only tried it out what settings it would use,

reseated cooler and i actually think i used to much last time! I used less now and got some better temps, even though they are verry uneven,
and I did some damage to my h50 rad frown.gif ill post some pictures soon.

i did damage the radioator some when putting it together again should i throw it away or is it okay?
i actually used more paste then i thought last time, still not any super change in temps after putting on less,
some pictures below.
running prime for 2 hours now to se if i got any better temps.

the picture with the blob on it is not the ony i use right now at the moment actually, had to redo it when i accidentaly lifted the block up from cpu. I used a bit less then on the picture.

yeah thats a bit much paste.
if all you did was bend some fins a little on the rad, youll be ok. just watch for leaks. im sure you would have seen it already.

ok, but i only achieved 2-1 degrees cooler , i dont get it core1 and 4 is running as ideally arount 50-55 but the others rocket up to 63-66
im on bios 1503 and there is about 3 newer versions could those help my cpu ? maybe the bios is broken or the new bios will kick down my sensors?

i would update my bios. i updated to 2103 and im happy.
be very careful if youre going to flash your bios. you dont want to brick your board. but i must say, i found it quite easy to do.

are you sure your pump is running 100% ? are your fans running 100% ?
at 4.2ghz, i think your temps are a bit too high for an h80 using 2 fans. that set-up should be cooling at least as well as a 212+

now iv ran 2 hours of prime like first time and i got this
1st 60,68,66,57
now : 58,66,66,56 and also im not running a h80 im doing a h50 with 2 different fans but it does improve rather than stock corsair.

what thermal paste are you using? that looks really thick. like its chunking off when you remove the block lol
you can check the pattern it makes by installing the block on the cpu then remove and see how the paste spreads, it should be even across the cpu.
If when you remove the block and the paste is thick and hasnt touched all 4 sides of the cpu then there might be an insufficient amount of pressure.

internal PLL overvoltage is per cpu dependant, meaning not all will need overvolt enabled, even at high overclocks of say 4.8Ghz+
i would try the offset voltage method, its real easy once you read the guide and try it out a few times, using at offset of +005 for example will add .005 volts to the cpu VID(what the cpu calls for at a certain mult)
so say you set mult to 42, cpu VID calls for 1.196 for example, using an offset of +005 will feed the cpu a voltage of 1.201 volts
but then you have vdroop and LLC affecting the voltage as well, so its not an exact thing, just a guideline and actual voltage can be taken in windows with CPU-Z, the cpu VID can be read using the program Core Temp
VID will even change under load.

4.2 is not a heavy overclock so you dont need to go extreme on everything as that will just increase temperatures, which tend to hurt the OC when your working with so/so performance coolers.

so my suggestion would be to set it at 4.2, disable PLL overvolt, boot windows, check Core temp program for the VID at idle, and see if it changes under load.
thats the voltage you can work off of using the offset, (or manual if you want)
since your crashing at auto? i would suggest a + offset of 005 or 010 to start
if your still crashing write back here with you vcio/sa voltage, your ram type and voltage used
post screenies like CPU-Z and in bios screen shots, etc

dont go changing everything at once in the bios when tweaking, thats going to make it harder to narrow down the problem.

im using arctic arctic ceramique its pretty thick yea, this time i used a small amount and i had to remove the block 3 times and what i saw when I lifte the block was a round circle in the middle, And then i did not tighten the screws to the max like i did this time, im running 42 multi and 1.205 in vcore right now.

just updated my bios and the cores are the same pretty often!! some times it says 29-30 but then core 2 and 3 flips up to 42 again like before and then gets down after a while.. fired up prime and all the core temps seems to decreased heavily under load!
they only even out in idle after 10 rounds of high intelburntest the temps was 52,64,63,54 and this is on all stock bios settings. dont get it just changed the vcore to manually and 1.2 and multiplier to 42 and suddenly i get 61,70,78,60 after the same ibt test..

