Upgrading an NP9870/P870DM-G to an i7-7700k

Hello all. I recently acquired a used NP9870 for a good deal that I plan on upgrading. I'm currently looking at the possibility of upgrading to a 7700K from the 6700K. I have read that it is possible to do and someone was working on the software necessary to do so. Did anything ever come of this? I cannot seem to find the thread where it was talked about. I would really like to upgrade my CPU as I plan on doing a lot of autocad work in the future and I really just like tinkering with things and have yet to try my hand at software. Any help will greatly appreciated. Thank you

 

Ok, it was this thread: http://forum.notebookreview.com/thr...-6700k-with-a-7700k-on-the-p870-model.800000/

 

All you need is a BIOS to recognise the 7th gen CPU.

The question is, why bother, you can undervolt and set the 6700K to the same multis as the 7700K. Other than the revised 14nm process making the 7th gen a tad more efficient and overclockable, they are basically identical

If you really want more CPU powah, look at adding cores by upgrading to 8th gen or 9th gen CPUs. My 9900K upgrade literally doubled the maximum output of the 6700K it replaced.

 

I was looking to get efficient power. Enough juice to get the job done but not so much that it drains battery down quickly. How would an 8th or 9th gen work? I thought only the kaby lake cores would work on these machines.

 

How would I go about getting a custom bios to support a 7700k? Would Prema be willing to sell one?

 

No matter what chip you get the battery wont improve. 8th and 9th gen would drain more power.

 

So the 7700K would be the most powerful CPU I could install without seeing a major drain on the battery, correct?

 

All of them including the 7700k can put a major drain on the battery. This device is not designed to last long on battery under load (330w power brick, 95Wh battery) it's just a limit or battery tech.

 

So I have found a couple of benchmarks of people who have installed a 7700K in a p870dm.
Here: http://valid.x86.fr/qnklp9
Also here: https://browser.geekbench.com/geekbench3/8500151

I now know it is totally possible to do. I just have to try and get the prema mod bios. I do not think I will be able to do this. Prema does not sell his bios to individual users, correct? Only retailers can get it I have read.

@Papusan How did you come by obtaining the bios?

 

It's totally possible, I ran it but you are going from a max 4.4ghz ish to 4.7ghz ish with a similar power consumption increase.

 

indeed. i started with the 4790K at 4.2 Ghz everyday, 4.5 Ghz benching and 4.8 Ghz balls to the wall (P751ZM)
followed by a 6700K with 4.5 Ghz everyday, 4.8 Ghz benching and 5.0 Ghz balls to the wall (P751DM)
followed by a 7700K with 4.8 Ghz everyday, 5.1 Ghz benching and 5.4 Ghz balls to the wall (P751DM)
now upgraded to a 9900K with... clocks still to be determined haha. but so far 5.2 Ghz seems to be balls to the wall (P751DM)

 

So there is no possible way to get 5.0 Ghz out of a 7700K, even if it won the silicon lottery? How did you run it?

 

The best ones were used for the 8086k generally so chances are generally not good.

 

sure it is, look at the post right above yours

Thats good to know. Jaybee83, how did you come by getting the prema mod for your system?

 

If the prema bios is unavailable to me what other options do I have for this project? Any at all or should I just sell my processor and move on?

That upgrade looks like it will only work with coffee lake chips. I was looking more for a different bios that will support the 7700K I already have.

 

not sure, but iirc its compatible with skylake, kaby lake and coffee lake chips. but best to check the thread and ask the users there.

Thank you @jaybee83 Looks like I have some reading to do. I wish these long threads had a search option.

 

You can search in the thread you are watching

Hi
Sorry for my english im french,
I want flash my p775dm3 but this bios work on kaby lake 7700k because i dont have money actualy To buy 8086k.
Tanks.
Yes it will, bios supports all cpu's from skylake to coffee lake.

Hey,this mod work with my laptop too???Thnx

Yes it does, download the attachment and you will find the modded bios for the clevo p870km and km1.

Follow the instructions and flash that bios.

hi.. awesome works.. so where can i get bios P750DM-G works for coffelake? kudoss
Download the attachment and click on the readme, it tells you that all p7xxdm bios are the same no matter what. Find that bios file and flash it to your laptop. Flash the "P7xxDM_9.bin" if you have a 9th series nvidia gpu OR flash "P7xxDM_10.bin" if you have 10th series nvidia gpu.

Do not flash any other bios not meant for your laptop though!

Good luck

This gives me some hope

 

So I have purchased a sky pro programmer and the pomona clip. Now I play the waiting game so I can get to upgrading. I'm so tempted to just try to flash the bios without it but I need this computer for school lol.

 

I tried updating the bios but my laptop is stuck at a black screen. I have no idea how to do the pin mod as mentioned in the coffee lake upgrade thread. Im stuck.

 

Ok can you go over the exact steps you have done so far? What BIOS did you flash?

 

I have done steps 1-8 listed in this thread where I got the bios: http://forum.notebookreview.com/thr...kylake-kabylake-clevo-lga1151-laptops.821694/
I haven't done step 9, pin mod, just because I cannot figure out how to do it. I do have a backup of the bios, I've just kinda given up at this point. I'm waiting on some thermal compound to arrive before I put everything back together as I just had liquid metal on hand and that doesnt work at all I found out. Today has been a day of learning, that's for sure.

 

So I just learned the 7700k does not require the pin mod. I believe now that my system is just bricked. Im trying to locate the bios chip to reprogram it

 

Which file did you flash?

 

The one that said p870dm.bin

 

Have you reflashed it?

 

Attempting to dismantle it now

So far I have removed a lot of screws and broken the casing on a fan. Everything is loose but wont come apart.

hey @Meaker@Sager there isn't a chance I could send this to Sager and have them do the mod for me is there? I feel way in over my head.

Okay, I have successfully dismantled the laptop to get to the bios chip. Now I just have to figure out this programmer

It seems the laptop I'm using cannot recognize the skypro. Any tips?

 

This was the bit to figure out before the flashing.... check the USB cable is ok, is it powering up? Did you install the drivers? What is showing in device manager?

 

The device shows in device manager with a little yellow sign and an exclamation mark. I believe it does not have the right drivers. I looked on coright's site and could not find the driver.

 

I have the correct driver now

 

I'd advise flashing the backup you took of your bios.

 

Anyone know which chip type, manufacturer, and model name to select on the programmer?

 

The one it says on the chip.

 

again: straight, simple and to the point, love it

The chip didn't have any manufacturer information on it. Anyway, with some help from @Prema my system is restored and working once again.

Prema to the rescue!

?

 

He really is a good guy. Walked me through everything and answered every question I had. Even hooked me up with a 7700K upgrade. Only problem is the screen won't work on boot. Laptop starts, LEDs light up, windows music plays, just the darn screen won't cooperate...

 

Does an external panel work?

 

I just hooked it up to my tv with no luck after verifying the 6700k works on the same tv at boot. Problem is in the video card?

 

The problem is the bios initialising the card.

 

Crud. There's nothing I can do to fix that, is there?

 

It's a tricky one, I assume with the previous setup you never had boot issues?

 

No issues ever. Starts up fast every time.
