  1. I just wanted to start a "Thank You" thread for RGone, ExRoadie, Angry Games and the rest of the DFI support staff (Ricky et al) for the terrific work they do here and behind the scenes with our DFI products. Not enough appreciation is expressed to these fellows who put up with the frustrations of trying to help those in need. People come here for help, and these guys deliver! :angel: Gentlemen (ladies too!), this one is for you: Thank You!
  2. I have a suggestion: why not include the above information (e.g. the fickle nature of high power psus) in the first part of the sticky post for power supplies within recommendations and hot deals? Perhaps others who are beginning their builds might benefit from this information and not waste everyone's time RMA-ing boards and psus if they encounter this problem?
  3. To my knowledge at least three diferent OCZ power supplies were tried on my board- all of which exhibited the same cold boot problem (RMA was able to reproduce the problem in the lab). I seriously doubt that these power supplies are defective in some way- the odds are just against it. To quote ExRoadie "Sometimes good hardware goes bad or two pieces just won't work together."
  4. Well, ExRoadie, I have my facts straight and I never made such a blanket statement. If you were paying closer attention to my wording (see above) you might not have jumped on me so quickly. Ignorant, lol, did you forget who started this thread?
  5. Same memory I use- no problems running at advertised specs on my Expert board. See my signature...
  6. Update on my cold boot status: I actually sent my board back to RMA for a second round of analysis regarding the cold boot issue. The staff wanted to add a couple of capacitors to the board as a possible fix. When the board came back I examined it very closely and could not detect any additional capacitors anywhere on the board, I suppose it is possible that some were replaced with caps of different rating or manufacture. Anyhow, same result with my OCZ 600w powerstream- no go on cold boot! Finally I broke down and bought an Antec Neo 550 HE psu and the board now works perfectly. For some reason certain Expert boards just will not work properly with the OCZ power supplies. Now I have a spare $150 psu that will not work properly with my board. Should have followed my instincts on this build and gone with Antec from the beginning instead of reading too much into the psu recommendations for the Expert. Live and learn...
  7. Update on my cold boot issue- I contacted DFI about the rma of my board. They were able to reproduce the cold boot problem with an OCZ power supply. They mentioned that several power supplies were tested: OCZ, Enermax and two different Antecs. In my case the OCZ made power supplies seem to be the issue- they got the board to boot perfectly with the Enermax and Antec units. Recommendations for me are to switch power supplies, at least temporarily, while DFI and OCZ work on this problem. Perhaps this information may help others.
  8. Corsair says the ram timings for the C2 and C2PT XMS series are 2-3-3-6 which is what I'm running. I have to say there is not much performance difference that I can detect between default (3-3-3-8) and the factory recommended settings (2-3-3-6). Make sure you set the correct number for the correct ram timing variable- I think in the bios they re listed out of order (2-3-6-3).
  9. ExRoadie that does sound similar to the issue I have except that the system self powers off quickly (by power supply lockdown?)- about one or two seconds. By the way, do you know if I can obtain information from DFI concerning my rma #DFI-4254? The same board I sent out came back, no paperwork or explanation as to what was done and no obvious signs of any repair. Kind of left me hanging since it exhibits the same problem it was rma'ed for...
  10. I'm running the platinum series of the same memory at advertised CAS2 with no problems. You might want to try flashing the bios to 12/7 version and see if the memory will cooperate.
  11. I'm running that exact memory! No problems yet, running advertised cas latency too...but not overclocking.
  12. RGone, thanks for the info- I can hang, no problem. I really like this board and do not have issues aside from the cold boot problem. I know how corporations operate- after a month wrestling with this problem a week to 10 days sounds pretty quick to me . BigKohones, you got lucky with the A8N32 if you have no issues. I was considering that board before I got the Expert, but after reading up on them I found they have their own unique set of problems. Plus at the time no one had them in stock.
