OCUK Sandy Bridge, SB-E and Ivy Bridge 5GHZ Club

Greetings folks,

I be honest i am not that fussed on overclocking,
At this point i dont need any thing more than stock speeds,
i only really got the system for the new battlefield 3,
And this was due to the fact when i was bata testing MOH i was advised i might want to get a new system before any more testing and so i did,
Other than that i dont really use it for much these days.

But if i get time over the weekend i will try prime and 5 and go from there.

2500ks are better overclockers because they dont have HT, 2600k's produce a lot more heat

i found the same! my temps are hitting 60deg with an h100 @ load, i have just bought this from ocuk as i have heard and seen on youtube, they are amazing at bringing temps down.

if it works as well as i hope i will try and see what is my max oc

btw we need screenies ;)

There's a screenshot a few pages back in this thread.

I probably can't shift any more heat with the kit I've got so I am happy with that...

Even if you run Prime for hours on end! Its not guaranteed to be 100% stable.Ive seen a few people mension that they ran prime for hours and hours and still get the odd random crash here and there with Sandy Bridge! that includes myself.
Now when I make any changes and check for stability I just run Prime for a couple of hours and if it passes,use the machine as normal.

Exactly, nobody is truly going to be using 100% load for hours on end. People are always going on about Prime95 etc and it's almost pointless. General gaming etc only uses say 60% load or so. Even video rendering if you offload some work onto the GPU like I do :)
 
Help me get to 5Ghz ;)

I've got Load-Line Calibration enabled on my P67A-UD3-B3 and set my CPU VCORE to 1.4 in the BIOS which is Prime stable with a i7 2600K running @4.5Ghz

Both CPU-Z and CoreTemp and HWINFO show my VID as 1.2460v which seems pretty low to me, is the VDROOP on the P67A-UD3-B3 really that bad? For some reason CPU-Z show my Core Voltage @ 1.068V which just seems plain wrong :confused:

I don't seem to be able to get my i7 2600K above 4.5Ghz stable but I would imagine that's if the results above are real it's not getting enough power, do I just need to be brave and ramp up the Volts in the BIOS!!

Cooling with a Corsair H80 so temps are around 65 degrees after 8 hours of Prime.

Thanks

I don't have the proof as I didn't do it, but the i2500k I recently bought(2nd hand from another forum) has been overclocked to 5.2-5.3ghz. could ask the guy if he has any screen shots, he's a extreme overclocker so guess he must have run all the benchmarks on it.

I currently don't have the cooling required(arctic freezer 7 pro rev2, lian li a05 case) to push it to 5ghz+ so will be using 4ghz-4.5ghz once I get it built, thinking of maybe going water-cooling in the future so may give it a try then. btw would the gelid tranquillo(thinking about getting it as it's currently £23) be able to handle the temps for a run of super pi @5ghz?

so I'm close but yet so far away from the 5ghz club.

I think you may get to 4.5 - 4.6GHz with the Gelid, don't think they could handle 5GHz. You'd need something like a Silver Arrow or Noctua :D
 
What's the average vcore for a 2500K @5GHz? Not sure if I have the sack to go far enough! So far I can't post at 4.8GHz at anything below 1.37V but it's nowhere near stable even there. Just looking for a rough guideline so I know what kind of vcore should get me there.
 
Knock knock, may I come in please?

well I ended up ordering the ocuk version of the corsair h60 for £37(got a few fans so will try those before ording new ones if the ons I have don't do a satisfactory job.

will that handle 5ghz or still out of reach? been told that 5.3ghz isn't do-able with that so will leave that for the future with watercooling.
