RAM upgradation query

[Lordofthejinx]

Hi,

I have MS 7613 Inverness Motherboard. I was scrolling through the specification and came across this.

• Dual channel memory architecture
• Two DDR3 DIMMs (240-pin) sockets
• Supported DIMM types:
  • PC3-8500 (DDR3-1066)
  • PC3-10600 (DDR3-1333)
• Non-ECC memory only, unbuffered
• Supports up to 8 GB on 64-bit systems
• Maximum memory only if using 4GB DDR3 DIMM modules

I have DDR3 1600 with me and would like to use it. I have tried seating it but the system doesn’t boot and runs into a restart loop. I guess the motherboard should step down the memory speed to the maximum it can support but this doesn’t seem to be the case. How do I resolve this?

Hi:

The fastest speed the Intel H57 Express can run the memory at is 1066 MHz (PC3-8500).

Normally, memory can only go back one clock speed, and PC6-1600 would have to go back two clock speeds.

Also, PC3-1600 memory can come in two voltages...1.5V and 1.35V.

If the memory module you have is 1.35V it won't work.

Your PC must use 1.5V DDR3 memory.

Actually, I was incorrect.

The  Intel H57 Express can run memory at 1333 MHz, so that wouldn't be the reason the 1600 MHz won't work.

I forgot that it is only the notebook versions (Mobile Intel series 5 chipsets) that can only run the memory at 1066 MHz.

If it is 1.35V, then it won't work, or if it is not a low enough density, it won't work.

I use this memory in desktop PC's with Intel series 4 and series 5 chipsets...

The label on the RAM says DDR3 1600 and also mentions the voltage ratings as 1.35/1.5v 

I am sure that both the RAM slots are working fine. 

The specification for the mobo also says: 

• Maximum memory only if using 4GB DDR3 DIMM modules
  I have a feeling that this could be the culprit.
  
  Below is the item code  of the new RAM module i am using 
  

DLD8GD3-16 8GB DDR3 1600 16C (PC3-12800) Long-DIMM

Does it have to do anything with the BIOS version? I am sorry if this is a silly question.

Hi:

Thanks for posting the specs of the memory.

The reason it doesn't work is the maximum memory per slot is 4 GB, and the memory module spec you posted is for an 8 GB memory module.

The motherboard your PC has can only take a max of 8 GB (2 x 4 GB).

The chipset your PC has can handle up to 16 GB of memory, but in order for that to happen, the motherboard needs to have 4 memory slots.
