Intel Pentium G3258 Performance and Owners Club NOW with GTX 970 - Page 121

IMO - Unsure of how many boards you have gone -0 with... but, mobo temp sensors rarely read below 0c .. and worse, are hardly ever accurate if they do.

You are totally right.
They are inaccurate indeed, that is why i use the multimeter (external temp probe) for more accurate readings but from the amount of ice around socket area well i can say that core temp is 100% sub zero or 0 at lest for sure.

It is the load temp that is intresting in this scenario (3258), and standing around 10-15°C in full load whith air cooling and 4.5@1.3v is awesome for something that price.
Not even close to a phase change unit that sits around -30 in full but still headroom for some more air mhz.

Consider: 100euro for mobo+cpu, 40euro for a good air cooler and 15euro for a pelt = Extreme fun for 160euro (nearly the price of a good AIO liquid cooler).

4.4ghz stable at 1.170v so far.. might try to lower the voltage by .005

Nice. How much extra voltage do you need for 4.5? I'm seriously considering delidding my chip to see how much more I can squeeze out of it. biggrin.gif

Wow that's really good.

Not sure yet, 4.5ghz will be my next test. I was considering delidding as well, but with these temps and volts I don't think I have to. If I can reach 5ghz I'll start some overnight tests with x264 and also test the clockspeed I want for 24/7.

I'm incredibly impressed with this chip thus far, I feel like I won a silicon lottery biggrin.gif . Way different overclocking experience than my old phenom 955.

Hello all,

Bought one of these for my brother to replace his 8350... and the only reason for that is the mobo wasn't well suited for it (crappy asrock 970 extreme 3, absolute junk) - so for the price of a different board I figured I'd get him on the 1150 platform for the same price. Picked up a decent H97 board and this cpu for the cost of a decent AM3+ board - I will only do mild overclocking here, but would 4ghz be stable at stock volts and cooler from the general average here?

Don't really need more then that, as I want it extremely stable, too. Plays a lot of emulation and we just got the Oculus Rift DK2 in (btw, freaking awesome) so I figured a 4ghz pentium should do well for those games as he's not big into multitasking and doesn't really need that kind of performance. Down the line I'm sure he'll pick up a 4790k or broadwell anyways for more threaded games.

Still have it all boxed/wrapped up for his bday, so I canI can't wait to get my hands on one. Last intel desktop processor I used was my 3.4c Northwood s478 p4 I kept at 3.8ghz thumb.gif

Anyways, I figure this pentium at 4ghz or so, 16gb ddr3 1866 and a overclocked 7970ge should do very well for older titles and emulation.

Finally got it installed with a fresh install of Windows and in the Gigabyte z97N-Wifi: http://valid.x86.fr/kk3aad

Hello and welcome!
That's nice you got it for his birthday, that sounds nice. smile.gif

I'm gonna see if I can do 4GHz at the stock voltage now and tell you how it went for me, bare in mind that I haven't got the greatest chip, I think mine may be average or at the most one of the better clocking average chips.

I remember out of the box I threw 1.2v on it for 4GHz without testing lower volts, so I'll see if I can lower that.
I wish the both of you good luck on getting 4GHz easily!

Congrats! thumb.gif
Glad you got it running. smile.gif

Step 4 - Tweak the CPU core ratio and CPU core voltage
Step 5 - As you reach higher CPU speeds requiring more than 1.3 Vcore, you might need to increase VccIN (aka VRIN)

http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics

is there anything else that may increase stability by a bit? 4.3ghz at 1.2v feels nearly stable for me but it eventually crashes in prime95. I just want to get that 100 mhz if possible.

would turning off the igpu help? I'm currently waiting for my discrete gpu, so I can't test that now.
