Nice 2500k you have there, 1.4vcore for a 5ghz clock

Really nice 2500K you got there! 4.9 - 5GHz looks like a sweetspot for that cpu for 24/7 use, very nice.

Thanks, I'll aim at 5GHz for daily use & see how it holds up but to be fair even 4.5GHz is plenty fast.

That is what happened to me the last time I tried a Gig board which was the UD3P. It broke every existing record I set with three different boards with ease and demanded seconds.

its all good but going to need some better ram, video card etc etc to keep up with this lot now!

OK I think I have the right thread this time.

Does anyone know what are the effects of using slower RAM (e.g. normal 1333 Mhz) when overclocking e.g. a i7-2600K on this motherboard?

• Is real-world performance like on games, video encoding, compression and compiling significantly affected if you use slower RAMs?
• Will overclocking be limited if you use slower RAM e.g. unable to hit 5Ghz?

My understanding is that since memory is clocked independently of the processor, CPU overclocking should not depend on memory speeds, but it's also possible that slower RAMs = lower memory bandwidth, which may have an effect on overall performance - although my main concern is in daily usage rather than benchmarking.

Thanks in advance.

Welcome to the forum

Yes you are quite right memory is independent of clock speed you got something like 800, 1066, 1333, 1600, 1866, 2133 to chose from.

Bandwidth is still massive even on the slower memory multipliers & looser latency RAM so I wouldn’t be worried using slower stuff. In the real world I wouldn’t say you will notice any performance hit doing day to day things sure I can probably measure some difference in a bench test & you may have to wait a few seconds longer to burn a DVD or Zip up a file but that’s no big deal.

I love it, haven’t seen any that cant clock yet so maybe they all go good.
