Dram light

[PcBeExpensive]

Hey, I was trying to find the limits of my RAM (so I was overclocking it) when my PC crashed, It now doesnt post. When I press the power button the fans spin lights turn on but it doesnt post. I've noticed the DRAM light on my mobo is on. HELP PLEASE!!

System:

CPU: R5 5600X

MOBO: Asus ROG Strix B550-F

RAM: Corsair Vengeance RGB SL (4 8 gb sticks)

PSU: Corsair RM650X
 

I have tried removing and reinstalling the coin battery, reseating all 4 sticks of ram. Please help me!

Crashing when screwing around with ram is normal. Refusing to post is sometimes too.  Clear your CMOS and reboot.  Your bios will be default again.  The coin battery thing should have reset you cmos though.  CMOS is just a name these days though.  That stuff is actually held in NAND. All removing the battery does is flip a switch that should clear the cmos in imitation of the original actual cmos.   Perhaps try another method of clearing like shorting the cmos pins. (Another fake system but a different one). That coin battery thing should work though, assuming there is actually causality here.  There might not be.   I’d say RMA your motherboard, but it could be that your ram went bad at that exact moment.

I cleared my CMOS by shorting the pins and it worked, the battery trick didnt. Whats weird though is that if I set my RAM speed to 3600 MHZ it was fine, now when I try to set it to that is crashed and I have to clear CMOS again. Is there any reason why that may happen?

Maybe mail asus and see if that board is supposed to reset when the battery is removed.  I was told the thing only actually powers the real time clock now.  The whole pull the battery thing is sort of just a manipulated affectation now.  They may have just done away with it.  Or they may not have, in which case if the thing is still under warranty you are due a repair (which will probably mean a new board because it’s easier)

Yes the board is less than 1 month old so I do have warranty. But why isnt it able to run my RAM at 3600 MHz like it used too?

Timings probably.  Default is like 2100 and all the consumer grade CPUs aren’t guaranteed to go past 3200.  you have to have to either hand tune it above that and hope or use XMP/pbo and hope. XMP/pbo is the motherboard manufacturers doing such hand tuning ahead of time.  Sort of an auto overclock for memory.  Doesn’t always work.  Sometimes you have to hand tune anyway. 3600 cas what btw? If it’s 18 or higher you can get such memory new for $50 cas 16 is more expensive and cas 14 is really expensive. 3200 cas 16 is basically the same speed as 3600 cas 18
