guys,

I need ur help abit. Im running Prime95 on small FFT for 24hrs didnt come out any error but when running on large FFT, it comes out error. What opinions do u guys have abt this

This is my bios setup for Q9550 E0 OC 4.0ghz on P5Q DLX

FSB - 475
Vcore - 1.46825
VTT    - 1.3
PLL    - Auto
NB and SB - Auto

Help me out thx alot.

large fft usually refers to ram ehh... wats ur ram settings?

u shud try blend test.. it maybe caused by faulty ram or instability of ur oc..

guys..i need your help here..i'm just want to try intel power...

i got cheapo proc to learn oc...before this i'm AMD user

why i using ORTHOS then after 2 minutes got some error..did my ram cant go high or need to up more voltage...

my spec...

E2140
DFI Lanpaty UT P35-T2R
Corsair DHX 4gb PC6400 kit

takkan moderator noob oc....

btw those DHX is rated at 2.1v rite so why dont u run it with the rated voltage and try again.

hello lowyat forumer and sifu, uber clocker....i have no knowledge bout high-end overclocking....but i just have only know OC cpu but don't know OC to high end like 4ghz or something like that,and i have google till my eye out....i tired that most the google i search is they show how to understand....the only thing is....i sux at math ...so i don't know the exact,truly OC'ers like other professional did....and those are my spec and i hope some ppl help me here....not i lazy or seldom...but it is dumb enough to understand while i really don't know the setting of mobo,only need what the setting is....

intel C2Q E8200 2.66(6mb cache,1333FSB)

edited cpu

Yup,try to add in some vdimm,cause i know DFI has vdrop over vdimm area.

any software to test the pc full performance after OC? temperature gauge meter software also?

already found Prime95,is it ok?

Test 1
Vcore: Max
VTT: Med
GTL: Light
NorthBridge: Low
RAM: Low

Start SP2004 Orthos
Set Test option to 'Blend - stress CPU and RAM'
Still under Test option, Click 'Custom...'
Under Custom Test, change 'Min FFT size' to 8, 'Max FFT size' to 8
Under Priority Option, change to 10
Run SP2004 Orthos

Make sure SP2004 Orthos is kept running and passed approximately 35 minutes.
In order to achieve that, you need to run two rounds of 15 mins SP2004 Orthos. After that run Test 2 to make sure it can start the third iteration of 4096 and the quit.

Note: You need to keep increasing your vcore until you did not see see any difference or to pass this test.

Test 2
FSB: Max
RAM: Med
NorthBridge: Med
Vcore: Low
GTL: Low

Start SP2004 Orthos
Set Test option to 'Blend - stress CPU and RAM'
Still under Test option, Click 'Custom...'
Under Custom Test, change 'Min FFT size' to 4096, 'Max FFT size' to 4096
Under Priority Option, change to 10
Run SP2004 Orthos

Same as above, you need to pass approximately 33 minutes with two rounds of 15 minutes. After that run Test 2 to make sure it can start the third iteration of 4096 and the quit.

Note: You need to keep increasing your Northbridge and FSB Termination voltages until until you did not see see any difference or to pass this test. FSB Termination voltage is to be maintain 1 level above NorthBridge voltage, especially for Intel P45 Chipset Mainboard.

Test 3
GTL: Max
FSB: Max
PLL: Max
Others: Med

Start SP2004 Orthos
Set Test option to 'Blend - stress CPU and RAM'
Still under Test option, Click 'Custom...'
Under Custom Test, change 'Time to run each FFT size (in minutes)' to 1
Under Priority Option, change to 10
Run SP2004 Orthos

Make sure to pass all the SP2004 Orthos FFT tests which is from 8 to 4096. After that run Test 2 to make sure it can start the thrid iteration of 4096 and the quit.

Note: You need to keep increasing your GLT and FSB Termination voltage until you did not see see any difference or to pass this test.

Test 4
NorthBridge: Super Max
Ram: Super Max
Others: Low

Run Memtest for Windows
If you are running 4Gb of Memory, run 2 instances of memtest each at 1700. Make sure you passed 100%.

Note: You need to keep increasing your Vdimm voltage and tweak your Northbridge settings until you did not see see any difference or to pass this test. Through Northbridge tweaking, you will know when there is affect to vdimm increase. For example, you keep on getting an error at a certain level.
