not the OS problem. i'm using xp 32 bit(sp2) also wif vista 32 bit(sp1), dual harddisk.i hv 4gb ram as well.can boot and run stable.just tht cannot detect full 4gb memory only although vista 32bit sp1 shows 4gb of ram in system information.

why this happen? any help?

i just know how to adjust fsb
i have tried it..sometimes ok, sometimes really hates me

another value do i must adjust to selain fsb??

help me plz

Yup, u're rite...Add the vcore until it stable to run n passes the benchmarking tools...

Hey overclockers

I hv a problem with my overclocking. Currently using P5Q dlx to overclock Q9550 to 3.5ghz. Using 4gb DDR2 1066 (Crucial ballistix)

Heres my setting :-

Vcore = 1.25v
Vtt    =  1.10v
Dram voltage = 2.1

Now, i stress it on prime95 n OCCT...it was stable but when i restart, the machine runs but no display and worst of all the lights on the RAM doesnt light anymore.

Please help thx

oohh..now my pc running at 350/1400 FSB..my ram are limiting me now, try boot at 400 FSB but it wont post..jelous saw those performance oc board can do high FSB..

does all x58 mobos have same DRAM frequencies or different mobos differ in frequencies? also, if i'm using a 1600mhz 8.8.8.24 ram can i go above that frequency?

Current rig:
Intel E8400 E0 stepping with Thermalright HR01-Never OC
Corsair 1066mhz 2GB X 2 with dominator- never OC
Gainward 4850GS -Official OC
Biostar Tpower I45
Mushkin 580AP

May I know how can I overclock this rig? I know nothing about OC and never try before. TQ

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...

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.

i'm already try what u said before..it give me BSOD...even i pump vcore 1.43v

"Need help. Try to OC my E8400 wolfdale EO to 3.6Ghz but failed. Failed to load windows.

Failed to load windows. First message was:

"The file is possibly corrupt. The file header checksum does not match the computed checksum"

Then I restart again, no more message. Problem to boot Win:

"Windows failed to start. A recent hardware or software change might be the cause.

If windows files have been damaged or configured incorrectly, startup repair can help diagnose and fix the problem. If power was interrupted during startup, choose start windows normally.

Launch startup repair (Recommended)
Start windows normally."

Try to launch startup repair but nothing happened(looks like it hang). Restart again and it hang."
CAN SOMEONE HELP ME PLEASE..........
