- Nikey22 for the win!
The macrumors forum has been updated, there is a vbios available to flash the nvidia k4100m to work with the 2011 imac for a gpu upgrade. Now, the 27 inch iMac is going to be the best option here, because the k4100m is a more powerful card that has a tbp of around 100watts, which is similar to the radeon 6970m that shipped in only the 27inch iMac.
Best for the 27 inch iMac, because it has a power draw of 100w
Page 288… but there is a link to the bios within the Mac rumors main page.

Running about $89 on eBay at the moment, which isn’t too bad of a price.

Cool, cool. Great seeing the news being passed around, long live the a1311/a1312 iMac's. One of my favorite Platforms ever created by Apple.
just finished upgrade, workin great so far! Thanks Curtis
Were you able to install Mojave or Catalina and use it without any issues?
Curtis, I recently purchased three components off of eBay for my 27" 2011 iMac, based on the excellent MacRumors thread you turned me on to, as well as your videos covering all this stuff. I should receive these three items this coming week and I am quite excited to install them, and then learn to flash the vBIOS using the Linux stick method. Below is my MacRumors signature line, so you can see what I have and what I am going to install. Thanks for the great videos. I have learned a lot from you. I will soon be bugging you for help, too, heh, heh…
iMac 27" Mid-2011 - 3.1 GHz Core i5, 32 GB DDR3 RAM, Radeon HD 6970M, 1 TB HDD, 480 GB SSD
Just Purchased: Nvidia Quadro K4100M, Intel Xeon E3-1275 3.4GHz, Broadcom BCM943602CDP
How did it go? Got the Wifi/BT card to work with the GPU?
this channel is small but mighty
Glad you are enjoying it! Question for you - what types of content would you like to see more of?
Curtis Gross your tutorials are really awesome and a bit relaxing to watch. videos like this are really cool and helpful too. the production work on these are really punching above their weight and holding their own with bigger channels. honestly i don’t mind what kindof mac videos you make, i’ll watch just because i like them.
I wish I had bought a 27 instead of a 21 from 2011 now. :(
Thanks for the info Curtis, I bought the last one K4100m in eBay for mi iMac 27" 2011...
Alejandro Luis Paolucci nice!!
Thanks for the update. I hope there are some left!
They have been going in and out of stock around that $90 price point. But now I am seeing the k610, k1100m and k2100m coming back in stock as well!
@@alejandroluispaolucci6134 that's coming in at $299 now. Others at $149
@@MrPaw45 where are you finding them?

@@MrPaw45 thanks 😊
Thank you for your videos/work !
No problemo!
WAITING FOR THE VIDEO IN THIS NEW UPGRADE......Thank you...Thank you.
I did a new video with the k2100m... the k4100m I was eyeing at ~$89 sold out immediately and the prices have not recovered haha!
Hahaha glad to see this! Purchased the same exact one after seeing your last video on the k610m. Im assuming the steps are the same?
Roger Grand-Pierre - looks like all the steps should be the same!
Hey Curtis! Any chance you could do a video on upgrading the Wifi/Bluetooth Card on the 2011 IMac's? They seem a bit complicated in terms of installation. Thank you sir!
@@messing-with-computers so i finally installed all the new hardware, heard the chime and fans but the screen never turned on:-( . Back to opening her up. Any idea where i went wrong?
I just bought a flashed K1100m for my 27" iMac. I'm hoping I can change it without taking the entire motherboard out.
Curtis - thanks for your helpful videos! I have a mid 2011 iMac 27”, and I want to do the GPU upgrade to something more powerful. The flashing process sounds painful. You have any flashed GPUs laying around you’re willing to sell?
Hi Curtis, I really like watching your videos! I would like to try this card on my iMac but today I fell infront of a K4000M with half the price. Is it possible to make it work as the K41000M? I tried to find an answer in the Forum (Macrumors) but without luck.
It works from what I know, but not as well as the k4100m, so do try to get that one.
How did you make out with the K4000M, did you ever try it?
@@nelsondog100 No I ended up buying a K4100M and works really nice!
Hi, Curtis. I think for much people will be interested what is latest in 2022 best GPU for iMac 27 2011?
Короч подписался, если кто из Питера - велкам на апгрейд
hi cool video, could you advice which solution give me better performance on 27 imac 2011.
