Pentium G3258 voltage scaling and overclocks

Hi, i have bought 2 of these cpu's and i was wondering what other peoples have been able to manage.
My first one was on preoder from ocuk
batch number:341 8B990
at stock with auto settings it was running at just over 1v
i managed to get it up to 4ghz with the voltage manual set to 1v
4.2ghz needed 1.05v
4.4ghz needed 1.125v
4.6ghz needed 1.2v
4.8ghz needed 1.3v
4.911ghz needed 1.4v (which is what i am running it at normally)
5ghz isn't relly bench stable on both cores but i can boot 5ghz on both cores ok and i can run super pi 1m@5.075ghz on 1.55v

my second pentium is not as good, i bought it about 10 days after the other one for £44 while it was on sale.
batch number: 341 9B312
at stock it was running on 1.086v, so i knew straight away that this wasn't going to be as good.
i manually set it to 1.2v and got 4.4ghz out of it.
4.5ghz needed 1.235v
it needs 1.3v to get to 4.6ghz which is 0.1v more than my other cpu which is a shame.
i got 4.7ghz bench stable at 1.4v and didn't bother going any higher because it wasn't as good as my other one.

i am currently running the pentiums on a gigabyte z97x soc force with avexir mpower 2400mhz cl10 memory at just over 2400mhz. i am also using a thermalright silver arrow sbe extreme to cool them. its a bit annoying because it blocks the top pcie slot, but i'm just run my gpu in the x8 slot as it doesn't make much difference.

Not sure about the Pentium but I wanted to give you a tip about the PCIe port - I have the same problem in that I have an enormous heatsink which intrudes onto the 16x port. SO - I got myself one of these :D

The black bit goes into your gfx card and the other end into the mobo. You can put the gfx card in an expansion slot on your case that's "between" the slots on your mobo (there will likely be at least one).
