Have you tried the "Performance Optimization" using Samsung's SSD Magician software version 3.2?

Actually, I think you'll find that, from an engineering standpoint, that is an absolutely FANTASTIC sign in terms of manufacturing. In theory, if transistors were perfect you could run them at any voltage and you would generate zero heat. Obviously this is not possible. We have heat losses and these are caused by internal resistances and current leakage.

If we were always at a thermal limit it would be because the design was so poor as to allow huge amounts of leakage and unnecessary resistance. Ideally we want to get these leakage values as low as possible. This means generating as little heat as possible. Less leakage also means higher internal voltages which also means higher signal strengths and higher possible clocks.

By any measurement Ivy is an engineering success. This is even more impressive considering that it is Intel's first venture into 3D transistors.

It's just luck of the draw dude. If you have $1300 for cooling maybe you can buy a couple of Ivy chips and find the best clocker. Just because you have excellent cooling doesn't mean your CPU is going to magically be stable above 5.0GHz, it takes more than cooling, the other hardware has to be up for it as well.

auto gives the biggest difference tho, uses way to much most of the time
i like to see vcore go down to less then 1.0V when idle,
instead of a fixed vcore, that will be the same all the time,
idle or not..
just my preference, not saying its better then fixed or anything smile.gif
always use fixed vcore if you start ocing, then choose offset if you like after that..

I prefer offset mode too because I like reduced voltages and clock speeds when idle. You do have to find your ideal voltage with manual and then try to work your offset to that voltage.

Did you use any tape or anything as padding around the core or did you just mount it right on there? I seem to recall you using padding around the core previously but I can't seem to find the post. redface.gif

For those that are using CL Ultra on the die and got 20-30+ of temp drop, what application method did you use? I feel like having just a dab in the center and pressing down isn't the best idea, since the die isn't symmetrical. So....a few dabs? Credit card spreading? A single line?

Also, how much of a difference does bare-die make, vs having the IHS? I have an EK Supremacy waterblock, so I'm guessing it would be relatively easy to go bare-die? Anyone tried it with that block?

spread it all out smile.gif
a thin layer is enough..
small dot like this for example on ihs


should look like this when you spread it all out, but your dont want to see it "floating" like what you
see on the lowerside from this pic, whats to much, you can suck up again using the seringe

same goes for the die, but you can use even less then on the ihs pic,
i did all sides with it, when i finished the die, i put on the ihs again, pressed a bit,
took it off, looked at the print it made on inside ihs,
and did a (very) thin layer on inside ihs also ..i had 25+C tempdrop

i would do bare die only with a water cooler,
i thought about it with my aircooler, but the thing weighs more then 1 kilo..lol
the difference isnt really big, the best/biggest tempdrop is by using liquid pro/ultra on the die, with ihs, or without
bare die gives some more tempdrop tho, Sonda5 is our specialist with that smile.gif

I used 5mm Fujipoly Exreme thermal pad around he die for PCB support and to help cool.







Lonewolf I don't think everyone is going to see 30C cooling improvements. My 3570k ran much hotter than the new 3770k that I just got. When I delidded the 3570k it was much easier to do because there was larger gap of glue between the PCB and IHS. With the 3770k I delidded the IHS was on much tighter and it was much more difficult to delid it. I'm stress testing the new delidded 3770k and right now the temps are better than lidded but not as good results as the 3570k that I did and I think its because the 3770k had a better IHS mount from the factory.

i think a better mounted IHS from factory is going to help keep the CPU cool.

did you test it before delid, did it run cooler? compared to other not delidded chips?

yea, if intel is gonna listen to Valgaur's letter he making, this problem will be solved soon ..lol
i only hope they dont decide to solder it tho .. biggrin.gif

yes, so far it's been for me. just mind that completing Cinebench without crash is only half of the story. you NEED to go to Windows Event Viewer - Custom Views - Administrative Events, and make sure there was no WHEA warnings during that Cinebench run, if they were then you are still unstable and should up the vcore until those warnings are gone. once there I cannot make such overclocks unstable under anything.

what's your CPU batch # ?
