Question about Dell Dimension 2400 PC Desktop

4 Answers

PC beep 5-2-2-1 code on startup, no posting

I'm getting a new PC because my Dell 8200 mobo appear to have die. I try to upgrade my memory from 512MB to 1GB. These are expensive Rambus memory. The type are Non-ECC. I got by mistake, ECC type. But I install them anyway because I was told they could be mixed as long as they are matched in pair. After installed them and power up, pc won't boot(no video) and hear a beep sequence of 5-2-2-1 and LED at back panel are green, yellow, yellow, yellow which according to Dell manual "no memory detected". Took new memory out and put everything back as before. PC will not boot and beeping. I RMA the new memory and received the correct one. They are the same Samsung part # as the original one. Install them. Still won't boot. Try different combinations. No good. Try to reset BIOS by removing CMOS battery. No good. Talk to Dell. They said I should buy memory from them at $400. They think the memory was incompatiable and may have shorted out the mobo so that even when I put the old memory back it didn't matter. I don't have tools to see if memory is getting power. The mobo light is on, the fans are on as are the drives. I don't know what else to try so. I suspect the mobo did not like the memory and won't boot and is stuck in that state(remember) no matter what I do. I may be wrong about that. So if anyone have a suggestion/solution, please let me know.

TIA

    I only have 4 sticks and they have to be install in pair. I try different combination with these 4 plus the 2 continuity(dummy)modules. No luck. Is it possible that the mobo didn't like the memory and won't boot and remember that so it won't boot no matter what I do?

    TIA

    BTW, Dell charge $250 for a refurbish mobo but has warranty to work. I know ebay has it cheaper but don't know if they work and I never replace a mobo before.

  • yman1949 Feb 05, 2009

    I just realize something that may or may not be important. For 2 -3 weeks before I try to install new memory causing my problem, the pc sometime reboot for no apparent reason. I could be surfing or working on something. I think this happened 3 times or so. At first, I ignore it but when it repeat, I thought I may have a virus. I ran a virus scan using Norton but nothing shows up. The last time, I left the pc unattended for a few minutes while left a web page open. When I return, the pc has rebooted but window was stuck at the Welcome screen. I have to use an image to restore the pc. So I don't if this is related. Could I have a virus problem or maybe a power supply problem which is recycling. If it is a virus, what can I do now? Also if I get a new pc, I plan to move my hard drives over to the new pc. I'll reformat the C: partition and use it for storage. If it is the power supply, replacing it would cheaper and may be easier than a mobo. But how can I tell? I don't have much tools or experience on this. Any thought or idea. Am I barking on the wrong tree?

  • yman1949 Feb 05, 2009

    I have a Dell 8200 which for this model uses RAMBUS RAM, RDRAM. Dell switch to DDR RAM for 8200 after I brought it. It is faster but not worth the expense and headache. I installed a serial controller card so I can have SATA and IDE PATA HDD.

  • yman1949 Feb 05, 2009

    I did switch the video card to a spare one. Didn't make any difference. If PSU is not the problem and I doubt this can be cause by virus. I don't know what else could it be other then mobo.

  • yman1949 Feb 05, 2009

    Thanks Astrophel and everyone for your help. I decided to shop for a refurbish pc rather than spend money on a new mobo and not knowing if that will fix the problem. Plus, I never replace a mobo before. I find a refurbished Dell GX280 small tower for about $205 plus $39 shipping. It is "Dell OptiPlex GX280 Tower 3.0GHz 512MB 40GB Windows XP Pro" with a !GB memory upgrade. Any opinion on the system or price. This is the linkhttp://www.hcditrading.com/Shop/Control/... . Don't know if seller is reliable. This is what worry me the most since I never bought any refurbish stuff before. Let me know.

    TIA.


  • yman1949 Feb 05, 2009

    No Vista for me.

  • yman1949 Feb 06, 2009

    Thanks Astrophel. Appreciate it. I am worry about buying a refurbished pc. I don't want another usable box in my basement. But it may allow me to wait till window 7 comes out and if it is good, I'll buy a new system then. That was my original plan till this happened.

