All reseller use the same BIOS apart from a couple of visual tweaks...my v2 Mod is based on v1.03.04

In this case I'm not sure. The bug was there on bios prior to 1.03.01 and is there as well on your older mod (so 1.03.03). Funny thing is that is also driver dependant (with VGA drivers prior to 13.6 it won't kick in).

I don't really know if the problem is only of a few people and is given by some strange software/hardware combination.

Yeah I don't know if the new vBIOS works on P1xxSM, too.

The latest Mod wouldn't make a difference to latest stock regarding this matter, so using the Mod won't hurt it.

Well, I don't know if the reseller modded the bios somehow to avoid this bug. Older versions of their bios had it as well as your v1.1 mod (that is based on a newer version).

So I don't really know if the fix is something specific for the 1.03.01 bios or if they modded somehow the bios to avoid it.

If it could be of some use I will send you via PM the 1.03.01 bios I'm currently using.

Especially downgrades are dangerous. They work to a certain degree. In the case of your model you would kill it by downgrading to a pre v1.03.xx BIOS/EC.

My Mod doesn't change anything regarding dGPU on that model, what 'problems'?

I already posted it a while back. Under certain circumtstances a bug kicks in and the GPU goes to 100% load even under light load.

It doesn't have an impact on performances but the heat generation is horrible.

You told me that probably an update of the GPU bios would make the difference but I couldn't find any newer bios for my 8970m that was tested on enduro machines.

The ones in the OP are from machines that don't have enduro and if you open them with VBE you'll find out there are differences with the UEFI boot sectors so I won't take the risk to flash them.

I guess I'll just live with my fan noise for the moment.

Never flash any old backups! The risk of bricking is very high.

This includes going from an newer to an older version of the stock bios?

Last time I tried your mod I had problems with the GPU, I flashed the stock 1.03.03 and then my reseller 1.03.01 without any problem.

I've just been lucky or is a safe procedure?

To be honest I'm pretty much ok with my stock bios, I just would like to use the more aggressive fan profile to avoid the full speed fan to be forced even with medium loads.

I'd try your new mod but if still gives me problems with the GPU I would want to be able to revert to the old one safely.

edit: I forgot: I'm on a p150sm

Just to reply to myself that may be useful to someone else: I asked on an italian forum to someone who has just received his P150SM with a 8970m for his vBIOS version and he has the same bios as me (0.15.032.000.003.044465 (BR44465.003))

So... I won't risk updating the vBIOS of my GPU since newer ones are not proven to work on Enduro setups.

...

Clevo has pushed updates for P37xSM and P570SM. They are in the OP, but I am not sure if they work on the Enduro P1xxSM. There is also a v007...

Which version are others using with P1xxSM, any experiences here?

Anyone? I'm also asking on an italian forum but I had no luck for the moment.

That's the shipping vBIOS. Clevo has pushed updates for P37xSM and P570SM. They are in the OP, but I am not sure if they work on the Enduro P1xxSM. There is also a v007...

Which version are others using with P1xxSM, any experiences here?

Probably update the vBIOS is a good idea (still: I wouldn't take the risk to update it with something that isn't specifically done for Enduro machines) but with that vBIOS the card works just fine as long as I use the Santech's 01.03.01 BIOS, so I guess that at least there is the possibility to have a workaround.

The BIOS has all the 8970M fixes, but you may have to update the vBIOS, too. What is the current version shown in GPU-Z?

GPU-Z reports 015.032.000.003.044465 (BR44465.003) as Bios Version

Hello Prema, first things first:

-Sorry for my bad english

-Congratulation for your work, people like you give a greater lifespawn and value to everything they work on, so thank you.

Today I've tried for the first time your bios on my P150SM, I really loved some of its features but I couldn't help but notice a bug with the AMD video card.

Under certain circumstances (for example using the latest drivers and starting Adobe Photoshop or changing resolution of a game) a bug will trigger and force the videocard to 100% load even in idle; there won't be problems performance wise but the GPU will get very hot and force the fan to ramp up even for very light loads.

This is an old problem that sometimes comes back, the italian reseller (Santech) of my Clevo solved it with a firmware update to 01.03.01 (as far as I know it should be the stock Clevo firmware, just with a different logo).

I'll give you some more informations about my system and what triggers the bug:

OS: Windows 8.1 (but the bug shows up with 8 as well, I don't know about 7)

CPU: Intel i7 4700qm

Ram: 2x8gb 1600mhz DDR3L

GPU: AMD HD8970m

To reproduce the problem you have to:

-Have an AMD driver older than 13.6, from 13,8 beta the problem is always present.

-Have ULPS (amd ultra low power state) enabled.

-Start certain progrems (Photoshop is one, but also Borderlands 2 splash screen gives problems) OR change video mode (eg. change the resolution of the game or switch from fullscreen to windowed mode).

I don't know if this can help you out but with the working bios I noticed that when the dGPU is off afterburner reads certain values to the max possible (511°c for temperature, 200% for load), while using any other bios it reads 0.

I'm certain that the 100% load problem is not just a reading error bc of the temperatures.

If you wish I'll pm you the older (bug affected) and new (bug free) bioses from the italian reseller; at the moment I switched back to the original firmware because of this bug.
