Help me overclock my Pentium !!

Hola guys. So my Pockit Rockit is pretty much done. All I have left to do is the PSU cover.



The cooler is one of those Arctic things. Problem is I have never overclocked a Haswell and I know there are some features I'm not quite up on. The board is a Gigabyte, so any one with a Gigabyte should know their way around it. The only caveat is that the board only has a 4 pin CPU power going to it, so it may struggle I don't know. I doubt they would have unlocked overclocking if it couldn't do it though? answers on a post card :D

I will get some screenshots of the bios in a minute if it works like MSI and Asus.....

Edit. Oh for god's sake. Just went to shut down the rig and it wants to install 129 updates for crying out loud. Back later, though I fear it could be much much later :(
 
OK so I had a poke in the bios. Sadly my mini keyboard doesn't have any F keys so I can't get screenshots. However I did poke it a little and have it at 4ghz.

Firestrike 4ghz

To be continued...

Edit. So I decided to run Prime 95. At 4ghz I am hitting 62c on core 1 and 53c on core 2. So basically I have miles of headroom when it comes to temps. It seems stable too, though tbh I never really count P95 as full game stable. Games always seem to stress things pretty hard, especially in titles like GTAV.

Crap just noticed this is in the wrong section of the forum. Mods, can you please move it to the CPU overclocking bit !

OK, so I did some testing earlier and even though I was Prime stable for over 30 minutes I loaded up Dirt 3 and during the benchmark it stopped, made a buzzing sound and then stuck in a loop. This is why I don't rate Prime 95 at all.

So I did some more poking and it seems I found a mini guide for overclocking on these boards. This is it here.

- leave the CPU PLL to auto
- Set Uncore 300MHz lower as Core clock
- Leave the current limits on auto
- CPU VRIN is stock 1,800 thats ok
-Vcore on auto
- Dont use voltage offsets

Leave the Core multiplier Auto, change the Turbo multiplier instead

And it works. Right now I have the CPU turbo at 4.2ghz with a 3900 uncore and I'm sitting here watching prime. Highest temp I have seen on core 1 so far is 66c.

Now to try Dirt 3 again...

Edit again.. It seems my board will only let you set the voltage to an absolute maximum of 1.2v. Any higher and it just jumps back to auto. Actual voltage is around 1.197 so it can't even hold 1.2v. I'm not surprised in all honesty it was only £70 and has a lot of other features like LEDs all around the underside :)

Hopefully 1.197v is enough to keep the 4.2ghz ioverclock happy. Right now it's looking good but I remember from experience that Dirt 3 absolutely hates overclocked CPUs. I've had this happen to me before on other rigs.

Edit again. Woohoo, I got it Dirt 3 stable ! lmao check this out. All ultra settings 1080p with 4XMSAA



Seems that you don't need a stupid CPU after all !

I have one in an ASRock z97 Anniversary mobo that's cranked right up there. When I get a minute I'll look at the settings.
 
Whoever says you should leave voltage on auto on ANY board is "krazy for korn flakes" and you should ignore them. The standard Haswell overclock guide applies. overclockers.com has an exceptional Intel CPU stickies section in their Intel CPUs forum I suggest you have a read over there.

The most important thing with Haswell is that you don't get stupid with the VCCSA. You can kill the fully integrated voltage regulator so easily if you don't respect it.

BTW- a Titan with a Pentium? Are you cocoa for cuckoo puffs?
