Hello all,

I have just updated my system to a i7 2600k from a i5 760 as i got a good deal on a second hand i7 and mobo.

I have started to oc it and got to a stable 4.6ghz with a voltage of 3.5.

But getting it to 4.8ghz and running stable i needed a voltage of 1.44v is this a lot?

I could run it on 4.8ghz at 1.4v but it wasn't stable and kept crashing running prime for a bit.

My max temps at 1.44v
Idle : 33c
Full load: 65C

If you guys have any ideas how i can lower voltage and keep cpu stable or if the voltage is safe for 24/7 use that would be great.

Regards, Malthus
 
I'd just keep it at 4.5GHz and under 1.4v as voltages over this may shorten the life of your chip, the gains are also gonna be next to nothing 300MHz is nothing unless your churning on all threads 24/7 and even then unstable overclocks often produce computational errors.

Sit it on 4.5GHz and enjoy a long happy life on your fast chip =]

What motherboard are you using? Tweaking some other settings depending on board could reduce the voltage.

IMO 1.44v is safe unless you plan on using the chip for the next 10 years, in which case the chips life may be shortened.

Edit: And just to echo what lunawolfy said, for the sake or 2-300mhz personally I'd choose the lower speed and voltage. Unless you are doing some heavy encoding you're not going to see much if any benefit from it.
 
yer was thinking of just going 4.6hz cos my temps where like 47-50c on full load

My mobo is Asus P8P67 PRO

I have seen a lot of people able to get 5ghz on a 1.4v is my chip just a bit rubbish ?
 
The only reason you see people get those voltages is that they more than likely have very expensive boards designed to get every single clock possible. Plus those obsessed with clocks havn't been unknown to buy, try and if not of a golden batch return under DSR for a new chip. Rinse and repeat.

Plus all of us with standard overclocks don't rush to the interwebs to share it with everyone. 4.6GHz on a 2600K is still VERY FAST. Remember that.
 
Absolutely no such thing as a golden batch in sandybridge, its pure 100% pot luck to how good your chip will clock.

As for your P8P67 board, try increasing LLC and reducing voltage, it might yield some lower voltages for what ever clock speed you decide on
 
cool will try playing around with LLC otherwise will just reduce my overclock although temps are fine at 1.44v i would prefer voltage in the range of 1.35-1.4
 
IMO you should easily be able to achieve 4.5 for 1.35v or less as you seem to have a decent enough chip.

I've seen 'poor' clocking 2600K chips need over 1.48v for 4.8ghz and over 1.42v for 4.6ghz, you're well under both of those so its more than do-able :)
 
yer i got a stable 4.6 yesterday of 1.37 i think which i was happy with but wanted to push it more as i had max temps of 49 - 55 on full load :)

What is the max voltage i should go for 24/7 use i read up on some places and they seem to change a lot.
 
There is no 'official' word from intel but its widely agreed 1.4v should be an absolute max, well in the view of not shortening the chips life that is.

Many use in excess of 1.4v without issue so its up to the user really, personally I tend to stay south of 1.42v at any cost.

No point pushing for pushing's sake. Unless you got a very high end graphic set up, the extra clock above 4.5GHz simply won't give you anymore frame rate in games, except for may be mmos that uses two cores or less.
 
They also say:

"Not all CPU's are as fragile as others, we have experimented upto 1.50v Vcore and 1.70v memory and had zero issues with reliability, so it seems some of fine when pushing hard."

but obviously it would be safe to assume a lower vcore generally leads to a longer lifespan
 
The advice from OcUK currently stated on the shop site for Sandy Bridge processors:

***OVERCLOCKING GUIDELINES***

- Do not exceed 1.425v core voltage, doing so could limit lifespan of the CPU
- Aim to keep temperatures below 70c underload if at all possible
- Do not overclock with BCLK, again doing so could limit lifespan of the CPU
- Recommended memory voltage is 1.50v, so make sure to run your memory at 1.50v, higher than 1.60v could limit lifespan of the CPU
- These recommendations come from OcUK and Intel, your warranty is un-affected but we highly recommend you adhere to the above to make sure your CPU lifespan is un-affected
- All Sandybridge CPU's worldwide should be run at the above or lower voltages, no higher!

Yer maybe i should stick with a 4.5 or 4.6 until i get a 7970

There would still be no point going higher, you only need about 3.2-6GHz for a single GPU setup, faster clocks assist in SLI/XFire scenarios where the faster clocks keep sync between your multiple GPUs
