Ah, ok. Well once again thank you for persevering with all of my questions.

Alright, now for my (hopefully) last question. Would you happen to know of any Bluetooth transmitters that would accommodate my AAC earphones?

Ah, that explains why the dongle had that delay. As for my other concern, would you happen to know of any high quality Bluetooth transmitters that would resolve all of the issues I mentioned?

I'm not quite sure I understand. The "Bluetooth device" in this context would be my Bluetooth earphones, right? According to the manufacturers they support SBC and AAC. Is it not possible for a transmitter to transmit audio to my earphones using the AAC codec?

I actually have another question for you, if you don't mind. Would you happen to know if any Bluetooth transmitters that can transmit AAC exist? I've been searching all over the internet for one, but I can't seem to find any.

I recently bought a pair of Bluetooth earphones and this Bluetooth 4.0 dongle along with them. The dongle works acceptably. However, it has a more limited range than I would like as well as a latency issue that causes music tracks that just began playing to actually start 1-2 seconds into the song rather than at the beginning. As a result of those issues, I began looking into Bluetooth 5.0 transmitters, thinking that acquiring one would help solve them. Ultimately, I ended up ordering this 5.0 transmitter / receiver, which arrived today. It did solve both of the issues I mentioned earlier, but it introduced a new, even more annoying one; that being distortion. For some reason, this transmitter introduces mild distortion into my music, whereas the dongle had no noticeable distortion at all. I tried to discern the cause of the distortion by doing things like testing both the transmitter's optical and 3.5mm AUX cables and using my PC's front jack instead of mobo jack, but nothing resolved the issue and the distortion remained. It was at that point that I realized that the transmitter had automatically selected "SBC" as the codec to utilize. My earphones, the HiFiMAN TWS600 support SBC and AAC. The transmitter supports SBC, APTX, LL, and "HD". I became curious about codecs, thinking they might be linked to the distortion, so I began to look into them (I now realize I should have done this *prior* to purchasing the transmitter). If I understood what I read correctly, SBC supposedly results in low quality audio, whereas AAC results in audio that is of above average quality. Admittedly, I'm not 100% certain that this is the cause of the distortion, as I couldn't find out what codecs the dongle supports, but I figure that must have something to do with it. With all of that being said, would any of you guys be able to definitely tell me what is causing the distortion? On top of that, if possible, I would also like recommendations for a Bluetooth 5.0 transmitter than supports the AAC codec. After being dissatisfied by the one I linked earlier, I planned to request an exchange for this, but decided to inquire here first before I set myself up for disappointment again.

Understood, thanks for taking the time to answer my questions.

You've been extremely helpful so far. I hope you don't mind, but I have two more questions. I think I almost completely understand this now. 1. In regard to your answer to question two. You mentioned that transmission over Bluetooth is done using a codec. I'm assuming that means that the digital audio is sent to the wireless headphones / earphones using the codec, right? However, I'm still not clear on if digital audio sent from the motherboard interacts with the ADC in the transmitter. I would imagine not, but I just want confirmation. 2. At this point I understand that transmitters have ADCs in them and Bluetooth headphones / earphones have DACs in them, but do either or both of those devices have amps in them?

Interesting... That leads to a few more questions, which hopefully you can help me answer. 1. Similarly to a poor DAC, if the ADC in a transmitter is of low quality, can the quality of the audio be affected negatively? 2. You mentioned that if the transmitter were connected to my PC using the optical cable as opposed to the 3.5mm cable, it would ignore the DAC and amp on my motherboard. That means that it would never be converted into analog audio and would be sent straight to the transmitter as digital audio. If that's the case, would it ignore the ADC and be sent straight to the headphones completely unaltered? 3. If the answer to question 2 is "yes", then is using the optical cable the way to achieve maximum sound quality?

Thank you for the extremely informative response. If possible, can you confirm that I understood what you said correctly? Assuming that the transmitter is connected using the 3.5mm AUX cable, the path is as follows: 1. Digital audio is first processed by my motherboard's DAC and amp, and then sent to the transmitter through the 3.5mm cable as analog audio. 2. Despite having already been converted to analog audio, the transmitter reconverts the audio into digital format, and then send the digital audio to the wireless earphones / headphones via Bluetooth. 3. The DAC and amp within the Bluetooth headphones / earphones then converts the digital audio into analog format, which is then audible to the wearer. Did I get that right? If so, does the transmitter have something similar to a DAC within it, except with a reverse effect?

