Hows this overclock

[LiamApex]

I know this inst brilliant and i could go further ime sure !

 

CPU:Intel core i7 4790k

 

Cooling: Seidon 120v (120mm Rad AIO)

 

OVERCLOCK: 4.5GHZ @ 1.184v, All Cores

Temps: 

 

However there is a problem cinebench doesnt seem to take my overclock into account. Any ideas ?

4.5 is only 100mhz over stock so it's not very good.

 

up the voltage to 1.35 and find what the max stable frequency.

i know its 100mhz over the boost however its 500 over the normal clock speed thats why is said ime sure i can go further and i have its just that cinebench doesnt seem to take the overlock into account and the score doesnt change

Running 4.7ghz with 1.275v, that's not a terrible OC, but not amazing. 

 

Your overclock is fine, I'd be happy enough w/ it.

the turbo speed is for all intents and purposes the normal speed.

As long as programs like CPU Z say your overclocked you are. It doesn't matter what cinebench says.

yea thats what i though i guess i will just keep pushing the frequency now cheers !

Considering when all cores are stressed you don't get the boost clock it becomes pretty irrelevant. It is a significant jump in multi-threaded applications.

with good cooling you do.

Nope.

this was really helpfull ThankYou !

and?

 

also that's not even an official intel statement or a credible review website, it's just some dude on a forum.

I guess reading is hard.

Turbo Boost operation:

– Operates under OS control – only entered when OS requests

higher performance state (P0)

– Turbo Boost availability is independent of the number of active

cores

– Max Turbo Boost frequency is dependent on the number of active

cores and varies by processor

– Amount of time the system spends in Turbo Boost will depend on

workload, operating environment, and platform design

Sustaining turbo boost:   Use less than all the cores.

Not a good solution for most application since what you loose in core processing power is likely more that what you gain in turbo boost unless your application is just not capable of utilizing all cores.

If you only run 2 cores on a 5670, the processor should stay at 3.33ghz.

If you only run 5 cores (depending on the Imon calabration. I have seen at least one systems that started dropping out of turbo ~ 90% CPU utilization on 5 the 5th core) the CPU should stay at 3.20Ghz

ya that doesn't say anything about "when all cores are stressed you don't get the boost clock"

I don't think you understand what you are reading.

 

The important part of that post was this:

 

 

Turbo Boost Technology opportunistically allows the processor to run faster than the marked frequency if the part is operating below power, temperature and current limits.

He even bolded the important words.

 

If you are hitting the default power/current or temp limits then disabling a core or reducing performance on a core will bring you the other cores up to the higher clock.  However if you have adequate cooling--which you should have--and you remove the power limit--again what you should do--then all the cores will work 100% percent.

 

Furthermore turbo boost isn't unlimited, it's capped (4.4ghz on a 4790k for instance) and OS is setup to dynamically adjust the frequency. 8-44 for a 4790k in the multiplier section of cpu-z, so the base clock really doesn't matter.

Regardless of temps if all 4 cores are stressed there will be no turbo. I've tested it. My 4460 maxes in the 40s and when on a 4 core load it doesn't get to its 3.4ghz boost.

either your temps are too high or you need to increase the power limit or ur chips defective.

If 45c is the temp threshold i feel there is a problem.

this is true my 4790k will only go upto 4.2 when maxed on turbo not 4.4 but when overlocking it hits 4.4 just fine
