Hi Guys, Apologies if something like this already exists - first and foremost, this is not about how to undervolt, but rather a strange problem I'm facing after undervolting. I have 2 MSI R9 280x's (mining rig - who games with these things anyway ? - to successfully (well not really sucessful) undervolt it I had to load another bios - I went from 015.040.000.003.003435 to 015.040.000.000.003435 - from there I undervolted the card to 0.956v - everything seems stable (running for 24 hours on both cards). GPU-Z is showing the correct voltage however my problem is the wattage meter I have in the socket reads roughly the same watts before the change. I was hitting around 650watts and its still around 650watts - what's going on?? My setup as follows: MB: Gigabyte 990FXA-UD3 AMD 990FX (Socket AM3+) DDR3 Motherboard Proc: AMD FX-8350 4GHz Socket AM3+ 8MB Cache Retail Boxed Processor RAM: 4GB G.Skill DDR3 PC3-12800 1600MHz Ripjaw Series (9-9-9-24) Dual Channel kit for Intel P55 GFX: As described above x2 PSU: Corsair Professional Digital AX860i Fully Modular 80 PLUS Platinum 860W PSU OS: Windows 7 64bit Ultimate I would have thought I would be nearer the 500watt mark, even 550watts would be better ... Anyhow, any help would be appreciated, I'm using Energenie Power Meter to check my power output. If I've missed any important details, let me know. Thank you for your help!
