Was an AMD oc-er before and this is the first time oc-ing Intel. Seems like 4ghz mission is completed today morning and finished stressing just now

QUOTE(hazairi @ Jul 20 2009, 01:19 PM) wow! it only needed 1.2V to reach 4Ghz? Impressive! To be exact its 1.225 in BIOS. Thinking of going undervolt but I think that's fine for me for now. Just passed 1 hour of Orthos blend priority 4 but no SS pulak. Maybe going higher after this.  |

QUOTE(OC4/3 @ Jul 20 2009, 03:34 PM) Try to change performance level to 7 or so,basically tighter performance level at given FSB net higher bandwidth and lower latency Sure mate.can I ask something btw, I never used Memset before, its just for me, a memory monitor, I usually change the timing in bios. So to apply performance level to 7, can I just straightly change it thru Memset and hit apply ? Which one do you suggest me to ? |

QUOTE(x-1o8-x @ Jul 20 2009, 04:56 PM) both BIOS and memset will do... for BIOS, a failed PL settings will result in unable to boot up to BIOS, then need to off on to reset settings... for memset, ur pc will just hang That explains why my PC hang just now, and everytime reboot after entering windows it'll hang, back to square one   Currently with PL 8 with 2.00D. Everything seems fine with 4.2ghz now at still 1.225v, will do some stressing and keep u guys up to date. Thanks bro. |

QUOTE(overclockalbert @ Jul 20 2009, 11:45 PM) i always do the PL setting in bios, as doing it in memset yields me a freezed screen once. That was what happening to me just now,after saving the settings and apply after restart, I couldnt go into windows with PL7, and it kept freezing after loading windows, at last I just reset everything in bios, start from scratch. Even PL8 only takes me to 3.8ghz.i just can't go into windows with the PL7 i set , and since memset is in the startup sequence, i only manage to go into windows when i uninstall the memset program.  Btw here's my latest ss - » Click to show Spoiler - click again to hide... « Its 1.25v in BIOS, at last I have to increase the vcore from stock. Anyway does anyone know the stock vcore for E8400 ? My bios default is 1.235v. Think this is sweetspot of the proc under low voltage, after this will try out with 2.40B. This post has been edited by mizivincible: Jul 21 2009, 12:38 AM |

Anyway mates, after we determine our oc settings stable after (doesnt matter Prime95,OCCT, Orthos) few hours of stressing, can we enable CIE,CIA2 and EIST ? Any chance of causing instability ?After enabling back do we have to stress it again just to make sure its safe ?

Decided to go with 4.1ghz daily @ 1.225v as it's still under stock voltage, (referring to VID, it's 1.2375v). Because on 4.2ghz I have to pump until 1.275v and 0.1ghz doesnt make any significant difference in real life performance.
QUOTE(x-1o8-x @ Jul 21 2009, 08:26 AM) for C1E, shouldnt be a problem in most cases... mild OC hardly cause problem when C1E is turned on... as for EIST, its automatically disabled once u manually set the vcore and multiplier... EIST is controlled by the OS, u can alter the settings in Power Options... as for CIA2, i don't know what's that -_____- Yeah the most I could go is PL8, I think that's it, as long as it doesnt affect much its all right. Anyway thanks bro So I can turn on the C1E then. Didnt alter the multiplier, just undervolt (but still considered as manually set). So do you suggest me to alter by Power Options or just leave the EIST, turning on only the C1E ? As for CIA2 I'll try to figure out what's that coz I remember I did disable it. Added on July 21, 2009, 8:30 am shouldnt bother too much about performance levels i guess... from what i see in benchmarks, they dont give overall performance boost... PL8 @ 450fsb 1500MHz easily pwns PL7 400fsb 1600MHz when i ran everest memory benchmark btw stock vcore for each proc is generally not the same... but most are within your VID  |
