Use testmem to see if there's any error, if nothing then your system is good.

xmp overrated anyway. Best is still manually overclock your RAM.

From what I remember those using 2600 write is normally the CPU around 65 to 75 C while GPU is 75 to 85 C.
It very much depends on your casing, cooler, airflow, and room temperature.

My Gigabyte mobo recently updated to F40 bios, now idle temp drop about 2 to 3 C compared to old bios.
I guess it also depends what manufacturer want the temp be shown too.

3700X only gaining 10 to 20% over 2700X
If using X470 mobo I wonder will the result still the same.
Feels like too small improvement to justify the cost of few hundreds ringgit to upgrade.

I got same RAM and it stable at 3200 18-19-19-46 1.25v
Maybe it depends on mobo compatibility.


Isn't that show 3600 and 3200 better than 4000 because they have better timings?

So going beyond it does not bring benefits?


How you measure the performance?
I use aida64 memory benchmark, 3200mhz give me 72.9ns latency while 2666mhz give me 77.8ns latency
Choose to stay with 3200mhz since everything feels much snappier.
Didn't try 2866mhz or 2933mhz


I use DRAM Calculator to get the starting point and slowly adjust from there.
I tried 1.35v can reduce the timing some more but finally decide to stay at 1.25v as don't want it's lifespan shorten.

You using the latest F40 bios?

I think this bios version have a lot of problem. Someone before mention the bios boot to default RAM frequency whenever starting the PC, only by entering bios and choose save and reboot will it use the saved OC RAM frequency. After I update my bios to F40 I also encounter exact same problem. Every time have to enter bios when start the computer. Now after I flash back to older bios ver no more issue with wrong RAM frequency.

Saw this thread on reddit, could be incompatibility with new CPU or Win 10 latest update issue

WARNING! Samsung NVME SSDs also subject to WHEA errors on Ryzen 3000 / X570
EDIT: Seems Intel SSDs are also affected. It's perhaps probable that all data storage devices that interface via PCI-E are affected.
EDIT2: There are reports that "putting an NVMe SSD in an m.2 slot that supports both PCIe and SATA (even if you're running in PCIe mode) eliminates the issue."
EDIT3: A Windows 10 bug from July 10th could also be the culprit: https://www.bleepingcomputer.com/news/micro...s-after-update/

High performance when I use get better benchmark than balanced, but only small difference. This is on 2700X

On daily usage I just use power saving, it only run on half of the cores which is enough, there's no feel of lags. When there's full load continuously for few seconds only it will activate the remaining half of the cores.

Install HWINFO64 to see your CPU temperature. It usually fluctuate between idle and some load.

Usually mobo manufacturer got program to control the fan speed. Set the fan speed so that idle and some load temperatures the fan spin speed % not too far away.

I don't think can install the heat sink wrong way. You maybe have bad airflow case. Are you using m-atx case?

If you want to prevent the idle temp from fluctuate too much you can change the windows power option to use power saver plan. This slow down the CPU from boosting too early, so your idle temp remain more consistent. For my case it fluctuate around 2 Celsius when idle. Don't feel any slowdown on daily usage, when there's heavy load it still can boost to max speed just fine. If you need faster boost from the CPU such as when playing games then only change back to balance or performance plan.

4k tv should be able to play even h265 video using it's own video player. If got WiFi it can just stream the video file from your network.


I think because your matx case and ryzen heatsink fan combination that lead to bad air flow.

If using balance mode it fluctuate a lot, 45 to 55 celcius. In non air conditioning room. The CPU keep boosting for every slight process. You can see your CPU current speed and graph on task manager. When in power saving mode it's only 38 to 40 celcius.

I recommend you try power saving mode first to see does it fix your fluctuate issue.


You can adjust the fan to be on small linear increment from 40 to 55 celcius. So on these range the fan will not spinning too fast. 65 I think a bit high already.


It all come back to does the system have good components, good vrm, good cooling. Failing on any of these will resulted on the CPU not able to boost or sustain at max speed.

You need to go into bios.

If you want default max speed 3200mhz, choose the XMP profile and change the RAM voltage to 1.35v

If you want to OC the RAM then more things need to do.

Try changing Power Options to use Power Saver.

Then better get the 3700X instead.

Or ask any seller or shop that can flash the bios using their CPU, for a fee of course.
Faster and less hassle of buying and sell back the CPU

Those shop that also do a lot repairing sure willing to do bios flashing.
PC shop that's more like boutique shop one no need to waste time asking them.

Your player in PC need to support bit streaming. Then your receiver need to support the sound format. This if using HDMI.

If your speaker are those that have those front/rear/center&sub 3 plugs then your sound card need to support surround sound, then Sound setting change to your preferable number of speaker.


Your PC player of course have to set to mixing the audio to how many speaker you have.

Then check your PS4 what is the format it output, whether PCM or DTS or Dolby Digital. Then match it on VLC.

Another thing is your video source the audio format must be supported by your speaker or VLC must be able to convert it to format that your speaker support it.

If the format is PCM then your PC audio setting need to change the speaker number to 5.1 like my earlier picture.

What is the downloaded video's sound format is? Your speaker only support DTS and Dolby Digital. If it's DTS:X or ATMOS or AAC/AC3 then the bitstream won't work.
One way to get around this is by using filter that will convert the audio to DTS or Dolby Digital 5,1. I'm not sure if VLC have such function, last time I use MPC with AC3 filter to do the conversion.

Direct from pc the speaker detect it as DTS but go through hdmi>TV>optical>speaker, speaker doesn't detect it as DTS?
Maybe your tv doesn't enable the bitstream passthrough or doesn't support that format for passthrough.
