New 2500K Overclocking

[LightningJR]

I just got my 2500K a couple of days ago and it's time to overclock. Here are some results.

56K BEWARE

Nice!

 

[Grnfinger]

I must have a bum chip, I need way more vcore for 4500

 

[technicks]

Nice, but it's kinda normal for these chips. Like the voltage though.

 

[LightningJR]

Nice!

Thanks. I had her running 4Ghz at 1.15V as well. This voltage was simple a random choice, I may be able to get better. But I'll OC higher before I drop voltage.

You have a 2600K don't you? I thought the 2600K required more V to OC anyway?

same i need 1.335

it really is the luck of the draw mate. My 2600k doesn't need as much V for the same clock as my 2500k. No idea why apart from having a dud 2500k.

My 2600K needs 1.35-36 to be stable at 4.6. Not bothered really as it's on water and I really haven't spent any time seeing how low I can get it.

 

[LightningJR]

If my mobo was a little better and I had more options for LLC I bet I could get 4.5Ghz @ 1.225V. The voltage drops to it anyway.

Go for a little higher - your Hyper 212+ can handle a little more heat.
Punch in 1.35v an see if you stop at 4.7 or 4.8ghz.
Don't think your cooler could handle the heat from any higher volts though.

nice oc actually, my own i5-2500k do 4ghz at 1.135V in bios 110% stable ^^

Same, I need 1.3625v for stable 4.5ghz

I did Prime95 at 4.0Ghz with 1.15V stable. The voltage drops to 1.136V - 1.124V. I only did it for 45min because I see no reason to use 4Ghz when I can do 4.5Ghz at these temps and V.

I'm gonna bring her up a little further.. I already did some testing at higher speeds but nothing in depth.. The thing is that without more aggressive LLC at 1.4V in BIOS she drops quite a bit and it's far from 1.4V then.. :shadedshu

The higher the V the higher the Vdroop

 

[LagunaX]

Dunno but if you have the option for cpu voltage offset in your bios then that is the way to go - it will idle at stock vcore and jump up the voltage by your "offset" voltage under load to a maximum set amount.

Did not know that's what that option was for. Good info.

mine did 1hour in Prime95 at 1.125V but still i am not air not water

and if i set my cpu to auto / offset mode the board will give it around 1.300V which i think is too much, when i do 4ghz at 1.135V stable.

 

[DOM]

go for x59

 

[aayman_farzand]

Damn you guys have some great chips. I need 1.36v for 4.5GHz. Voltage auto, OC'd using Turbo Ratios.

 

[NdMk2o1o]

Voltage auto,

There's your problem, why have you left voltage on auto? try normal with an offset of 0.05-0.1v that should give you around 1.05-1.15v idle and around 1.25-1.3v on load

My 2600k won't reach 4,5ghz in the first place, 4,3 max

Really? I think this is the first time I hear of that. How much voltage have you tried to give it when overclocking?

 

[theeldest]

My 2500k is 24h prime stable at 4.6GHz @ 1.325v.

But in BF3 I need 1.335v to be stable at 4.4GHz.

Weird how that works. You would figure Prime 95 would stress it more, which it does.

Yes I also find this strange. Maybe he is doing large/small ftt instead of blend.. idk.. I play BF3 quite a bit and have no problems with my aforementioned overclocks.

43 multi 1.3v Vcore, 1.9v pll
tried 48x multi 1.45v 1,925vpll got in bios, but it freeze'd
any where between that freeze'd also
f8 bios
there is a f9 bios though
edit:
i see there is f10c maybe i give a try, but first i have to re-install my os, it's buggy as hell if i leave my pc ilde for 15 min i get a bsod
