Using turbo on Intel Core i7-3770K?

[johndud]

I just built a new rig recently as shown below and i dont think its performing right, ive been playing Company of heroes Blitzkrieg mod with all high settings on 8 player extra large maps and im getting 15 fps at times, this doesnt seem right for my rig now, so im wondering if its just the game that intensive or if something else is wrong.

Also i want to be able to turn on my turbo on my processor so how do i do this? i heard you can turbo it to 4.1 without making any voltage changes and using just the stock heatsink....

I'd suggest turning off turbo mode and setting CPU multiplier to 40. That stock heatsink should handle (at least it did for my 2500k).

Why would you suggest that? and when using intel extreme tuning utility it says i have 4 active cores, running in this order, 39x, 39x, 38x, 37x,

Because turbo boost doesn't work on all 4 cores at the same time. However, if you make your CPU clock 40x, then it wouldn't matter and you wouldn't need turbo boost.

intel ivy bridge generates more heat then the sandy bridge CPU's

well you can try but monitor your CPU temp intel ivy bridge generates a bit more heat than the sandy bridge cpu's i have a i7 2600 and it uses turbo boost up to 4.3 ghz and runs fine with stock cooling

 

[Sunius]

I know that, but it shouldn't be 20°C difference. I've had load temps on ~68°C with those settings with stock heatsink with prime95. I think it's acceptable to get to 80ºC with prime95 with ivy bridge CPU . There's no way you could stress it that much in everyday use.

So just set all 4 mulitpliers to x40 and watch temps? what should i do if it does get past 80 degrees? what voltage should i put it at? im using intel extreme tuning utility

I'd suggest use BIOS for that. Don't change voltage, leave it at default. Just set CPU multiplier in bios at 40x.

ok idk how to do that, ill have to look it up

To enter bios just restart your PC and keep pressing DELETE button until it enters it.

How much of an fps boost should this give me?

And since your answering my other question on another thread, if i get another 670 for sli, and do this x40 multiplier will i eventually have to mess with voltages?

 

[Sunius]

If eventually you mean if you want to increase the clock speed to more than 4 GHZ - then yes. However, if you won't change the CPU speed, you won't need to change the voltage.

awesome, how much of a boost did this give to your games?

 

[Sunius]

I don't really know. I didn't install any games before I overclocked my CPU

Ok what i did was, went into bios and disable intel speedstep tech- its a power saving tech, and then set turbo to 4.00( there are options for 4.2, 4.4, 4.6 etc) is that what im supposed to do? it i didnt see an option for disabling turbo and just setting x40 mulitplier, but i guess i could try it with the intel extreme tuning utility. Right now IETU is showing 3.4 ghz and only 1 active cores, idk if thats what its supposed to do

Edit: just looked at the rest of the info on IETU and its showing core multipliers at x40 now instead of 39x, 39x, 38x, 37x. I also saw that i can disable turbo boost short power with IETU, i wonder if i should

You shouldn't disable intel speed step... You've got asrock board right? It should look like this:

Put CPU Ratio to Manual and "Max ratio" to 40. Disable spread spectrum as well.

Ok ill do that now

My CPU ratio setting said all cores or per core, so i set all cores and then 40, i forgot to disable the turbo tho, im gonna do that now

If i disable turbo in bios, and then set all cores and 40x, turbo reenables itself, there is no option to set all cores and disable turbo, i mgiht be able to do it in IETU tho

Are you exiting bios by pressing F10 and not escape? It should not turn itself on.

I just save changes and exit, its the same thing, but im playing BF3 right now and cpu is at 70 degrees, 4.1 ghz, and 3 or 4 active cores

THe turbo enables itself even before i exit bios, i cant even click on disable turbo if i have all cores and 40x set

Oh well I guess that's normal behaviour. I would not worry about it. Grats on your overclocking!
