View Full Version : P35C-DSR3 Cycle Reboot Problem

09-24-2007, 11:00 PM

There seems to be an on going issue with the P35C-DSR3 board. People are now dubbing it the Cycle-Reboot problem. The problem is described as Power up, Fans on, Beep, Reboot in a continous loop never reaching the bios.

The problem does not seem to be localized to one part of the world either. I have read people in Austrailia, U.S., U.K., and Germany are having the same problem.

I have read about this problem on this forum - tweaktown.com as well as these forums


Does Gigabyte have a position on this? It seems like an ongoing problem that nobody has a solution for that ultimately leads to an RMA. Is it a bad batch of boards? Is it a bad bios? Something else? Is it fixable without a RMA?

I think the community would really like an explaination about the problem. Any info you can give would be greatly appreciated.

I'm experiencing this exact problem now and have posted about it at the e6750 / GA-p35c-dsr3 thread at the anandtech forums...and I'm about a day away from giving up on Gigabyte forever all-together because of this, it's been a hair pulling experience! I really wanted to love this board! Please give us a solution...and one that doesn't involve RMA'ing the board would be preferred! Can this issue be fixed by the user??

So that tells ya folks...

I ended up going with the Abit-IP35Pro Board, has a much better layout anyways and it's the only higher-end P35 board I've seen without the IDE connector stuck in a retarded spot...

Good luck if you go with P35c-Ds3r model! Sounds awesome on paper and the box is cool, but It's like rolling dice!

I was wondering if you received any info on this thread topic? I think alot of us are awaiting Gigabyte response on this.:beerchug:

I'm also having the same problem and love to hear if Gigabyte has a solution, or, even a clue as to what is going on. Just do a google search or read a few other forums and you will see this a common problem. My review is on Newegg and the reputation of gigabyte is going to take a hit if this problem is not addressed in some fashion.

Your first link does not work and your 2nd link doesn't work either. It keeps asking for "select product". Why can't you help us on this question? Why are you passing us off to this service? What do you engineers say?

I'm sorry but this seems like a bigger problem that needs to addressed. I hope you (Gigabyte) are not sweeping this under the rug!

Clearly this is a huge problem. Please address the issure for us.

Well mine's not boot cycling. But it is freezing. Up to 3 or 4 times a day. I emailed Janus for the version 3 bios and never got a reply.

A long time Asus buyer, this is my first and last Giga board.

Janus actually emailed me the F3 bios last night. He did say would should be using F4 though.

Well I'm curious if anyone who didn't overclock their board are experiencing cycle rebooting or other problems. In the other thread it talks about uncertaincy over the ram voltage. Wonder if its just the overclockers getting the boot.

I have this board and from stock [first boot] had this issue. If your using RAM with a higher rated voltage try setting this in the BIOS using some old DDR2 to boot. Once i had set the voltage to +0.3v i have had no problems since [yesterday....]. I think the default ram voltage is 1.8-1.9 and ive heard a lot of people say this is unstable.

I believe the default memory for this board is actually 2.0v. I have a trouble ticket with Gigabyte GTS right now. It's been going on for a week now. They have been giving me the run a round but I keep pushing :) I'll report back when they give me an answer.

Had a similar reboot problem with mine only each time it rebooted itd get a little further into the process, took about 5 minutes but it would eventualy boot up. Once it had booted it would start up again no worries until itd been left off for about 5 hours then the same reboot bull until it started again. Had it all checked out, perfectly stable when it was running, no fluctuations in voltages or anything just didnt like cold starts, had the tech guys buggered. Then 3 days ago the problem stopped the thing starts first go evry time now, i havent changed anything it just decided to work properly, has me a bit worried tho problems dont just fix themselves and i cant return the board while its working properly.

my system i just built using a gigabyte p35 dq6 - wont post anymore - i just installed vista, opened a browser window, and now i get the constant reboot. Tried 3 different bios's, and every conceivable memory voltage.

gigabyte needs to issue a massive recall, my board cost $250 and ive had nothing but headaches..

01-27-2008, 11:01 PM
same problem with X38 DQ6, I've mailed to GGTSE and after six mail I never just received a mail of solution or clarification, only great speeches without any technical information......
