I can't seem to get a QX9770 to post on my GA-P35-DS3L. This is a rev 2.0 w/the latest firmware (F9).

I have an E8400 and E2140 which both post fine and can be overclocked (see attached images for E8400 overclock)

Here are the system specs
  • SeaSonic X750 Gold 750W 80PLUS
  • GA-P35-DS3L-rev-20
  • 8GB Corsair XMS2 6400
  • AMD RX580
  • 1x DVD+RW
  • 3x Western Digital Black 640GB
Any suggestions on which BIOS settings to change?

After you pop the QX9770 in your socket(after you make sure no pins are bent/broken) you might want to disconnect all power going to the board(after it's powered down) and remove the CMOS battery. Replace ti after 15 mins and see if you can boot with the QX9770. How are you working with 8GB's on that platform? Try with only one stick of ram.

Thanks for the info.

Using a single DIMM didn't work at first. I removed the CMOS battery for 15 minutes and kept only a single DIMM in. The system posted and the BIOS stayed open for a good 30 seconds before it restarted itself.

Unfortunately now it seems the system will be live for 30 seconds then reboot / power off. :(

Well the power supply shouldnt be a problem its got enough juice to power everythig. What cpu cooler are you using? E8400 and E2140 (65w TDP) coolers arent gonna suffice. QX9770 is a 135 W TDP and produces a lot more heat. Maybe the pc shut itself down becouse of overheating.
Also try to quickliy set bios to default settings before the pc shuts down.

I have a stock cooler for the E8400 and the E2140. For the QX9770 I have an old Cooler Master S2N-7DDLS-L6-GP (?).

I fiddled with voltages but now it won't even start. If I remove the 4-pin CPU power (and leave the mobo power) all the fans come on and DVD drive spins a bit. I suspect there may be bent pins on the CPU socket.

This has gone from bad to worse :(

Try:

VCORE 1.35V
VTT: 1.35V
Multiplier: 8
Bus Speed: 400
RAM Multiplier: Set to 1:1
RAM Speed: 400

You failed in RAM frequency. It's DDR, so it should say 400 MHz in BIOS so it would run at 800 MHz in OS.

After it boots reduce the voltages. These are max OC voltages bc your CPU is severely degraded after all these years of ridiculous voltage OC's and probs won't run at stock voltages.

Source: I used to own a QX 9650/ASUS P5Q Deluxe system from 2008 to 2013.

Thanks! As soon as I get the system booting again I'll try those settings.

FWIW I began experimenting with voltages to get the QX9770 to run; it hasn't always been that way ;)

Yeah, if you couldn't tell I've been riding this system for a while. E2140 > E8400 > QX9770. The E8400 has been in there about 9 years and pretty solid until now. I kinda wish I hadn't jumped on the QX9770 deal; live and learn.

About the cooler (Cooler Master S2N-7DDLS-L6-GP), if its like the one below (link) im quite sure its not gona cut it for QX9770.

Got the board booting but display isn't powering on. Possibly a bad PCI-e slot? I've tried
  • the CMOS trick again
  • memory reseating w/3 different sets of memory (Corsair, OCZ and BallstiX)
  • different power supply
  • repeated with the older CPUs
Probably time to hang it up.

Maybe the motherboard just can provide enough power to start the system with that cpu. Its quite old to tell the truth. Are there perhaps any "blown up" capacitors?

I don't see any blown capacitors.

Definitely old but tried and true for 10 years.

After reseating my video card it seems like the PCIe slot could be the culprit. Looking at high res image of "new" boards it seems awry.

Yep totally. I haven't paid much attention to the build community since 2010 or so. Changed to a dev / software focused role.

Anyway just purchased a new board and was impressed with 12 years of innovation. Small touches, innovations and lots of quirks fixed. Amazing!

Anyway, when I find a discount replacement Gigabyte board I will try to grab one. The E8400 is still alive and kicking as is the memory and 5870. I don't want to do a full Windows reinstall on that partition so I've put the components aside for now.

Thanks everyone for your help. I think we can considered this one closed for now.

Yes i belive you will find used MBs (lga 775) very cheap. I had not long ago had a secondary system (lga1155) asus p8z77-v lx which in all the years started giving me troubles with the first pci-e slot. I guess it bent somehow or somethig. Sometimes it worked and sometimes not. I simply installed my gpu in the secondary slot and it worked likea charm. Anyway good luck with all.
