I5 2400 38 x?

I have been reading that the I5 2400 is capable of A 38x multiplier? I only ask because I recently acquired four of them. And I’m wondering if it would be worth it to toss one in my Asus p8z77-v lk?

Doesn’t make a whole lot of sense since they are a 3.1 GHz processor. And should do about 3.5 GHz on turbo boost. But several people have suggested that they can do 38X multiplier for a total of 3800 MHz. Some have even suggested between 3.9 and 4 GHz or even higher with a bclk increase

This is weird to me... I would think they are a 31x and 35x on turbo

Is this his bull crap?

It is true, up to haswell all intel CPUs had a free 4x multiplier bins, the 2400 have a turbo speed up to 3400mhz single thread and 3200mhz all cores load, so with the extra free multiplier it will reach 3800mhz single thread and 3500mhz all cores loaded. Don't touch the bclk, it affect everything else including pcie and other things that can cause severe instabilities.

OK so the +4 BIN is In addition to the turbo function

So I am guessing that the +4 BIN is only for the i5 and i7 not the e3-1220 Xeons?

Well I pulled my e3-1220 v2 and dropped in an i5 2400... now the settings are there... can access the +4 BIN... it will hit 3.8GHz easy... but under load drops to 3.6GHz. But I thought I could lock turbo in place to hold it at 3.8GHz
 
Sandy Bridge and Ivy Bridge non-K CPUs from the i5 and i7 series can be overclocked with an additional +4 to their turbo multipliers. This does not work with the corresponding Xeon E3 processors. The i5-2400 runs at 3.1 GHz and has the following additional turbo boost steps: 1/2/2/3 (for load on 4, 3, 2 and 1 core). This means it will run at 3.2 GHz when all four cores are loaded, and with 3.4 GHz when only one core is utilized. Adding +4 to these turbo boost steps gives you 5/6/6/7, which translates into 3.6 GHz when all four cores are loaded, and 3.8 GHz when only one core is utilized.
