I need someone to test the modded 7800 bios

[Victorshen]

hi all, as per title
i include 2 version of modded 7800GTX bios here
they r both modded to 1.5v vGPU with 470/1300 as a default freq (stock vGPU=1.4v)

the only difference is that one is with thermal monitoring and one without (which i think is the cause of "coldbug")

i have two of my m8s testing the first one, but unfortunately, they dont have water cooling or some other xtreme equip to testify whether the second version DOES work without a coldbug.

i would appreciate those who can test it for me, xtreme ocer welcome :D

plz leave your feedback here so we can see wats going ;)

Cheers

Victor

[Onepagebook]

how to flash, instruction?
Thank you for your effort:)

[Jort]

tnx for you contribution victorshen, if they work many members will be VERY pleased.

i think nvidia should release it but again they will have many warrentyprobs with the bios.
so any 3th party is welcome here:)

[Victorshen]

use nvflash

save your original bios first

nvflash -b xxxx.rom

then flash this one

nvflash -5 -6 xxxx.rom

via dos ;)

one side effect is that you cant know the core temperature anymore

so i think thats one reason nv dont wanna release it

If this works: :toast: :clap: :woot:

(And this will mean I won't have to negotiate with BFG!)

[shadowing]

Did anyone even test it out yet? If it works, :woot:!

Question, is there a way to maybe redefine the temp tables? Rather than just deactive them, say that -100C is value0 in the table rather than 35C.

I guess the drivers would always say that things are 135 degrees hotter than they really were though, that'd be bad.

IDK, I just imagine there's a way to change it so that it completely works.

well, would you please explain more, I don't wanna screw these two cards.

1. what version of nvflash I need to get and where?
2.how to save original bios and what about the disk? need bootable disk?

Thanks

probably not, coz in the bios there is only one thermal throttling, that is above 115c, there is nothing indicating that it will also throttle under 35c, so my guess is that the cold bug is a restriction of driver.

so either you mod the driver or disable the monitoring

[Vapor]

Just kidding about OPB testing I guess...anyway, I'd also like to know a clearer, more defined way to do it, Victor.

i attached the 5.13 nvflash

my friend successfully flashed his xfx 7800GTX using both the nvflash utility and bios i gave him :D

if your system partition is Fat32, i would be easier
copy the bios and nvflash to a folder, say c:\nvflash

boot into dos

cd c:\nvflash

nvflash -b backup.rom (backup your original one at c:\nvflash)

nvflash -5 -6 xxxx.rom (flashing the new one)

p.s. i recommend use hdd to flash bios, if you DO need a floppy, make sure the disk is okay, personally, ive got very unpleasant experience flashing with floppy

[Vapor]

Alright, I think I got the gist of it. Thanks!

[Onepagebook]

final question,
I am stil confused
which one I need to flash if I wanna try on the water cooling?
7800A1OC-with Thermal monitoring.ROM

OR

7800A1OC-without Thermal monitoring.ROM


Thanks

the best way is to try both
first the one with monitoring
then the one without

so that we can know whether it works :D

hmmmm.....thats a bit weird, bios will only throttle the card when core temp>115c, but i think by just overclock to 530 , you wont get that temp :(

probably we shall w8 for the next driver.....

Nice OPB, and good to see that there is a bios that will disable the cold-bug. Maybe it would be worth looking into the bios & driver, and seeing if I can help towards finding the problem.

now im quite sure that the 35c bug is a driver issue than a bios issue :D

so we know which way to go :banana:

There's some crazy :banana::banana::banana::banana: going on...so what's the consensus now? No BIOS fix is needed but a new driver is? How did Shamino and OPP do it then?

[rilot]

Is the 1.5v mod working?
If so, what were your before and after clocks?

I will test this BIOS with my Leadtek tonight when I get home from work.

[pablo]

so basically until this is fixed i cant use my water with my card? i dont know if it will take it below that so ill have to see

[rilot]

1.5v mod doesn't seem to be working.

I can hit the exact same core clocks with my original BIOS as with this modded one. I would expect it to be slightly higher with a 0.1v increase. My 6800 Ultra gave me an extra 30MHz on the core with a 1.5v mod.

