Compatibility Note Regarding Current Build Question!

Pure Michigan · Dec 10, 2014

Hello! I noticed a "Compatibility Notes: The G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2133 Memory operating voltage of 1.6V exceeds the Intel Haswell CPU recommended maximum of 1.5V+5% (1.575V). This memory module may run at a reduced clock rate to meet the 1.5V voltage recommendation, or may require running at a voltage greater than the Intel recommended maximum" for this build:

I have heard from multiple members on this board that this is a very solid build and wanted to understand what this compatibility note truly means? Do I need to order/return different parts? Is this something that won't really have an affect on the system?

Thank you and please let me know!

It means just what it says.
Intel's memory controller is in the processor it is rated to run 1.5 volt memory running higher voltage could in long term hurt the processor.
I always recommend using 1.5 volt memory even if you lowered to 1866 MHz memory at 1.5 volt you would see no difference in a gaming PC.
If your running very high memory intensive programs then the faster memory would help.
In my PC I'm running 2133 memory down clocked to 1866 with 8 timings @ 1.58 volts.
So really up to you if you wish to use that memory or switch to 1.5 volt odds are you will need to upgrade everything again long before you will ever see any problems.

Hey Zerk, thank you for the response. I am very inexperienced when it comes to PC building/understanding the hardware as this is my first build and I don't completely understand your explanation:

running higher voltage could in long term hurt the processor - How do I determine the voltage I am running at?

I always recommend using 1.5 volt memory even if you lowered to 1866 MHz memory - Would this involve purchasing different memory? How would I lower to 1866 MHz?

In my PC I'm running 2133 memory down clocked to 1866 with 8 timings @ 1.58 volts - I am unsure how this is done

Sorry if this all seems elementary to you but please let me know the answers if you know

After looking at your build I would change a lot of it.
You would loose the SSD (this can be added anytime in the future It don't help gaming) but upgrade you to the top of the line processors and motherboard. SSD's are funny if you never had one then their nothing to miss but the fast boot time.

That cheap WIFI card is cheap If your not really far from the router these work a lot better of course a direct line is best. I use these in my house and never had a issue. http://www.newegg.com/Product/Product.aspx?Item=N82E16833704165

To use that memory and get it to that speed you will need to run the memory @ the voltage it recommends you might even need to bump it up a tad to get it stable.
For what I'm running my memory it took me about 3 days to get it their not for beginners really. It took a lot of tinkering with the timings and volts to get it stable.
