I've got an E1705, and my BIOS won't unlock. So I'm stuck using NiBiTor to hard-edit clock speeds. What do you think I need to do? Also, red dots and flickers means too much overclocking, right?

What is up with "750MHz" for mem speeds, I see alot of people say their 7900GTX freak out just for that number speed! When I had my 7900GTX I had it running for the longest time at 625\750 untill I updated from A02 bios and put Vista on it, and i wish I had left it at that then, Well time goes on Sold my 7900GTX for the same price I Bought my 7950GTX and same thing, with that card if I try to use 750 on memory it does the same thing with colored lines across the screen, and I have had it at 800 but a get a Nv something.dll error sometimes and vista reports card stopped responding so 775 seems to stay ok, which is strange because as soon as I unlocked the card I had set it at 650\800 using G Tony's 163.44V2 drivers, and I had to reformat and since then I cant get those speeds again, card stops responding, but not all the time and on certain games. If I didnt know better I'd swear Dell's 7900GTX and 7950GTX are the exact same card with different bios, thats it. I sometimes wondered if i tried a -4-5-6 flash on my old 7900GTX w\7950 bios if it would of worked? Because going from a 7900GTX 625\725 to a 7950GTX 650\775 wasent a major upgrade, for the time, luckily the money was the same.

After I`ve reinstalled the to the subject video drivers my temperature btw monitored by RIVA TUNER dropped down from 54 idle to to 44 idle = 10 degree difference
Quite frankly I `ve never heard about anybody accomplishing thermal drop by using different drivers. Could you, please, someone confirm or deny the possibility of this happening.

Tnx a bunch, LtR

In my case I have ForceWare 156.83 and the temperature in the driver panel 10 degrees lower then in ATITools. Which one is right one then? lol

I run 169.04 and my idle temps are between 48-54. Heavy gaming temps are 85C (ATI Tool).

Updated several links, and cleaned things up a bit.

Hi, sorry this is a bit long-winded, but I desperately need some help!

I have a 9400/E1705 with a 7900gtx (Vista 32-bit). I thought I had fried the memory on it after using it with a stock 90W adapter and T7600 and getting BSODs with Memory Parity Error when playing games or even running the Vista performance metre thing. After trying everything (apart from a re-format), I bought a new card.
I installed this with the NBF 169.04M6 driver (which I was also using with the old card), and all was fine for a while until the lower half of the screen suddenly started flickering when using a game editor (as did the previous card before getting a BSOD) . Rebooted, and the screen had dashes, lines, etc across it and was unable to boot into Vista unless in safe mode. Tried uninstalling and reinstalling drivers, then reformatted and reinstalled Windows, but couldn't complete installation since the display didn't respond, as before, when entering Windows. Since the same dashes, lines and commas remained during intial boot-up I'm assuming that the card is dead?
Have since put the old card back in, which at least powered the display and was fine for everyday stuff. Installed the same NBF driver, and when Vista loaded and ran the performance metre it got through it fine (it used to crash previously). I therefore tried running the game editor (enough to crash it previously as well) and ran Far Cry, with fine results for a few days. Today, on reaching one slightly-more light-intensive indoor patch in FC, the lower half of the screen went berserk again flickering, as it used to do. Ran FC a bit more after a reboot and all was fine, though I switched to lo-res for the indoor bit. Haven't pushed it otherwise since, but am not sure what to make of this. Is it the driver or is the memory truly dead? Am also puzzled by the "death" of the second card (which I still have).

Any help would be greatly appreciated. Have wasted so much time with these stupid cards that I want to chuck the laptop out and build a PC!
Cheers!

Did you try to change the driver and run FC on the high settings ? Make sure that you clean leftovers from the Video driver before you install new one .

If thats not helping - then overheating I guess ??

Will try a different driver with the original card. I tried everything with the second one :-(

I am sorry for you.

I have seen the exact situation on other video cards from Dell and I can safely say you are pretty much screwed.

If you say the lines appear from the boot screen it means you can try whatever driver but the video card will not work the same.

Usually your problem is caused by a bad memory sector and there is no way to fix it unless you get a new video card.
