Micron f-die and how well they OC

[KsushaTeaKisa]

I got this 2*8gb ADATA XPG SPECTRIX D50 RGB (DDR4, 3200 16-20-20) but can't find information about Micron f-die. In Ryzen DRAM Calculator I also can't choose Micron f-die. What is it and how well they OC?

 

[ThrashZone]

Hi,
Seeing typical c16 hynix/ micron timings are 16-18-18-38
I'd say the ones you have aren't all that likely to oc well seeing how loose they are says they are LOW bins so hope you didn't pay much for them
On amd 5k series they might be better than intel because amd does like loose timings but let us know.

Hi, ThrashZone. Thanks for your reply!
It was one of the best cheap options in my country.
I actually like this kit, it fits the white build well and also has good reviews in the local store.
But I wondered why there is no information about Micron f-die? I'm not sure if I'll be overclock it, though I've tried this on a 3600MHz and it was just as stable as the factory XMP 3200.
BTW I use this kit with Ryzen 5 5500.

Hi,
AMD won't mind the stuff just raise the frequency until gains start to drop or instability starts and that's good to go

What timings/settings can you recommend me for 3600MHz? I have little experience with overclocking RAM

Did you mean ZenTimings? I will try it

As Thrashzone suggested the timings on those DDR sticks are awful.

Welcome to the Micron horrible default timings club.

By any chance could you post a screenshot of ZenTimings for your system?

Yes, sure.

I don’t even know what timings I can expect for 3200 or 3600 frequencies if I overclock. I have very little experience with overclocking.

 

[Chomiq]

Yes, sure.

For some reading you might want to take a look at these

• https://www.techpowerup.com/review/amd-ryzen-memory-tweaking-overclocking-guide/
• https://github.com/integralfx/MemTestHelper/blob/oc-guide/DDR4 OC Guide.md

If you really want to OC your RAM the best thing you can do is find examples of overclocks with your kit or people who are familiar with overclocking your kit or with it's IC's. That will help give you a good idea what you can do without having to waste a lot of time testing different settings.

I tend to go for the quick and easy RAM overclocks because testing and validation takes a lot of time, and I'd rather be doing something else, so I will just suggest an approach to help get you started and try to first see how easy or difficult it may be to simply bump up your frequency before you trim your timings. Perhaps someone experienced with Micron can jump into the thread and give you better advice. My Micron experience is limited to a few ECC kits with a lot of difficulty getting anything stable over DDR4-3200 but trimming timings has been rather easy with a bump in DRAM voltage. For example the horrible example I posted with my current kit can actually be reconfigured to be more like a normal CL16 kit.

prep

• Make a bootable usb of passmark memtest86 (the free one should be fine)
• Save your current UEFI/BIOS to a profile called "mydefault"
  • This way you can reload your original UEFI/BIOS settings anytime to use your PC until you are done with RAM OC
• Load UEFI/BIOS defaults
• Remove or disable any CPU or RAM overclocking in UEFI/BIOS
• Make sure your memory options are set to AUTO (not XMP or DOCP)
• Set your DRAM voltage to your RAM's XMP preference or 1.35v
• Set your SOC voltage to 1.1v
• Set your DRAM Frequency to your RAM's XMP preference DDR4-3200
• Disable your boot options that point to your disk (you do not want to boot to your OS with unstable memory)
• Save your changes to a new profile in UEFI/BIOS called "baseline"
• Save UEFI/BIOS changes
• Insert your memetest86 usb

action

1. Reboot
2. Enter UEFI/BIOS instead of booting from your storage when your pc restarts
3. Increase your DRAM frequency up a notch.
4. Save UEFI/BIOS changes
5. Reboot
6. Boot off the USB and let memtest86 complete 1 pass
7. Reboot
8. Enter UEFI/BIOS instead of booting from your storage when your pc restarts
9. if no errors then
   1. Save UEFI/BIOS changes to a profile "lastsuccess"
   2. Rinse and repeat steps 3 to 8 until memtest86 starts reporting errors

Unfortunately I have never come across any Micron f-Die ICs and google seems to know very little about them. Can't even find any reviews

3200 16-20-20-20 may not be a good bin for overclocking no idea how something like that would react to increased voltages.

Micron Rev.E and B seems to overclock really well. This is my current daily DR setup with some Micron Rev.E 16GB DR ICs..

Can easily push this to +4000MT. Sadly not sure if f-die can OC like this.

Thanks for the answer! I tried using frequency 3600 with 1.35v and it was as stable as XMP.

I don't know if these are good timings for the 3600. I hope these are not terrible timings for 3600?
What other safe timings and voltages can I use for the 3600 or maybe for... 3800?

Thank you for posting your example. A lot of your settings helped me unlock my Nemix 64GB kit to successfully post and boot to DDR4-3600.
I had struggled with this kit for awhile, first trying to get 128GB of it to work (now abandoned effort), then trying to get some better frequency out of it at 64GB.
I was pretty sure my kit was an E-die kit looking up the chip D9ZFV on Microns site.
Here is where I landed, still a lot of testing and tweaking to do.

( I landed my DRAM voltage at 1.38v for now )

One question I had was how are your DRAM temps at idle and under load at 1.45v?

These dimms dont have temps sensor but Micron DIMMS are less sensitive to overheating issues in most cases.
I can run 3933 CL15 @ 1.48V for hours no overheating issues and ambient temps here are close to 40 degress Celius or 104F. Even 1.5 VDIMM gives me no issues with overheating.

