hey everyone!
im on here because my computer freezes almost every hour on the hour when i have 2 GPUs installed, with 1, its tolerable maybe 3 or 4 hours as long as im not gaming. i just bought this computer from a buddy who was too lazy to trouble shoot the issue, so i figured id take the risk, its about a year and a half old Alienware aurora R3 (spec below)
so ive downloaded "CPUID HWMonitor". the numbers look a litte off from what ive seen, ill post it here.
system specs:
crossfire radeon hd 5870s (doesnt freeze up computer as often with only 1 5870 installed)
i7 2600k 3.4Ghz.
aurora R3 alienware motherboard, not sure on which one that is.
6Gb ram 1600Mhz.
850w psu.

specs for CPUID HWMonitor.
+3.3V reads Value=3.296 min=3.248 Max=3.312
CPU CORE reads Value=1.368 Min=1.362 Max=1.276
Vin2 reads Value2.304 Min=1.282 Max=2.320
Vin3 reads Value=1.294 Min=1.282 Max=1.305
+5V reads Value+3.784 Min=3.742 Max=3.868
+12v reads Value 16.192 Min=14.872 Max 16.192
Vin6 reads Value=3.472 Min=3.424 Max=3.488
VSB3V reads Value=3.296 Min=3.248 Max=3.312
VBAT reads Value=3.264 Min3.232 Max=3.280.

Temps for that are (idle)
TMPIN0 reads Value 107 F
TMPIN1 reads Value 91 F

any help at all with anyone who knows how to read psu voltages would be great, the big one i saw was the 12v bus was really high, im not an expert on PSUs so thats why im here. thanks for the help!

ive also been told it might be a mother board issue? any input on that would be helpful too! thanks!

ok, so which numbers dont look right with the software version if i may ask? so its safe to say my +5v and my +12v numbers look off in my 'software' reading correct? and if those read the same or close to the software readings, its a bad psu.?
thanks for the quick response!

yes but i am also dubious that those are acuret because i doubt your computer would work if they are as far off as the sofware reading sugestions so thats why you should confirm it with a multi meter and while your at it check the make and model of the psu

CPUID HWMonitor doesn't properly support the sensor chip on your motherboard.

If your +5V and +12V rails were really putting out those voltages your system would be completely non-operational.

Download the freeware utility HWiNFO64. At least this utility reports the same voltages that the motherboard's BIOS reports.

ok so i read it out finally

all my 3.3v are reading 3.26v
all the 12v are 11.99
and the 5v=5.10

so does that rule out my psu completely? what should i do next? thanks!

What's the brand and model number of each of the memory modules installed on the motherboard?

What Operating System and version is installed?

What is the graphics card driver's version number?

so ive removed a stick of ram last night and let it run (i took it out of dimm 3, so i now have a 2GV in dimm1 and dimm2), did some tests this morning with heaven benchmark because it always freezes with that. also i took out some ram and noticed it says pc3-8500U on it. which is definitely not 1600mhz, it is actually 1033 from what ive researched. so ill be upgrading that this weekend. but so far after i removed the stick of ram, its been running about 7 hours idle (new record) and about 3 hours in use.(so far its looking good)

all writing found on ram sticker:
made by hynix. 3x 2GB 2Rx8 PC3-8500U-7-10-B0
HMT125U6BFR8C-G7 N0 AA-C 1007

i have windows 7 home premium 64 bit installed from the laptop alienware windows 7 disc (sold the laptop a while back)

so im looking in AMD catalyst control center. this is what i have for versions
Driver Packaging Version 13.152-130830a-163178c-ATI
catalyst version 13.9
2D Driver Version 8.01.01.1331
Direct3D Version 9.14.10.0984
OpenGL Version 6.14.10.12422

Supported Memory:
Up to 16GB Dual Channel DDR3 SDRAM at 1333Mhz - 4 DIMMS (PC3 10600)
Up to 16GB Dual Channel DDR3 SDRAM at 1600Mhz - 4 DIMMS (PC3 12800)
Up to 8GB Dual Channel DDR3 SDRAM at 1866Mhz - 4 DIMMS (PC3 15000)

Don't mix different spec'd memory modules. The DIMMs should also be rated for 1.5 Volts and not any higher.
