Now I understand. I had set them manually and they remain in the panel (in other words, they are still set after reboot), but I guess that's no guarantee. Thanks. This makes much more sense now.

Hi,

I had the 7800 GTX working OK at 440/1100 and tried the 450/1100 combination from the ISO on the first post.

It stopped while flashing the ROM and now my new laptop won't even boot !

I'm currently waiting to talk to Dell about a replacement card...

Is there ANY way to bring the laptop back to life ?

I guess it's my bad.

Thanks for any idea !

7800GTX overrides the soft overclock, resets back to stock no matter what you do. Only way to force it is the bios flashing.

Wow yeah interrupting a bios flash is the worst thing you can do to a system, if you can't even get it to post to the bios screen when you turn the system on then its dead, nothing you can do.

Well the way he described it, it sounds like it stopped by itself, I think it's universally understood that interrupting a BIOS flash = dead computer. Though, considering it's on battery backup a power fluctuation seems unlikely the fault. Anyone successfully flashed to 450/1100 using the ISO from the first post? -- for god's sake don't try it now, but if anyone has, that might rule out a problem with the ISO file.

Also, yboivin, which ISO did you use? hammermd's (with the loading prompts) or striph's (with no loading prompts)?

Yikes (throws out disc), sounds like a bad BIOS made it onto the CD. Or some freak electrical surge happened during the BIOS flash... I don't have any suggestions as to what to do next... maybe with some electrical engineering knowledge you could repgrogram the BIOS using another computer, but I doubt it.

I'm having a little trouble understanding this. The System BIOS and VGA BIOS are on separate ROMs. If you have a bad VGA BIOS flash you should end up with a blank screen. However, you should still be able to blindly type the command to flash the VGA BIOS again. Did the computer really do nothing when you pressed the power button, or do you say it failed to boot because you didn't see anything appear on the screen?

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.

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.

Ok, would appreciate some help here folks.

Got the 7800 gtx for the gen2. Installed it myself. First boot after install the screen was unreadable at windows start up. Looked like a TV with horizontal all out of whack. After a few tries, changed bios video setting to reset view size. At least that got me to what looks like 480x680 and useable to load drivers. Rebooted and everything is fine. So then I went to overclock and currently using 91.28 xg drivers, 460/1250, 7462 in
3dmark05. So cool, I have seen higher, but not really concerned about that.

The problem I have is everytime I uninstalled drivers to find best/change another set, I got the same outta whack horizontal distortion. Never experienced this with the 6800 ultra. It would reboot to 1024x768 and look fine ready for new drivers to be installed. At this point, it seems to be more of a pain in the ass than anyhing else. No errors after 2 hrs in ATI tool. Could it be a bios thing? It happened from the get go, before I even started the overclock process. I'm at a loss. Any ideas? Thanks in advance.

ok, so i'm trying to fix the clock speeds on my 7800gtx back up to stock settings because they are below the norm. i have already created the premade .rom files on an .iso disk, from notebookforums.com. now when i try to boot from it, it goes through all the steps until the :r command prompt. it will stop at "unpacking atapi..." and then i have to restart my comp because it doesn't do anything even if i let it sit 10 or more minutes.

any help?

Just did the same thing to my 7800gtx. I tried to flash 450C1200.rom and it stopped in the middle of storing the new clock speeds. I watched it go about 6 dots or so and it just hung there. I let it sit for about 5 minutes, knowing that is was screwed, but praying some how the dots would keep going. Anyway, called dell spare parts and ordered yet another 7800gtx. for 245 plus shipping. I'd rather get another card now than try and go through tech support and it take a few weeks or have them find out it's a 9300 and the cards not supported officially on that model. So, now I've bought 2 for the price of 1 and have learned my overclocking lesson.

WTF! This is disturbing! There are 2 people now with dead 7800 because of this. I've been flashing various roms numerous times, but haven't run into problems, count my blessings. But the ones that I've used are all with memory @1250 just varying GPU speeds. If some of these roms prove flakey maybe the author need to remove them. I for one will throw that cd in the trash now, just going to stick with my current working oc of 440/1250.

Sorry to hear about your card flick. Why don't you try returning the dead one anyways.

OMG!1 avoiding 450/1100 and 450/1200. My 7800 is coming in the next few days, but this hasn't stopped my will to OC that sucker (Thought it does scare the **** outta me)

Im against taking the roms down, but they need alot more looking into

Maybe we should try running these on flash drives. Maybe the CD's got scratched for some reason.
