Solved How to increase dedicated graphics

HP Pavilion dv9310us

Specs: Vista Home Premium, AMD Turion 64 x2 Mobile T


Hi All, Can anyone tell me how to increased the amount of dedicated graphics memory on my HP dv9310us laptop? It has an AMD Turion 64 x2 and an Nvidia GeForce Go 6150 integrated graphics card with only 64 MB of dedicated memory and 287MB of total available graphics memory. Why Hp would even sale a computer running Vista with only 64MB of graphics memory doesn't make since because on their site they recommend at least 128MB but 256MB is best. I read somewhere that you could increase it in the BIOS. Is that right? By the way there is an upgrade on the BIOS on the HP site but I don't know if I need to do that or not. Would it help?
Thanks for any help that anyone can give me.

Ooops I goofed on that one. I got the two mixed up last night. It was late. :)

Jam is correct. Unlike video shared memory you can't change dedicated memory.

Unlike fully shared video memory where you can adjust the amount of memory being used towards your IGP, like I have on my laptrop, dedicated/turbocache IGP's are automaticly controlled. If it needs more then 64mb of dedicated video ram then it will automaticly dip into your system ram.

But seriously why would you want 287mb of ram being shared all the time on a gpu not meant for games or graphic rendering? You got so many other factors to deal with on that gpu that make it weak. Not utilizing 287mb all the time and pointless and should be your least concern.

well you have pretty much the same problem that I do. I dont have a dedicated card. But to have vista run at optimal you are going to atleast have 2 gigs of ram. I have a dv9205us and it doesn't have a dedicated graphics card but since hp locks there bios you wont be able to increase the available memory.

You're going to have to do a bios update in order to get the whole 128mb of shared video ram or more. I had to do the exact same thing on my Gateway MX6438 laptop. It was only showing 64mb of shared video ram on my ATI X200m for the longest time. I couldn't increase it to 128mb in the ATI driver settings even with the newest drivers from ATI because it would always automaticly reset back to 64mb as soon as I hit 'ok'. Nore could I increase it in the Bios, because there isn't an option that you can change to increase the shared video ram volume. So I had to update the Bios which finally gave me the whole 128mb of shared video ram.

"Can anyone tell me how to increased the amount of dedicated graphics memory on my HP dv9310us laptop?"

I thought I replied to this earlier...did some responses get deleted?

The keyword in the above question is dedicated. The amount of "dedicated" RAM is 64MB. It is physical memory on the motherboard, NOT shared system memory, therefore it can not be changed.

However, the Geforce Go 6150 uses "turbocache technology" to add system memory to the 64MB of dedicated memory on an as-needed basis.

Your system has "287MB of total available graphics memory" which means that under full graphics load, it will add 223MB of system memory to the 64MB dedicated. In theory, it's like having a video card with 287MB memory.

"TurboCache technology balances overall system bandwidth utilization during rendering by intelligently distributing the load between local graphics memory and system memory."
