I purchased the Mushkin XP2 PC2-6400 2GB 2X1GB DDR2-800 CL 4-4-3-10 240PIN DIMM Dual Channel Memory Kit from ncix.com, and am using it with an Asus P5W DH Deluxe mobo.
The mobo was autodetecting the RAM as PC2-5300 in the POST. In bios, if I went to look at what it autodetected the timings at, it read 5 4 4 15 (4). I'm not sure what the last value is for.
I set the first 4 values for the RAM to 4 4 3 10, as recommended.
I asked in the Mushkin support thread about it detecting the proper frequency of the RAM, and though I did not receive a reply from the Mushkin representative, I did get a reply from someone else with the same RAM and mobo.
He told me it was in the jumperfree setting, that I had to set the AI overclock and choose 800mhz RAM.
I set the jumperfree setting to manual, set the DDR2 frequency to 800mhz, saved, and exited.
On POST it showed PC2-6400 RAM Dual Channel Interleaved. Great, fine.
But then, I couldn't get into windows, it just gave me a black screen after post.
So I rebooted, and after the first beep, it shut off. Now I get to panic.
Powered up again, got into BIOS, tried to change the settings back to auto, but BIOS froze. Powered up again, froze at POST. Powered up again, and before post got constant beeps. And it goes on, picking any one of those endings after I power on.
So I take one stick of RAM out, power up, and it shuts off before POST. I try again, get into BIOS, set the DDR2 Frequency back to auto, and the jumperfree setting back to auto, save and exit. Boot to windows no problem, though I have yet to put the 2nd stick of ram back into the computer.
I put the second stick in, powered up, and it once again shut off after 1 beep (signalling everything is ok). Tried again and it worked, and has worked since.
Now I am running the RAM at its advertised timings, but a slower frequency. Tom D from Mushkin said that they have 80 or so test P5W DH mobo's in house, and that it is perfectly compatable. I don't doubt him, but something is wrong, and it's been a week since I posted in their thread with no response.
Thanks guys.
