Graphics Card upgrade for M6800 ?

My P5000 arrived. I'm having it installed monday.

 

Heads up to @bobmook. Sorry to only bring this up after you bought your card, but I wanted to make you aware that I've been having BSOD issues and now @JEAMN is reporting the same BSOD with his 1070 as well. (@DynamiteZerg also has a P5000 in the M6800 with no BSOD issues to report.) Hoping to find the cause and a remediation.

Wildly speculating based on limited available information, I think that the BSOD may be more common on the 1070 (higher clock speed); so far the only report of BSOD on the P5000 (my system) has been when an external display is connected to the NVIDIA GPU.

 

If the only occurrence is when an external display is attached it's a non issue for me. The reason I *use* a laptop is my handicap and that precludes using an external monitor In retrospect a 1060 might have been a better option as from waht I have heard those install with no issue,

 

Just remembered that you're on hackintosh/macOS anyway. Who knows what's going to happen!

 

Well I also boot win 10 and Modicia linux ......there are certain things every one of those three do better than the others

 

Well, things aren't working out that great so far.

I got the card installed fine but had to use the x-bracket from my m6100 because the one that came with the 980m has screw posts (?) that are too tall. No biggie, it fits perfect and allows the nvidia heatsink to install just fine - I just had to use a hot air gun to get both to come off of their cards.

I noticed a problem right away when fiddling with Apex video settings - despite the ebay auction's claims that this is an 8GB vram card - it's actually a 4GB card!!

And, to top it off, in different games I'm getting some sort of massive power throttling issue where my temps on CPU and GPU will be 65-70 celsius, but they both throttle *hard*. We're talking down to ~216mhz CPU and <500mhz GPU, for several seconds at a time before it returns to normal. I'm thinking about asking for a refund because of the inaccurate VRAM description on the auction.

Anyone run into throttling issues with a 980m + m6800?

Maybe I should give the Area-51m a try like I was thinking earlier...

 

This sounds to me like some weird driver issue. I *never* had issues like that with my 965m and the two cards aren't very different.........I am also wondering (Given the seller lied abbout the vram) if the card itself is a dud ........If I were you, and I know this would be a pain.....I'd get a return on the card and try a different 980m because what your describing isn't what should be happening edit....I did some further research and the 980m can consume up to 120 watts whereas the 965m just draws about 70 ........I stand by my advice to return the card but I might back down to a 970m or a 965m given that I understand these machines weren't really designed to provide more than 100 watts on that bus .....

 

Yes I double checked and a 970m is at the 100 watt level

 

I think in this case you should seek out another vBIOS to try. I believe that throttling is handled by the vBIOS. Also I have recently read at least one story about a card that had its RAM amount capped by the vBIOS that had been installed.

 

Aaron is my tangible idol when it comes to this upgrade mess and you'd be well served to follow his advice
