Can't get 2400Mhz with DDR3 2400 on Sandy Bridge/LGA1155

Hi everyone!

I have a fairly old machine now (2011) with the following components:

i7-2600k @ 3.4ghz (looking to OC in the near future)
ASUS P8Z68-V PRO motherboard
Corsair Vengeance 8GB DDR3-1600 RAM (2x4GB)

I just purchased G.Skill Trident X DDR3-2400 RAM (2x8GB) and am trying to replace the old Corsair RAM with it. I've managed to do so, and I enabled XMP on my motherboard to ensure correct voltages etc., but the RAM only reaches 1921Mhz in the BIOS (/w 1.65v to DRAM).

I've installed the sticks in slots 2 and 4, not sure if that makes any difference (would have done 1 and 3 but the CPU cooler makes it difficult to use slot 1).

I thought Sandy Bridge unofficially supported up to 2400, but I went back and did some more reading and it seems like it's a bit of a crapshoot.

Can anyone provide any advice on how I might be able to get my RAM to 2400Mhz? Or if it's possible?

Ah I see, thank you - but I'm wondering why then the BIOS only reads 1921Mhz and not 2133Mhz. It seems like a very strange number, but also it's a bit puzzling why it can't make it to 2133.

Any thoughts? Any help is much appreciated.

The 3570k I believe would run the 2400 , but not the 2600k.

That is odd , it should do at least 2133.

I've managed to bump it up to 2197Mhz and it boots up, still XMP enabled and at 1.65V to the DRAM. Everything seems fine.

Does anyone know if there are any dangers in leaving it at those settings?
