Yeah like that one, did it work on a regular z270 mb? And ik it's not safe and it could be broken but the site that's selling them has a one month warranty and a full refund if it's broken or not working and it's like 30% of the price here In Croatia so I can't pass if I know they will work on a normal mb
As alucasa said above, for me, these ES CPUs work perfectly fine in retail Z270 motherboards, for sure. They do not work in OEM PC motherboards sometimes, since the BIOS on those boards are generally limited to specific CPUs. But for boards that you buy alone, from ASUS, MSI, ASRock, etc, no problems.
Yet, Most of my ES CPUs have lost stability in a short period of time; even my 7700K in use in Z270 for motherboard and memory reviews is now starting to have some weird issues on one core specifically, at voltages that most would consider "safe". I'm not even running high clocks...
I am very gentle on my CPUs. I do not use excessive voltages ever; since I use these CPUs to do reviews they are nothing more than a delicate tool that helps me get my review job done, and should I need a replacement, getting one might be rather difficult, and that would make doing reviews difficult as well. For me, getting ES CPU before launch is easy, but after launch is quite hard, since the companies that supply me with these ES chips tend to get a limited number, and after a while they no longer have a CPU to send to me. If this chip dies, I'll have to buy a retail one, and like you, I cannot afford it.
