Need a suggestion for 8GB (2x4) for this board.

I picked up some Corsair Vengence (CMZ8GX3M2A1600C9) and this damn thing will not POST. I get the red LED on the memory test. Tried all the memory slots and different configs of memory. 1 slot, 2 slots, single stick, two sticks etc.

New build, motherboard, 2500K, RAM and PS.

The only things plugged into the MB are the 24 and 8 pin power connectors and I am using the onboard VGA video. It powers up and reboots, powers up and reboots. Rinse and repeat. Cleared the CMOS and pulled the battery for 30 minutes.

Any thoughts?

Can you get into the BIOS at all and set the memory speed manually? Or it won't even boot to the BIOS? You could try some of the G.Skill, either the Snipers or Ripjaws.
 
Honestly, the memory shouldnt matter..... Corsair makes good memory so.....Not to suggest that it might not be bad but.....

Hopefully not a bad mobo...
 
That's what I thought regarding the RAM.

Just not sure which component to return. MB or memory to get this rig up and running.

I've got the same mobo and cpu in a system I put together this past weekend. I installed 8GB of Corsair Vengeance in slots 1 and 3 initially, and had the same problem. I pulled the memory out and started with one stick in slot 2, and it worked fine. Once I installed Win 7 and all drivers, I installed the other stick in slot 4, and all was good.

Here is the memory I used:

Wow, I didn't pay attention to the price when I copied the link. I can't belive it is that price now! I bought mine around Christmas, and with a $5 off code and free shipping, it came to $37.99.

I certainly wouldn't pay the $79.99 it's listed at now.

that ripjaw ram is a POS dude!

the samsung dimms are based of 30nm memory chips those ripjaws are probably 50nm
and they probably can't go much higher than what they are rated for while the samsungs are the real deal

i bet the more expensive kits are rebadged samsung chips

That's great and all, but why pay more for no performance gain?

I think we confirmed what we pretty much knew all along: Sandy Bridge's improved memory controller has all but eliminated the need for extreme memory bandwidth, at least for this architecture. It's only when you get down to DDR3-1333 that you see a minor performance penalty. The sweet spot appears to be at DDR3-1600, where you will see a minor performance increase over DDR3-1333 with only a slight increase in cost. The performance increase gained by going up to DDR3-1866 or DDR3-2133 isn't nearly as pronounced.

If you're looking to set benchmarking records or to compensate for personal shortcomings, K-series Sandy Bridge CPUs at least make it easy to run exotic DIMMs at blistering speeds. Everyone else can rest assured that using relatively inexpensive DDR3-1333 memory won't cost them much performance in the real world.

Sorry for the late update.

The original MB was defective. Swapped it for a different one and all is working just fine.
