KGB - Kepler BIOS Editor/Unlocker

@crazynuts

things i discover i want to share with you the creator of this great tool

1) if i cap to 1320,5 i only get max boost 1293 and the funny thing is that only 1,23 LOAD max mostly 1,28, but if i cap to 1333 i get 1,245 LOAD

2) as i told you above i been trying all day to cap exact to 1293 and theres no go i tried all values

so far tool works great but maybe values maybe revised
the good thing of this is that i can play at 1293 / +700 all day at full load of this frecuencies at less volts before it runt 1,245 not 1,2 to 1,23 depends on the boost

cheers !

Try this one with 1320: https://www.dropbox.com/s/d6dimgnx8cxvlca/kgb_0.6.1.zip

Hm, 0.6.1 is giving me a maximum power target of 114 on my MSI PE.

Maybe I'm doing something wrong but my card STILL wont go over 100% power target even at stock.

BIOS start found 0400

BIOS end found fbff

Checksum: Good! a3

Model: GTX 660Ti Device ID: 1183

Found power offsets 7cec

Found fan offsets 7d50

Found voltage offsets 71cc

Found max boost offsets 6b65

Fan Speed Range: Min = 30 Max = 100

Power:
Power Target: 175000
Max Power Target: 200000 (114%)

Max Boost:
1306.5 Mhz

Voltage Table:
1150000
1150000
11500000

1150000

# Voltage = 1162500
# Voltage = 1150000

I'm trying to use kgb to flash my Lightnings to 1400 max boost. When I follow your instructions the file ends up as Max Boost: 1202.0 Mhz

Is this a value I can ignore or is this stuck at 1206 for lightnings? I'll admit it, I'm a bit of a noob.

why 1400 unless you increase volts it will fail to do 1400

try new kgb 6.01 works as a charm

KGB looks to be playing nice with your bios. I suspect your card may not be fully stable at 1306, the driver may be detecting errors.

Can you try: Max_Boost_Freq = 1293
Lets see how this works out.

Will be memory OC via BIOS there? Mine is factory overclocked to 6200.

you can always OC memory with MSI afterburner etc, point is if there will be unlocked volts on mem i guess that was your question right ?

You can go a fair way past stock on stock voltage, depends on the card too. 6200 is +50 and many cards can do up to +500. I have found the hex string for mem freq if Mr Nutz needs it.

Yeah man send me the offset for mem, and the bios file that the offsets you found match up to. I'll add it to KGB. Thanks

is mem volts anywhere like gpu volts Cryp ?

It's very unlikely.

Tested up to 1359 with no problems using previous version

Gigabyte GTX 680 SO, ventilator set 0-100% with KGB. Gigabyte OC Guru 2 installed. Now the card stops all the five ventilators below 25 C, 324 Mhz. Is this good? Ventilators start around 30 C, 2 of 5, and during game all the 5 operates "properly".

I think this huge copper cooler in 3 slots depth enough to keep the card cool in lowest performance.

But maybe somebody have other or better experiences?

And thanks forward for memory oc.

My plan after found stable/safe OC-s burn to bios, after I will uninstall OC software... any thoughts on that?

for ex my card has its own software XtremeTuner that shows till +40mv increase that you can give to mem, but MSI afterburner doesnt show it unless i flash a MSI bios to the card, so i guess in my BIOS maybe it is somewhere

btw heres mine GALAXY GTX680 SOC 2GB ORIGINAL not touched ROM
http://www.2shared.com/file/lSBeOULP/GK104.html

if you want to play with it there it is

cheers and thanks !

Thanks but I increased voltage via AB 2.2.3 after flashing the unlocked LN2 BIOS on both my Lightnings and my new OC is:

Core: 1424
Mem: 7204

Kombuster claims 1.21 V but I think is closer to 1.31. Mem is +100Mv.

Max temp is 47 Celsius with 99ish% load in Kombuster 2.5.

Will try to break 21k 3D11 (P).

Ok thanks i'll take a look.

thx to you :up:

Here you go man, hex string for mem freq in the msi lightning 680 bios:

http://i886.photobucket.com/albums/a...ps21172e16.png


Mem freq in the above example I have set to 48 4F (1956 Mhz) and appears in 2 places, offset 6E40 columns 6 & 7 and offsets 6E70 and 6E80 columns 0F and 00


DL the bios here: http://www.techpowerup.com/vgabios/1...48.120625.html

In an evga BIOS I looked at I found it at offset 6DA0 columns 7 & 8 and 6DE0 00 & 01. Stock freq is BC 4B so look for that if you look in stock mem freq BIOS. Hope that helps :) Any questions just let me know.

Thank you CrazyNutz for such a gift we all need it. :up: Excellent job :clap:

But I have some problems. I don't know why am I getting two diffrent bios readings after unlocking my original GTX680 bios (it should be 80.04.00.0F (P2002-0000), but it says 80.04.00.0F (INVALID). Maybe 'cause there is not enough space in BIOS Version NVIDIA Inspector. Is there anyone having the same problem or nobody noticed it yet.

Second problem is that I can't change Max Boost Freq in .CFG file. I stuck on 1202MHz and I have no idea why.
Everything else seems OK, no problems during unlocking and flashing and it works fine, except this one.

Here is my bios: https://www.rapidshare.com/#myrs_filemanager/file/0

If anyone is in the mood for mod, I'd be glad to see it.
Thanks in advance. :)

1. That's your checksum that says invalid in parentheses. The 80.04.00.0F is the bios version. In the KGB config file change preserve checksum to = 1

2. Max boost issue - did you take the hash (#) away from the boost option the re-save? If you leave it commented out it wont apply.

CryptiK, thx a lot! :up: You shot in the center of bull's eye. Man, it's working, hell yeah! :yepp:
