8GB single Module RAM not working in DH67BL

[muthultech]

My system specifications are as follows:

Processor- I7 2600K @3.4 Ghz (SandyBridge)
MoBo- Intel DH67BL
Ram- 4GBCorsair XMS 1600Mhz
PSU- Cosrair 500W PSU
Graphics- Nvidia 9400GT.
OS- Windows 7 64 Bit

This configuration I was having earlier and It was working fine.

A few days back, I got some money and I wished to increase the RAM.
So I bought a single Module 8GB transcend 1333Mhz Ram. I removed the old 4GB corsair Ram and Installed 8GB single Module RAM. But when I started the system, nothing happened. Even the boot screen is not showing up. Just the monitor power LED is blinking. No kind of beep sound as usually comes due to RAM problem.

Also I updated the BIOS to the most recent version, by using the old corsair 4GB RAM. But Nothing seems to change, when installing transcend 8GB single module RAM.

But the Transcend RAM ,when I bought is a brand new one and it is sealed.

Need help on this.

Thanks
Muthu.

The 8GB ram stick might be bad.

See what happens if you have both the 4GB and 8GB ram stick installed.

The same problem happens, when I install both 8GB and also 4Gb ram. The System refuses to start.

The board supports 8GB DIMMs. Also you should always use 2 at a time.

I would guess bad memory too.

Ok Then should I try two of these 8GB modules at a time? Is it risk in spending money on other 8GB?

Start by getting 1 to work. Sounds like the 8GB you bought is faulty.

Curious why you should always use two at a time?

For optimal performance you run them in dualchannel. Else you only get half the memory bandwidth. Its essentially a relic since DIMMs didnt expand to 128bit or higher, but are still 64bit wide. On LGA1155 the memory controller is 128bit wide. On LGA2011 its 256bit wide.

You roughly get 5-10% more performance of the system when running dualchannel vs single.
