Hi
I don't know what BIOS version you are running presently but this is an issue with this motherboard and certain BIOS versions. From memory I think it was with the first one FA. If so try updating the BIOS to the latest one and see if that cures it. Don't forget to use QFlash to do it and tick the disable Keep DMI Data.

You need to make sure that is the case. Make sure that you have it in slot 1.

If one is totally DOA then that is easy but I would make sure before RMAing them both.

Did you buy them as a matched kit?

Looks from your pictures to be the standard problem with FA.

DOA is short for Dead On Arrival.  ;)

As I said it seems to be the standard problem with BIOS version FA.

You will need to update your BIOS using QFlash to the latest version. I take it that you are using the revision 2.0 board?

Please be aware that I have the same gear and the same problem

By updating your BIOS you will be embarking on a nightmare of cold boot errors and other boot problems even by using the latest Fe1 beta BIOS

If you can live with it stick with the 4Gb problem until a  BIOS workaraound has been produced.

I have been fighting this problem for 10 months

The latest beta BIOS is the best yet but still causes problems on cold booting

To be fair Bob I know that is what happened in your system but it may not present itself in the same way on a different system. As we know most configurations behave differently even if they are very similar. I would think it would be usefull to you to see what the OPs computer responded like in this situation.

There is nothing to stop you trying it and then if you do find that you have the same problem as fatbobuk you can always flash it back to FA again.
Just make sure that you use QFlash.

Yes I thought it was revision 2.0 so that should be fine.

hey i heared about dual bios.....is there any way i can reset my mobo to my FA bios after flashing the new bios?

is it related with dual bios?

Post by: Dark Mantis on December 15, 2010, 03:24:04 pm
Yes it is possible but I think that it would be easier to just re flash with QFlash again.

re flash means...but i thought that the new mobo is working gud so i don,t want to take a chance so how can i use dual bios?
Title: Re: x58-ud3r showing only 4 gb usable ram out of 6 GB ram.
Post by: Dark Mantis on December 15, 2010, 03:54:49 pm
Dual BIOS is just that you have the Main working BIOS and a secondary Backup BIOS for if something goes wrong.

Post by: mspunk166 on December 15, 2010, 04:02:19 pm
so how can i use it? means i can make new bios as seconday and FA is saved for back up?

so how i can do this?

but consider this also (i thought  that only 1 module is not working because when i only put that module in slot and try to switch it on..ther is no display on screen) ???

Sorry I got distracted by Bob earlier and the BIOS.  Yes if you are sure that the module doesn't work when inserted then send it back or if it was a kit send the both back for replacement.

If you still have any problems post back and we will see what else can be done.
