Ryzen - Return of the Jedi

[easyrider]

On a b350?

the question is rather vague volts speed etc......

on x370 ive done hours w/temps in pics.......just look through thread.

Hi Mate

Can you link to them I cant find them?

What are these results based on? Cheers

That's silicon lottery results from binning.

Its only on page 1 like first result in review look harder

Prime 95 2hours in temp readings, I think now you can start to see one of the limitations. Oddly enough heat out of the heatsink feels like 40-45c. My 290x's in crossfire on water dump 50C loaded after a few hours. I'm very familiar with what the temp feels like. This feels cooler.


Highest ive seen 77C if testing 24/7 stability good cooling good paste good mount.

Ive seen much worse bad mount and or excessive voltage.

Did 4ghz require a big bump in vcore then?

Linky? Forgive me if this is a stupid question.

Did 4ghz require a big bump in vcore then?

preety much will most likely for all chips.

I would not exceed 1.50v for 24/7 stability testing. I personally don't feel the gains are worth it plus the chips just really don't like it.

I'm noticing that the l3 cache write speeds in aida64 are up and down alot with what I'm seeing with the pics you guys are posting.
I'm not sure if there's something to that or not.

Also, I don't know if you guys heard, but there's supposedly some kind of sleep bug going on with these boards.
The one dude that found it, has his rig at 4ghz, after sleep and wakeup, it changes to 4.2ghz and "seems" stable.
I wonder what would happen with a much higher clock on ln2, maybe possible to get 5.5ghz?
Or dead parts lol, who knows...

One more thing, if there is truly a rom of sorts on the cpu...
Getting it super cold could cause the chip to keep data when it's supposed to be changed.
The only reason I know is because I saw some goofy video some years back on spying, people would take out the ram and put it in cold ice or something, and replace the ram with there own, so that they could grab the mem contents.
Kinda of a weird thing but just saying, rom's and ram, when they get cold, they retain data to the extreme I guess.
So if for example, you bsod and have to reset the cmos on a ln2 session, the reset might not apply correctly.
I don't know for sure, just saying this could be a possibility.

[chew*]

The l3 is buggy in version we are using. Only l3 is fixed in new version. Non issues. Does not effect read write copy. Plus we have tested same version.

We are both on asus. Sleep bug non existant not to mention hpet is on and in performance mode on sleep does not happen.

@Chew - you are a bad man . I had put a Ryzen build off for a couple of months but have found pricing for the B350 to be practically irresistible @ roughly €100, €375 for a Rz1700 and some memory and I can start playing at under €600 + I have a couple of Sabertooth (R2 and R3) and a couple of FX's to that €600 to bring it down even further.

Interesting to note that Asus have a message on the spec page for the board reading like this

"1*Due to the limitation of AMD Ryzen™ processors, memory frequencies higher than DDR4 2666 MHz are supported only when using one DIMM."

Looks like you have blown that away with the TridentZ you are using.

@Chew

Read the qvl for the board. Quite a few sets of over 3200 work even shows dual channel. Im betting thats a CYOA move as it seems some cpus imc are not great.

Its preety odd to say the least but when shopping for low end x370 i was seeing not so good qvl listings.

2933 at best.

3 b350 boards in 3 different brands qvl 3200 np

People with contact at MB makers should make a case with mb manufacturers, for a B350 mobo with some quality components ,good PWM and more sata ports.
I dont need leds or fancy looking stuff, i also dont really need x370 or sli .A mobo which you could recommend to anyone not doing world records on phase or Ln2 but with solid Oc on air and water.As ryzen is multimedia oriented, there should be 8/10 sata ports 2m2, dts .This kind of mobo would sell well .Wonder if there are more models in the making, or for what we see is what we get.

[chew*]

I can try and ask but obviously the company will want a profitable product.

A beefy pwm simple short and sweet b350 would probably be easy enough but it would put its cost closer to low end x370.

I kinda have one upset with me right now so i think they are out of the question for the time being...

Its not easy being brutally honest, someones bound to take offense but thats just me being me.

How they choose to interpret it can be critical. They can take it offensively or constructively.

The latter of which can only bring better products to us.

[chew*]

Checked memory compatibility on ASUS b350-plus today.

As I suspected QVL being biased towards Samsung has its costs......Avoid Hynix based Ic's on this board.

Luckily the Samsung based IC's offer better timings @ better speeds anyway so really not a big deal unless your trying to be super cheap about using this board.

Fyi there is a clue as to what happened. I'm going to look into it further. PS/2 drop is to much of a coincidence.

Laymans terms PS/2 operates off 5v and ground.

Time to get technical



EDIT Ok so confirmed 5v and ground on ps2 so that was a dead end. Tired dig deeper after some sleep.

Ok insomnia Wins but made some progress. Found a hot spot.

The culprit is in this area. I'll poke around with the dmm tomorrow.

Ok, I now know how this aida bug happens.
Here I've booted with 22.5 multiplier and then raised in Windows.



On the other hand, I can share info about 4x8GB B-die (the screenshot above is also with 4 slots populated).
On Asrock AB350 Fatal1ty K4 I couldn't boot above 2400 divider.
On Crosshair it was possible to boot 2666 with standard dividers.
Raising bclk I could boot 3133MHz with lower dividers. To get 3200 I had to raise it in Windows.
Can't set lower than CAS14 with 4 slots populated.

RAM is 2x8GB 3600C17 and 2x8GB 3733C17.

[chew*]

Yep i had charged do via same method. Seems msi is not affected like the asus by that bug.

In other news i preety much pinned down the issue with my gaming 5. I want to give them sometime to look into it however.

I have a theory on how as well but lets see what they say first.

Im preety confident it would be impossible to hard mod mine back to life or i would have done it already.

[MattiasNYC]

So I have two questions for those in the know.....:

1. Am I understanding it correctly that as we pack the boards with more memory the maximum speed at which we can run the memory decreases? I mean, generally speaking....

I'm am still cautious about a new purchase since I actually have to make money off of the next machine I get, and this is an issue that might concern me. I'd ideally want no less than 8GB per stick and at least 16GB to start. But now I'm sort of fearing that I'd be stuck at significantly lower speeds if I eventually move to 32GB RAM.


2. I get that the fabric that connects the CCXs is tied to memory speed and also PCIe. What I'm still a bit uncertain of is under just what condition PCIe 3.0 throttles down to 2.0. (?)

If anyone could either briefly explain it or point me in a good direction I'd be happy...

[chew*]

Ok infra you got 4x4 covered. I will put in work with double sided B die 2x16g.

Got a good deal on these and since this seems to be a bigger topic than I expected......

Keep in mind this is a little B350 so....

No post 2933, no post 3200.

No post 2666 14-14-14
No post 2666 12-12-12

But at least i'm maxxing out AMDs recently announced spec for this config. Anyway i'm looking into it Mattias but as I feared double sided will be a tad troublesome.

Question: are you doing all your RAM tweaking in UEFI, or are you using Ryzen Master?

[chew*]

Bios currently,

Ok so there is room for improvement in bios updates.

This one is rather flaky USB wise (beta) but there is a performance gain so they did not just slack something to run tighter.

Still can't run higher, that could be cpu specific however.

2666 12-12-12 DS 32g

Has anyone seen this? Prime95 for Ryzen.

Thx for the heads up. Maybe i can get it to trigger imc/memory errors now instead of just bsods.
