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

[owikh84]

Although loves voltage, the L312B460 has a good IMC.

3000MHz 11-14-14-25-1T @ 1.84v passed 32m on air.



3060 validated. That's the max of my chip's IMC could squeeze out.

What kit are you using? CFR ic?


***Edit: I see it now... Trident X... CFR***

Yes, it's the $600 CFR



2 modules at the bottom

[owikh84]

My 4770K is proven to be a voltage lover.

4.6GHz @ 1.44v prime95 for 3 hours



AIDA Stability for 3 hours



So, it's time for a [WTS]

[WeaponX]

Delidded?

[owikh84]

Delidded?

Nope, and I'm not going to delid any chip which can't do 5.0GHz @ lower than 1.5v

[zupernico]

Bath L307B, very bad (4600/4700), I have two , you know something about the L311B

4770 k Air cooled-PM(tomorrow will update batch number)-Batch L307B243
Kingston HyperX Predator 1866 2x8GB@2600MHz (never checked, i thing Hynix BFR)
Super Pi 1M

seems good, Im looking forward for batch info

I have a L311B424 4670k and it needs 1.325v llc Extreme for 4.5ghz. Pic below cpu has been delidded and liquid pro on core mx4 on block.

Nice bro. So how much is the cooling improvement delidded vs undelidded?
Btw, from where did you get the LinX? Mine is not working for Haswell the process is stopped suddenly for no reason.
Thanks

undelidded vs delidded was 10c drop in temp using Liquid pro on core and mx4 on block. Here is LinX - http://www.mediafire.com/?7w8xpkd233i85f8

...(tomorrow will update batch number).....

Batch updated.

[FlanK3r]

Whats your temps (in load) Kozarov? Im still thinking, we have here L307Bxx in shps and I dont know If Il waiting or not...

[cstkl1]

Well hmm haswell adventure. so far tested my psc kit. it requires 0.02v more on m6e compared on m4e. 2133 C7. This is my fully stable clocks with aircooling maxing out at 95c on aida and 93c on prime. tested both for 2 hours.



same batch as owikh.

4.5ghz 1.24v.

[FlanK3r]

so hot with this voltage? Uffff. What aircooling and ambients?

[cstkl1]

hmm its hard to explain but the heat u will only notice on coretemp. i guess because of the die and the tim issue. on casing side its actually cooler.

[lkozarov]

Whats your temps (in load) Kozarov? Im still thinking, we have here L307Bxx in shps and I dont know If Il waiting or not...

My temps:
4.5GHz@1.22V-Linx+AVX running without errors but hit 100C. Same conditions with Prime95 27.7 temps are under 80C.
4.7GHz@1.32V in Cinebench R11.5 is about 80-85C.
5GHz@1.4V 2C/2T in Pi32M temps are under 65C.
All temps are for hottest core.

[st0ned]

That chip looks like a good candidate to IHS removal !

[lkozarov]

I removed IHS from two 3770K. On both temps dropped with 20-25C(I use them with liquid Pro without IHS). I gain ~100MHz with first and ~250MHz with second on air and Single Stage cooling, but on LN2 were much wicker compared with situation before procedure. One finished with broken die. So I prefer not to remove IHS for now.

Just need a little cold...

^^ December air should help

[RPGWiZaRD]

what is it for people who overclock their ivy bridge? The Haswell motherboard cost more, the cpu cost more, but after overclocking, you could hardly feel the difference, why would i want to spend money on it?
also the so call high end side is also horrible , the x79 has nothing for x77 users.
Looks like nothing for me for years. I am disappointed, i was ready to buy buy buy, now i will keep the money in the bank.

Same here. I thought Sandy looked pretty nice compared to an i7-860 @ 4GHz but my upgradeitis bug had faded away a bit since the craziest hardware addiction years when I got into music/headphones so decided I will wait for Ivy. Then Ivy launches and I was mighty disappointed, now Haswell launches and it's the same story....

I had expected Haswell more to max out at like 4.8~5GHz on air for stable aircooling usage at maybe 1.3-1.35v in average, seems like now it fell a bit short from that, only special chips do that and you should expect more like 4.5-4.6GHz tops on air and anything more is a good bonus so basicly pretty much the same were Ivy maxes out typically on reasonable voltages/temperatures and then we are only talking like what, 5-8% IPC difference on average at the same clock, I was expecting a few extra % lead with OC advantages...

Now I feel like meh, could pick Sandy, Ivy or Haswell, not much difference. Years of waiting for nothing... oh well at least some of the Z87 mobos features Realtek ALC1150 chips with up to 600 ohm headphones support. yay

[rge]

Yeah I wanted a new cpu/mobo to play with and been waiting for Haswell, but I have a decent Ivy, benches 5 easy with 1.5v, and 4.7 prime stable with 1.3v. Just cant get excited to buy Haswell thinking I will likely end up with same or worse performance, and worse ocing. what a pisser... back to gaming forums until next release

[cstkl1]

so far all the vdimm that was required to be stable with my psc kit on p67 and z68 is up by 0.025v set on m6e.
still waiting for rma on my dmm.

the biggest benefit i saw was. lol unrar blu-ray and games now takes half the time from sandy 4.5ghz. 8gb in two minutes.