Try running a memory stability test. Something like TestMEM5 or similar software like in my above post to make sure your OC is stable and you are not getting data corruption.

Here is a link and a guide on how to test memory stability.

Some thoughts I had for your journey.

• Like The King suggested - stability testing.
  • Memtest86 won't cut it alone you need do other kinds of tests. I like to use it because it's quick and if it makes it through 1 pass I'm less likely to trash my OS when booting for tests.
  • I like to use OCCT for 1hr and also it heats up the ram so I can tell if I might run into a temperature stability problem.
  • The downside of RAM overclocking is as you are changing things, you need to redo stability testing at some point, and this takes time depending on how disciplined you want to step and test your changes.
    • >>> Also if you need to update your UEFI/BIOS you need to redo stability testing. <<< I can't tell you how many times AGESA updates have destroyed my overclock stability.
  • If your ram is unstable it can trash your Operating System. Swapping out a disk for OS that is disposable for RAM testing can save you from trashing your daily driver where you might have already put in a lot of time to setup.
  • Your system may not crash so check Windows Event Viewer for WHEA errors for warning signs the overclock might be too aggressive or needs more tweaking for stability.
• Did you try to scale your frequency past DDR4-3600 yet? It might be good to know what your easy upper limit is.
  • If you can get your DRAM frequency aligned with the highest supported FCLK (infinity fabric aka IF) your CPU supports that's a pretty optimal configuration.
  • I think one way to test IF limits is to put your RAM back to default frequency and simply bump up the IF until it becomes unstable or your pc fails to post.
  • For example I already know my CPU on my main rig lost the silicon lottery and can't or won't do 1900 infinity fabric (sad face) so my practical RAM OC experience pretty much stops before reaching DDR4-3800 on that CPU provided I have a ram kit and motherboard that is even capable of getting near that speed.
• When walking the frequency up once it becomes unstable one might try to give it more DRAM voltage however without more knowledge on how f-die reacts to DRAM voltage it could get risky. DRAM at 1.35v is pretty common across the board so it's fairly safe to start with.

I use 1usmus_v3 profile in TM5. The gold standard is 25 cycles. The more RAM you have the longer the test can take.

For 16GB the test should take +/- 1 hour 30 mins

I did a test in TestMEM5 (1usmus_v3 profile), there were no errors. I additionally did an hour test in OCCT, result was same.

Well nice, that was an easy overclock.
From ZenTimings what do your memory settings look like now?
Perhaps paste them here side by side for comparison?
Be sure to save your overclock settings in a profile in your UEFI/BIOS.
Also do a comparison of your memory performance before and after your overclock. I think AIDA64 had a trial or free edition?

Without trimming your timings after bumping up the frequency it's possible to have worse performance making the frequency overclock not worth the effort.

Before I knew about any guides with AM4 w/ DDR4 overclocking I made a little cheat sheet to visualize the stepping which I use as a guide when increasing frequency and not letting UEFI/BIOS auto select the values. The theory was while scaling frequency if you keep the primary timings (tCL, tRCD, tRP, tRAS, tRC, tCWL, and tRFC) in nanoseconds consistent the greater likely hood you will be able to successfully post and boot at the higher frequency than if you just let the UEFI/BIOS go AUTO and choose something that might be nonsense. The secondary and tertiary timings don't scale this way so it's not as useful for those.

The point of the chart is you should be able to compare your before and after timings with ZenTimings and realign in your AUTO configured UEFI/BIOS settings by mapping your CL values as close as possible to your original timings by understanding what those timings were in nanoseconds. Does this make sense? For example CL16@DDR4-3200 = CL18@DDR4-3600

In this way you can save yourself some time and reset tCL, tRCD, tRP, tRAS, tRC, tCWL, and tRFC all at once manually then retest and validate the overclock isn't producing errors. If you end up throwing errors then you can loosen the timings in reverse order to see which one is giving you trouble. If you don't get errors then great. You can choose to further try and improve timings. This is just how I happen to do it to get a quick overclock working there maybe better ways.

For example here is a visualization of my progress trying to OC my current ram kit now that I was able to finally unlock DDR4-3600 with my kit.
You can see the starting values on the left and the OC values on the right.
In this case I'm trying to improve performance in nanoseconds after increasing the frequency.
The tRDCRD value looks wonky because if the of Micron IC in my ram kit.

Sorry for the super late reply.
I bought exactly the same kit of RAM, and I got similar micron f-die chips, now my computer has 32GB (8GB * 4)
Now I use a XMP 3200, but as soon as I have time I'll change it to 3600 and do all the tests again.

By the way, when my PC got 4 RAM slots, my performance increased in some games and in Cinebench. I hope now because of 4 slots I will not have problems with overclock.

Hi @KsushaTeaKisa I recently bought a 2x8GB kit of SPECTRIX D50 3200MHz (white colour 16-20-20) on a sale. I was expecting it to be Micron E die but it actually was Micron F die just like yours (maybe since 2022 they started using F die since my friend bought this in 2021 and has E die - mine's manufacturing date is Week 13 of 2023). I bought this one because my friend told Micron E is good in terms of OC and he was able to run 3600MHz stable at 1.4V with stock XMP (16-20-20-38) timings.

Could you please share your final timings/volts for 3600MHz - I will do my tweaking around them as it will give me a head start.

Thanks
