Dell M4600 Overclocking- Quick

Alrighty issues resolved.

Current Overclocks:
Core clock: 875
Memory: 1150
VDDC: 1.1v (cannot find a way to raise it yet, not sure if I would want to either though).

Ran stable for 20 minutes. I will benchmark now, and post results.
I believe I still got overhead for memory overclock. (shame about having only a 128 bit bus width).

Temperatures are very very good at 76c max after 20 minutes in a fairly confined space.

Tools:
Gpu-Z 0.6.2
MSI Afterburner 2.2.1
AMD Catalyst Control: 8.911.3.4
HWMonitor: 1.19

 

You either boosting the voltage past 1.1VDDC, to achieve those overclocking? I did a post not long ago about overclocking, I assume you used MSI Afterburner? For me that application doesn't work even with the "I Agree" with modifying .cfg

 

retesting. Sorry.

 

Okay something is up. Even with the higher clock speeds I am starting to see little gains in performance (from 1100 to 1250 core to 1050 memory to 1150 memory I saw barely a 2-3 fps jump) It's possible I've hit my adapter's power limit or the like.

Going to get 3dmark and confirm results. I suspect something fishy is going on.

 

Yeah i am getting very poor performance in 3dmark 11.
Issue was with powerplay set up in "low performance".

I set it to high performance. Doing benchmark again.

 

Just to let you know, the GPU-Z detection of clocks on it's Graphic card display isn't reliable. To check what clock and memory speed use the sensors, since the GPU ignore setted clocks. It's a powerplay thing....

I've notice you changed your previous clock rate 1000MHz and 1050MHz... Don't trust the stats in the graphic card details, they can be easily change.... As the GPU just ignores it anyway! It only chooses it in the correct conditions.

 

I had poweplay at Maximum battery savings, so it let me overclock to whatever. Scores of course were not congruent since powerplay limited the TDP of the video card, hence why I reported that the performance seemed tohit a dead end and I was seeing little performance gains.

I went ahead and put Powerplay to maximum performance, which freed the TDP.
Overclocks at the moment (875 core/1100 memory) are stable and congruent with 3dmark benchmarks (1805~ 3dmark11 720p performance setting).

I am going to push memory to the max today.

Gpu-Z is very accurate as it uses the sensors on the GPU just as AMD catalyst center.

 

I didn't say GPU-Z sensor was inaccurate, I said use it than using the GPU description tab. As it's totally useless for seeing the actual clock speed than it's defaults. As you provided a GPU-Z image, and thought you not using the sensors. As powerplay just clearly just ignore them, which is why I just disable PowerPlay cause it cannot lower the clock properly.

 

This may be why MSI afterburner is not working for you.

Download HW monitor and check the VDCC for the M5950.
When I disabled PowerPlay the VDCC was reduced to .9v and overclocking as pretty much useless.
Powerplay MUST be enabled with Max peformance for overclocking to work properly.

GPU-Z has actual clocks hence why I use it.

 

Not sure what you mean, I got every thing off. PowerPlay and AMd catalyst center removed. Yet I can control Voltage and Clocks, if you have read my topic...
