Need help with ram issues 1 stick works alone and so does the other but not both at the same time.

Specs:

I7-7700 (non k)

Ram: 

   1:8gb ddr4 2666mhz crucial ballistix

   1:8gb ddr4 2400mhz kingston generic ram

Gpu:Gtx 1080 ti xtreme aorus

Storage:1tb Seagate barracuda steam library and 240 gb kingston sa400 SSD

Mobo: Asrock b250m pro4 1.50 bios updated to 2.50 Supports a max of 2400mhz

Psu: Gigabyte p650w

 

So I was updating my bios and it was at 60% I left and came back the screen was black computer. shut off the computer manually and every time I open it i get a black screen but the fans keep spinning.

Next day go to a computer repair shop as my motherboard support didn't answer the BIOS chip was not working so the engineer at the shop removed it and programmed another one and soldered it to the motherboard and boom 

my computer was working again, when I went back home I added my other ram stick that I removed and my pc screen won't load either the computer keeps rebooting or it boots up and then doesn't do anything .

 

My computer boots up with 1 stick in any slot the 2666 or the 2400 but not both at the same time I tried cleaning the ram contacts using canned air for the motherboard ram slots and re seating the cpu and the cooler making sure it has good contact but still i'm bound to 8 gb of ram

My computer used to boot up with both the sticks in any slots whether running in dual channel or single

Perhaps that ‘engineer’ fucked your board.

 

on a second note; what slots are you using ?

[Kevin Sherif]

I tried using the first and 3rd slots then the second and fourth slots but now im using 1 stick on the first slot

Can it be that the newer bios doesn't like the different ram sticks with the different speeds?

Speed shouldn’t matter. Both sticks will run at the lowest rated speed. 
 

Have you tried every slot with a single stick ? 

[Kevin Sherif]

Yes

Somebady help me :*(

Could it be the newer bios is conflicting with the 2 sticks of ram or I need certain settings to make them work?

[Kevin Sherif]

Fixed it flashed back my motherboard to the older working bios with 2 sticks and now it works

Heh, that's interesting,  BIOS update can and sometimes will break RAM compatibility... 

 

I mean that's not too surprising,  just shows one of the bigger flaws of updates in general,  they aren't always a good thing. 

 

At least it's possible to flash back a BIOS so no real damage was done (except the soldering / repair costs)
