I have just put another 512mb of memory in my pc so now it has two sticks of 512mb of pc2700. In sys info it says that i have a total physical memory of 512mb but in system properties it says that i have 256mb, which are both false. Can anyone help tell me why and how to correct this please.

Many mobo's do not support that much RAM, unless VERY new.

Check with your motherboard manufacturer's website (or if a name brand, check the suppliers website) for a BIOS update and confirm the mobo supports oer a gig of ram.

When i put the first stick of mem in it came up with 256 when it should have been 512. my motherboard is a Gigabyte k7 triton 400 ga-7va and it says supports upto 3.0gb ddr. With thanks

This is a reasonably recent motherboard.

Are you sure that you have the correct DIMMs?

2.5 volt DDR.

If you ended up with dual channel, ECC, or registered DIMMs, that might be the problem.

My only other idea is to inspect the DIMM sockets for a dirty or bent pin.

Even a cable running underneath the DIMM sockets could be the source of your problem.

Excuse me... May i post my question here? i don't know where to. well thanks. my issue is this.

I have a 10 gig hard disk but my motherboard or bios can't handle this large disk access. is there any possible way to access the maximum capacity of this hard disk?

thanks in advance.

Generally speaking, the best place to pose technical questions is in the Technical Q&A section.

One BIG advantage of posting technical questions there is that you get an email when an answer is posted.

My best recommendation for large hard drive detection is to install a PCI IDE controller card.
In addition to recognizing the full capacity of your hard drive, most controller cards also have a faster data transfer rate than your older on board IDE controller.

If you don't wish to invest $30 (US), there are 2 free options:

1. check with the motherboard manufacture for a BIOS update.
Do not flash your BIOS unless you are positive that the update is the correct update for your motherboard, AND the update specifically adds large hard drive detection.

2. Download and use the drive setup software from the hard drive manufacture.
Most manufactures offer BIOS overlay software that allows you to fool the BIOS into using the full capacity of the drive.

Is to let The Chas help you out now.
I just offered the basics, Chas is one of the top hardware guru's here, not I. You are in good hands now, :)

Good luck with it, keep us posted on what happens please!
