tdp is low, why?

was this after a bios flash? If so, tpd should be lower...84% of 350 (if that is waht you modded the bios to be @ 100% tdp) is 294 watts...I don't know which card you have, but I can bet it isn't rated at 294 watt tdp "out of the box", so Yeah, might be normal.
 
 
Also, big thanks to all that participated in this thread, I learned a lot and it helped me feel confident enough to mod and flash my bios.

This is flash bios from overclock . net 1.25v 425w
I overclock my processor 4.545mhz and have same score 2655
what problem with computer?
any help,any advices)

Make sure your graphics card is installed into pci-e slot #1 the closest slot to the cpu. Make sure you have no other expansion cards installed into the system other than your graphics card. Make sure your gpu is running at pci-e 3.0 x16 @ x16 3.0 when being loaded, this can been seen under gpu-z. Try performing a clean boot of windows to see if it helps increase your score. Try some different drivers other than 358.50.

This giude should help you figure out how to disable the boost on your card. If you can't figure it out I'll help.

Sorry for me it dark Forest

 i want  put voltade from slider AB (my videocad Part Number: 06G-P4-4992-KR
Part Desc: EVGA GeForce GTX 980 Ti Superclocked)
in default i want 1100mhz-1.193v or lower 1.187
and then from AB use Core Voltage put 1.255 or 1.287v-on future and push 1600mhz -you can do it in AB voltage slider will be work?
Thank you very much for you help and advices, please help

Here is the 980Ti-SC-MaxAir bios with boost disabled, 1100 default, 1.25v for any frequency at load... http://www.mediafire.com/...tw/980Ti-SC-MaxAir.rom

Sajin thanks for all the help in forums, sorry that I have not been here to help, been soo busy with college .... I will be checking on this though to helping any questions you guys got also.

No problem. 

on my old titan with boost off 
everything simple for understanding
 

Check back in a bit I'm going to make you a better one. 

614318 here is a vbios made specifically for your card only...
 
980Ti-BenchX:
 
- 1.250v at load
- 425W at 121% - 350W at 100%
- Boost disabled.
- Boost locked to 1608MHz. 
 
All you should have to do is adjust power limit to 121% & set memory clock +493. Do not adjust the core clock it's already set to 1608MHz at +0. 
 
This vbios should also read correctly in GPU-Z. 

You say 1.25 but in load 1.274v
2622score- do everything like you say
maybe trouble not in videocard 
it read correctly in GPU-Z 

Thank you for your help)

Just out of curiosity why did you guys not use the 1420 MHz bios Sajin made a few posts ago :o? And just worked your way up from there? 1420 is a sweet spot to start overclocking your card upwards if you have a good card. Sadly I got bad luck of draw and have to be stuck at 1420  

I never deleted the 1420X file. It's still working and can be downloaded right here... http://www.mediafire.com/download/08kgg9vh6hjs0t6/1420X.rom
 
 

So I flashed it, I opened this morning Star Wars. The menu was coloured in indigo then it crashed with this error:

 
 
Is it possible to raise the voltage or must I scale down the gpu clock?

 
 
 

Ok I tried with these datas and it seems to be stable (1483 MHz)
 

 
Thank you Sajin! 

Your power table for the 2 PSU rails are set to 375W each? I'm pretty sure they can only handle ~200W each. I know it will never actually draw 375, but still, why set them above what they can safely draw? IF you set them to 200, and you correctly left the PCI-E rail to 75 (which you have), that still gives you access to 475W, and since you have the TDP set to 450 and the power target at 425, that is still perfectly within limits. Also, have you noticed what the second table does? I have been unable to find any information on it, other than it controls some "Internal Rail" that no one seems to understand, lol.
 
I'm still learning about bios modding, but I am an engineer by trade, so I have a pretty good grasp of electrical theory and industrial applications, but I don't really do much electronic stuff, so I appreciate there are gaps in my knowledge.
