Intel 3770K Overclocked to 4.6Ghz - Gameplay Thermal Testing

[Ollie1132]

Yeah but the thing is the 670 "MAY" be able to have the 680 firmware flashed to it or something... which would mean OC ability on the 680 PCB'ed 670's. also even with out overclocking the 670's are beautiful performance wise

but with ~20% faster performance and at half the watts.

Agree on temps though. Intel need to lick this when the rev B 22nm cores tape out. Half the wattage on a core half the size equals similar heat output. 22nm just seems too small to dissipate all the heat.

It is not half the wattage or anything like it.

See my post here: http://forums.overclockers.co.uk/showpost.php?p=21754267&postcount=79

IB: 1.4 billion transistors on a 160 mm² die at 77W TDP.
SB: 1.16 billion transistors on a 216 mm² die at 95W TDP.

IB: 77/160 mm² = 0.48W/mm²
SB: 95/216 mm² = 0.44W/mm²

IB per unit die area needs to transmit more heat away.

The fact that when you start applying voltage more than linearly increases the power output/temps mean your hitting limits laid out by physics.

Intel can't do anything about it short of reducing the power requirements.

Unfortunately, as dies get smaller, over clocking is going to get harder, just because it is more difficult to take the heat away.

people moan but 4.6 at 78 degrees highest under full load is not bad

 

[Ollie1132]

don't get why anyone would moan anything over 3.5Ghz is beautiful.

power saving on the Ivys is superb too

I'm currently using I mode - so my GTX480 is not getting used for Firefox etc .. which is good

I'm down from around 180-230W idle/general usage on my Q6600 system + 480 and 340W encoding

down to around 100-110W idle/general usage on the overclocked 3770k + 480 and around 150W encoding

big difference

Don't you take a hit with 3D performance and image quality using I Mode?

a little bit - not really tested much yet

but Heaven benched fine - and looked as good as directly into my 480 I thought

Sorry about the bad link in the first post. I have amended that now.

I thought it was interesting the heat delta between demanding games and synthetic benchmarks on the IVY. My 2600k would always be around the same temps when gaming as when running benchmarks but the IVY has a vast 15-20 degree difference.

I'm running at 4.7Ghz on 1.28v now and think I'll probably stop there as the performance is blistering and the temps during normal use are always at the most mid 60's.

Given all the bad press the IVY has had for its OC potential, I was pretty happy with my results. Sure I'm not getting 5Ghz anymore but my nVidia surround performance is a lot more consistent now when less random frame drops when using my 680's in SLi.

Also remember how many times are you going to run CPU at 100% when NOT stress testing?

Video encoding, rendering and other every day usage stuff.

Thankyou OP for doing these tests this is exactly what i said on the Ivy OC thread about temps and gaming.There is nothing wrong with 80c stress testing and 62c gameplay temps imo.

GTAIV is cool @ 60c so why not push for 4.7? If the stress test temps really scare you then open up the case, set the fans to maximum and ignore the noise and just wait for 5 hours to see if it will pass.Having the case open and the fans on full will do less damage is your temps rocket to 90c and it will be only during this stree test you will ever get near 90c.

If it does pass without a crash then go back down to the old cpu fan speeds etc and play your favourite game in silence.I guarantee it will be stable and the temps will be 15c lower than the stress test and u get the small % boost from the extra 100mhz.

I have the same mobo and CPU as you and I was curious to what Voltage settings you used to get 4.6ghz. At present I have my system set up to overclock to 4.4ghz with voltage set to - offset @ 0.020. when I set the CPU any higher i am getting a blue screen. I think its because the voltage raises too high. Do I have to set the Vcore to a set voltage? If so what?

Any information appreciated.

OP - for interest have you checked your windows logs for any WHEA errrors ?

I found I needed 1.3V + and gave up - went back to 4.5 gig

even 4.5 gig requires 1.285V + LLC Extreme ouch

It's not till you up and swap to Intel you find out first hand how bad AMD are.

^^ This, a while back I went from a 1055T to a 2600K, my fps went up by nearly 100fps in some games, shows how much AMD cpu's hold things back... Weren't the older 1055T range better performers than Bulldozer? How did they mess up that badly?
