bystrup Posted January 25, 2008 Share Posted January 25, 2008 As this is exactly the combination I have just bought - and am having severe problems with (as in no Power On Self Test at all), I'm kind of worried to discover that the combination is absent from the compatibility list? Is this just an oversight and are my problems caused by other things or have I really been severely unlucky? Best regards, Anders Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 25, 2008 Corsair Employees Share Posted January 25, 2008 There is no problem that I am aware of in fact I think we used a MB based on the same chipset to test that platform. A P5K series but I don't think it was that specific MB. What happens exactly? Does it turn on but no post or just beeps? Link to comment Share on other sites More sharing options...
bystrup Posted January 25, 2008 Author Share Posted January 25, 2008 No POST, No BIOS beeps, no video... (the MB has power, though!) I'm not even sure that the RAM / MB combo is the problem. I guess it's more likely a dead MB or CPU, but I was just a bit puzzled that my specific combo wasn't listed in the compatibility chart (whereas all the other Asus P5K board are there) /Anders/ Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 25, 2008 Corsair Employees Share Posted January 25, 2008 Its not as common of a model as the P5K so it was probably just over looked. Link to comment Share on other sites More sharing options...
bystrup Posted January 26, 2008 Author Share Posted January 26, 2008 I found a thread in the ASUS forums which might have some relevance to my situation: http://vip.asus.com/forum/view.aspx?id=20080118135701531&board_id=1&model=P5K+Premium%2fWiFi-AP&page=1&SLanguage=en-us The symptoms are pretty much what I see, although I think that 2.2V sounds a bit rough... Of course I have no way of checking what the voltage is set to. Do you have an opinion on this? Tomorrow, I'll try to dig up some cheap, slow an old RAM and see if I can boot with that...) /Anders/ Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 26, 2008 Corsair Employees Share Posted January 26, 2008 The memory Voltage for the modules you have should be set to 1.9 Volts minimum but I would suggest 2.0 volts if you have problem or if you have more than one set of module and if you have more than two installed setting the NB/MCH Voltage to +.05 Volts as well.

Flashmahn Posted March 16, 2008 Share Posted March 16, 2008 Perhaps it is RAM issue, but have a read.. no guarantees.. there seems to be some weird conflicts with the P5K and certain video card chipsets, mine was a ATi 2600 chipset, but I don’t claim to know the entire list of others that might have similar issues.. I 1st tried other cables, LCD monitors, motherboards nothing.. even another 2600 chipset, and the only way I could get it to POST with a 2600 graphics card is via a DVI to VGA converter on the back of the graphics card as my LCD has the ability to use a DVI or VGA cable.. I suggest anyone with a similar issue try this if you are needing to get the POST and get into BIOS until the conflict is resolved thru driver updates or new BIOS for the MB. This past week I tried a video card from N Vidia and it posted fine with a DVI cable and no converter, go figure! I mean this chipset is designed to work in crossfire mode and that is only ATi chipsets… strange and ATi and ASUS pretend they have never heard of the issue, if you want to get POST then you need to use a VGA plug converter for your graphics card. This is aggravating at best as the motherboard is designed for one to be able to tweak the BIOS, just ridiculous that one must put this stupid connector on every time should they want to get in BIOS. Other than this without this connector the PC will usually boot in 30 or 40 seconds direct to Windows welcome screen. Link to comment Share on other sites More sharing options...
