Is there a motherboard that is compatible with both i7 6700 and i9 9900?

This is mostly hypothetical - I am not buying or building a computer, I am just curious if both CPUs would run in a identical motherboard considering that they got the same socket and apparently have the same 'base': both are 14nm, PCIe 3, DirectX 12 and so on.

 

So would a older board that was 'top tier' for the i7 6700 run the newer i9 9900 as they got the same socket?

Different BIOS, Chipset…?

different chipset

and intel just doesnt want to support the 9900k CPU in the lower chipset, and vice versa

 

they technically share the same socket, and people have gotten 8000 series CPU running in 7000 series boards thru bios modding (which isnt available at stock)

My PCs: Desky | Beddie | Miney | Benchie

Things I need help with: (nothing at the moment)

Spoiler

none atm

I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general

Spoiler

Products I like:

Spoiler

Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite

Products I hate:

Spoiler

Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares

Companies I absolutely adore: (and hope it stays that way)

Spoiler

be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend

Companies I hate:

Spoiler

Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)

Personal Blacklisted Companies:

Spoiler

Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)

Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.

99% it's a no. 1% I'm unsure because never trust technology. Anything can be possible.

The max you can find is support for 6th and 7th gen in a board.

The 8th gen boards are unlikely to support 6th gen despite having the same LGA 1151 socket.

Had a friend's 6700k which had some board issues. Couldn't find a 200 or 100 series board (z170,z270 and all the others)

So he eventually decided to sell both and opt for a new ryzen which costed the same as the old system

Why? Duh. Intel.

Alas, it won't work, you need to make money on new boards)

Ah so that's pretty much where I was driving my point: it would work (conceivably at least) if chipset/BIOS were compatible…?

So for the sake of argument, say you could replace BIOS and chipset (or flash them, don't know which is doable - if any) you could run the i9 9900 in an i7 6700 board…

You also need to take into consideration of the power draw of literally twice the amount of cores

 

Sure, some 6000 series boards may support that, but most of them will not, and Intel doesn't want their customers to buy an incompatible board and damage something

 

This is what happens when you plug in a CPU that's super high power draw on a board that can't handle it

 

The CPU is technically supported in the socket and chipset, but the board isn't ready for it

1. You'd have to make a custom BIOS (which isn't something even remotely as easy as making a custom android rom)

2. replace the chipset? I don't know how are you going to do that and take the risk with a top tier board in case it bricks. But still that's not possible.

 

But I do like the concept of removable-swappable chipsets, but the manufactures won't do it. So let it stay a dream xD

That is some top class action. People like these are the answers for various of our questions. Salute.

My ulterior motive - and aspiration - would be run the i9 9900  CPU in the 2017 iMac 27" which according to everything I've seen online has the same hardware as the 2019 iMac 27". So yeah a lot more money than just a top tier board 😛

 

iFixit list the PSU as being the same in both 2017 and 2019 and even the specs listed on Apple shows both machines basically the same (at least the pre-T2 2019) the only noticeable difference being the GPU that goes from the Radeon 580 in the 2017 to Radeon 580X on the 2019. And of course different CPU lineup.

 

So considering Apple does have a 'policy of planned obsolescence' as well as they do make pretty much the same iMac since 2012 it would be conceivable that replacing the EFI chip (or flashing the firmware) on the 2017 model it could work with the i9 CPU.

 

Wish there were a YouTube channel brave enough to try and test this sort of whacky theories instead of the run-of-the-mill fanboys suck-up… If only Macs had RGBs to incite 'enthusiasts'…

Well, if you've got the required hardware why don't you make a video of it.

I mean you've got it researched pretty well.

A couple more days into it and you'll know if it's actually possible or not.

Depends on where you live and if there are shops out there who can help you with the smaller stuff like any chips which need to be replaced on the board or flashed seperately.

It sure will be a costly one xD but it'll be fun.

Haven't got the 2019 EFI chip. Found someone online that sells it but if it doesn't work I'll never know if the hardware can't handle or if the chip was a scam…

Oh and I am in New Zealand so pretty much on my own 😛

Or maybe not… 🤔 Had an idea, will flick some emails and see what I can get 😎
