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

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.

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

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.

From reddit it seems PBO is still broken on ASUS B450.
Not sure if other vendors managed to fix it or not though.

Btw, curious how come some users managed to get PBO worked?!

Karhu 10000% passed at 3800 16-19-16-38-56?
Mind sharing your ss?

B-die is 2666 CL19, pretty much the same true latency but less bandwidth.

2666 CL19: 2000/2666*19 = 14.25ns
2933 CL21: 2000/2933*21 = 14.32ns

Ya, curious about A-die's OCbility vs B-die.
We gonna wait and see later...

Holiday benching with 3600X + C8H that I recently purchased from shopee at a good deal



Starting off with CPU OC, so far I've tested 3 types of coolers at 4.2GHz OC @ 1.375v on all cores.
Thermal results based on Prime95 v29.8 b6 custom blend 1344K min/max for 30mins as follows:

Cooler	Min (°C)	Max (°C)
AMD Wraith Spire	50.0	92.3
Raijintek Orcus 240mm	47.1	79.8
Custom WC	40.5	74.4

Max OC under 1.40v should be 4.25GHz, thermal results under custom WC as below:

CPU Clock	Min (°C)	Max (°C)
Stock @ 4.1-4.125GHz @ 1.28v	39.6	66.6
4.2GHz @ 1.375v*	40.5	74.4
4.25GHz @ 1.375v	40.3	76.3

* Can still be reduced a bit

Some benchmarks at 4.25GHz OC:

Cinebench R15:


Cinebench R20:


Hexacore CPU comparisons:

CPU	CB R15 MT	CB R15 ST	CB R20 MT	CB R20 ST
3600X @ 4.25GHz	1695	199	3866	490
8700K @ 5.00GHz	1650	217	3962	517

4.3GHz is bootable but sometimes CB R20 crashed at 1.425v so I think more juices is required to get it stable.
Will revisit this later and update in this thread...

Continuing with RAM OC, so far hasn't been so impressive mainly due to high latency issue.
It could be that the latest DRAM Calculator v1.6.2 by 1usmus has decided to set the subtimings too loose that eventually hitting the RAM performance. Maybe need further tweaking to optimize the bandwidths and latency.

RAM OC with SK-Hynix AFR:

3466 16-19-19-40-1T @ 1.41v:


3533 16-19-19-40-1T @ 1.45v (not stable):


RAM OC with Samsung B-die:



3600 14-15-15-30-1T @ 1.45v:


3800 16-17-16-32-1T @ 1.41v:


4000 16-17-16-32-1T @ 1.45v:


4133 16-17-16-32-1T @ 1.45v:


Again, still need to figure out how to reduce improve the efficiency.
Aim for 3800 CL14 stable but I don't think possible with the current ADATA D80 sticks.
Later I swap to my TridentZ RGB 4266 kit and see how much I can push.

I need to recheck this later as the GDM and PDM are mixes of enabled and disabled as per recommendation by DRAM Calculator.

Edit: Okay I just rechecked and found that my Power Down Mode has been disabled right from 3466 all the way up to 4133. So, the source of high latency could be from other settings.

3600X 4.3GHz @ 1.45v, I think I'm pretty much hitting the ceiling already. Yes, note the voltage is exponentially increased. Thermal results based around P95 28.9 b6 custom blend 1344K min/max FFT for 30mins:

CPU Clock	Min (°C)	Max (°C)
Stock @ 4.1-4.125GHz @ 1.28v	39.6	66.6
4.2GHz @ 1.375v*	40.5	74.4
4.25GHz @ 1.375v	40.3	76.3
4.30GHz @ 1.450v	40.0	82.6

* Can still be reduced a bit



Cinebench benchmark scores also improved a bit:

CPU	CB R15 MT	CB R15 ST	CB R20 MT	CB R20 ST
3600X @ 4.30GHz	1715	201	3893	493
3600X @ 4.25GHz	1695	199	3866	490
8700K @ 5.00GHz	1650	217	3962	517

CB R15:


CB R20:

Latest AGESA 1.0.0.3 ABBA seems to have fixed my 3600X's boost bug that I had earlier, now I can see one core is boosting up to 4.4GHz as per AMD's original specs. CB R20 runs with everything default:

BIOS 0803:


BIOS 1001:

Voltage is set by ASUS BIOS so nothing to do with AGESA, temperature is stock cooler vs custom loop LOL.

Good point, but I was referring to the load voltage behavior being controlled by BIOS LLC settings.

BTW, I'm still having high memory latency (70ns+) and low bandwidth (50k+ MB/s) seen in AIDA64 benchmark.
Tried everything such as reducing tRFC down to 160ns, PDM/GHM on/off, tRC 42-44, tFAW 16-20, new ABBA BIOS etc none of them seems to solve the issue.

Well done on the 2000% HCl.
How's your AIDA64 benchmark score look like?
Good to see MemTweakIt is working on a none-ASUS board as well.

BTW, did you notice that HWMonitor is giving you vCore up to 2v max?
I'd suggest try to avoid using this software, or it could be that the GIGA boards are still using iTE Super I/O chip, which reads voltages not as accurate as the Nuvoton chip.

3800 14-16-14-28-1T @ 1.480v

Bingo, not being able to do FCLK 1900 at DDR4-3800 with my 3600X chip has seriously killed my latency and bandwidths. There's a 10ns penalty for 3800/FCLK 1866. At 3733/1866 (1:1) I could get sub 70ns and better bw.

I also came across an article from an ex-ROG staff doing comparisons of memory performance on 3600X/1xCCD vs 3900X/2xCCD: https://elmorlabs.com/index.php/2019-07-10/...0-investigated/

We can see significant differences in terms of mem bandwidths with 3900X over 3600X.
It is also suspected that dual-rank and 4x8GB DIMMs are capable of delivering higher bw.

Cant post at all, stuck at debug code 07 displayed on mobo.
I've tried playing around with VDDG up to 1.1v, SOC up to 1.15v but none of them seems to be helpful.
I also tried BCLK 102 with FCLK 1866, getting the same error code.

My BIOS settings as follow:

ya I think 1.1v is quite high already, I even tried 1.2v SOC just now.
Not really want to go higher otherwise I will kill the IMC, I think I'm just one of those unlucky ones with FCLK capped at 1866.

3733 14-16-14-28, FCLK 1866:
