ASRock 990FX Extreme3 RAM Problem.

[KonTiKi]

Heyaa,

Yesterday, I noticed how my computer kept hanging crazy because of amount of programs I was running which it didn't happen before. Then I noticed in Task Manager that my RAM has AVAILABLE of 4 GB. But I have 8 GB of RAM installed (2x4GB). Started to look through forums and scratching my head what the hell happened, there was suggestion that I should go in msconfig>boot>advanced options and uncheck Maximum memory which was already unchecked. Going in BIOS I saw that my RAM was running in single channel mode for no reason. Going through forums again suggested that I should do CMOS - after doing it and going BIOS it showed that RAM is now running on DUAL Channel mode and going in Task Manager showed that 8 GB are available. Then after few hours of using it my computer suddenly restarted and going again in Task Manager that AVAILABLE RAM is 4 GB. Restarting again and going in to BIOS showed me up again that my RAM is running on single channel mode (-_-).

Please HELP!

Try raising the DRAM voltage + 0.05 and the CPU/NB voltage up the same - also let us know the model number of the DRAM and what the CPU is running at. Also what PSU, could be a few things

Hey,

Sorry for late answer. I was away for a week. Anyway.

Rasing DRAM, CPU and NB Voltage didn't help. ASrock BIOS only would let me raise it by 0.15.

DRAM Model - BLT2CP4G3D1608DT1TX0CEU
PSU - OCZ ZX 850 W Plus Gold

And what do you mean by what the CPU is running at?

Is it OCed at all?

Nop. Never actually thought of OCing it.

To run those at 1600 may need the OC, might try at 1333 9-9-9-27

Well, I have already tried 1333 and 9-9-9-27 but still singe channel mode. Should I try to OC my CPU then?

Give it a try....are the sticks in slots 1-3 from CPU or 2-4

They're in 1-3.

I have approximately the same OS win 10 (on 450/450 120gb SSD), RAM (4+4 dual channel crucial ballistix tactical 1866MHz)and Motherboard ( 990FXExtreeme3). Cpu is amd FX8350 and graphics card is Gigabyte r7 260x winforce GDDR5. I don´t remember my PSU presice name, all i know it is Hyper 610W. .After i changed my OS from 7 to 10 (upgraded), my ram clock rose up a level to 2133MHz. I know hardware should not support this but it is. You prloblem is behind CPU. If it were behind PSU it would choke the CPU and graphics as well, missa thinks =).
