Asus Z87 Pro Won't Post With 2 Ram Sticks

[Meekers]

I jumped on the microcenter deal yesterday and picked up a 4770k and an Asus Pro.

The main issue I am having now is I can only get it to post with 1 stick of ram. Either of my two sticks with work on its own, however when both are in, nothing. I have tried the memok button and that does nothing. The ram is set to proper speed and timings in bios and I am putting it in the slots specified in the manual.

Ram is Corsair XMs3 2x8gb

My main question is whether I need to return the motherboard or the ram.

Have you tried to put the sticks in slots 1 and 2 (single channel) and then in slots 1 and 3 or 2 and 4 (dual channel)?

 

[Meekers]

I have not tried single channel, will give that a shot when I get home tonight. I am thinking I will likely just return the ram and order something better and hope that works.

I have a similar problem with an older motherboard and newer RAM sticks (HyperX 1600 OC). It just won't POST no matter what I try. It seems the motherboard's QVL (Qualified Vendor List) is really something to be taken seriosuly instead of just a guide line for accepted memories...

Have you used CPU-Z or the Asus utility suite to determine what RAM timings it is actually using compared to the specification? You could try manually setting them one count slower to see if that helps.

....and double check the voltage. Maybe bump it up a little above spec.

+1

so..what happened?

 

[Meekers]

Will not boot in any configuration with both sticks, slightly higher voltage and looser timings did nothing.

Newegg had a faster ram kit on shell shocker for $30 less than my current kit today, so I picked that up and will return the current ram to microcenter.

It may not be the RAM...
In fact,It's probably the mobo or chip;especially if it boots with 1 stick in each slot.

I'll find out in a couple days. Worst case I have to RMA the motherboard, but at least I will have saved money on the ram.

So I just got the new ram and the computer boots up now.

Ok..problem solved

but....why

 

[Kenmitch]

but....why

Ram compatability. Doesn't happen all the time but does pop up from time to time.

Magic, really. It's all witchcraft at the end of the day.
