RAM Question. Faster RAM = Better CPU overclocking ?

[Bipinvsnl]

Hello people of the Linus republic. 

 

I tried searching the web to get a proper answer for my question and didnt find any. So thought i ll put it up here. 

 

Now, i know that a 1333mhz, 1600mhz, 1866Mhz or a 2133Mhz wont have any noticeable performance difference. But what i want to know is, the faster the RAM the better the CPU overclocking capability ?? 

 

I am not talking about RAM overclocking. I am talking about CPU Overclocking. 

 

I have an Asus Maximus V formula with a 3570K. But only Corsair value RAM of 1333Mhz @ 16GB 4x4. 

 

I was 4.4 Ghz stable until i found out that 1 of the RAM sticks is failing soon after i started running the CPU at this speed. 

 

Now, if the new RAM sticks are Faster and a set of 2, say 2x4 G.skill @ 2133mhz. Will this help a stable CPU overclock ? Than a value RAM @ 1333mhz? 

 

Couldn't find a proper answer to my question as most of the topics seem to divert to RAM overclocking and no performance gains etc.. 

 

I just wanted to know, the better the RAM = better CPU overclocking.

 

Thanks!

RAM has no effect on CPU overclocking.

The further you push your CPU, the LESS the RAM will overclock, as more stress is being put on the CPU and its Integrated Memory Controller (IMC).

For an example, at stock, you may be able to run your RAM at 2400MHz. When your CPU is over clocked to say...4.6GHz, it may be that only 2133MHz or 1866MHz is stable.

Not really as these days RAM speeds are largely independent of CPU speeds. On older platforms like LGA1156 and 775 where RAM speed was often tied to the CPU bus frequency (because that's how OCing worked back then) you'd grab a faster kit when overclocking to increase headroom.

 

However as that's not the case anymore the difference is not really there. On Haswell using high speed DDR3 can hurt overclocking as it increases stress on the IMC (integrated memory controller) which could mean you run into instability quicker.

Thanks! This was informative.
