2500K 5Ghz
- Thread starter Scarey
- Start date
Sure, the screen is crap, it was late....
Trying to get the rig in place before I pick up my GF from the airport. The rig is a surprise for her
I'll get it stable and put settings here. Think I'll get it running at 4.8Ghz to save hassle. Can certainly give my 5Ghz settings though. Try to get it here for tomorrow.

Hi,
That's very impressive and all @ 1.4v
I can't really see any detail in that screen shot, would be good to see your settings, vCore under load etc. etc.
I'd also be interested to see if it could survive an IBT run with your current settings. IBT really is the mother of all stress-tests in my view. Also, for the lazy like me, it usually gives you a fairly prompt (and blue!) answer if things are not quite stable.
I managed to hit 5ghz on my own 2500k though at a higher vCore than you're using. However during stress testing my cooling really couldn't manage the temps to my liking so I rolled back to 4.8. Eventually I settled on 4.5 (though now 4.6) as a good, stable, cool and quiet compromise.
Very nice gift for your GF by the way mate!
Cheers,
Scoob.

My 5Ghz bios settings. I used the ASUS AI suite II to perform the clock, so I've tried to interpolate the bios settings required.
Internal PLL overvoltage= Disabled
Digi+VRM
Load line calibration= High
VRM Frequency= Auto
VRM Speed spectrum= Disabled
Phase control= Optimized
CPU voltage= manual
CPU Manual voltage= 1.24v
This gave a Vcore of between 1.4v - 1.416v under load using Prime 95. The CPU hit 69C at max using a Noctua NH-D14.
The Dram frequency was set to 1333Mhz at this time, so it had little chanc eto cause any problems.
Hope this helps. I'm going to optimize the CPU at 4.8Ghz and increase Dram frequency, etc.

Good job there, that's a fairly low vCore under load for 5ghz - looks like you have a good chip there. I can hit 5ghz with a little more vCore than that, though I've not tried recently (tempted!) However my Antec Kuhler 620, while great at 4.6, seems to start to loose the fight against the heat when I'm at 5ghz. I think the coolant gets hot and the small rad with push/pull fans just cannot get rid of the heat as well so it steadily build. I was touching 80c on the hottest core which is too much, even for benching. This was in IBT mind which is VERY stressful.
I might try again now I have my super expensive cold-air feed setup in place
Regarding ASUS AI Suite: I did some overclocking usign that too, it's not that bad, certainly better than I expected. I'd try to get an overclock in place and stable using AI suite, then mirror those settings in the BIOS as a new stable base & save it as a profile. Seemed to work well. My more recent 4.6 OC was purely from the BIOS however.
I am surprised you didn't need to bump the VRM frequency to 350 and apply some degree of adjustment to the vCore however - I mean using the "add this number of v's" option. I had to add 0.050 in the BIOS to my base vCore to get things stable. Though now I've upped my LLC I might be able to reduce that slightly.
Cheers,
Scoob.

Thanks for those settings,looks like I have a bad chip
Well I seem to have an occasional crash issue when I switch off prime, and the chip reduces it's frequency and voltage. So maybe I will need to look at the VRM frequency.
