Hi, someone can help me with my MSI GTO?
I've mounted the GTO BIOS v3 by MVTech and modded with NiBiTor with value of:
3D 650/800 Delta 0
Th 550/600 Delta 0
2D 300/400 Delta 0
So 2D all ok and stay to 300/400
Using RivaTuner monitoring i see during games my card goes up to 650/800 and after few minutes turns down to 550/600.
WHY?
Pencil with 1.9v mem and stock cooler, temp 55°C
And someone can explain me what is the geometric delta clock?:p:
THX
Delta is the value above the core clock at which the ROPs operate. For instance, if your core works at 650MHz and the Delta is 50MHz, the ROPs will work at 700MHz. Won't make much difference in performance, but will limit OC sometimes.
Try this BIOS I attached, but please don't ask why it doesn't identify the card as GTX eventhough in BIOS it's set to do so, I have no idea. I tried all BIOSes and all of them do that.
Ok, thanks but this is a GTX or a GTO bios?
I want to mantain GTO because i don't have SLI GTX dreams =))))
Open it in Nibitor and you'll see. It's orignally a GTO BIOS modified with GTX ID and GTX clocks.

My GTO is identified in windows as a GTX. ;)Quote:

I must be doing something wrong :(
By the way which method do you use to pencil one resistor so small like this ??

Method A (trought the PCB) or B (trought the resistor himself) ?
How the heck ?Quote:

Folks ... my GTO is flashed @ GTX (650/800 w/ no vmod's ).
But something really weird happeans ...
In a friends computer this vga is 100% artifact free at 2D/3D.
In my computer at 3D all is ok but at 2D I get artifacts ! Small pink/purple dots in windows ! WTF ! :confused: :confused: :confused:
Any ideas ???? Both systems are equal ( p5b dlx + be quiet dark power pro 600W ... )
Did the reading on the vmem and it's at 1,815v
Tried in my computer the 91.xx and 93.xx forceware drivers and the 0614 and 0804 P5B Dlx BIOS.
Always get artifact's at 2D beyond 730MHz on the mem !! :(
Shouldn't it also occour at 3D if the mem was not handling well the 800MHz ?
Mine too :)Quote:

Dont think soo .... 600W (same psu as my friend) and the case is a well coolled stacker ;)
And why doesn't it also give me artifacts in 3D ??
I've noticed with NiBiTor that in the bios file that I flashed the 2D has 800MHz specified for the mem (as in 3D) !! Shouldn't it be less ?
OK, but what version of nvflash did you use ? Because I think the one I use doesn't overwrite the GPU ID when flashing.Quote:

Before re-flashing to the GTO BIOS, I measured the left resistor and the mem voltage and got this :
resistor: 1.004 Kohms
vmem: 1,815v
Hummm .... it seemed that the cause of my problem (650/800 gived artifacts at 2D) was the lower mem voltage.
Then I decided to give it a try to the pencil mod.
After some 10 tries and retries (man it's so dificult to pencil one so small resistor !!) I've reached 0.777 Kohms and that gave me 2,03v in mem.
Now the "Autodetect" in Forceware drivers gives something like 656/860 !! when before at 1,815v it didn't even work !
GREAT !
Now when manual OCing the mem with the GPU @650MHz , and testing by the drivers, it passes till 885MHz !! :D
When OCing the GPU with mem @ 800MHz , and testing by the drivers, it passes till 720MHz !!
I know from the XFX 7900GT that the max GPU OC depends on the mem frequency and vice versa !
So the question is : should I OC the GPU to the most it could handle and them OC the mem or should I OC the mem to it's limits and then OC the GPU ? :D Must bench mark to now that I know ;)
Others questions :
- should I try to get more voltage to get a more higher GPU/mem relation or 2.03v is good for a 24h/day use with the stock cooler ?
- if I return to the GTO BIOS I will get a better OC ?
- the right resistor should't be penciled to get the GTX omhs too ?
1. Wouldn't advise it, 2V is high enough for this RAM, there are plenty of cases where 2.1V kills the RAM.Quote:

3. Definitely NO, that handles the REFIN value, should be left as it is.
Isn't thhis kind of mem 2,15v rated ?:confused:Quote:

Alexandrus, just flashed your bios and love it ! :toast:
look:

:banana:
705/950 by the drivers ! Cant wait to go to Powerstrip :D
Glad you like it m8, right now I am trying to make it identify the card as GTX and then I'm done ;)
I was using the coolaler GTX bios and windows identified my vga as a real GTX ! weird.
As an information to you I used the same nvFlash version and parameters to flash coolaler's GTX bios and your's ! Version 5.36.
Heres a q:
This is for vgpu,i only got 20K,50K and 100K var. resistors,can i use them? If so witch one and what should it been reading if i want +0,1v up on my gpu?
Thanks
Norz
Original value is only 25ohm. So it is hard to do vmod with 20Kohm vr. I have tryed it and I can tell you it was hard. First nothing happens and then suddenly your voltage raise a lot.
I suggest that you buy 200-500ohm vr and do Vgpu mod with it.
Shouldn't you use a VR which is about 20 times bigger then the original value?
So 500ohms VR should be used and not 200-500k, that would only mean that you would have bigger steps. Since you get too big steps with 20k you would need a smaller VR to get smaller steps.
Thanks. That's what I ment. (200-500ohms)
