Unhappy 1600 MHz on a 1060 MHz supported CPU

Hey guys. I am building my first PC build and I need some help buying some RAM...

I have the Intel DX58SO "Smack Over" Motherboard. I am running an i7-920 2.66 GHz. I have already bought 2x 4GB Kingston KHX1600C9D3K2 RAM, but I got 3 long beeps and no POST. This means, memory reseat. So I contacted Intel and they said that it is because that it is 1600 MHz RAM and my CPU only supports 1060 MHz. So I go onto Amazon.ca and buy myself some RAM 2X 4GB Kingston KVR1066D3NK2 RAM. Go the same issue. I got really fed up with this. I contacted Intel today and they said its because both RAMs are 1.5V while the CPU only supports 1.65V. So I call NCIX and they recommended www(dot)tinyurl(dot)com/3zjqepz. I had a chat with them and they said that it is a 1600 MHz RAM but the i7-920 will automatically step the frequency down to the highest supported frequency. Which made sense. I call Intel and another Technician told me that my CPU is actually 1.55V, while NCIX and the other Technician told me that it ism 1.65V. Intel said that it will work but the memory controller will burn-out after a month-or-two... I call back NCIX and they said that it will work but I just have to adjust my voltage in the BIOS down to 1.55V if necessary. NCIX told me that there is a 1% that it will not work...

So I have bought until today 4x sticks of RAM costing me over $160 + tax. I don't want to make another mistake.


It is a 1600 MHz (Which will be automatically stepped down to 1060 MHz) at 1.65V.

Please help me out guys!!!

My System Specs


That Mushkin memory should do the job. It's 1.65V mem, and meant for a triple-channel config. Both previous sets of ram you bought were 1.5V and dual-channel.

CPU voltage means nothing when it comes to RAM voltage.

It sounds like your perhaps trying to run your system with as sugar said dual channel not triple channel which is the way the 920 works.
