Juniordnz, it looks like you may have accidentally posted the same screenshot for both bioses on the last page. Thanks for doing that test btw; it's very curious to see the FE bios producing better results at reduced clocks. I wonder if the difference in measured TDP and VDDC has to do with differences in monitoring circuits within these boards? Ie the two bios interpret the signals differently.

Does anyone have the Gigabyte FE bios? I'd like to try the same thing on my G1 gaming card (25k in firestrike on custom water with TDP mod and xtreme gaming bios @2177mhz atm)

1080 G1 gaming here same thing higher score very good overclock with FE bios techpowerup has gigabyte FE bios in unverified uploads

Sry for double post.

Gabkicks can you confirm that the AB voltage offset slider is at 100% and that in the curve, the 1093mV freq offset exceeds the offset for the 1075mV point? If the curve goes flat above a certain point it seems that It won't bother boosting to those higher points.

I have a watercooled 1080 evga FE. My OC stays solid at 2126mhz; the card does not use more than stock voltage. However, powerlimit is constantly hit and I feel that is keeping my OC from going higher.

Is there a bios yet to change this? What about the physical mod; where can I find the best video/tutorial, and is it reversible?

Just got my maximum overclock with EVGA FE Bios. 2126mhz @ stock voltage and 120%TDP. With FTW BIOS I could get a maximum of 2113mhz @ 1.093V and 130%TDP. Also, After a few benchmarks, my TDP never hits 80%. While with the FTW bios it would get over 100% in the same test, same conditions.

That's crazy IMO. And like It was said above, I wonder if different BIOS don't make GPU-Z/AB read the information differently. It's not possible that EVGA, and all the other companies for that matter, would make a BIOS that makes their product WORSE. Not in a market where you gotta win from competition with higher clocks, lower temps, everything.

Really, that doesn't make ANY sense at all. Results are there, bat there's no logic to it.

Finished.

I run a Core X9 so I had to orient the tubing toward the front of the GPU. Need all the tubing length I can get to mount the Rad.

Anyone with a smaller case could orient the tubing toward the back of the GPU and still have the stock fan shroud on there too.

It will not make much if any difference though. Just aesthetics...

So... best Kraken G10 mod or what?

I'm going to throw it in turpentine to get rid of the paint and re paint the bracket once I take the card apart for maintenence.

We're still locked out of bios mods at this point. Some of the AIB cards allow for a higher TDP if you decide to flash them. However, as juniordnz is finding, the AIB bioses may be associated with a drop in performance relative to the FE bios.

If you want to do the shunt mod, it's very easy. Get a tube of Coolaboratory Liquid Metal Ultra (or pro) and use a q-tip to apply the liquid metal to the top of the resistors circled in the image below. Rub well towards the conductive ends of the resistor to ensure there is a good connection. You're basically just shorting out the resistor. The liquid metal can be removed later with turps without a trace - probably.
Reported TDP will drop significantly. Seems the reported number is not the same as what the card is using to determine when to hit Pwr limit though so you'll have to trial it to find the limits.
I disclaim myself entirely from liability for this information.

what is your max voltage ?


I'm thinking if is a worth to do thw TDP hard mod..

Thanks
1.093v rock steady.

Doooo ittttt

Some people (though trusted, not just joe schmoes) are saying that this mod locks clock speeds at low desktop idle, but I shorted the three resistors in question with 63/37 solder and a small piece of 18AWG solid wire, and don't have that problem, and have no attainable TDP limit biggrin.gif

That's a good point. I imagine this is a result of the card detecting that the voltage drop across the shunt resistors is approaching 0 and responds by locking clocks at 291mhz (from memory). I'd suggest that you're less likely to encounter this issue when using CLU as the resistance is higher compared to solder and wire. Further, CLU means the mod is more easily reversed.

Once I get my conductonaut in I plan on it. As all I'm using is the liquid metal I plan on just rubbing it over the on resistor under the 8 pin like in the video. Do you think this will work or do I need to do more?
