Haswell i5 4670K/i7 4770K batch and o/c results

[Phaseshift]

Should I keep speed step off or on?

[Solid Snake]

The batch number is L307B156, i try 5 of the same batch, and this is the only goodone Vivi.

woow Nachom you have a good chip try it on LN2

Hi guys

these are my bench on Core i7 4770K

4.7 GHz


Testing ADATA XPG V2 @3050 MHz

damn 3050 !!! congrats my friend !!!

[gravimag]

i know that my 4670K can go 5GHz and over...

any idea how much $ would it be for ppl what wants to OC Haswell?
look at the Vcore

[Rob94hawk]

^^Is that on air? Delidded?

[Phaseshift]

Got new batch, L312B152 anyone got info?

[l0ud_sil3nc3]

Got new batch, L312B152 anyone got info?

Yup

only tested 1.35vcore, I am sure it can go lower.



seems like a good batch, do you live in California?

[aussie-revhead]

Jeez you guys are getting some nice chips, my only haswell so far is a 4670K and it needs 1.30v to be stable at 4200 !!!! It bsod's without load at 4500 1.40v .... its sold now so 4770K on the way.

[Rob94hawk]

Just curious guys cause I'm not sure if this is wrong or not but is the voltage reading wrong here? 0.880 Vcore? Until I get a better TIM I'm not going any higher. Prime is running in the background.

[Alex-Ro]

could be,in which casethat is a strong cpu,but what value did you set in uefi,also try 1.64.2 cpu-z....

Yeah I live in the Bay Area, you? Got this chip over at frys in palo alto.

1.64.3 is out already 2 weeks and now we have for for Android:

I do not know because I cheated and tested it out the OC Genie on the board. The board set the values. Until I have a grasp on what I am doing and learn the new BIOS I won't be changing anything. The last system I overclocked was socket 775. So I have a bit catching up to do. IIRC I'm running 1.64.3 cpu-z.

Just got new 4770k from MC today this batch is L310B492. Here is first run of cpu, has not be delidded. Stock TIM + Phoyba HeGrease on water block.

[flopper]

4670k
4.9ghz tried 5ghz but seems that started to become bit complicated.
did run a 32m.
L310b444 batch
its for gaming so no tweaks at all.

[acebmxer]

Ok here is after shot. CPU has been delidded Liquid pro on cores and phobya HeGrease on ihs. So looks like 20-22c drop in temp.



If anyone is looking for linx that will work with haswell in win7 use 10.3.7 found here - http://www.mediafire.com/?3aa7yz5nxfkb97z. 11.0.1 will work with haswell on win8 not win7.

[felix_w]

Nice results !

You kept it with lid for less than 12hrs....

Did you try for max OC margin before delid ?

What a huge temperature improvement bro. Well done on delidding.
My target is 5.0GHz HT but now the current chip needs 1.55v+ with just 2 cores so will skip delidding this chip but will wait for a better 4770K which has lower VID ~ 0.9xxv

Yeah cpu never saw windows at stock speed. First boot to windows was 4.5ghz at 1.2v llc extreme needed 1.21 to be stable. Tried for 4.6ghz but temp was hitting low 90's and not stable and was up to 1.275v.

Thx. I just think my 4670k was just a dude of a cpu. Even after delidding it still ran hot and only had temp drop of 10-15 closer to 10-12c it just sucked.

L314A986

My best chip out of 5 tested , I hope it does not have low cold bug or cbb , will test on cascade at -115c in a few minutes.

i5-4670K Tested on Maximus VI Extreme using Swiftech H220 AIO water cooler.

100% Stable PI 32M 2 runs back to back ( No waza , no tweaks *nothing just boot and run for stability ) at:

4.6Ghz 1.17volts v.core

4.8Ghz 1.25volts v.core

5.0Ghz 1.37volts v.core and can run ,boot into windows at 1.32 volts 5.0Ghz but not 100% stable , cross fingers.

Great chip bud !

I'm thinking of getting haswell and I'm wondering if 4.5Ghz is quite common for it or should I wait a couple of months and see if overclocking headroom will increase?

wait for costa rica batches.

[Rob94hawk]

Jealous of all the 5.0 chips. I tried 50x @ 1.3V and the board was having none of it.

So far my best is 4.6 @ 1.26V.
