Hi guys
I bought recently a new mobo : ASRock 970 Extreme3 R2.0
http://www.asrock.com/mb/AMD/970%20Extreme3%20R2.0/?cat=Memory
and 2 memory sticks G.Skill RipJaws X Series 8 Go (2x 4Go) DDR3 1866 MHz CL9
The plan was to remove my phenom II X3 720 BE from my old mobo, an Asus M4A77TD Pro
http://www.asus.com/Motherboards/M4A77TD_PRO/specifications/
and plug it the new AM3+ mobo with the 2 new memory modules
However when I restart my pc with the phenom II X3 720 BE into the new mobo, nothing happens, no display on screen, the mobo have no onboard led, all the fans works fine ( cpu, case and graphic card)
no beep ( tried the external speakers since my case dont have one), no post
What I did :
- unplugged all hdd and pci cards leaving only the cpu, 2*4 Go of ram and radeon hd7850
- unplugged the 2 memory modules - G.Skill RipJaws X Series 8 Go (2x 4Go) DDR3 1866 MHz - one by one , no change ; I plugged them into my old mobo with the same phenom II X3 720 BE and are detected correctly in the bios and in Win7
- I plugged the Kingston 4 Go (2x 2Go) DDR3 1333 MHz memory module from my old mobo into the new one to check if it could be a memory issue, still no chance
- my power supply is an FSP (Fortron) EVEREST 85PLUS 500, it have 2 4pins ATX 12 V connectors, I tried both of them on my old asus mobo since it only need 1 , both works fine , same goes for the 24 pins connector
- i did a clear CMOS
I am a bit lost here , I think it could be a motherboard issue, any help would be appreciated Thanks
PS : my 2 memory sticks are not on the Memory Support List, however i doubt they would prohibit the pc from starting and if plugged into the 5 years old Asus M4A77TD Pro they are correctly detected
