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

I had that problem with ABB today, AB works fine on my board.
I think Ill skipp all of this 1.0.0.3 loot and just wait for 1.0.0.4... This is like what 3rd try to get this agesa working ?? :D was standard then fixed now fixed fixedand still not 100% fixed

When im looking at @Illuminist and @opethdisciple situation... One is on Gigabyte motherboard with ABB that i know from persona XP it is PAIN to work with PAINN Could not get my settings from Crosshair VII working on it on my spare build. Ram settings that I posted and ware passing 30 000% ram test no problem.. Would not even boot no matter what !!! But could eb due to crappy 3600 so i went with that one. but hes on 3900x like me and was better on x470 motherboard !!

Then problems on Asus motherboard with 3700x that SHOULD be better than crappy 3600 with good ram kit. But I think in this case its user error :p I bet I could get @opethdisciple rig u and runnign stable by going full on manual mode in 1 day.


Like common I have not even done fresh windows install just took 2700x slammed 3900x set my power section same as on 2700x. And....

:D but as I said i went manual from day 1. I noticed that soem memory timings CHANGE on auto every now and then when you reboot the pc... Gtrat stuff when 1 timing sometimes is 9 other times is 8 and lets say mem cant do 8 so if it boots with 8 you will crash you reboot boots with 9 its stable so ye there is that :D

for 2 sticks daisy chain, Zen2 has been optimised for it over T-top'. Daisy-chain gives higher speed for 2 sticks of ram, T-top' is better for 4 sticks but it'll be slightly slower than 2 sticks no matter what.

And for daisy-chain it's best to use the two slots furthest away from the CPU, the traces are timed for it.

Ok great! Thanks. Much clearer now for me.
 
O ye have a look on bios bottom section of timings and You will see that Channel A got bit different timings than Channel B :) I know that Crosshair 6 was designed more twoards 4 sticks and Crosshair 7 for 2 sticks on pcb level.

Great info!! Do manufacturers tend to stick to design types or does it vary per motherboard?

depends on manufacturer let me find post about the change made:

At a glance, the new Crosshair VII Hero is difficult to distinguish from its predecessor, since the changes seen are relatively few. However, in reality there are quite a few changes, but they are mostly hidden under the radiators or in the circuit board.

The biggest changes to the old model are the second M.2 bay, the upgraded and more energy efficient, more robust power supply and the change in memory signal topology from Asus' own "T-topology" to the more traditional and AMD's current daisy chain topology.

The advantage of the previous T topology is the smaller differences between the various memory slots, and thus the potential for slightly better performance with all four memory slots. Daisy chain topology, in turn, maximizes the quality of the two memory locations at the expense of the other two.

My Polish mate INTEL memtest gamer had time to run benchmark of XMP vs tuned in assasins creed on 5ghz intel

FHD Medium …no AA

So in general AC:O likes nicelly tuned memory on AMD and INTEL.

Could make a good memory tuning benchmark :)
 
Got all core 4.4ghz running with cl 16 3600 , but @Zeed do I need 101.8 blck to make this stable you were saying way back?

Also mini chiplet c 04 c 05 c 06 all stay at 3.8ghz even though I did all the cores, the other 9 are 4.4ghz
ooo ya fakt it up you went /core overclock not /ccx. Its not an ERROR you got 3 cores runnin at only 3.8.
Situation is like that Each ccx is limited to WEAKEST core thats wmy my 4th ccx with core nr17 is weakest and thats why I got 4375 all core not 4400 all core cause of that 1 ****** core....


You cant go /core overclock only .ccx cause thats how it runs sadly.


If it goes for 101.8 I only need it for 3800/1900
 
Also, what voltage do I need for 4.4 all core? I'm on 1.45v currently, that's way to high right lol
1.45 ??? That will fry the chip in heavy load like Steve did from hardware unboxed. Total MAXIMUM for heavy workloads like rendering after Vdrop is 1.35 i would not ever run more than 1.36 on my chip. Not with amount of heavy benchmarking I'm doing !!!

Please tell me how to set it correctly before i kill my pc lol

I told You to lock Vcore in bios to 1.35 with no vdrop and work with that. What You get will eb what You have thats it. Not a clue how LLC is on that motherboard maybe level4 will do if not go max im on max overshot on c7h is 20-23mv from what i remember messured on osciloscope but thats only microseconds does not show on voltage in HW infor.

First voltage then play with LLC setting not other way around or you will do Steve and put frying power in to cpu.

To put perspective with 1.35 volts CPU pulls up to 210 watts image how much can go with 1.45 and no limits :D Thats hy I'm recomending to stay away from auto overclocking on 3900x at lest till bioses are not garbage. That auto overclocking likes to add extra volts over extra volts. I had a look myself and was like **** those volts !!!

If there is some bug in bios with how LLC works on given motherboard it can fry the chip simple as that. You seen posts here where people got some stuck voltage on idle pumnping 1.45 ect.

Okay so I was already on extreme llc so I'm lucky to be alive, I'm going to dial it back to 1.35 on medium llc and start from there.

If it's all good, is it worth pushing for 4.5?apart from the crappy corez

Edit* 1.35 medium llc works 1.28v in hwinfo average of 1.3v 70.c under stress

4.5 ?? sorry to break yer bubble no one here managed that stable. Best all core I'w seen stable was 4.45 volts not suitable for 24/7 use what You had for that CB20 run ?? @andy_mk3 ?? I know You got best 3900x I'w seen around forums.

For me Stable is 1 hour of Aida 64 passes 10x intel burn test very high and 3 passes in row of Ycruncher Pi benchmark.
Thats what is MY stabe. Good enough for one day of constant rendering with power director while mining with gpu.

Decided to test how long this can go on without reboot. So far 26 hours of witch 16 was mining 5 gaming and rest on youtube and internet browsing. Startingh Mining up try 2 get some sleep. See if it is still up in the morning.

Yeah it wouldn't pass cinebench at 1.35v with turbo llc enabled, do I go down to 4.375 or go up to 1.36, 1.37 etc?

I got my 2700x to 4.45 stable, once I get to know my stuff, I can push it pretty well.
I held top vega 64 and radeon 7 3dmark scores also. I'm no zeed, but I'm not too bad
