I'm not sure about that one because the gtx 670 ftw uses the same pcb as the gtx 680 so there may be compatability issues...I have heard of alot of people flashing reference evga gtx 670's to the EVGA gtx 670 SC model. Have you tried that?,if you have and mentioned it already in this post sorry for asking it.

Hopefully someone with more knowledge than me on this can help.

Here is a bios for the GTX 670 SC model that may help. http://www.techpowerup.com/vgabios/120741/EVGA.GTX670.2048.120415.html

Nah I just modded the already modded bios I was using to further increase the power target but to no avail. Card gets stuck around the 1300 mark when I overclock the memory. If I take the VRAM OC off it will ocassionally boost up the 1359MHz that I want it to run but only in bursts of half a second or so. Seems it also just won't sustain the 1,21V Vcore at max OC because I'm seeing drops as low as 1,150V at times, and I'm at a loss why. Temperatures are below 55 degrees at all times. Could it be the stock boards' VRM's are just insufficient?

What annoys me is that the card is rock solid running 1300MHz even with less than stock voltage... It'd be a nice clock to settle for but it's just that I should be able to get way more out of it, and something won't let me mad.gif

Saw your earlier question, yes you can flash FTW vBIOS to your reference SC board - but I doubt it would help because you will still be restricted by the 6+6 which gives you a whopping 225W max. If you've modded your current vBIOS using common tools around I doubt you've raised the card limit which is 200W - so that's probably what you're hitting at the moment.

I can see on my system that both of my cards are hitting 200W at only slightly over 1200Mhz + 3500 for RAM in 3DMark11 (no downclocks though, it's just at the region now). For your clocks I have no doubt that you're banging that ceiling.

I see! Completely forgot about the 6 + 6 pin restriciton. And that leaves me with no other options but hardmodding it. Since I'm working on an ITX build I'm restricted to using the short PCB, so this is what I'll be settling for then. It's still a fine card. Maybe I should try undervolting it biggrin.gif

Sounds like youre running 170w 100% board power target, but sliding the slider up to 133% (1.33 x 170w = 226w) is doing nothing. Doesnt really do anything on mine either, not sure if it even works. What does work is re-targetting your 100% board power to 225w. The reason overclocking your ram makes the core throttle is almost certainly because ram draws a bit of power - going from +0 to +900 on mine adds another 10% TDP to the power draw and I was pulling close to 270w per card at that time which means the mem OC was pulling another 27w or so.

What bios are you running, a stock EVGA 670 vanilla bios? Can you upload it?

As for flashing FTW etc onto your card, depends, 4gb bios to 2gb card not advisable. 2gb to 2gn card of same brand probably OK. No guarantees though. Cross flashing different manuafacturers bios onto cards is where you can really run into trouble and brick your card, but other times it works out. Its always best to mod your own cards bios though.




edit - hang on. 100% board power for a 670 is 140w........so 122% slider *would* be in theory 170w which isnt much (its stock target for a 680). Might need to adjust both 100% board power and max board power targets. How strong is the reference 670 VRM? I wouldnt think too strong based on nvidias designs in the past.



Here, try this.Vanilla EVGA 670 modded to 200w 100% board power and 225w max board power. Leave your power slider at 100% and see if its any better. Clocks are stock with boost limit rasied to 1359 so it should hit that now without overclocking in software, fan is 20% min 100% max. voltage is 1.212v. Use this at your own risk of course, its pushing more than your card was made to do.

BIOS REMOVED THINK THE FILE BEING 96KB WAS NO GOOD


edit 2 - change file type from text back to .rom and open with a program (KGB bios editor, etc to verify its ok before flashing. I changed it back and forth a couple times on my pc and its fine, just cant upload roms here).

I have no idea if this is due to the program removing it or wether something about the bios itself removes it as my FTW bios throttles downward with temps over 70 but using the hydro copper bios on my ftw card this does not happen..

So you're saying you were able to flash your HC BIOS on your FTW? Then that's possible for all 670s?
