Alarm

Hello. I am overclocking an Nvidia GTX 1660 Super with MSI Afterburner. When i overclock with the sliders, everything works fine and my VGA when on idle runs on lower clocks (like 300mhz). When i try to overclock or underclock through the voltage curve, i noticed that the GPU core is always running at max mhz no matter if the card is on idle or not. Why is that? Is there a way to avoid this? I try to run at a bit higher frequency while lowering the voltage to reduce some temperature, but i dont want the card to run constantly at 2000mhz and use 50watts even on idle. Thank you.

That was really helpful. Thank you for your answers!

Thank you for your answer. Once the cpu is on 100% load, not a single core goes above 4ghz . I checked with CPUID the max clock speed while performing a stress test, the max was at 4070mhz on all cores. Once i stopped the test, the boost speed of 4.4ghz was reached. Sounds sort of exactly the opposite of what would be ideal, meaning that its on 100% load you need the boost , not while on idle.

Hello ! This question might have been asked already but i got lost in so many related topics about Ryzen 3 and Boost clocks. In detail, i got a Ryzen 5 3600x, which under normal conditions i see the clock speeds fluctuating from 3.8 to 4.4ghz, even while on idle (i assume this is fine) Now to my question, when the CPU is under 100% load instead of reaching 4.4ghz , all cores run at about 4ghz with a CPU temp of ~85c. Below is also a diagram showing what i mean. The flat line near the end of the graph, is when the CPU was at 100% . Why is this actually happening? Is the CPU throttling at 85c temperature ? Update. It looks i found my answer here

I have downloaded the first one after all. I am not sure that the sound is managed by Realtek chipset here but rather from the NVidia graphics cards. Maybe i understand something wrong. Still after installing the Realtek drivers, i have the same issue. Maybe because i am not using the audio interfaces Realtek is managing.

Thank you for your fast reply. On the MSI webpage for my motherboard ( https://www.msi.com/Motherboard/support/B450M-MORTAR#down-driver&Win10 64 ) i see 2 different audio drivers, Realtek HD Universal Driver Realtek High Definition Audio Driver Which one do i need and whats the difference between them ?

Hello. I got a PC with an Audio Realtek ALC892 chipset. The PC is connected to an AV Receiver through HDMI and then the AV Receiver connected with a TV again through HDMI. My issue is that Windows, does not identify automatically the number of audio channels a video/audio file has. As a result i have to always go to the audio settings and select manually Stereo (2 channels) if i want to listen to music, or 5.1 surround if i want to watch movies. So for example if i play a file containing 5.1 channels and my settings are set to Stereo, windows will not change to 5.1. That is pretty annoying considering that a 50$ TV Box could handle this much better and was identifying how many channels it should send to the receiver. Isn't there any way to make windows send always send the correct number of channels to the receiver based on the source file ? Note. I have not installed the Realtek audio drivers. Not sure that would make any diference.

Thank you for your fast reply. I am still not sure. For example i see in the pcpartpicker the following dimms that are compatible with the motherboard CMW16GX4M2D3600C18 (according always to pcpartpicker). I've checked the MSI support list though and this code once more does not appear at all. So there is no guarantee that those will be compatible. Unless i understand something wrong.

Hello. I ordered the MSI B450m Mortar Max (CPU AMD Ryzen 5 3600x) and have a lot of difficulty finding the appropriate RAM with RGB. I am looking for 2x8GB DIMMs clocked at 3600mhz CAS 16 or max 17. Alternative 2x8GB DIMMs clocked at 3200mhz CAS 14 or max 15. Almost anything that i found at a decent price at 3600mhz , Crucial Ballistix, Corsair Vengeance, HyperX Predator) is not listed in the supported memory of my motherboard (can be found here: https://www.msi.com/Motherboard/support/B450M-MORTAR-MAX#support-mem-18 ) Please do let me know if you have any suggestions at a price range under 120 Euro/USD . I wouldn't believe it would be that hard to find some DDR4, but the supported list, looks pretty limited and lists main 3200mhz modules. Thank you

In any case, i think i am dropping the idea with the RX 5700 or 5600 XT. I just found that the Gigabyte 1660 Super OC is at 250 Euro. Thats a difference of 70-80 euro to the next decent RX 5700. As for the RAMs i might look better with 3600mhz and CAS 16 if possible, as some of your proposed.

