2500K getting to 5ghz

Use offset voltage and llc to solve vdroop. Works like a charm. My chip runs at 1600Mhz @ 1.1vcore most of the time.

should have said actually my bad.LLC is enabled but dont have the offset voltage function on the F1 bios.

I would definitely upgrade then. I get very little vdroop with offset on.

saw on the website what a crikey sandybridge did 5.4GHz at 1.41v @ 76C 54 x 100

Link?

2600k or 2500k?

And was that on air?

On air (using noctua D14) noctua stock fans 140mm and 120mm

I lost the link now as I saw it this morning but I try to find it and I will post here

Cool, just interested to see the volts.

leezaal · 27 May 2011 at 14:19

would love to see the vid too.
Mine will wipe out bios settings if i try to boot at 5.1ghz even lowered bclk and it just wont do it, not complaining though it did do 5ghz at not too high voltage and runs 4.6ghz all day long.

5GHz on air does seem to be possible if you have a decent chip. I'm currently running prime95 4 threads at 99.8 x 50 (close enough!) 74 degs max so far, room temp 19.5. Vcore set to 1.38, cpu-z says 1.376-1.384

you have a Golden chip if those figures are correct i cant get 4.7 stable on those volts

leezaal · 27 May 2011 at 17:48

yep 1.376v is amazing for 5ghz defo a golden chip

Is that Prime Blend?

weird_dave · 30 May 2011 at 01:02

In-place large FFTs. Turned out not to be 100% stable

I've backed off to 4.7 and so far so good.
Maybe not quite a golden chip, but perhaps silver

Not pushed mine to see how far it will go yet as its currently at 4.5ghz rock solid stable at 1.26v core. Spec in sig. Might try for more this weekend.
