SajinCpu imc degration would be my guess.
SajinNo problem. No way to really check unless you don’t mind using massive amounts of voltage (which could also cause more degration issues) to see if you can get it going again because the imc may need massive amounts of voltage to make it work properly now. 1.3v vsa/vccio is the most voltage you should use.
INTELNote Altering the frequency and/or voltage outside of Intel specifications may void the processor warranty. Examples: Overclocking and enabling Intel® XMP, which is a type of memory overclocking, and using it beyond the given specifications may void the processor warranty. If an overclocked processor was enrolled in the Performance Tuning Protection Plan (PTPP), the protection plan will cover processor replacement only, not memory replacement
RainStrykeThe i9 9900KS has more power headroom than any other CPU for that socket. Also, in my experience, the 3 9900KS I tested were way more capable of powering the 4000MHz+ RAM than any other chip I had. The two i9 9900K's I attempted to run my 4266MHz CL17 RAM on, didn't even boot... I even tried pushing the voltage to 1.55v and blast a fan directly onto the RAM, had more luck with a i7 8086K...I would suggest disconnecting any other hard drives except for the drive running the OS. I've had HDD's cause boot failures in the past and allow a successful boot intermittently but it could be a failing drive. I would consider checking the PSU, you moved from a RTX 2080Ti over to a GTX 1060 which takes considerably less power to run, you can monitor that with software like PC Wizard to see how your voltages look when you stress your hardware. I've had a similar problem like that on my i9 9900KS when I had it... it even happens on my i9 10900K. Sometimes a windows update will mess with my overclock and I have to figure out the new voltage requirements. I would suggest setting the XMP profile and after the profile is enabled, manually set the voltage up .5 from what the XMP profile uses (Example: XMP uses 1.35v so set to 1.4v.) That is what fixed my problems. Also, be aware... that's voltage range where you need to watch your temps, make sure those RAM sticks are getting some decent air flow. **SIDE NOTE**I sold my i9 9900KS cause it was worth way more than what I paid for it. I would consider that as an option to move over to Z490. I posted mine on eBay for $775 and it sold in less than 2 hours.
ZeddivileI agree with the previous responses. I would just add that you should RMA the 9900ks. I recently experienced the same issue of loosing a memory channel on the IMC of a 9900KS. Intel asked me to take an image of the QR code on the CPU and within two days of receiving the CPU approved and sent me a check for more than the MSRP... Just as expected. Intel and AMD respect their warranty's and their customers....
RainStrykeI don't think the RAM voltage is linked to those unless there is something else going on with the XMP profile, i'm 99% sure it's not. If it's something with the CPU, you must get it sorted quickly, cause that warranty only lasts 1 year on the 9900KS. That's another reason I sold it and went with the 10900K where I have the standard 3 year warranty. XMP is very finicky. It's not promised and marketing on it at this point is misleading. I've had my fair share of working with high frequency RAM. My Gigabyte Z390 Master does great with my 4x8GB 4266MHz CL17 kit as long as it's paired with a i7 9700K, the i7 8086K I had would boot with it, but I would get a bunch of soft crashes in the OS. The i9 9900KS was a little better, but still had some random crashes... Even my i9 10900K doesn't really work with that kit. So I decided to move down to a 4000MHz CL18 kit. Also, they don't always promise the full kit works, sometimes it can be just 1 DIMM or 2 DIMM's and not all 4 even though a kit of 4 can show up on the list. MSI does a good job of telling you what configuration works, my Z390 ACE also has strong memory support. Do you have the latest BIOS for your motherboard?Have you checked the Power Supply? Also, make sure you are not using modular cables from a previous power supply.
RainStrykeI decided to return my i7 8700K I had because I didn't have any real plans for it... Luckily Newegg took it back because it was unopened. I now have an extra MSI MEG Z390 ACE laying around. Hit me up in PM's if you need a new board, I know it's in good condition, i'm not really trying to sell it right now but I would rather see it in good use and I can get you a pretty good deal on it.
HE4THENThanks. That was with a brand new 9100F out of the box at standard settings and standard RAM timings. Could it be the motherboard? I checked RAM slots for damage and also motherboard CPU socket pins for damage. Nothing. Both are ok. Also no thermal paste o. It and always using non-conductive thermal paste.
Nealx01do you have any other kits of ddr4? the z390dark isnt exactly optimized for micron rev E which is what that ballistix max 4000kit is. i have it also, but i also have a small mountain of Bdie. that kit isnt on the QVL and its not exactly a secret that the dark does best with samsung Bdie memory ICs. so the fact that it does fine at jedec (stock) and then hangs or crashes at XMP sounds isnt out of the question.its also possible the memory controller might just need more voltage. set Vccio and VCCSA to 1.300v each and see if the crashes still happen.report back
SajinSo it booted with two sticks without xmp, but were you able to use the computer at those settings very long before switching to xmp?
RainStrykeOkay... Did some research - I thought you were having an issue with the second channel on your board. Also, the 9100F has a lesser IMC, rated at 2400MHz. Some memory types just don't work well with those boards, it also looks like EVGA does not really support Crucial XMP RAM at all when looking at the QVL list.https://www.evga.com/support/motherboard/I was curious if my boards QVL to see if it could support your RAM. They have 64 entries for Crucial, they support like 1000+ XMP configurations where EVGA has a basic list. Looks like most of their support is geared towards G.Skill then Corsair with a few Kingstons, but that's about it after the 4 Crucial kits they support. You could return the CPU for store credit and move to a G.Skill kit... this one is on the QVL list:https://www.newegg.com/g-skill-32gb-288-pin-ddr4-sdram/p/N82E16820232575 This is the fastest kit they support on your board:https://www.newegg.com/g-skill-16gb-288-pin-ddr4-sdram/p/N82E16820232759 There is a guy on these forums that had some really good luck with Patriot Viper RAM. ***PLEASE NOTE THIS IS LUCK OF THE DRAW*** Not everyone's Z390 Dark is going to work with this.https://forums.evga.com/Patriot-viper-steel-ddr-4400-MHz-is-cheap-17000-ish-m2964431.aspxI actually purchased it right away when I found out about it, thinking it would work with my Gigabyte Z390 Master. I couldn't get 1 stick to boot with XMP enabled, and that kit has a secondary profile that runs it at 4133MHz too. Didn't work out, so I had to pay.... too much to get the kit I wanted. Here's the Patriot RAM:https://www.newegg.com/patriot-16gb-288-pin-ddr4-sdram/p/N82E16820225144 Who knows... if you feel like putting in the effort, someone at EVGA might be able to help you get it to work. But it might be a problem if your memory is Dual sided... Most of EVGA's support is geared towards Samsung single sided kits under the G.Skill name.
