I’m wondering if you can help me with the following memory problem.
I just installed a 2 GB kit (2 x 1GB) of Kingston Hyper X PC8500 (1066 MHZ) DD2 RAM (KHX8500D2K2/2G) on my Asus P5B-E motherboard.
I went into the BIOS and manually entered the speed (1066 MHZ) and timing (5-5-5-15) consistent with the memory specifications sheet. However I went to change the voltage to 2.2 (which is what the specifications sheet states is required) but the closest options in the BIOS are 2.15 v or 2.25. I wonder if this is a BIOS quirk – it seems quite odd.
I tried running the memory on 2.25 v but experienced instability – the PC would sporadically reboot while in a game or in windows. This seems to be a PSU related problem, perhaps a lack of power? Is it possible I was pumping too much power into my memory for my 650 w PSU to handle? What else would explain the random restarting?
I haven’t tried 2.15 v but suspect this will be under powering the memory and consequently I won’t post and/or make it to windows. The PC wouldn’t post when I set the memory voltage to auto.
In the end I gave up and opted for setting the memory at 5-5-5-15 timing at 899 MHZ at 2 v. The memory works well at these settings.
As well as the above questions, obviously I’d like to get the memory working at full functionality. Any ideas?
Do I need to upgrade my PSU, is my Asus P5B-E simply inadequate for the task, or is there some quirk in the BIOS that I can manipulate to get the memory going?
