AMD Zen 2 (Ryzen 3000) - *** NO COMPETITOR HINTING ***

[robfosters]

Just been reading the steam stats for July. Looks like a lot of folk are opting for the 3600. 6 core cpu's the biggest increase this month. 12 cores have only increased by 0.01%. That's probably a lot to do with the terrible stock shortages though.

Oh so I can unlink them, I tried this on ryzen master and it wouldn't let me, so I can set the if in the bios to 1800 or 1900 and the ram to whatever I want?

You can. But I think your get a latency penalty if they are not synced.

Watch these videos:

The best parts are the first bit of the first video and the part in the second video where he shows the chart. Essentially ram speeds of 3600MHz plus you should have your FCLK synced. It's only beneficial if you cant get your ram to run faster than 3600MHz.

So find your max FLCK and then set your ram to 2x that.

You can see the discussion here on reddit.

I do all my overclocking in the BIOS. I've never loaded Ryzen master up ever. Am I missing anything?

I've given up in the end.

I've got timings that do work.

16 16 16 16 36 - 3733MHz - 1.4v

This gets me in to windows and gaming

Still to prove 24/7 stability tho.

For my "minimum viable" stability test I use OCCT AVX2 for 5-10 minutes plus a 10+% coverage run of MemTestPro. Once I have one or more "minimally stable" settings, I run MemTestPro overnight to prove stability. Otherwise you're just asking for trouble: I've already had a profile that passed the "minimally stable" tests then crashed twice in games.

Well I've tried importing my Tahiphoon RAM readings into Ryzen DRAM Calculator and it's suggesting some looser timings than the stock V1/V2 settings. So I entered everything I could into the BIOS at 3333 MT/s: suggested timings, voltages, PMU training options, and procODT. Doesn't even POST.

Also tried DRAM voltage at 1.4 and 1.45 V with same settings, nothing. Never gonna happen I guess, I lost silicon lottery perhaps harder than I ever have before.

Same for me about the only thing I’m able to do is to keep the xmp timings and increase the speed.

I’ll leave it at xmp and wait until things have matured a bit I think.

I finally caved and went for a x570 board just to make sure.

You got your X470 Gaming Ultra up and running with the 3900X though, didn’t you?

Yeah it's running at stock perfectly fine and I would be happy for that. But as for trying to boost or overclock manually its not going to happen, it hits 2 of the 3 limits on ryzen master, those amps things are at 100% when it's on pbo mode or auto overclock and it struggles to go to 4.1ghz multi or 4.2 - 4.25 on single.
I would myself, being a tweak addict, feel much more comfortable on a board that could easily handle this chip or more.

I think the 470/450 chipsets are fine for 3800 and below, but the 3900 is definitely performing significantly better on 570. I'm on the 570 ultra and getting lots of cores regularly pushing 4.55 to 4.61. Is it the VRM? 8=3 (470) v 12+2 (570).

I’ve just upgraded to A X570 pro gaming Carbon ready for the 3900x

Does any one know what voltages can be tweaked to push the FCLK higher?

Second question.... How do I go about making my timings tighter? I don't have a clue where to start. I just copied the 8 Pack 3600MHz timings and used those on my 3200MHz kit.

16 16 16 16 36 1T @ 3600MHz @ 1.4v

Try 14 14 14 14 36, maybe up the v to 1.42, then check if it's stable with memtest

My motherboard won't power on with my CPU in the socket, but otherwise it powers up fine.
Any suggestions?

I've checked to make sure there's no thermal paste on CPU pins, none bent etc.

That's a no go. Even with 1.45 dramv the PC wont post. I think I should just be happy with what I've got and call it a day. Too much fiddling, rebooting etc....

There is still one avenue to go down to increase FCLK and that is CLDO VDDG voltage. It is responsible for the IF.

Which voltage would potentially aid in stabilizing high FCLK frequency?
Matisse introduced a new voltage adjusment, called cLDO_VDDG. VDDG is the fabric voltage.
At default it is 0.950V however, some motherboards might increase above the default level even at stock settings.

cLDO means the voltage uses a drop-out (LDO = low drop-out) regulator.
Most cLDO voltages are regulated from the two main power rails of the CPU. In case of cLDO_VDDG and cLDO_VDDP, they are regulated from the VDDCR_SoC plane.
Because of this, there are couple rules. For example, if you set the VDDG to 1.100V, while your actual SoC voltage under load is 1.05V the VDDG will stay roughly at 1.01V max.
Likewise if you have VDDG set to 1.100V and start increasing the SoC voltage, your VDDG will raise as well. I don't have the exact figure, but you can assume that the minimum drop-out voltage (Vin-Vout) is around 40mV.
Meaning you ACTUAL SoC voltage has to be at least by this much higher, than the requested VDDG for it to take effect as it is requested.

Adjusting the SoC voltage alone, unlike on previous gen. parts doesn't do much if anything at all.
The default value is fixed 1.100V and AMD recommends keeping it at that level. Increasing the VDDG helps with the fabric overclocking in certain scenarios, but not always.
1800MHz FCLK should be doable at the default 0.9500V value and for pushing the limits it might be beneficial to increase it to =< 1.05V (1.100 - 1.125V SoC, depending on the load-line).

So based on this I should just be happy with my 1800 FCLK and call it a day. Enjoy the pc rather than endless tinkering.

Double post.

OK, so motherboard powers up with CPU in socket after swapping out the CMOS battery.
Still fails to POST, and EZ Debug has CPU lit up, like it has when I've powered up without CPU in socket.
GPU powers up correctly, but no signal going out.

What cooler have you got attached?

If it's an aftermarket monolithic brick, this can sometimes warp the area around the socket - and can cause similar issues to this. (rare cases stock coolers - but would be surprised on an x570).

You could test the theory by pressing the heatsink to the CPU to see if it has any life i.e. without heatsink fixed to motherboard - won't be an issue for a lightning test.


**are you mainlined into the wall? If not i would try. If not possible try a different extension cable. Same for kettle lead if new PSU. (all reaching - but good to rule out).

Missed this post as had my reply open for a while before submitting - but would still consider the above.

Insight much appreciated. TBH I might just pass on the 3### then and see what the 4### are like instead next year.

If I could just pop in a 3900X and tweak away I think I could justify the upgrade from a 2700X, but if I need a new mobo too, I find it a harder pill to swallow.

It’s not like my 2700X is a slouch anyway. Mostly just gaming at 4K with a 2080Ti.
