Intel i5 650 overclocked to 2.064 volts

[squelchy451]

So this guy on another forum offered to sell me his i5 650 for $45 shipped.
Why the low price? He overclocked it to 2.064 volts. I don't think he ran stress tests on it, but it boots up and shows up on CPU-Z.

Is it worth buying it or would the CPU just sputter and fizzle within a short amount of time due to the extreme overclocking? I think the max safe voltage is 1.4 right?

Thanks

You need to ask him how long it was run at 2v and whether or not it works at default voltage. If it works at default you might be alright.

I wouldn't touch that with a barge pole!

I remember my old 130nm A64 had a default voltage of 1.54 volts, that was 6 years ago! 2v is insane for a 32nm chip

This.

$20 or less would be the only reason to get this.

So he had screens showing that much voltage going in the chip? Which boards allow that much?

I thought there were safeguards in place to prevent basically frying chips...

But I'd say if the price seems right to you, I'd wonder if he ever actually ran that much through it and you might just get a discount chip that's perfectly fine...


*I admit that I'm talking out my ### a bit on this, but I didn't think you could push that much.

I'm suprised the thing didn't pop.

If you don't already have an LGA 1156 motherboard, You sure as hell shouldn't buy it. Even if you do, it's a huge risk as to whether it will work or not. If you don't have a board, you should just get a cheap H61 mATX board and a Pentium G620.

Ya, the max v for sustained overclocking for i3's is ~1.4v. I wouldn't run an i3 for any sustained period above that.

My 1156 MB has settings for up to 1.900v for my i3 -- although anything higher than 1.6v in the BIOS flashes red -- LOL ...… I had no idea how high the vcores settings went until I just checked.

If it was a short overclock test and the CPU wasn't overheated for any amount of time (the CPU's safety's will kick in anyway, throttling it) it might be ok.

If the CPU is listed as "in good working order" and boots up and runs, then it's probably ok. For $45 shipped you wouldn't be out much if it burns up later if you have an 1156 board to put it in.

When I look at this thread I have a lot of confidence in modern CPU's and their ability to be heated up to the point of throttling or even shutdown, and then re-fired/rebooted up and then run fine.

I remember running my mobile xp 2500+ at 2v for brief time to bench at 2.5ghz with the thermalright 900. The system lived another 2 years before I replaced the system with a AMD x2. Fun times lol

umm, the temps in that thread are below Tjunction max. It will run just fine and not even throttle until 100...

edit: note I didn't say anything about lifespan, but those chips are designed to last at least the length of the warranty as long as they stay under 100C
