v0.8.2 wrong Die Size & Perfcap Reason missing

[ricoh]

Hi W1zzard,

i've recently bios modded a GTX 285 into a Quadro FX 5800, and noticed there's a difference in reported Die Size:


Google gives me results for both sizes, so which one is correct?

Second thing is the same problem as in this thread: http://www.techpowerup.com/forums/threads/perfcap-reason-not-shown.209506/ , Post #13:

The problem only exists in "Standalone" mode. If I install GPU-Z it's [Perfcap Reason] working.

I had to delete this regkey: HKEY_CURRENT_USER\Software\techPowerUp\GPU-Z
then start GPU-Z and select installation.

Observed in two different systems with GTX 670 and GTX 470, both running Windows 8.1 with latest updates.

Hmm not sure which die size is correct .. using some Googling I think it's 470 mm². Anyone know details?

I'm only finding the GT200b is 470mm²

PCGH has measured these chips without heatspreader:

G80 (90nm): 486,5 mm² (21,7 mm x 22,42 mm)
GT200 (65nm): 606,9 mm² (24,77 mm x 24,5 mm)
GT200b (55n): 497,3 mm² (22,3 mm x 22,3 mm)

Btw W1zzard, do you have any news about the missing PerfCap when GPU-Z isn't installed?

kthxbye

 

[W1zzard]

so it's probably 487 mm² then

haven't had time to check on that perfcap problem

 

[W1zzard]

PerfCap should be fixed in 0.8.3 which I just released

 

[ricoh]

Yes, it's fixed now and working fine, thanks for the update.

It's like a completly new feature for me as i've never "installed" GPU-Z before, and the differently colored bars for Perfcap Reason are great. :thumbsup:

The issue was related to the executable name .... perfcap was only visible when it on "GPU-Z.exe".. since I test locally with that filename I never encountered the problem. Thanks for reporting!
