davidm71 Was finally able to get 1506/4000 stable at 1.2 v as far as I can tell. Tested it with various 3D benchmarks then customized my rom to 'Bake-in' 1506 as the default TDP Boost clock entry. Unfortunately for some reason while gaming it Boosted down to 1341!

I couldn't understand why it would Boost down or throttle as I raised my TDP values in MBT but it was using clock state #61 instead of #74 which I had set to 1506. So I had to shift down the values in the Boost table and shift up the voltage table to match.

Now it will auto Boost to 1506 and throttle down normally but I kind of cheated here it feels like.

If anyone knows why please comment. Attached my mod rom for anyone to take a look at it..

Thanks.


PS: Anyone know why if you unlock the extra two voltage column using KBT and giving it a voltage over 2112 why Windows fails to load and gets stuck at spinning circle?

RDDare What about editing of memory timing? Are there any values? As I know here Is only memory clock value.
I am working on pascal bios parsing via hex-editor, but first i should know what types of values response for memory (may be HUB or MSD) at clock states table.

davidm71 Guys,

Any of you have success modding your fan rpm profile? I’m having difficulty getting my fans on my 980 Ti Kpe to go faster unless I use Afterburner user defined settings. I’ve tried raising the numbers for rpm and per but doesn’t do much. Was able to raise rpm limit but need Afterburner to manually raise the max speed. Maybe you need to adjust the Minumum Temp Target?

Thanks

n1kobg I have second question.I reinstalled Windows10 & now nvflash dont work on my card .It says "BIOS cert.2 Vewrification error, update aborted"
Why cant re-flash the bios. What can I do? I pic&drop the rom on nvflash.exe.I used 3 versions so far including latest 5.370.0

n1kobg Guys, I just flashed my Palit GTX970 Jetstream sevral times and I get almost the same results as before. What might be the rason? Are Palit cards hard locked or what? In benchmarks i have higher scores but in BF4 my core was 1515mhz now is 1519mhz or maybe 15130 -something. WHAT IS THE REASON ????
The screen shows 1605mhz but it crashes. i give a link to the BIOS i edited:

navjack27 I guess lowering them makes sense for lowering your max overclock. Stock BIOS had my values all over the place but some of them actually way higher then my current values.

8051 I've been experimenting w/the L2C/SYS/XBAR values in my 980Ti. I was hoping by lowering them I could increase my core overclock. The strange thing is that lowering them resulted in less ability to overclock the core.

@ L2C/SYS/XBAR setting of 1394 MHz, I couldn't even get 1443MHz core clock stable, but at 1494 MHz L2C/SYS/XBAR I can overclock to a 1493 Mhz. core. But this doesn't make any sense does it?

navjack27 wow neat. i guess now we know a little more of what each of the things were in the bios editor.

if anyone was curious what my 980 ti looks like without wanting to open up a bios file here are some pictures for ya





EDIT: this is how you beat a 1070 ^_^

I mean I tested yesterday, set them all to 1392 and Heaven benchmark crapped out after 10 mins. Then I set it back to what it were before and run it without problems, at the same (main) clock speed. That's why I said "can of worms" touching these values smile.gif

Actually, in my research I found some of the factory overclocked VBIOS for the 980Ti's had higher XBAR/L2C/SYS values:

a. EVGA classified XBAR=L2C=SYS = 1455.5

b. Zotac AMP! Extreme XBAR=1431 L2C=1447 SYS=1479 (what I've got)

Two different ASUS models:

d. ASUS XBAR=1459.5 L2C=1492 SYS=1525

e. ASUS XBAR=1393 L2C=1424 SYS=1456

I believe the stock, reference 980Ti has the L2C/XBAR/SYS set to 1392 as you pointed out.

It turns out my problems had nothing to do w/o'clocking the L2C/SYS/XBAR on my 980Ti and everything to do w/an unstable o'clock on my CPU. I managed to crank the
XBAR/L2C/SYS to 1479 @ 1.87V Vcore and it seems like games run smoother w/those values than the stock ones.
