To be fair my cheap as chips MSI 870-c45 does 280 FSB which would give your chip about 4GHz, which is the absolute limit for those tri cores if you manage to unlock it. If it's a C2 version it's also very tough to get them past 3.6GHz, the multiplier won't make much difference with that chip tbh.

for some reason in the bios, I cant put more than 1.325 volts through it, which isn't enough to get the fourth core fully stable and limits the OC on the tri core to about 3ghz from a 250 bus + lower the multi. And no highr than 2250 on the NB. It's either a limitation of the chip or by the mb, I'm not really sure. Possibly the chip as I could put at least 1.4 through the athlon x2 250 it replaced.

It's the motherboard. Some don't have a fully unlocked VRM so will only set the chip voltage to V+max offset.

I have an ASUS motherboard like this. Even with a fully unlocked BE CPU it wouldn't set the volts higher than .1 over stock.

I'd keep it i reckon. That's a good price. Keep an eye on auction prices and see if it's worth selling. If you're only going to make a couple of quid I wouldn't bother. Use it as an excuse to get a shiny new z97 board for yourself and hang on to it until Broadwell. Or you could just post it to me

Even at stock they are fast little buggers so either way you won't be disappointed!