Can't confirm the cold bug issue as my computer room is so damn hot my WC rig never gets below 35 degrees.

ill confirm this as soon as i got the card :)

[railer]

Did anyone tried to up the lowpower3d in Rivva tuner? That helped with 6800. If the card drops performance after 530 on the core try to set lowpower3d to 550 and see if it helps

Onother way which could work is that you will need to make bios that start from your max bench speed. That has also worked on removing throtling on 6800's :fact: and increased the score by 300+ marks :fact: . So if you are having the problems after 530 core make bios that start @ 550 and flash the card with them. Then it would not have a lower treshold to trotle to . 550 would be min speed. Realy only people with phase or other extreeme cooling should try this. Then you just figure out what is your max bench settings and make bios that start from that speed.

Victor why dont you make same bios that start from 550 core and let OPB or other members try it . It should fix the performance drop issue. It's a chance it will work why not take it. You can always reflash back if there is a problem

[Vapor]

Very good points/ideas railer...

As for making the custom BIOS, the new NiBiTor does it, right? I might try it out on my own.

i think OPB just have watercooling, not phase change, so 550 may be a little higher, too risky IMO

and yes i agree with you that overclock via bios gives better score, especially in SLI mode, my bios overclocked 68U SLI get an extra 300 pts in mark05 comparing to the driver overclocked setup (other thing remain unchanged)

[Kinc]

Im going to run DI on my cards tonigt. I have a problem when going to high in 3dmark03/05. The cards drops to 2D performence with lower voltage and just 275MHz core. Could you see if you could raise the 2d-voltage to 1.5 also?

Many many thanks Victorshen! This bios really rocks!

[Victorshen]

oi the bios is coming
the pack include 4 bios

1. 2D=3D=500/1400 1.5v for all, both with and without monitoring

2. 2D=275 but still 1.5v 3D=500 1400 1.5v both with and without monitoring

also, b4 flashing
plz overclock to 500 1400 and take what score you get in mark05

then flash it, see is there any improvements :D

ah.. one last thing, make sure your card can do it b4 flashing especially the ram :D

[Desmondo]

I just checked your bios-es with the new 2.2 NiBiTor. I'm really aware of the problem because my 7800 GTX gonna arrive on Monday (I hope so :D ). I'll install my Innovatek block on it so I need some solution until then ;)

You can set the throttle frequency in NiBiTor 2.2.

I think setting the throttle speed to the same as the 3D speed in the bios is one way of solving the problem.

Thanks man, gonna try it right after work.

[Victorshen]

Thanks man, gonna try it right after work.
but:(
according to my m8 harry
seems the max vGPU we can get is 1.4v
higher than that we need hardware mod :(

[Victorshen]

here is two latest bios

as Harry told me that with 1.5v bios he got 4Mhz less in o/c
the new bios come with 1.4v

changes includes

no performance table--no 3D 2D freq anymore

no thermal monitoring (core and environment)

so you shouldnt see any temp anymore

other difference between the 2 bios is one running@ 470 1300 while the other 500 1400
i recommend the 1st one.

What 7800 did the bios come from. It looks to be an older version than the one on the XFX cards I have here. Also NVFlash errors saying that there is a hardware mismatch. (Ver 5.13). Am I missing something or are people just forcing the bios to overwrite. Right now I would like a bios at 450/1250 with no cold bug so that I can see what these card can do. Other than 4 FPS in 05.

[Benny Lodewijk]

thanks Victor, i'll try it on my Gigabyte 7800GTX

here is the result : http://service.futuremark.com/compare?3dm05=982004 = 9096.. you're rock victor :toast:

[Vapor]

Those aren't the real clocks, are they? 2900MHz and 540/1404 only gets 9100?? That seems more like a score from 500/1400.

[Benny Lodewijk]

yes you are right, the real clock is 500/1400. before i can't get good score with manual overclock 500/1400. With victor's BIOS, i can.

hopefully Nvidia will sort this out soon as id prefer to be able to keep a eye on the temps.

The 80.40 Forceware is worse points in the 3 Dmark2001 2000 like the Forceware 77.72

Both drivers are identical in the Aquamark of the performance

Is your X2 also watercooled? Those clocks seem lowish all the way around...my X2 and 7800GTX do pretty much those clocks on stock cooling (actually, my 7800 can do 520+/1430 on stock cooling, just gotta publish those on Tuesday).

