2500k Owners- What is your Max O/C before a lot of extra voltage needed?

[jacktesterson]

I decided to tune back my 2500k over the weekend.

I was running 4.7GHz @ 1.41v using a 212 Evo P/P setup.

My max temps usually were in low 70's under OCCT 100% Small packet load.


I am able to run my 2500k at 4.4GHz @ 1.30v, saving a full 10 degrees off load temps.


So my 2500k requires a full .11v extra to be stable running OCCT overnight without crashing, for an extra 300 MHz.

I've decided its not worth it right now.

How high can you go before hitting the wall of needing to add a lot more juice?

Do you think 1.41v is 24/7 safe?

4.4 @ 1.30v seems to be the sweet spot for my chip.

My sweet spot I think with my 2600k is around 4.3 at 1.27

My old one.

Needed 1.28 for 4.6Ghz

That is an awesome chip but my results with enabling everything from vt to ht and power saving stuff etc with llc as very high

 

[Puppies04]

4.3 @1.3v, voltage required goes through the roof after that but is managable up to around 4.6-4.7 after that im thermally capped (in IBT)

 

[aaksheytalwar]

But with my current settings my load temps stay in 50s across all cores and not prime load but occt load

I know. :biggrin: Miss that chip

4.6ghz @ 1.20v with a 2500k. I am now starting to think that was probably one of the best chips ever made. I don't have any screenshots. It was a suicide run at low voltage trying to make the chip crash. It didn't which was scary. The new owner of the chip is running into the same situation.

Dude that chip was hitting 4.5 with barely over a volt stable! Just pure insanity!

 

[aaksheytalwar]

How much did you sell it for?

I think like 200 shipped

 

[Rvenger]

$180, I matched MC price.

 

[aaksheytalwar]

Why would anybody match mc price for an awesome chip? they should sell above msrp

 

[BD231]

4.7 @ 1.355v, 4.4 @ 1.265v. Anything over 4.7ghz and I have to use 1.4v or more. FYI $180 is not a deal for these chips, that's retail pricing. I paid 139.99 for mine at micro center and typically you can get the i5's for for $150, these chips are cheap as dirt :thumbsup:

4.5ghz at 1.35v on a 2500k

 

[jacktesterson]

I am going to do some more testing this week.

Takes a lot of time tweaking these things. All I know so far for sure is after 4.4 I need a lot more voltage.

I am working my way down now to see what the minimum is to stay at 4.4. 1.30v is stable so far, so will keep going lower.

Because I don't sell to make a profit from fellow AT'ers.

Playing around with the chip is enough profit for most tweakers

I just sell mine on Craigslist so I don't have to deal with shipping and paypal fees tho.

 

[tuffluck]

lol. this thread has basically turned into "what's your vcore and OC on your 2500k?"

sweet spot for me is definitely 4.2ghz @ 1.25v. i tried going down to 1.2v and it BSOD'd before booting to windows. though at load cpu-z only shows it using 1.20v once in windows.

 

[Don Karnage]

Feel the same exact way.

 

[Hatisherrif]

4.5GHz @ 1.315V - this is the border which, when crossed, makes issues
4.7GHz @ 1.35V - ran it for some time, only to find it wasn't stable and could crash any second
4.8GHz @ 1.37V - crash

 

[MisterMac]

currently running.

4.7GHZ @ 1.36.

Not uber, not bad.
Altho im thermally capped being mid 70's in Linpack\Prime95.
Moreso linkpack obviously.

Installing a raven 03 tomorrow and some more fans.. hopeing to see some C's difference.

 

[jacktesterson]

I guess I should clarify... looking to see at what point do you need to start adding a lot more voltage for small jumps in frequency?

For me 4.4 seems to be the sweet spot.

I am wondering if my chip is just average, etc.

 

[TaranScorp]

My 2500K loves 4.4 at 1.28v and hottest core 58c load.
I do a lot of encoding so I tried a movie at 4.6 and it didn'y even shave off one minute of the encode, a movie at 4.4 was 24 minutes and at 4.6 was 24 minutes. Maybe at 4.8 I'd get a minute less?
4.4 a lot less volts and less heat

Mine would do 4.4Ghz on stock volts of 1.25v. 4.5Ghz needed a bump
