I have an emachines c3070 that I am just now trying to overclock after several years. What temperature monitor software gives the most accurrate readings for the FIC K7MNF motherboard? I've been trying motherboard monitor, but that tends to give anomalous readings, sometimes reading below 0 C (ambient is always above 10 C and I'm using the stock emachines heatsink.) Perhaps these anomalous readings are an unavoidable part of the sempron temperature monitoring hardware, but if not I'd like to know what software to use.
This motherboard uses the nforce2 chipset, and a sempron 3000+ processor using ddr400 and a 166mhz FSB and 1.992Ghz stock cpu speed. This is a Barton core.
Here is a cpuid dump (overclocked):
Processor 1 (ID = 0)
Number of cores 1 (max 1)
Number of threads 1 (max 1)
Name AMD Sempron
Codename Barton
Specification AMD Sempron(tm)
Package Socket A (462)
CPUID 6.A.0
Extended CPUID 7.A
Core Stepping
Technology 0.13 um
Core Speed 2385.0 MHz (12.0 x 198.8 MHz)
Rated Bus speed 397.5 MHz
Instructions sets MMX (+), 3DNow! (+), SSE
L1 Data cache 64 KBytes, 2-way set associative, 64-byte line size
L1 Instruction cache 64 KBytes, 2-way set associative, 64-byte line size
L2 cache 512 KBytes, 16-way set associative, 64-byte line size
FID/VID Control no
Features
K7 Thermal sensor yes
summary of my overclocking journey thus far:
The emachines c3070 comes with an aluminum heatsink with thermal tape (which I cleaned off with isopropanol) and the fan it came with was:
# Fan: Delta AFB0612MC 60x13mm
# Dual Ball Bearing
# Input Voltage: 12 VDC
# Rated Current: 0.11A
# Power Input: 1.32W
# Speed: 3600 RPM
# Airflow: 18.15CFM
# Compact design
# Noise: 32.60 dB-A
I have replaced the fan above with one of the 80 mm masscool fans that was on sale at new egg recently, 31 CFM, and remounted the heatsink using AS5. The 80 mm fan overhangs the heatsink, but the 60mm fan didn't cover it completely. So far it is stable at idle. I am pessimistic about it being stable under load as this motherboard does not have voltage modification options, nor does it support FSB speeds between 166 and 200. It also does not support changing multipliers. On the plus side, I have thus far used less than $2 in materials to improve the cooling, since I still have AS5 left over.
Edit: prime95 found an error after 64 seconds, so the overclock is not stable, and I'm giving up, as it isn't worth more resources for such an old system when I'm probably going to have to get a new motherboard and cpu when starcraft 2 comes out anyway.
Thank you o1die. I am currently using MBM5 and it is showing my three temperatures (back at stock speeds) as 28, 37, and -11 C. The ambient temperature is 60F so I doubt the -11 C is accurate, though that is the number that changes the most under load so I had assumed it to be a cpu temperature. Perhaps it's a flaw in the motherboard's bios in reporting the temperatures, it's not exactly an enthusiast board. I suppose if MBM5 doesn't give accurate numbers, nothing will. Since I'll never be stable at 2.4Ghz without voltage mod anyways I suppose it doesn't matter.