Have you tried pushing any harder? I'd like to know what I can expect once my watercooling is finished.

[Usurper]

Well i havent pushed to hard at the moment, i dont know what the safest max core for the X2 4400 is, i have moved to 250fsb x10.5 ( 1.55 core) now giving me 2.63ghz, 2.71 wasnt happy at 1.55.
as for the 7800, i am not comfortable pushing too hard when i cannot see temps, id imagine they are ok but its the not knowing. TBH i think you are lucky on air with the clocks on your 7800, 520/1430.
I have seen a few reports of other people on water who cannot get past 495.

[zakelwe]

Looks like nvidia are going to release a new driver that removes the throttling this week according to evga rep.

[Usurper]

WOuld be nice to see my temps again.

on another note i can bench at 526/1380 (highest the "test changes" on the properties will will me do , anyway around this?) or should i try riva tuner?

i knocked it back to 515/1350 for 24/7 running, as i thought i saw artis on BF2.

Questions.

Is the bios you mention 1.5v? ( ignore me i see its 1.4 )

Kinc,thanks :) Ill try the above

Should i overclock via rivatuner? and if so anything i should change amend in settings?

[Usurper]

BTW when i use coolbits reg to get overclocking options, card doesnt pass 500/1400 in test :(
but passes 525/1380 .

[Usurper]

Just flashed to the "7800A10C-noPB-noHM-470-1300.rom"

I get no difference in overclocks, ( also forgot to change the clocks to normal b4 i flashed, just glad it went ok, pheewww)

also i still do not see my temps.

Use riva tuner for the tweaking and powerstrip 3.61 for overclocking. PowerStrip i shareware but what the heck, a bench disk only holds for so long ;)

Powerstrips allows for higher memclock and somewhat higher coreclock without jumping in to 2d-mode. Do not activate overclocking in rivatuner.

[happyhero]

i will be a guine pig when my card arrives.

[mr_gibs]

so basically until this is fixed i cant use my water with my card? i dont know if it will take it below that so ill have to see

all i did for water was loosened the block untill i had the correct thermal contact to get exactly 38c (that's what it starts working at for me) so now i'll just sit back and wait for this new driver or bios or whatever is going to happen :)

[pablo]

i dont understand is it a bios problem or a driver problem?

[zemzelett]

Bios worked great for me on both my cards, works fine in SLI mode as well, seeing the temps really doesnt bother me, the whole point of flashing the cards was because they was to cold, and besides, i can see the water temps.

Thank You very much for helping us out with this "cold bug"

[Victorshen]

cheers all,

as for many of you claimed 530 as the wall, im thinking that it may be related to the +40 Geometry clock, which is running @ 570 at that time, probably tweak that clock down to the same clock as shader and rop will solve the problem.....

[Victorshen]

hi all,

here is the latest modded bios

now geometry clock = shader clock= rop clock=470

other things is the same 470 1300 1.4v no coldbug :D

guys with rivatuner 15.7 can testify it, others may just try this bios to see if it gives more o/c ability, use at your own risk tho :D


[update] one of my m8 tested it, seems got some problems

i deleted the bios

What went wrong??? any idea? wich is the latest stable that u leaked?
Maybe i will give it a shot ;)

[Kinc]

You got PM Victor.

I'll sumbit it here for everyone to coment on it:
My thougt on the problem with the different clock domains is that it can be solved by forcing the card to operate in 2D mode. I've tried this with RT and it works great. It's just that the vcore drops to 1.2V so 470MHz is the limit for me with default cooling.

Do you think that you can make a BIOS only working in 2D mode @ 1.4V. with standard clocks of 450/1300? In 2D all the domains will work of the same multipel and totally syncronos without the +40 thingy.

