Something weird just happened with my Apex IX coffee lake mod. Started getting audio buzzing at the end of every sound effect that came through
the speak. Didn't matter if it was the monitor speaker or standard speaker, or onboard sound or video card sound. Things got a lot worse after
I did a cmos reset in that now my nvme SN750 WD Black hard drive is completely missing and can't even boot windows. Completely MIA.
Not even show in bios!

So I wonder could my motherboard be cooked? I mean its not the result of running a coffelake mod?

Thanks

I dont think so.its just a microcode after all
But running a cpu on unsupported platform may stress the board in the long run.depends on specs here,if it can handle the frequencies.(somewhat higher)
in Modules on the other hand,maybe (again same principal) changes are so small usually, like in ME updates from 33 to 55mhz

i sure hope so aswell

Well its been fun but after two years retired my coffee lake mod. Replaced the motherboard with a Z590 i7 10700K and was able to boot up the old Windows install with no buzzing sounds and smooth animation. So can only assume that something was arcing. Tomorrow going to examine the old 9700k and motherboard socket for signs of damage. After that got to get the cpu properly tested if thats possible. Maybe I could send it to Intel for testing because I'm hoping at least one of the items is still in working order for putting on sale.

Thanks

And how old was the system? Two years..kinda short period,even common overclocked systems outlive that
Can you do a one last run,let the system go idle,no background apps,unplug all peripherals except monitor ofcourse and watch the heat,spikes etc with an app of your choosing (hwmonitor,aida etc)
Signs were buzzing,noises but maybe there were also more (pre-signs) you have not noticed or did not pay attension.just out of curiosity and might light someone’s way up
Also add close up pictures from board,then clean it up with ipa or electronic spray and see you can salvage it like you said

Yeah it was a two year run. Had all cores fixed at 4600 mhz 1.285 volts. Coretemps while priming never past 74 75 degrees max. Actually a year ago had a similar issue although much more mild where the system felt jerky but it went away after a bios reset. Wish I could have done one last run but the bios couldnt find the nvme drive anymore. So couldnt boot into windows. The same hard drive successfuly booted on the new motherboard. Considering the buzzing farting sound the system was making wanted to make sure my gpu was solid before its warranty expires in two weeks from now but it seems smooth. Heaven benchmark now runs smoothly. Anyhow all I need is a spare gpu and ram module and will be able to test the old board further on the workbench but only to make sure it all works so I can sell it off. Have a completely unlocked descriptor bios ready to cut loose if its still working order. Thanks.

@davidm71 Problems with drives and with sound? This may suggest dying PCH(hope not). Since you remembered the CPU temperature, maybe you also remembered what the PCH operating temperatures were before the problems started?

Dont remember or rather never noted the pch temps. Cpu temps were always pretty good. Never passed 75 degrees under prime95. Interesting that this all got worse during stability testing in that the increased temps must have been responsible where as prior not put under those conditions. If the motherboard has died no big deal. Only paid 60 dollars for it after rebates. Also should note it was an Apex IX so would have thought the vrms could have handled it. Just hope the cpu is still good. Thanks.

I wouldn't worry too much about the CPU. As is well known, CPUs are one of the less frequently failing components. Yours was working at a pretty good temperature, so I guess the probability it got damaged is low. Especially since the symptoms you mentioned do not indicate CPU.
However, I asked about the PCH temperature also because I have 9900k(HT off) on Maximus IX Extreme and the PCH temperature is 50-54 degrees Celsius. I know that temperature is not to high but I think it should be about 10 degrees lower and I wonder if this temperature has nothing to do with the modded BIOS?

Since a week, I run a QQLS (i9-9980HK ES) on my Z170 Pro Gaming.
I use a 2003 BIOS modded with CoffeeTime 0.92:



I have used Conductonaut paste on the die, and the cooler is a Scythe Mugen 4.
I had to add a fan to cool the VRM, as they were getting very hot (more than 100°C) on torture tests.
Currently, the CPU is running at 4.8 Ghz on all cores, with 1.33 Vcore.
With BIOS 2003, the RAM sets automatically at 2400 Mhz.
The BIOS won't POST with the memory set higher than 2600 Mhz (I have 2x16 GB of DDR4 3200 with Micron chips).
With BIOS 3805, the RAM sets automatically at 2666 Mhz, so it has better RAM compatibility, but sadly it can't run with HT on.

If svarmod is reading: please, can you make a custom 3805 BIOS with HT enabled for Z-170 Pro Gaming ?




CPU-Z at 5 Ghz:





Some benches and tests at 4.8 Ghz:








Temps and power. About 160W on Cinebench.






Here is some photos of the setup:

Removing the old CPU (6700k) and the original CPU support that won't be used anymore:



Putting the new BIOS chip in its socket:



Mounting the new CPU & the cooling support, and applying the Conductonaut on the CPU die:



Cleaning and mounting of the Scythe Mugen 4. I have replaced the original fan with an Arctic P12, much more silent. I'va also added a P14 to refresh the VRM, it's mounted on top of the case.

Noticed similar ram clocking issues with the older bioses. Haven't done extensive testing, but I found that if I leave just about every ram timing on auto, it can actually clock up fine (4x 8gb oem hynix afr 2400). IIRC, the only timings I have set manually are cas/rfc/refi.

Setting rc/rp/cr wr/rrd/wtr/rto/faw/cwl et all all seem to result in a no-post. This is true even if I'm setting the exact same value as achieved via auto or worse.

Likewise, when setting any of these timings, I'd be lucky to even hit 2600.

hey everyone,
so I've been following this bios mod topic for sometime and finally decided to upgrade my 6700k to a 9900k on my M8HA but even after some reading i still have a few questions:
- I have seen it mentioned a few times that M8H does not need the insulation mod but shorting of SKTOCC pins are necessary which can be done on the MB side near the super I/O chip. does this apply to M8HA aswell?
- M8H uses a novutun NCT6793D super I/O chip does the M8HA use the same chip ( i have found a datasheet for NCT6793D which indicates pin #102 is the SKTOCC pin)
- from the info that I have gathered, on asus z170 boards to get 8c/16t working you will need a bios ver 2xxx , my board is currently running 2202 is this the optimal version?
- i have found on a Chinese forum(chiphell) a modded bios version 3801 for M8HA with 8c/16t support , is this possible? has anyone tested that version here?
- on the latest version of coffeetime (v 0.92 GUI) which of the patches do i need to apply to mod my bios i understand to add cpu support i have to add specific uCode but what do I have to choose under "patches" and "fixes", also do I have to disable ME( most of the guides use the older versions of coffeetime or AIO tool and they simply apply everything I`m not sure what to choose on v0.92 gui version and prefer to use the latest version of the tool hence why I`m asking).

sry if some questions are stupid or have obvious answer I`m trying to be as cautions as possible to not screw up.
