if i wan to go for 3.6Ghz.. u guys think is it better to
343 x10.5 or 360 x10 how does a multiplier affect the stability of the proc? |

QUOTE(VT-Ten @ Jul 13 2009, 11:32 PM) i would personally opt for higher fsb if the mobo permits it. my mobo is capable of doing 500.. juz see whether i can hit it onot..   QUOTE(-pWs- @ Jul 13 2009, 11:36 PM) Here is mine. from yr picture.. looks like yr proc stepping is same as mine.. it shows R0 in cpuz.. but it shows E0 in Everest.. anything to clarify me?3600MHz (400 x 9) PL 8 @ Stock VID [attachmentid=1076795] -pWs- anyway, nice clock u got there.. i might try 400x9 if i get pass 360x10.. waiting for my cooler to arrive.. |

QUOTE(vicdd @ Jul 21 2009, 06:10 PM) yeap, in ac room, ambient temperature is about 24 degrees..im using OCZ vanquisher cpu cooler mah, its really cool, max load only about 51 degrees on ac also no wonder.. cz even with very good coolers, will hardly reach 34 on idle without air cond.. cz we need a minimum temperature difference in order to have a heat transfer (study too much heat exchanging..  Added on July 21, 2009, 6:12 pm hehe, i know its obsolete already, still keeping it till next time when i upgrade its still a good mobo for OC provided you update the bios to get better control  )with the ambient temperature at malaysia, hardly reach 34 unless u stay at genting or cameron lo.. tat's y i suspect u use ac.. anyway, good OC u hav there..  |

lol.. before OC i can idle at 38/37°C.. now after OC (stock cooler) idle min 40/38°C.. but on load will be different..
stil waiting my 3rd party cooler to arrive..  anyway, how u guys remove the stock thermal paste? just use a ruler to scrap it out? |

QUOTE(vicdd @ Jul 22 2009, 12:03 AM) depends on what brand la, cap ayam brand will not get you anywhere, (rather just keep using stock cooler) where as a good one really cools down your cpu overclocked OK, good luck bro.. i m still waiting for my cooler.. now stopped at 3.2Ghz with stock cooler n voltage..if you are planning to overclock, aftermarket cooler is the best bet, you dont want your cpu to fry of rite? Added on July 22, 2009, 12:06 am haha, yeap, in Malaysia, ambient temp is 39-40 degrees, impossible for the cpu to be 34 degrees in idle mode lo hehe im still trying to push to 3.5 ghz with stock voltage, but still no avail..now trying to adjust lower multiplier with higher bus speed will keep you guys updated mine is an E7400 btw.. |

Got a nub questions, I just using normal 2x 1GB kingston 800mhz ram on Gigabtye G41m-ES2L mobo. Issit better to OC it to 333x 10.5 or 400x 9 ? And do I need high performance RAM for OC-ing? Currenty in cpu-z it shows I'm using 1.2v and running on 266mhzx10.5.  400x9 is better.. |

i juz installed xiggy RS to my E7400 yday..
but my idle temperature for Core #1 is 40°C n never drop below tat.. Core #2 drop to around 30~33°C.. currently 3.2Ghz at max load 58°C is that normal or i din seat my HSF properly? |

QUOTE(JoBigShow @ Aug 27 2009, 08:20 PM) In 3 days of hard research on google, how does this compare to the simple LinX? I learn that 'Blend' is the more suitable candidate for trying to find the stability in your system becoz its more practical. This is bcoz 'Blend' (stressed both cpu and ram) works how PC should work, by applying both usage of CPU and RAM simultaneously. Small FFT's is a more theoretical approach if u want to know your proc more closely/intimately. (used a lot in OC contests) Large FFT's is also theoratical if u wanna know the maximum level your whole system can endure, which stressed mostly everything in your system like PSU, CPU, RAM, capacitors of the mobo, etc. Beware, this one heats the pc like hell, my cpu temp reached up to 75c+ on load even though i have aftermarket cooler: Artic Cooling Freezer Xtreme. Large FFT's is the favourite of hardware manufactures to test their products to the max. hope anyone else can verify me on this... |