    TIA

There has been an issue with 2400 ... i am sure this is not a memory card issue as it is u will be shocked to know this ... GYYY is not listed with dell as a failure ... the memory card failure is YYGG and but again the beep code that u said are 5-2 2-1 means compatibilty of memory cards so either is come confusion ... u can try one thing .. which i am sure may resolve the issue ... reseat the processor and heatsink

    if that did not work ... just one option left ... disconnect the power cord from the back of the system and than hold the power button for 10seconds and than connect the power cord and try again

    if that doesnt work u have to change the motherboard ... better option i would say is go for a new dell system u get a new system in 350$ call 18006249896 and ask them about the new systems and they will guide u acordingly

I would try a few more things:

just make sure that the memory is correctly installed in the correct slots to make matched pair, RAMBUS memory must be paired exactly. If they are not in the correct slots, they will not work.

The price of the memory is probably more than a refurbished computer that performs much higher. I would keep trying to swap the old memory I had, and return the new memory.

Make sure to Flee power each time you switch memory between slots (although board may be done)

Flee Power
* Disconnect the power cable
* Hold power button for 15 seconds
* Release the power button
* Plug in power cable
* Start the computer

    For that money, you can probably buy a refurbed system from a local shop ot tigerdirect that will outperform your system with the upgrade

    A faulty power supply is unlikely to be the cause of this error.

    I have seen the interaction of Video Card memory cause System memory error codes. (you could check by removing the video card, since the video card is checked after system memory, if the code changes, it may be the video card). However, everything you describe still points towards the motherboard, even restarting can very easily be caused by this.

    Also I just quickly searched for Motherboards for this system online. It looks like most use standard DDR, so take care that if you buy one of those you also need to replace memory (although that would still be cheaper than Dell's parts.

    About re-using the hard-drive, the 2400 has PATA drives, while any new system you purchase will likely have SATA connection. There are PATA->SATA converters available, but they tend to be a little flaky. I usually suggest you buy a Hard-Drive encloser that supports PATA IDE drives, and use the old drive as external backup storage.

    Ron Feb 05, 2009

    ??? I just verified the specs - Dimension 2400 seems to use DDR not RAMBUS memory ???

    Am I missing something here? RAMBUS will never work in a DDR designed system. I thinks somewhere along the line, some confusion occurred. Standard DDR does not necessarily need to be paired to work, but is preferred for performance


  • Ron
    Ron Feb 05, 2009

    I agree, a virus would not give you a POST error.

    If you do decide to purchase parts, make sure you clarify any return policies. This is still a very useful computer, but you need to make sure you do not spend more money on it than it is worth.

    You may just want to go new, Dell often does not charge you for shipping so a basic system is $279 with Vista (you already have XP).

    http://configure.us.dell.com/dellstore/c...

    1 year warranty
    2GB RAM
    DVD writer
    320GB Harddrive

    Was just an idea, the 530 does support XP, and uses standard Dell XP Install Disc, exactly like the one that comes with a Dimension for example. All XP drivers would be available at support.dell.com. If you do not delete the restore partition, then you can restore it back to the original OS anytime (unlike the old restore that came with XP systems)

    just a thought

5-2-2-1 beeps refer to Unsupported RIMM device count/technology, so the issue is that the ram that you used, you should have verified whether they are the correct one, may be as per all your statements, if you have two RIMM modules installed on your computer, try with one RIMM combination and see if it works, otherwise go ahead and replace the mobo,,,

Did you try to install one stick then see if it boots if it does move that one stick to all the different slots to see if you have a faulty slot and then see if you have a faulty stick by rotating them

Memory upgrade on gx280 beeps on boot but doesn't start. memory beeps 1 234 5 6


When your computer emits beeps when you power on the computer, it's usually means that you have a memory issue. Try re-seating the memory modules and power on the computer. If you have more the one module, insert one at a time and power on the computer. The other issue is if that model supports 4 gig memory.

My dell beeps once then three times then twice. just a blank screen


Thats called a post beep. You may need a new power supply....also check your internal fans to make sure they are spinning. Make sure memory is seated properly. Motherboard may also be in question. Try unplugging letting it sit for a few then plugging back in.

