***The Official Core i5 Overclocking Thread***


I very much doubt it, I would think the Geil would be quite a bit better when been overclocked, and should run much tighter timings when not.

You can use higher voltage memory on the new P55 platform, because most of them work fine at lower volts anyway, certainly at stock speeds, some of the 'extreme' overclocking stuff does require higher voltage to work properly at any speed though.

Most of the older memory modules list the speeds they can achieve reliably when pushed to the limit, not what they can do with slacker timings and or at a lower clock speed, where you can use lower voltages just fine usually.

I think with the old memory it's a bit hit and miss, some of it will be fine, some wont be, infact I would say that 'most' of it 'should' work just fine with a P55 setup.

Cleared 8 hours on small FFT @ 3.8. Temps getting a bit warm after a while. They stay at 70c but creep up hour by hour. I do have a pretty quiet set up though so for normal gaming and things it doesn't go up that far.

Anyone have any ideas how I can mod a Swiftech apoggee to fit 1156

You'll need a new top plate. If you had a S1366 top plate, you could drill holes insidethe S1366 holes, but S775 is too small, so I think you'll need a whole new top-plate.

Then if I recall correctly, you'll need a new base plate as well. And I have no idea if the spacers that Swiftech use to limit board stress are the right height for S1156, so you may need to forego those as well.

I was once in County Cork and I asked an old man at the side of the road how to get to Wicklow. He looked me straight in the eye and said, "Well, you picked a poor place to start if that's where you want to go". I think that just about sums it up. You'll need to do everything the hard way to convert an Apogee to S1156, and then there is the whole issue of whether or not it will be ideal for a hot-running quad-core. They are very good blocks though so it'll probably work fine.

The rest of your Apex kit is perfect though, so if you're looking for the lowest possible cost route the EK Supreme LT is probably the nearest you'll get to instant gratification under £30.

You could always try and get a Supreme used from MM and buy a Universal top-plate if it doesn't already have one fitted.

Thanks for a great post:)
 
Does anyone have an idea as to why I cant change my multiplier above 20?

Also what are the VTT and PCH voltages for?

They are unlocked downwards but not both ways so that is the max you can run. VTT I'm not 100% on but PCH is the chipset I think (southbridge?).
 
OK - well my 4.2GHz overclock with big VCore wasn't stable (it died after a couple of hours, so I thought lets do SuperPi for a bit and to heck with stability testing:D

I don't think I'll see more than 4GHz stable on this system without a radical change somewhere, so I think thats about it for this system. GD80 next:D

So that's how my motherboard does at overclocking? :p
 
managed to get 3.4 at 1.1v temps getting up to near 80's though after about an hour of prime. Could get 3.5 stable for css so pretty impressed.