QUOTE(JoBigShow @ Aug 28 2009, 08:33 AM) LynX measures the CPU performance in Gflops. (It's something i havent heard of apart from the more familiar Lucas-Lehmer test.) wow.. is it? not aware of tat.. I din use prime95 cz i noe its time consuming and straight using LinX..This pretty popular among russian overclockers. LynX stressed the cpu way more than Orthos and Prime95. It is claimed that LnyX saves more time bcoz 1 hour of LynX stressed test is equivalent to 6 hours of stressed test performed by prime95. Bcoz of this, it is known that LynX raised up more higher temps than u get when running 'Large FTT's' on prime95. e.g 10c-15c more! So u have to be careful when leaving u'r PC unattended when running this software. (Large FTT's on prime95 already makes my cpu really hot, i will expect this software to raise my cpu temps up to 80c, even with my Artic Cooling Freezer Xtreme.)  Here's a thread on Lynx from the original creator: http://www.xtremesystems.org/forums/showthread.php?t=201670 I'm gonna try this 'linpack interface' soon... I stress my E7400 @3.2Ghz for about half an hour and hit the max temperature of 58°C at night.. |

QUOTE(JoBigShow @ Aug 28 2009, 06:58 PM) Maybe those people who got their temps very high because: yup.. i OC to 3.2Ghz and stop there last time bcz i was still using stock cooler.. and yes @ stock Vcore..1. using stock cooler. 2: OC more than 3.6ghz on C2D 3. OC'ing Quad proc up to 3.4ghz+ 4. Set their Vcore more than 1.45v+ (Increase in temp relevantly due to increase in voltage/vcore.) Your e7400@3.2ghz doesn't get really hot bcoz you still can use stock vcore @ 3.2ghz. My E7400 does. It's when u OC up to 3.6ghz+ is where u'r in business. I used set my vcore on 'AUTO' when i was still OC'ing @ 3.5ghz (334 x 10.5) a month ago. (now maintain around 1.3625v @ 3.6ghz~3.8ghz, can topup to 4.0ghz+ if i want, but somehow i luv my proc too much to push it that high) Have you encounter any bugs/problem in LynX? Unless u have the latest version: LinX 0.6.2.1 (I will download LinX soon to try it out later) Nywayz, there's a thread on LYN about LinX: http://forum.lowyat.net/topic/892376 now i'm planning to push it to 3.6Ghz when i'm free.. not going for 4.0Ghz anyway.. can share yr settings for 3.6Ghz? i just downloaded 0.6.2 today and will giv it a try later tonite.. I'm using 0.5.9 before this and never encounter any bugs so far.. (or i din notice it ) |

QUOTE(JoBigShow @ Aug 28 2009, 07:18 PM) 90c got such thing? Buying a proc at the shop really like playing blackjack or lottery, its all starts when the salesperson picks up your proc randomly among other processors on the shelf. It seems in this game of "processor lottery", u looked unlucky bro... Statistically-wise, some say the probability to get the 'unlucky' chip from Intel is less than 2/10. I read some people(usually highly superstitious geeks) up north in mainland China will choose a proc by their serial number, apparently they want the s/n which has a lot of '8's in it to avoid getting the 'unlucky' chip. You tell me... then they will avoid 4 4 4 or else their proc might die.. QUOTE(nidzamputra @ Aug 28 2009, 07:21 PM) mine also using linx 0.6.2 today to stress my E7200 @4.0ghz 1.32v wow.. tat's insane.. what's the temperature before using LinX? how long u stress yr proc?hahaha..the result temp so high for both core...reach 92'C then auto shutdown...using thor's hammer cooler... |

