haha, don't care is divider or multiplier, their result will be the same.AMD® Socket AM2&AM3 Overclocking V23, It has come!Bulldozer heat is around us.

QUOTE(8tvt @ Jul 9 2010, 10:36 AM) i not sure what comment is this.. not helping any.. sorry bro. multiplier often referred to cpu multiply to fsb.. to get cpu speed.. divider normally is for fsb:ram bus ratio.. let's think of this normal circumstances.. the ratio would be.. 1:2 where 200:400 200 = cpu fsb 400 = ram <-- this is where the ram can achieve 800mhz becoz of ddr u need to multiply to 2.. what if we raise the fsb to 290 by using that ratio (DIVIDER)? it can be.. (290 x 2)/1 = 580 thus 1160mhz.. can ur ram withstand this condition? so lower that ratio might HELP.. shall i calculate.. 200:333 what the hell is this.. how i calculate my ram if i were to raised my fsb.. 200:333 is equal to 3/5 how? 200/333 ~ 0.6 = 6/10 = 3/5 = 3:5 so if the fsb is 250 the ram speed would be (250 x 5)/3 = 417 ~ 833mhz.. and not only that.. u need to play with the voltage and the advance timings.. i just mean no need care about the motherboard is using multiplier concept or divider concept. although their implementation are different, but they will give same result. just like: base clock x dram multiplier = dram clock 200 x 2 = 400mhz base clock / dram divider = dram clock 200 / (1/2) = 400mhz and the multiplier or divider, usually will be in ratio form, that is: base clock : dram clock = 1:2 |

QUOTE(8tvt @ Jul 9 2010, 12:14 PM) no offence.. newer amd phenom architecture using dram multilplier.i donno where u get that ram multiplier.. what about other ratio? i'm sure it's derived from the fsb:ram ratio.. it's actually 1:2 not just multiply by 2.. just that the answer is correct because it was divided by 1.. normally we refer the multiplier to the cpu.. older amd athlon architecture using dram divider. |

QUOTE(8tvt @ Jul 9 2010, 03:18 PM) some board have 1,2,3,4,5,6 or what ever should refer to.. ya, its all about maths.1- 400 (1:1) 2- 667 (3:5) 3- 800 (1:2) 4- 1066 (3:8) 5- 1333 (3:10) 6- 1600 (1:4) what ever it is... it's still came from that fraction.. 1- 1 2- 1.67 3- 2 4- 2.67 5- 3.33 6- 4 crazy jargon same like fsb and htt.. so just multiply that value with fsb will get the ram speed (don't forget to multiply by 2 for ddr) easier isn't it.. but lost the concept.. but don't know motherboard implement multiplier logic circuit or divider logic circuit. |

QUOTE(shinjite @ Jul 10 2010, 01:11 PM) With new manufacturing process nowadays, both Intel and AMD can clock at high speeds~~ hey, your cpu really cool. my one idle also 40c. Those were the days where AMD 3Ghz was like godlike to achieve haha For Intel, it was 4Ghz Now....both can easily do 4Ghz (performance aside, switched places) haha I think my WC setup not that optimised....stock speed 2.2Ghz at 1.1V, idle at 28c load at 38-39c. Any comments? |

QUOTE(shinjite @ Jul 10 2010, 03:26 PM) I see, thats a lot of difference wao, you should have a good cpu cooler and good air flow casing.Currently me priming small ffts (heats up the CPU a lot more than blend) And also testing my Crucial Ballistix Tracer RAM, which just came back from RMA recently, running at DDR1066 at 2.1v (Its hot weh!!! although LED blink blink ler) My OCZ Reapers keep aside first Below is the screenshot Full loading at 40-41c (non aircond, freaking hot today ~_~) [attachmentid=1669023] |

QUOTE(kimurastanley @ Jul 11 2010, 09:36 PM) so my situation is maybe the kingston DDR3 1333 value ram prevent the base clock go further than 250mhz.Setup: CPU 250x11.5=2875MHz HT, NB~2000Mhz Ram ~1322MHz(Stock 1333) CPU T full load Max= 55 C Voltage all at default stock But system still crashes so that means the proc cant go more than 250MHz? i also have kingston DDR2 800 value ram that prevent my pc base clock go beyond 265mhz. |

QUOTE(AMDAthlon @ Jul 11 2010, 11:27 PM) Yes..IGP really holding back the processor..i Suggest you LEND ur fren GC first and see if it really IGP culprit..but most of the time yes becos that processor is quite impossible to not reach 3.8Ghz..at least.. hey, is the IGP clock got relation with the base clock?Or maybe you should buy aftermarket cooler |

QUOTE(cloudwan @ Jul 15 2010, 11:15 AM) Aiyohhhh really hard to get 55c for 4ghz, even with the Noctua i'm using on push/pull also sooo hard.. consider to lapped it? Been reading a few articles about HSF and got me thinking if the high temp is because of the design of HSF not being so compatible with AMD chips like maybe the heatpipe orientation or something.. |
