OCing GSkill Trident Z RGB 3200mhz CL14 to 3600mhz CL14 1.45v with Asus X570 C8H


Attached thumbnail(s)

Very2 nice score there bro... 3900x really a must if budget allowed. Any luck on 4k ram? 👍

Didn't try further, i felt bumping the voltage to 1.45v already considered quite high, average temp at 41~42 degree celsius. Not dare to go further

So, RAM write bandwidth of 3900X is 50k MB/s vs 3600 29k MB/s. Interesting...

my bad bro... didint notice they're 32GB paur... fantastic MHz & timing!!!

it's d single chiplet vs dual chiplet thingy bro... so Ryzen 3K only starts @ 3900X...

suicide run again...

Nice clockin' bro, if possible try to improve the BW efficiency cos now seems slower than your 3600 CL16 run previously.

forgot to change d fclk bro (was using 1866 just now instead of 2100), but i think very high frequency + rather tight timing is needed to beat 1:1 result... this is already the fast profile usin dram calculator @ 4200, doubt i dare to go extreme profile w/o killin d loaned ram...

Make sense, looks like 3800 CL14 is a thing now for Ryzen.
Anything above will just kill efficiency.

Btw, a 3600/3600X @ 4.2GHz with 60ish ns latency should be able to match 8700K @ 5.0GHz (~1650cb) in CB R15. Not sure if your cooling is still able to handle it.

yup, that's what i noticed too.. 3800 with some luck still doable though 3733 is d max recommended for 1:1... i give up on all core oc already bro, my chip is a lemon - even @ 3.9ghz full fledge 6c need a whopping 1.45v, small fft fails within a mins (for all 12 threads)...

1st sub 65ns attempt, slightly better than ryzen 2k, bdie really helped alot i guess...

bdie is heading back to d owner so this is pretty much d last attempt on basic stability test (minus d efficiency as usual... )

DDR4-4500+ is seriously not bad for a kit that's rated at 3466.
In plan to try Micron E-die?
I heard it might be as good as or even better than B-die in terms of thermal tolerance.
For record, B-die will fly higher if you are able to keep the temp below 42C.

Teamgroup @ DDR4-5000 CL18 with ASRock X570 AQUA

Thats what i think also bro, really not bad but d efficiency realy not there so its really just for d sake of figures only.

No plan to go micron e die as of now bro... Infact am decommissioning d rig liao. I see what i wanted to see already.

Thanks for d tips on d temp bro, will ask d owner aka kemal to take note of this.

Hi guys. I tried tightening my RAM timing using the DRAM calculator and it seems to work. 3200 from CL16 to CL14 and all those other timings. Tried testing the RAM and no error. But if i try to on the PC (cold boot) it won't start and after a few resets, it will just revert the RAM to 2400. Any idea why?

isnt that board like RM4k+

RAM issue with cold booting, doubt that your RAM OC is stable.
With what software did you test the stability of your RAM OC?
Mind to share any screenshot of the run?
Perhaps you need to play more with memory settings such as disabling GearDown, adjusting procODT etc.

ASRock X570 AQUA - RM 4150

I have just built a rig with Ryzen 5 3600 with B450 Strix-F. On latest bios 2605 (Aegesa 1003 ab). All core boost clock (PBO + auto overclocking) is only 3950Mhz during CPU-Z stress test and Aida64 stability test. single core boost also never goes beyond 4100Mhz. However i can manual overclock to all core boost clock of 4200MHz with voltage of 1.4V, Aida64 stable for 30min.

I am using 360mm AIO and my CPU temp is good. Max load while on PBO + auto overclocking was only 72C. Hence the PBO is definitely not limited by the temp.

Any sifu here can confirm whether PBO is broken for B450 chipset with latest microcode?