Well most of the DDR4 at 3600 i find, are with CAS 16 like the Crucial Ballistix 16GB DDR4-3600MHz , which are also a bit more expensive. The rest of 3600 modules i find are with CAS 19 , compared to the 4000 modules that i find with CAS 18. I assume i wont be seeing any difference with either of those, so my guess was to go with higher frequency. As for the RX 5700, anything other than the Asus i mentioned, starts with 20-30 euro extra, so it increases also the difference compared to the 1660 and i start to wonder slowly again if it is worth investing 60-70 Euro more on the VGA. What i see though, is that the RX 5700 can draw almost double wattage compared to the Nvidia. That is an extreme difference.

So i can forget RAM above 3600 as it will be not supported by the CPU if i understand correct. Thank you all for pointing out about the RX 5700. Well lets say i started with a price tag of 200 Euro about for the VGA i am landing now on 300 slowly In any case, i wanted to go with Nvidia due to several people complaining about AMDs drivers. No personal experience. Currently i can find the ASUS DUAL RX 5700 evo for 310 So the price difference with the MSI Nvidia is not that huge. If the Asus is the best option out there compared with other RX 5700, i am not sure. I did check some comparison between the 1660 and RX 5700 and indeed there is a difference of 10-20 fps in some games. So you say this is a better choice. Now between RX 5600 XT and RX 5700 , i honestly can't find why would someone go with the RX 5600 XT.

Hello. Last time i was building PCs the Mhz on a CPU where with 3 digits and the MBs still had ISA slots. After a long time i plan to build again my own PC and need some of your help with a couple of things. Currently i am going with the following setup: CPU: AMD Ryzen 5 3600X MB: MSI B450M Mortar Max (or Asrock B450M Steel Legend) VGA: MSI GeForce GTX 1660 Super 6GB Gaming X Storage: M2 Samsung EVO 500GB (+ extra SSD) RAM: G.Skill Ripjaws V 16GB 4000MHz (2x8) CAS: 18 Case: Coolermaster MasterBox Q300L (3x140mm Fans) PSU: Corsair CX Series CX550 (or Be Quiet System Power 9 600W) 1) My main concern currently is RAM. I found those from G.Skill at 4000mhz which are priced almost the same as with 3200mhz CAS: 16 and 3600mhz CAS: 19 . Unfortunately i could not find the 4000mhz in the supported list of the MSI MB. In addition, i am not sure if the rest of the system can take advantage of the 4000mhz and i should focus maybe on lower frequencies. Please do tell me your opinion in that or mention better alternatives at the same price range. 2) I did an extensive search on motherboards and ended with MSI B450M Mortar Max and Asrock B450M Steel Legend. The differences on the hardware are minimal. About VRMs and stuff, i hear all kind of opinions, so i just ignore this as there seems not to be a conclusion on this. So my main focus stays on the BIOS (which is better), support for Ryzen 5 out of the box (Asrock may require a Bios update) and better support for ram at higher frequencies. Any suggestions here will be also helpful. All in all, i am not the user that wants to run at 4k with 6000fps. I just want to have a mainstream PC where i can listen to music, do some photo editing but have also the opportunity to play latest games with some average settings. Also, there might be some future plans for a lightweight overclocking, but not something extreme. Anything that my PC will be able to handle with the existing cooling setup. There are no plans in spending in watercooling or putting a fortune in the cooling system. Please enlighten me a bit about my points 1 and 2 . Further proposals on alternatives are also welcome. Thank you.
