Bios Modification with Kepler Bios Tweaker (GTX 660TI PE OC)

[yvesl]

Hello,
I bought second hand (2014 jan) a MSI GTX 660 ti PE graphics card, since the purchase this card does not hold the core frequency of origin, so I use MSI Afterburner to reduce the core -100 mhz, with that I have no more crash.
Before modified BIOS with Kepler Bios Tweaker and after:

Same crash if I try 1032 or 1019 Mhz!

I would like to make the modification (down 100 mhz) once and for all in the bios of the map, which I tried unsuccessfully (the crashes were still there), yet the figures of the bios did mark the decline, In short I would like to do without using Afterburner.
I did not touch anything other than the boost clock and boost limit speeds, which I put at the speed that shows me Afterburner in burn (1045 or 1058 mhz).

I forgot something, but what?
Sorry for my bad english.

Thanks for help me.

You modified your bios but never actually flashed it. That said almost anybody here advises against flashing your bios.

Id use afterburner and just have it startup with windows, or make a hotkey for your clocks...

Hi,

You modified your bios but never actually flashed it. That said almost anybody here advises against flashing your bios.

I flashed the new bios with DOS bootable USB key
The card will not go over 1045 Mhz, but crash (whitout Afterburner)

Id use afterburner and just have it startup with windows, or make a hotkey for your clocks...

Afterburner start with windows, but this Video card need afterburner with other computer to work properly, this is not satisfactory.
Thanks

Sounds to me like your card is on its way out, but that said it sounds like you might have messed up the frequency table by adjusting your boost clock. There should be a way of verifying that you flashed the bios, such as a bios signing date, etc.

I have not changed the table of boost clock, to do (limiting to 1045Mhz, actually, max table clock to 1306mhz)?

 

[therealmeep]

Limiting the frequency table will induce your desired results, because lowering the max clock everything else is calculated on will force everything down 100MHz. That said do at your own risk. This is all most likely warranty voiding.

I'm not sure not to have tried it (I tried the modifications, a lot of time, then I gave up, I start again now).
I try this, i come back to say yes or no.

You can downclock Gpu as much as you want to, but faulty card is faulty card, and with lower clocks you will lose performance while problems will remain more or less (i had same issue)

Leave a card in a hands of professional to bake it for you or start saving money for new card

Lowering clocks is just temporary solution for few days (or less)

Put stock rom back in. Take gpu cooler off and replace thermal compound, thermalpads if not performed already, sometimes psu's degrade depending how bad the power grid is there.

No resolution. Replace the gpu

"faulty card" since 3 years and half, if I downclock the GPU As little as 100Mhz (with Afterburner) it work since this time, whitout any problèm.

I'm going to try
But, I down in Boost table, Max Table Clock to 1202 mhz ( 1306 mhz before), it seems to work, whitout loss perfomance.

But problem will be back
I said bake card, if you have professional service to do that
If you cannot bake it properly than start saving money for new card

Bios modification has NEVER rescued Graphics card from certain death, it just extend GPU's lifetime

thanks for your think (full of common sense), but the value of the card is low, and I have no pro who could make this, or very far.
