Intel E6600 Overclocking...
Hey guys , wonder if you can help me....
Im kinda new to Ocing and have tried overclocking my PC , from googling I came across this site : http://www.xtremesystems.org/forums/...d.php?t=115217 I have read many other CPU ocin'g guides and heres my specs : E6600 3GB DDR 2 667 Ram 8800GTX Asus P5B Deluxe MB 700W TT PSU XFI platinum now here is where I need help , according to what I have read , I should beable to hit 3GHZ....or overclock the FSB from 266 to atleast 333 well....If I go into my Bios settings (have latest asus bios) and I try change my FSB , to lets say 300 , and I either leave the vcore on auto or raise it to 1.875V....as soon as I click "save settings and exit" my pc IMIDIATLY turns off (as if the electricity tripped) .....after this , the PC will not turn on for atleast 1 minute. I have tried setting the FSB to 286 and not touching ANY OTHER setting and the same result follows. I have a Blue Orb 2 CPU cooler..... am using a TT Tsunami case , with plenty of fans etc..... PLEASE can someone give me some advice? I have read everything about my MB and overcloking.....it runs perfectly fine though : 3D mark 06 = 11,000 thanks for the help porky- |

Whoa there buddy, 1.875v on the CPU??!? Thats like at the point where you'll be killing the poor thing.
Now that page on xtremesystems is only a reference. And there is a reason why its called xtremesystems. I suggest the only things you lock down are the PCI-E bus to 100mhz, PCI bus to 33mhz, and disable spread spectrum. Dont mess with ANY other voltages. 300mhz is a cake. Just dial it in and your set. P.S, 3 sticks of ram is not the most ideal.

Are you sure everything is on AUTO that should be? I would try starting over by clearing your CMOS, locking the specific area's I mentioned in the previous post, and setting it to 300mhz.
You didn't set a divider did you? I.E dram frequency. If this doesn't work, try it with only 2 or 1 stick of ram inserted. |

ye , I changed ALL settings to defaults......
and I just upped the FSB to 287mhz.....pc just turned off  wot a divider? with everything else on auto.......ill try with 2gb ram...but will that make a diff like that? Last edited by porky; 03-08-2007 at 04:26 PM. |

Clear your CMOS according to your motherboard's manual.
Just leave where it says DRAM Frequency, on AUTO if you haven't already. Might be, odd number of sticks will sometimes cause problems when it comes to overclocking. What model of ram do you have by the way? Could be the limit of the ram. Remember though...a jump from 266 to 300 won't exactly result in a huge performance boost. Stock speed is stability.. |

That guy's running PC28500 with an X6800 CPU in that forum. If you tried to set your system up like that, it's no wonder it has crashed. You need to go back to square one, as Mr.F said, using two matched sticks. If you can wake it up, load in OPTIMIZED DEFAULTS. Stop there and get back to us. You need to get your sytem running again before you start tweaking around. Good luck.

ok , update....
PC works fine...... only if I try to OC it , it doesent even turn on...have to wait a few minutes to get it working again.... Im using this ram : http://www.corsair.com/corsair/value....html#ddr2dimm I have the DDR 667 1GB version...... as I said , even if I underclock it refuses to boot (turn on) |

OK...I think I have found the problem.......
Basically whenever I overclock , and I click save settings in my Bios my pc just turns off.... no matter what , (disconect plug...) my pc will not turn on again afterwards for atleast 5 minutes....... when I change the settings and my pc turns off , I hear a click click sound (electrical , asif something is sparking) Is it possible that its my PSU???? im running my 2.4ghz E6600 at 2.7GHZ atm (ram speed is 600MHZ) when I did this OC , as soon as i clicked save settings it turned off as usual....but when I eventually turned it back on it went to windows etc...... now should I leave it like this...or could this indeed be a faulty PSU (seeing it wont turn on half the time) thanks for the help...gettin their (Mr Ferrari , did exacly wot u told me , FSB 300 , other one 33mhz and left everything else on auto...still turned off though , but atleast went to windows) |

ok....
CPU is at 3GHZ fully stable (havent tested further) Vcore voltage is 1.375 mem voltage is 1.9v all other voltages are set on auto. fsb = 334 temp is 58c idle 73 deg under prime 95 burn test (is this too high?) think I can go further??? thanks for the help |

Damn! While I'm no expert, I run myself with the same thing you have, 667 RAM and a 2.4 Core 2 Duo, and I'm running it at 3.0GHz, and I don't go over 44-50C with a prime95. I run at 25-35C normally without the torture testing. I think once you get out of the 60C range, you have a bit of a cooling problem. Also, since you're running a dual core, instead of running prime95 twice at the same time to test them both out, just use orthos.