[Victorshen]

What went wrong??? any idea? wich is the latest stable that u leaked?
Maybe i will give it a shot ;)

he flashed it, but cant boot into windows when drivers is loaded, uninstall the driver under safe mode, he can get into the os, but once the driver is installed, the same thing happens

since under 2d mode all the domain clock is the same. maybe deleting the performance table may help, ill have another try :D

Do you think that you can make a BIOS only working in 2D mode @ 1.4V. with standard clocks of 450/1300? In 2D all the domains will work of the same multipel and totally syncronos without the +40 thingy.

i think we can diable the performace table
use only one freq for 2d and 3d :)

[giorgioprimo]

Update? :slobber:

[Usurper]

wheres this DET driver they been promising to remove the bug and allegedly be better for clocking? ggrrr :(

[drunkenmaster]

hmm, so far i could back up the original bios to the floppy in dos, butthe command to flash, nvflash -5 -6 bios.rom doesn't work, keeps saying I/O error can't open file, am i doing something stupid. i put in the actual bios name, which is the nopb,nohm, 470/1300 version, onto a gigabyte 7800gtx. at the moment i can't run anything as its too cool and just throttles. :( any help or pointers welcomed.

here is the correct typing needed.
nvflash -4 -5 -6 bios.rom


here is my results.
504(546)/1370 = 9092 3Dmark05 default bios on air.
530(530)/1377 = 9053 3Dmark05 modded bios on water.
it seems that the modded bios geo clock stays at the overclock speed when in 3D instead of boosting the extra 35-40mhz. so i am stuck at a wall at the moment.

[Rpg_pro]

Guys that are wondering why it shows higherclocks in the 3dmark scores, Look at this that i made.


Now onto the bios topic, Will modding my bios void my warrenty? I was shipped a BFG 7800gtx with 460/1200 clocks, when 460/1300 was advertised on the site, this is fixed with a bios update, yet i can't find one on the BFG website.

the extra 40Mhz is the Geometry clock, its running @ 40+ speed that of shader clock and ROP clock....

flashing bios, IMO never void warranty, you can always flashback if you want....

the new Nibitor 2.3 support Geoclock mod already, works fine :clap:

What if the flash fails? is the card screwed? or can you reflash?

[troid]

Yeah you can blindflash it if you don't have a pci card.

[Wise Guy]

#94 well I con´t the maschine vould´nt boot so I had to find a PCI card ....

[diehrd]

I read through this a bit ...BUT I never noticed any one mention the fact a 7800GTX in a 3d performance mode automaticly PUMPS up the core 40 Mhz from what ever setting you select..So at say stock of 430 when you bench or game the card it jumps to 470..And setting clock at 500 means you have to add 40Mhz to that when stressing it in 3d performance mode...

If this has been covered please ignor it..However if not I would suggest your difficulity is due to this feature . . .

[BigStan]

Is anyone still flashing these BIOS files? If so, How's it going? If not, what BIOS' are you flashing now?

[PuNiShEr]

I think i will try one of your bios Victor, on my ASUS 7800GTX... Now, with the stock bios and stock cooling i'm achieving 520 / 1350 for day use...

Keep on the good work m8 :toast:

[Tamille]

I stopped using the modded bios files as soon as i vmodded my card. i now use the original bios. vmod is the only way to increase your voltage.

The main reason for flashing to this bios is to disable temp. monitoringr. I used the 500/1400 one in post 46. This card hits easily over 1450 w/o mod so all is good w/ that one. :) BTW I am vmodded also. ;)

[VoRtAn_MaDgE]

Just flashed my 7800gtx from xfx with the bios that brings 470/1350 clock default...

Didn't loose monitoring temperature :)

Cooling is still stock, no vmod's (YET) :D will try the 500/1400 later with this cooling perhaps, will think about it ;)

[Kinc]

Is that without any coldbug? Where did you get it?

and that didnt matter anymoa because with the 77.76 it should be fixed theres only 1 problem these drivers arent FM approved.

[harleybro]

Agreed once they are I may switch to them and bk to the original bios but for now would rather run approved drivers. :)

[Kinc]

I have tried 77.76 when @ -70C and it did not work. It works fine for -50 though.

[Crazy Chuckster]

Just FYI the eVGA 7800 GTX KO bios is available here http://www.nvnews.net/vbulletin/showpost.php?p=669790&postcount=22

490/1300 stock speeds.

[VoRtAn_MaDgE]

Does anyone related gains just switching the factory thermal paste ? :rolleyes:

[IYP]

yeah....thats the first thing im doing when my cards come in...AS5 up the cards

[Usurper]

anyone tried the 77.77 officials?
they cure the cold bug or boost performance?