I want to add more ram. Where do I get it? Dell


I hate to be the bearer of bad news, so don't 'Shoot the Messenger'!

The Dell Dimension 8200 Desktop PC uses RDRAM ram memory.
VERY expensive stuff!

Supporting Data:
This is Dell Support, Manuals, and the Dimension 8200 Service Manual,

http://support.dell.com/support/edocs/systems/dim8200/

Scroll down the list to the heading - Specifications, and left-click on it.

Scroll the page down until you come to the heading - Memory
Now look at the first subheading - Architecture
RDRAM

You have 4 ram memory slots. (memory connectors)

EACH, ram memory slot can support up to a Maximum amount, of 512MB. (512 MegaBytes)

TOTAL Maximum Amount for your computer is 2GB. (Not shouting)

1024MB = 1GB. (1024 MegaBytes = 1 GigaByte)

The type of Rdram ram memory is PC800, and it is Non-ECC.

(Error Correcting Control, or also stated as Error Correcting Code.
Used mostly for Server computers. Your computer does not use ECC ram memory)

In My Humble Opinion, (And again, don't shoot the messenger), it would be better money spent to buy a decent affordable computer, than it would be to upgrade the ram memory in this computer.

This statement is based upon the fact that the Dell Dimension 8200 ships with 128MB's of ram memory.
(Makes it a pretty slow computer. Rdram or not)

The average cost to install, for example, 1GB of ram memory is OUTLANDISH! (Not shouting)

Example 1:

http://www.4allmemory.com/index.cfm?fuseaction=search.memorySearch&model_id=24927

Example 2:

http://www.pcmemorystore.com/Dell-Dimension-8200-ram.htm

For about another $100 you can buy a pretty decent new desktop computer, that will run the one you have in circles.

Just my thoughts.

Turning on my gateway 510 x PC I get a black screen/white cursor


Did you make any changes recently (add memory, etc.)? Does it make any beeping noises on startup? I've had this problem occur when putting in the wrong type of memory. If you haven't added memory and there is beeping on startup, find the manufacturer of the MOBO and you should be able to find a beep startup code to tell you what the issue is.

"my computer will only beep no screen,it beeps


Hi

You likely have a bad memory module. First, try removing all the memory and putting it back in again. This is called reseating. If you still get the errors, then try removing one stick at a time and testing it with each stick (provided, of course, you have more than one stick installed). If you only have one stick installed, remove it and turn on the computer and it should beep at you as well. That memory stick will need to be replaced.

Thanks and please take a moment to rate this solution as fixya. Thank you.

Dell 2400 ram upgrade problem


RAM can be finicky so first test all memory slots with a known good stick (your 512MB). Make sure you're starting from a complete power down and you get a POST beep (hopefully your system is set up to beep when it powers on) and everything loads up all the way through to your OS.

Once you do that with all your memory slots test with the new stick by itself in all memory slots. If neither of the memory slots work with the new stick but you verify that it works in another system you should then check your BIOS settings and RAM timings to ensure compatibility with your stick. If you can't find the timing on the RAM stick itself, look up the manufacturer's part number for the information.

Good luck!

Added a memory stick to my Dell 2400 Desktop computer and the monitor, mouse, & keyboard won't work


Hi

The supported Memory types for Dimension 2400 Series is PC2100 (266-MHz) or PC2700 (333-MHz) DDR SDRAM (non-ECC). Supported Memory capacities are 128, 256, or 512MB and a Max if 1GB (1024MB).

The first obvious question is does the new 512MB Memory module meet the above specification? Some Memory modules are able to steep down speed.

If it does, then first ensure the new memory module is properly installed. Take ESD (ElectroStatic Discharge) precautions or you may damage the new memory module and/or the system board.

To proceed compare the system beeps and diagnostics lights color and sequence to the Advanced Troubleshooting guide.

It is possible that the new memory is DOA (Dead On Arrival). Or there is a new fault on the system. If you have access to another compatible system, you may test the new and old memory modules. You may also swap the new and old memory modules to determine if the memory slot is at fault.

Lastly, if you remove the new memory module, does the system complete POST (Power On Self Test)?. If it does you may indeed have a DOA or incompatible part.
