Damaged 740 BE

post #1 of 6
Thread Starter 
Tonight I was assisting my cousin with his PC that wasn't booting. (Ended up being a dead stick of ram)
In the process my 740 BE was dropped and pins were bent along with the corner of the circuit board. Pins were straightened and CPU went back into the mother board. However, now Dimm 3 & 4 no longer like ram. The computer had been working up until the project with 4x4GB sticks of Patriot 1600mhz ram. It now only runs with dimms 1&2.
Is this because of the damaged CPU? All the pins are there and the cpu sits securely to the board.
How dangerous can this be to my other parts?
Could something in Bios have shut down those two dimm slots?

Edit:
Motherboard is Biostar TA880GU3+

Moral of the story, don't let others touch your CPUs.

I dropped a Phenom 9600 a few years back and unbent the pins. Thing ran like a champ with no problems for over a year until I upgraded. Are you sure none of the pins broke?

2 sets of eyes went over the chip multiple times and the pins all seem to be there.

Weird. Have you tried resetting the CMOS jumper?

I doubt it's your CPU.

Any possibility BIOS options got changed? Four sticks of RAM on some IMCs don't play nice, so if voltage dropped it could cause weird problems until you removed two sticks.

What does it do? Saying "no longer like RAM" doesn't help redface.gif Does it hang during post? BSOD? Just refuse to aknowledge any installed sticks? BIOS recognizes it and Windows doesn't?

What does it do if you only put RAM in slot 3 and 4 and none in 1 and 2? What about just one stick in either 3 or 4?

It's more likely you damaged your motherboard without noticing it/your board just happened to become faulty than it is to drop your CPU and damage it without rendering it useless. CPUs are pretty durable. Ignoring damage from high voltage/dirty power, most of the time they either work 100% or work 0% if all the pins are there.

That being said ... you could be unique biggrin.gif

The computer had been running with the 4 sticks in it before the drop.
It boots normally with sticks in slots 1 and/or 2.
when sticks are inserted into 3 and/or 4; whether or not anything is in 1 or 2, It does not post and the onboard LED indicators read a memory error.


" most of the time they either work 100% or work 0% if all the pins are there. "
That makes sense to me, which makes the situation feel weird.
