Cleared CMOS, tried swapping RAM...still no POST! Help?

post #1 of 11
Thread Starter 
So, I was having some luck overclocking my new system here. I started by setting everything up in the BIOS according to a guide by Tony at The Tech Repository http://www.thetechrepository.com/showthread.php?t=41

I set memory timing to what my stock settings are 4-4-4-12.
Vcore was at 1.30

When I adjusted CPU frequency (FSB), the DRAM frequency would adjust accordingly.

I managed to get to 2.6ghz without a hitch, just by turning up the FSB. However, I got to a point where it wouldn't boot, or it double booted and then gave me the "windows did not start correctly" start in safe mode....

So, the DRAM frequency was in the 800mhz field, the third from the top when you're at the AI tuning menu. As you change the CPU frequency (FSB), the DRAM changes accordingly. I had a 1:1 ratio going.

So as I increaed the FSB, the RAM was going up above 800mhz. So I lowered it to whatever the first field was. It normally starts out at 533 mhz, but I pumped up the FSB until it made that first field go all the way up to 800mhz.

I boot up, windows loads! Hooray

I'm looking at a 3.2ghz E6400. I don't remember the FSB, but perhaps someone could figure that out based on the 3.2ghz and 800mhz memory. CPUZ says the memory is at 400mhz, which I remember is DDR so, it matches the 800mhz I set in the BIOS. I really hope this is correct and not 800mhz X 2...which I think the memory would fry...I dunno.

I load up two instances of Prime95, attempt to test out this OC. I see CPU temps go to 56...15 seconds later the system shuts down completely. Yikes! Usually it just freezes.

I didn't have time to mess around so I left it overnight after unplugging.

I checked all connections, I swapped out the RAM and tried all different combinations. I reset the CMOS a few times, in any method I've heard of (pressing the power button, waiting 10 minutes).

The system completely powers up, fans, motherboard LED, PSU, GPU, everything, except I get no beeps, no POST, no nothing! It powers up, then does a double boot thing, then stays powered, just no POST...

What else can I do? I had 3.2ghz CPU speed with 1:1 ratio with my memory. What FSB was that? Was that complete overkill? Did I fry my NB? HELP! No burnt smells, but I should be OK as I was monitoring Vcore and was at 1.3V

Maybe someone can help me out here?
I know there's a trick where you boot with no CPU installed. I think I need a break and will grab something to eat before I go pulling CPU's...

I REALLY would appreciate any input on this. I've reset CMOS's before, but this is killin me as its my first complete custom build and my first attempt at overclocking the CPU I can't post after CMOS reset....

I had that problem when i went overboard. I usually completly took off the power from the power supply and tried booting with no success. It took about 3 tries and the system would post and say CPU error and it would load all the defualts back in the bios. Give it a try.

Yea try that...unplug the PSU, and take out the watch battery on the mobo. Wait a few seconds, and then put the battery back in and boot up.

I don't mean to be rude but do you have any reading comprehension skills at all?

I said I cleared the CMOS in the subject, and then I said I tried it several times within the post.

From what I read from the other post, is that I'm supposed to try and press the power button while there's no power connected. Which I already did.

I've eaten and rested a few hours, shall I try the no CPU trick?

Is this with the battery out and jumper set?

Or just default jumper and battery in place?

I think you miss understood. It might not work for you. All i did was unplug the power from the power supply and then waited about 1 minute and tried it and it wouldnt post. I repeated this about 4 times and then it came up with the error and reset everything to default. I did not take out the cmos battery.

OK. Maybe I will try waiting longer than 1 minute.

I'm about to try and power up with no CPU, and see what happens...

EDIT: Still nothing. Powers up for a few seconds, no beep. Then powers down. Then it powers BACK on by itself, and hangs. No POST, no beep, no BIOS, no nothing. Everything is lit up and fans are whirring away....

this sucks.

Try doing this, unplug the power from the mobo and take out the memory. Wait about 30 minutes just to make sure. Then plug everything back in.

Some ASUS MBs can be odd with clearing the CMOS.
1. Unplug PS
2. Remove battery
3. Toggle the PS on/off switch several times.
4. set jumper
5. wait 10 seconds
6. If that fails repeat 1-4 and wait 10-30min. I've had a Asus that was odd and took an overnight wait to clear it

Thanks. Someone also suggested putting the battery in backwards, setting the jumper, then putting it back. I never heard of that. I'll try these last couple of things. While I'm waiting, I think I'll try out this PSU on my old willamette system.
