Is It Possible to Achieve 6000MHz RAM Speed with Intel i7-13700KF?

Hey everyone!

I've been doing some research on RAM speeds and compatibility with the Intel i7-13700KF processor. According to the specifications provided by Intel (https://www.intel.com/content/www/us/en/products/sku/230489/intel-core-i713700kf-processor-30m-cache-up-to-5-40-ghz/specifications.html), the maximum memory bandwidth for this CPU is listed as 89.6 GB/s.

Now, I've been trying to understand whether it is even possible to achieve a RAM speed of 6000MHz with this processor. I did some calculations and came up with a theoretical bandwidth of 96 GB/s for 2 DDR5 RAM modules running at 6000MHz, using the formula: 6000MHz x 8 bytes x 2 DIMMs = 96 GB/s.

Based on these calculations, it seems like the RAM speed of 6000MHz should be achievable without any bottlenecks from the motherboard. The motherboard in question supports speeds of up to 6600+ MHz, so that's not a concern.

However, I'm confused about the max memory bandwidth parameter listed in the processor's specifications. Does this value indicate the maximum amount of data the CPU can handle, or is there something else to consider?

I would greatly appreciate any insights or experiences any of you might have regarding this topic. Is it possible to achieve 6000MHz RAM speed with the Intel i7-13700KF CPU, considering the max memory bandwidth limitation specified by Intel? Or is there something else I should take into account?

Looking forward to your thoughts and expertise. Thanks in advance!

6000 should be fine as long as its 2 Dimms. 4 Dimms, not so much.

most decent boards will do 6400mt-6600mt max stable at 4 dimm now, assuming the BIOS is up to date.

 

This is generally with manual tweaking, but XMP is sometimes doable at 6400.

6000mt (it is not mhz) ram is right in the middle for ram speeds, 8000mt ram is actually doable with your CPU given a good IMC bin and a well-binned ram kit, at 1 dimm per channel on high end boards.

 

The max memory bandwidth is the bandwidth at the maximum “officially supported” speed listed on the CPU’s Ark product page, XMP/overclocking are not officially supported nor are speeds for it listed on Intel’s product page. The CPU is capable of significantly higher real-world bandwidth.

 

5600 is the max speed it officially supports at JEDEC, 5.6x8x2 means your bandwidth works out to… 89.6