Looks like you've got your RAM maxed out...I doubt you'll get a whole lot more out of value select but you might squeeze a few more mhz.
Whoa, yeah, those temps are too high. You've probably got some thermal throttling going on above 70C (lowers CPU speed to reduce heat). I'd back off on the overclock (speed and vcore) so your temps stay comfortably below 70C.

er , speed fan.....
upped speed to 3.2ghz stable , vcore is 1.35. max temp is now 72degrees c will lower vcore more (seems whenever I lower it , it lowers heat too.....) what symtoms would i see if my vcore is too low? **edit...ok saw the symptoms of too low vcore  ....lowered the freq to 3.2ghz (was 3.3ghz) idl temp is around 47degrees and max temp using prime 95 torture test is around 62 degrees....that too hot?? thanks for the help guys Last edited by porky; 03-09-2007 at 05:15 PM. |

Use Intel Thermal Analysis Tool to get true 100% CPU loading. Max should be 60C TCase / 75C TJunction.
Using Orthos... TCase Max 55C / TJunction Max 70C Throttle Temp: 65C TCase Disclaimer: These are the specs I have been told. I have not done any testing of my own. Last edited by Gene1; 03-09-2007 at 11:25 PM. |

i agree CORSAIR make's good memory but the ''value select'' line is not geared towards o/cing. |

Thermal Analysis Tool. The limits have already been posted, refer to Gene1's post.
http://www.pureoverclock.com/download.php?det=6 If you want to push the FSB any higher than 333, you need to get faster ram. You ARE prepared to buy new components if you burn any out trying to overclock, right? |

GLC - yep and thanks 4 the link......
ok...i turned everything back to default......so pc is runnin at 2.4ghz everything back to normal....and I then wanted to see the cpu temp usin prime 95...at stock speeds the temp is 53c under full load , that with case OPEN..... that too high?? **TAT doesent want to work...it opens then imididiatly closes (running as admin) heres a sc of my system idle everything at stock , using a TT Blue orb 2 and a TT Tsunami case : http://img171.imageshack.us/my.php?image=ggnc0.jpg this is at load : http://img181.imageshack.us/my.php?image=22np8.jpg both are stock everything no ocercloking remember...when I oc to 3.2ghz I get a max load temp of about 74c Last edited by porky; 03-10-2007 at 11:04 AM. |

if you plan on getting more out of that chip and having lower temp's i would suggest better RAM and cooling.

surely a Blue orb 2 is suffiecient...iv seen all benchmarks and im running hottest here for some reason (although perfectly stable at 3.2ghz)
also atm I dont plan on gettin faster speeds...I just want cooler temps for the cpu...soo ram doesent matter anymore...just cooling for the CPU... perhaps my blue orb 2 aint on the chip properly? |

another factor might be that there are C2D chip's that have a concave heatsink.

Thats not a stock heatsink - its a Blue Orb 2.

I think he meant concave cpu heatspreader.
Is there a large difference in temperature between the case side panel being open and being closed? If so then you probably have a case airflow problem. And the blue orb 2 isnt all that great of a heatsink, if anything marginally better then the stocker. CoreTemp is also another good temp proggie. |

no diff between if my case is open or not....
could this be because whoever built my pc did not use good quility thermal paste...could that make a big difference? Iv looked at reviews , and they say the blue orb 2 is amazing at cooling??? am I wrong here...if soo....what would u guys suggest...wouldent mind even goin water coolin....but wana exaust all other alternatives first (also...my pc is very stable at 3.2ghz...but it goes upto 75c under full load....soo should I just not worry and keep it at 3.2???) (HAVENT TESTED HIGHER THAN 3.2 BTW) also if I touch my CPU heatsink its actually not hot atall.....maybe speedfan is telling me wrong temps?? heres a review o the BO2 http://forums.techpowerup.com/showthread.php?t=5351 Last edited by porky; 03-10-2007 at 03:27 PM. |