I thinking about egpu probably RX 580 or upgrade internal gpu on K4100M, (I am litle bit worry about vbios flash)
i want to upgrade at least to Catalina and computer use mainly for video editing, working windows in bootcamp will be benefit too.
thank you
I managed to get my hands on a cheap K4100M. And today I have successfully flashed it in my iMac 2011 27''. There is just one problem. It seems that the brightness (display is kind of dim) is not as with the stock GPU. Do you have any useful information/tutorial for that issue?
is this the best option for a 27-inch, Mid 2011? I've used the iMac for years and the video card finally died. I don't want to spend too much $ in it but I miss it so much!
formatC2 either the k610m, k1100m, k2100m or this card will work
The answer really depends on what was the original card installed into your iMac? If it was a 6970m you'd want to stick with a MXM-B card such as the GTX780M/860M/870M/880M/k3100m/k4100M/K5100m ETC. If your iMac shipped with the 6770m (less likely to die, but we have seen it) then you're looking at the k610m/k1100m/k2100m as these are all the MXM-A sized cards that fit your Heatsink.
You could also buy a dead 6970M card with heatsink off eBay just for the Heatsink.
@@highvoltage12v could you provide a link to the purchase? k4100m I want to buy.
donde podría conseguir mas actualizaciones? tengo una k5100m pero en la pagina oficial nada que actualizan
I love your videos and subscribed! I can’t find info anywhere about this. Will this work on iMac 27 mid 2010??? Does anyone have any kind of info on this???
hi, fine to use any brand of nvidia k4100m? thanks
To anyone who knows about the actual physical placement of the 4100m into a 2011 (27"3.4/i7/6970 baked back into service for 7 months). On a different iMac I had a 2100m put in by a nerdier guy than me and it's been solid for nearly two years and runs a Thunderbolt Display, so I want to see about this i7 and perhaps shoot higher still. And on the one in question, I have taken things apart and done the baking and rebuild myself. Are there any physical mods (filing/grinding/adapting type stuff) to know about, and maybe a 4100-specific tutorial if there is one?
I'm also pretty well versed in OCLP. The iMac in question is just one of the machines I have using it (Big Sur) and I've done several more. It looks like the end of the line for Kepler GPUs with Monterey 12.5, but for an iMac so far out of support, that would be a huge extension of lifespan.
At best, my demands for the iMac would be amateur video work for music or orgs, personal stuff, etc, and Logic. I know Logic isn't a demand on the system so better to just say I could use it for the video stuff and hope to have something more robust than I started with, and not prone to dying anytime soon.
soooo, can you fit a replacement PSU for a 27" into a 21' and then use those higher end GPU?
Hey Curtis, thanks for the helpful video! I finally got time to install the K4100m GPU today... Everything went smoothly, including the vbios flash. But my iMac would not start after I put everything back together:-( It would chime 3 times quickly... with a black lit screen. Any idea on how I should debug this. Thanks!
After getting the original gpu reinstalled, the iMac boots up without any issue. I guess the vbios wasn't updated properly...:-(
hi and thanks for your work.mac rumors has been updated and they have announced that k5100m is also supported.it's a huge upgrade.8 gb of ram and more powerful than k4100m.what is your opinion about k5100m? do i go with k4100m or k5100m.they are almost the same price
The only rumor I have heard is that the k5100m can hit the thermal and power limits and shut down :/ So, my play would be the k4100m
@@messing-with-computers thanks for reply.what about 880m? so you mean, we cannot go with every card listed in the rumors site, only because they have written bios and all that stuff?!? because i've heard that maxwell cards like m4000m have been tested by some guys, although they loose the boot screen, but it is very powerful than the listed ones.is there any way to increase the cooling capacity so that we could use higher end cards?
@@codingwithmassodpersiancha2100 - I haven't seen any successful Maxwell conversions. Just Polaris cards. I think this comes down to what Macs supported natively - there was never a Mac released with a Maxwell based Nvidia card ever... but there was Kepler from Nvidia and Polaris from AMD in other models.
i have flashed the bios and the boot screens work but when ever i try to boot into mac osx i get a black or white screen, windows 7 works but only as standard VGA adapter... the flash worked but its not working ARRHGGHGHH!!!!
Is this GPU compatible with the iMac 27 i7-860 2009? Is it too much of a hassle to install?
If the concern for the 21.5" models is the lack of power from the power supply, what's stopping us from modding in a power supply from a 27" iMac model?
Only the size of the power supply. The 27 is bigger in size and power.
@@messing-with-computers Interesting, so then in theory... If I can get the upgraded power supply to fit, it will work without any issues?
Dre C - it sounds like an interesting project for sure. Double check that the power cords on the inside are the same!
