Windows Only Recognising 1.91GB - 4GB Installed

I think I answered it at PCGamer.com:

You're posting this everywhere!

Haha, more likely to get right answers if you post it everywhere. And thanks, I'll look into that then, although I'm still updating to get to the service packs (I'd presumed it'd installed them already).

So I'm being told that the my addressable RAM should normally be between 2.5GB - 3.5GB, depending on how much my graphics card reserves for itself. Potentially, some other hardware might detract minimal amounts from the 4GB maximum also.

So to clarify my problem: when my graphics card is the same as it was before I upgraded, should the amount of addressable RAM not be around the same as it was (3 - 3.5GB), and not the (ridiculous) 1.91GB that it is now?

Per the other Thread:
Memory Usage 65 %
Total Physical 1.92 GB
Available Physical 673 MB
Total Virtual 4.06 GB
Available Virtual 2.40 GB
8.00 GB Dual-Channel DDR3 @ 798MHz (11-11-11-28) (2 x 4GB)

Per this Thread:
Vista Home Premium 32-bit) only lists 1.91GB of the 4GB I have installed

Assuming, you put the 1 of 2 sticks in the correct DIMM slot:
CPU: | blank | 4GB | bank | blank |

Q - What EXACT kit is '798MHz (11-11-11-28)' ?

It's either junky DDR3-1600 or faster or off the charts DDR3-2400.

Q - How much RAM did you set for the SHARED MEMORY in the BIOS (iGPU); DVMT Memory?

I am assuming the MAX of 1759MB!!!

Solution, 9/10 BIOS DVMT Memory -> 128MB. Once you get a 64-bit OS with RAM to burn then have at it, but now use the lowest possible value to the iGPU, and run in d-Mode i.e. connect the Monitor to your HD 5770.

The EXACT kit is this:

By iGPU do you mean the integrated graphics card? Because I've set that to the lowest memory allocation (128MB like you said) already, and there was no difference. (I've also tried disabling the integrated GPU too.)

But I'm pretty sure the only options I have in the BIOS for it are 128MB and 'Auto'. (I assume we're talking about the same thing - if you could talk to me like I'm more of an idiot/child, I would really appreciate it.)

Okay, lets check them all. The following is so everything works, but ALL shared Memory is reduced.

Boot into BIOS:
Page 47 of your manual:
1. Primary Graphics Adapter -> PCI Express (PEG)
2. Onboard VGA Share Memory -> 32MB
3. Render Standby -> Enabled
4. IGD Multi-Monitor -> Enabled
5. DVMT Mode Select -> DVMT Mode

Page 48 of your manual:
6. DVMT Memory -> 128MB

Save & Exit = Yes

Shutdown:
A. Connect the Monitor directly to your HD 5770 via a DVI-D connection
B. For now, use (1) stick both sticks of RAM as below:
CPU: | 4GB | bank | 4GB | blank |
<or>
CPU: | blank | 4GB | bank | 4GB |

Boot into BIOS:
Page 41 of your manual:
Load XMP Setting -> Profile 1

Save & Exit = Yes

/Option, a public beta of Windows 8 64-bit is available. You would have to install it clean and re-install all of your applications. BACKUP DATA FIRST!/

Windows 8 beta (preview) - http://www.tomshardware.com/forum/16-73-windows-consume...

Usually it is from bent CPU pin on the motherboard.

Just to be clear: are you saying I should install one stick of RAM or both?



I literally put it all together a couple of days ago and all of the pins looked fine, but thanks. I'll check soon anyway, just in case.

I made and error and edited above before you posted:

B. For now, use (1) stick both sticks of RAM as below:
CPU: | 4GB | bank | 4GB | blank |
<or>
CPU: | blank | 4GB | bank | 4GB |

Also, if the BIOS settings above fail then (F5) Load Optimized Defaults and add Load XMP Setting -> Profile 1 then Save and Exit = Yes.

OK, RAM is set like this:

CPU: | 4GB | bank | 4GB | blank |

And there are a couple of issues:

Onboard VGA Share Memory isn't an option
DVMT Memory doesn't go below 256MB

I should just hit F5 and do the Load XMP Setting then?

Because you only got Windows Vista 32 bit. It's the only solution for your problem upgrade to Win 7 Home Premium for only $49.00

I think I've made it clear through the course of the thread that the issue is not using all of the RAM I have installed, but rather the fact that it's not going up to (or even near) the max. limit that a 32-bit system has, as it did before I upgraded my system.

OK, I went with defaults and Load XMP Setting -> Profile 1, as a couple of those options you mentioned were missing. Let me know if I should do otherwise.

After the F5 + XMP, what's the story now. As far as other options, make sure ALL SATA ports to be set to AHCI. Run Fix It to set the Start values = 0 (zero); see -> http://support.microsoft.com/kb/922976

I'm done for the night, let me know what's going on...Good Luck!  

Still displaying 1961MB in Task Manager - I'll check the SATA ports in the morning.

Haha, I don't believe it: I was then about to look for those options in the BIOS and call it a night, when a setting called 'Low MMIO' caught my eye, as it was set to 1024MB. Turns out that whatever this is, the 1024MB option is optimised for 64-bit, the other option was 64MB and is for 32-bit systems.

Voila, addressable RAM is now at 2.7GB.

Anyway, thanks for all the help!

Try a RamDisk to see if you ca load the extra 4GB memory to it.

I've also changed the DVMT setting to 256MB as well, which has now put me up over 3GB. Thanks again.

Cool, figured it was you iGPU funnest. Now get yourself a 64-bit OS.

Good Luck!
