RAM questions

post #1 of 18
Thread Starter 
Since I plan to use an i7 2006k with a SB motherboard, I have a few questions regarding these and the RAM sticks before buying:

1) i7 2006k doesn't support triple memory channel, right?

2) Is there any noticable speed difference between 1333mhz, 1600mhz and 2000mhz RAM(s) ?

Is it cheaper and effective to buy 4 x 4gb Corsair 1333mhz RAM sticks and set them at highest timings?

These RAM sticks (no heatspreaders) will allow me to install the D-14 cooler without any problem.

Orginally, my build included H70 and 4 x 4gb 1600mhz Corsair Vengeance sticks. These sticks have heatspreaders, so the D-14 won't fit... that's why I went for H70.

However after Reading reviews, the D-14 outperforms H70 both in performance, quietness and cost. I plan to OC my i7 2006k, so I dunno.

Help, thanks!

1. no
2. in actual world application the difference is neglect is like 1-3% difference not worth the premium if you looking for bang for the buck.

The corsair should be fine just that 4 DIMM overclocking will be harder to achieve compare to 2 DIMM with more voltages on the IMC in the motherboard.

but you just said that there's barely any speed difference, so why bother overclocking them?

Overclocking the CPU depends on also overclocking the RAM with it. I have also heard using more sticks makes the northbridge work harder and thus limit your overclock.

I think I am right, but dont trust me 100%. This is just what I have heard.

huh? people from hardforum.com said that when you overclock a i7 2xxxk processor, the RAMs won't be touched in that regard. In other words, zero speed difference between the 1333mhz, 1600mhz or 2000mhz ram sticks and an overclocked i7 2006k processor...

sigh, now I'm more confused...

impossible. Changing te bclk, you'll get higher clocks for ram and processor.
To keep stock mem clocks, just change the cpu multplier instead of bclk.

thats right,they wont be as theres no fsb increase,only multiplier.It might be heavier on your nb but should'nt be that much of an issue,people overclock with all ram slots full,unless you going for a world record or something i would'nt be concerned by this at all.

I'm still confused lol. Are you saying that it's worth it to overclock the RAMs, even if you have an overclocked i7 2006k processor? How is overclockihg the i7 2006k gonna depend on the RAMs? I keep getting different answers...

And my questions aren't still answered... Is it worth it to have 1333mhz RAMs and set them at highest timings (is that considered as overclockihg too?). Remember my processor is gonna be i7 2006k.

I have always found tighter timings lead to better performance, so if the choice is 1333 at cas7 or 1600 at cas 8, the 1333 will perform better.

On ocing the RAM: With a 2600k, you oc by upping the multiplier, you leave your blks alone. This is why the RAM oc is independent of the CPU oc on the P67 platform.

Sorry, I don't understand. People from HF told me differently... the RAMs are not dependent on an overclocked i7 2006k processor. In other words, they said that if you overclock an i7 2006k processor, you won't gain any increased speed from the RAMs... because the 2xxx series have different rules, they aren't like i7 / i5 core series...

So what's going on? Can someone else please fill me in?
