Hi guys,

I was wanting to be able to quickly switch between my settings for my i5 machine. I currently run it at 4.218GHz and it is very nice, stable, but I would love an option whereby it was stock or slightly underclocked so that I could just run fans at minimal speed (for the purposes of audio recording).

Is there any way of having 2 custom BIOS profiles that could be loaded in the BIOS menu, to save me faffing with FSB, VCore etc etc etc...

Thanks dudes!
Mike
 
depends on mobo n bios but yeah its possible, i got that option on my rampage, theres a few custom profiles n can switch between em, pretty sure gigabytes have it too though its not an obvious menu tab you have to press a key to bring it up, should be in manual, or someone else will come along with which key it is shortly no doubt
 
Thanks for that - I will have a look!

I was a 'tard for not mentioning:

M'BOARD: Gigabyte P55-US3L

F11 and F12 in BIOS opens the load and save profiles. I have stock, 4ghz and 3ghz stored.

Bit of a pain rebooting to access them though.
 
Tealc - thanks man, imma try that now!

Just got a wired 360 controller... got a little distracted by Dirt 2 =)

I will post my results.

If others have contributions, keep em coming!

Ok chaps,

Thanks to Tealc I now have 2 main profiles on my computer!

On a Gigabyte board it is as simple as he says:

F11 to save a profile (it will warn you if you are over-writing something)
F12 to load a profile.

You have 10 save slots :D

I currently am running 2 profiles.

1: 4.218 GHz OC - IE my standard profile. This has been stable for months and months.
2: 2.56 GHz UC - This is quiet. I only have the CPU fan and a very quiet 180mm side fan running.

Performance:

Both pass stress testing on the Intel burn test.

Profile 1: peaks around 68*c with all fans running. I wouldn't dare test without them :D
Profile 2: peaks around 63*c with CPU and side fan. Very quiet. Side fan would probably be optional I reckon.

As far as the i5 performance goes:

60 GFlops ish on 4.218, 34 GFlops ish on 2.56.

Anyone think I can trim my VCore at 2.56GHz? It is set to 1.32V. My 4.218GHz clock has been extensively tested and is as lean as poss - forget what it is exactly!

Cheers!

Ambients:

Warm-ish day, warm-ish room. My guess is around 24*c.

Case temp: 27*c.

Profile 1 (OC): 41*
Profile 2 (UC): 41*

With all fans running in Profile 2 it runs at: 37*c

Hmm. Maybe a little much VCore in the UC profile!
 
You'd be surprised how low you can drop the voltage in the UC profile. I think resetting the board to optimised defaults resets all the Voltages to Auto, plus a few other things. A lower voltage means less power consumption and less heat generated.

This takes my 50 degree idle 4Ghz temps down to 36 degrees at 2.66Ghz (i7 920).

I dare say I could drop the vCore and QPI/VTT even lower manually but seldom use stock settings so don't feel the need. But now I'm tempted :)

You are totally right.

I set my Vc to 1.08V as per manual. Now running at 34*c hottest core. This is more like what I expected. I am going to try to push this lower in the interests of temperature.

There may be a Titan Fenrir on it's way :D

Any thoughts, just post - I thank you for the BIOS tip!! I am going to be OC'ing an i7 870 next week (brother's work station). And I did a Phenom II x3 720 yesterday (other brother) - sadly the Phenom seems to be hit and miss as to how far they will go. 3.6GHz totally stable was where I was happy leaving it for him. I got it booting at 3.9GHz but it failed the stress tests, probably more memory than CPU problems, but he is happy with 3.6, so unlike the dog with a bone temperament that I have with my gear, I let it go :D

I was tempted by the Fenrir but in the end went for the Noctua because of the awesome fans (performance not colour) and have it running at 600rpm at idle (quiet as a quiet mouse)
 
Ah the Noctua is a beaut. I am just trying to save a few £££

Now running 2.4GHz, 1.025v. Stress testing with all fans gives 44*c, 33*c idle.

You were right about the love voltages! Going to keep digging :D
