@sang_karim
you easy la, drive car can reach lowyat liao la. me, edministrator, fylon have to book airasia and taxi to get there le.

@fylon
understand your feeling now. for us that staying "oversea" have to wait and wait for rare item to come. really wish that lowyat is at kch, then we senang2 lepak there windows shopping. hahaha....

Yalo.. Always need to find alternative way! Haiz... We need airasia to get there! Duh.. Guess just grab that 450W will do already la.. 80% max efficiency should be alright..

more than enough la...

@kabukiawie, i might drop by KL in october for work... if u need anything, well.. ..hehehe...

Yea.. Just grab that 450W ok liao lo.. Bopien.. Hahah! well.. U going to KL edmin? Grab me some casing! Jk..

450W real power with front panel meter is sweet under RM300. casing? can, 20% service charge, lol, jk jk. I will try survey for Encloxure casing when i'm there.

Yea.. The one with blue fan and power usage meter. RM245/250 lidat. Dont the AVF got raise the price or not due that day i ask is old stock. Interested? Nah.. Jk la.. Anyways, planning to get CM Centurion 5. The one with all black edi. Hehe.. Here got! No worries!

guys..some update ... here my cpu oc result ... i still don't run stability test yet ... maybe my cpu hit the wall oredi ...

FSB = 250MHz ... running at 3.75GHz and Vcore set to 1.45V ... don't dare to up the vcore anymore ...


Here the 1M superpi result ...


after this i should test for ram oc according to guide given by overclockalbert ... or should run stability test first ti find the stability setting for cpu oc?

Wow.. Ur firing ur rigs up man! Good result.. 3.75Ghz.. Good result! But ur rams speed seems kinda crappy. Try change ur ratio to 3:2? Running on 5:4 were giving low bandwidth thou. Haha.. Can hit that speed with 1.45v core sounds not bad. Mine last night need to up until 1.535v then mange to maintain the stability.

I always prefer to run on run speed, 1:1 ratio! But its hard to achieved due need to push the ram speed same as the procs.. As for me, i will always run stability test 1st. Cos if ur system can pass the stability test means its stable at that speed, thus no worry that u cannot get that speed.

By then, what program are u using for test out the stability sang? For me, i used to use Orthos! Its will automatically detect how many thread and ur proc has and prime both of them at the same time. And also, if can, do ur priming at priority 10. To fully test out the system. Give 100% burn in.

i only have sp2004 ... will it be ok? do i have to open 2xsp2004 or just one only?? err...how bout the ram oc? have to do it first or just try with 3:2 ratio??

Lol.. Google for Orthos that will be more better then SP2004 IMO.. Hm.. Its dpend on u. U might try change the ratio to 3:2 1st and see the sytem is boot able or not. If bootable then get into windows and run priming program.

By then, what is u idle and full load temp for 3.75Ghz?

@sang_karim
you are the man!! not bad!! very sweet oc. can up somemore?? i think it shouldnt be any big problem rise the vcore tll 1.475v. can squeeze a bit more. coool another new comer come challenge fylon to beat shawty's 4ghz. XD

use orthos for stability test.

Hi guys,i'm ok with my grandma passed away. Thanks for your concern. Anyway,i'm now using my new HDD man. So nice,just setup the things only.Busy to install softwares now.Er..the 76GT plan to get but not now...hehe.

@sang_karim,

nice result for the OC. 3.75GHz


To test the stability of overclocked CPU: using prime95 stress program :

Double click on PRIME95.EXE to start the program.

Just Stress Testing (if prompted) > OK >
Options > Torture Test > Blend


The program should not give any errors.
It may be necessery to run the program 12 hours to make sure an overclocked system is stable (no program errors displayed).


If you get errors only after several hours, this is a result of slight instability because the system is running with little or no margin. It's stable enough to boot and to be moderately stressed, but as soon as the system is under enough load to go over that critical point, it will freeze. To be 100% stable, Prime95 should run 12-24 hours without any errors.

The whole point of testing is to see if you get errors or not thus testing the stability. The meaning of errors themselves is not the issue.

