RE: PN for the primary heatsink in a T7500?

Jump to solution
The U016F heatsink totally did the trick. Max temp is now 80C and under and both cpus are running the same temps as well. Great stuff. So now I ordered some X5675's for my other T5500 haha. Really appreciate everyone's help and responses. Really assisted me, Thanks.

The ironic part is that I said that U016F was the part a year ago and then many proceeded to say No that's not it without ever having tried it.

I think you are referring to wrong thread 😉

Nobody ever argued with you in THIS thread - that this part number/heatsink isn't right 🙂

if anyone is still monitoring this thread.

i did a 2x X5650 upgrade on Dell T5500 with a bigger heatsink and all

and here is what my dilemma is. 

before i had 2x E5620's in there with 9x 4Gb DIMMs installed and then i updated BIOS to 

A16. no problems so far. got the X5650's installed them and T5500 posts but with an error

that 2nd DIMM on the riser has an error on it.

tried with three new, identical DIMMs and the error is still there.

if i put the E5620's back in the error goes away.

anyone experience this before?

thanks

I've upgraded T7500 from 2x X5570 to 2x X5650 + 12x8GB - no problem at all.

X5650 have memory controller built-in ... so it looks like something is wrong with one of the new CPUs ... can you try and swap them ?

And/or test them in single CPU configuration ??

yes,

that's what i am doing tonight.

i will try to swap them first to see if i get an error on the other memory DIMMs

and then just put them in single config.

it is just really weird a CPU would cause one DIMM slot to not function.

thanks for your reply!

Like I said - memory controller is integrated inside the CPU.

You can also try to clean contacts. And maybe take a closer look at the CPU socket.

And good luck 🙂

Stepping and CPUID must match exactly.  They have identical CPUID

Ram speed changes for the Faster processor due to faster FSB.

Turbo Boost mode is 266 MHz for 6, 5, 4 or 3 cores, and 400 MHz for 1 or 2 cores.

Turbo Boost mode is 133 MHz for 4 or 3 cores, and 266 MHz for 1 or 2 cores.

SpeedStep,

not sure what your point is, i already know all that

and i do have TWO identical E5620's and TWO identical X5650s.

the problem is when both X5650s are installed 2nd DIMM on a riser board (daughter board) is reporting

error. when both E5620s are installed there is no DIMM error.

@Robinet,

I opened the machine, pull out the riser where the CPU was mounted and ran it in one cpu config
and everything seemed fine. so then I swapped the cpus and ran it in one cpu config and it ran fine.

at this point i am confused since the CPU i thought had an issue was working fine in 1st CPU socket
so i figured you must be right, it must have been a contact or piece of dust or something like that.


I installed the 1st cpu in the riser slot, which was giving me issues but this time it didn't report any problems and errors.   emoticon.Yes.title

thanks for your input and thoughts
