Wow....you use 1.44Vcore @ 3.2GHz?? shocking.gif

I think its due to the voltage drop bro.I cant go beyond 3.1Ghz below 1.4Vcore. sweat.gif

no such thing.
i already test all proc and confirm can hit 3.1GHz with 1.23V
just checked my test report,
your proc is 0737BPMW 0235
1.23v pass 3.1G pi 1M test without issue
TA690G voltage drop is not up to that much,
i'm using the same mobo to test all proc wink.gif
kindly check your settings again icon_rolleyes.gif

I want to ask a simple question , planing to buy AMD X2 4000+ Brisbane but will it able to compete with AMD X2 5600+ or 6000+ if I overclock it to 3.0Ghz ?

I plan to invest more on graphic card maybe Ati 3870 par with AMD X2 4000+ but quite worry it'll bottleneck with the graphic card so I plan to overclock it.

It will be hard for a brisbane to compete with a 6000 even at 3.0Ghz, but maybe with a 5600. The problem is that brisbane is at a 0.1Ghz disadvantage due to cache latency, and also those 2 processors have 1mbx2 cache while brisbane only has 512kbx2. Clocked 0.2Ghz higher than the 5600, brisbane might just pull up even with it.

Mine is stable at 5-3-3-3-2T @ 1066 2.55V.

Have anyone use memset 3.4 Beta 3?
Theres a lot more settings in it. thumbup.gif

i use beta 1 before tis.. almost same like beta 3.. maybe u shud try to look for 3.4 finale... almost same..
acording to DB , 3.3 is the best.. so chose wut u think is the best

hoho.. brisbane is quite a good choice for a budget user. My advise is, try find a good RAM bro. I dont think brisby(even at 2.8Ghz) will bottleneck your GC watsoever. Even you can hit 3.0Ghz stable if you're lucky enuf. And the best part is, it's only rm210. brows.gif

Just my opinion.
If you wan oc, you need a lot of stuffs. smile.gif

1st: You will need a decent cooler.
2nd: You will need a good ram and mobo. Ram speed slow performance drop.  Mobo just go for Biostar TA690G. thumbup.gif
3rd: You will need a good PSU for overclocking and support 3870.

These are all i can think of. Bottleneck or not for this combination not sure tongue.gif

Thank you for the reply.I had limited choice of hardware to get at my area.It doesn't have Biostar TA690G , just only Asus M2A-VM.Cooler ,Cooler master stuff including thermal paste.Not much I could get.

I just want a decent hardware which is better than P4 3.0Ghz and doesn't bottleneck with the current graphic card.Maybe getting a 3850 for normal gaming.
Just want to ask , an AMD x64 4000+ 2.1Ghz stock speed can win P4 3.0Ghz at lease 10% ?
Can I refer with this chart ? http://www.cpubenchmark.net/ ? or maybe a better chart I can refer ?

Why? bcoz at 2,835 i only use stock vcore and 945Mhz 4-4-3-8 ram @ 2.2V. If use at 3.1 Ghz, i've to add 0.075 vcore to make is stable AND have have to loosen timing to 5-5-5-12 at 1085Mhz @ 2.6 vdimm which only results in littlte gain of performance .

So, in daily use i chose 2.835Mhz with no additional vcore added. Some time i go for 3.003Ghz at 1.35V and 1000Mhz 4-4-3-8 @ 2.4V which results better super pi value than 3.1 and 1085Mhz 5-5-5-12 icon_idea.gif .

I sayang my hardware woo. Don want to push vcore for daily usage. biggrin.gif

are u lapping your cpu?
put the sand paper on the mirror or glass.... and lap it (read from a guide in ocmania)
that is the perfect contact u can get... but i never done it before...
it will be awesome if someone can show any different temp between lap or not lap ... =)

polish only....it's quite hard to lap because of the pins...if for 775 ..then it will be easier coz no pins

on another note, its actually easy to to lap Am2, shine itself wont do much good because basically what you want is to flat out the non-flat surface.

AM2 pins are rather sturdy and dense, just put 2 fingers to the pins and start lapping, the pins wont bent easily...

its hard to explain how, take this for example, u drop a baloon on 1 needle and it will definately pop. But if MANY needles are arranged, they wont be able to break the baloon, more like pressure is balanced out to the pin masses.

Anyways, you dont have to use too much force, just gently slide the proc, its easy to lap.


Added on December 19, 2007, 4:47 pmoh, and start from 1200 grit, for mirror shine go for 2000grit

from what i tested... i know it is not ram limit me... but the cooling is the one ...

we are going no where around 3.4x with air cooling...
but at this speed is the most stable clock the cpu can gain....
i can boot to windows with 3500mhz but cannot even prime...
pump more vcore... pc auto shutdown...
from my exp .. that is abit uguru is protecting me from killing the cpu by direct shut down the pc... the cpu temp cannot maintain at certain level...
and it direct jump to to the cpu limit set in bios... something like your temp is 60'C and sudden go to 80'C

only water cooling can go beyond that limit with unstable system in high clock =P

you're wrong..i can reach 3.6 with air =D

i know this...like one stick easier to break and many sticks hard to break

There is a difference, depending on how flat the IHS and heatsink surface originally was. Shininess comes secondary, not much effect between a perfectly flat, unpolished surface and mirror finished, also perfectly flat surface. I did a comparision a few years back while using my first 478 system, got a 3-5 degree drop. With the addition of a direct intake duct I could keep the processor within 5C of ambient at all times. And that was a processor with power consumption similar to the lowest end AM2 X2, 65W version.

I will be doing a long term comparision using some K8 stock heatsinks, will put up my results in a few months time (have a lot of comparisions to do).

4000+, m2ne, team elite 667, stock hsf
i saw different vcore in bios, everest ultimate and cpuz.. dont know which is the accurate one..
In bios: 1.31v
In everest : 1.35v - 1.36v
In cpuz : 1.168v - 1.184v