Are there any other cards that can be placed in this machine?
Would the K4100M work in a 27 inch Late 2009 iMac?
yup, that's what I have, well, I have the custom one which then became the 2010 model, but the only difference is the i7 quad core, so i bought a caddy to put two ssds(already had an ssd and the 1tb drive(ssd dangling behind the optical drive), and 32GBs mem, and a 3pipe cooler. This was around 230£ cost total, so maybe 260 USD.
Can I flash the vBios of my gtx 765m with only my imac 2011 21.5'?
Yup! I would leverage a linux bootable USB stick and SSH in from another device and flash the vbios that way (could even use a phone if you download a terminal client). You can use windows as well, if you install 'teamviewer' before installing the video card. The tricky part is that while MacOS will boot and show the screen, linux and windows will not until they are flashed...so you have to do a 'blind boot / flash.' Check out my 2011 imac with brightness and boot screen video for more details.
Do not ever install an MXM-B card into an MXM-A only 21.5" iMac, unless you want an unstable system with random reboot. I've done all the experimenting there is with the a1311 platform. Nope.
Will this work on 2011 Imac?
what would be the best card for the 27 2010 model, can the same card be used?
If you have an i3/i5/i7 - you can use the same list of cards.
The K3100M rom has been released and since your iMac is a 2010 model, it might be a better match. They are a bit cheaper on eBay too.
@@highvoltage12v I have the same 2010 iMac. So this would probably be the best card to install? The fastest most compatible for my machine?
K 1100?
Will this be better than the 765m for a 21.5 2011
Edison Chow - I wouldn’t use this for the 21.5, the concern I have is that this has higher power draw than the 21.5 can handle. So the 765m or k2100m is a better choice.
plz bios k3000m
If the Imac wont start op whit the k4100m is it broken ?
My Old 6970 1gb start op just fine, and Work
you need to flash the card first before it'll work
@@JN396 yes. But to flash it. I have to start the imac,
@@Theoneandonlybaconator ok....so what's stopping you from flashing the card? Have you tried putting the rom onto an external flash drive, disconnecting any ssd / hdd to the iMac, and remote terminal /ssh to flash? docs.google.com/document/d/14L_Rj7gLXOeMjUyylG-Sftqx-pApBc-EW2CMUOuhoug/edit
@@JN396 hmm no i hav not, that maybe be my problem 😓 thanks
@@Theoneandonlybaconator no worries, take your time and you'll do just fine! Curtis also shows you how to reflash bios at the 11:20 marker in this video: czcams.com/video/0b_YzIjOvOE/video.html&ab_channel=CurtisGross
Hello which is better the GTX 780m or the K4100m
Cristhian Paladinez the 780m is faster, but no custom vbios for brightness controls yet.
Thanks Curtis, I think I'll decide on the 780m
We have released a VBIOS with native boot screens and Backlight control (kext mod needed) for the 780M. The 780M is slightly faster than the k4100M. But on day to day use I cannot tell the difference.
does this enable target display mode?
Target Display mode only works if the iMac can see its own Display as internal, So any card that is Backlight enabled at the time of boot. however High Sierra is a the last OS that TDM works properly in. On Mojave/Catalina you will have a black screen when leaving TDM. The iMac must be put to sleep using the keyboard combination, then woken up to have a working display again.
just upgraded to k2100m that`s a pity
Nah - that’s a great card! I’m loving the k610m and it is way slower.
@@messing-with-computers does it mean that technically we can put any card on it and just loosing the brighness and bootload?
@@messing-with-computers stupid question: is the boot screen mentioned here the one that allows to input some commands ? because my account automatically changed from admin to standard and in order to reset i need to digit some commands when restarting the mac. does it mean that if i dont flash the gpu first i will not be able to do that?
Not sure if anyone can help, but I've followed the steps on this tutorial, and success!..... at first. After using it a while I launched a game, and it crashed to a gray screen. When I reboot it chimes, between 3 and 5 weird chimes. Unable to use any startup commands as far as I can tell. When I open the case, I see all 4 LEDs are lit. I don't even know what to try next? Any suggestions?
Thanks!
I’m curious, were you able to get it running again?
@@nelsondog100 Unfortunately, I wasn't. I gave up on it. I'd taken the thing apart about somewhere in the neighborhood of 20 times. I took it in to get recycled, and felt really good about washing my hands of it at that point lol.
@@slingbladez1360 well that’s kind of discouraging for me but, at least you tried your best🙂
