Help me get my 2500k to 5ghz

post #1 of 11
Thread Starter 
Hey guys,

This is probably just another one of those threads about some noob that doesn't know how to overclock his CPU, but here we are.

So, my specs are as per my sig rig.

Multiplier: 50x
CPU voltage: 1.45v
LLC: level 6 (scale of 1 to 10)
Turbo: off
Real-time ratio change in OS: off
C1E: off
EIST: off
C3, C6 states: off
BIOS: F7 (latest)
Everything else: auto (stock)

Right now, a prime95 worker will fail during stress testing.

Any ideas on how to increase stability without further increasing vcore?

Thanks

One other way is to increasing the LLC level further, that would control more of the vdroop but will also increase the vcore should the CPU need it to stay stable.

I could try that, but I would like to keep it at 1.45v or lower. Would PLL overvolt be worth a try?

Do you have Internal PLL Overvoltage enabled? If so, the only thing left would be to increase the load voltage, either by increasing the LLC or by increasing the volts. It isn't unusual to require higher volts than 1.45V at 5.0.

you cant want your chip can get 5.0ghz at 1.45v. either it can or can not you dont get to choose. either raise your volts or downgrade your clocks. that is the only thing you can choose

please dont give false information. i have seen 2500k that cant reach 5ghz and i have seen a 2500k that can only reach 5ghz at 1.55v. it all goes on the luck of the draw

Nope, PLL overvoltage isn't enabled. I'll give that a try when I get home and report back.

What exactly is 'false' about this information? He's simply saying that I can try PLL overvoltage, but if that doesn't work, to up LLC or vcore. Nothing 'false' about suggesting to try some different settings...

oppps my bad i thought you said It IS unusual to require higher volts than 1.45V at 5.0.

PLL overvolt was a no-go, so I had a play with LLC and vcore.

This is what I ended up with:

It's actually been running for the last hour or so; I only just opened realtemp.

That's not a bad voltage for 5.0, if it is stable there I'd be happy.