And here for u to run the dual instant of Prime95 :


Running a hyperthreaded CPU and wants to load it 100% instead of just 50%.

Here:

-Open the Prime console as you normally would, but don't start the torture test.

-Then go to Start button - Run.

-Click the browse button and find where you located Prime95.exe Once you find it, click Open.

- The path in the browse box will probably look like this "C:\Program Files\Prime95\Prime95.exe"

- Put your cursor at the end of that text line after the ...exe"

- Press the space key once and then type -A1 (dash A one)
"C:\Program Files\Prime95\Prime95.exe" -A1

- Press the OK button.

You now have two Prime Consoles

Now before you begin the tourture test, go to Options - CPU and in the two boxes for amount of memory used, take whatever number shows in there now and divide it in half, and then enter the new halved number in both boxes. Save and exit the options box. Do the same thing for the other Prime console. Failing to do this will result in the chewing up of your paging file (I know cuz I just tried LOL )

Now run Torutre Test on both consoles.....

You're now using 100% CPU Utilization on an HT CPU.

**All this from XS forums.


for your system, why i saw u just running on single channel? had u install the ram in the correct way? try to install
them in the ram slot which have the same colour.

as for the FSB:Dram ratio setting, u might stick with 5:4 ratio.


FSB : Dram
5 : 4
250 : 200

if

FSB : Dram
3 : 2
250 : 166


you will have more crapy bandwidth on your system. Actually higher bandwidth is better for your
P4 system. just try to stick at 5:4 and try to tighten your rams timing as your ram is running at default
frequency now @DDR400 so u can set the timing to 3-3-3-8 ( is this the default timing for yr KVR ram??)

as for the Vcore , what is your default Vcore as intel recomended???
as in the CPU_Z screeny, i saw u have a pretty good temp, 40C. just try to run prime95 to see weather your system really stable.
u need time to tweak more on the Vcore and timing (IIRC)...i was once a P4 HT fanboys......


happy OC-ing......

xD... Im out dude. Let sang carry the mission forward. Yea.. He did a good job thou. Can hit that speed, might becos he was running on 3:2 thats why can push higher. As for me, i used to aim for PERFECT. 1:1 ratio, tightest timing with the fastest speed! Thats what im request from my rigs!

By then, 1.5v will be the max vcore for Prescott core. Dont over that line..

oredi download orthos and try running it at 250FSB but windows kindda stuck within1 minute .. then lower the fsb to 249 and still the same .. lastly set it at 245FSB and running it till 22 minutes with no problem ... stop it to post it here... .. full load temp bout 49C and idle around 38-39C .. seems ok to me ... will try the 3:2 ratio later ...

@kabukiawie
1.475 still ok aaa? hehe ... will try it later la bro .. wanna try that 3:2 divider first ...

not that early to give up la, fylon. you still have the power to fight.

nice guide, overclockalbert. sang_karim has a good hfs there. cooling shouldnt be a big problem for him

@raymond
ust grap a 76gt drr3. sure rock. XD you there easy to get 76GT agp??

@sang_karim,

try to post some of your dual instant prime95 screenshot to gather
with CPU_Z screeny for us.

now u are setting 1.45V for Vcore right?
and fsb to 245Mhz so u r running 245X4 =980Mhz not bad.

as for the temp, 49C under full load....... are u using water cooling setup? or u r in AirCond room?
that was a really nice temp that a prescott can do. mind to tell your cooling method?

From lyp list there i got see 76GT.A few shops are selling them actually.

Field Value
Sensor Properties
Sensor Type ITE IT8705F (ISA 290h)

+3.3 V 3.42 V
+5 V 5.00 V
+12 V 8.19 V
+5 V Standby 5.00 V
VBAT Battery 3.06 V

I found out that my +12V line voltage is way too low I've changed my psu and it only increase the voltage by 1V
Resetting the BIOS doesn't help Is that means my mobo die edi?

DO u have DMM? try to measure it out at the molex connector. yelloe to + ve and black to -ve end.
if the voltage from DMM is 12V, then something must be wrong with yr sensor chip or the mobo bios errror.

go check the actual 12V with DMM 1st, then u know.
