ASUS A7N8X-X Update
Well, I’ve gotten the new power supply and it sure has helped. Here is where I am:
# System runs stably at 198MHz, but won’t pass Prime95’s validation suite. Backing down the memory to 191MHz seems to make the system super stable. I’m guessing that it is the cheap RAM that is the problem. The system won’t run stably at all at 200MHz even with the CPU running at 166MHz.
# It sure does run hot! Motheboard Monitor and Superfan both report temperatures of 75-77 degrees C when running flat out overclocked at 191MHz FSB. The thermal limit is just 85 C,. This is for the sensor on the CPU die. The socket reading is more like 50 degrees C. I’m not clear on how accurate these readings are, but it does run hot. I’m using the Thermaltake Silentboost, which is very quite BTW.
# Antec TruePower 550. Wow, this is a super quite unit. It monitors itself and turns its fan on as needed. The Enermax 350 that I had was supposed to be motherboard controlled in terms of fan speed, but it always ran flat out on the ASUS A7N8x.
# Disk runs very hot when spinning. The new Western Digital WD2500PB has a thermal sensor in it that the system can read. Gets as hot as 55 degrees C when it is defragging. Don’t know what the thermal maximum is, but it is too hot to touch when jamming away.
# Overlclocking of the video card is also stable running at 455MHz Ramdac and 815 MHz for the video memory. This is compared with a normal 300/700 system.
# Benq FP991. Got this monitor. Wow, it is amazing. Running it in portrait mode. The 19 inch monitors are just right for a full page display. Still not as elegant as the old Radius monitors on the Macs (whcih would sense when you pivot them), but pretty neat.
# Next steps are to power up the Promise RAID controller. This will give me a sense as to whether it is this controller that is causing IDE to hang. Rerun stability tests
# Also installed a USB 2.0 connector set in place of the floppy. This will make it easy to put a USB floppy in for emergency booting and also to stick a USG Flash drive in for personal data.
