Solved Thermal Design Power & overclocking

November 8, 2013 at 01:48:49
Specs: Windows 8.1
I am overclocking an I7-4770K on a gigabyte Z87 chipset board and everything is fine as far as temps go but the TDP is going up to 90+ watts and I think it is causing the CPU to throttle. Is it safe to turn up the TDP as long as temps remain in line.

I went to Intel and did some searching and found the datasheet and very good explanations about how the Haswell chip manages power heat and voltages. I am enclosing the link for anyone who may be interested. It is in PDF format and can be downloaded at this link: http://www.intel.com/content/dam/ww...

I have been able to find all of the settings and what their values correlate to except the TDP. The link I left in the last post made it very clear not to play with the TDP. I can raise it above the 84watts, but it can lead to a lot of problems with adaptive Thermal monitor and Thermal throttling which is what was happening to me. I can adjust the time the Thermal sensor allows the CPU to run over TDP. That is helping and I have also learned a lot about which voltages to play with and what the correlation is to overclocking. The datasheet is over 100 pages long, but has some really good info. It was written for the motherboard manufacturers. I will let everyone know the eventual outcome, but right now I need to get some faster ram. Only at PC-12800 with the XMP profile running at 16000MGz.
Thanks for the 2 links, I am going to read thru both of them too.

You are welcome and keep us up to date. I saved those links, but have not upgraded myself yet so I will be interested in further info. All related OC info is good, except maybe the most extreme, since I will only go with 100% stable at reasonable temps for a long and useful life.
