I recently upgraded my computer for the first time in 5 years. It's incredibly budget driven, as I have a newborn at home.

New System
Processor: AMD A10 5800k
Mobo: ASRock FM2A75M-DGS
Memory: Gskill 8gb PC1600
Graphics: Onboard Radeon HD 7600D (Set to 2gb)

Old System
AMD Athlon X2 6000 (3 ghz dual core)
Mobo: Dell crap
Memory: 3gb
Graphics: nVidia GeForce 8600GT 128mb


After getting everything put together and installing Windows 7 64 bit, my graphic performance seems to be worse than my old system. I play EVE Online, and with only one client logged in, I am only getting 25-28 fps at the lowest video settings and my old system produced 30-35 with the same settings.

I know the onboard video isn't ideal for gaming, but I assumed it would be better than a 5 year old graphics card, so I have to assume there is a setting somewhere that I've missed. I've spent the past couple days searching the internet for anyone with similar problems, but everyone seems to be raving about the A10, so I'm at a loss. Any help would be appreciated.

 
Solution
Okay.
http://www.pcworld.com/article/2010666/amd-announces-trinity-apus-superb-graphics-improved-cpu.html

says:
"When adding a high-end graphics card, the internal graphics core is disabled."

So it appears there are TWO ways to get better graphics:

#1. add a second graphics card nearly IDENTICAL to the APU's GPU (2xcrossfire basically)

#2. add a BETTER graphics card, which apparently disables the onboard GPU (I guess automatically).

Anyway, I don't want to hog this thread too much and thanks for pointing out my mistake that the GPU can't be disabled on some APU's.
 
Just thought I'd share my experience in case someone else comes across this thread, as it really helped me out.

A10-5800k
Biostar Hi-Fi A85W MB
8GB Patriot Viper 3 DDR3 1600

I had pretty much the same problems as Charlemagne99 and konferge with the A10-5800k.

When I first put the system together and installed Windows 7...drivers...e.t.c., I ran the WEI, and was shocked by such low graphics scores.

WEI 3D scores Aero: 4.7 and Gaming: 6.4

3DMark 06: 4706

Also this "quad core processor" seemed awfully slow, and down right sluggish.
My old laptop with a Core2Duo 2.0Ghz seemed much snappier than the A10.

I also had the system lock up on me a couple of times, and had to hard reset.

I installed Arma 2 OA, and ran the benchmark 01. The A10 with its 7660d scored an average of 39fps. This seemed kind of low to me, but being my first APU build, I assumed it was an acceptable score.

I was starting to think that all the hype about these new Trinity APU's was just made up.

Then I came across this post, and fired up GPUZ...and sure enough the bus width was 64bit, and memory speed at 100mhz.

Thinking I received a bummed A10 too, I jumped the gun, and filled out an RMA on the Eggs site:)

After re-reading this thread, the part where konferge talked about messing with his memory timings in the bios caught my eye. Memtest passed with flying colors. I ran CPU-Z to check if my timings were right...and they looked fine. But I noticed that my memory, (2 sticks) was only running in Single channel mode. I popped the case apart, and tried the memory in different slots and sure enough Dual channel.

The manual that came with my motherboard was poorly documented...especially the memory diagram.
The whole time I had one stick in the wrong slot, which was somehow messing up the performance of the A10, both CPU and IGP side.

With this thing running properly, I am finally impressed with the performance.

Scores with memory running correctly in Dual channel:

WEI Aero: 6.8
WEI 3D Graphics: 6.8
3DMark 06: 8752
Arma 2 OA: 55 avg fps
 



Thanks for posting. I think you are definitely correct here. When I originally had my issues with the A10-5800K I was only using one DIMM of 8gb. At the same time I did an rma for the APU I also got new memory with a dual channel kit with 4gb X 2 at 1866 mhz. The first DIMM was 1333 and I had read that is was advisable to get faster memory. This does appear to be the issue. With the GPU component of the APU really dependent on memory bandwidth for performance it really needs two DIMMS in dual channels to get the best performance. Great pick up.
 
Solution
Well maybe that is the problem, as I am running a single DDR3 memory stick as well. I haven't RMA'd my processor yet as I haven't been able to take my computer down. So I'll order another stick of memory and see if that fixes it before RMA'ing it.
 


I wouldn't be surprised if another stick does the trick. Let us know what happens...and good luck Ken. :)
 
Yup, adding another stick of memory seems to have fixed it. 3DMark scores are on par with other benchmarks, EVE online hits 40-45 fps at max settings, and the WEI for graphics jumped from 4.8 to 6.1
