Asus P4P800E - Deluxe Problems?
Hi,
I just read a review at the below link http://www.epinions.com/content_141363285636 and the person said, "I turned to Google to do some research and found other instances of the same issue. It turns out that this revision of the board (1.2) has an issue telling that the extra 4-pin connector from the PSU is connected, so it thinks it's not and doesn't attempt booting. They also reference that rev 2.0 of the board has no such problems. The only hitch - rev 1.2 and rev 2.0 are sold interchangeably as the revision number is not marked anywhere on the packaging and they have the same UPC - so getting a 2.0 board is a roll of the dice." Asus refused to replace the motherboard with a rev 2 board even though Asus knows this is an issue with the rev 1.2 board. Not only do I find this disturbing on Asus's part but totally unacceptable customer service and makes me really question whether I want to purchase a product from a company that exhibits behaviour such as this! I have had enough crappy service and issues with big computer companies and I don't want to buy a product with empty promises of customer service and warranties when in reality there aren't any! Anyway if people could shed both good and bad experiences with this motherboard and whether I need to worry about buying this motherboard or not that would be very helpful! Thanks RC |

Thanks RC Asus doesn't need to replace the board. As this thread explains, Asus had to figure out what the problem is with the 1.02 revision of board, so that when the board is RMAed, they could change a component value so it would work with the Antec power supply. You get back a 1.02 rev board that works, and everybody is happy. http://abxzone.com/forums/showthread...2&page=3&pp=15 As was pointed out, their policy is to "not do free upgrades". This is because the overclocking community would have a steady flow of boards going through RMA, so they could have the latest and greatest. It is precisely because the RMA process has so few restrictions on it, that "rev bumping" has to be made a strict no-no. Looking at the ADP3180 voltage regulator datasheet, it has some sophisticated overcurrent detection circuits. The power up sequence is complicated, by the fact that different power supplies have slightly different characteristics (ramp up waveform, ramp time, rail sequence, sensitivity to inrush current demands from the motherboard). It sounds like the 1.02 revision of the P4P800-E Deluxe had the delay circuit set to a too low threshold, such that a power supply that ramps +12V slowly, causes the Vcore converter to fail to achieve a "power good" condition, before the timer that detects trouble trips. In other words, a power supply that develops a "rock hard" 12V output instantly, would cause no problem for the motherboard. A power supply that gently raises the output, causes the ADP3180 to declare there is a problem, and because it is a latch-off device, the only way to recover from the problem, is to shut off the power supply (and, of course repeat the same sorry mess). There is a spec for ATX power supplies (formfactors.org usually has these, haven't checked to see lately if the specs are still there). I have rev 1.3 of the spec here, and the max time for a supply to ramp is 0.5 seconds. If the Antec (Channelwell Technologies) supply is taking longer than this, then Channelwell is at fault. If the delay circuit on the ADP3180 of the rev 1.02 board was tripping at less than 0.5 seconds, then Asus is at fault. I don't think I'd describe it as "the motherboard didn't recognize the connector". Reading the datasheet, the converter shut down within a very short time, because it thought there was a fault, and considering the power levels involved, and the fact that you can burn a hole in the motherboard with that circuit, it is a good thing that the shutdown function works.

Hi everyone
I have this board and im having hells own trouble with it now im not the brightest person when it comes to all of this but none the less built my own new system about 2 weeks ago and have regretted it ever since im running it with a p4 2.8e and 512 RAM 400w win 98 se (i hate xp with a passion) .. not using the raid controlers tho as i only have my dodgy old 80g on ide for now .. but all the bios is set correctly for this as outlined in the manual im having slightly different issues with it ... hanging and reseting of its own accord and RAM errors with 3 different perfectly good sticks .. oh and a grumpy bios that wanted to be reset from the disk - i nearly cried when i saw that one flash up.. i did however have quite a good response from their customer service team ... saying simply if the store that i purchsed it from varified that it was faulty but was unable to replace it that ASUS would (i still have the guys name and phone number in sydney ifanyone is interesed hahaha) just another tid bit of info there for the interested R.

But the machine has been rock solid stable so far, maybe its a problem with MBM5? There is a fault in MBM5. I have 11.93V and MBM5 says 12.54V. I got digital multimeters to compare with. Other programs don't tells that high voltage. |
