Question Can someone help me with under volting my 13700k?

[Deafmute420]

Ok I've been having a lot of trouble getting my CPU tuned. I have a 13700k on a gigabyte z790 aorus elite ax ddr4 with thermal grizzly aeronaught and a corsair capellix H115i AIO. I have done a lot of research on the values I should be achieving. I keep undervolting it and no temperature drops. I've gone all the down to -0.172 offset and it's still hitting 100 C during benchmarking. I really want to figure this out before I have to take everything apart to see if the mate of my cooling block to my chip isn't right. I really don't think it's my cooling system because when I stop the benchmark my temps almost instantly drop to 40 C or less. Problems I've been running into are: I had to figure out that I need to turn my AC off because when it kicks on my PC will crash during benchmark. Other things I've considered is if you research my AIO it doesn't actually come with standoffs specifically for LGA1700 so what exactly is the measurement for stand off height for my setup (I have caliper)? Another thing is I can not find the bios setup manual from gigabyte for my mobo because they use confusing terms, like what exactly do the perfdrive profiles do? I have it on spec enhance instead of optimization because they claim it runs cooler but I find people saying the contrary. My configuration is perfdrive spec enhance, undervolt protection disabled, core multipliers are 2 good cores at 54x and other 6 are 53x and E cores are 42x, power limit 253, offset is currently -0.160, load line at high. I really would appreciate some help.

Edit: to people commenting on stand offs I have researched this already at the time of the build and from what I found the stand off sizes are the same. If you know specific details of this exact model and know of an actual difference in this hardware I would like to know.

You have to use the correct standoffs.

Bro after scouring the internet I found something specifically talking about it.

I think you were right about this and I'm sorry I was so short with you about this. If you watch the video and see how small of a difference in size they are, I didn't think it would be a problem. I think I am wrong and will do some hardware mods before I continue on my OC. Thank you for trying to help.

A contact frame can help.

Yes, I've been looking into those. Do you think the der8auer thermal grizzly one is better? The tolerances are supposed to be better but I see a lot of people complaining about too much/too little pressure and having memory controller problems. I don't see as many problems with the thermalright one. Also der8auer claims theirs are compatible with a .2 mill IHS lap. I have a caliper and micrometer but I'll have to look at my torque wrenches. I'm not sure if I have one that can do 0.03-0.06 Nm. So idk, you think thermal right or Der8auer? (My ancestors are german and I've always trusted Der8auer)

Have you tried Light Load Calibration? It's the easiest way to undervolt. By default it's set to 9, start decreasing it, try 7 for start and check stability. If it's stable, try 6 and so on.

Don't expect much, 13th gen don't have much room for undervolt unless you drop the frequencies a bit.

I'm getting 28k CBR23 @ 180 watts with a 12900k, so yours should be getting a bit higher score at 180 watts

yeah it's mainly that gigabyte has different names for everything so its kinda confusing. Also im 95% sure its something physical with my cold plate height. So I'm going to get new standoffs and a contact plate before I go any further. If you are more specific with load line calibration it would actually make more sense to me than this gigabyte stuff. like what mOhm you talking about? idk what 9 means because gigabytes nomenclature is like normal, high, low. turbo, extreme, ect.
