How good a ram do i need to overclock my i5 750 to 3.4ghz?

[ЀṾ]

Hi,

Im about to buy the core i5 750 and wanted to know if i buy a ram with speeds of 1066 is that good enough to overclock or would i need higher speed ram to attain cpu speeds of 3.6ghz or higher. Default speed is 2.66ghz.

Does the Ram speed drop when overclocking the CPU? or does the ram speed need to be dropped in order to attain higher CPU Speeds? or is it something else altogether?

pls help me understand the workings of memory when overclocking the cpu.

Thanks in advance!!

depends on the RAM obviously like you are saying, but when you overclock the RAM speeds tend to get faster, but you could change the RAM speed multiplier too and could make it slower if you want to. I like OCZ and Corsair RAM so i would go for those.

Also apparently those new i5 are really easy to overlock, you should be able to hit 3.5ghz no problem from what i have read on the web.

why would people want to make the ram speed slower?

so how do u buy good ram for overclocking? do you look at the brand? speed of the ram? latency? what kind of ram limits you to OC'ing?

Because thats how you OC as when you up the Base Clock (Bus speed) it clocks the RAM up too.

So for an i5 to hit 3.6GHz you need at least DDR3 1600MHz with a Base Clock of 180MHz ram set to 1066 which gets clocked up to 1440MHz.

As for Brand stick with:

CORSAIR (XMS Series)

OCZ

Kingston HyperX3

Crucial Ballistix

Really any non Value Select should do.

Voltage:

under 1.65V

Timing:

8-8-8-24 or lower but even 9-9-9-24 will not be that bad.

whoa

didn't even notice you upgraded your rig

nice nice

i was thinking to go for gskill 2x2 GB 1066Mhz - http://www.newegg.com/Product/Product.aspx...N82E16820231166

would that not do? can i not overclock the ram to higher speeds too?

Arent all i5 motherboards ddr3 motherboards? that ram you picked is ddr2 it wont run in a ddr3 motherboard

this is an option; ddr3 gskill

r u sure???? i think ddr 2 would run on it..

What does the board your getting s:pinch:an run. :pinch:

nope.

the memory controller(IMC) is now in processor

i5 has only memory controller for DDR3

so you will never see DDR2 based motherboard for i5

[Mannlich]

nope.

the memory controller(IMC) is now in processor

This is only true of the 1366 i7 chips. For the 1156 platform, the memory controller is no longer on the CPU.

My apologies. I stand corrected.

[the big dill]

yeah - don't make a silly mistake of getting ddr2 when your motherboard cant support it, like i did...
