Buying used 2500k

I can get a used 2500k for 60% of the brand new price.
It's been a folding CPU and is 100% stable at 1.45v and 4.9ghz 24/7.

However I'll propably only run it at 1.2v, seems like this CPU is pretty much average performer not bad OC and not good OC, right?
 
I'd be a little bit concerned if it were me.

I probably wouldn't even think about buying a used processor.
Keep with your current i5, and maybe upgrade to Haswell next year.
Bit late to be getting a used Sandy now, and you're gunna see next to no difference between the 2310 and 2500k in Windows use and games anyway.

That's true, some games are so badly optimized that to get over 70fps I need more CPU power to push the badly optimized games.

Heaven gives me 100% load on both GPU's and 50% CPU load.

I'm currently on one 1080p 120hz TN display
 
"Upgrade to Haswell"


LOL

Haswell is shaping up to be NO faster than Ivy at the mo,just it seems to be a low power chip(that is what Intel are chasing now).


I also have to ask,what is wrong with a used cpu?that sounds sooooo snobbish tbh.
 
nothing's necessarily wrong with it - just you don't know what it's had done to it.

I don't actually mind buying a used cpus - but I wouldn't upgrade to one that I know had been stressed at 4.9ghz all its life, at clocks that will probably decrease its lifespan. I also wouldn't want to be spending a lot of money on one like that. I'd probably rather just stick with what you've got.
Each to their own and all that - I don't really find it snobby at all tbh.

As for the Haswell thing - you may be right - but they are going for ultra power efficiency nowadays mainly because of lack of competition from AMD. There's nothing forcing them to make more powerful CPUs, and we'd probably have an 8 core mainstream Intel cpu by now if Bulldozer hadn't been such a flop... Infact we technically do - the 3960x has 8 physical cores, but 2 are disabled in order to keep up with clocks. If Bulldozer had been more successful then I think Intel would have put more effort into refining the 2 disabled cores of the 3960x rather than just leaving it there...

buy it.. yeah it might of lost two-three years from a TEN year expectancy..
you'll do two-three years.. buy it.. it is taxi tested tough.. air or water-cooled?
temps @ 4.9?

if its holding under 80° air or water BUY IT!

How old is the chip?

Running it at 1.45v could have caused degradation which could decrease the life span significantly

I don't forget, he has been Folding on it,
so most likely 24/7 at that vcore :lol:

And i always fing it a tad weird that people sell nice F@H CPU´s
especially a 2500K because tha IS a very nice F@H CPU.........

Of course in regards to upgrades , but i never think like that...

Ok, I decided to buy the CPU.
According the seller 2 months folding: 4.9ghz@1.45v with NH-D14, never over 65C usually 60C.

Not sure if that temperature sounds realistic(!) but my guess is he runs push pull and high rpm fans.
 
Those temperatures are BS...
D14 with fans on 12v can't keep my 3770k that cool at 4.5ghz (1.2v). Unless his ambients are like 5 degrees anyway :)

Still...hope you enjoy your purchase :)
 
they are BS temps, but still.. a great buy. a simple 4.5/4.6 overclock (75° on D14
@ 1.300vcore) and your rockin'..
awesome score.

am I missing something here?

Why are those BS temps?

I used a D14 on a build for a friend and that was at 4.8 and it never broke 62
 
Well my 3770k nearly breaks 70 degrees at 4.5ghz - 1.2v - and mine has 3 fans on it. They aren't the Noctuas, but the cooling performance of mine seems to be better than the dual fan noctuas anyway...
An extra 300/400mhz on 0.25v more and the temps go down by 5 degrees?
I know they're different chips and everything - but at 4.5ghz, IB should be cooler than SB anyway.
If a D14 could keep a 2500k at that kind of temps for 4.8/4.9ghz, it would completely void any point in watercooling because the cost of it would never outweigh the benefits over the D14...

The D14 is good yeah - but it ain't that good....
 
Ivy is cooler than Sandy up to about 4.5ghz...
After that it can't contain the heat well enough and so gets a little hotter...

The heat issue with Ivy isn't at all as bad as people seem to make out. It seems the people who still think, 'ooooh Ivy is hotter than the sun' are the people who've never actually used it.

What voltage and CPU stress software was used to achieve 4.8ghz and 62c.
How long was the system run?

The seller did state folding I don't know anything about folding but I guess folding might be less stress on CPU compared to IBT (Intel Burn Test).

If it's 24/7 folding for 2 months, that puts enough stress on it to be sure it's completely stable.....until it degrades and starts turning blue...
It wont generate quite as much heat, but it's still up there

I'm not entirely sure what you mean?

Anyway for me I'll propably just run it 1.3v and 4.2-4.6ghz, depending what it can do :lol:
