NVidia Help Page + OC advice / Steps to take if your 6800 isn't working

1) yes (well infact it tells the PC that the card is infact an ultra)
2) maybe if temps allow/the memory can hack it
3)before you flash back up the bios with

Code: 
nvflash.exe -b backup.rom

then just flash back with

Code: 
nvflash.exe -5 -6 backup.rom

REMEMBER if a flash goes badly wrong you vill need a PCI graphics card to recover your system

How could it go wrong, aside from a well placed power cut?

Not wanting to put water on the fire but a poor chap flashed his motherboard to a new bios and now it doesn't work, see help wanted to hotflash MSI Neo bios in the MM.

I'm hoping I can do it for him, just wanted to point out there is always risk albeit small that it can and does go wrong sometimes :(

The guy with the Neo 2 is very experienced with flashing but he copped for a bad download it would seem :(

I just think everyone should know the risk they are taking before they do a flash ;)
 
Another question... how do I put the files onto the floppy? After I've formatted it as a MSDOS startup disk, I can't put any files on it, it just says it isn't formatted :confused:
 
Tried it on 2 different disks, both of which were workign before, and it didn't work :confused: Just sat there trying to read the floppy and eventually told me it wasn't formatted, crashed the first time and had to reboot.

Hmmm knowing my luck the whole thing will probably go **** up, so I'll have to get hold of a PCI graphics card first :o

If your not confident do more reading and do it later, that way you will gain more knowledge and be able to do it feeling more positive, when I did my first motherboard BIOS flash I had heard loads of bad stories, so I read as much as I could find then printed it off so I could repair it if I couldn't get back on line, now I have done probably 150 flashes I feel much easier about it, use quality new floppy discs and keep them in the box clean and away from heat, you will be much more geared up and no doubt this time next year you will be writing this helping others ;)

OK I'll read up on it first :)
I do seem to have amazingly bad luck with computers though :(

Best I think and as you know they are great on here there are people on here who have forgot more than I know and yet they can be bothered to help us, this is a really great forum makes be feel lucky that I found it. Good luck with your reading and don't be frightened to ask, people on here are glad to help and we all hate doomsday episodes.

If you are getting distortion or artifacts/sparklies

Artifacts look like odd triangles or mishapen/distorted textures
Sparklies are... well sparkly, youll know it when you see it

If you get sparklies (little sparkly dots or squares) Lower your core!

If you get artifacts (dark/distorted triangles) Lower your memory!

These issues are nearly always due to damaged hardware or too much overclocking, it amazes me that people still come in and ask about these because if you dont know what they are you should not be fiddling with clockspeeds!!

Ok what to do,

1) If they are being displayed during POST/Startup, then get the reciept out cos youre cards a goner (it may be possible to correct with a bios flash but it is not worth it because you will lose your warranty, the same goes for poorly seated heatsinks)

2) STOP OVERCLOCKING!!!! (for now ;) )

3) check your temps, most drivers for newer cards include a temperature monitor available in the bios options. on 6800 cards around 50idle on stock cooling is ok. If its fine goto 6 if not goto step 4

4) Check your GFX card fan is working, I stick my finger in it but i dont advocate this, look dont touch :) , if all is spinning then remove the GFX card and tighten the screws CAREFULLY that attach the heatsinks to the board (PCB). If this fixes it goto 6 if not goto 5

5)You have two choices, send it back, or take your life (and wallet) in your hands and remove the heatsink and clean off all thermal compound/pads (gently, i use ethanol wipes but im not sure what is the safest, you can buy some citrus based cleaner here). Reapply the heatsink, or go all out and buy an Arctic cooler unit, but ensure you purchase the correct model for your card!!! these are available right here at OCUK
for around £15
You may also want to pick up some Artctic silver 5 (known on here as AS5 surprisingly) which you can buy here
Clean the chip, apply compound, replace/install heatsink.

6)It is advisable that you have sufficient airflow in your case, make sure you have at LEAST 1 case fan and if possible 2 or more to stop these issues from arising in marathon sessions

7)start overclocking again because you know you want too :)

I am sometimes getting these sparklies on the POST / BIOS logo image that appears on power on.
I haven't OC'ed anything yet, was runnign the latest Nvidia drivers downloaded from their site, all standard cooling on a NF4 SLi-DR motherboard.

I had sparklies under windows also.

I noticed that the temperature whilst playing EVE-Online (3D game) went up to approx 90-95 degrees and punched 100 a couple of times on GPU 1 - GPU 2 never went above 75. GPU 1 is kinda restricted in its airflow due to mobo design and the PCIe slots being close together, so it gets a lot of heat off the card below it.
My question, is this card ******? or does it simply need better cooling?

(I lowered the clock to 350 from 370 using the Nvidia settings, but didn't make much difference to the temps)

I have just ordered 2 x Artic Cooling VGA coolers for the 2 GFX cards, with the hope to Overclock eventually! but really need to get this sorted out first!
Need to decide if the card/s are broken or just need to be chilled out!

Thanks,

Right here are the errors:

Firmware image PCI device does not match adapter pci device
Firmware image PCI subsystem does not match adapter pci subsystem
Firmware image board does not match adapter board

Error - Board ID Mismatch

If i run it without the switches i get the same first 3 lines but the error changes to:

GPU Mismatch.

Any ideas?
Click to expand...

Should anyone get these errors use:

nvflash -4 -5 -6 xxxxxx.rom

the -4 switch force flashes the card.

Thanks for the info, successfully flashed my XFX 6800GT to the 4001100.rom bios.
 
Just out of curiousity, is there a way that i can display the Temperature of the ram and gpu in the NVIDIA display window? i have seen it on others but not entirely sure how to enable it, my card is an Asus 6800GT 256MB its the full GT, Asus provide one with the CD, but i don't like it too much.

*EDIT*

As there has been no reply, i'm guessing this is either in the wrong place or it just isn't possible, oh well :o

Have you had a look at nVidia nTune?
Click to expand...

That utility only supports nForce cards, not 6800GT, unfortunately.

I use the utility that came with my Gigabyte 6800GT, but sometimes i don't know if it's correct as temps go up to 75C and stay at that temp, even when i shut down all video activity...

If anyone knows another utility that can display live sensor data from the videocard, pls. let me know.
