This old board, GA-EP45T-UD3P, has been trouble free for years; ran Win XP without issue. It's my home workstation, finally had to update to Win 7 x64.
For preventive maintenance I cleared CMOS by installing a new battery and installed a new hard drive; all other hardware unchanged. Adjusted settings in the BIOS; RAM timings @ auto but did set RAM voltage to 1.55V (I remembered I had to bump it up originally). RAM spec is 1.5V.
I started the system and it did the start/stop loop during POST. I remembered this also happening originally when I first used the board, I bumped the RAM voltage to 1.6V. Win 7 loaded fine as did software, updates and my personnel data.
I started having some random BSOD's, sometimes at the welcome screen and others while browsing with IE. I set the RAM voltage to auto and checked PC Health; it showed 1.744V, that's a bit high! I installed HW Monitor, it confirmed 1.744V. That makes sense, HW Monitor and PC Health I assume use the same sensor/sender for data?
I manually set the RAM voltage again, PC Health and HW Monitor show 1.664V. I ran "many" Memtest passes, no errors. I have not had a BSOD in 24 hours; only time will tell. All other voltages shown in PC Health and HW Monitor, CPU, 12V, 5V, 3V match in both and appear normal.
My question: any documentation or known issue of this series motherboard displaying false high RAM voltage in PC Health?
Thanks.
