364425 2005-06-16 16:40:00 I just finshed building a new system. I have a Radeon X850 PE graphics board in it and 4gb of ram. The problem is the graphics board seems to be taking one and a quarter gigs of it. But there don't seem to be any options to change it in the bios. If I reset the bios and then enter the bios before the operating system boots up the gfx board only take 256 megs of ram. But if I leave the bios and restart the system it will be back to taking 1.25gb. Any one know anything about this? Ittiz (8366)
364426 2005-06-16 21:51:00 A PCI-Express graphics card shouldn't share any RAM from the system as they all have their own RAM onboard.
Something is not right!
Have you tried running the PC with only 1GB of RAM?
What about running a memtest to see if the RAM is faulty?
Have you got another graphics card you can try?

364427 2005-06-16 22:05:00 I guess you mean its reporting the card has 256 or 1.5 of ram onboard when the PC starts?
I'd say the MB is reporting it incorrectly. Is it new? What version of BIOS is it using?

364428 2005-06-17 04:12:00 I have tried it with one and two sticks of ram. In both cases none of the memory is taken. I have also used a different graphics card (an old 3dfx Voodoo). When that card was running only 512 megs of ram were taken. I read at the microsoft web page that windows xp will automatically make anything amount of ram above 2 gigs unavailable for normal programs, but I also tried everything with a linux slax disk. With the same result. Ittiz (8366)
364429 2005-06-17 04:28:00 well first thing is how/where are you seeing thats its taking the ram ?

what motherboard do you have ?

364430 2005-06-17 04:48:00 I see it in the bios and start up screen. I have a DFI lan Party SLI-DR for a motherboard. Also something of note when I put empire earth II in and looked at the specs it saw for the graphics on my machine. It said it had 512 megs of video memory and 512 megs of AGP memory. Neither of which make sense since the card has 256 megs of video memory and it's not an AGP card it's a PCI-Express! So that really makes me think it's related to the graphics card. Also the fact that the amount of missing memory changes when I have a differnt graphics board in. Ittiz (8366)
364431 2005-06-17 05:05:00 first of all the graphics board dosn't take ram from the system.

i suspect you have memory problems.

what type, size, single sided, dual sided etc ram do you have installed?

i wouldn't bother with what the games id things as..most get it wrong.

what bios ver do you have? i see there is an update .... "Enhanced memory compatibility"

364432 2005-06-17 05:12:00 Well I know the memory isn't damaged. I tried each one by itself works fine. They are double sided ram sticks DDR400. I'll look for the bios update. could fix the problem I guess. I really do think this is caused by the bios since it does it regardless of operating system andf regardess of which ram sticks I use.

364433 2005-06-17 05:14:00 I suspect that you have problems with programmes. Programmes which report memory availability. :D The numeric range of a signed 32 bit integer is "+/- 2GB". Your 4 GB is likely to be confusing the programme. It's only very recently that memory in such quantity has been affordable. So it's very probable that programmes which have been around for a while will fall over or produce "odd" results. Graham L (2)
364434 2005-06-17 05:59:00 I said earlier the BIOS is probably reporting incorrectly. Update it.
Ignore what games say. I have one that when I ran its PC Specs test said my CPU is too slow - its said I had -2150mhz. Hahhaha. Game requires 450mhz CPU. Mine is an AMD 3500+. Oh and the game runs fine BTW.
