It depends on the mobo and bios, cpu-z can't always get all the info that it tries to display, not a big deal. dual channel mode primarily is what slots you have dram in, which really has nothing to do with the chip configuration i. e. with most intel mobos, you can have 2 4gb sticks in the a channel of the mobo and an 8gb stick in a channel b slot and it will run dual although that's if the. Hey i use the corsair spec 02 case and im using the fan that came with it and dc mode in bios im wondering should i use dc mode or pwm mode on it. i would like to make it so i dont have to touch it again and is there a way to make it go on auto if it is possible? im using asus z97k.

I know dc mode in bios that the fans i have are dc because they only have 3 pins, but my motherboard can support 4-pin fans. i can toggle between dc and pwm mode in the bios. supposedly i can also change the "profile" and "speed" for my case fans, but literally none of the options make a difference. The bios setup program can be used under two modes: ez mode and advanced mode. you can change modes from setup mode in boot click to activate dc mode.

Option1: fan setting in bios select dc or pwm control according to your fan type. recommended fan curve: silent: minimum speed to 60°c, first slope to 50% . What is dc mode? bgunner : pwm = pulse width modulation, meaning the power pulses to the fan saving electricity and lowering the electro magnetic field that coil winding’s, located in all fans and electric motors, produce. dc in this case means direct current where the fans receive a constant flow of electricity to remain spinning. For the dc mode of cpu_fan connector, please enter bios->hardware monitor and set the smart fan manually for a try. the default setting for cpu_fan's dc mode has a lower voltage setting, the fan may not spin up if the cpu temperature is low. you can set it manually to check again. thanks!.

Hi, i'm using maximus gene vii and my mb bios or ai suite provides both pwm and dc mode for all the fans. some ppl say dc for chasis fan (3 pin) and pwm for cpu fan (4 pin). i wonder whether pwm is better than dc. at lest from the bios, i see pwm mode is a bit better than dc mode by providing. Pwm/manual fan mode in bios instead of dc/auto fan mode. i just built a new rig with a maximus viii hero, i5 6600k and corsair h100i gtx. when i installed the corsair link software the h100igtx cooler fan sensor is blinking red and @ 0 rpm. corsair tech support is telling me to disable pwm/manual fan mode in bios instead of dc/auto fan mode. Speed reading seems correct in bios as well. i read in manual and see on the internet there should be the option for dc or pwm in the bios hardware monitor. however, i can see only selected pwm mode and no option for dc. the cpu fan, being pwm, works just fine as expected. i am on a520m-a pro with the current release bios (no beta). can anyone. Common keys include f1, f2, f10, f12, delete, or esc. the correct key is usually listed when your computer boots up. if the bootup process goes by too quickly, you can use the following steps to reboot your computer into bios from within windows 10: click the windows start button. click the gear/settings icon.
