Getting 5.0ghz stable.

Forum Overclocking : Intel Getting 5.0ghz stable.

Word :    Username :           
 

Hi i am at 5.0ghz on my 2500k@ 1.46v but i have not yet stressed it to see if it is fully stable, however everything is sharp and crisp and seems to be no errors in windows as of yet.

Has anyone actually got it stable at this voltage?

Ok just tested black ops and it ran perfectly.
Just done prime-95 and got an error on the 2nd core only with no crash or bsod.
What could sort this problem?
Temp was high 77c in prime-95
Black ops is cpu intensive and was hitting 57c.

Ok i got my voltage wrong it was at 1.45volt.
I have bumped it up a tad to 1.46v.

Ok seems like that core hates me so i have backed the cpu all the way down to 4.0ghz @ 1.25 volts where it sits happily stable and cool as a snowman ;)

Running a old GTX480 I see no point in overclocking the cpu at all. You could run 2 or 3 of those in SLI and your cpu at stock speed would keep up just fine.

Core Voltage - Not recommended too exceed 1.38v, doing so could kill the CPU, we therefor recommend a range of 1.325-1.350v if overclocking.



Methinks that is just a bit conservative.

Of course there are others claiming that 1.52 is perfectly safe:

If you read the whole thread, opinions are mixed. But I wouldn't operate my puter 24/7 at that voltage

These were the 1st day settings / temps on Son No. 3's 2600K box....with HT on

Stock 51,53, 53, 51 (1.224) LLC = Auto
4.0 Ghz 52, 54, 55, 52 (1.016-1.024) LLC = Auto
4.2 GHz 54, 56, 57, 55 (1.256 - 1.264) LLC = Auto
4.4 Ghz 56, 60, 60, 67 (1.280 - 1.288) LLC = Auto
4.6 Ghz 62, 66, 68, 65 (1.360 - 1.368) LLC = High
4.8 Ghz 71, 77, 79, 72 (1.408 - 1.416) LLC = Ultra High*

The temps dropped 7-10C turning off HT @ 4.8 Ghz. I never did get the chance to go for 5.0 .... At that point, kid wanted his puter back and I let it go. After a few weeks of "burn in" temps are a bit lower.....I still can't get it away from him long enough to do more testing.

Id rerun P95 and use a system monitor that measures each core voltage rather than the CPU voltage. I think you will find core temps to be quite a bit hotter. Download OCCT 4.0 which will test and monitor w/o ya having to use anything else.

Thanks for the help guys but i really need a new cooler me thinks.
I can hit 5.0ghz no doubt stable but the temps as they are now prevent it from been 100% stable.

Yeah it's also gonna make your electric bill go up, and shorten the life of every component in your case, especially the cpu. But as long as your E-peen get's bigger, why not right?

You were almost there, it took 1.475v for me in Win7 to stabilize 5.0ghz with my 2500K.

If you don't supply enough voltage you will not stabilize that 50x multiplier.

Cooling is very important in reaching 5.0ghz stable, I've additionally reached 5.1ghz 100% stable.

Not altogether accurate:

In the case of Sandy Bridge, Intel's max recommended voltage does correspond with the max VID.

In the case of the Yorkfield CPU's, it doesn't. Max VID is 1.3625 volts. Max recommended voltage is 1.45 volts.

Here's where the "1.45 volts" figure comes from:
http://download.intel.com/design/p [...] 320467.pdf page 17.

Need to be careful quoting technical docs. :)

If you think about it, the lower "suggested" figures are obvious.

Q6600 (65 nm) max recommended voltage - 1.50 volts.
Q9550 (45 nm) max recommended voltage - 1.45 volts.
i5/7-K (32 nm) max recommended voltage - ???

If the pattern held, it should be around 1.40 volts.

I am running my i5 at 4.3GHz and it NEVER goes above 63 degrees celsius. I am using a Hyper 212. It has never crashed at that clock - I ran Intel Burn Test 10 times on high and passed. Keep in mind Prime95 stresses your CPU in ways it will NEVER be stressed in gaming. We also have exactly 0 need to go even higher than 3.30GHz (except in games that use only 2 cores - like Skyrim (which is why I overclocked). There is no real need to go that high - bring it down to 4.5GHz and enjoy a longer life for your CPU.

Oh, and if you are using air cooling than your CPU won't last a year at that clock.

Good luck.
