Failures at booting, CPU problems.

[Niels Rikhof]

I recently installed a new CPU in my pc (intel 2 quad q9400 )

Asus p5b motherboard
intel core 2 quad q9400 2.66ghz
2gig ram.
nvidia 9800GT

Before I installed the CPU i flashed the bios (too 2104) because the bios version was not supporting it yet, it all went great.

Except for the booting part.

First it wouldnt boot at all (well, the fans went on etc but no POST beeps and screen), turned of the pc again, removed the power cable for about 20 secs, turned it on again and i heard the POST message, it was normal. After the ASUS screen i heard another beep and the following screen popped up

"Overclocking failed" Press F1 to enter setup or F2 to load up defaults (second hand cpu, looked in the bios and its running on 2133mhz...so its a downclock?xD)

By pressing F2 my computer will start normally. But the CPU runs idle at 1600Mhz ( i read something about speedstep ), but in stressed mode only at 2133mhz... Bus speed at 266mhz (wich is not right ??)

Well here's a pic.

Funny thing is, i cant change anything in the bios because when i change settings and i save and exit, my computer will not boot up and it will automatically reset the bios settings anyway otherwise i wont get past the "overclocking failed" screen.

I also removed the CMOS battery a few times (even bought a new one).

Any help, guys?
(I am not a grandmaster in English, and ofcourse pc's).

What happens when you set everything manually and the FSB to 266. Does it boot?

Leave the settings as they are and try increasing FSB gradually, keep the memory divider at 1:1 (minimal). Start from 266 and increase it in steps of 10. See where this will take you. If it is possible, determine the maximum FSB frequency your pc will boot with.

By setting it on 266 it will boot. Gonna try higher now.😀

Came to 315fsb now its stuck here all the time when i want to enter the bios or boot the pc. I guess its getting to hot??. In approx 1 hour i can get a artic freezer pro cpu cooler . Im using atm one from my old cpu (e2180).

I'm going to call it day.
Some final thoughts for today:
If you get stuck like now, you need to do a BIOS reset via battery removal or jumper shorting.
Start taking notes on paper which settings work, so you can get right back to them after hard reset.
Boot at 266MHz with CPU Vcore set to 1.2125. Use CPU-Z to verify actual difference between what is set in BIOS and what actual voltage is. Adjust it as necessary in BIOS.
Use coretemp to check temps. Your old cooler is not enough
Play with all the settings. Maybe raise a little NB and ICH chipset voltages.
It looks like 333MHz is a bit too much for your mainboard.

Something to try after everything else fails:
This may be a FSB gap. You may want to try something like 380 x 7, but this will overclock your memory beyond 667MHz (to 740) so bump memory voltage and loosen the timings.

I'll check this thread in the morning.

Will do my best. Thanks for all of your effort

edit:

Got it running on 2.63ghz now (idle around 1.98ghz, c1e is still enabled)
And with the new cooler it's idle around 35 degrees.

Also, i got myself 2 other memory sticks, 2 corsairs 1024mb 1066mhz.

FSB speed in bios is now @ 330/329 , havent put it on max with the new memory, and im too tired to look at it now (i prolly have them running at a odd mhz). Will see your reply tomorrow 😀

Is it stable? Have you tested it with prime95 or something similar? I'm not worried about CPU, rather about the platform as a whole.
What it took to get it to 330MHz? What settings did you change?

Are these sticks the Corsair Dominators?
You motherboard supports following memory dividers: 1/1, 4/5, 2/3, 3/5, 1/2.
You can run you memory on 3/5 or 2/3. This would give:
330 / 3 * 5 = 550MHz * 2 = 1100MHz (slight overclock)
330 / 2 * 3 = 495MHz * 2 = 990MHz (underclocked)
I would go for 1100MHz at settings from EPP1 (5-5-5-15 2T @ 2.1V). This modules should handle that easily.

With this memory you can try 7 x 380 FSB, but this will force you to disable the c1e. Additional 30MHz is probably not worth the hassle. I'm simply curious if 333MHz is in the FSB gap or your motherboard is already at its limit.

I cant tell you atm it wont boot. I dont know whats wrong ;/. Had the pc running 10 hours but had not rebooted it untill now. It was stable but i dont know in stressed mode. Im on mobile phone now but have to search the booting problem now 😛 .

They are dominators but they came out of a damaged pc (water). Did not recieve any error during the night/morning. I guess its now the booting prob.

 

[Niels Rikhof]

Alright. Didnt know what was wrong but after a cmos reset it booted again and I put in your settings. Couldnt choose 1100mhz for the ram but could choose 1111mhz so picked that one. Gonna do a stresstest now to see if it malfunctions. (@333fsb now)

1111MHz for RAM is correct for 333MHz FSB. When you increase FSB its frequency will also increase.
Memory is running now at 555MHz, this is overclock of 22MHz, so this modules should be capable of running at this speed no problem. You can test it for errors later with memtest86+.

Now, you got to 333MHz FSB and are running your CPU at its stock level. What is left to do is to test the stability and fine tune settings. Looks like the mission will be shortly accomplished.

It ran stable, kept prime95 running for a few hours. But after a reboot it won't boot xD. Except when i unplug the power, go in the bios (where the settings are still the same), load the same settings and it boots again. Now this isn't a real problem to be honest, but its not 100% xd.

I can even run it on 2.8ghz withouth any hassle or bluescreens/any other errors.
