of cz its low..tats y i cant do anythg much....but i stil hvt jack up max oc...nw running oc 3.0 stable pi test..not yet prime....

Try borrow some ddr 550 g.skill from any of your friends to see how far your proc can go. If there any. About 2.6v is enough for tccd. I doubt the mobo will stable at higher clock with prime if you play with the vcore due to fluctuation.

I think its your mobo fault. The vcore fluctuate. This problem kinda shit for oc. My old asus P4c800-e also have the same problem there long time ago. Nearly same value there 1.488v if i still remember. But unfortunately i think there no vdroop mod for your msi mobo. Try google it.    Buy the new amd64 or P5 if you are rich lol

for ur information..cpu-z always show low voltage compare with what u set in bios 

  wa... start oc ur proc liao...

ur mobo supprot 1T? use that..

2.685v is shitty low... u try find latest bios to see wehter they mod it to allow u bump up d voltage..

siauann: if u read around
more extreme overclockers has jacked up their Vcore to at least 1.6Vs
but during load, the Vcore alters and sometimes even flactuates to 1.4xVs
which can cause instability

oh...icic....i been thru roughly ths thread n dint realise all set at 1.6v cz wat i knw is the stay as low as u can....

prob is all my fren not a pc enthusiast...thy dun own such a gd ram..
anyway tccd wrks on low vdimm? lik tat i shd change my dt-d43 to tccd...
wat do u mean by vcore fluctuation on p4p800-x mobo? i c u mention a lot in ths thread...izit vcore voltage drop? or unstable vcore? i set my vcore 1.525 at bios...but whn open cpu-z it show 1.568/1.552....keep changing between both figure...y not stable at 1.525 like wat i set in bios?? 
does my vcore 1.568/1.552 consider vcore fluctuate oso? 
i dun thk so...i set my bios 1.525 but cpu-z shows 1.568/1.552..wic is higher thn bios....

hey guys if u all dont mind can give me a little guide to over clocking? i just bought my pentium D 805 2.66ghz. wonder if i can over clock it i'm using asus P5SD2-X

hey guys if u all dont mind can give me a little guide to over clocking? i just bought my pentium D 805 2.66ghz. wonder if i can over clock it i'm using asus P5SD2-X

the problem is i dono how to masuk my asus mobo's bios mode press F8 when loading?

and also.. before i over clock my PD 805. should i change the stock cooler? a better one something like TT big typhoon?

and also.. before i over clock my PD 805. should i change the stock cooler? a better one something like TT big typhoon?

yeah u should change for better cooling ...for me best air cooling is xp-120..but quite expensive la...for me performance is everything..

how much is that? i got a friend who recommended me xp something also

how much is that? i got a friend who recommended me xp something also

jz wanna knw hw u guys run prime test for HT proc?
im using 2.4c HT....i use sp2004....
izit open both sp2004 thn set one cpu 1 & one cpu 0 thn run both together??
or i shd set both cpu same 11 or 00??

COMPARESiON

b4 u change anything or do any oc stuff, y dun u glace through ur manual that comes wit d mobo and also understand every terms in bios

its sometimes not onli oc to get d best of ur proc... u can play wit other stuff such as interleave bank, raid setting..hdd prefetch..etc...

this will b enough for u to noe any temrs tat u wanna noe.. hope it help..
http://www.rojakpot.com/freebog.aspx
, u can run super pi/ pc mark/ 3d marks or any applocation for fast to noe it can survive or not b4 run prime test...

i think it is better to run one by one.. first, run small fft for 5-8hours (to test cpu)

then large fft to test its ram... and also run memtest..

coz so many thing to test, usually i test it after i happy wit d speed..

Hello to all sifu,

Need some advice here.Whats the diff between the new LGA 775 and the old?The old one using 800fsb and the new one 533fsb.Is there any major diff in performance?My last proc died was 2.8 800fsb now looking for replacement but the 800 ones are beyond my current budget.
Could u mind tell the diff between those two?TQ

new socket is 775..old socket is 478.....the difference is socket...
another thg is tat old 478 no more in production.....

what i meant was the old LGA 775 800fsb and the new LGA 775 533fsb?Any major diff besides the diff in FSB?Does that influence the performance and other difference between those two?Pro and cons?Thnx

theres no difference..the only difference is the fsb bandwidth..that all

800fsb is more superior with than 533fsb in bandwidth.The performance is also higher than the 533fsb which the proc only running with 133Mhz with quad pump.

