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.

Yours is using INtel 865PERL mobo which doesb't have the o/c functions there.Regarding your RAM,since your processor is 2.4A which is not HT support + running in 533 FSB(quad-pump),so your RAM is resulting running in 166Mhz.

QUOTE(milky @ Jul 27 2006, 04:41 PM)

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

Your spec can o/c since using other type of mobo,not intel one.

i know intel mobo cant really unlock the multiplier.
so, should i inscreast the RAM speed to 266 or something?

can i use the easy tune to bump it up?

better bump it in bios..

@milky
u can use easy tune if u not familiar with ur bios.anyway it safer than use bios
but u get small oc result n stability.

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)...

The 4:5 means for 166FSB you set on the setting,quad 166 will the 668FSB on the CPU-Z. Where your memory you will get 208MHz from this equation (166*5/4).Get what i mean?

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!

Once you o/c even 1FSB,then is consider doing o/c already on cpu + RAM.If you wish to increase your FSB to 200 then you should try to o/c it to 200FSB then only know whether your system can support or not.No one can tell you the exact anwer here.This depends much on your system setup + hardware used.

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

Normally hte Intel doesn't support o/c but the new type mobo like the 975X does support o/cing.

kabukiawie

Sep 8 2006, 09:52 AM

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.

If you go to check the core 2 duo then you can see ppl using Intel 975X mobo to o/c. Well if can run on 1:1 at loose timing.Since Intel platform prefer loose timing than tight timing.

You can try on the PSB 533 strap setting with 4:3 divider. If you wish to use 1:1 divider...then you have to test out your mobo and RAM's maximum speed can go.

I try set to loose timing(3-4-4-8

loosest timing) and it run on 4:5, works fine but cant feel the different.

benchmark it is higher a bit. priming last night it seems no error after few hours. Will try to pump up clock speed to max, see how far it can go.

But when full load it drop to 1.3++v, like what you said, not stable. Mine i can be quite sure that is my PSU not enough juice

1:1 it should be ok for your proc & ram, unless you r using DDR333 ram. mine 1:1 can go till 180+ but not prime stable.

The best is using the 1:1 divider since both proc and RAM will be having the same bandwidth for data transfer.But the RAM's timing though playing a very important role on performance.

hows your Super PI 1M result? Mine only manage to get 44s

now you running at 180fsb@3240MHz, prime stable??

my crappy 2.4A limits me at 168fsb, even at fsb it give me error after prime for 5 hours.

i think thats the best it can go

not sure coz i jus prime around 6 hours only, will try to prime longer later.

But now got another problem, the voltage seems like not stable. The +12v jus around 11.75-11.95 only, never exceed than 12. I sense by using the MSI core center(a voltage n temp sensor s/w), it show me this result.

But when I c the voltage in bios, it is totally different(never less than 12v). Then, which 1 should I refer to? 11.75-11.95 volt will bring damage to my hardware?
