Ryzen 3900X can't clock 1800MHz Infinity Fabric with 3600 CL14. Disappointed with Ryzen.

[hzy4]

dude according to hwinfo?? your running an R9 3900X QS .. a qualification / Engineering Sample Silicon. LOOK at TOP LEFT then look to the right of the CPUs (OPN).

Hold you horses. I dont think it is an engineering sample, mine shown the same. The HWinfo App has obsolete information as no update was released to support Ryzen 3000.

 

[biffzinker]

It's Hwinfo, my 3600 is reported as a QS

 

[sneekypeet]

I'm going to go ahead and say it. You either have a crap CPU, but I doubt that, or the RAM you are attempting to do it with is the issue (most likely)!

All I did was clear CMOS, slapped in sticks I thought should do it, set 1800 IF, 3600 RAM, and tried to post. It failed, so I dropped 1.45V to the DRAM and here is what I get, solid as a rock.

 

[hzy4]

70ns on 3600mhz CL14 seems awfully high, should be more like 65ns

Didn't tinker with anything but the main timings. also not that pressed about 5ns.

You might want to try the latest beta version then, as it has Ryzen 3000 support.

With regards to DRAM, it seems Hynix CJR is a good way to go for Ryzen, both based on my own experience and now with some third party testing.

Just to chime in.

Use membench from DRAM Calculator to validate, don't jump straight into Cinebench. It will save you some time and blackscreens/bsod's.

On my E-Die (given that it's rated at 3200) system would boot fine with OC to 3600 CL14 on Aorus Elite but would throw errors in membench. In the end it wasn't stable at 3600 CL14 or CL16, I didn't want to mess with it so I gave up and stuck to 3466 CL14. But your Elite's are rated at 3600 so I see no reason why it shouldn't work fine at CL14 with some adjustment. You could try tinkering with XMP High Freq Sup level settings.

Also make sure you don't use R-XMP and import the .html profile from the Thaiphoon Burner instead.

 

[KhakiKukhi]

I tried asking the same question earlier in the thread.

Ryzen 3900X can't clock 1800MHz Infinity Fabric with 3600 CL14. Disappointed with Ryzen.

My Ryzen 3900X that I just recently purchased can't clock to 1600MHz on Infinity Fabric. When I clock to 1600 IF with 3600 memory, testing Cinebench R20 causes my PC to black-screen and reboot. 1400 IF with memory at 3600 is stable. Memory is Ballistix Elite 3600 CL14. CPU is running with stock...

I've been saying this. 3600 CL16 with stock BIOS with only XMP enabled does not work.

I was responding to @erocker. Understood from earlier in thread that it wasn't working for you.

 

[KhakiKukhi]

I was responding to @erocker

Oh alright, I'm sorry.

I somehow doubt that a 3900X with the gear that @KhakiKukhi has can not run up to max 1900 Infinity Fabric.

Some things to try.First get proper setting for the ram and then apply enough voltage to the Ram,Soc etc.

Suggestion for Ram Download DRAM Calculator for Ryzen with Thaiphoon burner

In thaiphoon burner export your XMP profile with complete HTML Report and save delays in nanoseconds to desktop or somewhere you would remember.
Then import the XMP complete HTML Report to DRAM Calculator for Ryzen

Then in the DRAM Calculator for Ryzen pick the settings you want and try them,they are meant as a guide. Print out setting from main and advanced or write them down.

In BIOS set everything to optimized defaults and restart back in to BIOS.

In BIOS input the settings from the DRAM Calculator for Ryzen-depending on what settings you picked voltages may be different.
Disable-PBO for now,can re-enable anytime
Set DRAM voltage to 1.5v for now ,can lower later
cLDO VDDG - 0.900v Most likely your auto settings set this to high,use recommended setting from DRAM Calculator for Ryzen
cLDO VDDP - 0.950v Most likely your auto settings set this to high,use recommended setting from DRAM Calculator for Ryzen
SOC - 1.12v -Set to max from DRAM Calculator for Ryzen for now.I use higher than max on my system for stability.
DDR4-Set to 3600Mhz or whatever you picked in DRAM Calculator for Ryzen
The memory clock (mclk), the memory controller clock (uclk), and the infinity fabric clock (fclk) all need to be synced for best results.
So in BIOS set fclk-1800Mhz or half of whatever you picked in DRAM Calculator for Ryzen
So in BIOS set mclk=uclk
When set the mclk:uclk:fclk should be set to ratio1:1:1 for best results.

Give these a try without toughing anything else in your BIOs and see how it goes.

I'm gonna try this.

I didnt say 1.36 im saying volts of 1.37-1.44

Then I'll try this.


I can't find cLDO VDDG and cLDO VDDP in my Gigabyte BIOS.
The closest I've found is "CPU VDD18", "CPU VDDP", "PM_CLDO12", "PM_1VSOC", "PM_1V8".

