If you have /PME enabled this should enable PAT and PAE if not already. Sometimes you have to edit the boot.ini to tell windows to use the features your board and memory support. Many features are disabled for compatability reasons etc. You may also need a pro version, or ultimate version OS.
Which should allow more then 4096mb per drive to be used as windows "virtual memory. "
If you have windows virtual memory on , with all drives. and more then 2gb for each. And you still get this issue. It's a bug. You should contact the game's support as well. Share what they say, i bet there are other people who have gotten this.
Another posibility, is the game is using more memory then is available and exceeds the limits of what you have told windows to allocate. With /pme or PAE enabled system...You can Dedicate multiple hard drives or SSD entirely to virtual memory (page files) which are used when gmem and pmem are used up. "vram" is used by the gfx cards, and shares page files and physical system memory. Which is set by windows, and is found in the registry.
Here is my boot.ini section where i added my tags for example. Google anything you don't solidly understand. It can damage your pc if it's not supported. some win7+ versions may not need these.
This is used on a dell gx270.bios a07 I also used reg tweaks to remove the vRAM limits and set aside 60 gigs.
You must setup virtual memory settings to support these settings. Or it will bluescreen, and give a similar error in games etc. windows sets aside "vRAM" via registry, physical memory allocations to share to all detected GPUS via registry settings,
this is what is called "vRAM" Microsoft doesn't like people going over 1 gig per gpu. But if you find the proper tweaks. You can disable these limits. Doing so will open up the use of your HD's and pagefiles for video memory a lot more. Default is 64-128MB and is preset by microsoft during initial oem setup. Depending on detected HW
multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect /maxmem 60000 /HT /PAE /PAT /SLI /sla /RSS /PME /cuda /pse36 /ssr /numproc=2
Currently my page files on 4 raided HD's one is 40gb dedicated 5400 UDMA 133 & 3 uDMA 100's @7200rpm. xD the 133 outperforms the others despite the slower spindle speed. . all together equal 64GIGS for page files/virtual memory alone. And windows system manager etc acknowledges the allocations
On a system that is said to not be able to use more then 3.5gb...i've witnessed more then 6 gigs being used at one time. I have 4 256mb ddr3200 in dual ch. There is only 1.22gigs of physical memory xD and 288MB on the 2 video cards. Which is also shared with the system. This would be the same with any integrated gfx, either on-chip or on-board.
I have also tested various HD setups and usb 2.0 flash drives. If your main OS hard drive is slow. It is benfitical to put the page files of the largest size. on the fastest drives. Adding the SSD's also improved performance and allows the freeing up of physical memory much faster, even during requests for more memory. Not sure why, regardless of it's benched speeds and interface. But 2.0+ definately speeds up various things. It is noticeable drain without the SSD's used as page files.
Because i removed the "vRAM" caps / limitations. I had to specify a /maxmem. to stop crashes from the system requesting more then was allocated. Particularly after i noticed via monitoring software that when overclocked, to 3.42 the system was able to request 46GIGs under various web browser games, gameing in general, and boinc situations. But would always crash if i did not have the virtual memory and other tweaks in place. This works. But does increase the heat and load on cpu and chipset. I had to make a bigger heatsink and apply thermal paste to the chipset's chips haha xD
Good luck hope you find a solution.
