1.65V RAM with a z68 and i7-2700K CPU ok? Help

Last response: in Memory

I just checked out the recommended RAM on my motherboard's memory list and it has the Kingston Hyper X memory at 1.65V as an approved memeory. I read that Sandybridge CPU's don't like anything over 1.5V. Is this true?

I'm planning on ordering 16GB (4GBX4). Can someone tell me if this is definitely NOT good? I'm trying to use a low profile ram to clear the Hyper 212+ CPU Cooler.

Mother board is the Gigabyte Z68X-UD3H-B

Memory List:
http://download.gigabyte.us/FileList/Memory/mb_memory_g...

Here is the one I am considering:
Kingston HyperX 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model KHX1600C9D3K4/16GX
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Also read that some z68 mobo setups prefer only 3 of the 4 dimm slots full. Is that true?

Will this memory be fine? I might want to OC the CPU a tiny bit, but nothing crazy. Will this memory cause issues?

Any tips appreciated

Well, it is not recommended, it voids warranty. 1.5v is the one u need.

Best solution

Get this RAM, CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CML16GX3M4A1600C9B

I recommend CORSAIR Vengeance, quality RAM and low profile with XMP profile.

And if u will get an aftermarket CPU cooler, low profile is the worry free remedy with perfect fit with any large cooler.

Vengeance Low Profile heat spreaders have a reduced height of 1.03" (26.25mm). They're designed for high-performance systems with extra-large CPU coolers, small form factor system builds, or any other space-constrained application where standard Vengeance memory might not fit.

Hi there,

I have a 2600K and the same RAM I recommended for u.

Running easy @ 4.5GHz with Frio cooler, but I also recommend the one u have chosen : ))

I build 1 PC with that cooler and it OC'd without problem as well and it cooled fine too.

Thanks Nikorr,
I have been considering the black version of these, but they weren't listed as a compatible chip so I was steering away from them. Think they will be ok even if they aren't listed on the compatible memory list? I'm guessing they probably are, just wasn't sure if I should definitely stick to something on that list to be safe or not.

For the builds you did, were they z68 boards?

Mine is ASUS P8Z68 V.

other was P8Z68 V LX and ASRock extreme3 series.

The black version is just as good : ))

It is OK, most RAM sticks never certify to be on the list,

as companies wont pay the cert fee's : ))

Thanks Nikorr, you have me sold on the Corsair. Something in my gut told me to go with this from the start.

The white version runs at 1.35V where the Blue's and Black's are at 1.5V. Is this cool or would it pose any issues later? I like the white color.

Both 1.35V and 1.5V are good.
February 22, 2012 3:41:19 PM

Is it possible to run 2 chips at 1.35V and then 2 chips at 1.5V? Do motherboards typically allow that or not really? I probably won't do this, I'm just trying to decide if I want to buy 2X4GB=8GB and then possibly throw in 2X8GB later, or just buy 4X4GB now.

Well, these Special Edition Arctic White Vengeance Low Profile memory modules operate at the ultra-low voltage of 1.35V, for ultra-quiet systems and other low-voltage applications.

In most cases they will run fine too. But the sweet spot for the SB are the 1.5V ones : ))

If u understand how to tweak the system than go for it, and I would get the 16GB, its so cheap now, I would not think twice about it.

I just like the white color but don't have to have it if the system would run better at 1.5V.
Is 1.5V better with the SB chip?

Would 1.35V leave more room for possible upgrades later? Could the 1.35V be run at 1.5V if required safely if it is more stable for the SB system for whatever reason?

Sure u can, but if u run into issue, you must be able to readjust the voltage in the BIOS.

Looks great.

February 22, 2012 4:19:28 PM

Sweet!!! ordering up 16GB! My build is complete! Everything arrives tomorrow, very exciting!! :) 

EDIT: Saw a post or two about someone with the same board that had to bump it up to 1.45V to run stable. I'm going to just get the Black's or Blue's instead.
Thanks for all the help!

I ended up going with the 1.5V ones you originally mentioned. I ran each stick individually for 7+ passes in MemTest86+, and then all 4 together for 10+ hours and they ran perfect without any errors. Great chip, great recommendation, thanks!
