Several long beeps means there is a problem with the memory. First of all make sure the memory is seated in the slot perfectly. There should be no movement whatsoever when you gently try to rock it side to side. If it still persists the bad news is the memory is most likely shorted out or defective. They are VERY sensitive to static electricity. I would go ahead and put the old memory back in for now and send the new defective memory back. Most vendors will issue you a replacement free of charge if you let them know it's not working.

Hope this helps!

This is what you need to check. No matter what Dell says. Make sure that the old ram and new ram are the same speed. If the old ram is not PC-2 4200, than you need to get the same type for the upgrade. If this is correct, and you have matched them, old and new, than take your new ram, PC-2 4200, and exchange it for PC-2 5300. This will solve your problem. Some motherboards don't like certain kinds of memory. Mine came with PC-2 4200, and i tried to upgrade, it did not work. I had to go to PC-2 6400 to make it work. Also make sure the new ram is seated in it's slots. And the tips, on the ram ports, are locked onto the ram. Good luck.

Yo have the corect memories chips. However, you have to isntall them in pair.
if the machine still give you the error beep code, then either you have the wron g memories, or one of the chip is bad. have them tested.

I want to upgrade my power supply for the dell gx280 small desktop


Sorry to say that a 260w PSU is the largest PSU you will get for this system as that is all the M/B is safely rated to any higher than that and it may cause a fire or worse. I run a Dell GX270 and this is maxed out on a 260w PSU. This system will only be upgradeable to these specs :

3.2Ghz CPU ( Note they must match existing letters on CPU.
3Gb Ram under XP, 4 Gb under Vista or Win 7. ( Note win 7 will run very slowly )
256Mb PCI Card or 512Mb AGP (4X or 8X )
500Gb IDE or SATA HDD
DVD Burner max ( Blu-Ray will not work as it is too advanced ).

Even the tower model of these systems only have a 260w PSU max due to limited power rating for the M/B. Tower PSU is able to be swapped out just like any other tower but the fact remains that the M/B is only rated to 260w and if you use a larger PSU it may cause a fire or worse. I hope this helps.

Issues with 2gb 32ddr dell memory compatible in dell gx280


Unfortunately, the CPU on these computers may be capable of handling the 2GB memory, the motherboard isn't on either system.

The specs for the Dell GX280 are available here: http://support.dell.com/support/edocs/systems/opgx280/en/ug/specs02.htm . This system takes 400 or 533 MHz DDR2 non-ECC memory and the form-factor determines the maximum memory. In the mini-tower format, you have 4 DIMM slots and can have 4 GB of memory. In the small form factor, it takes 2 GB max.

The Dell E310 specs are available here: http://support.dell.com/support/edocs/systems/dim3100/en/sm/specs0.htm . This system can only support 2 GB (2 x 1 GB) memory.

I wish that I had better news for you.

Cindy Wells
(who had a similar Pentium 4 computer with the 1 GB limit. Since that system was running a 32-bit system and only actively addressed 3 GB, I didn't try to put 2 GB sticks in any of the 4 memory slots.)

Acer desktp internal ram installation needed


I'm a bit confused....did you have all four of these in the ACER and are trying to put the 2x1GB into the Emachine? And that the 2x1 GB wouldn't work in the Emachine but they did in the ACER and that the 2x512 Acer cards worked in the emachine?

If that is what happened here is my best guess. The ACER MOBO will support 533/667/800 MHZ DDR2 RAM. The Emachine will only support 533 RAM. Iys possible the 2x1GB are either 667 or 800 MHZ and are not compatible with the Emachine but will work in the ACER.

How much RAM can my MOBO take?


Hi,

The laptop has 2 memory banks. Each bank will support 1GB 400Mhz, so maximum memory the motherboard supports is 2GB.

If you plan to change the graphics card, then go in for a card that has a lot of dedicated RAM. Not shared. You may be able to do with 2 GB RAM on your PC. Ask the dealer specifically.
