Is that CPU voltage safe?  Even if you keep the heat in check, I suspect you are shortening your CPU's lifespan considerably.

 

It's well within Intel recommendations.  Yes, it will shorten the CPU life span but you're talking about going from 10 years of 24x7 operation to 3-5.  Anyone pushing their CPU that hard is unlikely to keep it for more than that length of time anyway.  

 

 

Hm... too much for my liking. I might go crazy and delid Lot of good guides around and the 3770K is not extremely expensive so I'll take my chances.

 

 

Check my guide in my signature.

Ah, that's your guide Max, I have read it earlier. Ok, I'll hang on a bit and wait for the Haswell real life benching to see where I am going

It can't hurt to wait another 3 weeks or so, I'd do the same in your shoes.

You don't have to worry if you stay at/below 1.425 - 1.45vcore, CPU should last pretty much - for years. Now i see@@TechguyMaxC have answered already this question

I'm going for 4.9 as soon i will have some time for this

I killed the pricey QX9650 presumably from overvolting after about 1.3y of use.  I run dual boots, one at stock speeds one at overclocked speeds (XP 32 for stock, Vista 64 for overclock).  So much of the time I was running at 1.25v, but most of the time when o/c vCore was at 1.3875, w/ several hours at 1.4v, and a few brief tests up to 1.45v.   Temps were never a problem (always less than 65C, mostly around 58C.  After replacing the dead CPU w/ it's cheaper cousin, I run at 1.3625 at 3.72Ghz and it's been fine since replacing the chip.

I'm on a old good i7 [email protected] for the last 4 years, I have outstanding fps on FSX.

 

At first it run at 4.2Ghz with pretty good result so last year I bought a Corsair H100 Hydro for cooling it and now it runs fine at hi end speed.

 

between 4.2 & 4.6ghz I saw a great improvement in stability & smooth in fsx.

 

i strongly believe that FSX with addon like REX, AS2012, hi end addon like PMDG, scenery from Aerosoft ORBX & Co Run better & better with no compromize after the 4.5Ghz

This was only for sandy bridge 2600K and 2700K. Every chip has different max safe vcore

4.6Ghz on the 920. Nice one! You got a good chip there.

Short answer - the slightly better overclocker, and you eliminate posibility to get "bad chip"(lower OC capability)

 

I'd like to add, it was "at least 100MHz" in my case. I was able to go for 5GHz on air with 2700k. However, i like to add some more Vcore for better(full)stability, and i run it now at 4.8Ghz with 1.4vcore(it's stable at 1.38)since September 2012 without problems. I'll go soon for 4.9, need some free time for this

I'm also running 2700k at 4.8Ghz with 1.4vcore. It actually sits around 1.38 under FSX load with no issues. I could probably drop it down a hair more for FSX, but becomes unstable with other, more modern games.

I have set an offset(+0.040)which alows Vcore to go for more than 1.4 if needs(1.42 max if i remember well). But with fsx Vcore is normaly arround 1.38 like yours, and rarely goes to 1.4. 

I have it in offset mode and C1E enabled, so it only goes to 4.8Ghz and 1.4Vcore when i run FSX. If i do something else, it's on 1.6GHz and 1.08 Vcore(like my laptop)   No stability problems at all, no BSOD's

 

I don't know if you could drop it down for fsx, i have passed all stress testing with lower Vcore, but i had BSOD's with fsx. I read somewhere on OC forums that FSX stress CPU in a very different way than Testing tools, and that you must use higher Vcore for FSX

 

Interesting is that i know two more people's with overclocked 2700K, and voltages are same at same clock's  

 

My settings, if you want to compare, the link is valid 6 days: http://wikisend.com/download/359910/4.8GHz.rar

I have everything identical to yours except LLC set to high. I also dropped the CPU PLL voltage to 1.70. I haven't noticed any differences changing that except I read that it could improve stability and decrease temps. My temps sit between 45-55 during stress test, but I am also water cooling.  Seems to all be working very well with these settings.

woah, that's insane. How much Vcore?

Thanks mate, so if I don't have the ba*** to delid, 2700K is my best choice.

 

What would the difference be if I had 3770K and 2700K both running @4,8-5,0, would the 3770 be much better at the same clockspeed, or wouldn't it matter, bearing in mind that I would run only FSX on that machine?

The 3770K is roughly 10% better clock for clock than the 2600/2700. I was easily able to reach 4.5 Ghz on air with my example. Top shelf RAM with tight timings will allow you to OC with less Vcore volts and thus less heat. I would never steer anyone from the 2600K or the 2700K as they are both stellar chips. Going from a native 3.4 Ghz to somewhere north of 4.5 will net you more performance gains than any hardware upgrade could. The Hyper 212 EVO is about the best budget air cooler out there. Its recommended to have 2 heatsink fans in a push pull arrangement. All chips have their own  performance ceiling when it comes to overclocking and air cooling involves much more than the CPU heatsink. Proper case airflow, case fan configuration, ambient temps, and cable management are all important. Good luck!

Agree with you entirely.

 

It was easy for me too, to reach 4.5GHz with the 3770k. So the equivalent of 4.95 for a 2700k.

 

In fact my chip will run at 4.6 with no issues. Anything above that though and de-lidding is required, as the temps then shoot up like a rocket.

 

I could de-lidd and nock it up to maybe 4.9-4.8, but I see no point, for what amounts to 2-3 FPS.

 

Performance in FSX is excellent, combined with my GTX580.

 

I'm sure the Hyper 212 Evo is a great cooler. But for me, the Noctua NH-D14 is awesome. I can't praise the Noctua enough, super quiet, super cool.
