Diff 2666/3000Mhz OCd at 4.5GHz?

[Mach234 (or similar).]

Hi,

I'm upgrading my system and looking at some of the OCUK bundles. Just wondering, what's the difference between 2666Mhz and 3000MHz memory, if both are overclocked to 4.5GHz? Would there still be the same comparative difference in speed or would they both run at the overclocked bus speed?

As an aside, the standard water cooling options in the bundles are all out of stock, do these bundles need water cooling (Defcon 2/1), or is a good air cooler enough (could anyone recommend a replacement)?

Thanks,

Think you're getting wires crossed between CPU & RAM speeds. If you clock the CPU to 4.5GHz, the 3000MHz RAM will still be faster than the 2666MHz RAM as they're completely unrelated. There isn't a massively noticeable difference when gaming and I'm sure a lot of people will tell you to save the cash and go 2666MHz, but even for a couple of FPS in certain games I personally think the 3000MHz or 32000MHz is worth the extra cash.

Obviously it's better to use watercooling if you're planning a decent overclock, but a good quality air cooler should also be fine, you'll just see slightly higher CPU temps.

Hey OJ,

Thanks for reply. So in the bundles, they don't OC the RAM as well? Would have thought to get the most out of the CPU OC a little boost on the mem would help a treat..

Also need the pc for some heavy number crunching (video/graphics editing etc)..

There's really no need to Overclock the RAM as you'll just cause stability issues without really gaining a lot, just go into the BIOS and load the XMP profile and it's job done, 3000MHz without any hassle at all

Some Skylake CPUs do have issues with 3000MHz memory and need running lower. So don't spend a lot extra for any memory above 2400/2666MHz.

Cool thanks. Was toying with the idea of stretching to the Defcon1 bundles, but think will stay on Defcon2 and treat myself to something extra..

Will post the shopping list for the new rig and see what people reckon. Thanks..

Any ideas when Intel are thinking of bringing quad-channel to their mainstream processors?
