Hey guys

I need some help getting this setup to its optimum, I would like to tighten the RAM timings as well as get the CPU to a solid and permanent OC of around 4.2ghz under full load.

CPU is running under a Kraken X63 so cooling should be sufficient. PSU is a Corsair RM850

What I have done so far is set the CPU voltage at 1.32v but under load it drops to 1.248 and the CPU throttles. I have also enabled AMD's version of XMP

Any help will be greatly appreciated, I haven't had an AMD system since my XP3200

I there, my 3950X is running at 4.2ghz using 1.1875vcore which drops to about 1.169vcore under full load. Try your 4.2ghz overclock using 1.2250vcore and see if it holds. I found that leaving LLC on AUTO actually performed better, less vdroop under full load. Not sure what your LLC is set at. If it is not set then you can try the middle to highest setting to see if any change under vdroop. I do not use any onboard overclocking, I clock the processor manually in the bios for bets results.

Please bare in mind I am a complete n00b with AMD so I would need exact settings. Like for instance AMD doesn't use XMP it's called DOCP.

So what exactly must I change to get ram to say 16-16-16-36 and CPU to 4.2 all-core?

Does the speed drop?

I got mine at 4.250 GHz at 1280v all core. I dnt see any throttling. I also got LLC on auto.

DOCP should be fine for setting the memory at rated speed and timings. But if an issue, let me know.

Ram timings I really dnt know, maybe @JollyJamma. He plays around with this.

What motherboard you got? I'm also new to AMD and trying to figure out the same thing, if this system is running optimally.

Yeah, everything is auto except the voltage which I set at 1.32

No, all is OK but I would prefer to tighten the timings to 16-16-16-36 if possible.

Look Ill be honest, E-die Im not sure and 16-16-16 may not be possible.

Test in Ryzen Master, set all core to desired speed. And decrease the voltage. Test until you find a stable setting. Then apply that in the bios. Everyone I spoke to who has this chip is running it in 1.2 range.

I'm not sure about Asus boards. I'm on gigabyte. But mine has option to turn PBO off and set manual all core.

Use this to help you with that.

You can export your memory profile from Thaiphoon burner and import it into this tool.

What you can also do is download Thaiphoon Burner and run it, then go EERPOM and view the ram module. Then check firstly DIE DENSITY / COUNT which will give you the specific memory chip, secondly check ORGANIZATION which will indicate in () brackets 1 rank or 2 rank. If you have two memory dimms / modules it is most likely 2 rank or dual rank which in itself has some limitations but not too much to affect performance.

Couple things.

Timings can be very tricky if you have iffy silicon. Do you know what chips you are running? Samsung B die, E Die, Micron, Hynix etc

You also get bad quality B Die so it’s really hard to say how far you can go.

Another thing, motherboards rarely report accurate voltages and they are often fine. If the memory is stable then it’s probably just a reporting issue.

ITx boards can be tricky to overclock with because of heat.

I’ll post a RAM overclocking guide here and you should also use the Ryzen memory utility.

RAM can run as high as 1.5v but most will be happiest at 1.35-1.38.

Some ram won’t respond to any setting changes what so ever.

It’s the silicon lottery with maths so it’s hard to make recommendations without being in front of your computer and having a bash myself.

I found this video from Hardware Unboxed to be rather resourceful. It centres around memory timings for Ryzen. Maybe this can help a bit.

Great advice, thanks. Got it at 4.1ghz at 1.224v. Running Folding@Home which is hammering the CPU at 100% and temps are 88 celcius

Is that acceptable?

They are the G-Skill F4-3600C16D-32GTZNC which I believe are SK Hynix C-Die chips.

Your stock memory timings for the memory is 16-19-19-39.... If that is correct then yes it is most likely Hynix C-Die and you will be limited on the timing side. You could in the bios change the following memory timings:
First:
tRCDWR to 18
and see if it boots up - run tests and test
Secondly:
tRCDRD to 18
and see if it boots up - run tests and test
thirdly:
tRP to 18
and see if it boots up - run tests and test
lastly:
tRAS to 18
and see if it boots up - run tests and test

If all went well, drop each one more, one at a time and test to see if you good.

There after you can play with tRC dropping is about 2 at a time and test, and tRFC dropping it about 10 or so at a time and test.

Look I hope it works, but I generally check in OCN for some timings people get but I'm never able to get in any event but it gives me a good starting point.

Even when I dropped to 18 the machine wouldn't boot properly. Maybe I will try upping the mhz next

you could try the memory speed one step higher, 3666 and see if it works.

Is that acceptable?

I'll say yes based on what I got. You can go a little more if the temps stay within a acceptable range, just move in small increments until it fails during testing. But think about it you got 16c32t at 4.1ghz, amazing times we live in.

The temps are spot on also. With normal use it won't even go close to 88. I wonder if we use a full loop, if we able to push up the voltage and speed.

Amazing times indeed, I settled on 4.2 @1.224v

Seems OK for now @100% util an 91 celcius.

Download, run, add your memory’s details, hit calculate.

It’ll work out your max speed and timings.

How do I find PCB version and which version of Hynix memory it is?

How do I find PCB version and which version of Hynix memory it is?

CPU-Z as far as I know. Maybe google the serial number too.

Then check firstly DIE DENSITY / COUNT which will give you the specific memory chip, secondly check ORGANIZATION which will indicate in () brackets 1 rank or 2 rank.

Damn, i'm f#$ked.

D Die, thought it was C (B Die upgrade is needed)

2 ranks (I knew that already)

 

[VPII]

Yup 2 x 16GB is usually dual rank

 

[Juggy]

Ok, so if I had to get the best possible 3600-4000mhz 2x16GB sticks for Ryzen what would it be?
