R2 processor failure

Hello,

I have an AW M18x r2 and two days ago, when I turned on the computer, I've been welcomed by 7 bips.
I think the processor is broken. It was a 3920xm. Can anyone tell me if the problem is really a processor failure and what model can I buy to replace the 3920?

thanks in advance

 

Seems like the cpu: http://en.community.dell.com/owners-club/alienware/f/3746/t/19451762

Thanks a lot for your answer

 

Take a good look, folks! This user has a 4-year old laptop and is still able to repair and upgrade it with ease. Worth every penny.

Hope it works out! Good luck. The days of this being possible are over.

 

i7-2920XM should also work and it's cheaper.

 

I doubt the CPU has failed. More likely the mobo. @Swick1981 appears to have two M18xR2 with sudden death syndrome. M18xR2 mobos seem to have a short life expectancy. If yours is dead that makes about 8 that I have seen 'expire' for no apparent reason in the past 1.5 years. The part is no longer in production, so you will need to find a used one some place.

It will definitely work, but it's not as powerful as 3920XM or 3940XM. I will also have issues with RAM running 2133 (hit or miss above 1866) and it does not support PCIe 3.0 so better to stick with Ivy Bridge to avoid downgrade. But, again... very unlikely the CPU itself has died. If I were a gambler I would bet it is the motherboard and not the CPU.

 

If that's the case, eBay still has plenty. Be sure to check the seller feedback and see if they accept returns (just in case).

I have a board for sale if you need one, PM me

 

I ordered a processor on Ebay. Hopefully it will solve the problem. In 4 years of warranty, Dell changed the motherboard twice, both nvidia twice and the processor once. I take it this laptop is not the most reliable thing on earth, probably due to overheating problem.
Raidriar, I'll let you know if the processor is not enough to solve my issue. Thanks for the offer

 

This laptop doesn't have overheating problem if it's pasted correctly

 

Well the paste has been applied by a Dell technician every time and I use a cooling support for the laptop. I spend my time using dry air spray to clean the vents but still, the laptop gets very hot in games.
Anyway, I hope the processor is the only thing that is broken on this machine

 

Having a High end laptop is like having a sports Car. When you use it, it is a must to monitor several parameters, like heat. I find it very weird that so many componets needed to be replaced in such a short time. Also, dell techs use low grade paste. I find hard to believe that after they switched a component, they applyed IC7!

 

As others have said, it is rare to have an Intel CPU fail. I've owned dozens of different Intel chips, none of them ever failed (knock on wood). There are 2 users on this board that had random 7 beep failure and turned out to be a board problem. Let us know how the replacement goes.

As far as cooling goes, it is imperitive you get temperature under control. My M18x stays very cool idle, and warm (NOT HOT) under full load. For example:

3920XM clocked at 4.2GHz 4 cores: about 55 idle/light use/internet, about 75-82 under FULL 100% usage. I used liquid ultra paste for the CPU.

980M: Sits about 49-55 idle/low usage, abut 69-72 degrees tops under full load. I used 1mm ebay thermal pads + antec formula 7
