So i got a i5 3350p yesterday from a friend, i know its rate is 3.1 to 3.3ghz, but every single cpu monitoring software shows that mine works on 3.5ghz max? how is that possible? i got a ASUS P8Z77-V LX and its got a turbo v evo option in asus software, but i havent turned it on? anyone knows? im just curious, not that it bothers me to get 200mhz bonus xD
i5 3350p working on 3.5ghz?

It has imo to do with having a "Z" motherboard which has the ability to overclock.I think with this chip it has the ability to up the multiplier another two notches.
You can look in the overclock section of the bios and look for the multiplier there,i think it will say max 35 which with a motherboard like this could be applied to all cores.
There was a review of a site where they were overclocking a i5 2400 in which case they could up the "bins" x4 from stock speed (could even have been x4 over the max turbo now i think of it,they managed to reach ~4ghz at the end),means the multiplier,before reaching it max.I think Bittech,but google this you should be able to find it.You probably could play a little with the bclk to make it even faster,but that affects all sorts of speeds so look at that review first and other artikels about it.It's not recommended to do.

ye probalby has to be it, cos its says, synchronizing turbo mode speed 3500ghz and the multipliers are set to 35, dont know if i can change em to see if i can push more, or just leave it the way it is, cos im happy with the 200mhz bonus i got with it

Going higher is a matter of trying,see if there are higher values available,but i think with four times over stock you probably have come at it's limits.Only thing you can do is up the bclk,but as said not recommended because it affects more than just the cpu speed.
Understand that this is overclocking so extra voltage might be needed and the stock cooler might not do so well.

Maybe that the Witcher 3 already reached it's limits because of your gpu,you could try a lower res. to test on. At the end is 200mhz not that much so don't expect too much from it.
Even when the asus software says it's at x37,can it maybe in the bios stick to 35,you could check that as well.Putting the multiplier higher is imo best done there anyway.

ye everything is clear now, just one thing in the end, can setting the multiplier to 37 somehow harm my cpu, cos its like working in the turbo of the turbo mode? i mean if i dont get much out of it shouldn i just keep it the way it is? or is it safe to put it on 37multi

I don't think that x37 will harm your cpu,but from what i read do you get nothing out of it so keep it at x35.
The only thing that might happen is that system stability is not good,in that case should you put the Vcore abit higher until it's stabel again.

Keep an eye on the temperatures,when running all cores at max turbo or above as it is,will it run hotter.An after market cooler would do good for this.Lower temps mean that it can maintain those turbo speeds better.
Doesn't have to be an expensive one btw,just a cooler master hyper 3 evo or similar would do fine.Deepcool has a nice collection too in that price range.You don't have to buy one right away,just keep an eye on the temps first.
And you're welcome.

one more question regarding 3350p and turbo, iv found out that the cpu works on 3.3ghz only when 1,2 cores are active and 3.2ghz with 3 cores, there is not turbo involved at 4 cores so it works on 3.1ghz when 4 cores is used, my question is does the turbo bin steps change if u clock the turbo frequency? cos it works now at 3.5ghz does that mean that it even on this clock works at 3.1ghz when 4 cores are used?

On a "H" motherboard for instance could that work that way,but since having a "Z" motherboard can you lock all cores together and make all four of them run at max turbo. It's a kind of overclocking.
You can check via something like hwinfo32/64->sensors.Put some load on it and see how they behave.It does depend on how cool they run too,when getting too hot can the turbo be disabled.

1) so if i understood right if i increase the turbo frequency to 3.7ghz it should increase my 4 core turbo to, but how can i know at what clock speed the 4 core turbo would work then if the bin step for 4core is 0 at 3.3ghz? or again if i understood right i can "group tune" (i have a group tuning option in asus turbo evo software) all of the cores to work at a specific clock and force them that way to work at a desired clock?

Like i said is it possible to make all cores run at the same speed.If you can make one core run at 3.7 should it be possible to make all cores to run at that speed,it might be necessary to add some Vcore to make it run stable,so test.While testing,with prime95 for instance,could you do the next,
this will keep an eye on all sensor read outs,it also wil say at what max speed all cores will run.
done it, it shows that all the cores are working on 3.5ghz, so they are clocked all the time, they only drop sometimes to 1.6ghz but it has something to do with intel speedstep and c-state power menagment as i have read, so everything is clear now, again, thx for the help

As thought and said by me and RobCrezz is the max x35 for this cpu=x4 over stock.Still a nice boost when over four cores.The drops are indeed the power saving options,but that's fine,just keep them enabled
Again,you're welcome.
