determine this. Some motherboard designs have unusual slot arrangements.

Conflicts of RAM and motherboard

well unfortunetly it seems as though your RAM may be bad or not compatible. My suggestion is to go to and use their easy memory finder to see what is best for your system. Then look for it else where like or tiger direct, etc. There isn't a whole lot that you can do to fix RAM like that to make it work with a system predefined by the maker.

A7s333 motherboard with 3 dimm ram slots 2 x 1GB pc2700

That board type does not show on the ASUS web site. I think that your problem may be incompatibility of the RAM with the board specs. Placing faster RAM on the board will not make it go faster.

Total amount of RAM not recognized by computer

are the modules the same specs? you may have some incompatibality between them. the board may be reading the ram right it may be you have four 256 sticks instead of 2 of each. read the motherboard manual it might shed some light here.

My computer keeps booting every 2 seconds and I just can see motherboards first screen during 1 second then cant see anything else

I am almost positive it is the ram, because it gets to windows but crashes after loading windows partially. I once had a similar problem. Just make sure all the Power Supply connectors are properly connected.

Try these steps too:

1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button (this discharges any residual power in the capacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.

5. Unplug and replug all the power supply cables.

6. Check the powersupply function. Either by a powersupply voltage checker (20-25 dollars at local PC shop), get the supply tested at a PC shop (usually a free service), put the powersupply in a different pc, or try a different powersupply in the problem computer.

If the Powersupply checks out ok, then you will have to do a process of elimination to find out what part or parts are the culprit of the No-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots. Try one stick at a time to see if you can get the PC to boot. If this works, then the remaining ram sticks are damaged.

Two rams stopped working in intel d101ggc from today

You've got either mismatched RAM memory or 1 of your sticks are bad. You can isolate this by booting 1 stick at a time. If the machine boots fine with both sticks (one at a time) then they are mismatched or your motherboard isn't configure to handle the 2 sticks together (not very likely but a possibility) Hope this clarifies your problem All the best!

Motherboard not recognizing RAM

Is it exactly 3gig of ram?
You may have 4 sticks in but your onboard peripherals share the memory.
as such my 512mg stick is in but it shows me only 482mg.
Take into account your onboards.
Hope this Helps
