Hey guys... I'm in modding mood, again, hahaha Got my hands on a Nvidia 470m and put it in a G73JW. Unfortunately Windows won't boot.... "Valid MXM structure not found". Does anyone of you have any idea about this? Every idea is greatly appreciated. Here's all the info of the card that nvflash gives me: Btw, I'll try the 6970m again later, maybe I messed up something last time... I mean it did boot with the 6970m...
I'm in modding mood We (me and a friend of mine, G73JW owner) just put a 6970m in the G73JW to see whether it works. The system POSTed and loaded Windows, but unfortunately the screen stayed blank Some background infromation about this whole story... When I exchanged the CPU of this machine a couple of weeks ago I decided to take a look at the GPU as well, as the system was already disassembled. (Note, it's a real pain to take apart this machine... totally unlike the AW systems... you have to tear it down completely, take out the mobo and then turn it around to get access to GPU/CPU...) Anyway, the GPU has nothing to do with an MXM-card... except for the connector which seems to be the same (at least physically, I have no idea whether it's the same electronically)... but see yourself: As you can see, the connector is physically identical, but the die is positioned differently than on a standard card... As the G73JH has the GPU at the MXM-conform place we got a heatink of the JH model. After some cutting and grinding it did fit the 6970m. The problem was that you can't fix the card with screws since the holes of the G73JW 460m are at totally different places... but that's nothing a little bit duct tape cant fix The important thing is that the heatsink can be screwed on very well. But well, like I said, it didn't work... a couple of hours work for nothing. So we had to disassemble the system one more time to put the 460m back, lol. I knew the chance of the 6970m working was small... but since the G73JH (5870m) can run with a MSI 5870m as well, I thought it's worth a try. Maybe it's only an issue with a hardware ID, I have no idea... like I said, POST was fine, system booted, but screen stayed black. If anyone of you have an idea to get it working, let me know! There are two more pictures as attachment which show the 6970m on the mobo and in the system, if you're interested... just as "proof"