QUOTE(JoBigShow @ Aug 28 2009, 08:11 PM) Yes, @ 3.6ghz: okay bro, thanks for the tip.. will try out when i'm free!400 x 9 fsb; 1.336v~1.344v IDLE : core0 = 31c core1 = 34c LOAD: core0 = about 60c core1 = about 58c No OC on Dram bcoz the increase is minor in terms of performance. (but sometimes I increase my 800mhz by 20mhz and 400fsb by 10 to keep that 1:1 ratio, e.g 410 x 8.5 fsb @820mhz DDR2 =3.485ghz, fairly stable depends on the mobo and cpu) Make sure u disable most of these settings when OC'ing the cpu: Intel® Virtualization tech, CPU TM function, C1E, and more importantly disable Intel SpeedStep ™ tech And of course I got aftermarket cooler: AC Freezer Xtreme I recommend that 1.336v~1.344 is enough for 3.6ghz on a E7400 chip. If not, then just increase OR decrease in increments. (Make sure it's 1.336v-1344v in CPU-Z, in BIOS u might need to set the vcore slightly above 1.336v) Remember this is only my opinion based on my e7400. I hope your E7400 is not that different. Addtional info: @3.8ghz 400 x 9.5 fsb; 1.352v~1.3625v @4ghz 400x10 fsb; 1.3600v ~ 1.3625v (i try not to go above 1.3625v since its not recommended by Intel when OC on 45nm chips) Even at 1.3625v@4.0ghz its seems quite stable |

juz done OC to 3.5Ghz
333x10.5, Vcore set to auto, CPU-z shown 1.280V under this warm morning condition, LinX stress test completed with no errors for 20 rounds.. max temperature hitting 73°C with average temperature of 71°C.. Using xigmatek Red Scorpion only.. dividers set to 5:6 to get 333:400.. anything else to set, mayb to lower down Vcore? or go ahead to 400x9? |

i think 4.0Ghz will be too much heat for my RS to handle.. i'm happy to stay it at 3.6Ghz if my temperature does not exceed 70°C
btw, using 360x10 and 400x9 will have any difference in temperature? i think higher FSB = higher voltage = higher temps rite? no? Added on August 29, 2009, 2:13 pmhave a question here.. i set my Vcore to manual and set it to 1.26V but after i boot up, cpu-z onli shows 1.232V.. y huh? Added on August 29, 2009, 2:54 pmlatest setting in bios i pump it to 1.28725V cz not stable in low voltage.. but cpu-z still show voltage reading between 1.216V~1.232V This post has been edited by farscope: Aug 29 2009, 02:54 PM |

QUOTE(JoBigShow @ Aug 29 2009, 07:31 PM) I use to OC'ed my chip to 3.5ghz (334 x 10.5) when i was using my old 667mhz DDR2 to obtain that 1:1 ratio. yup.. thx for the info anyway..I set my vcore to 'AUTO' and running stable. 360x10 and 400x9? If u'r concerned about temps u should opt for the 360fsb, but if u have DDR2800mhz and u want that 1:1 ratio, u opt for 400fsb. i think higher FSB = higher voltage = higher temps rite? no? That's why Intel created Core 2 Extreme procs, they have multipliers unlocked up to 14, this way you can maintain a low~mid range FSB but still attain high Ghz, meaning normal temps but high performance/ghz. i set my Vcore to manual and set it to 1.26V but after i boot up, cpu-z onli shows 1.232V.. y huh? It's 'v droop'. (It's an Intel specification designed to protect your CPU from overshooting voltage), i think u should trust your BIOS latest setting in bios i pump it to 1.28725V cz not stable in low voltage..but cpu-z still show voltage reading between 1.216V~1.232V Man that some big ass v droop! if u Google around, there's alot of threads about this issue. usually corcerned with enable/disable LLC. Well I'm not familiar with EP45-UD3L.... the drop is big, tat's y it concerns me.. in BIOS i set it as 1.28725V because that's the voltage i can pass LinX without encounter errors.. but cpu-z shows voltage between 1.215V~1.248V.. however, the temperature drop about 5°C compare to the time when i use "Auto" With Auto Vcore, i got 1.28V~1.31V in cpu-z.. not sure bout BIOS cz i din check it.. but even thou i set 1.28725V in BIOS, when i check the voltage reading in bios, it shows about 1.26+V any idea?Added on August 29, 2009, 8:20 pmah, talking bout LLC, i remember mine was disabled.. should i enable it?

if LLC is on, vdroop wont be much..
i had my LLC off.. so my Vdroop is alot.. still thinking should i enable LLC to lower down my bios Vcore or just stay it with LLC off.. |
