Does occupying all the RAM slots reduce overclocking potential? (on P55 platform)

[deanx0r]

I am putting a new computer together (i5 750 + Gigabyte UD2) and I am undecided between using 4x2GB sticks vs. shelling some extra cash for 2x4GB sticks.

I currently have an E6600 with an Asus P5B Deluxe, and I remember that back in the days, occupying all the memory slots would limit the overclocking potential of the board. Is it still the case? or can I just use 4x2GB sticks?

It will always be the case, unless the laws of physics change.

A friend just went from 2x2GB and reached 3.2GHz (400 FSB) no sweat but when they went to 4x2GB they had the hardest time breaking even 3.0GHz (375 FSB).

How much does having 4 sticks versus 2 sticks affect a potential OC? I'm sure it's a case by case thing but is there a consensus on a general number? Like 5% less OC? 10%? Where is extra tweaking necessary to reach the same OC?

It's always a factor as mentioned, but less of a severe one than in the past.
I'd say from what i have seen & have experienced you'll be fine going with 4x DIMMs.

My system in my signature is held back by my CPU, not board or RAM, as an example.


KingstonU, it really varies depending on motherboard, & especially for chipsets like P45, the overclocker's skill with fine tuning settings like GTLs, etc.
Running with all DIMMs populated & wanting a strong OC is going to frustrate a good number of less savvy OCers i would say, as a lot of patience & willingness to tweak can be required.

thats why u even see the high end ocers only bench with 2 sticks out of 3 on X58 platforms even.
