|I have been reading quite a bit about early results on overclocking the 3570K and the 3770K Ivy Bridge CPU's. There appears to be a few things in common so far:|
Clock for Clock the tests appear to be a small improvement over Sandy Bridge.
Most appear to be resorting to higher voltages than expected and this appears to be causing excessive heat within the chip.
This heat build up does not appear to be coming out of the chip itself fast enough so even on Cold water they are having trouble keeping the temperatures under control.
Apparently due to the heat, they are not reaching levels typically that they expected.
Withing a small sampling that I read (confirmed C1 stepping), one 3570K by one person reached 4.6GHz on air at around 1.2Vcore but most 3570k's and 3770K's appear to be requiring 1.4Vcore and higher to get between 4.5GHz and 5.2GHz and even with with water they are getting hotter internally than the owners are comfortable with. One question revealed that in the opinion of the tester, the heat coming out of the radiator was NOT very hot, but was cooler than on tests with other CPU's. This led to a discussion of whether the 'lids' were soldered on or glued onto the chips. However Intel is assembling these, the heat appears to be slow coming out of the chip to the heat sink. These CPU's are all coming out of China and The Netherlands and most were retail boxed.
Is Intel selling weak chips overseas? (does not make sense)
Is Intel going to be revising their chips even now to deal with this (maybe a C2 stepping out later in the summer)? (either better stability at lower voltages or better heat transfer out of the chip)
If these are running hot now, is Intel going to need top and bottom heat sinks with heat pipes coming out of the socket and contacts along the edges on the future 14nm and 10nm chips? Or are they going to conquer running stable at lower voltages at the higher clocks that people want.
Or is the answer in using onchip GPU's only on stock CPU's (for OEM's, businesses, and those who want them) and completely removing them on unlocked CPU's, possibly leaving room for more cores?
Would a diamond coating over the silicon followed by a gold plating, followed by gold soldering a gold plated copper alloy lid help remove the heat?
Thought for discussion....
You have to be a little bit crazy to keep you from going insane.
