1. Download the new version of GPU-Z
2. Check your ASIC quality (Right-click on the titlebar of the GPU-Z window and from the popup menu menu select "Read ASIC Quality..."

Post it here.
(There are still some kinks to work out so some may get over 100%)

Here's mine:
Graphics Card: EVGA GTX 580
ASIC Quality: 86.6%

Application Specific Integrated Circuit - quite what the relevance is I've got no idea.

It's an indication of the quality of the ASIC. It can give some indication as to the binning, and ultimately, overclockability of your GPU.

Main reason I made this thread is to see if there is any sort of trend emerging if we get a big enough sample. (Like Lightning cards, or EVGA SC/Classified etc having higher values).

Might also be useful to see how far people have managed to overclock their GPUs.
 
Odd ! OP seems to have the same bug as me ! My card is apparently running PCIE 1.1

@ALXAndy, They've also added a ? symbol next to the PCI-E speed. If you click it there is a render test that will clock up your GPU and this will also show the correct PCI-E version.


I'm thinking it's because the card goes into low power mode or something when not in 3D mode so it's leakage will be greatly decrease. If that's the case then GPU-Z is working it out on the fly, it would be worth trying it again with some 3D running to see if it's different.

I used the render test to load the GPU and then ran the ASIC quality, and it stays the same. Will be interesting to see if Duffman sees any change.
 
It certainly doesn't seem to have any trend with higher numbers = better overclockers. I've tried it on a handful of 4xx cards now and all the good overclockers get upper 50s to low 70s and the average clockers are all in the upper 80s or upwards. Don't have any poor overclockers to hand to try - this is only about half a dozen cards tho so not enough to say that low number = better overclocker.

Yeah. Increasingly, the ASIC quality seems to be unconnected to overclockability. I've noticed on other forums people with EVGA GTX 580 SCs with lower ASIC quality than mine.
 
nothing, i've only overclocked it but got same reading even before i overclocked it.

is your 555m the main gpu or secondary gpu?

mine is the secondary gpu and i have to go in nvida control panel to tell it to use the 555m gpu instead of the intel HD 3000 gpu.

Try the dropdown box at the bottom of GPU-Z. Changing the GPU there worked fine for me on my work laptop which has a sandybridge IGP and an NVIDIA GPU.
