Hey guys- wonder if you could help me out with a little problem i've been having. A coulple of weeks ago I bought a new Gigabyte GA-81K110 Rev 2.0 motherboard. With Motherboard Monitor 5, all of my voltages were a little low but still within 4-5% of what they should be; all except my +5v that is. With my 350W Foxconn power supply, I was reading around +4.20v using mbm 5 and confirming that low number with SiSoft Sandra. I didn't bother to use a multimeter to check the voltages, and instead opted to just replace the power supply with a quieter and more powerful Thermaltake Silent Purepower 480W.
With the new power supply my 12v and 3.3v readouts with MBM5 are near perfect: +12.22 and +3.37, but the +5v is still reading really low: +4.21v. I decided to read the voltages with a multimeter I picked up at Radio Shack, and this is what I found:
using a molex connector:
+12v: +11.99v
+5v: +5.15v
using the atx power header to the board:
+3.3v: +3.42v
+5v: +5.14v
+12v: +11.97v
As you can see, these voltages are all very nice.
Should I be worried about the low +5v readout after this?
Is the motherboard really getting the full 5v or is it the 4.21v that Sandra and MBM5 are reporting?
Is there another way to check this or should I give in and call Gigabyte tech support?
Thanks for the help!
Here's my setup incase that info helps:
P4 2.4GHz B0 stepping oc'd to 3.0GHz (167 x 18)
Vcore normal for this proc is 1.50v, i'm running it at 1.75v, but adjusting voltages back to normal and running non-overclocked doesn't bump up the 5v line.
GA-81K1100 Rev 2.0 MB
2 x 512 MB DDR running dual channel (mismatched generic: 1 PC2700, 1 PC2100)
1 WD 40 GB 7200 rpm HD
1 Maxtor 10 GB 5400 rpm HD
1 Floppy
1 Sony CD burner
1 Creative DVD-rom
PNY GeForce FX 5900 Ultra BIOS Flashed to FX 5950 Ultra
Sound Blaster Audigy 2
2 case fans
Thanks again,
Jason
