i5 2500K @ 4.8 GHz oddities
I am a pretty amateur overclocker, and this is the first time I've really taken it seriously, so I'm trying to hit 5 Ghz on my 2500k with AsRock P67 Professional (basically has all the bells and whistles for OC'ing)
I haven't currently went for the 5 Ghz run yet as I'm getting some strange things happening at 4.8 Ghz. It appears to be quite stable as I've survived probably a dozen reboots and about 2 hours of Prime95, as well as multiple SuperPi runs, but Prime95 is giving me issues.
my current settings are:
Multiplier @ 48
Speedstep (turbo) off
CPU current limit @ 300
CPU core volts bumped +0.195
RAM downclocked to DDR3 1600 (from 2133) (altho CPU-Z is reporting it only at 800 MHz) @ 9-11-9-28
Thermal throttling off
everything else on auto
According to CPU-Z it's only loading the CPU up to around 4 GHz, it'll hop around between 39-42 multiplier. Temps aren't the issue, my V6GT is keeping me at 68c max under load, and a 29c idle. Weird thing though is that SuperPi will load it up right to 4.8 Ghz on any size run I try.
Should I just disregard it and carry on with my march to 5 GHz or is it showing instabilities already? And I'm concerned about the RAM, why CPU-Z is only reporting 800 Mhz. Stock its DDR3 2133 9-11-9-28. Prime95 is 64 bit version 2.65
disable everything but the thermal thingie.
add more jucie to eveything else, little by little.
put ram on lowest divider.
try odd multi?
DDR = Double Data Rate. CPU-Z shows real frequency, not the doubled rate.
As for the overclocking it went well. I was able to hit 5 ghz butnas soon as I did I had to leave for the evening. So tomorrow I hope to be able to stabilize everything. All I had to do to hit 5 was just reduce my load line calibration and actually reduce my volts slightly. Tomorrow I'm gonna try downing the volts little by little, cuz at max load it goes up to 1.42 volts. It's at 1.2 at idle.
Very happy that I hit 5 though. Seems like I got lucky and got a good 2500k. I'll save my 5 ghz bios as a profile in my bios and probably run at a tamer 4.4 for general use
how can it be the volts when your not running hot?
I would take your fbs and max it out as far as you can with the cpu on stock speeds to find your max fsb with ram timings, volts and etc, then reset your ram and etc to stock and take your cpu up the max stable like your ram, once you got that, work with them both for a higher clock and stable system with the ram and cpu running less and better effective, which will = :punk:
