Asynchronous overclocking is bullshit?

[That Norwegian Guy]

In my BIOS I have the option to set different ratios for different cores. (P8Z77-I Deluxe W/D)

 

So I thought for giggles I'd try it. Set Core 0 and 1 to a ratio of 46 and Core 3 and 4 to 45, because I've always struggled with Core 3 getting a lot hotter than the other three cores (about 5-8 celsius in fact)

 

But CPU-Z and RealTemp are telling me in Windows that Core 0 is at 4500mhz when running Intel Burn test. (When only core 3 and 4 should run at that speed)

 

So I'm guessing the whole thing is a hoax?

It's not asynchronus, it's multi-core speeds. One core/two cores run at 4600, three cores/four cores run at 4500. It's based upon core load. This is from what I know, so I could be wrong.

you are spot on

OP: look at this you already noticed this but yeah SLS is right

Yeah but CPU-Z/ Realtemp are reporting the lowest speed for one of the cores that should be running at the highest speed? Is this a bug or are all four cores running at the lowest speed?

per core overclocking doesnt work properly. always gonna be capped at lowest core speed when running any multithread test.

 

single core test wont boost highest core speed to maximum set frequency either.

 

on 1366 I can get it to work properly xeon x5650. on newer platforms per\core OC does not work for me and I think its a waste of time.

 

clock all cores to one speed

[Faa]

Asynchronous overclocking is when you bump the bus (FSB/BCLK) without reducing the ram speed before hand. Synchronous overclocking is when you lower the ram speed first and then bump the bus speed.

Why are you using CPU-z/realtemp? Use HWinfo instead

[othertomperson]

If you're running a program that uses multiple cores, they'll all run at the highest common speed. If you run an application that only uses one core, it will run on that one core's maximum speed.

 

It's why I don't bother with it. Few intensive programs do only use one core.
