Just got some more life out of my 2500k

So I was not as big into pc gaming as I was a few years back but I recently have been getting back into it. I bought a computer about a year ago at a garage sale for 50 bucks and it had a partially dead motherboard (some USBs didn't work and the vga port was ripped off???). So I buy a cheap motherboard from Amazon for like 50 bucks. I clean off the thermal paste and there it was i5-2500k I was like oh wow. I didn't have the money to get a Z77 motherboard just enough to to get a gpu so I went with a GTX 960 SSC so I had an upgrade path (SLI etc...). Well just last week I found on craigslist a Z77 Extreme 4 Motherboard by asrock and and decided to pick up an NZXT case and a hyper 212 Evo. I'm now successfully over clocked to 4.8ghz and staying under 70 degrees on a synthetic load. Just thought I would share my adventure with this beast and I'm so glad I went to that garage sale. Hahaha

Fantastic overclock. It is very cool to see people achieving such high overclocks with older cpu's and being able to squeeze out more performance out of it.

Some CPUs will need more voltage than others to get the same overclock, that's just a part of the silicon lottery.

You can try to lower the voltage bit by bit until the PC crashes during prolonged benchmarking.  then just increase it again until it is stable.

I'm just going to leave it. It's pulling that at a synthetic load so I don't think it's an issue. I just did some googling and I should be fine. Thanks for the input though.

High, but not necessary dangerous. As long as your system is stable and temperatures in control, you're good to go.

Intel states that the CPU's thermal limit is 72.6°C and you're below that.  I've seen quite a few Sandy CPUs run in the high 80s or even in the 90s for extended periods of time and survive just fine. 

 

You have nothing to worry about really.

That's a bit high. Try lower it and stress test to prove its stability. Even if you have good cooling, it's better to stay below 1.35V while the red line is 1.4V.

It should be fine as long as you have it cool enough. I have a 2700K at 1.45v as well (4.9 GHz). My 2500K (1.4v for 4.6 GHz) is just chilling on my desk now.
