Overclocking 480M (with LP2 benchmark)

Hi everyone. How come I can't find benchmarks for anyone overclocking the 480M? Has everyone gone 5870M?

Am using EVGA Precision. Windows Vista 64. 4GB Ram. 840QM. Evga precision limits the memory to 1440.

Lost planet 2 benchmark, 1920x1080, all max (DX9 - long story).

Stock (425/1200) Test A Scene 1 = 36.3fps
OC (600/1350) Test A Scene 1 = 47.5fps

Not bad if I do say so myself. I don't want to go past 600 core (desktop is only 607). And when I tested memory at 1400 the gpu reset itself almost instantly (wow, didn't know it did that - and I filled my pants). So I think thats me done, I tested in 25mhz increments, but thats my final results. I'll prob run it at 600/1300 (45.8fps) just to ease off it a bit.

Oh and temps at stock were 68/69 degrees under load. OC temps 73/74 degrees. The room temp a toasty 27.5 degrees.

 

Not sure why there aren't many overclocked results. Maybe instead of temps being the issue, it's power.

I would like to participate by comparing with my own results as I use an overclocked radeon HD5870 to 840/1050. I am little by little trying to reach HD5770 clocks to get the performance.

I will download later today the LP2 benchmark.

 

The only thing I've changed is I've now installed Windows 7 (had to put Vista on first as I only have Windows 7 upgrade!).

Stock (425/1200) Test A Scene 1 = 43fps
OC (600/1350) Test A Scene 1 = 53.8fps

Will try DX11 mode when I have more time. I guess at least running DX9 I can compare it with 285M too.

 

This is probably why you don't hear much about the 480M

5870M owners: 100,000
480M owners: 46

It's simply the population difference, 480M isn't in but a few very expensive laptops and just released; 5870 is in many laptops, can be had for cheap, and released in February.

 

@Bink17,
Could you do us a favor? Could you please download and run in background this tool when running the benchmarks (both OC'ed and stock) and then post 2 screenies?
I wonder if latency is present when OC'ing the 480M.
Thanks.

 

At the moment I have it clocked to 525/1350. At 600/1350 it was using an extra 20-25 watts of power and hitting 167w on occasion from my 180w power pack. Idle the laptop draws 95-100w.

This screenshot is the DPC when its overclocked. Do you still want the normal one?

 

Is 600/1350 your core/memory? What is the shader clock?

 

Yep, shader clock is 1200 according to evga precision.

 

No need for the idle one, thank you very much.
Looks like a single 480M is ok! +1 rep for the efforts.

 

It appears it wasn't the memory that was the problem... its the core. With the core at 525, I can push the memory up to 1440 (the max in evga precision for some reason). I assume the core instability is due to the slightly lower core voltage to the desktop version.

So my windows 7 results are looking like:

Stock (425/1200) - 41.3
OC (525/1440) - 51.4

or DX11 (everything high, no AA, dx11 features none - not sure why LOL)

Stock (425/1200) - 49.3
OC (525/1440) - 59.3
