Well I was doing some stability testing on Crysis/Furmark to accertain the best stable core overclock I could get on my Asus 5870V2. I was using MSI Afterburner for fan control, Asus smartdoctor for voltage and clocking, and GPUZ 4.3 for temp and voltage monitoring.
I noticed some alarming and freakish voltage spikes on the VDDC channel. At first I though this was a display bug but on closer inspection temps really did spike by several degrees due to these spikes.
After a bit of research I came across a few threads discussing this concerning issue. Apparantly MSI Afterburner and GPUZ or any other voltage monitoring programs when operational at the same time cause a software>hardware confliction that spikes the VDDC voltage to exactly 1.65 or 2.05 volts everytime (always this same figure).
Disabling voltage monitoring in Afterburner was enough to stop this conflict for me. Have not had a spike in a good 5 hours of gaming/testing.
Anyone else experianced this issue? I definatly suggest 5 series users keep an eye on this.
