Hey guys Im new to overclocking, I recently built a i3 540 system with a GigaByte P55-UD3 board and it overclocks fine up untill Bclock his 170MHz, Any tips on what I could try to get it to run any faster? Temps are running about 33C idle and 45-50C under load. Thanks
I have a coolermaster v8, im at 1.312V Core at 3.9GHz (23x170) I will need way more voltage then 1.3 for 200block. I cant find IGP setting to check to make sure it is off, any idea what its under in BIOS?
I would bump pll and vtt a single notch and make sure qpi is at least twice of memory - in fact even with memory at 6x I would set qpi at 16x
Have you tried lowering your cpu multiplier to see if it's chipset or cpu limited? And I'm assuming you have at least ddr3-1333 memory and memory voltage set to 1.65 if the modules require that (check spd settings)
Ok so that means my BIOS is putting to much vcore in my chip now, Maybe i need to update my BIOS to get that IGP setting I cant find it anywhere currently, I have bios revision f4, anyone know if that supports the new i3's?
Ok I made some progress. I broke 4Ghz, barley. But not without my first scare of overclocking. Let me back track for anyone interested in my first quest in overlocking.
Up untill now all I had to do to OC was just keep upping the bclock, 5 or 10mhz at a time. Bios auto set all volages and no problems from the memory as it went up. Nothing went wrong till I tried to go past 170bclock, but then the BIOS detected an error and reset to defualts and everything was fine.
Fast forward to Sunday and I'm trying to run bclock of 180 with a CPU multipler of 20 (23 is stock setting) as neiroatopelcc suggested to see if it was mboard or cpu that wouldnt go past 170x23. Well I try to boot and it fails, no output to the monitor and the keyboard didnt work. No automatic BIOS catch to save me and reset to default. This time it acted like it booted but just hung up. I tried restarting it a couple times with no luck. I had never read or heard anytihng from anyone about a situation like this so I pulled out the mb book to find out how to get to factory defualts. I saw a picture diagram with a reset CMOS jumper graphic. I looked on my mb, saw the jumper, and got out a screw driver and put it on said jumper for a count of 5 seconds. I turned my rig back on (with my fingers crossed) and it worked, back to standard settings in the BIOS. I tested the system a bit, two restarts worth then went back for 3.9ghz which ran stable till today; when I decided this morning to try for 4ghz.
How I did this was by tweaking them memroy settings. I changed the memory multiper from 10 to 8 which lowers the memory freq from firstname.lastname@example.org (170 x10) to email@example.com(175x8) and thats what I'm typing on now seems stable so I want more till I get up to psychos rig at 4.6ghz. My temps are at 34 as I type this with a max of 48 in the hour plus Ive been on.
So 4 questions for anyone gracious enough to help me out,
1 Since I still havent flashed my Bios is the IGP running this fast too?
2. If yes, should I worry?
3. Should I stop pushing it till I flash the BIOS and disable the IGP?
4. Does this mean that my Ram isnt stable past 1700mhz?
