Posted December 12, 201212 yr Can't seem to get past 1.216v on this card. Enabled the dip switches but to no avail. Tried several ABX editions but voltage is always stuck at +0.200. Ideas? Drivers, skill?
December 13, 201212 yr Author I tried the 2.10 MOA edition and it gives 1.6v but doesn't apply it. Used a multimeter to confirm. Does all the switches have to be at the ON position?
December 13, 201212 yr Did you switched to LN2 BIOS ? http://www.guru3d.com/miraserver/images/2011/gtx580-lightning/IMG_4122.jpg I didn't have lightning X version , but it should be same as 1.5GB. First double switch from right should boost vGPU and vMem 0.1 Volt, try them. Did you measure voltage with multimeter under gpu load ? Turn all switches On but don't stay on full load for long time. Southerner switch (near PCI-E slot) is for cold-bug , I don't think that should be necessary to be On. (Num 1 = on : -80C , Num 1+2 = on : -180C) http://www.techpowerup.com/reviews/MSI/GTX_580_Lightning_Extreme_Edition/images/dip2_small.jpg
December 13, 201212 yr Author Yes, turned them all on, nothing changed. Max voltage I could get is 1.276v with AUX at +.05. Thanks!
December 13, 201212 yr Did you check while in 3dmode? Enable Force constant voltage, in Afterburner settings.
December 13, 201212 yr Crew Allen to the rescue ! Gamer's wife will be very unhappy again tonite thanks to you
December 14, 201212 yr Author There is an LN² bios on the card, but I get the CB at -75°. I can use the same bios as on the 1.5GB version? Edited December 14, 201212 yr by Gamer
