overclock would be pointless since the ultrabay VGA is already melting ... In theory i could OC higher with Hynix RAM. I have this cooler: http://content.hwigroup.net/images/products/xl/197243/cooler_master_notepal_xl.jpg CM Notepal XL It helps a little bit, but not much. The temp of the ultrabay VGA still reaches 98C, the only difference that it takes a little bit more time to reach it. I've also repasted with Arctic MX-4 and did not help anything.

I see and what about voltage unlock in the 2nd VGA bios? Or if unlock is not possible can you lower it manually and upload a modified vBIOS? Lowering that would help big time. I've posted a factory 2nd 755M vBIOS in your other thread: http://forum.techinferno.com/general-notebook-discussions/1847-nvidia-kepler-vbios-mods-overclocking-editions-modified-clocks-voltage-tweaks-318.html#post78489

I have tested, if the ultrabay FAN was running on max RPM, it would help a LOT. I've ran a game while I started dust removal and until the fan was running on max RPM the 2nd VGA temp started to decrease. Wonder if it would be possible to mod the system bios or 2nd vga bios to force the fan to run on max rpm ... oh and my fan looks like this and it overheats:

It reaches 98C without laptop coolerpad quite fast. I have attached pictures of my fan, GPU die and VGA memory to this post.

I repasted with the paste I've got with my Sager laptop a few years ago, but it did not help anything. I will repaste again with Arctic MX-4, but I doubt it will do anything. Oh and I am using a Notepal XL laptop cooler and it still reaches 98C...

Repasting the ultrabay GPU will NOT HELP...it may take a little bit more time to reach the 97C, but it will. Laptop cooler will not help neither...only way I could think of is to lower the vcore voltage by 80-90mV...too bad there is no probram out there yet which we can use to edit the voltage in the ultrabay VGA bios... Funny thinng is, the ultrabay VGA is cooking inside the laptop., but the fans are not running 100%. If you run dust removal, you can hear the fans running on a much higher RPM. (btw I am on BIOS 3.05)

I've repasted the ultrabay 755M+bought a Cooler Master Notepal XL, but it did not help (at least for the ultrabay vga)...the 2nd 755M much slower, but still reaches 97C and throttles...really need a way to undervolt without performance loss :/

$2,280.00 for an MSI ? That is insane! Too bad the high temp of the CPU and GPU going to melt it ...

Any modified vBIOS for Ultrabay 755M available ? Like for most users my Ultrabay 755M gets 97-98C hot in a matter of minutes with games that uses 99% GPU. A vBIOS for the 2nd 755M with lower voltage (or an unlocked vBIOS that allows voltage changing in MSI Afterburner) would be nice because now the ultrabay 755M throttles for most users because of the high temp ...
