Ok Do you have any place where I can download your BIOS with EC V 1.03.06 & BIOS V 1.03.05, Ffor the meanwhile? i think i ll send the computer to warranty in september

Greetings Prema, any advance in this? The stock Bios(even the older ones above EC V 1.03.06 & BIOS V 1.03.05) have the some Pwr Throttle problem with the 870m. Thanks

That's my vbios. Thanks Vbios.zip

It is giving me a lot of artifacts on games :/ Maybe the clocks are too high?

Hi Klem can you please give me your overclocked vBios for my Clevo P151SM1-A with a gtx870m? Thanks

Tried again as you said. Powerserverbios doesn t appear on task manager services tab : /

That 870m Vbios didn t solve the problem, only add another one. Had to downgrade to my previous bios to solve the problem.

Hi again prema, after I installed your BIOS (P15xSM-A BIOS 311 EC 308) on my P151SM1-A) it seems I have problems with the TDP of my gtx870m, as you can ser on the this imagem. http://gpuz.techpowerup.com/15/07/25/ef3.png Everytime i lauch a game(i have tested Witcher 3, dota 2 and BioShock), it is barely playable, as the memory clocks drop from 2500 to 2000. I have already set my windows to high performace and set on NVIDIA controle panel prefer maximum performance. I have already installed the stock BIOS of my manufactor, but that didn t solve the problem either. The previous BIOS version i had was BIOS Version: 1.03.03 KBC/EC Firmware Revision: 1.03.04 I never had problems with it. Hope you can help me with this, thanks in advance.

Greetings, I´ve just flashed your gtx870m vbios on my Clevo P151SM1A and when i start a game(witcher 3 for example) the image freezes forever after 5-10 seconds, but I can ear the sound of the game, even the sounds of my actions in game, which means I'm still playing. I did't make any change with graphic card, just installed the vBios. Can someone help me with this problem?

Is it possible to control Gpu Fan Speed with your Bios in my P151SM1A? Any update for that clevo model scheduled?

Greetings, Yesterday i flashed the Prema Bios on my Clevo P151SM1-A with a gtx 870m (https://biosmods.wordpress.com/p151sm-a/) and since then i'm experiencing inconsistent framerates on games, especially on Witcher 3. When the temperature reaches >70ºC the Memory Clock of my GPU drops from 2500mhz to 2000mhz causing a slowdown(framerates drops from 30 to 20-22) in order to maintain the temperature below 70ºC. The game runned locked@30fps with temperatures between 80-85, before the BIOS flash. I've updated the Nvidia drivers and didn't worked. After I unnistaled them with DDU and installed a older version and still nothing. Already tried to go back to stock Bios, but GPU still throttles at 70ºC. The last thing i tried was format my HDD and reinstall windows, but that didn't worked either. Don´t know what to do anymore photoupload
