2.75GB RAM limitation on DFI Lanparty 925X-T2

Hi guys,

Recently upgraded the RAM in one of my machines from 2GB upto 3GB. The problem being that the board isn't recognising more than 2.75GB with any given combination of sticks.

Whatever combination I try, a selection of 512MB and 1GB sticks register correctly but no higher than a total of 2.75GB. I've already flashed the BIOS to the latest available (13/1/2005) but there was no difference.

Is there some weird memory limitation on the i925x chipset that I'm missing out on?

Cheers.

Possible 32 bit O.S. limitation?

What is the full spec. of your system, particularly the graphics card.

Look for a memory re-mapping feature in the BIOS

I know on my ASUS i have to set memory mapping to 'enabled' to go beyond 3GB in windows.

Shame, i did have a DFI lanparty but i dont remember the BIOS too well.

Its not unusual depending on hardware confiuration to only see 2.x gig of memory available in windows with 3+gig of RAM on 32Bit Windows.

Hi guys,

Thanks for the comments. I'd like to say it was only limited to Windows but the BIOS is also showing the limitation too.

p3ndldgny2, I had read something about that but couldn't find anything similar in the BIOS. I even reset the BIOS to defaults in case I'd inadvertently changed something.

The machine has a 64MB GeForce 6200SE PCI-E graphics card and 3.4GHz P4. Oh, and before anyone says it... the board is supposed to support upto 4GB of RAM.

Cheers.

When they say '4GB' they probably mean '32 bit capacity'

I dont know how new this board is, but somewhere in that BIOS there must be some sort of feature to enable 64bit OS.

Even though you re-set the BIOS to its defaults, usually memory mapping wasnt set by default in older boards. If i were you i'd go through every possible menu/option in the BIOS and looking to the right and usually it gives you a description of what that feature does, until you find something which mentions 64 bit.

ps The graphics card specs etc dont really affect this.

EDIT if you can take any pics of the BIOS from your phone and upload them into this thread (dont ask me how to though), i dont mind helping you look.
