So as the title says, I can't get this new system to post. Any ideas? I've double checked that the cpu is placed correctly.

Everything is connected, including the ATX CPU 12V connector? Does it beep?

Reply to GhislainG

Yes, the ATX 12V power is connected. I've even double-checked that it's working with my multimeter. It's stable with 12.02V on both pairs of leads.

I've since tried another power supply as well that is known to work. I've also tried clearing the CMOS by shorting the appropriate header.

The darn thing just sits there with the fans spinning away, but not beeping at me, even if I pull the RAM. Grrr....

Is there a piezo on that motherboard or did you connect a speaker? Just to make sure that it isn't shorting out to the case, remove the motherboard and put it on a non-conductive surface. If it still doesn't beep, then either the motherboard or the CPU could be defective.

Thanks for the suggestions. I had the PC speaker connected. Not sure if there is a piezo or not. I'm actually trying it outside the case right now. No luck unfortunately.

Looks like I'm RMAing the mobo tomorrow :(

I just checked the picture on Gigabyte's site and there is no piezo. That's why you need to connect a speaker to the speaker header.

Eeek - I hate to be the one pointing this out, and it may be nothing, or I might just be blinder than usual, but

the GB CPU list for that board doesn't seem to list the 5050 - it does list some other brisbane-based G2 45W models, but not that one, that I can find... Might be worth a question to janus Yeh (GB support guy at TweakTown:

Thanks bilbat,

I noticed that too. Strangely, it _does_ show up if you view source for that page (I notice because it showed up in Google results, but not when reading the page). I also found a forum post by someone successfully using the same mobo/CPU combo.

Confusing. I guess you're right about checking with GB support.

TweakTown is a pretty stout GB forum; even if Janus doesn't get right back, someone will know something...

Yea gods - now I've gotta start reading the source at GigaByte?!? :pt1cable:
They're just gonna have to move their ^&%$ web-site offa that old Apple IIe w/16k of RAM - today I dl'd a manual to answer something and got an 8k/s dl speed - figured the model'd be obsolete before I could read the manual...

Well, I noticed in the HTML source it is listed as "in testing". If I'd realised it was only released by AMD last quarter I would have checked before buying it. Doh! Well, if it's not supported yet, I hope a BIOS update will fix my problem. Of course, I'll have to get the cheapest supported processor I can find to update the BIOS first.

Thanks again for all the help everyone.

That works - I have a DS5 that was intended for a 9550 E0, but the BIOS shipped didn't support it - no one @GB was willing to say either it would or wouldn't work just to flash the BIOS, so now I keep a cheap E1400 in the box, just to pop in for the ten minutes it takes to flash - low cost insurance against bricking a board...

Any luck getting your mobo to post? I am having the same issue with mine, not sure if its the PSU or not.
Same MOBO w/ x2 6400 athlon, 450W raidmax PSU
