i5 2500k can't even surpass 4.1 - Page 8

post #71 of 102

Internal PLL Overvoltage might not be needed here. Sure, you can enable it to see if it helps, but it's usually only helpful for extremely high overclocks.

Agree,but I would feed curiosity myself, 1.475+ vcore and not even 4.5GHz stable, worst I've heard of yet I think. Makes me think something somewhere else is causing the instability.

Is it due to having CPU Current Capability set to 100% instead of like say 140%?

No not just for booting and general status checking, extended cinebench runs and prime95 possibly, Never had an issue myself with it nor saw it ever being main culprit so can't really say for sure. But I know I always bumped it up to max it would let me in any mb I used tongue.gif

Then let's enable Internal PLL Overvoltage and see what happens. :)

now i just changed setting as suggest to CPU Current Capability to 140%.

and then slowly keep increasing voltage from 1.310.(this is the voltage with which i was able to run prime95 with stable tests with 44multiplier.)

now multiplier to 45 and gradually increasing i reached 1.410v and then i have windows memory tool...after that first time pc logged in and then i ran prime test again ..you can check from the pic.


since temps seems bit high so i just rebooted my pc ..no settings change and with same multiplier and same voltage settings i still not able to login.
this is weird as with same settings i was able to run prime95 test for half an hour without any freezes or hang and now windows wont even log in.

I have no idea if this will work, but enable Internal PLL Overvoltage. It's said that when you're overclocking and Windows won't start no matter what settings you change, the last thing to try is enabling Internal PLL Overvoltage.

yeah...
enabling internal pll did the trick..
so now im able to logged in with 1.410vs with 45x multiplier.
since last time i did primetest and temps were high ,close to 70c.
so what i should be doin?increase the voltage or decrease it?
and do the test for how many hrs if i want to be use 45x for 24x7

Pff, 70 is nothing. It's very safe.

 

Experiment with the voltage. ;) Play with it. You're a kid at play. A mad scientist. Go for it.

 

The effectiveness of Prime95's Blend test as a test of your system's stability can't be measured on time because it's not placing a constant unchanging load on the CPU. Instead, you go by whether it finishes all of the FFTs - but that's kind of difficult to do if you're not watching it. lol Generally, if you're using the default of 3 minutes per FFT, then it should take 6-8 hours. You can actually check the logs in the windows to see if it looks like it made it through all of the FFTs and has started over from the beginning. Just look for the first several FFTs again.

thx for the encouragement twocables

well enabling pll voltage really did made huge difference.with pll disabled i was not able to login as mentioned before with 1.320 volts but after enabling it not only i could login but also able to do primetest for 10-15 mins though after that i get bsods.anyhow after lot of testing and bsods and primetest i finally manage to run primetest with 45x and 1.355volts.i ran test for 3:25hrs with temps touching 70c occasianally and i think that seems stable enough imo.i wanted to run for 6hrs but my stock cooler of hyper212 started stuttering,and i guess i'm gonna need new one.

I did tried with low volts and higher volts and either i got bsods even after 40mins of primetest.
i'm really thankfull to you guys helping me to reach 4.5ghz which seems impossible as the post says can't eve surpass 4.1.

but i would like expert opinions that are tests enough for running 24/7 at 4.5ghz?
