Not sure if I have a really bad example of one of these chips, but i've had nothing but problems.

I've tried overclocking this chip in so many different configs and I cannot achieve anything above stock clock speeds.

I use a Noctua NH-L9i cooler FYI which should be fine for taking this chip to about 4.2, even 4.4ghz but i was very wrong.

Put it to 4.4ghz with a 1.3ghz vcore, which allowed me to boot into windows, ok great. Ran prime95 and after a few minutes I was seeing 90c plus!

Throttled it down to 4.2ghz and the temps were not much better, then 4.0ghz which seemed ok, maxed at about 80c but I personally felt that was too much.

So then I settled for 3.8ghz, temps ok at around the 70-75c range but obviously disappointed considering I have read many reports of people easily achieving 4.2ghz with the stock heatsink!

I ran 3.8ghz fine for a couple hours, and then I got a BSOD, put the voltage down to 1.2v which seemed ok. Tested a game and it would freeze, not reliable at all. Even when it was working at this speed, the frame rate would be choppy on LOW settings (LOTR shadows of mordor). Baring in mind this is paired with a Z97 mobo, R9 270x, 16gb ddr3 ram at 1600mhz, and i'm only running the game at 1080p.

Eventually I just settled for stock speeds as it wasn't worth the stress. I can just about manage that game on low settings, I even tried that new south park game and even that was lagging! Also the temps at stock speed when idle were in their mid 40s....

Have I just got a bad CPU? Or could the motherboard be a factor? Might just fork out for an i5 4660, this overclocking business is driving me mad!

Any input appreciated.

Could be a very bad chip or cooler assembling fault? Also, since the chip does not worth as much as other overclockable Haswell chips, you could try to delid it to get a better temp?
It only has 2 cores so cant expect much of a performance from it. It shines while benching and stuffs when people run only the benchmark program and basic windows background. But putting it to the real world, when people run multiple programs (for me: spotify, Skype, Kaspersky, nVidia drivers & GeForce Experience, and a bunch of web tabs) it does not do very well.
 
gjc10212 4.7Ghz @ 1.34v with a prolimatech megahalems black edition and Asus Z97 AR. I no longer have it. I sold it a while back, it was just some experiment.
 
On a 2nd machine my G3258 runs at 58c load @1.25v. That's with an akasa nero V3 which has 2/4 of the heatpipes in zero contact with the core.

In other words, your cooler needs to be reseated, and the thermal paste replaced. use a small blob of it.
 
At the risk of sounding like an echo I'd also say it sounds like a cooling issue, have you tried running it with the stock cooler out of interest?

When I had mine it ran at 4.6 with 1.28v with load temps in the high 60s on a Corsair H75.
 
It's not a particularly good cooler and certainly not for overclocking. It's aimed at stock speeds in a HTPC where the quiet fan comes into play. Haswell based cpu's are just hot running and you need a decent cooler to compensate. Running P95 doesn't help as it uses AVX instructions which really pump the heat up on Haswell and if using adaptive or offset voltage forces a extra 0.1v through the cpu.

As for the other problems, are you running the latest motherboard bios?
 
Thanks for the replies.

Yes I'm running the latest bios. The reason I chose this cooler was due to having a micro atx case, didn't think a full size air cooler would fit!

I'll attempt to reseat the cooler and replace the thermal paste and let you know how I get on!

What should the idle temps be with this CPU? Around 30?

Overclocking in a micro atx case should throw up red flags to you.
 
idle temps are fine at around 30c

you wont do any better unless you go full atx case and a big dual tower cooler imo

depends whats more important,managable temps/low oc vs high oc/full size cooler/case ect
 
No point suggesting to the man to replace his case. That's not the major problem. It can be a contributing factor, yes, but it's not the reason.

Let us know once you have re-mounted the cooler.
 
Low profile cooler is to blame here I would imagine.

Oddly enough I have a NH-L12 and it is absolute turd, cant see the L9 being any better!

Custom PC did an article on overclocking the Pentium using the stock cooler and they managed 4.4ghz IIRC. It may have even been higher.

I have a very good cooler on mine, total overkill (Arctic 120mm jobby) and it won't overclock for toffee.

There's obviously a good few of these out there that are just crap.
 
My G3258 is in a mini ITX rig in a cupboard, with a low profile scythe cooler. I've got it running at 4.0GHz without the temperature going over 70. I overclocked another one for a friend in a mid tower case with a Freezer pro 7 and got a rock solid 4.6GHz without temperature problems.

There must be something wrong with your cooler or your chip.
