Ram Allocation to APU WITHOUT BIOS

[jacobweaver800]

I have an HP desktop with an AMD A8-5500 quad core APU, the graphics are fairly decent, but I find I am VRam limited in most games I play. I've been through the BIOS multiple times and can't find any way to allocate more system memory to the APU, I'm stuck at 512mb's. I have 8gb's, so I can easily spare a few gigabytes to the APU, I'm not looking for a registry hack because those only change how much VRam applications think you have, not how much you actually have. So my question is, is there some sort of software or something in AMD overdrive or the Radeon settings to allocate more VRam to my APU or am I stuck at 512mb's? HP locks the BIOS and removes advanced settings to do this and it is very annoying.

There's no way to do it outside the bios. That's not controlled by the OS. There's a forum where people mod bios files for these kind of situations but I'm not sure that they still work with recent computers as most of them are signed by HP with their own encryption keys. You'd have better luck just getting a dedicated GPU instead as you won't find any software workaround unless HP changes its bios.

My 16x PCI-E slot is dead, so a GPU upgrade for that PC is a no go.

Well then there's nothing else left, there's really no point in doing anything else to that pc as it won't really improve much. Sorry if it wasn't what you expected, that's how it is with OEM pc's.

Why should you be worried, if vram are full, it would automatically use system. Because you are using apu, they should be little degradation in performance. You can try increase your system memory if you are stilling seeing issues.

That APU isn't fast enough to use even 4gb's of memory. It only has 512mb's and on a non OEM board that can be changed in the BIOS, which is what I want to do. Thx for the responses but I got a new PC about 2 pr 3 weeks ago.

then, i don't think there is much you can do. i know certain game give you error if you don't have a big enough dedicated vram allocation. is that the reason? Increase the allocation also lowers your total available system ram.
