I just want to say alot of the options arent the board but the Haswell itself requires around 5x the effort / messing with different options haswell has whole new set of things to mess with to overclock and get stable and gets very hot due to the TIM and die to IHS contact pressure issue and also the fact the VRM's are inside the Haswell architecture next to the CPU itself AKA on the chip itself unlike any other CPU so once voltage is touched the whole chip starts reacting like an overloaded nuclear reactor with stopped up intakes that go to the cooling ponds lol.
I have tried to explain this many times but the issue is a major issue and greatly affects stability / reliability and greatly affect life of the CPU unlike previous Intel CPU's people are reporting massive chip failures because of overclocking even with very mild overclocks causing these CPU's to up and die unexpectedly. I see these issues as a major issue so I greatly do not advise overclocking the haswell to many people are having failures from very mild overclocks even when done right it greatly is affecting the lifespan of the haswell CPU's even with good cooling and temps staying very well within limits.
I have had 9 customers come thru my door with fried CPU's that were factory overclocked alienwares and such with mild overclocks we are talking 4.0-4.4ghz on I7 4770k's so PLZ understand the haswell has a overclocking issue that if you attempt even mild overclocks cuts lifespan by upto 75% or more the 9 that came thru my doors for testing all failed within 3-6 months so do the math.
I also want to point out dont rely on software to keep up with haswell temps there is a bad issue with software not being able to do this add to it not even Intel testing software has hardly been able to keep up with the quickness of the fluctuations the haswell is known to pulse temps so fast it makes your head spin basically one sec says 50c next 100c then 75c and so on. I also want to say the haswell is prone to thermally throttles so fast software cant record it either only way to do so is to log it while under load then look at the log later and see if it has thermally throttled and such basically the CPU will overheat and downclock itself to lower heat output and will do so even when manually overclocked so gives false positives on good overclocks / stability of a given overclock.
When the haswell thermal throttles performance decreases and FPS drops and the thermally downclocking thing happens so fast unless you are truly watching it would never know why the performance dropped.
watch this at end he mentions the thermal throttling so watch it and maybe you will understand.Edited by rickcooperjr - 9/15/13 at 3:59pm
