Official Coffee Lake Refresh Thread/BIOS for ALL Clevo Laptops - RTX CARDS NOW SUPPORTED

Thank you I can update when I have now I7 7700K ?

 

If you use the DM version you can, as it is backward compatible. GL

 

Ok i succesfull update this bios Thank You very much ! So now I can put I7 8700K but whose pins i must isolate etc . Know I7 9xxx i must isloate this pins and I7 8700K others ?

 

you have a picture in the archive with the pins to isolate

 

What procesor will be the best to P775Dm3 ? i7 8700 vs 9700 or 9900K but i see the temps maybe kill the vram.

 

The 8700k is a good option, with delid 4,4-4,6Ghz with some undervolt, it could give acceptable temps. Or imi 8700nonK. For gaming 8600k is also a good option.

 

30% games 70% rendering etc.but I see 9700K litte cooler and better about 10 % ?

 

I did not have 9700k so far

 

Upload the archive here I will download it and place it on Yandex disk. https://dropmefiles.com/

 

Guys i wanna order a TL866II Plus but dunno which reliable source store to get a kit from!?

https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20200505170833&SearchText=TL866II+Plus

Or Amazon?

https://www.amazon.de/s?k=tl866ii+plus&__mk_de_DE=ÅMÅŽÕÑ&ref=nb_sb_noss_2

Or Bangood?

https://www.banggood.com/search/tl866ii-plus.html?from=nav

Which one do you guys recommend? And a good tutorial for it? Thanks in advance

 

If only used for bios flashing, another option is to flash via raspberry pi:
https://www.rototron.info/recover-bricked-bios-using-flashrom-on-a-raspberry-pi/

Then you can use the pi for some other purpose down the line.

 

I need the TL866II because i won't be dessoldering the BIOS chip. it will be flashed in the board and i wanted the spi programmer to maybe flash the GPU as well in the future (still dunno about this one) but my main purpose would be to get a SPI programmer to be future proof

 

Fair enough, I should note that I just used my Pi with flashrom to flash the dsanke bios onto the p870dm board without de-soldering the bios chip (I use the SOP8 clip).

Also just did the same with the clevo 1070 (though had to update to flashrom V1.2), again with the vbios chip still on the card.

I may get a TL866II myself though, for use with the EEPROM on the ECU of my motorbike.

 

Awesome! I might consider getting a pi after I get the spi programmer as a complement

Appreciate your help buddy. Thanks

 

Guys,
I have updated finally my 751dm2 with dsanke bios. It was very difficult as it started with black screen. We tried both rtx and dm versions but black screen. The cpu was 8600k, the pins were covered with kapton tape. We have also tried with two different gpus, 1080 and 1060, both with the gop modified vbios. Still nothing black screen After my friend (ex dell engineer) with debugger modified some cpu id lines in the bios, and after that it worked perfectly.
So at the moment everything seems to be ok, however it is the DMx version, not the RTX version, and I am planning to buy a clevo rtx card (most probably 2070).
Do you have any idea what could be the issue? I am afraid that we cannot fix with the rtx version bios hance the whole purchase would be useless. For the summer I planned to make a mobile gaming laptop as I travell pretty much every week.
Someone told me the EC could be also an issue, if it is old, however I do not know how it is connected with bios.
Any help would be highly appreciated. Fun fact, that I have "modded" 3 775dm3 to be compatible with 8/9gen intel cpu, and the only issue I had, that I need a programmer. So there was no fuss at all....
THANKS A LOT In advance!

 

Hmmm after update the bios my FPS drops about 10% why ? New drivers. Old unistall, Its posible ?

 

Could be security mitigation.

 

Can you explain more ? Where I must search this ?

 

Intel spectre and meltdown, been pretty big news.

 

Any person are interest to asio driver for clevo (audiophile usage) ?

 

I am!

 

If ou want try :

1. Install this : https://drive.google.com/drive/folders/1suSElUv6QFwu4GJh1jGf5mlVGL8T2KfL?usp=sharing
2. Go to C:\Windows\SysWOW64\RTCOM
3. Check this elements is here : realtekasio.cat; RealtekASIO.inf; RTHDASIO.dll; RTHDASIO64.dll
4. IF this element is not here no panic.... copy and paste from the dowloaded files

WARNING !!!!​

• If you use creative suite (sound blaster connect) you can't set 24bits 192Khz! You can set 24bits 96Khz max
• This driver works only in 32 bits mode so you can't use audirvana... but foobar 2000 works perfectly (and i listen upgrade with the asio driver in my focal elegia FRENCH guy FRENCH headphones)
• If you don't use foobar or a player but you want use you headphone in maximum quality set in default audio source the numeric realtek audio because if not, you don't use really you dac sabre ess 9018KM2

ENJOY AUDIOPHILE COMUNAUTY ​

 

In my P775DM3G i use Creative Blaster Connect and Realtek 6.0.1.8279 and work good.

 

where can I off this security mitigation. ? On orginal clevo bios FPS go up on prema go down 10%

 

Likely need to mod your bios with UBU to downgrade microcode to some revision prior to 0x84 for coffeelake (I like UBU version 1.69).
You also need MMTool, which can be found here:
https://forums.tweaktown.com/gigaby...system-info-benchmarking-stability-tools.html

For your current CPU, if you have a backup of your previous bios prior to the 10% performance loss, you can extract the relevant microcode from that and add to your current bios.
The dsanke bios appears to have revision B4 for the 7700K (CPUID 906E9), you want something older than 0x84 for Kabylake as well.
https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf

All quite risky work, have a bios programmer on hand for recovery.

Note, you may need to remove or rename mcupdate_GenuineIntel from System32.

