This is probably the best I can do after trying for months during MCO.

i tighten up the trc to 28 and able to boot. Is it no harm using the overclock profile and change timing ?

It's totally safe unless you put too much voltage. Personally I don't like to go beyond 1.4V although up to 1.45V should be fine for b-die. But do check stability of your overclock with good ram test software.

You're running all core overclock at 1.42V? Many people in other forum say anything more than 1.35V will cause CPU degradation. Some even say 1.30V . So far I only dare to push my 3700x up to 1.31V only.

But your RAM are crazy fast with super low latency . B-dies are still king!

to me manual oc is dead (for 24/7) setup. get d vrm & cpu cooled as much as u can, then let d pbo does its job.

so one only left with ram oc to play with. 3800 @ 1:1 with tightest timing & vdimm which u can tolerate is d way to go imo.

I don't dare push 1.42V for all core and I still need my single threaded performance. This is a gaming rig. I'm running it on PBO +200Mhz with PPT 300, TDC 230, EDC 230 .

same setting here bro. BZ recommended setup.

if only can do like +400MHz would be damn good... lol...

Only binned Samsung B-die is good. I have been bitten by junk B-die so many times.


I got this kits. I confirm in Thaiphoon burner is B-die but can do 3800Mhz CL18 only


Thaiphoon burner also confirmed this SODIMM 2666Mhz CL15 as Samsung B-die but this is the most junk bin of it.

So 1 must not blindly aim for Samsung B-die. There are junk B-die too . I learnt my lesson.

this is my take on the new gen Ryzen cpu's as well.

cool it as much as possible, let it fly on its own. get a very good set of rams and go as tight timings as possible.

I find even PBO is very inefficient. Setting it on will increase power consumption from 65w to over 95w with very little gain in performance. So i'm still running at stock without PBO

That's why I didn't want to gamble with Samsung B-die and rather went for cheaper Micron Rev.E.

binned b die are hard to get & pricey, cant blame ppl tryin to find gem among d stones bro. those really binned bdie (mostly CL14 rated @ 3200 > 3600) dont worth d price we pay for just to run 24/7 setup. i have a pair of bdie (ven pro rgb 3600 cl18) too but i really not comfortable to run high frequency @ tight timing like u. d kiasi-ness is stronk in me...

C&Q still work with PBO disabled? i'd say PBO worth d extra watts compared to running slight perma oc though, so it's like best of both worlds with some compromise. for those dont feel comfortable runnig their ram with high voltages for 24/7, micron e is better choice (while being laxer timing wise compared to samsung bdie). bdie is capable of okayish voltage @ 3800 too if one dont really mind d non CL14 setup. mine runs perfectly fine @ 3800 CL16 with 1.36v for 24/7. when it comes to price, no doubt micron e wins hands down.

don't trust thaiphoon burner blindly. I've myself seen it more than once giving wrong info on dies.

@k!nex fine kit, haven't tested stability?
I have my doubts its really stable with this tRAS @21 with tCL and tRCDRD at 14 each.

I passed 1 hour of Realbench stress test though. So far for gaming, i never got any issues.

Depends on how you define expensive la. I found the cheapest binned B-die on shopee though. Not total junk B-die like my G-Skill Trident-Z 3600CL18. Like what @nrw said, it might be Samsung D-die too because Thaiphoon burner might read wrongly.


8GB X2 3600 17-18-18-38 1.35V


For Samsung B-die, i think 1.5V is probably the max 24/7 voltage since I have seen G-Skill sell Trident-Z DDR4-4600 CL19 23-23-43 @ 1.5 V kits. I mean they wouldn't sell this SKU if they know running at 1.5V for long term will kill the RAM. And they do have lifetime warranty to back it up.

what did the 042 code look like on your tridentz 3600c18?

I have 4 sticks of these Trident-Z.
04266X8810C
04240R8410C

Bought a week before Chinese New Year 2020.
I dont think it is a B die. It cannot go below CL18 at 3800Mhz even if i shove 1.45V to it. Put 1.5V , i cannot even POST with those 4 sticks.

last 3 digits 10 is samsung, c is c die

gotta admire your patience. I'm too lazy to boot and reboot trying out each timing. So far ryzen dram calc does fine in giving me 3800cl16 at 1.4v

Getting 65.3ns on aida latency test

But thanks for sharing. Might steal your timings for bragging rights

That answers my doubts already. Thank you very much. 3600CL18 really got lots of lousy RAM kits but that is the only thing for sale in lowyat plaza.
Want better binned RAM, have to buy from Amazon.

I am waiting for a good opportunity to sell off my Trident Z kits since i got a better kit now. RAM price still going up like that. Wait abit more can sell higher

Tbh, if you buy at local stores, just check the corsair vengeance 3600 (maybe even 3200) kits.

The version number is visible through the backside of the sealed boxing.
v4.31 would be b-dies.
