I used Aceton before mounting it and used a big blob. I tried to heath it up a little before I ran it and after that I did what Leeghoofd said. I could run 6GHz CB11.5 at -170C without any issue now. Seems to be better now.

I cleaned it with Aceton, used a big blob that covers the die and set it ready for a new run. After that I will try more if needed.

Thanks for the advice. I wasn't planning to combine things. That way I can't name the cause of issues. About lapping, I lapped my first heathsink/cpu more then 10 years ago. I never made any mistakes with it.

Do tou mean the black peaces on the pcb? You bench without any of it? I will wait with lapping it for now. I do have everything I need to lap it.

Thanks for all the tips. I will try them soon. Edit: I have a bottle of Aceton "replacement" which is 2-Butoxyethanol. Is that enough?

I tried a big blob before but I never heated it up before the run. Yesterday I tried a small layer of grease but that obviosly didn't work. I cooled it down to -80 and then heated it up to -40, after that I went down.

Ok, here it is. I was looking for the best sub forum for this. I was wondering what the best way is to apply thermal grease to make sure a crack doesn't happen. I had it twice this weekend with 2 different methods. At -100C or beyond I saw positive temps. Before I say how I do it I am wondering who has a method that works most of the time (besides the new Kingpin thermal paste).

I have had enough bad luck with hardware lately. Let's not challenge it. Edit: Now I think of it, I did have one win. I placed my defective sensor (strange temp issue beyond -140C) as a backup sensor. Both sensors were fine untill -185C.

It is to late, I was thinking about doing that but... While heating it up I saw a little bit of water near the power switch. So I turned it off. I don't want to take the risk.

It was a sata issue. I moved sata to a different port, after that it worked. But now I have to stop anyway because now the tim did crack... +18C in XTU.

At -50 auto and vccio 1.1, vccsa 1.2, at -100 see page 1.

With voltage settings on page 1 or any other voltage I can't boot to Windows with -100C where I could with -50C. I am still looking, but does anyone have an idea? Blue screens all over the place. Edit: -50 was with stock voltages

Thanks I didn't try to get them down. I will do that later. I am not that well known with rtl's so I want to look at it when I have time. This was a quick run.

I renewed my submission since spu speed was faulty (and I wasn't able to edit it): Sparks.nl`s SuperPi - 32M score: 5min 54sec 281ms with a Core i7 6700K

Mine are from mid 2017, I had no 4266 option. I bought 3600 C15. 4133 was out the would have been about the same from what I expected. Edit: If money was not an issue I would think of buying 4266 now.

I bought the highest bin of G.Skill.

My first more serious pi 32M test. First run in XP. Waza proof at 5m 55.537s. Still my g.skills, the hofs are still waiting for action. I now officially have 2 4133 kits. Nice

The second kit needed a little less voltage to get it to post, so the 3rd try gave a post. Their first boot gave this: The CPU is cooled by my Single Stage. Edit: I did a quick test on 4266MHz. C12 didn't run yet but 4266MHz C13 did... I really am beginning to like the 2nd kit...

I've got these kits since last summer and never got them running because of some bad luck. First I will tune it, then I will run my 6700k.

I got a series of bad luck last year and this year my Cascade died on me. I think I will hold on to them for a little longer. I will bin them first. Maarten

I finally got these running! this is the first try below zero with this kit on my mOCF and they are doing well. The beauty is that I have a matching kit, the 2nd kit has the 2 next serials and seems to operated simular until 4GHz C12 on air. I will test it soon bu I expect it to run fine. Now I have to tighten the timings and test some more voltages. After this I still have the HOF's.

At what voltage did the cpu score it's result for cpuz and pifast? (980x)

Thanks, I will flash it on my 2nd bios and use this. I tested P7.40 today and had no problems booting 4133 c12 on water with 6 different dimms. It was PI4M stable (didn't have more time) with 4 different dimms.

I see that bios version P7.40 can be downloaded on the Asrock website. Did anyone try it yet?

Nice, mine didn't like that on the big board. But I will try since it is driving my daily 6700k (golden on air, one of the worst on cold). Edit: my bad about the 6700k. Seems good on ln2 as well. Never fully tested tho... It ran 6.6GHz in a quick test. Oops Edit: E die picture results were gone.
