[SOLVED] Dual channel not working

[Zaltsi13]

Hi i used 3x8 ram i cleaned my cpu water cooler today and than i plugged the cpu cooler back and than the ram not working well all the sticks work good alone but its not working dual channel or 3 sticks...

Could you post your system model or specifications.
Dual = two
For RAM to run in Dual channel mode it requires 2 or 4 RAM modules.
There are some motherboard that could run two RAM modules in dual channel mode and the 3rd RAM module in single channel mode.

Ok i will post my spec
And btw what is better dual channel or 3 ram stick ?

motherboard - aorus gaming k3 z370
Cpu - i7-8700k
Water cooling - corsair h100i pro rgb
Ram sticks - corsair vengeance ddr4 cl14 2400mhz

And again what i did is changing thermal for cpu and clean the fans and then for some reason my ram not working

As far as i know that motherboard supports dual channel mode with either 2 or 4 RAM modules.
The RAM could still work but it won't take advantage of double memory bandwidth.

If the RAM was working (even in single channel) and now it isn't working after reapplying thermal compound then the CPU is not seating properly or pins are not making contact with the CPU or a pin could be bended.

Its so wierd its sometimes work with 1 stick and somtimes not

 

[feather58]

are you plugging the 2 dual channel sticks into the designated positions marked for dual channel?

Beep pattern?

I dont think its cpu problem i disconnect the cpu cooler and still 4 long beeps and 1 short i think its ram problem but idk how to fix

Reset the BIOS

Reset your BIOS.
Power off and disconnect the power cord.
Press the power button for 20 seconds to discharge capacitors.
Remove the CMOS battery.
After 5 minutes, re-install the CMOS battery, insert only two RAM modules on RAM sockets 2 & 4 ...connect power cord and power on.

Not working

Yea i test more things its probably ram problem

It could be the RAM but you need to inspect the CPU socket. The CPU has an integrated memory controller and a single bend pin in the CPU socket could cause many RAM issues.

Try loosening the screws holding down the CPU cooler. There is a weird, known issue that affects DDR RAM channels when the CPU cooler is too tight.
Note that, after loosening it a bit, the CPU cooler should still be tight enough that it does NOT move if you try to move around the heatsink. Also, verify that you are using all the correct parts (spacers, screws, etc.) for the heatsink with that motherboard.
