At some point during the calculation the calculation was corrupted.
Either it was because of a hardware issue: RAM, CPU, MB, PSU
or a software issue: some other program (user application, device driver, OS )
has affected/disrupted the calculation.
If it affects Prime95's calculations it probably affects other programs
ie Spreadsheets, TAX calculation, CAD etc.
Hardware :
If the CPU gets too hot
CPU fan/heatsink coated with dust, fans not working/failing, air inlets blocked,
room too hot (unlikely), thermal paste between CPU and heatsink dried out or not sufficient.
Support chips/MB
coated with dust
Power supply
not supplying correct voltages, too many other devices drawing power,
PSU failing.
PC not getting good electrical input ( spikes, surges, brownouts, noise)
RAM
RAM has errors, static shock corrupted contents of memory.
Software :
some program is affecting the FPU, either modifying flags/precision mode or
corrupted values ( MMX used without proper saving of complete FPU state)
To test
Software: try running in safe mode without running any other user applications.
(many devices drivers are replaced with a generic windows device driver)
Hardware: (turn off PC first) clean out PC (blow out dust), clean off fans,
make sure air inlets not blocked.
Use good surge suppressor or even better a UPS (uninteruptable power supply).
Test RAM with a memory testing program.
What version of Prime95 are you running ?
What OS ? Windows 95,98,98SE,ME,NT,2000,XP,2003 or Linux
Stress testing or running a Lucas-Lehmer/Double checking test to try to find a Mersenne prime ?
大概意思是硬件过热,与其他软件冲突
解决办法:在安全模式下单独运行PRIME95
清理CPU风扇或更换
用其他测试软件测试CPU和MEM的稳定性 |
