Solved DDR3 1333MHz Ram Incompatibility

August 13, 2012 at 23:44:18
Specs: Windows 7 Ultimate SP1 x64, Windows Server 2008 R2 SP1 x64
Hello,

I was wondering if you could assist me with a problem I'm having.
My computer originally had (2x2GB=)4GB of RAM.

Since day one I've gotten all sorts of memory-related BSOD. As a somewhat-beginner with hardware, I realized that the RAM was bad.

I took out one of the sticks and BSODs were gone for quite some time. I'm still getting some, but not as often as I did when the second one was attached. I ran several tests, including "Windows Memory Diagnostic" and it detected a hardware problem.
BSOD were mainly: Bad Pool Header, Memory Management, IRQL Not less or equal.

So I decided to purchase a new RAM. And instead of purchasing 2GB stick, I decided to buy just one 4GB. When I installed the RAM, the computer refused to boot up. It beeped three times and continued to do that over and over. I'm guessing it's RAM incompatibility. But I'm pretty sure I bought the right one. Could you please help me?

Specs:
Motherboard: DG43RK (Click to access official page)
Original RAM: 2 sticks of "Infinity" DDRIII1333 2GB CL9
RAM I bought: 1 stick of 4GB Kingston KVR1333D3N9/4G.

Is it the wrong RAM? :\
Another guess is that there's a problem with installing a 4GB stick of RAM instead of 2 of 2GB?
Is this somehow related?

Thanks for your help!

✔ Best Answer
"Total 8GB of system memory supported".

Since you have four DIMM slots, that equals 2GB max per slot. Which means that
probably you can`t use one 4GB module.

And there is the same thing in the manual: Up to 8 GB utilizing 1 Gb or 2 Gb technology.

P.S. About the BSODs with your 2x2GB modules: did you run MemTest to check the memory for errors?

Thank you so much for your help.

Yes, I also ran MemTest when both sticks were installed, but it didn't find anything wrong. I let it run for 2 passes.

Before replacing the 4GB stick to 2 sticks of 2GB, is there anything else I should check?

When I entered my BIOS, the original RAM listed there was working at a 1066MHz speed. And the manual specifies that I must OC to get 1333MHz.
I have no intention of OC and I don't mind running at lower speed just as long as there isn't a problem.

Thanks again!

If your 2x2GB modules are on hand, you can throw them in and check them for errors with MemTest. If you need help to make a bootable CD from which you can access MemTest, let me know.

When I entered my BIOS, the original RAM listed there was working at a 1066MHz speed. And the manual specifies that I must OC to get 1333MHz.

1333MHz is not natively supported frequency by your MB, so by default it sets the memory at 1066MHz. It is not a problem at all. You can tighten the RAM timings a bit to compensate (according to the modules specs), but more on that later.

I'll try and run MemTest again with both original sticks installed. In the meantime, I'll also return the recently purchased RAM and get two sticks instead of one.

This may take several days but I'll keep you posted.

Thanks and keep up the good work! :)

If you have a 1333MHz FSB CPU, you should run your RAM at 1333MHz. It's not overclocking if that's the speed the RAM is designed to run at.

Thanks for replying.

I'm afraid my CPU FSB Speed is 1066 MHz.

All is well. :D
I wanted to wait some time to make sure of it.
RAM was replaced.
Thanks!
