2500K Memory Limitation?

[Meaple]

A friend noticed that on the specification for the 2500K and 2600K and frankly probably both them series', he noticed that it said memory types, DDR3-1066/1333. I thought it was a bit odd but never took any care or notice towards it. Could someone explain why it says this on the specification?

Thanks in advance.

1066/1333 is the native memory frequency for the CPU, it's the maximum the CPU it's self supports but the motherboard will force it to run at 1600mhz or above depending on what RAM you have 1600, 1866, 2133 etc.

This is why you have to manually set RAM timings and frequency in BIOS because 1600mhz RAM will run at 1333mhz by default.

Ok, would the BIOS automatically run or would I definately have to set it to 1600MHz manually? My friend said that in the BIOS it says that it is running at 1600MHz but he hasn't changed anything himself.

Thank you for your reply. It has helped massively.

Some motherboards do it automatically I think it depends on the BIOS. Not sure tbh I just know about the CPU part of it.

On my P67 board I had to set the timings and frequency manually.

I had to set the frequency and timings manually on my p8p67 Deluxe. It was 1333 mhz and 9-9-9 24 default.

Even a higher end gigabyte z68x ud7 runs my rams 1333 9-9-9-24 by default.Have to change it manually.But there some pnp rams that do the setup by themself.
