I tested for only 2666C8-12-8 tWCL6 and is ok. My experience on this platform is still very immature. Lots to learn yet. 2000C6 pi's that haven't seen full cold yet. I hope can get at least 6-9-6 or 6-10-6 timings with full pot one day.

Hey @elmor, do you have LN2 bios for Reference RX580? I flashed with RX480 but black screen reboot hell.

Thanks. Direct Die with LM and cold water helps though.

Good to see you have similar experience on cold. People dont understand the difficulty on this platform to find good cold chips. Congrats on finding 2 amazing samples. Bump for a dedicated man.

Strong IMC, I needed cold CPU to do similar with my dimms on air.

Sold

Huuuuuge cpu. Congrats

What ambient temp is this running at?

Yeah. It’s hard when you find the limit for sure. FYI. My efficiency with 4600c14-131467 was same or little bit better than 2933C9/1467fclk. 3200C10/1600FCLK maybe a bit quicker if you test again. But knowing you, you probably tried that already lol

Killer mate. Well Done, that's where the time should be. What FCLK did you end at? Assuming 1600?

Killed it man, congrats!!!!

How do the import fees work there? Anything can be arranged.

Time to change my vote then

What zero said, or 750ti are all reasonable here in the upside down and burning land.

Price drop for one last time before I sell to someone that doesn't care for LN2 results. $750 AUD/465 EURO/ $515 USD Shipped worldwide.

So you have to mod the board to make this happen?

Awesome CPU man, congrats

How does the vpll mod work?

Bump, still open to offers.

Thanks everyone, this is one of the hardest benches around to get fast on, especially AM4 platform.

I tested every memory setting I could at 3133, 3200,3333 and 3600 in preparation for cold. My 3133-3333 memory is all the same in the end, with no benefit in timing changes Still today I put it back on ambient to test more and yet another day where efficiency went down the toilet. It almost feels that if it’s working well, you have to go cold straight after or you lose out. One reboot can make a change that you cannot get back. If AMD allowed access to RTL or IOL it would be far more beneficial for us. not really sure why I tortured myself with it again today, but I guess that’s what 32m does to people. Time for a rest

Hey _Mat_, I was waiting for someone to notice that. I honestly only used it for the ramdisk. I tested with LPM I think it was called in there but it made no notable difference in efficiency. Also, the previous session when I was cold and on the limit, I kept BSOD when opening everything so the less I had to do, the better. I don’t believe it was a program issue, just not all the cores on the cpu were happy with load at 5750mhz. Even this one I changed to 32bit CPUz to make the screenshots quicker and less load. I found that I could achieve 2 second more efficiency than my usual technique by opening in benchmate, then closing the main program, run my Waza and start my run. Every run was within 0.2s consecutively this way. For example, at 4.2ghz, with my usual Waza run, I would be 7m58.6s, but using benchmate with real-time, cpu affinity to my select core (core4) and ramdisk only, would be 7m56.3s at its best (with Waza of course) If I knew how to setup ramdisk separately I would try that. If anyone can explain how, I’d be happy to check the efficiency that way too while I still have the CPU. im not sure that would be considered as altered at all, but happy to share any of my findings or technique for full transparency. Can even image my OS if you would like to check from your side.

Can you still use Benchmate in those if we chose?

FYI. When I started my session the other day, I was having some strange BSOD happening (was a voltage in the end) but tested 1566/3133C10 setting at 5.5g and was at 6m15.9s. weirdly, I was checking my efficiency at -20 when I started and found that I had lost 0.6s to 1s at 4.5G from the day before. Spent maybe an hour with warming and trying different ways to retrain and couldn’t recoup that missing time. Moon phase or day can really make a difference. I had a 3600 profile set to test too but LN2 was limited. Also when trying for 1667FCLK moisture under the CPU came into play and ended the day for me, I was warming to -60 just to boot by that stage which was fraught with 00 and 07 code reboots. If I had another 50L on hand I would setup again and retry.

I have same efficiency with 1CCD and 2CCD. disabling SMT helped a little, but I don’t have comparison screenshots for that.
