Crucial = Micron, there's a Micron Memory factory located near my workplace here in Penang mainland. Their SSD factory is located at Batu Kawan, which is also not far from there.

Not bad for 4 sticks to run at 3600 on old gen, in your case 1700 and X370. Very nice. Did you run any stress test to confirm stability?

The Crazy Record appears to have one error there so not really stable. From what I heard Micron E has better thermal tolerance compared to Samsung B-die. The latter prefers cooler condition not more than 42C to achieve OC stability. Only downside on Micron E is that tRCD cannot be tightened as much as B-die.

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.

MCO Day3 benching with 3700X and Micron-E (D9VPP).
Using 1usmus' DRAM Calculator 3800 Fast profile for primaries and Safe profile for subtimings.
Full Fast profile thrown me an HCl error at 100-150%, that's why Safe profile being used for the subs.
I know it's not efficient but I'm definitely working on it.

Update: Today MCO Day4, I managed to tighten the subtimings a bit. tWTRS=5, tWR=18, both SCL=5 are pretty much hitting the wall. So far 1.45v is compulsory otherwise HCl will throw an error as soon as 150%.


Update 2: tWRWRSD & tWRWRDD reduced from 7 to 6, resulting in higher read bw 55k.


Update 3: Increasing the ClkDrvStren to 120 has allowed me to reduce primary timings to 16-19-14-14-34, as well as both SCL and tRDRD down to 4, but a slight voltage bump of 1.46v is required. AIDA64 scores are now improved a bit.


Update 4: GDM off is free of error as well.

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

Thanks for the tips bro.
The bold part already tried earlier, not possible at 1.45-1.46v.
Maybe need to pump more juices to cross the HCl 150%.

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

Quick test 3800 CL16 @ 1.35v.
Manual primaries, subtimings auto, manual terminal block 34.3, off, off, RZQ/5 (<= auto will give error at HCl 120%).


XMP @ 4000 CL18-19-19-39-1T @ 1.35v

My 3700X at stock clocks auto voltage registers at ~74C Tdie even under high-end custom loop. This is just a single loop of CB R20 test, let alone long-term stability tests such as p95, AIDA64, OCCT etc. Let's see how it goes with manual voltage later. I need that der8auer custom bracket badly.




Can't imagine how did others get with AIO or even air cooling.

Moving to my regular B-die now, it was a 5-minute job because I just reused most of the settings from my previous run with 3600X. Now 1:1 is possible with this new 3700X.

1.48v OK for long usage? I usually max at 1.4

Not really sure but I believe up to 1.50v should be fine, provided it's properly cooled with fan/water block.
So far there are two kits rated at 1.50v XMP:

https://www.corsair.com/us/en/Categories/Pr...16GX4M2Z5000C18

CL14-15-14-28-1T is also possible at the same voltage

Will continue tightening the subs

Update 2/4/20: Tried the other B-dies including my older TridentZ RGB 4266C19, D80 3600C17, NightHawk 3600C18, none of them is able to achieve stability using the above settings. Can't even stable at 14-16-16 at 1.50v.

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.

Well done bro.
At least your copy speed is always above mine, in which I don't know why haha.

I believe there are still some other locals who are into RAM OC just that LYN is not a medium of sharing their OC results. Hey this morning I met one local OC enthusiast in shopee, who has already delidded his 3800X chip, benching quite a number of B-die, E-die RAMs and resell them.

I used to write reviews for OCDrift.com website and most recently in LYN review section, no youtube though. It was fun but now no more due to time constraint. Btw, don't bother reading as those are noob reviews.

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.

Ahh my bad, I swear I didn't notice that your E-die is DR haha.. mah eyes

or better don't delid it cos not worth the effort and time.
Definitely need to try that der8auer offset bracket, which he claims to offer 5-10c improvement on the temps.
Too bad Caseking doesn't ship to Malaysia.

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.

I think as long as micro-fins of our waterblock cover the whole chiplets we should be fine.
On the other hand, I need to spend time dedusting the rads, it's been a while.. haha

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.

Continue benching with B-die
As mentioned earlier, my older TridentZ RGB 4266C19 is weaker than the newer kit.
Only able to settle at 3800 CL16 instead of C14.

Mixing strong and weaker sticks, my copy speed is now 55k after messing around with some settings...
