Hey folks, I'm in the midst of configuring a system and I'm looking at going with the Intel Core i7 2600k. I have the option of upgrading for free to 8GB of 1600MHz RAM instead of 8GB of 1333MHz RAM.

According to Intel (http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-(8M-Cache-3_40-GHz)), the i7 2600k only supports 1066/1333 memory types.

I'm configuring with iBuyPower and they are offering RAM with speeds up to 1860MHz... is there any point to going with 1600MHz over 1333MHz?

Remember the cost doesn't change when going from [email protected] to 8G[email protected], so perhaps I should just stick with the fast one for another time when I end up with a CPU that can take full advantage of it? I guess I should also ask, will the CPU be able to use the 1600MHz RAM at 1333MHz, or will it not work unless the RAM is specifically 1333MHz?

Thanks for any info!

If you don't plan to run the RAM at 1600Mhz, 1600Mhz RAM running at 1333Mhz will be able to run at much tighter timings than most 1333Mhz RAM at 1333Mhz.

That said, the 2600K can do 1600Mhz easily with just a BIOS adjustment.

2600k officially supports only 1333mhz, but you can use much faster ram. That's only whats "officially" supported. You can use faster ram just fine.

1333 is just the officially supported speed.

In reality the limit is much higher.

Thanks for the info guys. Do I need to make any adjustments to run the 1600MHz RAM at full speed, or will the CPU run it at max speed automatically?

You'll have to tell it to in the BIOS.

Set the bios to use the X.M.P profile or just choose 1600mhz in RAM Speed than AUTO.

Its more the motherboard that will determine the speed you can natively support. The Mobo manual will also list the support for overclocked speeds as well.
Motherboards do not have the memory controller on them with modern chipsets. That has been put on the CPU.

My freeway only supports 65mph, but my car goes much faster.

I recommend the latter.

XMP is often wonky and can alter voltages too much.
