true that, but it requires a large amount of disposable income which not everyone has. I'd rather just re-invest in new tech when needed rather than a pricy loop.

@oc argument. I wont go higher than that either if I do.

22nm - 4.9GHz at 1.4v for a long run?
Sorry, but I'm not buying this.

For me and I think for the most peoples out there, 1.42v was reasonable MAX for Sandy Bridge (32nm)
And trust me, this isn't something taken from the air.

You must be very lucky, or they send you a golden chip for a review.

Look here: http://www.xbitlabs.com/articles/cpu...5-3570k_9.html
There are more reviews out there saying exactly the same.

The truth is that overclocking potential is even WORSE than Sandy Bridge due to very high temperatures.

IMHO, Intel failed a bit, why?
Well, high end CPUs were made for overclocking, I know it's a new technology... but this?

Trust me, I'm not alone with that feeling.

CPUs are boring

true that. info please

nm I read the explanation

anyways I will wait for a new revision first before considering an IB chip.

I'm perfectly satisfied with my 2600K. Now I just need a cooler that actually works....

I do like the UEFI for the DZ77GA-70K though.....now I feel jipped cuz my UEFI screen looks like it was designed for kids.

The one thing I do like about Ivy Bridge is the enhanced AVX instructions. Damn are those nice. I wonder how well emulators will perform on these bad boys.

I haven't kept up with emulators for a long time, but have any of them even started using instructions past SSE3?

PCSX2 uses SSE4.

Puget systems in washington listed the I7-3770k, and i5-3570k for sale.

I just placed an order for one I7-3770k.

Edit, nevermind... they said it was listed by mistake and isnt going to be shipped until monday.

Why need more than your i5 750 has to offer ?

Couldnt find single game that would use it properly.

Would there be sense in upgrading i7-975 to 3770K?

Sash · 04-30-2012, 14:54 | posts: 7,068

My retail CPU is an engineering sample, wtf INTEL????

no one reviewd a 3770 locked cpu (non K) so i dont know what to compare the steppings with!

---TK--- · 04-30-2012, 15:01 | posts: 14,724 | Location: New Jersey, USA

core temp prob need an update

Sash · 04-30-2012, 15:03 | posts: 7,068

what about the revision from CPU-Z? Isn't Revision E1 an ES ?

edit: since im venting here, i might answer your post:

Nehalem (your CPU) is going pretty strong, so in your case, you can still wait, the performance gain is close to nothing, and the OC of ivy bridge is crap, probably you get better clocks on your CPU, so no, wait for haswell or ivy bridge-e.

edit2: wow i underestimated intel's hd 4000 IGP, HON (heroes of newearth) runs smooth on max settings

---TK--- · 04-30-2012, 15:05 | posts: 14,724 | Location: New Jersey, USA

maybe their both need an update

Question for you my friend, why in Gods name did you upgraded to the i7 3770 and even worse to a non K?
I wanted to but the high temp and no significant increase in performance over the 2600/2700k made me stop and think.

My logic was this: grab a 2700k for another 2 years until Haswell gets out or AMD brings something new. And i can OC this 2700k to 4.9ghz on air without having the temperature of the Sun in my case, thus resulting in better performance over the 3770k.

dannyx · 04-30-2012, 19:33 | posts: 3 | Location: Paris, France

Well, to be honest, with HT OFF I get 4.2GHz with 1.25V getting hot up to 95°C, but on 4GHz and 1.85V it works nice to 85°C. Air Noctua 14.

1.85v you say?

dannyx · 04-30-2012, 19:41 | posts: 3 | Location: Paris, France

Oops, a typo - 1.185. Load line calibration (I presume) moves it to 1.19-1.192 automatically under Prime95 load and temperatures on 1.23-1.25 go up to 100°C so I gave up on more than 4GHZ although I'm using Corsair water.

What temps are you getting for that 2700k at 4.9Ghz with the c4?

My temps at 4.9Ghz, prime95 blend, all radiator fans on silent.

and at 5Ghz, prime95 small fft, all fans on full and with lower ambient temps.

Click to show spoiler

Not sure if ivy-bridge can stay below 70c at a similar overclock even with high end water, though it may match the performance level at around 4.8Ghz the temps may still be a little higher so you might need to run the fans at a higher rpm, meaning similar overall performance/temps to sandy bridge but more noise

All I want is decent temperatures at 4.3 GHz. I'll receive mine this Wednesday.

I'm optimistic that I can do that, maybe even 4.4 GHz and keep the temperatures reasonable.

Good Newegg vid confirming what other reviews have found regarding oc'ing and temps:

JJ says don't use P95!

mate you get just about exact same temps as me at 4.9 and im only using air cooler with two 1200rpm noctua fans??

He is running silent tho.
