So I have a HP N54L Gen7 Microserver with 4Gb of ram, 2x2Gb Corsair XMS3 DDR3 working perfectly,
Today I tried to upgrade the memory to 8Gb using 2x4Gb Teamgroup but the system doesn't boot up.

The MB has 2 memory slots.

The old memories work in pair or independently.
The new memories work if I use only 1 memory, but if I put both the system doesn't boot.

I think this way it will be easier to explain:
Let's call the new memories 2x4GB memories A and B.
If I use A only the system boots (4gb)
If I use B only the system boots (4gb)
If I use A+B the system DOESN'T boot (should be 8gb)
If I use A + one of my old memories the system boots (6Gb)
If I use B + one of my old memories the system DOESN'T boot (should be 6Gb)
So basically B only works by itself.

Unfortunately I don't have another system that uses DDR3 memories, so I can't test them in another system, BUT looks like one of the 4Gb memories has a WEIRD fault.

Any ideas what an I missing or what could be wrong?

EEC ram?
Is the new ram eec

Or do you mean that one of the sticks is faulty?try memtest maybe:)

Not ECC, regular DDR3

I didn't try memtest, because I never found it to be very reliable, might give it a go again.

It is really weird that one memory works ok in pair or by itself but the other one only works by itself, as soon as you any another one together, the system doesn't boot anymore.
 
4GB (1x4GB) Standard/8GB Maximum, using PC3-10600E DDR3 Unbuffered (UDIMM) ECC memory, operating at
max. 800MHz

Found this on the HP site
Seem to remember i had to get ECC ram when i upgraded my N54,also i have seen that `sometimes`the modded bios is required.I have done this too
Sorry cant be of any more help

Memory Type PC3-10600E unbuffered DDR3 ECC operating at 800MHz
Standard 1 GB (1x1GB)
4GB (1x4GB)
Maximum 8 GB
 
Can't really help with you issue but I have that proliant with 16Gb (2x8) I used corsair vengeance LP 1600Mhz, no special bios, so I guess your particular RAM is not compatible.

CML16GX3M2A1600C9

Works a treat

Actually is mine an N40, god I don't actually know......how embarrasing :D Looks like the only difference between the two is clock speed, so probably still relevant.

You could try an put one stick in and set the speed to the lowest available, perhaps up CL then add the second stick, see if it is a speed timings thing that the chip can't handle the load of two sticks at its default timings?
 
Some older DDR3 systems like P55 have issues with high density DDR3 modules that don't exist post 1st gen, since your Turion is a similar age, that might be the issue with the Teamgroup modules. How many memory chips do they have?

You can't change memory setting on the bios.

They have 8 memory chips on one side only.
But the main problem is, one of the Modules work by itself or in pair with my older modules while the problematic module only works by itself, as soon as you put any other module with it, the system doesn't turn on anymore.
