A very big thx to @svl7 who sent me a new Bios-chip! Notebook works again after one month being a brick.

Thank you very much

@svl7: Do you solder the chip out or can you fix it via Jtag?

Hi, danke für die Antwort! Darf man hier auf deutsch schreiben?

Ich weiß ich bin einIdiot aber da ich die Karte undervolted habe und sie gleichzeitig minimal übertakten wollte habe ich immer ein SPiel gestartet gemerkt es geht oder geht nicht, mit RBE Bios geändert, nuestarten in dos, bios flashen und wieder hochfahren, da ist es doch um einiges bequemer das ganze in Windoof zu machen, aber es war mir eine Lehre und ich werde es nie wieder tun!!!

Ist es möglich die Karte in einem anderen Laptop mit interner hd3000 oder 4000 zu flashen oder in einem mit crossfire?

Und lötest du den Chip aus oder flashst du per Jtag? und falls per jtag würdest du verraten wie du das machst? Würde natürlich auch etwas für deinen neuen Laptop spenden!

Hi

With the 13.4 drivers I were able to modify my bios.

I did that 10 times under dos and then i tried it once with atiwinflash and it failed!

The screen stays black and it won't boot from any device (USB, floppy, HDD, SSD)

Is there a kind of crisis disk for Clevos because I already tried the Crisis disk with Fn+B, Fn+ESC and Fn+F but it won't even start when I press Fn and I tried to blind flash but it seems that I can't boot from USB or floppy without working gpu. I think it gives out an error before boot from any device would be possible.

Thanks in advance

First of all thanks for your help Aikei but I solved the problem by myself! It was the driver! With 13.8beta it did not work but with 13.4 stable it does! Undervolting and overclocking works fine Thread can be closed!

OK I think you are deeper inside that than me but i don't understand why it works at other people without any problem and not at my card

What are the " adjacent values"?

Thx again! I will try your version! Have you changed the values with Radeon bios editor or another program or directly with hex-editor? greetz

Thx for your help but it still runs on 1.1 Volt. Has anybody else an idea why i can't undervolt or overclock my card via bios?

Hi All P170sm do have two 2,5" inch sata and two msata slots which can be used for msata SSDs You can tweak your prcessor with "Intel XTU" but do you really want to overclock a 780M? I think that's absolutely not necessary and in worst case you are loosing the guarantee greetz

Hi

Thx for your answer!

Bios0 is the original one Bios1 is the modded one

Hi

I am new to this forum but not completely new to flashing.

My probem is I flashed a (by myself) modified vBios on my 6990m in my P150hm (Subvendor is Dimotion) but it doesn't have any effect.

I read it out with atiflash in dos, then modified it with radeon bios editor and flashed it agaoin with atiflash in dos. without any errors.

I wanted to undervolt it to 1.0 Volt at 715/900 but it still runs at 1.1V (overdrive is deactivated)

I also tried to overclock it to 730/930 with 1.1 Volt just to see if it works but unfortunately it does not!

Gpu-Z shows me the raised clocks but it always stays at the standards even in games(715/900)

Has anybody an idea what I am doing wrong?

Bios is the latest downloaded from the schenker homepage (EC13 and Bios14 I think)

If anybody needs more info please leave a reply

Thanks in advance!

Hi@all

I found your forum while I was looking for a solution for my 6990m vbios.

Very nice forum and it seems that here are very competent people!
