The usual disclaimers will apply.

 

How's 6 core with HT (12 thread) compatibility going on these bioses?

 

what is your device I have to know cuz different device have different bios

 

P870DM3

I remember a list from March? April? where all CPUs were working on almost all the LGA1151 Clevos except the 12 threads

 

IS P870DM3 SAME AS P870DM2??

 

Yes, same everything except GPUs and heatsink

 

SO YOU CAN JUST FLASH P870DM2 BIOS ON IT IF YOU HAVE BUG OR SOMETHING ELSE YOU CAN ASK ME

 

Just don't ask where caps lock is

 

oh sorry

 

I flashed the BIOS to my KM1 for testing purposes, I thought it might be fixing my 4x16GB memory issues, until now everything seems good, but no G-Sync? is there is any fix for that? and I still have the same memory problem .
Thanks.

 

I will make a 870km base (support 16treading) bios for everyone if Intel didn't send killer to me

 

Then I'll ask God to save you, don't worry, just keep low profile,
You are doing a good job,
Good luck.

Flashed, G-Sync confirmed working now, and I can see the model in BIOS information KM-KM1 instead of TM1 in the old version.

Thanks for your kind efforts, I'll try to find any 8700k cpu to test it, now I'm still using the 7700K.
Can you add more unlocked options in this BIOS?
Can you customize the booting logo?

I'll do some testing and update, and if there is any special test could anyone needs me to do I'll be happy to do it.

 

I can change boot logo

 

Is there any notable bug or so? If not, then it's gucci

 

Up to now the last version working fine with me no issues. It has very limited options for OC I can OC the CPU with basics things like undervolting, but still under testing. I'll update if I found any bugs.

 

How can I flash the EC? is it included with BIOS?

 

I would recommend not touching the EC unless you have some issues like power throttling out of nowhere etc.

 

Sometimes it is, sometimes it's not. It's a separate flash in the routine.

 

No power issues, I thought maybe it will fix the memory problem.

 

It has nothing to do with that, I've already gone over the only culprits with you.

 

Sorry but this is simply your board. I know it sucks but that's how it is sadly.

 

can you tell more detail with your memory problem cuz I repair lot of laptop already I guess I can help you to fix

 

Thank you for your kindness, you can find all information here:

Thank you for your kindness, you can find all information here:
http://forum.notebookreview.com/thr...ger-boots-if-using-all-4-memory-slots.822769/
I'm using your new BIOS for the KM1.

Attached the ram brand and model.

 

Eng. Meaker can you please explain more about what you mean about "disclaimers". Thanks

 

BIOS flashing can be risky, 3rd party files can be more so. Have a method ready to recover your machine worst case and take a backup of your original.

 

Thanks sir, this is what I did exactly. I have the backup but I didn't use it, so I'm not sure if it's working. And I have a programmer for the worst case.
I hope that Sager can provide this kind of BIOS updates/Upgrades officially someday

 

Without sanction from Intel that is very unlikely.

 

Sir, I think there are many safe indirect ways and workarounds that can be done far away from $ntel sanction and agreements. And what we have here is one of them.

 

Yes but you cant officially as a company.

 

I got the i7 8086K , do I need to mod it? like the attached picture? or something else? or no need?

 

yes you can use pencil to do short use tape to do isolate

 

I didn't succeed to short the 2 pins with pencil, so I just isolate the 2 pins and left the other without shorting them.

Issue 1: No matter what you set for the CPU speed in the BIOS, it's only working @4.40 and the cash @4.10. I succeed to run CINEBENCH with reasonable score (1408) as attached, and the temp was good (84c) without any undervolting, with -60 undervolating I can see temp under 80c, all at default settings.

How can I force the CPU speed to run faster?

Is that 2 pins needs shorting is really important? how to do it with an easy way?

 

Issue 2:
In the device manager only shows 8 threads, in the task manager performance monitor shows 12 threads.

 

@Meaker@Sager @52571abc
I need some insight, at least I need to know if I stay using the CPU without shorting the 2 pins is there is any risks for the CPU or anything else?
If there is anyway I can short the 2 pins please advise. and why the speed is limited to 4.40Ghz? coz of that 2 pins or something related to the BIOS?
I still have a big jump from the i7 7700K almost 40% increased on CINEBENCH, with undervolting -100 the temps as you see are 70c max.

 

You don't need shorting 2 pins on cpu if the motherboard already recognised your 8086K cpu and boot normally.

DId you already try to overclock by intel xtu or throttleStop?

If yes and can't, the reply is missing/not converted acpi table from original bios

 

As you said, do you recommend me to try using the cpu even without the isolated 2 pins?
I didn't try OC by any tools. But inside the BIOS I set all cores to 5.0Ghz.

Issue 3: I found that the BIOS deal with the 6 cores cpu as only 4 cores as the picture shows


And this is the BIOS information:

 

Now I can get the 5Ghz using ThrottleStop as below, but the temps get the 97c.

 

The ACPI list fix required lots of Time basically 4 hour per unit
but I will try

 

With ThrottleStop @4.70Ghz I got big increase in CINEBENCH (1537) and the temps at 80c max. I'm not an expert but I'm trying to tune the cpu as much as I can.

 

Regarding to the Pins (Isolated/Shorted) do I need that or not? The isolation is easy, but I almost damaged the cpu when I tried to short the 2 pins. Please advise,

 

can u do something for me


make a video and upload it to YouTube



or u can send me your video I will edit it and upload (but I will say that is you

 

What exactly you want me to show in this video? I can capture all pictures you need, it's more easier. I can do any test you ask for and provide the results.

 

No the isolated pins on cpu should be necessary to not burn motherboard.
The shorted pin on cpu is needed only in case the motherboard do not boot with modded bios alone.

 

Good to know, then I will just keep the isolated pins, thank you for your kind support.

 

Do you recommend that I flash the old BIOS version, the one shows TM1 in the bios information? I can sacrifices the G.Sync for the CPU stability?

Delid the CPU and use liquid metal to help but it is more cores.
