my bad bro, really lost touch liao nowadays (exuse of being plain lazy )...

AMD always favor tight timing @ decent freq. as pointed out by bro owi, B-Die (Samsung) will win single-handedly when it comes to mileage & timing, but thing is B-die are kinda rare breed nowadays & not to mention comes with bigger price tag. next best alternative would be Hynix that can do 3600 @ CL16, but u gotta make sure they are binned for AMD & u have a pretty decent board & IMC (something which u cant really choose).

thanks for the info

New toy in a small footprint.. Pairing it with 2600X

woot!!! cant wait for d results bro...

i am on ryzen 2600, managed to get to 4.1 on 1.35v, and turned on XMP for my ram for 3 instead of 3.2 and everything works fine and smoothly. (i used prime95 to test the cpu, 80-83c max temp, never bothered going further)

cpu temps on idle 30-32c, on load when playing game wont reach 55c.

i see huge improvements on game like black desert online.

edit: using a normal idcooling aio 120 auraflow

happy to join the ryzen family

welcome to d family bro, pls do a screenshot so that i can update d entry on 1st page. no need to prime so long, for normal entry even hyper pi 32m will do...

noted. will post it here when im home!

waiting for ebucket to have the xpg d41 8gb to come back in stock XD

i'd suggest u do another once ya new ram is in d house bro, pls submit SS & details with format as below:

Username | CPU | Highest OC | Motherboard | Cooling

Thanks.

AMD Ryzen Memory Tweaking & Overclocking Guide by 1usmus
Hynix C-die @ 3800 CL16

https://www.techpowerup.com/reviews/AMD/Ryz...clocking_Guide/

However look at the performance numbers, Samsung B-die beats Hynix C-die at the same RAM clock speed.

my very own attempt on older gen Ryzen...

ah_khoo | Ryzen 3 1300X | 4100MHz | B350 Tomahawk | TT Water 3.0 Extreme

CPU, RAM and mobo are strong at delivering DDR4-3600 CL16.
Currently all sub-timings are auto-set by BIOS. Hence, the low RAM bandwidths and high latency.
Next up, will fix the efficiency issue by tightening up the RAM timings and probably still able to reduce the voltages a bit.

owikh84 | ASUS ROG Strix B450-I Gaming | G.Skill Trident Z RGB DDR4-4266 CL19 (Samsung B-die) 2x8GB | DDR4-3600 CL16-18-18-38-1T @ 1.450V | vSOC @ 1.15v

job very well done bro... gotta love those bdie

nice cili padi board too... how's d mileage on d cpu itself bro?

B-die is fun bro, you should get some and play again
Now at 3600 CL14, hopefully can get it stable at 1.40v.
Haven't play with the CPU OC yet cos now on stock cooler.
Just installed few hours ago and straight away hentam DDR4-3600
Will take it for a spin on custom wc later when I got time to swap the CPU waterblock with AM4 bracket.

I have bro, but I think is celup one... oem sticks but with bdie label. in thaiphoon burner also not recognized, & cant do 3200 @ 14-14-14. so I pretty much confirm it's celup one...



here's a quickie @ 1M...

There are good and bad B-dies, even PCB design (A2 > A1) can give different OC potentials. They don't like to be hot, prefer lower voltage. It is recommended that an active cooling fan blowing towards the RAM sticks.

Ehh I thought 1m bench is usually used for testing CPU OC. For RAM OC better use 32m, although it will not confirm 24/7 stability (HCl Memtest will do).

I'd recommend using Ryzen Timing Calculator to tighten the RAM timing and improve the performance efficiency. Key for achieving RAM OC stability is to find the correct combination of procODT and RTT etc, all of these possible values can be obtained from RTC.

I continued tightening up the RAM timing while reducing the voltages.
Now with RTC 3600 Fast preset, stable HCl 300%.

owikh84 | ASUS ROG Strix B450-I Gaming | G.Skill Trident Z RGB DDR4-4266 CL19 (Samsung B-die) 2x8GB | DDR4-3600 CL14-15-14-28-1T @ 1.425V | vSOC @ 1.075V


Update 1: 3666 Fast preset appears to be a successful run as well...

owikh84 | ASUS ROG Strix B450-I Gaming | G.Skill Trident Z RGB DDR4-4266 CL19 (Samsung B-die) 2x8GB | DDR4-3666 CL14-15-14-28-1T @ 1.475V | vSOC @ 1.150V


Next, I will tighten the tRFC's again to improve the latency or may go straight for 3733 (hopefully stable).

Update 2: Managed to complete AIDA64 benchmark at DDR4-3733 CL16 @ 1.49v/1.175v, not stable in HCl though:

that was some masterclass attempts bro... superb!!!

will try to push d bdie celup if happened i have time...

Looking at the high vSOC, I think I might have hit IMC limit of my chip. So far stable RAM OC maxes out at 3666, 3733 seems hard even with relaxed timings and increased/excessive voltages.

DDR4 3666 @ CL14 is very2 impressive already bro, i'd be dead happy if 3600 is doable on full fledged ATX board. hopefully DDR4 4000 for 24/7 is doable on next gen...
