also, i have 2 kits of memory i am testing bout cl14 3200 kits. 1 is team dark b die single rank, and another is a flare x kit, dated july 2019, not sure if its b die is there any way to tell for sure without taking the heatspreader off and looking at the chips?

lastly i am running 3466 on the flare x kit now, and i have it set in bios to 15, 15, 15, 31, any idea why when i boot into windows it would show 16, 15, 15, 15 31?
You cannot use software to test the binning of memory modules. You would need an oscilloscope for that, as well as the knowledge to understand the outputs. The only thing that you can do via software is verify that the settings you have applied are working correctly.

And the best part is almost everything in bios is on auto except vcore and ram settings! And the benchmarks are with all my apps running like steam, battle.net, icue, ghub, xbox, epic. Funny thing is even though RM shows ccx3 has the best core(c10) of the second ccd its the least oc'able ccx with just 4225mhz.





The bios setup:






Haven't been able to stabilize this oc. Even though CBR20 runs fine but any long run test fails. I find Realbench stress test really good at stability testing. Temps keep rising and eventually reach 90 and instability is detected. I guess im just going to be satisfied with this processor.

thegr8anand DRAM Calculator shows the quality and oc rating. I wouldn't be too reliant on the rating though. Thaiphoon burner shows the ram details, the die, rank etc. Look at youtube on how to use it.


As for the 15-16 thing, gear down mode might be enabled in bios. see if it boots with it disabled. Other wise like me it changes 13 to 14 regardless of it in bios.

edu616 Greetings,

My friend just bought a 3700X. I have a 2700X and remember that changing PBO values depending on settings would net you certain frequencies (depending on your silicon). For Example my 2700X runs at 4250MHz at 1.32V for multi threaded applications like CB R15 and R20. Then for single threaded app it would boost to 4350MHz and voltage would increase to 1.4V depending on how the application works and handles the single cores. Does this still applies to 3700X or is PBO not working at all? What do you guys recommend? He also has this motherboard as I recommend it to him. Thanks!

Yeah. I can only comment for ryzen 3000. And for that it did nothing.

And they are still playing around with temp readings. If you ask me. They made it toooo difficult with their dozens of sensors. Hope they are happy with the approach.
Is there any reason to disable it anymore for 3000 series? I've always disabled it. Maybe I should leave it on Auto/Enabled now.

Spoiler!
uhmm it was NOT placebo before. I have done many testings with first gen Ryzen and Sense Mi Skew. i even reported i could fake the temps with that to boost higher in PBO!
Few weeks ago, i tried again but the skew didn't work for me. Probably its now a placebo for the 3x series. Or AMD killed the whole option. Cant say for sure! Will test with first gen again later!

nick name @mtrai I meant to post this a while ago. Here are my daily timings for 3600Mhz. I have to use 1.48V on DRAM Voltage. Hopefully, you can use less.

These days you at most want to undervolt, and find the best spot between voltages and clock speed. Like, whats the point to go for 4.4ghz on the cpu @ 1.4v if you can get 4.3ghz @ 1.3v. Same with ram. Especially micron e-die. You should just leave all the voltages and settings in the bios at stock, and tweak speed and timings from there.

I did some serious testing my self with all the extra settings in the bios (trying some at the time, or all, or only like 1 or 2 settings). And never did any of these help for errors not to pop up. At most they took a couple of minutes longer to appear.
Samsung b-die (IMC permitting) seems to scale well with voltage.
