Hello guys, I have some questions regarding the GeForce GTX 980M. I'm using this card for 2 almost two years now and it's still impressive how much power this card has, especially if you think about the age. I was first using this card in my M17x R4 until I got a M18x R2 for an outstandingly cheap price. I upgraded the M18x with the 980m from the M17x and everything worked fine. As the cooling is better than the 17 I flashed an unlocked vBios(svl7's bios) to get the full potential out of this card. This was working fine for the last two weeks until yesterday. I played GTA V for two hours. Temperature was fine and the card pulled around 110-120w. Then suddenly the screen went black and the overcurrent protection of the PSU(330W Dell/Delta) took place. After a few minutes of measuring I found the GPU, specifically one of the MOSFETs to be the culprit. I replaced the MOSFET with one I found on a K2100M I had lying around(it's the same part, CSD87350D). The card works perfectly fine again and beside the MOSFET luckily noting else was damaged. Long story short: How much can the power stage withstand with three MOSFETs and does it make sense to add the other three "missing" ones? And how much current can the MXM port of the M18x R2 deliver without being damaged?

That was what I thought too, but on the other hand the 7970M seems to work fine without modifing the systems bios(works by using a vbios with enduro disabled). I may gonna try diffrent vbios versions. Found one that seems to be compatible with the clevo d9000f which, I guess, shares software parts of the bios as it's from the same era.

Hello, I have an old Clevo W870CU lying around here for some time now which I got pretty cheap due to a faulty CPU vcore capacitor. I now got my hands on an Alienware M18X r2 with two GTX680M's that I wanna reuse as I upgraded this old boy to a single 980M. I installed the GPU and got the BIOS splash screen and the notebook even booted into Windows. After several seconds I noticed that the indicator lights started to blink while the GPU fan was ramping up to full speed. A few seconds later the notebook shut itself down without warning. I then went into the BIOS and saw that the GPU was recognized as "GPU UNKNOWN". Now my assumption is that the vBios is incompatible and that I need to flash another one(like how it is with MXM in general). Has anyone ever done this upgrade on that notebook and has some experience to share how to get this thing working? GPU Is the Dell GTX680M 2GB

Nice mod! How does it sound compared to the original, working speakers?

I've done that with my 3840QM too. Hits around 90c under full load but is relatively stable and nearly always at 4GHz all core. If the CPU throttles, try to increase the long and short duration power limit. This might help, but i'm not sure about the longevity in terms of thermal stress for CPU and mainboard
