or can try papst or panaflo.
using 3 tonados,trust me, u need a fan controller!

Guys please help me newbie. Thanks

227x15=3.4 (2.5-3-2-7)2.7V
3Dmark03 -- ok
Aquamark -- ok
3Dmark01 -- ok
Super pi -- ok
sisoft -- ok

But when trying 230x15 cannot lioa. An error on 03 (stuck at orc)and 01. Others dint try.
Icute450W,P4 3.0C, MSI 875PNeo, Corsair CMX512x1 Pro

When try 234x15 in windows lauching 3D03 system proof error shutdown.

splinter, try raise 0.25vcore and try again.

b4 that, dump the icute PSU for a better one

0.25Vcore. IC, but i think i try it on new PSU. +0.25 = dangerous or still safe to play with? SOrry dunno much about OC. Normally its hard to OC higher with the stock Vcore right?

not really.
it depend on your CPU.

eg. some 2.4c can oc to 3.3ghz easily with default vcore
some 2.8c can do 3.8ghz easily with default vcore

heard 3.0c isn't that really a good overclocking chip...

yeahh. mine dead less than 2minute after hitting the 250FSB barrier
last time using MSi Neo2-V i865PE. all setting for both cpu & RAm r default wan
1st its fail to boot & hang at start-up screen, after clearing the BIOS, both mobo & cpu damage edi

Stock Vcore bios = 1.525 and Corecenter show 1.55

OIC, then i better stick with 3.4 better. since it pass all test. Not prime yet. Maybe wait i get a new PSU 1st and more ram 1st. No point, last time when bought it dunno... or else i also go for 2.8C since its cheaper and good OC. Hai~~~

Max temp 53C ok? reading by corecenter.Speedfan is 52-51. And also about PCI/AGP lock. when increasing FSB, it automatically increase too till 77+ then i manually set to 67.01/33.50. Is it ok for current Ati9600pro and future upgrade (6800 or wadever)?

hi to all sifus...need help on overclocking my system

1) p4 3.0GHz presscott:
i was able to o/c my cpu to 3.75GHz with fsb set at 250MHz. the question is how much is the Vcore threshold for this cpu? default should be 1.375v now o/v to 1.4125v is it still in the safe region?just dun want to burn my cpu....my current temp is around 53~55c max...is it fine?

2) Corsair pc3200 xms twinx ver1.2 (ch-5?)default timing is 2,3,3,6
my mobo is asus p4p800se, the max o/v i could do is just 2.85v and the result is 2,2,3,5@200Mhz but if o/c the fastest speed ascertain is 2.5,4,4,8@225Mhz, which one is better? also anyway i can go higher on the voltage for the vdimm? any alternative rather than using the ocz booster?

eh... i got a question.... when i run cpu-z, the voltage of my pc is not stable..i mean the value keep on changing... is that normal???

No sifu here, but trying to help...

1) besides ur overclocking results what interest me is the temp...53-55c max???if i were u i kick in more vcore coz ur presscot is consider a cool one...mine at the office running 67-75c stock vcore....

2) i havent heard any bioses that has the option but u can try to get booster and find out if u can pump in more juice...since it is safer that vmod...its better too...


flunctuations is normal.... -+0.03 but if the flunctuations is more than -+ 0.05/6 thats abnormal....PSU problem is most common,...dirty current should also be the problem...

ic.... is vcore affecting the flunctuations

it is the motherboard itself.

as long as the flunctuations keep at a very small range, it should be safe.

Cant get 3.0C ->3.4. At 3.4 everything is ok,3Dmark01,03,Aquamark,sisoft,super pi.The only that cant pass is Prime95 1 errors. Really bad.

Guys google around found that if stuck certain stage, can try playing divider. How to play on my spec?

[/quote]so what is the max voltage this cpu can take?

2) i havent heard any bioses that has the option but u can try to get booster and find out if u can pump in more juice...since it is safer that vmod...its better too...
[/quote]any info how to use this booster? thanks so much for the helps....

this is the highers clock possible on my intel destop board D915GAV....i think i need buy another board tu overclock my pentium(ES)..huhuhu

here also i attach my cpu-z info...take a look.


Attached thumbnail(s)

i915 chipset = locks upto 10% of the standard FSB, after that it wont boot.. ada safety mechanism..
if you still wanna playaround with your current mobo, you can try adjusting its chipset voltage (if you have that option la.. will increase 10 - 15 MHz jer, but better than nothing) ..

btw, where did you get your ES from? and how much?

hmm....actually i get it from my brother...he work as intel engineer at intel penang...ES very rare right?...that's why i use dekstop board D915GAV...the standart intel mobo..he gave all that to me as my birthday present...i'm still newbies in overclocking....so i keep on discover it.

nizamextreme, if u want to oc more.
sell the board and get a nice i865pe or i875 board.

Hehehehe...actually we're planning on getting the Lanprty UT 915 T2 as he's quite gatal about the Winbond OC thingy edi and he still wants to play with DDR's. And the BIOS is quite funny. No voltage adjustments. Just timings and a fixed set of FSB's from 333/400/533/600 which I presume are more to dividers. And since it's an ES, can play with multi's too
