Dell gx280 memory

Ive just acquired a gx280 desktop with no ram, i put 2 1gig sticks in and nothing would come up on the screen but there were beeps a couple of times i tried it. after closer inspection of the ram it turns out that its pc2-3200R. by this time it now doesn't beep and the fan runs flat out.
would this have now damaged the motherboard?

    have now put the right memory in, but still no go, fan runs flat out. the only way ive found to make it boot is to apply pressure to the top of the fan on the one side, it will then boot up but when running the fan revs up and down some times to deafening speeds when in use.

    what could be causing the problem? processor socket nackerd?

    processor cooling fan. sounds like a jet-engine. the more load thats put on the computer the harder it spins. i know with these type of pcs the fans operate to load placed on the cpu but this is rather excessive.

  • naymx5 Feb 08, 2009

    no dust,quite clean in side the case and in the fan / ducting. the noise is caused by the shear speed its running at, its running way above 6000 rpm from what the system has said.

  • naymx5 Feb 08, 2009

    ive had a good look and they all look fine, no leaks or bulges. i have another board that does exactly the same as the one im using currently. will only boot if you push down on the exhaust side of the fan ducting and when running under normal usage the fan is flat out.

    these pcs are from a collage clear out of dud pcs they couldn't boot as they have replaced them, there typicaly out of warrenty when they gave up.

It sounds like the memory is the wrong type. you should get SDRAM-DDR2 at 667 MHZ. pc2-5300.

    Which fan are you talking about?

  • Matt Barr Feb 08, 2009

    Is there a lot of dust in the system? ive had this clog up the fans and cause them to make a lot more noise than necessary

  • Matt Barr Feb 08, 2009

    I beleive this system is part of a very large batch that dell sent out a few years ago that had motherboard issues. if you look around at the capacitors on the board, do you see any that look "popped"? They dont open up, they just bulge a little on top.

Dell optiplex gx860 continuous beep

This indicates a motherboard problem, first remove the ram one stick at a time and test as you go, if one stick is bad the computer won't start up. If memory checks out, remove hardware one at a time and put back as you check up the ladder, if all checks out the motherboard is the most likely issue.

One long continuous beep on startup

That's a RAM error. First, open it up, remove power cord and remove the RAM sticks then put the power cord back and turn it on. Will be the same beep. Then power off, put one RAM stick in, and power on again. If no beep, put the other stick(s) in (it may be just a bad contact). If same continuous beep, remove stick and put the other one in, by the same procedure. Power on again and see if the continuous beep is coming again (if it's not, then first RAM stick is faulty). This way you can see which RAM stick is faulty further on depending on how many RAM sticks you have. If it does it on all of them, it may be the slot(s) that is faulty you can only figure it out with a new RAM stick.

Need instructions on how to install Memory module for OptiPlex GX280

ok lay computer down plat. there are two grey buttons on the side.
compress both at same time.
lift and unit should open
you will see one or two green sticks about 3inches in size sitting in a slot call a address bus. on each end on the slot there are one lever to release the ram from its slot. . make sure you have unpluged unit from the wall socket. DO NOT stand on carpet this will release ESD. elictro magnetic discharge. remember which way the ram stick is facing press down on both end levers and remove the stick from its seating.
put new ram in the same way you took the old 1 out . levers will snap back up into place when you have it seated correctly.
close unit and boot unit. if a blur screen appears shut down and reopen unit repeat procedures by switching the rams around. if problem persist your ram is not compatible and you may have to get a two 512s or so on. i hope this was helpful.

Installed RAM and now I get 3 long beeps and no visual...???

3 long beeps signifies that there's a problem with either the RAM or Video card. You have to make sure that the RAM is compatible with your system. This is what usually happens once the RAM is not compatible with the computer.

Well, I reseated the memory and problem was gone - it did seem like the memory was kind of "loose" - perhaps from shipping (bought this used).
The link to Dell's website was good for the beeps AND the "ABCD" codes reading on the back. Thanks very much! God Bless.

Long low bleeps after adding RAM

it is either incompatible or dead.  try it in another machine.  if the stick of ram runs, it is likely an incompatibility.  refer to your documentation included with the motherboard/laptop (you didn't clarify) to see what it supports.  there is actually a huge difference between pc100 and 133 (which are now obsolete) and ddr2 and ddr3, although they respectively share similar pin count and layout.

Beeps, wont boot up

Most of the time when it beeps, and there is nothing show on the computer screen, it is a RAM problem. A stick of ram may have gone bad. If you have two sticks of ram in the computer, you can try to remove one stick at a time to see which one might have gone bad.
