Please advice.

I just bought a Kingston 4gb 1333mhz ddr3 yesterday for my AsRock G41M-VS3 R2.0.
When I turned on the computer, nothing happens just black screen. No sounds from the mobo. Is it a faulty RAM, RAM not supported, or do I need to tweak some settings.

What CPU do you have ? Because no all the CPU can support 1333MHz. And if you use the FSB1333-CPU then you need go to the manual (page 21) to see how to set the jumper.

My CPU = Intel Pentium E6600
I tried setting the jumper and still the same.

What happens if you put the old one back in?


If I put the old one back DDR3 2g, system runs normally. If I put both in or only the 4g, then nothing happens.
Btw, if it matters, my DDR3 2g = Kingston KVR1333D3S8N9/2, my DDR3 4g = Kingston KVR13N9S8/4.

Are you running 32 bit windows?

When you mix the different RAM together, if they work then you are fine, but if they don't work together then it is a little bit tricky. You need go to the BIOS either set to 1066MHz or up the voltage a little bit ( like to 1.55V ) if you set the speed at 1333MHz, because your CPU has the FSB1066 so that 1333MHz is for OCing.

the old one 1333?= 4GB D.O.A. stick=RMA return.

I was thinking about it but this would be my 1st attempt to OC. That would mean I have to enter BIOS without the 4g ram on 1st, tweak the settings, then put on the 4g ram and see what happens, right? :p  Which voltage would that be? What would the worst scenario be... fried CPU and/or ram? :ouch:

D.O.A and RMA stands for? (sorry, I'm not fluent in English :D )

Best solution

Sorry, DOA=dead on arrival, any part that will not do anything once installed.
RMA=return merchandise authorization, Contacting where the part was originally purchased (or the manufacturer) and opening a complaint ticket.

I used to have the LGA775 and I still have it but only for the test PC now. As long as you don't go over 1.57V from the RAM specification you will not damage the RAM and the CPU. Keep in mind for LGA775 CPU you can use the 1.8 to 2.0V DDR2 RAM.

Thanks a lot. I was thinking of it too. I just want to make sure that I didn't miss any steps to make it work. Otherwise, I might get a replacement and still have the same problem with my pc due to my lack of knowledge. So base on the informations I have given, the 4g ram should have worked without BIOS tweaking or do I need to choose other types of ram?

As far as I can tell all you changed was a increase the capacity, it should have been "plug & play".

I have tried increasing DRAM voltage to 1.55v but still nothing happens when I put the 4g on. For the DRAM freq., only options were Auto/400mhz DDR3_800/533mhz DDR3_1066; I tried all settings and same result. Anyway, thanks for the help. :)

Yes. Thanks a lot. I will try to get a replacement tomorrow and hopefully it will turn out well :)
