Re: [OC] safest OC for a 2500k, on a Asrock p67 extreme4 gen 3? I've noticed that whenever I use offset, unless it adds voltage, it causes errors in prime 95 after about 20 min, always on core 0. is that supposed to happen? if I dont use offset I get voltages of 1.256-1.272 most of the time, but can spike up to like 1.32V for a second or two then drop back down. and trying to used fixed voltages always causes BSOD not matter what settings I use with it, but I think that may have something to do with my wireless card, always disables it on next start up when that BSOD happens.
Am I doing something wrong or is my chip just one that needs more voltage? | |

Lagrangeville, NY | What you are seeing is vdroop, Say you set 1.3, under load, you will see more like 1.25, this is because of as I said vdroop, you are setting the MAX voltage it will *ever* hit, not the load voltage, when the cpu comes on and off load you get spikes as the VRM can not adjust the voltage in .000000000000000000000000001 seconds...
If you are getting errors, you likely need more vcore, core 0 is more hungry for voltage than the others... welcome to overclocking.
Like I said, everyone is saying o I get this that... it all depends ON THE CHIP. Yours might be golden, or it might be meh, or suck for top end overclocking... you will find out as you try to overclock.
1.27 is still pretty low and you have room to bump it up. | |

it has to do with VDroop Try setting Load Line calibration to regular. If that dosent help set it up to the next level (high i think it is) You gotta play with it and find the setting thats right for you. I have my LLC set to regular with a +0.60 offset and im pretty solid at 4.5 Ghz Also, common practice is to get your machine running stable at stock. Then OC, then install extra cards such as wireless card. but none the less, you are where your at now so I would just continue on playing with the settings (LLC and Offset V) Aside from the Clunk web site I recommended which is great for the basic and first OC I know there isnt much info there for offset . Here are a few sites with lots of info for you. » forums.overclockers.co.uk/forumd···php?f=89» hardforum.com/forumdisplay.php?f=80» www.xtremesystems.org/forums/sho···ormationAnd again Matt is correct you have plenty of room to bump up the VCore if need be --

Ok, thanks for the info guys. I've got it set to auto right now, not seeing any errors or anything so far, tops out at 1.288V when prime95, 1.32V on minecraft. I can deal with 1.32V, not too bad i've seen some needed 1.34 or more for 4.5Ghz so mines not too bad. I'll play sround wit hthe vdroop and voltage settings. and if the spikes are just from coming off a load and the vrm not adjusting instantly thats fine, beats having it at 1.32V all the time.
my mobo uses different terms for vdroop and llc and so i'll read the manual and see if it says whats what in there. | |
