I have a ASRock N68-S with 4GB of DDR2-6400. It has 2 slots for ram but I can't use the one father away from the CPU cause when I stick the other ram stick in it beeps but will not post. Why is this?

More about : 4gb

Are you trying to install matched memory or 2 different models? It is possible that the second stick of memory OR the slot is defective. If you swap the sticks of memory, does it still work with only one stick installed?

It will work if only 1 stick is installed in the other slot(currently have the other 2GB stick in it) and it was a dual channel kit so they are exactly the same. And they work fine together cause I tried them in another PC. Its just if I try to use dual channel or stick one in the other slot only by itself it also won't post.

I would recommend that you update your BIOS if you are not running the most current version. I would also recommend that you verify that your BIOS have the memory settings set to AUTO.

If neither of these help. Double check to see if any foreign object may be in the memory slot. If so, remove it.

If all of this fails, you may simply have a defective memory slot.

Have you tried removing both 2 RAM and putting only 1 RAM in the assumed defective one? If you hear RAM error beep at boot up then it is a defective for sure.

If you have tried checking both memory by using 1 memory at a time then 1 in other, then it should confirm whether the slot is working fine or not. And if it works fine, then its not defective.

no I tried both sticks at different times in the working slot but neither work in the other slot in dual channel(both sticks in) or single channel(only 1 stick in the bad slot).

No. Don't try both sticks at a time. Use 1 stick in one slot, then use remove and use the same in other slot. This way, you can find out if there is any defective slot.

Yes that is what I have been trying to tell you all I already did that same thing with both sticks and different times but not both in at the same time. And whenever I stick ANY DDR2 stick by itself in the problem slot I get no POST.

Then it's a defective slot for sure. Either skip using the slot or replace it is under warranty period.

My advice for you to wait.

4GB RAM is enough for you now.

Get some job. And my wish for your dad too, so that he can get back some job. Never loose heart. :)

Before declaring the slot bad, revert your CPU back to stock speeds and try again with the memory installed.

Overclocking can cause some very odd issues from time to time and memory issues are very common amongst those issues.

Yes as I found that out I tried it and that didn't work either so I also tried underclocking nor did that work.

That is what I said. Defective slot.

Better don't be panic about it. Stay with current memory. This is also fair enough.

yea I know:)  I tightend the timings and the RAM module is OC's cause my CPU is(they are locked in the BIOS) and that helped the speed and get rid of the lag I get sometimes in memory intensive stuff.

I do have 1 more question. Would it be possible to have 6GB ram in 4 slots? like a 2x2gb and 2x1gb?

You can. But the 1GB will mean no more better.

Yes you can run with a such a config. Just make to match the memory modules in the correct slots in order to maintain dual channel operations.

Also keep in mind that your entire memory will throttle down to the slowest memory in your system.
