I bought from Gateway to double my ram ( 512 to 1024 ) and now my ram has gone back to 512. How can I find out which chips or whatever they are called have gone dead, the original or the newer Gateway?

go to control panel , computer , properties and the details of the chip , motherboard and ram is listed there
as the ram is itself a circuit board that is put into a slot, the only upgrade that may be possible is to insert a second board of the same make and capacity to double the ram
talk it over with a computer repair shop as to the possibility of what you want to do

You will likely just have to open the case of the unit (removing the back cover) and there should be a ram din in plain sight.

This model Gateway can support 4Gb of RAM.
The RAM you installed may not be compatible with each other.
Use RAM of the same make and speed.

the details of that board are sorta sketchy, it could be an intel 810 series or 815 series. theres really no way to tell except by opening it up and looking for the largest exposed ic chip with intel stamped on it, and look for an 810 or 815 designation on that chip.

if its an 810, it may not support pc133 ram, depending on the exact 810 model. if its an 810, it also will not support more than 256 total ram.

if its an 815, it will accept 512 total ram, if not more; however, you will have to go with no more than 4 ram sides- meaning, if you have 2 double-sided ram sticks, you will not be able to add anymore. if you have 2 single sided sticks, and a 3rd ram slot open, you may be able to add a double sided stick in the empty slot for 1+1+2=4 ram sides.

If the computer turns on then it's usually the video thats gone bad. If it's onbaord video then the you need to install a video card.

If that doesn't work then try swapping out the RAM. One of the chips may have gone bad.

Do you hear any beeps when the machine turns on?

Hi,

Any beep code from pheonix starting with two beeps relates to ram issues. If you have treid swapping the ram and it only gives the first 2 beeps then most likely the RAM controller on the north bridge or the data channels themselves are damaged on the motherboard.

You can try running a single chip of ram in each slot at seperate attempts. If it is a data channel damaged this will bypass the problem although it will cripple the laptops performance. Either way, the only permanent and proper fix would be to replace the oBo which I doubt would be cost effective on this unit.

I just installed 2 1gb chips in my mt3705 and it works perfect  so it might be a problem with your hardware.

The only reason for this is your laptop only support up to 1 GIG of RAM or 2 pieces of 512 RAM you can check this link for that specs of this laptop http://support.gateway.com/s/Mobile/2007/Tempest/1014768R/1014768Rsp4.shtml

Hope that helps............

Hello Brian -

Is the new RAM you installed the same as what you took out? Are they both PC2700?

Is your laptop running on battery when you're testing to make sure you CPU speed is accurate? The laptop usually ramps down the CPU speed if it is being run off of just battery. Plug it in if this was the case.

Also, the Gateway and eMachines laptops I have encountered have all been notorious for displaying the incorrect CPU speed at times.

I would suggest putting your new RAM in, make sure the laptop is plugged in, and boot it up. This time, let it idle for about 10 minutes and then check your CPU speed to see if it has updated correctly.

There are two different memory modules for that series.You can determine which you need by the chipset for you machine.If you have a Via VN800 Chipset You need the 1024MB-DDR333, 333MHz, PC2700, 200p SODIMM, 2.5v. If you have the NVIDIA nForce 410 Chipset The you need the 1024MB-533MHz DDR2-533 PC2-4200, 200p SODIMM, 1.8v Hope this clears up your problem
