Did you get a shiny new Ryzen 3000 CPU?

[tabascosauz]

Anyone else have some weird cold boot behaviour? It's like POST always takes a long time, maybe ~10seconds before it reaches the logo screen, at which point onwards it's easy going.

During this time the CPU and case fans are on, but the board LEDs are off and the GPU fans twitch every few seconds, one usually a second after the other fan. Then about the 4th time around they spin up fully, the LEDs come on and the board POSTs.

I'm a little afraid to set XMP, so I'm just running on JEDEC right now. Both sticks seem to show up okay though. Gonna memtest in a bit.

Do you have that issue with just a single stick of ram installed? Do you have a reason to suspect its the memory?

I don't know. I feel like it's the board. My last kit was a 32GB Corsair LPX 3200 C16, and could only boot with 1 DIMM. XMP was most definitely a no go. It did have the same long POST behaviour when it was working on 1 DIMM.

This time it's a 16GB Trident Z kit at the same speed and timing, and it works just fine at JEDEC with both DIMMs, aside from the kinda long POST. I'm really scared of trying XMP, but I'm gonna do it after I memtest at JEDEC. For science.

I can understand the burden of 32GB of 3200C16, but this 16GB kit should be able to boot right up. Unless the IMC on my 3700X just so happens to be a lemon, I don't think this is the fault of anything but the board. I knew I should have spent extra on the X570 Aorus, because I might have to go back there and exchange it for that anyway.

When it actually POSTs, it's fast as hell. To desktop in about 5 seconds. It's just the getting to the boot logo part that takes a bit of time. Usually announces itself with a big whoosh of the 1070's fans and the white LEDs on the board lighting up at the same time.

 

[biffzinker]

white LEDs on the board lighting up at the same time.

For me it's the white LEDs on the keyboard coming on after the fans on the 2060 are done with full blast. Oh and, longer POST for me since I switched from the 2600X.

The fact that half my boards have underlighting is lost on me because they're encased in 1.5lb aluminium cases it's the thought that counts

I get the feeling that if we had X570s for our 3600 and 3700X, we wouldn't have this problem. Still debating whether to go back and exchange the board; whether this kit will run at XMP will decide that today.

Also, this 3700X is pretty smart when it comes to security and still pretty retarded when it comes to power management huh. It's either max usage 99% and I bench lower than a 3770K, or max usage 100% and I get 50-60 degrees idle, max clocks, and 1.45V idle. Latest F42a BIOS, AMD chipset drivers, Ryzen Master, and Ryzen balanced.

Ryzen does just take longer to POST than Intel, no getting around it.

It's getting much better, but it's still "slow" in comparison.

Now that I've been having these issues and looking online, it seems that a lot of people have slow POST problems. Overwhelming majority of those threads seem to deal with bargain basement boards, and/or Ryzen 2000 on 300-series or Ryzen 3000 on 400-series boards. I built a R5 2600/B450 ITX build for a friend a couple of weeks ago, my first hands-on with Ryzen, and it felt pretty normal. Exact same board too, might I add, just with an older BIOS and its originally intended Ryzen 2000 chip. Maybe the whole backwards compatibility thing does pose a bit of a burden to the hardware? Or maybe NVMe self-test is causing the delay? I put in a SATA M.2 drive for him.

Funny enough, I set XMP and now the delay is down to about 3 seconds. Very nearly Intel POST speeds. If anything, I'd think the JEDEC spec would boot more comfortably than 3200 XMP, but I guess I was wrong. Benches like a beast now.

You're being too paranoid
If something goes won't, just do a clear CMOS.
You're not going to break stuff just because you set something wrong in the UEFI.

My 3900x and Strix-E board boots fast, definitely faster and more reliable booting and shutting down vs my outgoing 7820x. That said, the 7820x was running a MSI Carbon, and that thing while it worked was often flaky. That's why I avoided the MSI/Giga boards this time around.

how is the speed in games compared to the 7820?

my msi board takes frvr to cold boot.

I haven't done that testing yet, just the benches. The 3900x walks all over the 7820x at 4.6ghz stock. It was slightly faster in single core and pummeled it in multi. Oh, I'm also using a different gpu than with the 7820x. That said, I'm not surprised yer MSI board takes forever to boot. My old board would not cold boot half the freaking time. Those little issues are damn annoying.

I'm fine here. I configured fast boot and get into Windows from a cold boot in next to no time.

I mean, I would expect a X570 board to work flawlessly with Ryzen 3000, which it is specifically designed to complement...lol. If I had one instead of a B450 and it didn't, I would be one seriously angry man haha.

If I had to do it again, I would skip the whole backwards compatibility thing entirely. Does it work? Yeah. Does it work as flawlessly as it would with a current gen board? Nope.

I don't really expect it to be a problem of a specific vendor. Each has their own quirks and disadvantages. Here in Western Canada I literally have no choices, being severely limited by mini-ITX and then again by simply being in Canada. There was literally one reasonably priced B450 choice, and literally one X570 choice.

Yea, that's the board, running the latest 1005 bios. Yea, I'm using the TridentZ's I had on Intel. I had no problems with the ram, plugged them in and enabled docp. I did set cpu to use offset voltage. All said, it was an easy build to put together. It's feel pretty mature, not like the hiccups of a new setup.

I just ran my @4.7 7820x to compare... (I have the upgrade to 3900x itch):

https://www.3dmark.com/3dm/38616996?

im using 3733 @ c16 Team Tforce sticks so that's why the CPU score is a bit higher.

I think i will wait for zen2+ to upgrade... I kind of hope that Cascade lake X pushes prices down even lower (but im doubting it).

Then you'll wait forever, as there is no Zen 2+, the next core from AMD is Zen 3.

Not supposed to be.
The one after that will be though, as by then, we should be moving to DDR5.

This is my first AMD system since phenom. I am still learning about modern AMD cpu's. I was watching ryzen master while overclocking, and I noticed that no matter which workload I try my EDC only goes to 90% max. I changed the cpu load line calibration from the default level 5 to level 1. I also set the PBO scaler to 10x. EDC is now reaching a max of 97%. Max temps increased from ~70c to ~80c. Average clock speeds seem to have increased by about 100mhz and I am seeing slightly higher benchmark scores. My max clockspeed is still at most 4525mhz.

Edit: I found the settings in the bios to set the PPT, TDC, and EDC values to those defined by the motherboard manufacturer. I am now getting 33% EDC rather than 97%.

3900X outputs a lot of heat, so 80c under full load isn't bad. What I want to know is what temps the VRM sensors on your board are reporting, if your CPU is reaching 80c.

It's probably not going to reach advertised max boost clock, so take it easy on your board.

On another note, I'm not sure if AMD has worked in some form of adaptive learning (i.e. like that which you might find in a transmission nowadays) into the Ryzen 3000 logic because the 3700X seems to be idling much better now. ~40c idle with most of the cores in sleep like they should be, and the few active ones clocked low, Vcore comes down to 0.9-1.0V according to Ryzen Master and CPU-Z.

The upgrade to 3900x is not really for gaming or benching for me. I'm encoding something 24/7, plex server, streaming media to the house, whilst using it as my daily rig/gaming. In the latter regard, this chip is a huge improvement. I'd run out of oomph on the 7820x even at 4.6-4.8ghz.

My motherboard appears to only report southbridge temps, not vrm temps. My motherboard has a crappy vrm heatsink too. I put a 40mm fan on it so that the vrm heatsink will get some direct airflow.

Does any 3900x owner actually reach the max boost clock speed?
