I currently have 2 gigs of crucial ballistix PC5300 ram on my gigabyte GA_965P_DS3P mobo.

When I first built the PC I put 4 gigs in but memtest failed 2 gigs. I RMA'd that for 2 more, they failed, RMA'd them, but they failed too, so I got a refund.

Now I just got 2 more as I had some spare cash and on vista 64 again.

Anyway, I put the two new ones in the same dimms as my current working ones and they test fine on memtest, as do my original ones.

Then I put all four in and theres errors.

So I try pairs on their own.

One pair fails in any 2 dimm slots, even swapped around. I just put my originals back in the and they test fine.

So eventhough the new ones tested ok once, after all 4 are in, a pair die.

So I've kinda kill 3 pairs of ram from putting 4 gigs in my board.

WTF?!?!?!?! is my mobo killing a pair if I put 4 gigs in or is it dodgy ram?
 
Do you have the memory voltage set to the manufacturers recommended setting. Some boards under volt the ram @ default and this can cause problems when you add more sticks ie 4.
 
Well when I first did it I never touched the BIOS.

Now im overclocked and have set +0.2v. In my BIOS it doesnt actually show the voltage its set at.

So even at stock volt and added volt it doesnt work.

But these other two sticks are dead, as they wont test even on their own, so I gotta RMA them.
 
Do you recon that other rams ****** now though as it fails memtest? but it didnt on its own in first test

Hmmm...I was considering getting another pair of Crucial Ballistix for my machine too. I hope you get yours sorted/find out what the problem was.

By the way, my PC didn't get past POST at +0.4V (2.2V). I ran mine at 1.8V with no overclock and now running at 2.1V with current overclock.
 
No I don't think your new set is faulty, the ones you rmaed before were probably fine either. Some mobos can act very weird with 4gb, mine BSODed even though memtest ran overnight with no error. I've increased both RAM and northbridge voltage and now it's fine.

Try increasing the northbridge voltage as well and try +0.4V on the RAM as suggested before.
 
ill have to give to my brother to try, but I ran the 'suspect pair' about 5 times in different positions and every time its failed, since putting all 4 in at once!
 
Mybrother can not test it so im a bit stuck there.

But each time I RMA'd it they sent new, so there must have been problems with it after I had it.

So im assuming its dead and the mobo kills 2 gigs each time.
 
I have a similar problem with 4 gigs of ballistix and a gigabyte board - any 2 sticks work, 4 will not.

Yes it's at stock (1.8-ish?). How exactly do you change that? Is it the overvolt option in the BIOS?

Is the ram no good after if you test it in memtest?

I haven't used memtest - heard too many problems with it, it seems very unreliable. Any combination of two sticks of the memory works fine, just not all 4 together - the board has known issues with filling all 4 DIMMs - they released a BIOS update to help with all 4 DIMMs but of course my system would not POST after the BIOS update.

I'd say all that memory you keep returnign might be ok, it could be just be the board doesn't like all 4 DIMM's being populated.
 
Its just odd that to start with they were fine untill I plugged all 4 in, now wont pass a test at all.

The system recognises all 4gigs, but when I first loaded the OS from new I had loads of issues. Found this dodgy ram in memtest, took it out, reinstalled the OS with 2 gigs and all was fine.

I could just install on the 2 gigs now, get it all running and the plug in the other 2 and ti will register 4gigs, but then I may have instability issues.

I flashed my BIOS to the latest, but cant remember what this was, so dont know if theres a newer one, think it was F5.
 
I've given up trying to get Asus Maximus and 4 x 1GB Crucial Ballistix stable, all sticks work fine paired but put in 3 or more sticks and it would never pass any stress test, I must have tried everything to try and rectify it to no avail. Now I have a Gigabyte board and 2 x 2GB OCZ. :p

It seems to me that the latest Intel chipsets are like chocolate fireguards with 3 or more DIMMS installed.
