Question about Dell OptiPlex GX620 PC Desktop
I've got this small form factor Dell Optiplex GX620 and I wanted to upgrade the memory from a pair of 512 MB simms to a single 2GB dimm. The existing memory was 533 MHz (PC 4200) so I figured I could just buy anything faster than that and under-clock it.
I ended up buying a 2GB strip of 800 MHz (PC 6400) memory for $30, and installed it. The system appeared to boot just fine, but when I try to log into windows, the system hangs for a moment, and then gives me a series of errors before starting a shutdown timer and rebooting.
Does anyone know if this is related to the memory speed being too fast, just some configuration problem, or something else?
Memory must be installed in pairs.

I work on GX 620 dells alot. I work on them for a school district.
They have alot of issues. Particularly with memory issues, try reseating the memory or trying a different memory slot. You shouldnt have to under clock it. Just run it as normal.
If it beeps on start up, then its probably a memory problem. The dell website has online support and will give you a list of dell beep codes
you can type in your dell service tag number located on the back, or just picking out the model.
Try using just using the new memory stick by itself without the old ones.
If your computer came with a disk ( it should) It either Blue or Black, if its black, boot from cd and it will load a test program, try using that to check that the memory is good. If its blue then its older and just lets you re-install windows.
If its looping, where it gives you a black screen with options to boot in safe mode but restarts no matter what option you pick.
Load the windows cd like your going to re-install, Boot from cd ( F12 ) on boot, pick boot cd drive and when it loads, pick ( R) for repair and when it goes to command prompt, type in. ( chkdsk C: /p ) exactly like that
it will run a repair. When done, type EXIT and hit enter.
When it restarts, remove the disk and see if it gives you the option again to pick how to start windows.
Pick ( star windows normally ) see if this works.
If the repair works then it wasnt the memory as much as it was just Dells Crappy hardware configuration.
Let me know what happens and i can try to help you further.
It could be a bad memory stick that you happened to get.
