Motherboard RAM-support, AS-Rock Extreme6 and 1.5V Kingston

by DC_DK / November 11, 2010 2:00 AM PST

Greetings from scandinavia.
I just bought an i7 950 with the Extreme6 MB, I choose to pick my tri-channel RAM-blocks among the few DDR3 on the market operating at 1.5volts. Read that the memory-controller in the i7 chip can get damaged by higher voltages! RAM-Specs:
Kingston ValueRAM 3 x 2 GB - Product code: KVR1066D3N7K3/6G
1066 MHz, PC3-8500 - 7-7-7-20
On-Die Termination (ODT) / Intel Extreme Memory Profiles (XMP)
AS-Rock's MB-support page does NOT have these modules on the Compatibility list!! Now Im afraid these Kingston RAM will cause a problem, this is my first rig-build!
Help me figure out whether I should send the RAM back

Well, I read it in some articles, here are the ones i have the adress on:
http://www.legitreviews.com/article/806/1/
http://www.anandtech.com/show/2636
-The source to my consearns is actually from the supportpage on the X58 Extreme6, the modules arent in the supported list!! How important is it to follow these guidances??
I have wrote to AsRock, and am in the process of contacting Kingston. Just thought, maybe someone knew how 'hard' one should follow that DDR-compatibility list.
(Thanks for answering guys) DC

The articles said something about that core i7's integrated memory-controller could get damaged beyond repair by memory-modules operating ABOVE 1.5V. Almost all of the DDR3 triple-channel operate at 1.65V, but then I found these. Havent had the time to try to figure out, whether there IS a problem, or whether those sites(articles)are just AMD-freaks bashing superior enemy architecture Happy

You're right but

In reply to: correction:

The chipset voltage and the memory voltage are on different supplies. I supplied the link to the Tom's Hardware so you could see that in the screen shot.

I don't see the problem. But that doesn't mean people won't fret over this.

Oups !!

Just re-read those articles, and it seems I got it wrong: Its apparently only a problem when going BEYOND 1.5-1.65V -So Im going to return those Kingston, cause they are too slow!
BUT: Does anyone know how much one should follow that DDR3-compatibility list for supported modules???

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