talking to intel is like talking to a brickwall
info: Please wait for a site operator to respond.
info: You are now chatting with 'Karla'
Karla: Hello. Thank you for using the Intel Customer Chat Support service. We are glad to be of service. How may I help you?
: Im woundering whats causing 2 of my cores to run verry hot, and the rest of them running as it should compared to other with equivalent cooler,
: i have reseated cooler and i use a proper amount of tim
Karla: the processor usage will influence on the core temperature. However, the core temperature does not indicate a problem with the processor itself since, the overall processor temperature is the one to be measured. Differences between cores could be even 20°C different between them. What's your processor's temperature?
Karla: And, may I have the processor model number please?
: 2500k d2 stepping, at full load my cooler cores is 56 and the otherones 68c but even 56c at all stock settings with a corsair h50 hydro with push and pull fan configuration is pretty high to me.
Karla: The Tcase value for your processor is 72.6°C. Please confirm this at:
Karla: http://ark.intel.com/products/52210/Intel-Core-i5-2500K-Processor-(6M-Cache-up-to-3_70-GHz)
Karla: The TCase value is also known as the thermal specification and,
Karla: this is a number established by Intel® as a point of reference in order to understand what could be expected as per normal processor temperature.
Karla: Anything from the Tcase and below will be the expected temperature of the processor in normal use, anything that doesn't stress out the processor (watching movies, burning CDs, browsing the internet, creating documents, etc.) When the processor is stressed out meaning that you are running heavy processor applications that take control of the CPU or uses it at 100% the temperature will go beyond the Tcase. It can perfectly reach 80 to 85 degrees and the processor will still be OK. The cooling fan is in charge to keep that temperature there.
Karla: If the processor temperature reaches 100 degrees or more it will send a signal to the motherboard to shut down to prevent mayor damages and most likely it won't be possible to turn the computer back in until it cools down.
Karla: The normal processor temperature will depend on the chassis type, the hardware involved and the location of the computer, and it usually is lower than the Tcase.
Karla: Having taken into consideration the processor specifications and behavior, seems the processor is fine.
Karla: Just in case,
Karla: what you could do to make sure the processor is fine is basically making sure you have the latest BIOs version of the motherboard in order to load the latest micro code available for your processor. Other than this,
Karla: youo can run the Intel® Processor Diagnostic Tool to verify your processor's functionality. Please find the download here:
Karla: http://www.intel.com/support/processors/sb/CS-031726.htm
Karla: Since a processor does not partially fail, if the test passes it would be a confirmation on the fact that the processor is fine, running under specifications and not over heating.
Karla: Furthermore, please keep in mind that we do not recommend using third party cooling solutions with our processors. All Intel(R) Processors have their specifically designed cooling systems, therefore the use of third party components instead of the Intel(R) fan, heat sink and thermal interface material would be considered as an attempt of running the processor outside its own specifications, resulting in the termination of the processor's limited warranty.
Karla: More warranty information can be found at:
Karla: http://download.intel.com/support/processors/sb/english_3yr_warranty.pdf
: i know, but it feels so unworh to get the unlocked K version and a decent almost high end cooler and not be able to give it some voltage without making it sweat, I upgaded the bios yesterday and now the cores are flipping out, sometimes it reports the same temp on all cores and then ack to normal as idle temp where 29,43,43,28 and bios reports 32 degrees of idle, may 2 of my sensors be broken or stuck ?
Karla: No, a processor does not partially fail. The temperature to be measured is the overall processor's temperature as previously indicated. Then again, differences between cores could be even 20°C different between them.
: well you cant denie the 2500k is mostly bought for the OC ability it actually has, but i dont dare do it since ive got a "retarded" version, if do wich temperatures should I trust when stresstesting it ?
Karla: Then again, the temperature to be measured is the overall processor's temperature. The processor is made for over clocking, and you are free to use the products as you want, just not being covered by the 3 year limited warranty as it has always been.
Karla: Please let me know Eric, Is there anything else I can assist you with at this time?
: Yea, would a RMA be accepted if me my self thinks the processor is a bad one?
: since 2 of the cores is running sky rocket hot!!!
Karla: The Warranty consists on the replacement on like for like defective units only.
Karla: Nothing described here is indicating a manufacturing defect
Karla: Since the processor is running within the specifications
Karla: it actually runs cooler than the TCase
: yes but its not with the stockcooler!!!
Karla: sorry I did not understand your last comment.
: if i put on that silly little hs and fan you sent me it would probably burn!
Karla: Your processor is not running with the stock cooler, first reason not to apply for an RMA
Karla: 2nd reason, the processor is not defective
: So running another cooler than yours is breaking the warranty ?
Karla: This is also available on the warranty documentation I have previously provided. I would recommend you reviewing all documentation provided for you to be able to see on your own that 1. the processor is fine 2. the warranty does not apply. Just in case, the documentation provided previously is the following:
Karla: http://ark.intel.com/products/52210/Intel-Core-i5-2500K-Processor-(6M-Cache-up-to-3_70-GHz)
Karla: http://www.intel.com/support/processors/sb/CS-031726.htm
Karla: http://download.intel.com/support/processors/sb/english_3yr_warranty.pdf
: yea yea i get it, but if i run your diagnose tool and it overheats what should then be done ?
Karla: It will not over heat since the processor is not doing so at that point. If the processor over heats, then you will see that your system shuts down. That would mean that the processor is not capable of running under full load. At that point, you would need to troubleshoot the processor with your local support group during business hours:
Karla: http://www.intel.com/p/en_US/support/contact/phone/emea
Karla: Still, this will not change the fact the processor is currently running out of specifications (using a completely different cooling solution) so it is not covered by the 3 year limited warranty as of now.
