I5-2500K & compatible RAM?

[orestesdd]

I will build a computer using i5-2500k, but I selected RAM DDR3 running at 1600Mhz, but Intel says the following (See this at Intel website):

Max RAM: 32GB
RAM type: DDR3-1066/1333
Max RAM bandwidth: 21 GB/s
ECC Memory Supported: No

Thus, if I understand correctly this type of RAM, DDR3-1600 will not work according to Intel. Am I wrong? Or am I not understanding what Intel says? Please, let me know and thanks. (By the way, I will be using a Gigabyte GA-Z68X-UD3H-B3 motherboard). Thanks.

It will work fine just as long its voltage is 1.5volts! Ram speed can be set manually in BIOS on your motherboard.

It works!

Works perfectly, as you can see from my CPU-Z Validation. But as rolli59 said, 1.5V only (for CPU warranty reasons). Also, it will default to 1333 on first boot, but you can either change it manually or use the XMP profile.

RAM will work just fine....and 1.65 volts is just fine for the 2500k. You will find that most "advertised" 1.5v RAM goes to 1.65v when the XMP setting is enabled.

Sandy Bridge does not demand only 1.5v modules, it will be perfectly happy with 1.65v modules too. If someone tries to tell you that you must have 1.5v modules, then they are either trying to sell them to you, or they have been reading misinformation, or both! Another point to consider here, is that in your BIOS, if you head to the memory voltage setting, and enter 1.5v, the text will remain white/grey, if you enter 1.65v, it will turn yellow, and it isn't until 1.73v that it turns red, so at the moment, I'd rest assured that 1.65v modules are OK to use, and I have had this confirmed by Asus, Gigabyte and Corsair so far, as soon as I hear from anyone else, I will update this again.

Oh, it'll run just fine at 1.65V (and more, if the RAM can handle it), but everything I've ever read says that 1.65V RAM voids the warranty of the CPU because it causes the IMC to run out of spec (some have even suggested that using 1600 and above RAM itself does, regardless of voltage, but I don't put too much stock into that claim).
