gpu-z misread??

overclocking101 · Dec 5, 2010, 08:46 PM

ok so ever since going dual 5770's i have been getting a 1.000v core voltage. I modified my biuos to ONLY run 1.125v yet in gpu-z i still get a core reading of 1.00v and when I change voltage in afterburner it still shows 1.00v in gpu-z though afterburner reports it correct. i change to it to 1.25v in afterburner and the core to 1000mhz and it runs bench stable yet gpu-z reads 1000mhz at 1.00v. it has to bhe a gpu-z misread. if any info is needed let me know, maybe this can get worked on or something??

which 5770 model? what VRM does it use?

I actually have the same issue. My VDDC is reported as 1.000v regardless of load. Card is a somewhat reference XFX HD 5770 v2 (USA) with a 3 phase analog VRM (I believe), 1 crossfire finger and original full coverage shroud cooler. Exact model number is HD-577A-ZN ver: C.1 on the box.
