Как я понял что программа Throttle Stop на процессор , но ниодна утилита не определяет что процессор сбрасывает частоты, он всегда работает по максимуму, но без утилиты все тормозит, с утилитой все работает.
Вот с забугорного сайта цитата- но там хоть подключение определялось в MSi GT780DX- но не работало НДМИ. (ноутбуки вроде на одной платформе)
"So I replaced the GTX570m in my MSi GT780DX to a Dell GTX675m and everything works perfectly EXCEPT for the HDMI port. VGA works fine. But the thing is, there's never any sort of error message or notification, no "Device not recognized", etc. Anything plugged into the port just won't show up. No "You plugged something in! : D" sound effects, so it's more like it's just pretending it's not there. Before I give my hypothesis, here's what I've done:
First off, I have Windows 7. In preperation for the GTX675m, I removed the graphic drivers (using "add/remove programs" and "Driver Sweeper", carefully following an instruction set, so nothing gets unnecessarily removed) for the GTX570m, opened the laptop, cleaned and repasted where necessary, installed the card, booted the laptop, installed the appropriate drivers, rebooted. Tried out some games on it and as expected, it throttles constantly, but it functions! Anyway, I hesitantly proceeded to follow Xonar's instructions to utilize his modded bios (retrieved the appropriate version, made a bootable flash-drive, etc). Works perfectly. Installed and activated ThrottleStop to stop throttling (hurr). That works too! :3 By then I noticed an issue with my HDMI port. I can't recall all of the methods I attempted to get it to at least realize that it exists... Reinstalled graphic drivers, went through Nvidia control panel and tried everything necessary there, tried Fn+F2 (for this particular model, that's the "connect to a projector or external display" function). Tried different monitors, I know the cable works because I still use it for other things, I searched for it in Device Manager, tried refreshing for hardware changes, changed some seemingly relevant options in the now extensive bios. One of which was enabling on-board graphics, which I knew would most likely result in a blank screen. It did, so I looked up a picture of the bios to find which function key restored defaults. Blind-booted into bios and restored defaults, works fine. ... I'm sure I tried more, but I can't remember.
I suspect it has to do with the new Bios options and I just don't know for sure what it is. I'd rather not kill my computer or spend hours looking up what all the abbreviations stand for just to find it's not the solution. No, I haven't flashed the Vbios, GPU-Z will even tell me that the sub-vendor is Dell. I very much doubt that's necessary anyway. I really don't want to get into anything else risky unless somebody reputable and very knowledgeable on the subject tells me that it's definitely the solution.
Thanks in advance for any help! I REALLY hope to get this fixed. VGA streams 1920-1080 but doesn't look as good and I'm down a display."
как он пишет что все заработало
"Alright, I finally stopped being lazy and flashed my GPU with SVl7's .92v MSI GTX 675m VBIOS and everything works just fine now! I know this is an old issue now, but I just wanted to thank everyone for their help. : D And I'll hand out rep where I can."