  13. Hey RGone, I hear ya. I've already tried a cheaper psu model (Raidmax) on this board and it worked fine (in other words no cold boot issue). Unfortunately it did not have all the proper connectors for the board (1/2 of the 8 pin connector- aka P4, no pcie conector) and was not stout enough (~400w) to run all my hardware and have any margin for error, otherwise I would be using it! My rma request for the board was out of frustration thinking it had to be something on the board...maybe not. I ran this board for at least two weeks after purchase before I broke down and got the rma authorization (this build was started right before Christmas). I work in the industry (since 1995) and fix computers nearly every day so this is not new territory for me. My beef is popping ~$150 for a sweet OCZ psu only to find it does not work properly out of the box with this board even after all the acclaim and hoopla associated with it. Since I rma-ed the original 520w one to OCZ I cannot return the 600w they sent me to the original vendor for credit or refund- so I'm either stuck with it, sell it on epay for a loss or keep it around in case I build something else that it plays nicely with. I'm interested to find out your results...let us all know!
  14. Figured I'd chime back in now that my Expert board has come back from rma. Result: Same issue, no boot after proper shutdown from windows or power off with the case switch. No explanation came with the board on arrival back from rma. Same board, serial numbers match. Perhaps all that was done is put in a new bios chip, seems to have a gold or yellow dot on one corner. For all I know the board was tested and shipped right back. I also rma-ed my psu to OCZ and they sent a nice 600w in place of the 520w. If this problem is directly related to power supply startup voltage variance then why the heck is OCZ the number 1 recommended psu for this board? That recommendation is the sole reason I purchased an OCZ psu and it is posted prominently on this site. Interestingly enough my board is also a revision AA0. What next, just learn to live with it?
  15. Tried upping the ram voltage to 2.8- no change. RMA here I come... Guess I'll have to buy some cheap board to use while I wait on the rma process.
  16. Latest Update: Got my new OCZ psu from rma- they sent me a 600w (upgrade)! Thanks go out to the OCZ crew. Anyhow- my cold boot problems are back with a vengeance. With the cheapo raidmax psu the board would act normally and cold booting was never an issue. Now I have to turn off the psu rocker switch and let the board standby light go out before it will successfully power up again (the old momentary fan spin and diag leds to 3 then self power off). I'm suspecting that having the second half of the 8 pin board power connector hooked up is somehow related to this problem (the cheapo raidmax only had the P4 connector and it worked great). Now what?? Rma the board? This shipping and waiting game is getting old. Grrrrrrrrrrrrr
  17. I seem to have found a reprieve from the cold boot issue- not sure whether it was my OCZ powerstream, the board or the bios. The powerstream went to the shipper today for rma and I hooked up a raidmax 400w (24 pin atx, no 8 pin just P4) as a temporary. After swapping the psu I could get the board to cold boot following shut down from windows but not after powering off by hitting the case switch. Found the new bios post this a.m. and flashed to 12/07- now the board cold boots perfectly. ??? Not sure if the bios flash fixed the problem, if the board finally got "broken in" or if the problem will manifest again after I put the upcoming replacement ocz powestream back in. Time will tell...

  19. I'm not sure why you would think that. This site is where I made my choice: Expert PSUs Besides, I can make my system boot and run windows just fine with a cheap ($39) Raidmax 420w psu. ???
  20. Update: Tested my board with a cheap Raidmax 420w psu. With this power supply I can shut down from windows and successfully cold boot, but if I power down with the case switch after post it will not cold boot. WTF???
  21. Quick and dirty test of my OCZ powersteam psu passed- shorted green and black wires, turns on every time. I'm thinking this may be a bios setting problem or a bios version in need of revision. Hopefully this will not turn out to be an rma issue.
  22. Unfortunately it is not just Enermax power supplies involved with this issue. I have exactly the same problem with the highly recommended OCZ powerstream 520w on my Expert board. I have quick and dirty tested my psu by shorting the green and black wires- starts and cuts off perfectly each time. The only way I can get my system to boot is by turning off the psu rocker switch until the board standby led's are off. Under normal circumstances that leads me to believe the psu is defective. In this case I'm not so sure... I suspect there is some error/ setting in the bios that needs to be tweaked for boards experiencing this problem- either that or we might have defective boards. What worries me is this problem seems oddly similar to the ram voltage issues NF4 ultra D boards sometimes encounter. I just hope there is a bios fix for this Expert issue soon.
