Really does seem like I got a golden chip.

Haven't seen anyone get theirs easily to 5GHz.

Guru3d had one - mightily impressed with what the chip can do at 5GHz

 

[opethdisciple]

Looks like 5GHz ok at 1.3/1.31V, but that one single core is a problem.

All below 100C except hottest which got to 104.

20C variance between hottest and coolest (84C) at these speeds/volts.

Average across cores in IBT very high = 95.5C

Just need to decide if I can live with that, or go back down... but how many people get to actually runs their Ivy's at 5GHZ?

Not many, but will it last very long at those temps?

I'll try to remember to look when I pull everything apart to move to new case - though City Link were supposed to deliver that yesterday, so I now have no idea when am going to get it

I HATE CITY LINK!!!!!!!!

Dont we all !! pay for delivery and still have to drive to thier depot to collect it ,2.5hr round trip .lol

Well, that's one thing I am not sure about.

Temps obviously do have an affect on life-span, but what am I likely looking at here? Shortening life to 1 to 2 years? Or will I still see a good 5 years out of this?

I don't care if it lasts a life time. If it's likely to last closer to the latter 5 years, then I can live with temps.

Still playing with the idea of removing the IHS, but knowing my luck, will slip, kill chip and land up getting a rubbish clocker.

I am also getting a case with improved air flow, as the fractal define R3 is not the best in this scenario, which may drop things a little bit.

I have left it running prime all day, so will see what temps have been link when I get home.

If it's maxing around mid 90's, then I will probably leave it at 5GHz.

 

[eyetrip]

Had a failure on one core in prime when I got home - wasn't really thinking after that and closed hwmonitor before I checked temps - DOH!!!!

Bumped the voltage a fraction anyway, so around 1.32V. Will wait til have move to new case before doing any more testing.

 

[Ollie1132]

Since your volts are so low and once you have your temps down your chip won't die too quickly. What youll have to watch out for is if the silicon degrades youll need to up volts a little bit again but that shouldn't be for quite some time.

mine 3770k needs 1.285 for 4.5

 

[eyetrip]

Think I might have buggered my board.

Was swapping over to new case and lightly bumped a capacitor by mistake, but I felt it move. It feels a bit loose now...

Since doing this, am been blue screening on small fft's in prime at 5GHz, where I would only get errors at worst before. Went up to 1.35V and still no joy.

I loaded up 4.9GHz profile which I know to be IBT and prime stable from previous testing, but even getting errors on that now

Even though the 4.9 was stable thursday night, have nudged voltages up a tad to see what happens.

Not looking good though

 

[Buckster]

your temps aren't higher today are they by any chance eyetrip ? just thinking perhaps your ambients are higher

 

[eyetrip]

Happened first around midnight last night. Was quite cool then.

Seems to be holding strong at 4.9GHz with 1.26/1.27V. Been running prime for a couple hours now.

Maybe theres nothing wrong with the cap, but just seemed bit coincidental that after knocking it, things took a slight dive.

Guess will just leave where it is for now and keep testing. Temps aren't breaking 90C.

 

[buzzlightweight]

im gonna be getting my 3770k on monday but wont be building my pc till my bitfenix case arrives.

Am i right in thinking with IB you cant exceed 1.4v and 100c?

HELP NEEDED

So I got my IVY and ran intel stress test, system is ASROCK Z77 MATX

Im using 32gb Patriot 1866mhz Ram, but when I run the ram at its rated speed the system fails stress test in 40 seconds.

If I run the ram at 1600mhz, its fine and will run the stress test for hours.

Ram voltage is 1.65, ivy is running 4400mhz at 1.3v

Any ideas?

 

[eyetrip]

32GB will be a heavy load on the IMC. You will likely need to up the IMC voltages a bit.

Think it's normally labelled vccio

Ahh thanks, how much should I increase it ? Anyone else running 32gb ?

 

[eyetrip]

Go into BIOS and check current voltage. Manually set it a bit higher - say + 0.01V.

If that fails up it again, be the same increment. Rinse and repeat. But do not go over 1.2V.

 

[Combat squirrel]

My board won't let me change the vccio voltage?! asrock z77 professional-m???

ivy is running 4400mhz at 1.3v

Try runing your cpu at 1.25v and llc at level 2, as 1.3v seems high for 4.4ghz.
Leave your ram on auto for now and check what its running at with cpu-z

 

[Combat squirrel]

Wont boot with less than 1.34 in the bios, temps are ok 70-80 load intel stress test, leavin ram on auto makes it run 933mhz which fails, 800 is ok though.

 

[Energize]

Started properly overclocking my cpu, wish me luck.
