adding RAM to a Gateway GT5432

a right way to place the DIMMs for optimal performance and it doesn't work, you're stuck.

Check your system manual. If you get the 2-1GB DIMMs working in say channel "A" ... you should be able to see 'Dual Channel' or 128bit Memory Operation during bootup. Once you get your system running in the dual channel mode...then add the other pair of 512MB DIMMs. If it doesn't work ...then it doesn't work and you'll have to remove that and accept the limitation. That's why I always recommend getting all the RAM you expect to install when you buy the system as adding RAM later can be tricky.

Let us know how it turns out.

What might be happening, is the proper slots need to be used as in the matching pairs(banks). If this has been done, then check the manual or visit the support website for the true amount of ram supported. Verify to clean the slots of any dust, wipe them down with alcohol(brushed) for all contacts and allow to dry. I mention this as the current PC *MAY* only support 2gbs installed, total. A possible solution if you never bios updated and this is an old PC, right??? By updating the bios, *MAY* allow better handling of ram or more of it, provided it addresses this issue. Crucial may have suggested greater than 2gbs installed but of course it can only suggest this if the PC is at its best and also as an "generic suggestion" per mtrbd. chipset used. Gateway, upon using the bios area, should affix the issue if ram can be reset. I don't have that in front me, so its up to you what gets displayed and *SAVE* any changed setting before exiting bios. However, this also reflects on the current bios status, thus it must have the latest bios update installed. If you need to bios update, review the process carefully and proceed. Last, because all slots are being used and an old PSU, there *MAYBE* a need to tweek the ram voltage abit to better handle all installed. Don't do this unless the bios allows it, Gateway could very well not have this as an option, a voltage tweek setting. If it does, tweek it by .01(MAX .03 change), save then exit and retry. Do only this as last resort if capable.

Review the Q&A they provide.

The Your GT5432 will handle 4 gig of RAM, PC2 (4200) 533Mhz. You can not mix memory speeds. Are all 4 modules the same speed? If you go to Gateway's site, you can enter you CPU's serial number. It will give you vital information on your system. You maybe able to use Gateway's Tech support. Remember times are tough, and most manufacturer's do not want to offend a customer base.

What is puzzling is:
(1) Factory system auto detects 1 gig and it boots.
(2) Installation of 2 gig boots. That means the BIOS auto-detected.
(3) Install of all modules, no boot. And you said you could not enter the BIOS or something (your words).
Sometimes you have to press the key "repeatedly".

Willys' advise was excellent.
(1) Add the 1 gig set, and enter the BIOS. Is it detected now, as 3GB total? If it's detected, you need to SAVE the change.
(2) Updating your BIOS is also good, but you have to follow the directions very carefully. It can be gut wretching.

BTW... It maybe a simple as you need (4) 1 GB modules. It may require all modules to be the same when using 4 slots. Gateway is the most difficult website to seek indepth info unless you have the serial number. I was unable to research it. HP offers the most resources, and freely.
