finally had some time to finalize my ram oc

First system: 3900x with 4x16GB E-Dies

Second system: 3700x with 4x8GB B-Dies


Tried some ccd/ccx oc with the 3900x but eventually reverted to default with some bios tweaks only (for gaming and this membench its running 128w,85a,130a (ppt,tdc,edc) e.g. as that one doesn't really cause fps drops.) pretty much same for the 3700x just that that ones running on the default 65w settings.

😂 not really into these APUs but I remember that starting with AGESA 1006 most board manufacturers enabled OC and even allowed pci lane unlocking.
So ya, you're either one year late or you just updated the boards bios to a version including an AGESA that enabled it. Or maybe you just changed boards.

So ya, go for 4Ghz and 3200 👍

Yep, E-Dies are kind of the go to if you don't want to spend on B-Dies.
They are not selling in Malaysia, maybe their updated model will be .... however that one got quite a price hike.

I have (had) 6 E-Die kits of which all were made in Muar.

The values in the DRAM calc are not really good for those E-Dies btw.
Would be surprised if your 3600 setting is stable first shot.

good E-Die kit, nicely done.

looking at it I'd have the following suggestions.
drop tCWL to cas-1 or 2 (14 or 15)

others worth trying
tWTRS 4
tWTRL 6
tRRDL 4
tRCDWR 9
tWRWRDD 5
tRDRDDD 3

usually not scaling that much with voltage. doubt it.
anyways getting this stable with gdm off (especially in just a few days) is quite an achievement already!

never managed to get that stable myself ... and didn't really want to put so many more days into it.
oh well. 0.3-0.5ns latency 'only'

quite amazed to not see CADs 24-24-24-24 btw.
have never thought of trying anything close to 120 myself.
maybe I'll give that a try during the next few days.
testing with 2x16 DR is a bit more time consuming than your SR kit

Guess I'll share my set ups too then.

1) X370 C6H | 4x8GB Kingston 4000C19 Kits | 3666 14-15-14-28-1T | 1.45V (downgraded 3733 setting due to IMC)



2) X470 C7H | 2x16GB Micron Ballistix Sport LT 3000C15 Kit | 3800 16-19-16-38-1T | 1.44V


At last I managed to preserve the latency.

Actually it is a pity that so few ppl in here seem to be into RAM OC. Especially for Ryzen it is def. worth it.
Even more of a pity that those E-Dies are not for sale locally.

Btw @owikh84, are you doing reviews on websites or youtube?

Edit: E-Die configuration added.

Copy speed cuz of DR vs SR. You just can't change that.

Oh I see.
Too bad those guys don't write here. Could easily influence others to start with a bit of it as well.
And delidding AM4, wow. Too bad there's no direct is easily feasible cuz of the higher socket.

OC bracket ... if you are so keen I can help you to get you one of these. Will just take some time.

But frankly speaking, I think with a good waterblock it is 1-3°K at most. For consistent loads less.
There have been a few good reviewers and manufacturers (Igor (Igorslab), Noctua, Aquacomputer.de) doing research on this already.
Their conclusion was all the same... it is simply not worth it.

Edit: Aquacomputer.de stated with this technique you can achieve an improvement of 1.3-1.5°K per 100W TDP.
I added a photo of their new mounting. These are numbers I would trust. Their products and testing are superb.

Ya, the better quality the fins and the greater the area cooled on the heatspreader the lesser any potential benefit from these mods.
I doubt those brackets would be much use to you, or me. And what are 1.3-1.5°K anyways, nothing.
I run Zen2 mostly on stock with some minor bios modifications such as enabling cppc. I do not even bother to turn PBO on as it's just a waste of power.

Maybe for some AIO's it will be beneficial, maybe those with small round contact area on the heat spreader.

But before I'd spend 30 Euros (+postage) to upgrade my shitty AIO with these brackets, I'd much rather use exactly this money to buy a better AIO to start with.
Benefits will be far greater.

Fixed voltage is not a good idea actually.
Rather work with offsets.

Keep it synced. Max so far is 1900. The Apus next month will be able to do at least 2000.

yeah quite a bad one but that's the lottery ... doubt you cou get a successful warranty claim on it.
just run it stock and wait for zen3

Zen2 you can let the cores go to sleep, hardly any performance loss.
And ooc. you never disabled EEC? For my C6H Auto was Enabled, can cause issues at boot.

Oh @crazyfatt, try other voltage offsets (-0.025V till -0.15V) and compare performance/temp.

Single core is pretty low.
MC also not more than stock with a stock 3950x (always around 9150-9250)

Try to test with this:
- PBO Off
- No VCore Offset
Then check my power plan thread and change the bios settings from the spoiler there.

Then test once with your stock power plan and once with the one I was sharing and let us know results here



What owikh84 posted under 5) "Disable C-state:"
Disabling this would prevent cores from going to sleep but I do not think this is necessary.
(You already disabled it) enable it as per above.

Advanced AMD CBS and sub menus probably

"The last dance" with Zen2 at RAM OC as I've got a 'new' 2x8GB Micron E-Die Kit.

3800Mhz | DRAM 1.40V | VSoC 1.05V | VDDG 0.975V | ProcODT 32Ω | RTT's 0-0-5

Micron E-Die quite easy to OC because there is not much variance between kits. (Unlike B-Dies)
You've done it once and you kinda know which values to tweak and try.

For B-Dies the Ryzen DRAM Calculator is quite good. Just save your RAM's profile with Thaiphoon Burner, import to the Calc n try the values it spits out.

Even for an average bin you should be able to get cl16 at 3600MHz. If above average cl14 also no issue.
If I was you I'd go for 3733 or 3800 C16 whichever your CPU supports for the FCLK (Infinity Fabric).

Better luck next time then.
What board are you using? And do you just adjust primaries?

Ya with some board that does't work well though. You can just put 300-230-230

the thing is once you set edc to 1 the workload current detection is disabled for all I know. this results in a voltage bump in some instances.

once you run high (synthetic) workloads (avx etc.) on a regular basis this might degrade your chip.

better use something where your voltage stays within specifications.
