Overclocking problems Intel i7 4770k

[Williamh30]

Good day,

Three months ago I bought my new pc, with an Intel core i7 4770k, MSI GD65 GAMIN, 16 Gb of RAM at 1600 Mhz, Gforce GTX 760 2Gb GDDR5, 750W real power supply, Zalman 9900 heatsink among others.

My pc was working very well until yesterday, I went to turn it on and it didn't start, it gave me a screen where it says that the overclock has failed that I reset the default values, I enter the setup, I don't do anything, I reset and the pc starts but it works for a while and restarts by itself.

Today the same thing happened, when it finally turned on I check the ZPU-Z and I realize that the frequency varies, originally it is overclocked to 4.2 Ghz, now it doesn't stay stable and varies between 3.7 and 3.9Ghz, the voltage also varies: 1.137V, 1.172V, 1.211V.

If anyone can help me I would appreciate it, I am not very expert in these matters.

Attached is an image of the ZPU-Z.

Greetings and welcome to the forum.
First of all, I want to tell you that if you want to overclock, you will have to become a bit knowledgeable about the topic, there is no other way unless someone comes to touch your machine (not all give the same extra margin as you may have heard), and if you do not have the desire to learn or curiosity, you have the option of not touching anything that is not necessary with that equipment.

The second thing I tell you is that, in the meantime, leave the bios with its original configuration, because an overclock that is not 100% stable will end up spoiling the information that forms your system (we are talking about ruining that Windows installation you have and/or your files).

If despite everything you have the desire or interest in overclocking, read much more, give it time, do not be impatient, and as a personal tip, try to get to know your bios thoroughly and have read many guides before asking for help, since what you describe seems like something you overlooked.

Salu2.

hello and welcome

first, specify the source you have, that of 750W real is yet to be seen, put the brand and model
check that the heatsink is well placed and with decent thermal paste and a small amount, in
these cases more is not better

Well, since we're on the subject, what about temperatures during stability tests?

By the way, with 750W on the label, are there any that are so bad that you wouldn't use that equipment? 70% efficiency would be about 525W.

Best regards.
