In AMD Overdrive, there is a slider which lets you adjust the multiplier of your cpu. But there are also separate sliders to adjust the speeds of the individual cores. Has anyone tried this? I'm scared to :ohdear:

wait what, you can't even do that from BIOS on my system.
You cant in BIOS in mine either, it's there in AMD OD though.
Edit:
Wait do you mean the multiplier? Yeah only Black Edition AMD CPUs let you adjust the multiplier.
Thats just fucked up.

Not the multiplier, I mean adjusting the multiplier of individual cores.
Maybe I just don't understand what I'm looking at, I don't use Overdrive.
yeah I've never seen it either. I wonder if it would be possible to have 2 cores running at say...3.6ghz while the other 2 (I have a quad) running at 3.4

[QUOTE=gerbile4;22747192]That's not how a CPU Works!
If a CPU is clocked at 3.2 ghz then each core runs at 800 mhz.[/QUOTE]

Congrats, You have now been classed as an idiot.

[QUOTE=gerbile4;22747902]Oh my fucking god what the fuck.
I said before each core runs at 3.2 ghz, and then I am called retarded.
I say each one runs at 800 to add up to 3.2 ghz and I get called retarded.
For fucks sake, which one is right?[/QUOTE]
Each core runs at 3.2 GHz, much as like how many cars run at a certain speed at the same time.

What. I think you just contradicted yourself.
[QUOTE=gerbile4;22748008]If each core runs at 3.2 ghz then why do people say the "core speed times number of cores" is wrong if technically then it must be right?[/QUOTE]
Ok so there is a 1 lane highway with a car moving at 70 mph, compared to a 4 lane highway with 4 cars moving at 70mph. The 4 lane highway will move cars quicker, but you wouldnt say the cars are moving at 280mph would you?

This mans logic is flawless.

:iiaca:
You can adjust each core's speed, big deal? You can set your primary core to run at 3.5ghz, and the other 3 cores to run at 3.2ghz. This way, single-threaded applications will run much faster.
Also, some cores OC better than others, so it's a good way to absolutely maximize your system.

Yes, this is perfectly fine. Your CPU can do this of it's own accord. If, for example, you are playing a game your CPU may overclock 2 of its cores and underclock the rest. The only reasons I can think of for you wanting to do this are to reduce power consumption or heat

All cores in the cpu are the same, how can one OC better than the other?
Minor production errors can make the difference.

This.
If everything scales perfectly though, wouldn't it be logical that it would be exactly as fast as a single core running at four times the speed?
Not that everything scales that well

No it wouldn't.
A quad core at 3.4Ghz is not 13.6Ghz cpu

You won't find any single-core CPUs with 8MB of L3 cache.
But assuming everything was the same, I'd rather handle data 4x faster than handle data at 1x speed 4 times simultaneously.

I know that, but think of it as the cars. Say every car does 1 run every hour. Every run it carries 1 unit of something. So in one hour, 4 units have been carried. That would be exactly the same as one car, running 4x the speed

Yeah, I mean assuming everything else is exactly the same.

While that might be true, it would generate fuckton of heat.

Theoretically, it should be correct. A quad-core 3.0 GHz CPU should get the same workload done as a single-core 12 GHz CPU in a given time. Assuming that the architecture, cache etc. are the same and only if the workload is single-threaded on the single core CPU and 4 threads on the quad core CPU.
Okay Facepunch, I tried it. It hasn't exploded on me so far. Didn't even need to restart the pc. I'm gonna try running a cpu intensive game and see what happens. (ArmA 2)

That is probably the worst way to test your cpu. Download prime95, run a torture test on four threads for about an hour.
all this thing is an unlocked cpu look into the future my freinds

Unlocked CPU's have been around for a while now.
Nothing futuristic about this at all.
