Hello, i am trying to upgrade my RAM from the standard 512mb to my mobo(intel D102GGC2) max of 2048mb, First i added a 1gb PNY PC6400 with the standard 512mb PC4200, as i was told by PCWorld that it would be compatable. It also said on the PNY pack that it was compatable with PC4300-533mhz. My problem was, they would not work together, but both work fine on there own in both RAM slots. I thought it might be because of the differance in speeds so i went back to PCWorld and picked up another 1gb PC6400 stick thinking that would give me the 2gb max i was after. I explained it all to the guy at PCWorld and he said the two 1gb sticks would work fine with my mobo. Anyway, When i try'd it my pc would not boot, no beeps, just the fans on full and it sounds like the HDD is going through a cycle, light flash's about every second, after about 10-15 seconds HDD stops and the light on CD drive stops but fans stay on full. The strange thing is, both 1gb RAM sticks work fine on there own in both slots, but together, no boot. I have a funny feeling that the guy at PCWorld has told me a load of pooh as they had no other speeds in stock, but i do not understand why both work on there own, and both RAM slots work fine. Any help would be great because i have more RAM in my desk than in my pc.

Intel states:

"Support for DDR2 533MHz and DDR2 400MHz DIMMs

Support for up to 2GB of system memory"


Crucial confirms:


So why are you trying to run PC2-6400 (DDR2-800) in a board that doesn't support it?

Hello jam, i was not aware my board did not support that speed. Some dude in PCWorld told me it would be fine as it would downspeed to suit. I now now they will tell you anything so you spend money. Is PC6400 likely to do any harm to my board

Ram is generally backwards compatible so it *should* automatically underclock to whatever speed the motherboard supports. Both Intel & Crucial know that. I understand Intel not listing DDR2-800 as being supported, but not Crucial. Then again, Crucial recommends DDR2-667 which also isn't listed in the Intel specs. Technically, DDR2-667 is the correct RAM to run with a 533MHz FSB CPU, but it's kind of pointless to get DDR2-667 (or DDR2-800) if the board will only run it as DDR2-533.

Try updating the BIOS:

Message: Thanks for the help jam, i was thinking of updating the BIOS, But i was reading on a forum chat that someone messed up there system because the BIOS from the intel site was not the same as OEM (Gateway/eMachines) BIOS. My BIOS is GC11020M.15A.2010.2006.0817.0956 The one on the intel site only matches the first 8 didgits. There is no BIOS update on emachines/gateway site. It is only £20uk for the right RAM from the cruical scan, so i would be better of buying that instead of flashing the wrong BIOS. The only reason i went to PCWorld instead of cruical was because i wanted it the same day, 2 weeks later, and it has already cost me £50 to boost it by 512mb. I guess thats what you get for being impatient. Still dont understand why they both work on there own. Anyway, any help with with the BIOS i would be very thankfull. Gilesie17

The issue may have something to do with the maximum number banks. This is about how the RAM is assembled.

I suggest you re-install the original RAM and then go to crucial.com and use their online scanner to determine what RAM is compatible. Newegg.com also has a similiar scanner.

At newegg you will need to know what motherboard you have. To get that information download and run SIW.exe. Get it at the link below.
