I feel like such a newb - neg offsit on what?
vcore offset minus - (not +)
Man of Honour
On your Aorus Elite, in the BIOS
Set CPU Vcore to Normal ( from AUTO )
Then enter a negative value in the field below called Dynamic Vcore(DVID)
I changed from a "fixed" 1.352v to normal -0.018v offset and I got 7203 & single core was 523 (took about 5mins). I tried wacking in -0.144v and the bios auto-reset itself after a failed post. It might have been the fact I set VDDP back to default from +0.2v. I'm just going to test that.Yeah, stock with a Noctua cooler I was hitting approx 7,200 in CB20
Thx for the help so far, I had no idea my setting for Vcore was hampering my performance.
Edit:
23 Buildzoid's recommended PBO settings. https://www.youtube.com/watch?v=G7Z7bJJcCNY
If you look at screenshot 23 here:

It shows Buildzoid's recommended setting for PPT, TDC & EDC, and his PBO scaling factor. I'm hitting 142w PPT which I know is the limit for 105w TDP processors (from watching gamer's nexus https://www.youtube.com/watch?v=B7NzNi1xX_4, I forget the timestamp). In Buildzoid's video he actually gets some benifit from his settings (not captured in SS but is in video), whereas gamer's nexus using the PBO+auto oc found virtually zero difference.
Oh and I just hit 7075 (523 single core):

-0.144v aint gonna work. But try -0.0625v that has been golden for a lot of us, couple hundred more in multi and doesnt effect single core.
I easily net 7400 sustained and 7450 when nice an chilled. Having custom or AIO helps, as I think it doesnt boost as much when it starts going over 50/55c...
I've tried other settings, feel educated correctly enough to set them, but I get worst performance. So I think it is them not me, so to speak.
Man of Honour
-0.0625v was a good point for me as well, dropped temps nicely too 
That is the level of detail my brain needs - thank you !
How you getting on?
I got the power over the 142w limit, it didn't make a huge difference in performance but it adds up. Check my settings under 09a to 09d. I realise that manual overclock is superior, but I will just leave it like that while I get from 3733MT/s to 3800MT/s. I've already tidied up my DRAM calculator settings so it might work when I change the memory, and Fclk or is it Uclk (1 needs to be locked to the other's speed) to 1900Mhz. I am around 1099mV for SoC dynamic vcore and haven't changed my timings from 3666MT/s safe yet.
I was watching the Patriot Viper Steel 4400 kit as Buildzoid recommended them, and I got 2 of the kits when they were ~£133 they are now down again to £136 ex vat from rainforest. 4 dimms give a clk for clk boost over dual channel.
It took longer to update my imgur post than in the bios and test it:

Some improvements on memory please. I'm on 214.70 for default.

@Megatron I do not know what memory you have but those timings look awfully loose hence your low score.
And if I go to 3800 memory and IF we get 194.28
https://1drv.ms/u/s!ArMHGD-yylU7gdsSmDNRkhcs7XW1Rw?e=fabJKV
I now see you are using Safe settings from the Dram calculator which explains it. All mine are on Dram calc Fast settings

Lol. Impressive. I can't get that low. I get error in hci and karhu after a few hours.
Edit: reading my post above I've repeated myself alittle here lol.
I need to update my imgur post with my system specs. I did say what RAM I'm using (Corsair Vengence Pro RGB (Ryzen optimized) 2 x8GB M2Z3600C18) here: https://forums.overclockers.co.uk/posts/33576939. Also I'll link this just incase u didn't know about it (Ryzen power plan): https://forums.overclockers.co.uk/t...000-series-cpus.18874054/page-4#post-33580106 & my summary of it: https://www.techpowerup.com/forums/...md-ryzen-new-developments.261243/post-4259523.
I am actually waiting on 2 of the kits you are using @Shac (got them for £132+vat from the rainforest and they're £136+vat now after going up and down). So I'm not really fussed with the timings of these Vengence Pro, at least until I try 3800MT/s. These are Micron e-die so not as capable of low timings as Samsung B-die, but there are performance gains to be made and considering I'm currently running them at 3733MT/s and there is a review on the storepage of getting over 4000MT/s I have not reached their potential.
Here's another post you might be interested in (about vtt setting in Gigabyte Aorus Elite X570 bios + buildzoid's PBO settings and how to enable them): https://www.techpowerup.com/forums/threads/ryzen-dram-calculator-by-1usmus.246327/post-4259156
Also there are some new X570 chipset drivers from AMD that gave a performance benifit coupled with that powerplan: https://www.amd.com/en/support/chipsets/amd-socket-am4/x570
BTW 4 dimms give better performance than 2 @ same clock speeds.
About my timings. I'm on safe 3666MT/s preset timings @ 3733MT/s. I might even have to loosen the timings (i.e. set correct DRAM safe values for the higher clockspeed) to hit 3800MT/s. Iirc the first time I tried I was just unstable on the desktop after doing memtest #7 and "testmem5" and memtest from within DRAM calculator. I'm pretty sure I needed to bump the Dynamic SoC voltage to stabilize the infinity fabric @ 1866MHz, and definitely needed to lock it's clock to full speed (or 3 second stutters). I've been meaning to test 1900MHz Uclk:Fclk:Mclk again but I had to revisit some of my settings and get PBO working. I think timings and possible manual overclock (it specifically states power saving states are respected in the bios tips text) should come after settling on a Uclk:Fclk:Mclk speed. However I've already got my cinebench score bumped up from this thread (just set a dynamic negative offset vcore instead of a fixed maxed voltage limit; also made this adjustment to my SoC voltage FWIW).
@Shac It looks like you've beaten the inbuilt score for memtest in DRAM calculator @ both 3600 & 3800MT/s. Maybe you should add your score to the spreadsheet?
Definately the wrong thread but still overclocking: Do u have any idea why my RX vega56 stays at about 500Mhz HBM (graphics memory) rather than the 930Mhz I have in MSI afterburner for certain benchmarks, specifically cinebench R15 GPU test and any 3d mark versions I've tried. It seems fair when testing Heaven 4.0 @ ~1500Mhz GPU and full HBM speeds. Its fine ingames aslong as the CPU can keep up @ 1080p. Which ofcourse I'm working on currently.

If you didn't manually check your settings after using the calc then u could have more under the hood.
This post also shows a score beating the memtest preset inside DRAM calculator but he did tighten his timings and only has 16GB ram:
https://www.overclock.net/forum/showthread2.php?p=28441348#post28441348
but since its an easy test the numbers are not comparable.
@megatron
When you have the Vipers fitted.
In Dram calc be sure to enter them as profile version 1 and memory rank 2.
Only use the FAST option I mean why would you choose anything slower
As soon as you enter 4 sticks of ram the motherboards will treat them as dual rank even though they are single rank modules.
If you persist in using single rank and run the calc it will not be stable.
I enter in everything on the Dram MAIN page.
I do not enter any data from the advanced page ( I never even look at it)
Especially as it suggests CAD bus timings of 0 which is totally different to the data on the main page.

A few posts later he states stupid voltage for his ram.
I don't care for those numbers he has posted, they are meaningless bench numbers.
