Haha subtiming that is the one i not familar set.. yeah board auto set..
Later will download this asrock utility and check the subtiming
I mean was 3900mhz 17-18-18-38 vs 4000mhz 17-18-18-38
3900mhz get around 44ns
4000mhz get around 46ns
4000mhz 17-18-18-38 didnt test stability yet cause bad latency
3900mhz 17-18-18-38 cannot get stability no matter what voltage
3900mhz 16-18-18-38 now testing halfway very stable so far at 250% hci memtest... still running

Looks like my board hate 17-18-18-38 and love 16-18-18-38

Get the ram speed stable with the vcssa/vccio. Then only tweak the main timings with slight adjustment on vcssa/vccio. Also at this point u can gauge main vs secondary timings diff (tref.. trfc.. tfaw)

Vcssa/vccio voltages can affect cpu/ucore voltage vice/versa.

What affects vcssa/vccio is related to rtl/iol pairing with tcl/twcl pairing.

Cl17-17-17-37 Binned bdies dont do well on cl19 .. because of twcl.. they fab cl17 to cl 14.. cl18 is somewhat passable.

My experience in giga master z390 board. Dont always use that relax memory training preset.. it actually makes things worse .. try diff training preset..

Another note. Found this today
Ignore the 3900x ..



So is that a oced or stock velocity all core boost 4.9ghz@1.25v. But the temps look pretty damn good for vietnam.
Dat cpu should be able to do 5.1 easy.


Intel has done some optimization here..

10900K vs 3900X vs 3950X







Soruce: https://www.bilibili.com/video/BV1ZC4y1H7NC/

TL;DR:

10900k is 3.3% faster than 3950x and 4.1% than 3900x in gaming.
3950x and 3900x beats it by a lot in other things.

10900k runs hot even on a 360mm aio

Power draw;
10900k = 338w
3950x = 306w
3900x = 263w

Abit nutty eh this reviewer

His ran high ram clock tight timings for ryzen with high flck
But the 10900k only 4kc18 with probably stock uncore (4.3).. suprised he didnt do 4400c18 with uncore 4.9ghz
To make the imc pushing part more or less at peak for both intel and amd.

i wonder.. is it because of the insane phase/vrm config atm that contributing to super stable power delivery by distributing the heat...

ASUS
EXTREME 16x90A
FORMULA/APEX 16x70A
HERO 14+2 x 60A
STRIX 14+2 x 50A

MSI GODLIKE 16+1 x 90A
MSI ACE 16 + 1 x 90A
MSI UNIFY 16 x 90A
MSI UNIFY ITX 8 x 90A

GIGA EXTREME/WATERFORCE/MASTER - 16 x 90A
GIGA MASTER - 14 x 90A
GIGA AUROUS ULTRA - 12 x 55A

ASROCK Taichi 12+3 x 50A

the numbers are just nuts... for a possible 300w cpu.
some of the vrm/phases are like those on the refreshed x299 / TRX4

MSI going all out with 90Amps

just for comparison
the z390 formula hd like 8+2 phase 50A....


This post has been edited by cstkl1: May 19 2020, 09:14 PM

Those phases might be overkill, perhaps we don't even need more than 12 phases for LN2 LOL
Look at EVGA Z490 DARK, it will have just 12 x 60A probably to destroy those 16-phase boards.
But I believe to cater for insanely OCed 10-core 10900K, hence the 90A is there for robust supply of power, high effectiveness and good quality MOSFETs for better heat tolerances.
BTW, it's been a long while since we last heard about OCF, where's Nick Shih?

Wei dat evga board 10layer e-atx 18 phases..its totally bonkers.

From what i read msi gone teamed config.. so its the same as asus but not sure got doublers or not.

Also looks like because they got whipped on the x570 on vrm.. this time out they beefed everything.

Most probably married. Kids. Realized asrock paying him do extra work foc. .. lol

Another note
Extreme, hero and strix all come with vrm fan

Another interesting part


The xii hero=X570 hero= z390 apex ignore the igpu part. Its like they just said F u buildzoid and did this. Lol

EVGA Z490 DARK has 12 phases of 60A vCore MOSFETs hehe. The rest are power phases for iGPU, SA, IO.
Z490 Formula/Extreme/Apex has 16 x 70A/90A/70A respectively.

^ I will put this at Post #1 for ease of reference.

ah so thats where you got dat info..
couldnt find it in the spec sheet

hmm that google sheet is terrible... totally incoherent

32GB (2X16GB) 5000MHz C18 anyone?

https://www.corsair.com/us/en/Categories/Pr...32GX4M2Z5000C18

so these are double sided??

crazy.. with ddr5 incoming no point...
i still think the sweet spot is 4200c17 or 4400c18

So, NDA for 10th Gen processors has been lifted today!

all gila voltage. all unstable. if push uncore the cpu instability will surely can see.

but hmm that means this cpu has almost zero or little freee margin oc. generally that 4.9ghz should be using a vid 1.2-1.3... so 5-5.1 can but this case..

It turns out that ASRock played tricks on HWBot scoreboards.
They are using an unofficial 2-DIMM Z490 Aqua for submission, which is unethical because using the same name as the 4-DIMM retail board. This is cheating!



https://hwbot.org/newsflash/5143_2_days_aft...getting_broken_

in one of the those yeah... indeed not ethical.
however it seems that he has been using a board with 4-DIMM layout, too.
