New Pc Low FPS issues (3 sessions)

[Otlecs]

32-bit OS only recognises 3.2GB Ram, and not 4GB.

I agree with everything you've said, and am convinced it's the "available memory problem" I mentioned in my first response, but I always talk "around" 4GB because people tend to get very picky otherwise!

For example, my wife's XP32 box reports - and uses - 3.7GB with her 256Mb graphics card. My Vista32 box reports 3.2GB. My Vista32 box with 2x1GB graphics cards reported something less than 2GB before I upgraded to Vista64.

So, yes, it's something less than 4GB, but I avoided specific figures because it does actually vary, and it's even more confusing since Vista SP1 which correctly identifies and reports 4GB of installed memory in its 32 bit editions, whilst only actually using something less than that!

:wacko:

This is not exactly accurate.

32 bit windows OS's can address exactly 4GB of memory space. EVERY DEVICE takes from that. Sound card, bios, ata controller, sata controller, usb controller, etc etc etc.

On average you will end up with 3.2-3.4gb of ram addressable. Video memory has to be addressed as well, so stacking two 1gb cards into a 32bit system would have a negative impact as discussed here.

What is the wattage of your power supply?

Only reason I ask is due to a similar issue I am having with Low FPS at times. Correct me if I am wrong, but I have heard this may be due to having an inadequate power supply. Just trying to compare issues here to maybe help you and myself out at the same time. :huh:

Anyone know of a way to see what devices are taking up addressable space in the 32 bit os's? I'm thinking there has to be a way to reclaim some of that space by disabling features in the bios such as raid controllers, on board sound, etc. On my single video card XP 32 installation i'm running into only 2.8g addressable memory which means devices are taking up 1.2g. This seems like an aweful lot when I only have a 512mb video card.

Probably depends on your BIOS but in mine (its an Award) it shows installed memory as well as usable memory.

- I have a 750watt power supply. Hope thats more the sufficient.

I have loaded Vista 64 and im not seeing a huge difference so far although I have not done all my test scenarios.

So far using both video cards i am getting 15fps Main and 8-12 on Both alts on 2nd screen and card.

I will try this with one card later today and report back just ran out of time prior to work. Im curious if there are any settings or known issues with nvidia forceware versions I should know about. Just sucks that twice the memory non-SLI wouldnt give slightly better results even. Another thing is the amount of Mods I have. I will try killing them as well.

Thx for all the help guys.

I believe you are wrong there. From my own experience of bad power supplys the only thing that occured was random crashes, simply because the supply couldn't give me enough power. It doesn't affect framerate at all.

Current Verdict:

-Vista 64bit and dual monitors
-Using both video cards
-changed around a few mods so running about half of what I was.
-Made a change to config.wtf (Was at SET coresDetected "1", therefore processAffinityMask did not exist.)
Changed: SET coresDetected "4"
SET processAffinityMask = "15"
================================================== ========
Currently getting up to 75FPS Main screen 1 session of Wow
================================================== ========
3 Sessions:
Main full screen 36FPS, 2nd Screen both sessions 15-25 FPS

MUCH BETTER!!!

Thanks to all
