Retail 3770k overclocking

[Hulk]

What are the chances these chips will do 4.2GHz at stock volts?
And what would the temps be with good air cooling? I'd be happy with a cool 4.2GHz with Ivy.

 

[Cythreill]

Every report I've seen suggests you can get up to 4.5 on stock volts but from then on you will need to suffer relatively large jumps in voltage and heat to get higher clocks.

I'm interested to see if the above is wrong tho.

 

[Piano Man]

What TIM was being used. I'm assuming those voltages are already tweaked, or can you go lower? I was hoping that 4.7 would be easier with a DH-14 using Indigo Xtreme for the TIM.

 

[=Wendy=]

Has anyone tried an air cooler with direct contact heatpipes, such as the Cooler Master Hyper 212 EVO?

I have a hunch that they may do rather well with Ivy Bridge.

 

[HexiumVII]

Awesome, if i can get 4.5GHz from an Ivy, i'll be super happy.

 

[LOL_Wut_Axel]

Will 4.5GHz be your final overclock?

 

[blackened23]

Same here, hoping for 75C or less. I think I can manage that at hopefully 1.1-1.15V.

Lapping voids warranty. Removing heat spreader sounds interesting.

I just found this:

I wonder why Intel would do that. It could partially explain the higher temps.

So who wants to be the first to pop off their IHS ??

I would suggest people not to do it. I did it on my old Opteron 165 and I damaged some small parts of the CPU and it did not overclock as well afterward.

It didn't do anything to lower my temps, either.

It's too risky and it voids the warranty. With Ivy Bridge it might lower temps a few degrees, though.

You'd have to be crazy to do it and/or completely not care about throwing your money down the drain. It is not something straight forward and you can easily screw your chip or motherboard up. The OP got 4.5 @ 75C which isn't bad at all, and thats what i'm shooting for when I get my chip.

I did this with an Opteron 170 and it lowered my load temps in the ballpark of 12C. After de-lidding I was able to prime at 3.15 Ghz so it made a significant difference.

I think it's risky to do delidding right now though so I do kinda agree with you... I think we need to wait for more people to try first and if the procedure is really worth it, a bunch of IB IHS-popping guides will show up on the internet. SickBeast, I am guessing these are what you damaged? I do not believe these are on IB so it should be less of a problem.

I can only speak from experience on AMD's... It's not that hard but you have to be careful not to push the razor too deep or you can damage the little IC's that stick out of the PCB near the core.

Yeah I grazed off the top of some of those little things that pop out the top of the CPU package.

12C is a very nice temperature drop.

If this works out I'm sure a lot of people will do it. I still don't think it's worth it if it voids the warranty, though.

I wonder why Intel would do that.

The working theory is to save money but to also preserve the higher end brands like X79 and IB-E. Would you buy IB-E if regular IB could clock to 5.2Ghz on air?

That doesn't make sense. Intel had to cut prices because Ivy underperformed.

It looks like a design mistake/defect to me. I don't see how that would even save them money.

We're the 1%. OEM's dont care about high heat when overclocked to the max. At stock speeds these processors could be passively cooled.

Also its been rumored that it costs intel like 16 dollars to make an Ivy bridge quad core so they'll still make 5 billion this quarter

 

[ShintaiDK]

There is no IB-E. And to say Ivy is underperforming is the biggest joke ever.

IB-E will be coming end of the year

Still not on Intels roadmaps that gets distributed to partners. Unless its gonna come in H2 2013.

Rumor has it end of 12 and start of 13 but who knows with Intel

I stopped believing in rumours. They tend to be wrong most of the time.

Crazy is quite a bit of an overstatement. Just like any hard mod, you have to be competent; if you are, risks are very relative. Who can decently solder is not crazy for overvolting video cards, just willing to sacrifice the warranty - applying known mods with one or two soldering points is practically risk-free.

IHS removal is actually pretty straight forward, you damage something only if you carelessly hack into the packaging without knowing where components are placed. And in this case I wouldn't even care too much about the warranty, unlike motherboards and video cards, CPUs don't die if operated under reasonable parameters.

I've popped a dozen A64, with great temperature and frequency improvements. And I plan to pop IB as well and run it bracket free, if I ever get one.

Chipping the silicon while installing the heatsink poses a much higher risk, which is why you should only run cabriolet if your WB/HSF can maintain even pressure during installation.

 

[SickBeast]

Won't you have to do some type of mod so that the HSF puts enough pressure on the CPU core? The heatspreader has got to be at least 1mm thick and that's going to impact the HSF mounting.

 

[SetiroN]

Yeah, removal of the socket bracket is necessary. Mount pressure is more than enough to hold the CPU in place.

 

[chubbyfatazn]

Does Intel still use SMDs? I haven't seen one with SMDs in a long while. Easy to damage the old Athlons and Optys because of those, but I've delidded quite a few chips and as long as you're careful with your razor you should be fine. Hell I use a knife to delid and I haven't nicked any SMDs.
