Potential 680i issues

Hi all...I have been having some strange issues for the past few months with the system in my sig. It started with the system hanging on post code 75 (HDD detection) and eventually booting after a good amount of time. It would then refuse to boot into windows (vista 64). To make a long story short I ended up replacing my RaptorX with a new Seagate drive. I reinstalled Vista on it and the system seemed fine for about a month or two. Now it will randomly freeze while playing WoW and will then "resync" after anywhere from a few seconds to one minute. It has done this very frequently, sometimes several times per minute (and it does it outside of WoW as well. i.e. when using IE). Other times it will just completely freeze and the ram activity LEDs will show little to no activity. Upon a hard reboot it will usually (but not always :rolleyes:) hang on the 75 post code. Then after it hangs for a substantial period of time it will either freeze on the Windows load bar or take forever and a day to load into Windows. If it loads Windows after this behavior it is terribly slow. It also will hang on shutdown or will not come out of sleep mode. Then there are days when it acts normal and can handle whatever I throw at it...though the former has pretty much been the norm for the past week.

I have run memtest, checked all cables, changed memory banks, tested the video cards (just to rule everything out)...I'm at a loss.. Oh and it never gives a BSOD (and I do have that turned on)-just freezes. Temps seem normal.

I am about ready to chalk this up to the legendary issues with 680i boards, but wanted to see if anyone had some ideas I could check out before I look into buying a new board. Thanks :)
 
just buy a new board :-p it sounds like you checked everything. you could try to do another reformat to ensure its not the OS. I have a lot of problems with my board as well. Good luck
 
Check your MCP temperatures in the BIOS when the system first starts up. Give it about five minutes if you are doing this from a cold boot after the system has been off for a few hours or more. If the temperature reading is in excess of 50c idle then the board is probably in need of replacement. I've personally documented this issue in 5 cases regarding the 680i SLI chipsets. I've seen it once with the 780i SLI chipset based boards as well. The worst for this is always boards like the EVGA/BFG/XFX 680i SLI reference boards that I believe were manufacturered by Foxconn.

In essence I believe these reference boards to be of a serioously flawed design. Poor quality components, poor adherence to VRD specifications, badly implemented 6-phase power and a poor cooling solution for the chipsets and MOSFETs all contribute to the problems. The boards also have a number of BIOS issues. NVIDIA cut many corners in later BIOS ROM revisions to ensure better overclocking and memory compatibility Longevity of these boards is passable for 65nm dual cores with modest overclocking. Highly overclocked systems or systems using 65nm quad cores have a considerably shorter life spans. I say this with a fair degree of certainty after personally owning 13 of these atrocious boards and seeing many more of them die in friend's systems.

this man knows his 680i boards. I think you've killed all 13 now?

I had an EVGA 680i board which I had for 13 months, during which it regularly posted at what I thought were modest voltages and between 500 and 515Mhz FSB (90%+ OC).

The other possibility is a bad PSU. Whats the make/model?

Yep. 13 dead in total. Technically, 12 EVGA 680i SLI's and one ASUS Striker Extreme.

It's an Enermax Galaxy DXX 1kw.

Okay I turned it on after a cold start this morning and waited about 10 or 15 minutes. The MCP temp is 48C.

Out of curiosity...have either of you had the issue where the system won't boot if you have the "PXR3" (Auxiliary Power for Graphics) molex connected? I ran into this issue when I built the system. I turned it on for a first boot and I got an error code on the PSU diagnostic display. The code was listed as either an abnormal psu or a short-circuited connector terminal on the mobo. After almost chucking the damn thing out the window I called Evga and they suggested that I run the system without the molex connected. Booted right up. Turns out it just gives an added power boost to SLI configs. I have ben running without it for a year and a half and SLI works just fine....I should have RMAd it back then. :rolleyes:
