Hi there,

I recently purchased a new RAM (Kingston DDR3 4 GB 1600 Mhz (KVR16N11S8/4)). I already have Kingston DDR3 2 GB 1333 Mhz (KVR1333DRN9/2G) installed.
Unfortunately when I installed my new RAM, I only got a black screen. After checking if I correctly inserted the RAM the right way (heard the clicking sound), there was still no change. After reading on different forums, I realized that my old RAM was put in the 2nd slot and I put my new RAM in de first slot. So I decided to put my new RAM in de 4th slot. The black screen was now gone, but de rebooting process didn't get passed the manufacture's screen (it gave the option to press DEL or F8 for options, but my keyboard didn't respond). I decided tot change the order of the ram (so new RAM in slot 2 en old RAM in slot 4; I also did the same for slots 1 & 3) but to no avail.
With one of these combinations (can't remember which) the pc would reboot constantly after a couple of second (just black screen).

The PC starts fine if the old RAM is only installed (in all 4 slots). So there is nothing wrong with the slots or my motherboard. When I only installed the new RAM, I got a blue screen saying that the new software isn't properly installed and it may cause damage (parafrasing).

So my question is: what's wrong with the new RAM. Is it a simple compatibility problem?
(All the Kingston RAM that is compatible with my motherboard are discontinued bij Kingston (read this from their site)).

Thank you for your time!

The sticks will either play together or they won't, if placed...
will the computer boot at all just using the 4gb stick? What you might have to do is put in the 4GB stick and rest the bios, load into the bios and set the new 4GB stick to 9-9-9-24 @ 1333MHz Once that is done you should be able to add the 2GB stick.
 
also do not put the sticks in matching slots put the 4gb in A1 and the 2gb stick in b1 to run them in single channel mode. Two different ram sizes running in dual channel will play unholy hell with each other.


Like I said clear the cmos on the computer and put the 4GB stick in, when the computer boots up go into the bios and manually set the speed to 1333MHz @ 9-9-9-24 timings. Save and shut down the computer, then add the 2gb stick and boot up. This will force all your ram to the same speed and timings.

Ok cool, I still have one question. What is the cmos and how do I clear this. When I was in the BIOS earlier, I could only change the Mhz (it was set on auto and i had the options to put it at 1600, 1333 en 800 (?).). But I don't remind seeing the timing feature you're talking about....

Start with the 4GB stick in slot one closest to CPU and see it it will boot by itself....if so, go into BIOS and see what it's running at, probably 1066(533), then raise the DRAM voltage to 1.56 save exit shut down and add the older stick in slot 3 from CPU and give it a try, let us know if it starts up OK and use CPU-Z (free downloadable app) to look at the DRAM (in the memory tab) and tell us what freq and timings all are running at
 
depending on what your motherboard is it might have button on the back I/o panel or there is a jumper on the motherboard. If you still have the manual for the motherboard it will tell you in there how to clear the cmos.

Anyway if your able to load the computer with the 4GB stick get into the bios change the speed from auto to 1333MHz. there should be an option that says dram timing, if you can find it set them to 9-9-9-24. Once that is done add the 2GB stick right next to the other one, you want to force the ram into a single channel mode. Running dual channel with different size sticks will cause issues that you may never figure out.

The sticks will either play together or they won't, if placed in a dual channel mode they will run in Intel's flex mode where there will be 4 GB in dual channel and the odd 2GB of the 4GB stick in single channel. The biggest problem that may be encountered is if the will even play together, which is why I suggested slightly higher DRAM voltage, because any time you mix DRAM it can be and often is problematic, slight voltage changes to the DRAM proper and the MC is the base approach to seeing if you can get them to play, then you progress to freq and timings
