Generally computers that aren't designed for "headless" operation won't boot without a functioning video card. So yes, a bad video flash will render the computer totally unoperable.

Hi!
Could you include 1300MHz (or more) for higher clock speeds?

Bumb.
Ok. I'm an idiot.

What's the EASIEST way to get a good clock with this? I read about some of the flashes not working.

I"m currenting getting 66xx. I would REALLY like to get a min of 7500.

This needs to be REALLY simple.... I'm an idiot,remeber?

1) Download this: http://www.ldb4.com/7800BIOS.ISO
2) If you don't already have a CD burning program download this: http://static.slysoft.com/SetupCloneCD.exe
3) Put in a blank CD-R or CD-RW media.
4) Install and run CloneCD, click the button that says Write from ImageFile, select 7800BIOS.ISO and continue to burn the CD.
5) Reboot, hold F2, select boot from CD drive.
6) Hit enter until you are given the R:\ prompt
7) Type dir /w to see a list of the BIOS files on the CD. They'll look like 425C1200.ROM etc. You'll want to start off with something moderate like 425C1200.ROM before moving up to higher speeds.
8) Type nvflash (name of bios file.rom) and hit Y. For example type 'nvflash 425c1200.rom' without quotes to flash your BIOS to 425MHz core clock and 600MHz memory clock (DDR doubles that 600MHz into 1200MHz effective speed -- just a bit of technical info for ya).
9) Reboot (hit Ctrl-Alt-Delete), run ATItool and do an artifact scan for 5-10 minutes or so and make sure it doesn't get any artifacts. It should say 0 artifacts in xx:xx minutes which should be the same length of time since you began the test. If you get artifacts the two times will be different and it will also briefly say something about 'delta of xx' meaning it detected artifacts. If you get no artifacts you can safely go up another clock speed so reboot and repeat steps 5-9 until you find a comfortable overclock for your machine. Once you get artifacts in ATItool, back off 5-10Mhz on the core clock and use that.

If you want to go back to the original (stock) clocks, type nvflash original.rom at the R:\ prompt.

Now your talking!
Thanks man!
I started off with 450/1200 ....couldn't help myself.
I've got 15 minutes in ATI tool so far....no errors.

Thank you Thank you Thank you REP POINTS ++++++

Just for you 3Dmark whores

I get about 200 more points using the extremeG version of the driver, compared to the laptopvideo2go version

cheers

The damn extreme g version could n't make it through 3dmk05 without any oc on my machine... I also had a tough time installing.....(took three tries). Laptopvideo2go took my 3dmk score down 30 points from the getgo from crappy dell drivers.

OK, NOW ON TO THE GOOD STUFF
Here are my results...I think yall like to seee these?
450/1200 stable for 15 mins in ati tool and scored 7300 in 3dmk05 with normal startup items(5% processor usage)
450/1300 artifacts
510/1250 art
480/1200 errors
465/1250 good for 5 mins in ati...then artifacted...86 degrees
460/1250 errors
460/1200 stable 16 minutes staying here for a while tired of testing for now runs at about 90 degrees in atitool 7424 in 3dmk05

If anyone has any suggested numbers to try I'm willing I'm just not sure which way I should go from here. I don't feel like 8k is a possibility without a major processor upgrade or some better drivers.

I think 460 on the core with no artifacts at default voltage is good. If you're feeling adventurous you can increase the voltage by creating your own BIOS using Nibitor, up the "Voltage ID" to VID 7 and you'll be able to bump up the core and/or memory clock a bit more without artifacting, but it will run a little hotter.

The instructions on how to do that are around here somewhere. I'm sure you can find it. edit: link in my sig "VID 7 overvolt"

edit: however it seems you're getting artifacts with minor OC on the memory? try running a low core but high memory like 425/1250 or 425/1300 and see if you still get artifacts... If you memory doesn't overclock well on this card you might want to try the other one.

I'm running various speed checks now.

Thus far, I've gone from 445/1250 to 450/1300 to 460/1300 (running now).

Scores from stock to current are (using the 81.95 drivers from LaptopVideo2Go):

High Quality Runs
Stock: 6533
445/1250: 7281
450/1300: 7386
460/1300: 7459
470/1300: 7524

High Performance Runs
450/1300: 7508
460/1300: 7604
470/1300: 7673


Is there any way to get you to code more bioses with higher RAM speeds? I think there might be some more headroom to play with, but all the ones you have on the ROM are limited to 1300 on the high end.

Excellent work, by the way.

I stopped at 470/1300, not because I had problems, but because I wanted to work core clocks up with the 1300 memory (or greater).

Should have noted what I have, eh?

XPS Gen2
2GHz Dothan
1GB RAM
60GB 7200RPM HD

Added image validation link for high score.

In an attempt to create the current state of bootable CD that's listed here (both of them), I seem to be failing miserably. Anyone have any suggestions on how to get this to work properly so that I can add my newly modified bios files?

I used WinISO trial version to add my custom BIOS files to the bootable CD image 7800BIOS.ISO. Worked just great.

Yup, just figured that out and did the same thing. Here goes nothing with my new files and speeds.

if u have a thumbdrive, and a nifty little program call HP Drive key, I have all of the Windows ME boot files, you make ur thumbdrive bootable, and just use that. It sure as hell saves alot of CD's, and it is alot easier to edit a .rom file, reboot, change it again, reboot try that. Instead of attempting to figure out which .roms u wanna play with, find out they dont work, waste another CD, yadda yadda yadda....

The orginal.rom does not work. I'm geting a i/o error. What kind of alternatives do I have? What are teh stock clocks on this card?

Stock clocks are 400/550. You can try the first post in this thread's link to see if the original.rom is working with that one.
