I was playing around with 2 sticks yesterday, just messin around.. I wouldn't call this stable, I have things a bit too tight for that. I really like this board for the most part. I wish the lan would be ready to go once the desktop is loaded like every other board out there, and not take 38s to initialize after desktop is loaded or wake from sleep. Gets old pretty quick lol..
Were you trying for your mem to be 1:1:1?
Vin
No sir, my IF is no good over 1900, maybe if I push harder I could get 1933 but ehh.. its not worth it.
I was giving 1.45v, it’s the first time I tried CL12. It didn’t like 3400 @ 1.45 so maybe 1.5v? My kid is playing GTAV right now at cl12 because I had to go to the store.. he’s not yelling yet so it’s looking promising lol.
I'm not sure what I'm doing wrong. I cannot get under 10 minutes. How fast do you have to wind up the CPU? I'm at 1.387v on the CCD and I don't really want to go higher lol. For this is fine but AVX is brutal at these volts..

Well, bump the bus frequency a tad. Let's see if she'll stay stable for just a tad more frequency maybe.
Like 100.05, 100.10, 100.15 ect ect

Apolodies upfront for the extended post.
I will try here to make a global presentation of what and how to, for Ryzen 3000 and 5000 series processors and motherboards and memory sets.
1) PROCESSORS
These cpu's are SOC cpu's with a completely different architecture in design than anything we have known up to now. Extended tests on ambient have proven that max clocks and fine tuned mems and board give only a 10-12 % better performance than all at default settings. This means that AMD has done a very fine job and the amateur user has no problems getting out of his system 85% of max possible and if the mems used are good ( Trident Z Neo 14-14-14-28-1T at 3800 - designed for AMD ), then simply applying XMP in bios will present a fianl performance that the amateur user will have nothing to be jealous about compared to a fine tuned expert tuning.
Having said that, let's leave it behind us and see what more can be done to squeeze out every drop from a given setup.
There is a very significant weak point with the IMC of these cpu's. Forget everything you know about tuning memory controller and mems the Intel way. Also forget benchmarks like SuperPI, Pifast and generally all single threaded benchmarks that need very high clocks and very fast and tight mems to shine. Intel territory.
Before entering the "how to" section, I will boldly state upfront that all software, supposedly improving performance inside the OS, are a piece of garbage. Even Ryzen master. For the lucky owners of Asus boards, Turbo Vcore version 1.05.03 is fully compatible and you can work with this for changing clocks and voltages on the fly.
HOW TO. Disable in Bios Precision boost overdrive. DO IT. Disable in bios Power down mode and gear down mode. DO IT.
Set Vcore to 1.3750 and start from 4.5ghz cpu speed. DONT TOUCH ANYTHING ELSE for the moment. Enter OS. Make a few runs of CBR15 and Wprime 1024. Check temps. Open Turbo Vcore and raise speed to 4.6. Repeat. Stable ? Raise to 4.7. Stable ? Raise to 4.8. Tough but possible if the cpu is good. After settling to a stable overclock without exceeding 75-80c, reboot and apply your speed in bios.
FCLK time. Here we have two options. Symmetrical 1:1:1 ( meaning that mems and uncore will run at the same speed ) or assymetrical where we can set mem speed wherever convenient and FCLK to Auto and let bios do its thing by adjusting uncore to 1/4 of mem speed.
SOC mode must be enabled to be able to adjust the Vsoc, which from my experience on ambient and DICE is useful up to 1.25V.
Despite the fact that most users consider the symmetrical mode as best, I have strong doubts. Expecially if you go cold and own mem sticks of high potential.
THERE IS ABLSOLUTELY NO SUBSITUTE for mem speed and timings. FCLK, is almost of no importance when you can ( if you can ) run at 4500 and above mem sticks. Two examples here : a) 4533 / 17-17-17-37-2T, 1.525V, no maxmem needed. b) 4600 / 14-14-14-28-2T, 1.85V, maxmem set to 4000mb.
Back to symmetrical tuning. Best case scenario. FCLK set to 1900, mem speed to 3800, primaries to 13-14-14-30-1T.
Scotty asked if there is a possible setting for 12-12. 12-12 means that maxmem will have to be minimised to 4000. 12-12 is useful for single threaded high speed benchmarks and Geekbench benchmarks. Nowhere else. Since we are talking mainly for ambient and high clocks are out of the equation, pushing FCLK to 2000 and mems to 4000 ( for symmetrical setup ) with 12-12-12-28-1T, means that you will have to pump 1.85V at least to the sticks, with minimal returns, except for GeekBench.
3600 or 3800 at 12-12 is another option with 1800 and 1900 FCLK respectively, but you will still have to pump 1.65v and up to 1.75V to the sticks.
Secondary and tertiatery timings on ryzen is a complete nightmare and I sincerely had to go back to school to learn what works and what doesn't. At some point I will write an article with pictures from the bios about sub timings, but please keep in mind that what worked for me might not work for you and it all depends to the quality of the IMC and the mem sticks.
Questions ? Shoot and I will be more than glad to reply.
freeagent, after looking at other ambient scores on the bot for SP32 I ain't got no answer other than some form of throttling, not really a lot of information though? I've only had an AM4 on ambient for an in house comp here and to get through the WP32 portion I dropped my thermostat from a summer setting of 74f to the winter setting of 68f, did get two good nights of sleep out of it.
If your running your daily don't know how much you're relying on windows and bios to control your thermals nor how much software you have running. Looking at your screenshots I'd be expecting something in the mid to high 7's
MrPaco "hey Pete its not called hoarding, its called connoisseur savior of all things computer related"
Once again, Thanks George. Your guidelines are pretty much right on. 1.375 vcore, temp CB benchable @ 75-80c, Ram/FCLK @ 1866 @ 13-14-14-30 1T It's about the best it gets on air. Can run the tough benchs @ 4400. 4500-4600 on the short ones. Need to put the chiller to this chip to do any better.
Loved by thousands, hated by millions. Warp9-systems, the anti-Christ of competitive benchmarking.

