Problems overclocking 9800m GTX on a Toshiba Qosmio X300-13o

I saw that thread and I know how to flash my card.
The problem is I don't know how our cards differ (maybe even physically?) than the resto of 9800m GTX's and therfore if BIOS from other 9800m GTX's will work. If they don't work, the card is pretty much ruined, since we can't backup our card's original bios...

 

This is why we are stumped

 

I know man, but seriously, I CRASH AT YOUR CLOCKS! :S

What drivers are you using with those clocks?

 

186.03 OFFICIAL from nVidia

 

Our 9800M GTX's should be physically identical. Your laptop has a larger 180W power reservoir, and less power output compared to my laptop, which has a smaller 120W supplying power to the hungry QX9300 and GTX 280M, formerly 9800M GTX at 600/1500/900 @ 1v. Logically, your laptop and tuηay's laptop should be able to overclock well above those clocks. Perhaps Toshiba just put in the "Friday cards" in the X300 notebooks.

A big part of me still says that Toshiba did something scandelous to prevent overclocking.

 

Agree here, Couldn't say this better self!

 

I haven't tried it myself on an x305 but ATITool 0.27 b4 was able to write the VBIOS on a Toshiba P100 with an Nvidia 7900GS. Before I found this tool I thought Toshiba locked access to the VBIOS like u guys too. It might work on the latest X series.

On the P100, I wasn't able to flash with the NVFLASH as it couldn't recognise the EEPROM, but I was able to get around it with Phoenix BIOS editor and replace the VBIOS in the TOshiba BIOS and then reflashed the TOSHIBA BIOS, which also flashed the NVBIOS at the same time.

Might work on the Xs's... though... but take care... you can easily turn ur laptop into a brick.

 

Yes, that is a plausible method that I have thought of before. But I feel that is the most dangerous method. If Toshiba is preventing reading and writing to the BIOS using conventional methods, then they don't want us tinkering with it and we should leave it alone. I agree that doing a piggyback flash through the system BIOS can potentially turn the Toshiba into a Toshibrick.

 

lol 10. Char

 

I know they are... as of the cards thingy, they feel more like birthday cards, just without some pocketmoney in them

I still crash, I can't understand how you can run those clocks.

My friend, thank you so much for this info, this might do the trick... although I will spent a lot of time in deep thought in order to decide what to do... But hey, if we I do screw up here, only my GPU is getting bricked eh? (still a pretty costy loss I guess... but at least the rest of the system should be ok)

I dunno, seriously... I've got a card with so much potential here, and it's locked... Crysis would run sooooo good at those clocks... :S

Maybe it's a risk worth taking, maybe not... ARRRRRRGHH!!!!

 

If you screw up the system BIOS flash when replacing the microcode for the 9800M GTX BIOS, you fubar the whole system. I highly suggest you purge your thoughts of these ideas before you get tempted any further, haha. It's definately not worth the minor performance gain.

 

A bit of an update on the BIOS

As Soviet Sunrise suggested the vBIOS are indeed 0617 (well kind off anyway)

Look the attachment

Used the ATiTool 0.27 4b

Supposedly, if not any other part of the system BIOS, except the GPU part are edited and flashed, even if something goes wrong, isn't theoretically only going to affect the GPU? Since the part of the BIOS giving the CPU it's first cycles is going to remain intact, doesn't it mean the system will still be able to boot?

I was just wondering...

 

What I mean is if you flash the system BIOS with an incompatible GPU microcode, you will have a blank screen unless you can blind flash the original system BIOS back, which is more complex.

Sorry if my words were ambiguous, but you will still be able to boot, but it is just as good as dead if you can't see anything.

 

lol... well I get what you mean...

For now, I will update my BIOS with the original ones... Maybe that would have some effect, at least allow me to reach some propper frequencies (after negative feedback to Tosiba perhaps... you never know )

 

lol Toshiba's european website, which has the BIOS is down...

It;s a sign to me that things might go well after a safe bios flash lol

 

I got my fingers crossed for you, my friend.

 

I'm not giving this great chances of success but you never know... lets try...

Even if the updated BIOS allow even a bit of overclocking, it will be fine with me...

BTW I forgot to mention that it seems like the memory clock seemed to not be controled by the BIOS, not surprising though, since the BIOS only deal with the processing elements of hardware (please correct me if I'm wrong)... And raising the freq of the gpu memory had little to now effect with the core and shader clocks unchanged...

 

NiBiTor.v5.0 lets you modify things like clocks, voltages, etc of all start-up 2D, low power 3D, and max 3D modes in the VBIOS.

But nothing you can't do with the std overclocking utils like Nvidia system tools right?

I only resorted to the low-level VBIOS flashing because the video card/memory was dying and I was trying to underclock it so it wouldn't crash the nvidia driver on boot-up.

btw, I heard the Dox's Nividia driver isn't kind to overclocking (ie. with powermizer enabled etc)... you might want to try other newer or earlier driver that is more friendly to overclocking???

Also you might consider open up the laptop and re-apply the best thermal paste/pad to the GPU coz sometimes Toshiba puts too much of the stuff on it and blocking the heat transfer to the heat pipe...
hey... since you're overclocking... might as well get a bit of grease and dirt on yourself
