Gigabyte GA-EX58-UD3R help

[bobfluff]

Hi,

I am having trouble in that sometimes (but not always) windows 7 tells me I have 6GB of RAM but only 4GB is usable.

I am using:

Motherboard - GA-EX58-UD3R rev1.6
RAM - F3-12800CL9T-6GBNQ
CPU - i7 930

I have tried to use the BIOS settings from similar threads but none seem to correct the problem.

Any help with the settings would be much appreciated

Kind Regards

Enable the XMP Profile to see if that helps. Also, try reseating the memory and make sure they are firmly inserted.

Thank you

No XMP profile

Thanks for the advice.

The XMP profile is not displayed in the BIOS. Is there any reason for this?

Thanks

It should be in the BIOS section titled M.I.T. (Motherboard Intelligent Tweaker). It's gotta be there.

No XMP

Hi wevsspot,

Its definitly not there, I have checked against the manual.

I also flashed the BIOS but it didn't help

[wevsspot]

That's weird. I'm looking at page 42 of your owners manual and it clearly shows that the XMP setting should be available as long as the installed memory supports it.

I'll get back with some settings that you can try.

Regards,

JW

Leave all other memory timings on auto

If the above settings don't work, please post up pics or a template showing all of your BIOS settings so we can pick through them.

Looks good for now

Hi wevsspot,

its running good for now, i'll post a template if it reverts back to 4GB.

Thanks for your help.