But now i have modded bios by dsnake on this bios I lost performance about 10%. On oryginal bios performance go up 10%. Ok now I have I7 7700K

 

I've just updated my post with more detail, basically you need to downgrade the microcode in the dsanke bios, maybe @dsanke can help you with this.

I don't have a P775DM3 for testing, otherwise I'd offer to do it.
In the past I've had to recover via a raspberry pi and SOP8 clip due to oversight while removing microcode myself.

 

@dsnake Can you help me ?

 

Also, sorry to post so often, but you may have luck disabling the protection (for performance) for now using this software tool:
https://www.grc.com/inspectre.htm

 

Nothing change. Maybe this bios better work with intel 8th and 9th gen procesor ?

 

Unsure, I am keen to test the dsanke bios with an older microcode for coffeelake and see if there is any performance improvement (when I decide which 8th gen or 9th gen CPU to buy).

Would be quite interested to know.

 

In few days I will buy I7 8700K now I stay on I7 7700K.

But I don't know why performance drops...

Maybe @dsnake make new bios on
1.06.11 base ?

But on this bios 1.05.11 dsnake I normal run I7 8700K 6/12T?

OK i know where is my performance GPU work with x4 3.0 PCI-E... Why? Reinstall new drivers etc. on bios max settings now is lock on x4...


And I can,t downgrade to orginal Bios 1.06.11 ...

 

I would run a PCI-Express bandwidth test to confirm that.

 

If you can ? I search a lot of options I can max change to x4. in Warzone FPS drops down about 15-20FPS

 

Maybe this bios support only Intel 9th generation to work perfekt with full power.

 

Nów I install oryginal Clevo bios again speed is x4. I remove the card clean the pins on gpu and mother board, this same problem. Gpu broken ? But she is stable, cpu too, ram too

 

Hoping I'm not asking a question that's already been answered, but why is the @dsanke 1070 GOP updated vbios only 253KB, when the stock vBios on my clevo 1070 is 1024KB?

I was going to flash the GOP updated version via flashrom but obviously there is an error due to the size difference.

The vbios version on the card at the moment appears newer anyway, so may be ok.

GOP updated vbios version: 86.04.2A.00.26
Current vbios on the 1070: 86.04.2A.00.27

 

When I flash dsake bios automaticly flash kbc and EC ?

 

For EC use the one from Clevo and don't mess with it. Bricking a EC might end you with a hardbrick and having to buy a motherboard if that happens. Just flash the EC for your P775DM3-G from Palkeo mirror which is the version: 1.06.01. And stop messing with the EC. The bios chip is recoverable with a spi programmer. The EC is another story

 

It's most likely that either you have bent pins in the mxm socket, or in the cpu socket, remove your cpu, give the cpu contacts a good cleaning with some alcohol, check that all pins are not damage both in the cpu socket and in the mxm slot and test again.

 

All pins are good. I will

maybe i will brick EC but i will program EC 1 and 2 with programmers Nothing happend

 

Don't go flashing thing willy nilly, check all the hardware first.
Can you can some well focused photos of your gpu, cpu, mxm socket showing the pins and cpu socket?

 

Yep No problem. But if i remove ram cpu gpu and try power on the reasult is the same. My problem was start when I try reflash Dsake bios to oryginał bios but I was put the battery and the flash was complete I put power button to off and laptop and dont start .

Now I reprogram the bios on programator to oryginal Clevo bios Nothing happend reprogram EC to oryginal Nothing happend. Vbios to oryginał 1080 to p775dm3g Nothing happend.

 

EC needs to be desoldered with a very precise de solder iron and possibly a microscope and you need a new EC chip programmed from factory. The EC chip can't be programmed on-board like a spi programmer..

Don't stay stuff that isn't true.

 

Where can buy a EC new Chip with from factory ?

 

Ebay. Good luck trying to solder it at home

 

I have found !
So you have in you laptop 2 ec bios... but i have the référence... ITE 8587A
I you want a buy this chip : look this https://www.ebay.com/itm/153217410177
The programer https://www.ebay.com/itm/ITE-ENE-IO...EDID-VER-2-6-without-EDID-cable-/172747611949

 

Sorry, but I'm a bit lost, you first said that your laptop GPU was stuck in PCIe x4 mode, now you say that it doesn't boot.
Is the laptop in fact working, or did you start messing with firmware and bricked your laptop?

Even if you buy those EC chips you need a ZIF socket so you can program them before soldering them into the motherboard.

If you have an hot air station and some experience soldering SMD's its not that hard, its just a TQFP package, but if you never done SMD soldering you will end up with a lot of ripped traces.
The ZIF socket is something like this:
https://www.aliexpress.com/i/1762279813.html?spm=a2g03.12057483.1000001.8.2baa654f2aL6iP

But you need to check pin count, and you need to also source a programmer than can program those chips, not sure if a cheap-ish TL866 can program them, you need to check the supported IC list.

But even at 6$ for the EC's, plus 60$ for the programmer, plus 15-20$ for the ZIF adapter, plus all the required soldering equipment you will exceed the value of a new/used motherboard, and you still don't know if it will work.

Did you first do a dump of your BIOS before you started programming random files into your BIOS flash chip?

EDIT: The programmer you linked does the EC programming over the keyboard connector, because there is a JTAG interface in there, but that only gets you one EC programmed, because only one of them will be connected to the keyboard.
Thats 90$ for the programmer and you still need a FPC ribbon of the correct pin count and pitch, its just another 10$ into the mix.

Explain what you did first so maybe we can track back to where all went wrong, might still be possible to fix it by just flashing the correct BIOS..

 

On this chip i put EC 1 or ec2 ?

 

now i have this problem after reflash the bios from dsake to Oryginal 1.06.11 i film now how the laptop cant run
