ASUS P5W DH - Problems + Fixes Thread

[AHolland]

Thanks to the people that responded to my question.

To answer, I have disabled everything that I could, including the hyperpath, etc. I hae also tried core voltages up to 1.5 with no luck. I did notice that the board does not seem to recognise my 320gb drive. I boot off of a raptor 150gb. I also have a couple of 500GB's in a mirror raid config. The SATA2 connector is not there so I have the 320gb drive connected to one of the other sata connectors.

My board is the 1.02 version but I have full control of the MCH up to 1.85, vcore control, etc. Is there some issue with the board 1.02 version.

And on the OE issue. Can someone lay down a quick paragraph on what this discussion is about?

Lawrywild could you append your first post to include some of these issues? It would make an easy point to point people to who are asking these same questions. Over time it would (and is already) be a go to point rather than having people like me asking the same questions over an over again. We can be told to read the forums, but with 225+ pages it becomes a lot to go through.

Thanks guys

Here is also a quick one. Where the heck is the motherboards serial number. I may send this board back to the manufacturer, but because I bought 2 at the same time from 2 different vendors, I have to figure out which bill to use.

In short, I made up a board from a friend and the local vendors only had one in stock at each of the stores so I had to run around getting two of them.

Thanks

Bro please try upgrading your bios to 2004. My board came with the 1901 and it was not nearly as stable as it is now with my current OC settings... I really believe the newer bios do a better job but that is just IMHO....

Okay, for arguments sake I ramped up and tested the system on some of the highest voltage settings.

If I put the vcore voltage to 1.6 volts the system blue screens. If I bring it back down again it's happy. In testing voltages between 1.3 - 1.5 there is absolutly no difference. I ahd previously tested these settings overnight and found them all stable up until passsing the 333SB level. It's interesting to see that the system became unstable if the voltages went too high.

I also tried putting up the voltages such as MCH to their highest levels (1.85). Again the system is okay until 333 FSB and then unstable past that.

I'm just going to have to accept that either the motherboard or the CPU is limiting the overclock. I have worked in the electronics world (design and manufacture of PCB's, robotic board manufacture etc.) for 15 years. It is extremely unlikely that a chip will work to a specific level and then completely not work at a very fine different level. There is always a grey area in between when chips get flakey. My system is telling me that there is some other outside influence making the 333 - 334FSB limitation. I just wish I could figure out what it is. I've checked and rechecked that all the components are properly soldered, seated, etc. There just can't be something about my board that would not show up on other peoples boards to make this specific limitation.

I forgot to add that the temps under load were in the low 50's

Arrghh

My system was never stable with 1.85 MCH. 1.75 is ok but again my mobo does not even like that but raising my FSB to 395 I have to run it there or it will not post... I like to keep it @ 1.65 and that gives me the most stability....