The chiller will be nice cause you'll probably net the v-core lower on average at the same clocks.
is there is a PS2 port or you have a real USB 2.0 PCIe card, it's not a big deal. my USB3.0 drivers just don't stick. so I use the 2.0 for everything. and I move my KB to a MB USB port when I need to use the bios
Jon, 1.60Vsoc. Do you intend to kill that cpu ? Max on ambient is 1.25v Max on LN2 is 1.45V
Scot,
I have not shimmed in because the board does not leave much to really tweak and make a difference. Neither your cooling.
I would try to have a stable 16-16-16-36-1T. Secondary timings on this board is only by trial and error and any amateur suggestions better be ignored.
If it can run FCLK 1800 with 1.20V, then go for 1:1:1. And call it the day. No real reasons to torture the cpu on this board.
I've been waiting for your advice.
I am at 3766 @ 1.5v @ 14-14-14-28 1T SOC is at 1.2v. FCLK will do 1800 @ 1.2v Can I do better on the timings? Is 12-12-12 doable at a decent speed?
I guess that 1,2Vsoc is pretty high. Main problem with (basically the smallest ammount even) Soc overvoltage is the bitchy behavior for higher temps. Every small ammount what is over the needed level is Your enemy. And it's a very strong enemy here. The stability for higher fclk is much more about the vddp and vddg iod voltages. That is what leads for stable working. (for me at least) not the higher vsoc. It makes things worse at real. I think somewhere between 1V and 1.05V Vsoc should be enough for 3600:1800 even for higher. I know every chip is different but I've never seen any Zen2 what needed over 1,1V for 1:1 mem setup. Even for 3800:1900. (ofc I've seen only a few so it's not a fact ) My setup at 3800:1900 My VDDG IOD is 1.05V (not seen in the pic)
Ps. : Sometimes a slight raise on pll seems also helpful. (E.g. from 1.8V to 1.9V or smthg)
I think its up to the CPU what it wants. My 3600XT could do 1900/1900 without touching anything, with 2 sticks. With 4 sticks I could go to 1866/1866 without touching anything. On my 5600X I can run 4 sticks up to 1866/1866, and it gets a little cranky after that. But with two sticks I can ramp IF up to 2166, run out of ram at 2133, but comfy at 2100/2100 with no bump in voltage to SOC. But.. I am a noob and still learning. SO I could just be talking shit..
ShrimpBrime: Earthdog! Overclockers.com!!! Good to see you. Hope everything is good by you also.

Aleslammer: Gas down where I'm at about 60 cents a gallon for a $6.30 (Chevron), haven't seen anything below $6 locally.
Jun 29, 2022 10:54:48 GMT -5
ShrimpBrime: That's $8.33 a gallon for you US folk. $5.50 a Gallon where I'm at. And that's expensive in my opinion.

scruffy1: gah! petrol is > $2.20 (pacific pesos) per litre jere at the moment
Jun 28, 2022 8:31:09 GMT -5
Vinster: really sucks.. happy to have a hybrid car for work.. but the fuel cost in the family van hurts.
Jun 28, 2022 7:00:08 GMT -5
Macsbeach98: $1.87 a Liter here I am in the same boat Vin
Jun 27, 2022 19:28:43 GMT -5
Vinster: That is super cheap... I'm paying $2.05/Liter... so... $7.80/Gal?
Jun 27, 2022 11:20:27 GMT -5
austin86: I have to share this. I filled up my car yesterday at 3.99 a gal, yes 3.99 a gal, a sheetz a few towns over has been selling gas for supper cheap

Macsbeach98: 20c here today and its winter
Jun 25, 2022 22:58:02 GMT -5
Vinster: 32c in the shade, working on the deck is rough.... near 40c in the sun. didn't start until the sun was on the other side of the house.
Jun 25, 2022 19:46:38 GMT -5
Mr.Scott: 33c today and tomorrow with tropical humidity.
Jun 25, 2022 15:58:48 GMT -5
ShrimpBrime: Pretty warm in our area too. Feels good when it's not humid though, Lake Michigan and the Mississippi river make Illinois pretty wet climate.
Jun 24, 2022 21:12:47 GMT -5
george: Midsummer here, and this time not its classic rainy windy weather, but a warm burst, forecast 30°C, for a while.
