Need help for gaming (increasing V-Ram on the AMD Radeon HD 8670D)

APUs don't have a specific amount of dedicated RAM, that amount is dynamic. If you have few RAM, the video RAM will be small, if you have lots of RAM, the video ram will be big (i think 2GB is the max amount the system can reserve). The amount increase or decreases on demand.

The integrated GPU in the APUs benefit from high speed RAM, what speed is yours? If you have 1333MHz RAM, that may be the problem. Also, if you're in single o dual channel mode.

Yes, "like magic".

If you can, get AMD certified RAM, like this kit: http://pcpartpicker.com/part/amd-memory-r938g2130u1k. An AMD kit may not require a manual configuration.

But, If your motherboard supports XMP profiles, any XMP compatible RAM will do the job. Like this Kit: http://pcpartpicker.com/part/gskill-memory-f317000cl9d8gbsr. This will require a manual configuration in the BIOS, but is very easy to set.

No, you don't need to upgrade your parts with more AMD stuff. The RAM can be from any brand and also the GPU, it can be from nVidia. Do you know what chipset your motherboard has? A55 and A58 chipsets only support AMP (AMD Memory Profiles, AMD certified memory uses this) and not XMP. A75, A78, A85X, A88X chipsets does support both AMP and XMP profiles.

The easiest way to improve your gaming performance, guarantied, is adding a discrete GPU. As i told you, the R7 250X is a cheap and great option, if you can spend a bit more, the R7 260X.

Just with the model i can tell you.

Hello, I am reluctant to find someone with literally the exact problem i have. Same processor ram and everything. If you did happen to find a fix please reply to this so i can know.

Hey Bruno, I know this is an old thread but you seemed to help Dan out and you seem knowledgeable on the topic. I wonder if you could give me some advice? I have:

AMD A10-6700k APU with integrated HD 8670 graphics
16BG RAM @ 2133 speed

I upgraded from a slower cpu and ram, but my graphics are worse now than they were before. I must have a graphics configuration issue as my still graphics are VERY CLEAR, but my games are all choppy video. I don't know what the problem is.

Can you help maybe?

Are you using a dual channel RAM kit?

Have you checked if your RAM is working at the rated speed (2133MHz)? Maybe you need to set the XMP profile manually to make it work at that speed.

What motherboard do you own?

Bruno,
Yes, using dual channel 2x8GB
I have A88XM-A mobo.

I have screenshots of my BIOS, and i also have a CPU-Z screenshot of my memory config. But not sure how to post them here.

Hi Bruno,

Any feedback yet?

What values does CPU-Z show about your system memory?

Try also Aida 64 (it's what i use).

Cpu-z shows:
DRAM Freq 1066.4 MHz
NB Freq 1799.6 MHz
DDR3
16GB
Dual
FSB DRAM: 3:32

What exactly do you want to see from AIDA ? More than this?

From Aida64, i also wanted to see the frequency it registers.

The "report" i showed above is all i see in AIDA re memory. Not sure how to get the "freq" in AIDA

aaaah. i found it:

Something is out of whack. Within the above report it shows both 2133 and 1333.

And CPU-Z shows the JDEC number as 667MHz and the XMP profile as 2133. Is it possible that my mobo does not support something to do with XMP mem profiles?

Ok, i see the problem.

Your RAM is working at default speed 667MHz (1333 MT/s) and you need them to work at rated speed 1066MHz (2133 MT/s).

You need to set the XMP Profile manually in the BIOS.

yeah makes sense. But i don't see any XMP section in the BIOS. Again, it may be possible that my A88XM-A mobo does not support XMP. Is that possible?

Yes, it does. A88X Chipset supports XMP and AMP.

Check in the BIOS if there's a tweaking tab or something like that.
