Z77 / DDR3 voltage compatibility?

[Borealis7]

Hello,

i am currently researching an Ivy Bridge build and i was looking at a M/B by GIGABYTE called GA-Z77M-D3H (http://il.gigabyte.com/products/product-page.aspx?pid=4142#sp) when i saw this line:

"4 x 1.5V DDR3 DIMM sockets supporting up to 32 GB of system memory"

which got me a bit worried since i planned on getting these DDR3 sticks:

CMX8GX3M2A1600C9 (http://www.corsair.com/cmx8gx3m2a1600c9.html)

which say: 8GB XMS Memory kit for dual channel systems, 1600MHz, 9-9-9-24, 1.65V

now, i'm not set on getting these exact parts, but is this something that could be problematic when putting together a build? do i have to get 1.5V DDR3 sticks for such a M/B?

thanks.

Worst case scenario, it will default to 1333 Mhz @ 1.5v. But, you can also give Gigabyte a support ticket, to double check that (they normally respond within 48 hours). This board offers voltage control for memory, so most likely, you're going to be fine, though.

Get 1.5V. This is not a motherboard problem but a CPU problem so to say due to the memory controller. And plenty of 1.5V options out there.

Warranty is void on the CPU with anything over 1.575V.

Get something similar to this instead:

And what does that have to do with the CPUs memory controller voltage limit for warranty?

The SPD on that memory also says 1.5V 1600Mhz. Go figure.

I run my DDR3 2400 at 1.65v

I did run 8gb ddr3 1600 corsair xms3 cas9 1.65 with SB for quite some time, it did cause issues like lower oc etc

My 2500K would easily do 5Ghz with 2133 memory

you wanna sell it ? :whiste:

Sold it a long time ago

Sold it a long time ago

is there a noticeable difference between the two?

Not really. Better single threaded performance

In your opinion, do you think it was worth it?

Depends on what you want. I love having the latest and greatest which is why i bought it. If you can't afford to spend 220 on a new processor and have a 2500K just stay sandy

I'd love to have either platform. Still happy on this electricity guzzler system.. maybe i'll fall to a GTX 680..
