Soon Mr. Moon will be shining bright so the best day ever will last all night.
Hi Goons,

I have been having crashing issues with Dota 2 since upgrading my RAM from 2gb total (1gb sticks) to 4gb total (2gb sticks). I'm not sure if RAM is the issue, since the game was just patched. However, when I looked at my system information, I noticed that:

Total Physical Memory is 3.37 GB
Available Physical Memory is 919 MB

This seems like a big problem to me. What could be the cause of it? Or is it not a problem at all? I don't know anything about computer hardware, and when I purchased the RAM I just looked up my computer on crucial.com, went to Newegg.com, and purchased an approximate match for what crucial.com suggested. Maybe I should have just ponied up the extra $30 to get the crucial.com memory kit.

Thanks for your help with this.

If you're having problems you're either holding the phone wrong or you have tiny girl hands.
Install a 64bit os

It's true that I am using Vista 32-bit. However, shouldn't I be able to access about 3gb of the memory?

hello :)
Your ram is just being used, cached, or reserved when you look at system info. Even using 1 browser with 3 tabs I'm "using" 3 gb of ram, out of 4 on this laptop. A lot of that will free up if something really needs the ram.

The problem here is what don larpe said. Use a 64 bit OS

You are "seeing" 3 gb of ram according to what you posted. Probably crashing because you're using trying to use half a stick of ram, and its some memory extension workaround thing too that might add even more flakiness. woops I thought 32 bit could only recognize 2gb, was confusing memory limit extensions (3gb) with capacity. Still, 64 bit lol

Your video card's ram is included in the pool you have available. Also install a 64 bit OS.

Available memory is your total memory minus the amount in use. Use the task manager to figure out what is consuming the most memory.

Hes probably referring to usable memory in system control panel.

This is a common but untrue myth, video RAM is not directly addressable and does not cut into available RAM directly. There is some amount of RAM used up by all hardware device mappings including the video card, but this is a fixed amount tied to the specific chipset you're using and won't change when you change the amount of video card RAM you use. Can be anywhere from 500MB to 1GB on most machines nowadays.

Also to all those saying just install a 64 bit os, that won't always fix the problem because I also have the same issue.

It sometimes depends on your motherboard & BIOS too. I've had a machine from 2007 that would only read ~3 Gb of memory even after installing 64-bit Windows 7 until a BIOS update.

Check your bios for a memory remap option.

We had the same problem with some dumb HP laptops at work. 4GB of ram, less than 1GB usable. Our solution? send the laptops back and get lenovos because HP support told us to use the reinstall disc to revert to the factory image.

Thanks buddy, good advice on my $1500 enterprise laptop.

I've seen that happen with faulty DIMMs. Sometimes reseating the DIMM helps, other times it just keeps happening and what's going on is that the memory is detected but it never is actually used.

I think this blog post may help shed light on what is going on:

And like other respondents have said, Available memory is what you have left of the total amount after various Windows processes use memory.

Does your CPU/Mobo have an integrated GPU? Have you tried disabling it in the BIOS? Sometimes they will reserve system memory even though nothing in the OS is reporting it.

It does not, but I am pretty sure it the faulty dimms or my MB is hosed.
