AMD Ryzen Discussion Thread.

Not a huge ram overclocker as the returns are meh outsode of some benchmarks..(in intel).

Amd doesnt even show past primary last i heard... but my 1500x rig isnt updated either..

 

[infrared]

That's fair enough, cheers I'm looking forward to hearing your impression of the 1500x rig! I presume it's gonna go sub-zero at some point?

The beta bioses 9943 & 9945 show the tertiary timings, but I'm lost with so many settings lol

 

[EarthDog]

Its my son's gaming machine. There is a 270x in it and he only plays minecraft and roblox (9 years old), so... i dont have much to say, honestly. I havent done anything to it except fire it up.

Doubt it will go cold...we will see though.

 

[r9]

Yep.

Still, this pleases me.

As far as CPU-Z is concerned, I'm getting Kaby-lake level IPC (I'm at 4.0, it's at 4.2).

I know it's actually a bit worse IPC wise, but it's pretty to look at. And that multi-threading is a thing of beauty.

Actually in the single core test it should boost to 4.5GHz.
So that makes it 6.7% slower while being 12.5% lower clocked.
According to my math looks like Ryzen has higher IPC, at least in CPUZ.

I'm hitting a brick wall at 3700mhz on mine (3650mhz on previous 1800x). That was only with 1.125v SoC, going up to 1.20v didn't yield better results. Upping RAM, CPU, 1.8v pll, VDDP didn't help, loosening primary timings didn't help.. hmm. I haven't tried upping the VTTDDR yet. I'm going to try adjusting some of the tertiary timings next time I'm having a fiddle. So far 3600mhz 14-14-14-34 @ 1.45v is my best config.

@EarthDog - I'm a noob with tertiary timings, do you know any good guides? Or is it just a case of going through each one with trial & error with memtest86+? It'd take days to go through them all :/

I will quite often take my cues from lower divider auto settings. Gives me an good outline as to what timings work well together then it's just a matter of getting them up to speed. If it's too tight i find voltage won't always help on this compared to Intel. Doesn't play the same game.

Ryzen IPC isn't slow. Kabylake and Skylake just has higher clocks. If you check your cpu-z test it almost matches the 7700k at lower clocks.

What I meant was the IPC is actually a bit worse than the CPU-Z test would have you believe. But no, I wasn't arguing it was slow, rather fast.

 

[Cvrk]

@R-T-B do you think you can hit 3200MHz with any ddr4 ram or just the GSkills on AM4 motherboards ?
Also i saw a yb review can't find,wanted to link it (unfortunately) is showed that the GIGABYTE Aorus did not have a complex Bios . How do you feel about this ? Do you recommend the motherboard or not ?

The motherboards bios has just what you need and not much more. If you want to do "advanced" overclocking it may limit you but honestly it was fine for me.

I can't really say on the ram front.

How is this memory for Ryzen?
https://www.newegg.com/Product/Prod...158190&cm_re=32gb_ddr4-_-20-158-190-_-Product

Or do I need to get the "Ryzen Version":
https://www.newegg.com/Product/Prod...158242&cm_re=32gb_ddr4-_-20-158-242-_-Product

It's like $20 or $30 cheaper than the competitors, thus I was seriously considering it. Plus I think it would work with threadripper to in case I wanted to get threadripper vs the current ryzen lineup.

Honestly? Slow. You want faster ram to keep the Infinity fabric the two quad cores talk accross nice and latency free, or so I hear. DDR4-2400 is a bit slow IMO.

 

[trparky]

Anything less than DDR4-3000 and the Infinity Fabric in the Ryzen chip is going to cause performance issues.

My suggestion is this RAM... Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 Desktop Memory Kit - Black (CMK16GX4M2B3000C15)
Amazon Link | NewEgg Link

And the 2x16 GB version... CORSAIR Vengeance LPX 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Desktop Memory Model CMK32GX4M2B3000C15
Amazon Link | NewEgg Link

*edited for clarity, sorry*

@infrared
The only ones that make a difference are command rate, you're automatically sorted there with Ryzens, primary timings obviously and then the two following, nothing else really:

1) if you can be asked, because it takes a really long time, you should start with the IoLs, they affect round trip latency (it being something you can only affect indirectly, hence the IoLs's importance).

- Fully manual RAM settings, ie each channel's settings added separately.
- As low IoLs as the mobo allows, one channel at a time, starting with A.
- reboot, it will hang.
- clear CMOS, 'cause it may never boot again (hence my saying if you can be asked, when it hangs because of IoLs, it really... hangs).
- load last stable, again channel A, again IoLs, just one notch up.
- reboot, will probably hang

Until it doesn't. Once there, set the other channel to the same exact IoLs, reboot.
If it hangs, remove CMOS, default, load stable, increase voltage slightly* until it doesn't. Both channels must be the same, if voltage doesn't help, you need up both one notch.

*only increase voltage to match the second channel's IoLs to that of the first. As far as the first one goes, you only test to see how low it can boot with, don't mix it with voltage, this is a 'can or cannot'.

2) Then you go for tRFC, that one's just like the primary ones, increase voltage, lower it, test, rinse & repeat.
(occasionally, slightly increasing [yes, increasing] TREFI and TREFIx9 might help in attaining stability without increasing voltage. Depends on your patience; emphasis on slightly and never lower them).

The rest you won't even feel, not even in purely synthetic benchmarks. Only e-peening

 

[infrared]

Hold up there trparky.. For the 32GB kit, at 3200mhz and $50 less, @Rehmanpa could get the G.skill flareX 2x16gb 3200 kit. Amazon US link
Which is a lot more likely to run happily, I suspect you might not have as much luck with the Corsair LPX 3000mhz.
Fail! that was a 16gb kit, wth.. Sorry, go about your business lol.

Edit:
Spot on, thanks for the tips and advice @Johan45 and @Aenra , I'll put that advice into action tomorrow

 

[trparky]

I've checked several motherboard memory compatibility lists and the 16 GB kit is supported by many boards.

 

[infrared]

Yeah, sorry, I'd been looking up the 32gig flare x kits and thought I'd come across a bargain.

 

[trparky]

Yeah I swear you pay more for that AMD logo on the side of it.

 

[Aenra]

Guys you're rushing..the 2x16GB Flare kits are not on most mobos' QVLs, that's true, but that's simply because they didn't test them.
You go to the GSKILL site, check their QVL, you might be surprised. I was.

Who tells you what they tested and what not and whether they could be bothered to post their results or just.. didn't care to? I know i haven't, couldn't be asked really.

Did you even go to the manufacturer's site before coming back here to post me some 'anonymous' info?

edit: My flares weren't on Gigabyte's QVL, were on GSKILL's. They worked flawlessly. Still do.

 

[trparky]

More than likely someone already posted that your Flares works with your Gigabyte motherboard.

 

[infrared]

TBF the link trparky put up is pretty specific on serial numbers and cpuz validations.

The 2x 16gb Corsair lpx kit trparky found (CMK32GX4M2B3000C15)
http://rymem.vraith.com/detailed_ram/747
They seem to be topping out at 2933mhz, not bad though for high density sticks.

There's no results on there yet for the flarex F4-3200C14D-16GFX yet (which would be 4x8gb).

 

[R-T-B]

The part number is similar to mine, which is presently running 4 sticks at DDR4-3466.

 

[toilet pepper]

Does anybody know if Ryzen just loves RAM speed or does it also have gains with lower latency?

 

[R-T-B]

You'll get gains from lower latency, but you'll get more gains from ram speed because the Infinity Fabric will run faster.

Of course, you need to be able to actually get the IMC to that ram speed.