This is another ramification of the limiting effect of the AMD dual-pumped FSB. A P4's quad pumped FSB (along with the superior optimization of the async modes) allows P4's to benefit in some cases from async modes that run the memory faster than the FSB. This is especially true of single channel P4 systems. There still are synchronization losses inherent in an async mode on any system, but the adequate FSB bandwidth of the P4 allows the additional memory bandwidth produced by async operation to overcome these losses and produce a net gain.
250MHz FSB speed with 80% or 5:4 (FSB:Memory ratio) results in 200MHz memory speed (DDR400)
This example is most often used in overclocking situations where the memory is not able to keep up with the speed of the FSB. On AMD platforms, there is really no point having a high FSB, if the memory can't keep up. When the memory or any other component is holding back system performance, this is called a "bottleneck". As in the example above, a memory bottleneck would be if you were running your memory at DDR400 MHz with a 500 MHz (250x2) system bus. The memory would only be providing 3.2GB/s of bandwidth while the bus would be theoretically capable of transmitting 4.0GB/s of bandwidth. A situation like this would not help overall system performance.

Think of it like this; let's say you had a highway going straight into a mall, with an identical highway going straight out of the mall. Both highways have the same number of lanes and initially they have the same 45mph speed limit. Now let's say that there's a great deal of traffic flowing in and out of the mall and in order to get more people in and out of the mall quicker, the department of transportation agrees to increase the speed limit of the highway going into the mall from 45mph to 70mph; the speed limit of the highway leaving the mall is still stuck at 45mph. While more people will be able to reach the mall quicker, there will still be a bottleneck in the parking area leaving the mall - since the increased numbers of people that are able to get to the mall still have to leave at the same rate. This is equivalent to increasing the FSB frequency but leaving the memory frequency/bandwidth unchanged or set to a slower speed. You're speeding up one part of the equation while leaving the other part untouched. Sometimes the fastest memory is not always afforded or available. In this case, more focus should be placed on balancing the FSB and memory frequencies while still keeping latencies as low as possible AND while still maintaining CPU clock speed (GHz) by increasing the multiplier. The benefit of a faster FSB (and higher bandwidth) will only become more and clearer as clock speeds (GHz) increase; the faster the CPU gets, the more it will depend on getting more data quicker. The only real benefit of async modes on AMD platforms is the fact that it comes in handy to overclockers for testing purposes; to determine their max FSB and to eliminate the memory as a possible cause for not being able to achieve a desired stable FSB speed. Even so, async modes on early nforce2 based motherboards caused many problems; problems as serious as bios corruption.

so what is the different between FSB 533mhz and FSB 800mhz peformance ? slow performance on gaming or office work? Anyone heard about P4 3.0 (524 model) LGA775 FSB 533mhz? I cannot find more infor about this processor.

errmmm... using 533 fsb got a lil setback... ur proc and ram wasnt running 1:1... so 800fsb is better as it runs at 1:1 at stock... running 1:1 imo is d best way...

yup... of course got slower performance if compare 533 and 800 as 800 is running 1:1... but not sure hoq much...

y u search for taht proc? go to intel website to search.. if still dun got, that means this proc never exsist in this world

It exsist in this world  Intel Website Just provide me less Information only , because this type of processor is always assembly by Dell or Acer brand dekstop pc. P4 3.0 (524) LGA775 FSB 533mhz . so i am confused with this processor specification.  Just know this processor at least have EMT64, but HT i am not so sure, but some chinese website, got mention it is support HT too. but i am not so sure.

IC7 or IS7 is a better mobo for oc?

Hello guys,im newbie,

Pls teach me how to OCing!

Dunno how to fill the form!

Intel PantaiTimun IV mPGA 478 2.8Ghz/133.3Mhz FSB/512K L2 Cache and my mobo:Asus P4V8-MX,Izzit good for overclocking?

Btw,do i need special fan for CPU and Chipset?Coolie Master 4 Lite can?

Pls help me,i dunno how to OCing,and what maximum Ghz for me?

THX!

For starters don't bother about cooling and stuffs. First you need to understand the concept of FSB and dividers. Make sure you lock the PCI/AGP bus for stability. Make sure you know CMOS reset button function/position in case of unbootable system.

Anyway check out the pinned fundamentals of overcloking thread. It consists of all information you need and more.

Same proc like mine.. motherboard almost same but mine is P4V8X-X ..
My pc sux to the max.. must underclock 10% also.. dunno wat is the problem.. 
Whenever i tried to run it at 2.80Ghz ( my proc speed ).. cannot get to the windows also..