This is the MEMbench results with stock BIOS + XMP + 1.45V DDR.
But this fails at a Cinebench R20 benchmark.

 

[TheLostSwede]

Just throwing my numbers up here for you to compare with, Cinebench runs just fine as well.

 

[KhakiKukhi]

Oh alright, I'm sorry.

Okay. I just ran mine again and got this. How does it compare?

I'm getting memory errors lol.

 

[Chomiq]

You're on stock bios? Which one is it? F1 or F3? If you're on F1 update to F3.

1. Update AGESA 1.0.0.3 ABB
2. Improve Destiny 2 gaming compatibility
3. Improve XMP DDR compatibility
4. Support AORUS Memory Boost
5. Support JEDEC DDR4 native 3200MHz memory

I'm on F3, the latest one.

 

[Chomiq]

@TheLostSwede should have a link to list of beta bioses. Worst case scenario? Ditch Elite's and get a different set of ram.

I'm very new in this DIY PC stuff and I'd like to ask: is the RAM or the CPU to blame? Why is it to blame?
From a n00b's perspective, I thought the IF might be the problem.

For a different set of RAM, I have my eye on a nice set of Trident Z Neo at 3600. Unfortunately, they're CL18 sticks.

 

[TheLostSwede]

F3 should be the final release of F3, so the beta UEFI isn't likely to help until AGESA 1.0.0.4 comes out. From what my mate at Gigabyte told me, it should be out at some point this week.
You can find beta UEFI's for Gigabyte boards here otherwise.

You're not running 1:1 either, not with latencies above 80.

It would seem Intel and AMD memory controllers behave very differently in terms of what latencies memory can run at.
Have a look at this as an example (using Google translate, unless you read Romanian).
Also, Hynix CJR DRAM seems to work really well with Ryzen 3000 CPUs.

Why not try your current RAM at a higher cas latency?

Memory errors:
- Timings are too tight, need to loosen them up a bit
- The voltage is insufficient for your particular chips (you did not win the silicon lottery)
- Motherboard quality not great, there are inconsistencies in traces resulting in instability of signals

In any case, you must do something about it, as memory errors result in corrupting data (not just crashes), and in some cases completely losing it (for example, it might corrupt an archive/backup to the point where you can't unpack it anymore). Very unsafe to use the system with data errors !

After it seems it's running OK (after several retries) in MemBench, do an overnight test in MemTest 86+, to see if it's actually stable/no errors.

MemTest86 - Official Site of the x86 Memory Testing Tool

MemTest86 is the original self booting memory testing software for x86 and ARM computers. Supporting both BIOS and UEFI, with options to boot from USB.

www.memtest86.com

It took me over 2 weeks of fine tuning timings until I found a set that works 100% stable on my computer (Tighter than XMP timings)

Currently at DDR4-3400 CL14-18-14-32-56-and-a-whole-bunch-of-other-numbers-which-do-matter-for-stability-but-less-for-performance.

Note that I'm using CL14 on a memory designed for CL16...

This is at 1.41v, if only 0.05 less (1.405) it throws the occasional error in MemTest86 (Windows and games work perfectly fine, but not risking it, since my computer is also used for work)

Perhaps this has been brought up already, but where can you go to find the manufacturer of the underlying memory ICs? I presume the manufacturers specs will have them somewhere but is there a memory database somewhere out there?

I've been saying this. 3600 CL16 with stock BIOS with only XMP enabled does not work.

Think about that statement.

AMD's processor wont work with your memory's Intel memory profile?

It's not impossible your chip might yet have that one thing you have not tried but it's also possible it's not possible, some chips won't do it mine wouldn't until last night.
I upgraded my crosshair hero VII bios to 2703, I lost loads of bios functionality , mostly in the advanced tweak section which is near empty now(they seriously narrowed user tweaks).
Thing boots at 3600 C16 ,seam's stable, that bios had ageesa p1.0.0.3 ABB.

Perhaps waiting is key to fixing it via bios update.

Ps I have gone through three sets of memory in total really two sets died early , i didnt even use ryzen calc , but last memory swap i made sure i got Bdie ,good quality not low bin as i had got before, so it is good memory.
but i used a stilt profile and auto set its fine, the last time his timings worked too ,even clocked higher then he had, ill be trying for more.

pps Is memory and finity clocking the new consumer clocking?

 

[KhakiKukhi]

Okay, right now, I'm running 3600 CL16 with IF at 1767.
In membench, I'm getting 80+ latency.
I've settled on:

1. Enabled XMP 3600 CL16
2. DRAM voltage to 1.440V
3. IF at 1767

 

[Cowboystrekk]

How is your latency with ram at 3533cl16 instead? It will probably improve performance
