[PC Load testing software]

OCCT, does load testing, error checking, and also combined load (gpu/cpu).

 

i feel that if your pc handles a couple of hours of OCCT, it will survive anything you can throw at it (apart from physical objects)

[AMD Graphics Detection "Bug"]

Hi there,

 

I have found some "errors" on the graphics tab. (and nowhere else, custom voltage settings get detected perfectly and stuff, so great job!)

 

About my setup:

Windows 8.1 Pro 64-bit

i have 2 sapphire HD 7870's,

one is the ghz edition, running stock at 1000/1200mhz

one is the oc edition, running stock at 1050/1250mhz.

 

Here is what happens for me;

for both cards the performance levels get detected as 1000mhz/1200mhz.

HOWEVER!! the actual GPU clock's (1000/1050) and memory bandwidth is correct, 153,6GB/s for the ghz edition, and 160GB/s for the oc edition.

Speccy does see the difference between the cards.

 

also, the OC edition does not get the bios version, and crossfire is "Disabled", this however might be something with the way the AMD driver works, since the 2nd card is "powered off" when i am not in fullscreen, and crossfire does not work unless I run games fullscreen.

 

I just checked GPU-z, and it does get the bios version of the 2nd card, and also that crossfire is Enabled (or disabled when i disable it in CCC).

 

Now, with gpu-z open, it does get the bios version of the 2nd card. After closing gpu-z, and restarting speccy, it still gives me the bios version of the 2nd card, i will reboot now and report my findings.

 

After rebooting, i again, do not get the bios information on the 2nd card, i suspect gpu-z somehow wakes up the 2nd card to get this information, and after waking the card up, speccy can access the information aswell.

 

I just tried making a new application profile for gpu-z in CCC, and i did not get a warning that i was overwriting an existing profile, so i dont think there is a hidden feature in the driver that wakes it up for gpu-z, but rather it is gpu-z that does something to wake the 2nd card up.

 

I copy pasted the info speccy gives me, I hope this helps you, if you need any more info/testing or stuff, feel free to contact me.

 

Keep up the great work!
