Samsung R60Plus and VS4GSDSKIT667D2

Hello all!

 

I was hoping someone would be able to explain something. I recently bought the VS4GSDSKIT667D2 kit for my Samsung R60Plus as recommended by the Memory Configurator on the Corsair website. Just to make sure I also check on other brands websites for the same model of Laptop and they all show the same type of memory upgrade modules.

 

I currently have the original Samsung 2 x 1GB 533Mhz modules.

 

I installed the new Corsair 2 x 2GB modules and the laptop did not boot. It did not go into the bios. I then tested the modules one by one and with 1 x 2GB, the system booted and working 100%. I also did Memtest and they worked.

 

I then checked for a BIOS update and I already had the latest version but flashed anyway just in case something was corrupt.

 

The only thing I can deduce is that the 667Mhz modules require more voltage than the laptop can give and therefore fail. Am I correct in thinking this? And if so, then why do Corsair recommend the 667Mhz modules for this laptop if they don't work...

 

Any help would be appreciated.

On some model notebooks you'd be amazed at how much force you need to apply to get the module to fully seat (usually the back one). If both aren't fully seated you'll only see one of the two modules. If both modules aren't fully seated the PC won't boot.

When it did boot with just one module installed did you load setup defaults in the BIOS setup?

And I would install just one module then run CPU-Z in windows and take a screen shot of the SPD tab. Then shut down and install the other module and compare it to the other CPU-Z screen shot of the SPD TAB.

Well this makes no sense... here are my screenshots, maybe you can make some sense of it. Looks like the only difference is that the old samsung is 5-5-5-15-20:1T and the new corsair are 5-5-5-15-18:1T. Yes I did load BIOS defaults.

Yes it does make sense to me the Command Rate needs to be set to 2t I would check with the NB manufacturer to check what is set in their reference BIOS.

Neither of the memory modules have this specified in their SPD and that is most likely why the system is not stable when you have both modules installed.

Also I would strongly suggest not mixing these modules they are not the same.

Thank you RAMGuy. I have looked for information regarding the BIOS of this particular laptop and I can't find anything. All there is the latest BIOS firmware, which I have already applied.

 

Also I am not mixing these modules. I have 2 x 1GB of the Samsung and 2 x 2GB of the Corsair. The screenshots show the 2 x 1GB of the Samsung working. The 1 x 2GB Corsair is all I can manage because the system won't boot with 2 x 2GB Corsair.

 

Anything I can do? Perhaps a different memory kit?
