Mac Mini 2011 three beeps - tried many things

Good afternoon.

I've got Mac Mini 2011 2.5GHz the one with Radeon GPU.

Things what I know about it.

It started making 3 beeps - pause - 3 beeps and so on.

I know from Apple website it is RAM related problem.

I've fully disassembled it - no liquid damage - brushed RAM connectors with isopropyl alcohol. Assembled correctly (as I know something about Mac repairs).

BIOS battery removed and put back in.

I've tested with 2 other RAM modules - and one module at time - in upper and lower slot.

When no RAM modules in - just one beep.

No success - just those beeps and fan full on.

HDD is working and spinning when power on.

Thank You :)

Well your error condition implies your RAM is bad or the wrong type for your system. Did you upgrade your RAM? About Mac Power On Self Test (POST) RAM error codes.

I've tested with 3 other RAM modules 1066MHz and 1600MHz (I know it is only 1333MHz - but I know they are working with those speeds as well)

And my modules are 100% working

I've tried to put one module at time - to each slot - no difference

When no modules at all - just one beep :(

Sorry guy ;-{

The RAM slots must be damaged then. You'll need to have the logic board repaired or replaced.
