KGB - Kepler BIOS Editor/Unlocker

[nuno_p]

explain ?

With the previous version of KGB i could only boost to 1180(more or less) without crashing in heaven benchmark now i can do it at 1225 max boost clock.

great man !

Sure you were using the same voltage? That's just weird if not.

[STEvil]

1359 on both my cards @ 1.21..... as long as I keep them cool that is

Can only game up to about 1306, asus heatsinks are junk and hit 86c+ easily

Yup, same voltage.

Nice clocks man, bench or game at that if temps are controlled? What is 'cool' though? Under 40-50*C or you talking sub zero night air etc? Canada can't be warm right now lol

Yup, same voltage.

Maybe it was flicking to a higher boost level and causing instability, now it's fixed and unable to exceed the max verified stable?

Could be that, yes.

The boost cap feature is very nice indeed.

Good job.

i unlocked my BIOS the GALAXY 680 SOC

with this settings

# EXPERIMENTAL: This Setting makes the checksum calculate to
# the same value it originally was by manipulating an unused
# section of the bois. This may be needed for the new style
# UEFI vbios. Set this to 1 if you want to preserve the orig
# checksum. Set to 0 for the previous behavior of re-calculating
# the checksum. NOTE: if you're not having driver detection
# problems leave this at 0.
#
Preserve_Original_Checksum = 0


# Fan settings
Fan_Min = 40
Fan_Max = 100


# Board power settings
Max_Power_Target = 200


# Max Boost Frequency. Uncomment this if you want to change the
# maximum frequency your card will boost to.
Max_Boost_Freq = 1320 ----------------------------------> with this setting it boosts to 1306
Max_Boost_Freq = 1333 ----------------------------------> with this setting it boosts to 1333

# WARNNING:
# The following are valid voltages. I suggest you
# use these values rather than coming up with your
# own. 1212500 is the max and it is normally hard limited.
# If you go over the max and your board is hard limited
# you may actually get a much lower voltage than you
# expect.
#
Voltage = 1212500
# Voltage = 1200000
# Voltage = 1187500
# Voltage = 1175000
# Voltage = 1162500
# Voltage = 1150000

do i need to put 1321 for ex ? as i tried before with other bios and i was exact at 1320, also when i check KBG GALAXY.ROM says 1320,5 but does not boost to that only 1306

*edit i tried
1327 and boosts 1333 LOADS 1,244 max
1326 and boosts 1306 and shows on KBG info 1319,5 LOADS 1,238 MAX

weird huh ?

[CrazyNutz]

I think is correct because the settings for the boost clocks seem to be in ~27mhz increments. When you input a value for this in KGB it will round to the nearest valid frequency.

[CryptiK]

nvm ............

I re checked all again and clocks go like this

1288
1293
1306
1319 ---> this i cannot cap whatever i do
1332
...


at least on my card, it doesnt matter im just reporting back
cheers and thanks
Sergio

pd. for those searching the best tool to test stability on cards go FAR CRY 3 at ULTRA settings MSSA 4 - 1920x1080 and it will crap out in some minutes---

[CryptiK]

I thought it was in 13 MHz increments? As sergio put above (his first number 1288 is a typo) it should be: 1202/1215/1228/1241/1254/1267/1280/1293/1306 and I would have though from there 1319/1332/1345/1358 etc

yes its 13 increments Cryp i can confirm that

[CrazyNutz]

Ok yes its 13 or 13.5, In the bios its * 2 thats why i was thinking 27

@andressergio: That is very strange that you can not get 1319. Perhaps I'll code the value as 1319 instead of 1319.5 in KGB. Maybe the card rounds up and .5 is pushing it over to the next
valid frequency.

[anuraj1]

I ran KGB .5 some time ago and it seems to be working well. Am I supposed to run it again with KGB 0.6?

thx mate

If it ain't broke don't fix it

If I keep the GPU's at about 65c or less then they will game/bench at that easily. I can only manage that with a single GPU at a time and several fans pointed at it. In SLI things get HOT..

[STEvil]

.6 did something weird. My cards were stuck at 700mhz for most games, then crashed right as BF3 loaded, couldnt tell if clock speeds ever made it over 700mhz..

[noby74]

Does anyome have a new bios file for the MSI 660 ti cards with uefi gop enabled?

I am looking for this bios :-)

[CrazyNutz]

Post your original bios so i can check it out. Also post your kgb.cfg

Thanks

[noby74]

Ok I got the Uefi Bios for the MSI Power Edition 660 ti Card now and Flashed it on my Gigabyte Windforce 600 ti.

Works fine.

I am using the Kepler Bios Editor V1.1 now.

Interesting fact ist that both Bios use a "power level" of 39 as max value. 39 on the gigabyte is 1241,50 Mhz, while on the MSI it is 1228,50 Mhz. This doesn't go any higher even if I increase the Power Target more. 39 is the absolute max for both Cards. I wonder why the power levels 40-45 up to the max Boost Speed 1320/1306 are never used. Still you can edit each power level to you comfort, but why are the max levels never used? I will probably go ahead and edit Level 39 to 45 to my max stable Speed at 1,150 Volts, which seems to be about 1260 Mhz, and I guess I am fine forever...

Hi CrazyNuts,

I notice that commenting out the max power target and fan speeds has no effect, it will still modify the bios to 150 and fan speeds 30/100. I'm only trying to modify the voltage from default 1150000 to 1162500. Using kgb .6.

[CryptiK]

Same with commenting out the voltages. Changes to 1.1875 anyway.
