anyone knows this mobo can do overcloaking

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

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

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.

Actually i dun wan spend so much on PSU.. i tot that's the true power.. 300w.. it is listed there 300w PURE/TRUE power and 600w is the MAX power.. I got think of the ATRIX 500W pure power.. but then i heard someone said it's lousy also.. RM165 wor.. 

it's 12.03 ~ 12.09 .. between that.. is that stable ? 

hi all gurus...
hope to get some advice. thanks in advance.

here's some info of my P4 captured with CPU-Z, anything I can tweak to serve me better? smile.gif

CPU
[attachmentid=123215]

Mobo
[attachmentid=123216]

RAM
[attachmentid=123217]

SPD
[attachmentid=123218]

I think the RAM speed is a bit low.. isn't? please advice.

guys by looking @ my spec do u think can OC ?
default is 3.0ghz...

guys, can help somthg in this?



i jus wan to kno, can i oc my ram?
the divider is 4:5 (actually i'm not understand what does it mean...)

now i dunno my ram is 2.5-3-3-8 or 2.5-4-4-8.   i got 3 sticks of ram, 256+512+256, all are corsair.
since the FSB is 167, the divider is 4:5, then 167*(4/5)=133.6,  133.6*2(since it is DDR), equals to 267.2, is that mean i gona change my DRAM frequency to DDR266?

correct me if i'm wrong!(i know i must be wrong)...

Still the RAM QUestion here...
Please c here

1)From the pic above, my RAM frequency 208.8, times 2 is 417 which is closer to 400 coz my RAM is DDR400. So can it be say i OC on a correct way for my RAM?

2)If i keep on OC my proc and make the fsb to 200, then the RAM frequency ll becom 250, times 2 ll becom 500. Since my RAM just DDR400, so if I make to 500, my mobo can support it? Performences ll better or weaker?

3)Can I change the divider 4:5 to other?

Thanks!

I understand this 1.
But still on the question, can i change the divider?

my cpu is p4 2.67ghz....how much ghz is the best did i need to oc?

p4 2.67
1gb ddr2 ram
intel d945plrn mobo
ati x300 256mb
80gb pata hdd
dvd combo

But normaly intel board doesn't provide oc settings in the BIOS. If really cannot oc in bios, try clockgen....hehe just my 2 cents

@RokXIII
refer to your mobo menual, the setting for devider should be available. If you able to set it to 1:1, your proc can perform better than mine. C0 steping i think same as mine. hehe. i check tonight

Which is it better?

4:5 with 168fsb:208ram loose timing (i doubt my ram can run at this speed)
1:1 with 168fsb:168ram tight timing (currently running)

i will try play around tonight.
is it?  i didn't know that. I just know all type of mobo from Intel are not support oc.
@RokXIII
mine stepping same as yours, my max oc is up to 3.2+GHz but not stable.

you mean loose timing perform better for Intel? like 2.5-x-x-x?
