Hi, a buddy of mine got a new AMD build we put together last night and the computer is giving us trouble. This is my first AMD build in around 7-8 years, so I need some advice on a few things. The specs are: CPU: Phenom II X3 710 @ Stock with the Zalman CNPS-7500Alcu cooler (MX-2 paste). Motherboard: Gigabyte GA-MA770T-UD3P Memory: 2x1Gb OCZ DDR3 1600Mhz CL7-7-7-18 (1.9v sticks, ugh), running on default 1.62v at 1066Mhz currently, unganged, with 9-9-9-30 timings. HDDs: 1 Western Digital 80Gb HDD (Ubuntu install), 2 Western Digital 160Gb HDDs (Vista Business 64-bit on a partition on one drive). PSU: FSP Epsilon 500W GPU: Powercolor HD2600XT 256Mb GDDR4 Some random case. All BIOS settings on auto/default, ACC is off. Vista installed just fine, the computer boots just fine but the system won't remain stable under Linpack, producing errors around the 3rd or 4th loop, it did pass around 20 minutes of Prime95 (Very short I know, we'll let it run more of it today when I get off work). I am sure as heck hoping there's nothing faulty with it because this is a budget build using lots of spares so troubleshooting will be annoying as heck (No additional mobo or CPU on hand and my i7 rig is at my parents' place, meaning that at least for a few days we got no additional DDR3, either). I tried giving the DIMMs more juice (But did not touch VDIMM VTT), to no avail. Temperatures reported by HWMonitor are around 30c idle and 46c LinPack load, so assuming it is reading temps accurately there should be no overheating issues, the motherboard components also keep below 56c under load, except for some sensor on the motherboard which seems to be stuck reporting 79c regardless or load, so I assume this is a faulty sensor. My questions are: 1) Any general tips or ideas (Other than the usual - leave one HDD, one stick of RAM, etc usual troubleshoot routine, this will be attempted once I get off work today, we just barely got it running at 2am last night and I was at my desk at work at 8am). 2) Any good accurate temp reporting software for AMD builds ? I have no experience with this, so I have no idea whether HWMonitor is reliable with AMD rigs. 3) Is there any stress testing software for linux ? Since we got two OS installed, we could make sure it isn't some OS related issue, although it is unlikely. 4) Any general ideas as to what might be causing it aside of some hardware fault ? Maybe some of the default settings aren't good enough, if so, what are good ideas to try and tweak to get it running. Thanks a bunch to anyone who'll help - This is rather annoying.
