Evga gtx1660ti xc crossflashing

To get rid of power throttling, I've been looking for different vbios. So far I found following: MSI GTX 1660 Ti VBIOS
The cards have same vrm config but the vrm controller is tiny bit different, NCP81610 vs NCP81276.
Other differences are output ports layout and fans.
Only problems what can be foreseen are that port(s) are not working or the fan is not working correctly.

How important same vrm controller and phase config is? Seems like people take the change with totally different vbioses not paying much attention in them.

That bios in the link has 140w power limit that would be ideal. If the ports wouldn't work, could I try some 160w PL vbios with same port config (but maybe different vrm conf)?

You are better using Curve editor from MSI afterburner (or similar software) , your card has a low chance to work correctly after crossflashing.
I got my power limited 2060 super to work at higher clocks with lower voltage / Watts / Heat using curve editor.
Even if you increase the power limit by crossflashing you may have less performance due to more heat and your card will boost lower than stock.

What you can try if you really want to flash (but you may brick your card so do a vbios backup before) is to use one of this vbios (all are EVGA with same ports but dual fan so your fan might not work correctly after flashing):

Your card has 130W power limit. (after reflashing with an higher power limited vbios you can decrease the power limit from software to your preference)

160W to 216W power limit - ( Edit: i think this one is using the same board but with a better cooler , so i would start with this one, i am guessing that it will work)

Your board vs other board ( they look pretty much the same with one power stage missing on your model)

vs

Let us know if it worked or not.

So it doesn't matter that they got different power phase design, 4+2 vs 6+1?

Now I'm sitting at approx. 2GHz @ 900mV 55c stable gaming but hitting power limit thats unnecessarily throttling.

You should try and see , i cant be sure but i think it will work. Be sure you have another video card or your CPU has iGPU just in case the cards bricks (save your existing bios from GPU-Z) so you can flash it back.
I think 2GHz its the max you can get with your current GPU cooler.

Ok. Got igpu & backup.
I had asus tuf gaming 1660 dual fan oc that had inferior heatsink design and prolly was used for mining (had crusty thermal paste even though this is 3yrs old card) that went almost 70c in gaming (running at over 2.1GHz tho) so compared to that this 1 fan cooling is brilliant and totally amazed me in its performance. Much better than that asus dual fan system.
Thermal limit is not a problem and vrms can handle 140w, just need to get that power limit up there. It starts throttling right when the action starts and gives those nice stutters right in the moment when every ms counts.

I linked you 3 vbios files that you can try, start with the first and hope for the best. Good luck

Edit: When i cross flashed my 2600 super i couldnt find any vbios from a card with same PCB and same outputs , most of them bricked my card but i still found some that worked , the only problem with the working vbios was that the fans were not working correctly (they didnt spin too the max) so i reverted back and used the MSI afterburner curve editor and everything its fine. I think that this vbios files that i linked you are the closest you can get for your card.
