Nvidia C51 not supported by Riva Tuner

doc_nele

I wanted to try Riva Tuner on my home PC since it gave a new lease of life to my office computers (since we can at last play some stuff on our venerable GF2's andf 5200's :-). But RC 18 didn't recognize my (allright, onboard, but still Nvidia) 6150.

I added couple of lines to rivatuner.cfg file (I mainly "scrapped" the values related to C51 from driver inf files), and it recognized the processor speed as 475MHz (that's good), but also that I have 32Mb of 333MHz SDRAM (that's not good, since the memory is shared with DDR 400!). When I tried to open properties of the driver, it crashed (no wonder).

I didn't want to overclock it (much, at least-I don't desire a hole in the mainboard!), but some control would be desirable over some details, since I could use some performance in 2d for serious stuff, too...

Any help for this casual gamer? I can't afford Gf 6600 or something better!

Integrated / mobile GPUs are not supported and probably never will.

Oh, I see. So, it is for people who have fast cards and want to make it faster... I didn't know anybody's eye can track more than 24fps average...

Bye and so long.

you can use ngo modified drivers for such things

I have tried 83.10, and then it loses hardware overlay control in hardware decoding of MPEG-2. 83.40b works fast, but there is a hail of "artefacts". 83.20v2 works fine.

As I wrote, it looks like that not much is needed to "adapt" rivatuner to work with 6100 and 6150 (even I managed it partially!), but it does seem there are registry differences. Frequency tweaking, for example, doesn't work, since its entire memory is shared, unlike 6200TC.

AFAIK, 6150 is lot alike 6200 chip.

I mean, somebody can frown the nose to the onboard card, but if rivatuner supports Gf2/32, why not Gf6150? Because it is onboard? I don't even need freq tweaking, just various other goodies. "Because it is onboard" answer sounds like biggotry and doesn't cut for me.

You are probably refering to the "24 fps" used in cinemas?
The reason that is not unacceptable is, because of the film projector.
It is made to interrupt the light 3 times per frame, giving you 24 x 3 = 78 Hz.
You can see this effect also on a computer monitor:
If you set your monitor's refesh rate to 85 Hz, or 100 Hz, and use it like that for a while,
and then set it to 60 Hz, you should immediately see the flickering.
A normal human eye is able to see flicker at 75 Hz or below.

flickering depends on the resolution as well

resolutions of higher then 1280x1024 you will not notice 60hz

Allright, but I mainly run it at low res and higher sync-and it is mostly okay for casual gamer like me. I was "nauseated" by the first reply I got-I customized venerable Gf2 and Gf5200/64bit, so I felt "segregated" by the answer.

The problem is that without Rivatuner I cannot "fix" some things on 6150. Like "European Air War" that renders in 8-bit. For example, I cannot "revert" to older drivers (66.9-ish) sice 80.40 is the earliest C51 driver.

doc_nele, I don't know if you are aware of this, but the first reply you got
was made by the creator / developer / copyrightholder of RivaTuner.
I believe the reason RivaTuner supports all (non-integrated) Nvidia cards,
from Riva TNT (NV4) made in 1998, up to GeForce 7800 GTX (NV47)
is because Unwinder have an interest in those cards.
I do not know the reasons for why he uses his spare time to develop RivaTuner:
It may be because he wants the perfect tool for tweaking his own cards,
it may be because of some other reason,
but anyway, the fact that he does this, and then gives his work away for free,
is something that very, very many Riva/GeForce/Quadro users have enjoyed.

And if I remember correcty, he does not do it
because "he wants to help all the Nvidia users of the world"..
- although a lot of the posters here at Guru3D.com seems to believe this.

If he says he probably never will add support for integrated Nvidia graphics,
then my guess is that this is not because "they are too slow", but rather because
a) he has no particular interest in the integrated cards, and
b) it's easy to try out a new "non-integrated" card (just plug it in),
while changing the whole motherboard is not what you want to do very often

If you want to try out an old driver, which was made before your graphic card,
just add it's ID and strings into the "nv4_disp.inf" driver, see these lists:
http://forums.guru3d.com/showthread.php?t=171843
Using this technique I believe you can force installation of any driver version...

But, you should not install it with "setup.exe",
(because Windows may then use the "backup" "oem?.inf" in "C:\WINDOWS\inf\")
..instead you should:
--------------------------------------------------------------------
USE DEVICE MANAGER TO TELL WINDOWS YOU'LL UPDATE THE DRIVER

1. Start the Device Manager:
Start -> Settings -> Control Panel -> System
In "System Properties" window, select "Hardware" tab, then click "Device Manager" button
At "Display adapters", click the "+" to see the sub-level,
you should see an icon named "NVIDIA..." or whatever the name of your graphic card is.
Right-click the icon, and select "Update Driver..."

FORCE WINDOWS TO USE YOUR EDITED DRIVERS

2a. At the first page of the "Hardware Update Wizard", select
"Install from a list or specific location (Advanced)"
Click "Next >" button

2b. At the "Please choose your search and installation options" page, select
"Don't search. I will choose the driver to install."
Click "Next >" button

2c. Click "Have Disk" button,
browse your way to the folder with the extracted driver
and the edited "nv4_disp.inf" file.

clokkevi, I wasn't aware of that. If I had gotten fair&explanatory answer like yours, I wouldn't have minded at all. 'guess that he had a bad day or something

Thanks for info-I shall try this approach (modding the driver), but I am afraid that some basic differences will render it useless in RT (like coolbits "incompatibility"-not that I wish a smouldering hole in MB, but might be a sign of other problems). I will try to sqeeze the data from 6200SE/TC and cover my eyes

. I will try to mod 81.95, since my 6150 ran quite smoothly with it.

BTW, browsing through entries about driver modding, I've seen thirteen(!) more unnacounted "C51" graphics-related entries in the .inf file (from DEV_0243.1 to DEV_024F.1). Original drivers have only three entries (6100, 6150 and 6150LE) accounted for ('though I don't know what 6150LE stands for!). What the heck that means, a honest mistake or nForce5 reserved entries (all with onboard graphics???)?
