Because this cards power limit doesn't go above 104-105% even if i put the limiter to 114% which causes the gpu mhz go down. I was just wondering if another manufactures bios would change this thing rolleyes.gif

Sorry for my bad english, hope you understand!

I modded my galaxy bios the same way with the GB GTX 670 WF3 F4 CLOCK TABLE chart and mine works fine. the lines for the offsets are different with each bios but the hex code blocks are the same.

as you can see above thats what i was changing for just the volt mod. you have to save line 400 through in my case the ending for the offset was F5FF. ending offset will be different look at my image as example. then you wont brick your card lol. also pay close attention. the next line you will see VN@ you got to make sure that is there or your on the wrong line before. i think thats why i have had issues with the previous bios edits that i have done for others now that i think about it.

below is the table of offsets that you will need when modding your bios. im just not picking numbers out the air here guys lol.

you can follow the tutorial below it is in Italian but you will get the jest of what he is doing. also do not look for FFFF your ending will be different look at my image and what it looks like. you will have to go to the last block of that line of code. to get your number from 400 to ????.

im not for sure why its got me baffled for the moment.


Hi, I did volt mod on my MSI GTX670 PE OC and it works but there is one problem. Frequency is fluctuating during load on 3Dmark11 and as a result of this is lower score.
On original bios, frequency is constant all the time. Where in bios is a part of code that can be changed in order to maintain constant frequency?

I'm having the exact same issue. If anyone knows of a solution that would be great!

Anything above my current settings and crash!... i just want to be able to get at least 30-40 Mhz plus smile.gif, it would really help if i can. currently i have a 3d mark 11 score of P9462

Well. If someone can just help me mod this bios file. Evga reference 670.zip 56k .zip file

And set it as:
Core clock Clock = 1140mhz
Memory Clock= stock
Voltage= 1.2120v
Fan= 30%-100%
Power target =145%, (or whichever will be stable for reference. Sorry; i don't really know much about the power target on different vendors)

I will really appreciate it!.... if anyone at all can help.. or even tell me how i can do it myslef biggrin.gif

I modded immppa MSI PE OC BIOS (version 80.04.31.00.46) with power targets to 200W (100%) up to 225W and he is seeing this behaviour too. The first 2 tests show horrible down-clocking, even though power target is only reaching 91% and temps max. out at 64 degrees. Volts and CPU usage are exactly as they should be.

That said, I'm not sure why you guys are volt-modding seeing as you have it via afterburner in the first place already, it may not show it but apparently it's there (just read the afterburner thread).

Either way, you guys don't seem to be the only ones...

I flashed my MSI GTX670PE/OC with Galaxy bios GGC670_VMOD_FAN-20-100 just for curiosity. I'm surprised that it works, nice score +400 pts. graphics in 3Dmark11 ,stable +40Mhz, and no throttling down under heavy load, but fan functionality (Dust Removal technology) has lost mad.gif Flashing with modded MSI bios PE670_VMOD_BP-200-225_FAN-20-100 is pointless because of throttling down and lower score than original one. Maybe Power Target is the issue or something more rolleyes.gif
I'm looking for MSI GTX670PE/OC bios that has volt-mod and no throttling down under load thumb.gif

Nice thumb.gif , but be careful about temps on this bios. It's not designed for MSI TF IV cooling. Temps can touch 72C or even above that under heavy load.
I had to set fan manually to be under 62C.

EDIT
______________
I prepared my own bios, can be downloaded from here ->http://download.hellshare.pl/gtx670gc-rom/9204112/
It consist of MSI GTX670PE/OC original bios and modded Galaxy one. I took code lines addresses from 400 to F3FF from Galaxy bios and paste into the MSI one.
Advantages of this are:
- Dust Removal technology is working now
- card is recognized as MSI GTX670PE/OC so you can adjust mem and aux voltage in afterburner biggrin.gif

But temps still are to high under heavy load, so fan profile needs to be reworked.
The problem is that I have no idea how to do it mad.gif
