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

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  sweat.gif . So far I only dare to push my 3700x up to 1.31V only.

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

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 .

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

» Click to show Spoiler - click again to hide... «

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.

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.

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...  tongue.gif

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.

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.

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

Share my 3700x OC and benchmark results here for reference:

Purchased in May 2020. Sorry as I forgot to snap a photo of the manufacturing date which can be identified on the CPU heat spreader.  More recent CPUs perform better in overclocking.

Your 3700X is amazing. I cant even push mine on static overclock to be stable at all core 4.3Ghz at 1.35V vcore.

If you have Samsung B die kit. Watch your memory temps. Once it goes above 50C , memtest will spew errors everywhere.
If you have the guts , then increase vdimm to 1.5V. push for cl14 and dont use 2T CR. In bios , CR put Auto and enable Gear Down Mode.

Vsoc put 1.1V enough, i know that once you hit 1.15V and above here , it can start to spew errors .
Vddg iod 1.05V.

Read up 🤣 thats what he was asked to set. So he done that.
You can try to raise tRFC to 280 n see if it posts.
You can use the safe boot button btw, no need to clear cmos.

Edit: @k!nex VDDG to 1.05V?  hmm.gif poor IMC.
for B-Dies just keep between 0.95V & 1V. Try what suits your chip.
*
Vddg iod 1.05V is by default on my motherboard if i put FCLK at 1900Mhz. I have read that this voltage safe setting is not to go over 1.1V and it needs to be at least 40mV below Vsoc.

Actually your current setting also good enough. 16-15-15 @3800Mhz is ok la. Sometimes its your luck also

This is confirm Samsung B die. But this one no RGB. Your rig so colourful. Might as well go buy G-Skill higher binned ones.
I have 2 sticks on these. However, if you run 4 sticks, dunno what will happen.

If I want AVX load stable, then i got the above timings at best. TRFC can probably go lower. I haven't have time to try.
If I want purely gaming load stable, I can drop my TRCD to 14.
However, I run my voltage abit higher than normal ppl.

actually my neo which i bought is 16-16-16-36 1.35v. Isn’t it confirm b-die or i am wrong ? i actually turn off all lightning while i use. i haven’t install the icue becoz icue seems lower down benchmark score sad.gif

16-16-16-36 is B die. If its a Hynix CJR or Micron Rev E, it will be 16-19-19 like that. And If you dont have a B die, your TRFC cannot do ~300 for sure at 3600Mhz

Anyone know what chips is used inside the latest G-Skill TridentZ Royal?
I'm thinking of buying the gold C18 version as per the link below

95% certain is Samsung C die. Another 5% possible Hynix CJR. Because I have 1 set of Trident-Z RGB and 1 set of Trident-Z Neo 3600Mhz CL18-22-22-42 1.35V. Both of them also Samsung C die. Trident-Z Royal seems to have the same PCB as the other Trident-Z series except different heatsink and the lighting effects.

Whats the best that you manage to squeeze out from your samsung c die kits? Especially the trident z neo 3600 cl18.

3800Mhz 18-22-22 at 1.38V. However on my X570 Aorus Master , it cannot do this clockspeed at 4 sticks using F11 Bios. After update to F12G , i can do all 4 sticks 3800 CL18 stable but looser TRAS

after a full day testing 3800 is not stable. system doesnt crash totally, but i get stuttering. my discord sound gets disoriented and my game will flicker.

back to 3733 now.

Put a little higher voltage. I manage to get mine 3800Mhz stable at 1.38Vdimm.
See stable or or not. Not stable only go mess with VSOC and VDDG IOD

have yet to play with any highly binned samsung c die but at that timing it's very close to CJR (which can do slightly tighter timing i supposed). I'd say get it totally stable 1st, then only tighten d timing from there.  smile.gif
*
Hynix CJR is better than than Samsung C die for sure. At least it does scale well with voltage for CJR at 3800Mhz. Samsung C die absolutely hates voltage above 1.4V .
For CJR, it is easily doable at 16-19-19 or 16-20-20 at 3800Mhz 1.42 ~ 1.45Vdimm. TRFC below 500

C die is so damn hard to get it to tCL 16 stable at 3800Mhz. I gave up. I got stuck at CL18 no matter how I do. At least for my 8GBX2 3600Mhz CL18 G-Skill kit.
