pnetium g3258 has a problem

[n0bleteamleader]

So this is mighty strange and i am at a loss here. i have a pentium g3258 on a msi h-81m e-34. i overclocked it to a whopping 5.25 ghz (save the hate its real so get over it) and i could only put in a voltage of 1.199 v because the mobo limited that and there is nothing i could do about it. now i have run out of space on that little mATX and i bought an upgrade and installed it today. it is a gigabyte z-97x gaming 5 and i have 2x 4gb ram sticks. this processor was made to be overclocked on a z-97 but i can only get a stable 4.1ghz at 1.365 v like linus said but he got 4.8ghz. and yes i do know that each processor has its cap but i went from 5.25 ghz at 1.199 v and on a better board cant even touch that at 4.1 at 1.365v... what in the universe and all that is holy is going on here? grrr i feel got by intel

G3258 probably reacts different in certain motherboards.

I would also say motherboard related. Sometimes, you can have the same CPU on the same motherboard, however if you remove the heatsink and reapply... you may only get 90% of the efficiency you used to have... yet nothing has changed. 

 

Unfortunately this seems like a hardware related issue, and by reading what you gave us information wise, I'd suspect the different motherboard could be the factor.

Did you by any change use windows task manager to see that frequency?

Sounds like you got an insanely good Pentium, and your new chip is just a poor overclocker.  Luck (or lack thereof) of the draw I'm afraid.  Believe me, I'm no stranger to that.  There's a reason my 4770K is running at stock speed

 

Wait, never mind, I misread that.  Thought you had a new chip that wasn't performing as well...

what load benchmark was used on the h81m rig? or just a boot grab?

going through the HWBOT looking at voltages, thats one golden chip

with near non-existent VRM array and 4-pin CPU power.

 

since the VREG is CPU bound, changing mobo shouldn't affect the clock

settings. and performance difs between mobos is negligible.

Yeah like i said im at a loss i use aida 64 to test stability and i did use the task manager then and now but there is a big difference even though this new board is like quadruple the price of the h81 m

What kind of benchmarks did you run with the old MoBo?  If you have any numbers re-run those same benches on the new system.

 

The reason I suggest this is that I'm skeptical of what was actually happening on the old board, as opposed to what was being reported.

There is no way that chip was hitting 5.25 at 1.19v. Sorry, just not happening.

 

If you were using Win 8/10 to view the clock speed it can be off by +/- 1GHz every time you look at the damn thing. CPU-Z is really the only tool you should be viewing your clock speed with.

 

Anecdotal results don't matter with overclocking, you could take 100 of the exact same chips produced from the same factory at the same time and every one of them could hit a different maximum OC. It's called the chip lottery because there is no certainty in what OC your particular chip can reach.

 

What VCCIN (also called VRIN and CPU Input voltage in certain BIOS's) are you set at? Try bumping it to 1.85v if it's still at stock.
