Audio encoding
Naposledy sme sa zaoberali základnou doskou, ktorá, ktorá je aj vďaka nižšej cene vhodná najmä na použitie s lacnejšími procesormi. Teraz tu máme o zhruba 50 eur drahšiu Gigabyte B660 Aorus Master DDR4. Príplatok tu má jasné opodstatnenie a odzkadľuje sa na lepších vlastnostiach. Napájacia kaskáda je výrazne efektívnejšia, chladiče sú účinnejšie a výbava je celkovo bohatšia, vrátane svetielok.
Audio encoding
Test environment: Audio encoding is done using command line encoders, we measure the time it takes for the conversion to finish. The same 42-minute long 16-bit WAV file (stereo) with 44.1 kHz is always used (Love Over Gold by Dire Straits album rip in a single audio file).
Encoder settings are selected to achieve maximum or near maximum compression. The bitrate is relatively high, with the exception of lossless FLAC of about 200 kb/s.
Note: These tests measure single-thread performance.
FLAC: reference encoder 1.3.2, 64-bit build. Launch options: flac.exe -s -8 -m -e -p -f
MP3: encoder lame3.100.1, 64-bit build (Intel 19 Compiler) from RareWares. Launch options: lame.exe -S -V 0 -q 0
AAC: uses Apple QuickTime libraries, invoked through the application from the command line, QAAC 2.72, 64-bit build, Intel 19 Compiler (does not require installation of the whole Apple package). Launch options: qaac64.exe -V 100 -s -q 2
Opus: reference encoder 1.3.1, Launch options: opusenc.exe –comp 10 –quiet –vbr –bitrate 192

Why did you test VRM heating without heatsinks?
It’s simple – to get an overview of which motherboards’ voltage regulators heat up more and which ones less. With a heatsink you would not get relevant results, because its higher surface temperature does not necessarily mean higher temperature of the VRM, but that it dissipates heat faster.
This can be seen well in thermalpad tests, where there are lower temperatures for VRMs with a lower surface temperature of the heatsink. The best would be to locate (by thermal imaging) hotspots without heatsinks, then apply a thermocouple to them, return the heatsink and measure like that. Such a measurement procedure would also take into account the efficiency of the coolers and we plan to implement it in the future.
Hello, Merry Christmas to all.
I just bought this mobo, which comes with bios ver. E7E26AKB.1M2. However, when I go to official website, cannot find this bios version. I also tried to update this mob with the latest 7E26v17, but my m-flash is not reading it at all from my usb stick. I tried Fat 32 and NTFS format, but without success. Can your team give me some advice what to do? Thank you.
It is possible that the version the mobo came with has not been released separately for download and has been replaced by a newer/fixed build on the download page.
Sometimes the mobo maker releases several point releases of certain bigger version of the BIOS and the newer ones replace the previous ones, until something like a final version appears that will be kept in the downloads section permanently.
If you want to keep this older BIOS for backup purposes, you can dump it to disk for keeping.
As for why the update tool can’t read your USB stick – not sure, but it can happen. It is recommended to use USB 2.0-only drives, and also drives of lower capacity (under 32 GB), sometimes USB 3.0 etc can cause problems with detection.
Sometimes the UEFI supports reading the image from a SSD or HDD attached to SATA port too (Gigabyte does IIRC, although not sure it supports NTFS, dunno about MSI now).
Thank you Jan for a quick reply. I must mention that I also tried to update bios from M-flash going directly to hard disk and finding bios file. Unfortunately, it didn’t see my bios file at all. Dunno know what to do and how to update to the latest one version.
When you read the USB disk, can you see the directories and files at all, or is the drive entirely unreadable?
Assuming you didn’t make a mistake like not unzipping the contents of the zip (I don’t think any of the uefi updaters can read inside zips…), not sure what else could be wrong. Besides unzipping, try double checking if your motherboard really matches the file (but you likely did that…)
If you can’t get this to work from the BIOS, you could use the BIOS Flash button procedure (with PC turned off), described here https://www.youtube.com/watch?v=iTkXunUAriE
Hei Jan,
Thank you for assisting me. However, I tried to contact store (one of the biggest in Norway) where I live, and they said to me that it is custom bios (made be its company). So, I am still waithing answer from them, how can I put the latest original bios version. Best regards,
Dean
That makes sense. I googled this issue and the replies also mentioned that some system builders use customised BIOSes (could even be just custom logo added to the image to show say, “Puget Systems” instead of MSI) and such a board won’t recognize the stock BIOS.
In theory, as a last resort it is possible that these custom boards could be flashed to stock BIOS using tools like Flashrom or external flashers (those CH341 adaptors). But once you use these methods where signatures and CRCs are not checked, it can get dangerous, so I would recommend against doing this unless it is the last resort and the BIOS update is critically needed.
And even so, you would have to be extremely careful with checking that the board is the proper revision that has the exact same components everywhere. If the borad has not just custom BIOS, but also hardware customizations, that could cause problems, potentially fatal problems.
I have bad experience with this, because I accidentaly flashed a corrupt image, bricking a board without a BIOS flashback ability, and it cost me a lot of time and related hassles before I managed to repair it.
Also, nice post. Keep going a good work. Thank you once again.
very informative article and very good job. thank you
