i7-3770 5.0+ ghz possible?

[HURRIC4NE]

is it possible to run the new i7 at 5.0+ ghz with corsair h100 for cooling and an ASUS P8Z77-V LX for motherboard? i really dont want to go all water cooling bcause of the mess they produce... and im using a thermeltake chaser mk1 case with plenty of airflow

Not if you plan on using it.

 

[T_Yamamoto]

You're going to have to go with a CUSTOM water cooling loop for that.

 

[videogames101]

Either win the silicon lottery or you'll need a custom loop.

 

[aaksheytalwar]

No. You need high end water for that

 

[greenhawk]

first you need the K version of the chip, but leaving that off might be just a type o.

secondly, most reviews give ivy bridge a top of about 4.5 without going into the heavy cooling setups (though SandyBridge could get to 5 without too much trouble in needing heavy cooling setups.

 

[aaksheytalwar]

Besides, not every Ivy will do 5.0+ Ghz even on water, even every mb may or may not manage that.

 

[Don Karnage]

Need a custom loop for 5ghz

 

[Ferzerp]

Being able to dissipate more heat isn't going to help you as getting heat out of your heatsink or waterblock isn't the issue with these things. (Why do people keep assuming bigger cooling will help?)

The only things that will let you keep temps down is to increase the temp delta at the interface or to improve the transfer off the die in some way. You can only do this with active cooling of some sort. Chilled water, etc.

Maybe people talking about "custom loop" are implying that the water is actively chilled?

 

[Zebo]

Yeah it's possible. But you will see 105C+ like bittech did. I would not run 105C 24/7 even on water like they did. They used same cooler you have. I think 4.5 is more realistic.

This.

You might get lucky and get a CPU that will hit 4.6-4.8 on a low voltage.

 

[Pneumothorax]

Could TECs + high end/flow water cooling help in this situation?

 

[Ferzerp]

Could TECs + high end/flow water cooling help in this situation?

Probably, if you want to deal with the hassle.

will need a golden cpu for 5ghz. I have 3770k on water with 360 rad/280 rad and ambients 25C water temp 28C on load. 4.5ghz to 4.8ghz doable for sure though, though cpu dependent obviously.

4.7 ghz 1.28vcore, 3770k w/HT, prime 20 mins, max temps 80C with prime small ffts, prime blend 10 mins temps 72C, going to run prime overnight now.

5ghz, 1.49,1.5, 1.51 vcore, crashed prime though increasing run lengths of prime small ffts.

5ghz (says 4.7ghz and 4.6ghz from throttling), 1.52vcore has another issue, throttling down to 4.7ghz and 1.5v, note temps.

I've been following all 3770k OC threads closely and haven't seen anyone achieve a stable 5.0 with a "custom" water cooling solution.

 

[Zebo]

Same here. Its fuuny when you look at oc db thread at ooverclock.net sb 5ghz all rhe time. Ib about 4.5

 

[rgallant]

Thats the 2nd week 11 I have seen hit 5Ghz. Is it usual for week to be significant?

something like that

http://www.visitingdc.com/images/hoover-dam-directions.jpg will do the trik

 

[LagunaX]

Nope.
4.6-4.7ghz tops.
Beyond that either the temps or the limited 6 phase design of the LX budget board will limit you.

Why is everyone saying custom water? Hell no. There's plenty of people with custom water that have tested Ivy Bridge and NO ONE has gotten STABLE at 5.0 Ghz. Super Pi 1M and 3dmark is about all I've seen...

Custom water if your chip is in the top 1% of IB chips maybe, or if your radiator is hooked up to an AC unit.... lol.

Basically if you want a realistic shot at a stable 5+ Ghz on IB you need a single stage phase change unit, a pretty extreme TEC setup, or a chilled water setup.

-you could be correct but I don't remember any 5.0 ghz sb 7\24 @ the sb + 5days ,some still do not run more than 4.6 today, so I'm not sure if or when ib has better batches[ that with the + 5% ipc with ib] ,sb will ever = ib.
-there's a good chance most of the "golden chips[if any?] are in the hands of noobs still @ stock under stock cooling.
-come this weekend there should be more postings ,so more samples ,more next week.

 

[aaksheytalwar]

Ivy is better but only marginally. And honestly it is more consistent with overclocks

 

[Ferzerp]

That's what I've been saying. Bigger cooling will do zero for it. Bigger cooling is helpful when you want to dissipate more wattage. The problem isn't the amount of heat at all. It's moving the heat off that tiny die which has the icky thermal paste, then a metal layer, then another layer of paste and then your cooling solution.

If you aren't going to remove the poor IHS design, your only option is to lower the temp of your block below ambient (through whatever mechanism).
