N680SLI-DQ6 NICs problem

[Wolfclaw]

Purchased as a factory reworked and having major problems with all of the nics dropping connection after an hour or so.

Running latest Win7x64 drivers, latest BIOS, tried various combinations of settings in device manager TNA, even purchased new 500w psu.

Anybody shed any light?

Sounds like a component overheating somewhere. If they work for a while and then fall over it is normally down to heat.I would say take out a ticket with GGTS and see what they say but it sounds like a motherboard fault.

[Wolfclaw]

Thanks for replying.

Thought about that, but it shouldn't be an issues, as I have..

1 x 120mm intake
1 x 120mm exhaust directly behind Freezer 7 Pro on CPU
2 x 120mm intake blowing onto motherboard

North/South bridge heatsinks warm to touch.

Your case may be at a low enough temperature but that doesn't mean that some component on the motherboard or elswhere isn't getting too hot. Maybe through a fault.

[Wolfclaw]

OK, thanks have logged with support.

Well after attaching a small heatsink to southbridge, helped to reduce temps, the board has finally given up and now fails to post.

Any idea how long it take GB to send an acknowledge email for ticket?

How do I stand for a repair under warranty with this being a "reworked" board?

[Dark Mantis]

Generally GGTS takes around a week to answer the questions. I am not sure on how you stand regarding the reworked board. Was it a factory rework? If so then I guess that you would have a good chance of claiming the warranty.

[Wolfclaw]

Supposedly a factory reworked, box still has old RMA number on it.

I have managed to get the thing working again, it bounced around trying to do a auto bios recovery a few times.

So replaced cmos battery to be on the safe side, now can only read gpu and boot hdd info using CPUID hardwrae monitor and if I power off or do a restart, system fails to boot. Have to switch it on an doff a few times before it kicks in.

Daft thing is, when its up, its running better now than before, computers, don't you just freekin love em.

Can you post a list of your hardware including PSU please?

Quiet! I wouldn't go shouting about it someone might hear Besides someone has to do it.
To be honest I really didn't think you were a noob from your specs. I thought maybe the problem was power supply but even though you don't have a lot of headroom I wouldn't think that you are over your limit. There is nothing there in your list that stands out as problematic.
The BIOS doesn't leave you with any options update wise. You haven't listed the actual model of the memory so I couldn't check that it was compatible but that might be worth doing.

Should be OK, they only warn about populating all 4 dimms on a 680i / 650i.

[Dark Mantis]

Assuming the memory is ok then I would say you will have to RMA the board. Might be worth just running Memtest86+ on the modules first though.

[Wolfclaw]

Done that 100% OK, also plugged them into my sons Asus PK5 + Q6600 and no issues.

Don't think I can do any more, so awaiting reply from support.

[Dark Mantis]

No to be fair it was only a long shot but worth a try. The fact that they worked in another board doesn't of course prove compatibility. Can't think of anything else to try so as you say will have to wait for RMA. Hopefully not too long.   Please come back and let us know how you get on though.
