Memory Showing Slower Than Rated

Arelem said:

I installed it in my Gigabyte X79-UP4 motherboard (Rev. 1.1 with BIOS F7) using their instructions (slots 1 & 2 in bank 1, slots 2 and 4 in bank 2). Their manual and website both say the Rev. 1.1 board can handle 2133Mhz memory. Its the fastest it can take.

The only thing I can is the boards I've used 4 modules on needed them as a pair in Slot 1 and 3 and a pair in Slot 2 and 4. And for best performance it helps to set the BIOS as Dual-channel. The boards I've installed came set by Default as Single-channel, same for OEM machines that had only 1 RAM module, adding a second or more required the change to Dual-channel. Also, memory will work only at the lowest speed modules installed, matched pairs always best.


EDIT: didn't see the previous post in time.

Silly me for not knowing that "supported memory" meant that the upper end ones were considered "overclocked". I would have never wasted the money on the 2133 and bought 1600.

Sorry, that bit of sarcasm was aimed at Gigabyte, not anyone trying to help me.

Your ram is at 2133, the speed shown in your cpuz needs to be multiplied by 2 for real speed

That's what i am thinking to 2x 1056=2112 his blck needs a slight Bump

You do know its 1056 X 2 right? So 2112mhz effective

Sorry for repeating g everyone im using the tablet app I only saw the cpuz post , must look closer 😂

Will need to keep an eye on bclk upping it could cause pcie to drop to 2.0

I have never done benchmarking before, never had a reason to.

I've never really had the reason to use CPU-Z before, either. I didn't know you needed to do that for the reading. I thought it was supposed to read what the memory rating was.
