have had this board for a year now. but I think the problem has been on going for a good portion of that time. anyway it seems if I slap in only 1 stick of ram at a time every slot causes the board to beep rapidly and fail to boot on all slots except the 4th slot

if I put all 8gb of sticks in of works but fails in memtest. within the first pass.

any ideas what's up?
 
does it matter which ram stick you use?

Probably a dead/dying board or you need a bit more voltage to stabilise it.

And I've tested every RAM stick individually they pass memtest with a good 5+ passes. They all work provided one is occupying the 4th slot.

Currently I've gone back down to 4GB (slot 2 and 4) and it passed memtest (only 2 tests)
But when I put all 4 sticks in it insta fails on memtest despite each one passing individually. Don't get why slot 4 is the only fine one alone though and it's most probably got something to do with the kernel-power 41 BSOD/ Freeze and crashes I've had for a good while lately =/
 
I've got this board - had a slightly embarrassing (and reasonably expensive) RMA experience with it when I first got it. Similar issues to you - couldn't get the board to boot.

Turns put the board is quite selective of which RAM stick goes where - so it would only boot when RAM was in slots 2 and 4 (if memory serves) - so it only booting when in slot 4 sounds like the norm for this board.

I think I eventually found a thread about it on the Tweaktown forums. Might be worth having a quick check there if you're uncertain.

As for not doing the full set of 4 - what voltages are you using for the RAM and the IMC?

All the best,

Will check Tweakdown later, hopefully got some helpful info on it.
RAM is at 1.584V atm and VCore is 0.992V atm but that's cos I set mobo settings back to default so it's auto-tuning it.
 
That's a pretty poor mix and match.

You've got one set of 1333MHz, 9-9-9-20, 1.55-1.65V RAM and one set of 1600MHz, 9-9-9-24, 1.8V RAM.

You'll need to find the lowest common denominator at which both sets will work.

I suggest you try 9-9-9-24, 1333MHz and 1.65V and hope the Patriot will run at the lower speed with lower volts.
 
Doesn't really matter atm- I've kept only the OCZ in atm and I still experience the kernel-power errors and the pair failed in memtest but pass when alone on slot 4. =/
