Sorry to hear of you issues.. I had a similar issue with a predecessor of the 6000 the  e1505.. It was deemed to have a faulty motherboard and replaced never to have the same issue.. It is more likely that a systemboard have generally the same defect than seperate and different.. Have you tried running the system with 1 modual instead of 2 if the board is bad it is unlikely both memory controllers and/ or sockets are bad.Try switching I dimm within a/b slots and running the tests.. It is possible that your video card could cause it because it is tied in with the board for the hypermemory function. I would do the dimm socket test first.. Good Luck..

Yes I did the DIMM socket test.  as mentioned previously each module failed on either slot whether singly or together.  I replaced the motherboard at least once already but got the same errors.  Tried the single slot test for that board as well, same problem.  Not sure how to test the video card without buying a new one.  I hate to keep throwing money at this thing without knowing for sure what is causing the issue.  I can say the video tests in the dell diags all pass, only the Memory DMA test seems to fail. 

 

What do you think is the more likely? A second failed board or the video adapter?  I removed all other devices but the video with no success.  Unfortunately this board requires a separate video card to work as it does not have built in video.

Sorry it has taken me so long to post back but i have been trying different things to fix thios system and now i could REALLY use some help.  Hopefully someone will see this and reply. Besides the above, i havew now tried a total of 2 new mobos, and a new video card and the same exact error continues to occur.  Bout the only thing i have not replaced or removed for testing is the CPU.  At this point i am not willing to replace that since i am not convinced that this could be the issue.  Funny thing about this system is that DOS level OS'es work fine and dandy.  Even flashed the bios on all three boards and had no errors.  Right now i have three motherboards, all two of them new and one original, 2 video cards, and 3 sets of memory, 2x256mb, 1x1GB and 2x512mb all give the error code i mentioned. 

 

So here is the question or two:

 

1) how likely is it that the CPU is bad and is there a way to test this theory without replacing it to do so?

2) What else am i missing?

 

For reference again, i have swapped out the motherboard twice, replaced the memory twice both in pairs and in each slot one at a time, replaced the video card, removed all devices such as the modem and wireless card and yet i still get the memory failed error on the dell diags with the error code of 1000-0123.

 

Signed: Desperate and looking for a miracle!

Hi,

 

I had a smilar problem with an Inspiron 6000.  Thought it was a video card problem at first.  The computer was always failing memory tests giving error 1000-0123.  The problem was the processor.  I am pretty sure that this is your problem.   You will probably want to get your hands on a replacement cpu to fix the problem.  Hopefully this helps.  eBay's probably the best place to get a good inexpensive one. 

 

Thanks,

Mike

 

Yup, that was it.  For everyone else out there, if replacing the memory, mobo, and video doesnt fix it, replace the CPU.  got the system up and running fine!  now to return the unneeded parts...