As mentioned in the title, I would like help understanding the signal path that audio takes when going from a PC to a Bluetooth device, as well as the significance of 3.5mm AUX cables and optical cables in this signal path. I have the following questions. 1. When audio is sent from a transmitter such as this to wireless Bluetooth earphones, is it in digital or analog format? 2. At what point is the audio converted from digital to analog? Also, do wireless Bluetooth headphones / earphones have DACs and amps in them? 3. Assuming the transmitter is plugged into my motherboard via a 3.5mm AUX cable, do my motherboard's DAC and amp process the audio data at any point? What about if the transmitter was connected via an optical cable?

My hope was to run 3600MHz at CL14 timings. Do you think it can be done?

As mentioned in the title, I am trying (and failing) to overclock my 3200MHz Cl14 rated RAM to 3600MHz. It's possible that my RAM isn't even capable of achieving that frequency due to losing the silicon lottery, but in order to definitively determine that, I would like to make sure I am performing the overclocking process properly. Using the BIOS of my Gigabyte X570 Aorus Elite motherboard, I: 1. Enabled the XMP profile, which allows the ram to run at its rated speed of 3200MHz CL14. This, if I understand correctly, should take care of setting the frequency, timings and voltage without me having to set them manually. 2. Using the "System Memory Multiplier" option, I set the ram to a frequency of 36.00. If I'm not mistaken, this should overwrite the frequency set by the XMP profile, but maintain the timings and voltage. 3. At first I left the "DRAM Voltage (CH A/B) option on its default setting, "auto", but when my PC crashed, I upped the voltage to 1.4v, which crashed again, then 1.45v, which resulted in another crash. Finally, I then tested 1.5v, which still resulted in a crash. 4. I then returned DRAM Voltage to its default setting and tested lower frequencies such as 33.33 and 34.00, but those frequencies resulted in eventual crashes as well. I find it hard to believe that the absolute limit of my RAM's overclocking potential is the XMP profile, which to my knowledge is supposed to be a maximum "safe" overclock. Is there something wrong with my methodology that is preventing me from reaching higher frequencies? Edit: As an addendum, I have no idea what the "XMP High Frequency Support" option does and couldn't find any mention of it in the motherboard's manual. If anyone could elucidate that, I would greatly appreciate it.

Ah, turns out I do have Samsung memory, thanks for telling me about GPU-Z.

Oh? Would you happen to know if my GPU model has Samsung memory?

Alright, I'll give 3DMark a try and see if I can figure out my optimal overclock. Thanks for the advice. Edit: Actually, no I won't because I have to pay for it. Off, to the Heaven download page I go.

And what do you recommend using for the benchmarking?

Alright, so how can I determine the optimal overclock?

I am currently trying to determine the maximum optimal memory overclock for my EVGA GeForce RTX 2080 Ti Black Edition. I am doing this by increasing the overclock 100MHz at a time, and then playing Apex Legends for about half an hour afterwards to watch for graphical artifacts / crashes. I did this repeatedly and began to get very minor graphical artifacts at +500MHz, but as I said, they were minor to the point of me not worrying about them. I continued this process until I reached +800MHz, but at that point, I had become suspicious, as +800MHz strikes me as "dangerously high". When playing Apex with the +800MHz memory overclock, I was still only receiving minor graphical artifacts with no crashes. After that session, I decided to do more research on this subject online and eventually came across a post on a different forum mentioning that a memory overclock that is too high can actually decrease performance due to something known as "error correction". The post also mentioned that the graphical signs of this occurring would not be as obvious as the signs of a core clock that is too high and at times might not be visible at all. I'm fairly certain that the aforementioned scenario is occurring with my graphics card, as I just can't believe the EVGA RTX 2080 Ti Black Edition can run stably at a +800MHz memory overclock. So my current predicament is determining a memory overclock for my graphics card that is high enough to maximize performance, yet low enough to prevent error correction from occurring. Does anyone have any advice on how to achieve this?

Now that you mention it, its capability to boost itself when performing demanding tasks would make overclocking pretty pointless wouldn't it? That fact completely eluded me until I read your post.

If I understand correctly, you're saying overclocking the 3900x has potential to decrease performance? Even in a task such as gaming?

My goal was to improve gaming performance. Not to imply that I'm dissatisfied with my current gaming performance, but I'm sure I can get a little more performance out of it while still being within safe voltages and temperatures.

What are the options? As in what options do I have to pick from if I select it?

As mentioned in the title, I'm planning to overclock my Ryzen 3900x to 4.2 GHz in the Gigabyte Aorus Elite BIOS. I'm aware that doing so is as simple as setting "CPU Clock Ratio" to 42.00. However, I'm not familiar with the "CPU Clock Control" setting. Would anyone be willing to explain to me what exactly this setting does and if it is relevant to overclocking?

Interesting, I'm too lazy to bother with the BIOS, so I guess the results I acquired from Afterburner will suffice.
