I just got the new i5 and have a couple of questions about it.

Why is the voltage lowered in windows while browsing??? Is it like that with all of the i5?

And why the CPU OC itself to 2.79GHz, I didnt touch anything went into Everest and I can see that it is 4% overclocked.

When I open something like Vegas it goes back to 1.24 and stays there while I am doing something. The Turbo is doing something with multiplier, it sets it to 21 instead of defualt 20 which gives me that OC. Also the Cores are 35C idle so I need a better cooler. New Asus boards come with TurboV EVO which ocerclocks the CPU in Windows and checks the stability, I'll give that a go, but I'll select fixed voltage, 1.25v just to be sure. ;)
 
The TurboV EVO crashed at 3.1GHz at 1.25v

It rebooted and now I am running at 3GHz and 1.256v

Is that allright?

Are these chips made for OC?
 
of course not with a stock cooler...

Im talking about with the best ari cooling, with a stock cooler, i would overclock it as high as you can, w/o increasing any voltage.

Thats what i did with my 8750, i overclockd it 300mhz and its perfectly stable at 2.7ghz.
 
I dont actually know what is stoch voltage xD It jumps all over the place. In turbv EVO it says it runs at 1.25v so I think thats its default V but I've seen it as low as 0.8v.....
 
Well from what i can find out,The stock Voltage for the 750 is 1.2875....dunno if thats right though.

You would have thought intel would have put on their site what the stock voltage is :rolleyes:

And matt,If you plan on getting a new cooler id recommend getting a Tuniq tower 120 Extreme :)
 
Well i had the Arctic Cooling Freezer 7 Pro...the first one,not sure whats diffrent in (rev 2) but i wasnt all that impressed with it back when i had my E6300 overclocked to 2.8Ghz.

Not saying theyre bad,I mean its a budget cooler...and is better than the stock by all means.

I know this is double the price of the ACF7,But look at the reviews :)

Nothing better for air cooling than a TRUE. At 4.3ghz, and 1.5875 Vcore, it holds 63c as a max CORE temp.

BTW 4.3ghz just seemed to take extreme voltage, a 4.0ghz overclock only took 1.40v which is my daily OC and with that voltage/OC my temps never see over 50c with the TRUE.

Your underclock/undervolt is a setting in the Bios. I forget what it's called right now though. It is indeed for energy saving purposes.
 
I've been trying to find that setting but couldn't. What were your temps like at default speed with a stock cooler? And do you know what is 750's default V?

''Intel speedstep tech'' is what it's called on my asrock board, and it was under CPU configuration in the bios.

I don't remember, somewhere between 1.25 and 1.30 though. Doubt that helps LOL. Someone else mention 1.2875, kinda sounds right to me.
 
I've disabled speedtech in Bios already, that was like first thing I done :D

I'll have a better look. What seems strange to me that Turbo option dissapears from Bios sometimes.
 
I've run Dirt2 for about 45mins on high settings with 8x AA and Core temps were maximum 59, 58C which seems ok to me.
 
So I changed the setting in BIOS to D.O.C.P. This changes the multiplier to 17 and FSB accordingly to make RAM run at 1600MHz which is the speed of my RAM. In Everest stability test, couple of things changed. The max CPU V seems to be 1.15V and RAM V seems to be 1.80V. Also the CPU temps under load decreased by about 10C. I changed the FSB back to make it run at 2.67GHz, I am still scared of running it higher, I had a BSOD already. Any owner of this CPU can comment on these settings?
