vmanuelgm Posted November 10, 2013 Share Posted November 10, 2013 Try a different program for overclocking. E.g. Nvidia inspector, I had serious issues with MSI AB.What was your memory clock?Everything over 215 in core and 200 in memory will crash in firestrike...

Phot3k Posted November 10, 2013 Share Posted November 10, 2013 Trying to flash your EVGA 780 - SC ACX - 80.10.3A.00.81 - 'OC edition v03' using nvflash in DOS but get a board ID mismatch (something along those lines) even with accepting with yes. Any ideas on the problem? Here is my validation: techPowerUp GPU-Z Validation 59p4v Thanks. Quote Link to comment Share on other sites More sharing options...

DStealth Posted November 10, 2013 Share Posted November 10, 2013 Can we flash 780TI BIOS on reference 780 ? Any info regarding this ? Quote Link to comment Share on other sites More sharing options...
svl7 Posted November 10, 2013 Author Share Posted November 10, 2013 Yes you can, won't work fine though. Quote Link to comment Share on other sites More sharing options...
DStealth Posted November 10, 2013 Share Posted November 10, 2013 Thanks will try though , what issues to expect my biggest concern right now is fan speed with all non-ref BIOS it's lower. With TI should be fine I presume... Edit: Flashed it, but cannot install video driver, any help would be appreciated Quote Link to comment Share on other sites More sharing options...

dureiken Posted November 11, 2013 Share Posted November 11, 2013 Hi thereI have a MSI Gaming 780 Twin Frozr, which bios should I use without problem ?Thanks Quote Link to comment Share on other sites More sharing options...
vmanuelgm Posted November 11, 2013 Share Posted November 11, 2013 As I said yesterday, I tried today with nvidia inspector and the results are better. In sli I can reach (with 1,21v limitation) 1265. In single, I reach 1300 in one of the cards. Here a firestrike in sli @ 1265 and +300 in memory: Here a firestrike in single @ 1300 core and +300 memory (1,21v limitation): Now waiting for an afterburner and a softmod that can unlock voltaje (at least until 1,30v) to go beyond... 2 Quote Link to comment Share on other sites More sharing options...

Crysis1 Posted November 12, 2013 Share Posted November 12, 2013 OC with nvidia inspector is better than Afterburner? Why? I have never tried Quote Link to comment Share on other sites More sharing options...
Crysis1 Posted November 12, 2013 Share Posted November 12, 2013 I got my 780 Lightning 2 Weeks ago, with HYNIX-Memory, stable with my Original LN2 BIOS up to +800 = 3.800 (just testing stability)Maybe I also habe GPU-Stepping B1 - i dont knowSince 2 weeks i am looking for a solution to pass PT-Limit and overclock the GPU more than 1.212vFirst problem: My Lightning does not have the VDDC-NCP4206 voltage controller, so i cant overclock with the puplished Afterburner Tweak. Afterburner says my voltage controler is vddc-CHL8266. Now I find a way with this settings in AB:[settings]CaptureDefaults=0vddc_Generic_Detection = 0vddc_CHL8266_Detection = 46hIt works, but strange: my digital multimeter shows ma 100mv more than I put in Afterburner - ok we will see, i am gonna testingAlso I am looking for a Mod vBios and found in www only one BIOS: Skyn3t in the 780s owners forum.I tried Sky-LN2 BIOS and have following problems:1. By flashing I got this from nvflash:*** WARNING: Overriding the Board ID can be very dangerous. ***Upgrading to an image with the wrong Board ID can render the video cardunusable.Overriding the Board ID is only needed for extreme circumstances.A mismatched Board ID almost always means the wrong firmware image is beingused for the specific video card.Are you sure you want to continue?Type "YES" to confirm (all caps):I closed my eyes an flash: ok, it works, but:2. My Memory crashes at +300 = 3.3023. Overclocking the GPU i habe very strong Vdrops, the voltage is varying from 1.040 to 1.450v, up an down spinningThis BIOS seems to be bad for my Lightning, i read the Sky-BIOS is build for Elpida Memory? @svl7May I try your 780ti BIOS or one of the others 780-BIOS?Best wishes from Germany Quote Link to comment Share on other sites More sharing options...
