Windows 7: Memory reserved after using nomemristrict in GTA4

Memory reserved after using nomemristrict in GTA4

Hi guys.

windows says 2GB is in hardware reserve and autocad says my HD4870 has 2879MB of memory. all this happened after i used a nomemrestrict crack in GTA4 which allows the game to use system memory i believe. dont ask me why, i was curious.

I have searched far and wide for an answer. I'am definitely on 64bit W7 Pro, and using latest hardwares(i7, gigabyte UD5, 1600MHZ DDR3 and HD4870 1GB). I have also tried unticking the maxboot memory in msconfig.

there is no memory remap option in the bios and i have flashed it many times. I have also reinstalled windows and formatted my HDD. but still only 4GB is usable.

Anyone can help? I really do need the memory. I use highend 3d software and work with large PDS files at times simultaneously.


thanks


[EDIT] answer on page 2. Wasnt anything software or setting or bios after all. Faulty motherboard RAM slots

And this only occurred after using the -nomemrestrict cmd line switch? Strange.

I assume when you formatted you also wiped GTA IV and all it's settings?

Also, you didn't re-use the cmd line switch after a fresh installation?

In MSCONFIG, try unticking both max memory and no. of processors.

yeh formatted everything and have not installed GTA4 or reuse the cmdline switch.

both are unticked as is the default.

have even tried putting the DIMMs in different slots. but no difference.

also, strangely CPUz shows the dimms as dual channel even thought it recognises 3 of them and in the right slots.

Maybe check your mobo manual to see if you are possibly running an unsupported memory config. Although you had everything running well before the nomemrestrict.....
Have you done a memtest?

FYI - The 'nomemrestrict' just means that you can push all the settings as far as they go without the proper amount of memory held on a Graphics card (Hence why when you push high enough it goes red). Its a good idea if you want to see what the game looks like with everything on high, but it really does lag when you play for longer or are in a busy area with lots going on.

As far as the issue, new to me as i never had this problem.

yep, nothing came up with mem test.

-norestriction
-nomemrestrict
-availablevidmem "x"
-percentvidmem "x"

I think i used 250% or something for the percentvidmem. which gives the HD4870 2709GB of ram as seen in the configuration page of autocad.

I should also mention my previous card was HD3650 which used virtual memory. I performed the 'trick' on that card and it carried over when i upgraded to the HD4870.

But i thought this would only apply in the game. somehow it affects the whole operating system.

Even POST only sees 4GB of ram.

Macpod,
I am not a gamer but i think in order to undo this norestriction patch, you need to erase what is written in the file 'commandline.txt' located on 'GTAIV' main folder. This will rescue the known graphics restriction.
Pl. correct me if i am wrong. Since you use this game and crack you'll probably know better.
Hmmmm.....but you say you dont have GTA any longer.

yeh. i have formatted and reinstalled a fresh copy of windows 7. there is no GTA4 or the commandline on the computer.

I have even flashed my bios. should i take out the battery on the motherboard? would that do anything?