[GoriLLakoS]

Anyone so far that have a bios to play with the cards under -190C????I want to play with ln2 but noone want to give me the bios.....pls help

[harleybro]

There is none. It's the core and not the bios that limits the temperatures.
-80c is the best I have heard of these cards doing. So play with LN2 and just do small pours. ;)

[cinOxen]

My first post on XS :)

This bios worked great for me. I have a 7800GTX with a 172W pelt and the 77.77 driver wasn't addressing the "cold bug". I would get a BSOD every time I ran a 3D app. The card works fine now and the on-board sensor reads -12C. Unfortunately it hasn't overclocked well peaking at 530mhz for the core. Guess I'll have to volt-mod it to get it higher.

[Ubermann]

I was making some bios from the EVGA KO bios and first try i got ambient temp reading.
I havent seen that one before or maybe i missed something but it was working.
Ended up with one that has only 1 performance level and no +40mhz and 1.4volt all time.
Gained 300+ points in 05 compared to non modded bios.

[Weee]

:clap: VictorShen, you are my hero. I almost had an aneurism when I set up my pelt cooling setup on my BFG7800GTXOC, powered it on, set up windows, went to run a 3d bench, and bam, computer froze. I found this thread, and I was a little scared to do the flash, but I looked through and saw a few good experiences so I went for it. I had the 78.02 Drivers, cold bug was not resolved for me

Here's my experience:

GPU and ambient temperatures are displayed, gpu idle = -5C

clocked to 570/1360 scored 9263 3dm05

I used the 1.4V 470/1300 version of the the BIOS, from post #46 Pg2 of this thread!

:clap: :woot: :clap:

time to start tweaking, then flash card #2 and go to sli ;)

edit:
9457 583/1360

Vapor, I think its the ram clocks, and possibly some throttling, but its a lot better than the 0 3dmarks I was getting before.

I need to put a nice big fan there, right now just ramsinks kind of surrounded by the neoprene for the insulation,and no direct airflow, they need to breathe!

[Vapor]

That is a very low score for your clocks...I'd expect nearly 10k with those clocks. Sounds like a throttle issue of sorts.

try dropping from 583/1360 to 581/1360 and you will get a better score.

(23 x 27) - 40 = 581

[eclypse]

Well, i've come to find out that using either a modded bios made from the thread auther here with no temps nor throttle mode and my original bios edited by taking out the throttle mode made no difference in overclock and final 3dmark score.

So its not like the only thing you can do with water cooling your card is loose the temp monitoring to get these cards to run full speed.

Onto the overclocking..

So far i'm limited to my mem cooling.. Since these OCZ BGA copper heatsinks have been used before twice and now the double sided tape is trashed and not making perfect contact by any means i can only get less then 1400Mhz on them stable.. ruffly around 1386Mhz. I have 2 sets of 8 frozencpu monster BGA copper heatsinks on the way

The GPU i have benched up to 530Mhz.. now i cant remember if thats 530+40 or just 530.

Not bad i guess with no mods done.. YET!

Strange part is that i can get the mem to bench at 1400Mhz or more only if i down clock the GPU to say under 500.. Like 480-490.. So i dont know if thats just like a power issue or what.

My top scores right now for 3dmark off the top of my head:

3dmark 01 = 35,800+
3dmark 03 = 32,000+
3dmark 05 = 13,000+

Do these scores seem about right for my rig? I'm using the 78.03 drivers i believe.

this is 1.4v or 1.5v for GPU ? anh what's your cooling ? stock Fan ?

Can you give me that bios ?

[Sparxxxy]

any moded bios for the 7800GT ??

[Veil^^]

My XFX Does 490/1470@orig bios/stock cooling=D=D=D Just need to get a better gpu cooler and it will do atleast 520+

[aldamon]

any moded bios for the 7800GT ??

Yeah, any 1.5V 7800GT BIOSs out there?

[Mavke]

Yeah, any 1.5V 7800GT BIOSs out there?
Yes there are some but you can just make a backup of your own Original GeForce 7800 GT BIOS and then use NiBiTor v2.6 and do the needed to set it at 1.5V. Or just contact me and I do it for you. :)

[OverClocker_gr]

Can anyone to mod a bios for my 7800gt to remove coldbug?

[OverClocker_gr]

??????
Nobody?
So The coldbug is @ bios or @drivers?
