New discovery to repair hardware with a patch like software

According to Technology Review, Computer-science professor Josep Torrellas discovered a better way to deal with faulty chips: an efficient repair mechanism that treats hardware much more like software, by fixing bugs with downloadable patches. Josep Torrellas invention still in development phase, but his invention could make micro chip production faster…continue reading →

Difference between DDR2 and DDR3 memory

DDR2 Operate at 400MHz to 800MHz. operates at 1.8V 4 internal banks used based on "T branches" conventional topology (OCD) off-chip driver calibration can not deal with termination impedance popular in industry. No Thermal Sensor DDR3 Operate at 800MHz to 1666 MHz. This will reduce read and write time to…continue reading →

RAM Memory Bad Memory Diagnostic Softwares – A Review

Are you facing sudden system crash problems including ugly blue screens without showing any error message. If this is the case then you may have the problem with your RAM or DIMM memory. Although, Memory chips are tested by manufacturers but memory chips are very sensitive and can be crashed by touching it by hand. There are many reason for memory to be faulty:
  • Electrostatic charges or ESD shock from improper handling
  • Frequent AC power surges
  • Dirty and Dusty PC Box internally
  • Operating in very humid and tropical environment
  • Metal contacts between the memory module and the motherboard DIMM memory slot
  • Heat dissipation from other components may cause gradual thermal damage.
Bad memory indication This are the frequent indicators of faulty memory:
  • Failure to boot and accompanied by repeated long beeps.
  • Random system crashes or blue screens during the running of NT,2000 or XP.
  • Blue screens during the install procedure of Windows NT,2000 and XP.
  • Crashes during usage of memory intensive software such as Photoshop,3D Games,Benchmarking utilities .. etc.
  • Distorted Video graphics on the monitor screen
How to check bad memory There are three software that i have checked are available in the market to check faulty memory. DocMemory - Bad Memory Diagnostic Software DocMemory is a user friendly self-bootable PC Memory Diagnostic Software software designed to check all possible memory failures in PC. The memory can be tested by installing software without removing RAM slot from PC. Pros & Cons
  • Software run from floopy diskette. You need to have floppy drive to work this program.
  • Installation process automatically create self-booting floppy disk to check critical errors at boot time.
  • Software claiming that Burnt-In mode" can detect 95% of PC System soft memory failures. check yourself.
  • Software does not change any configuration in your PC
Download Price: Free GoldMemory - Bad Memory Diagnostic Software GoldMemory is a diagnostic utility enabling thoroughly testing mistakeless functions of memory subsystem of PC on process architecture x86 basis. Special algorithms are used, which are very effective and do not directly depend on actual type of memories or chipset used. These algorithms simulate very complicated operations connected with intensive use of the whole memory subsystem. Pros & Cons
  • Floppy and CDROM image available for installation.
  • Program can not determine the wrong part of memory subsystem.
  • Parts of memory subsystem are tested as an unit not separately.
  • Works with 32-bit pattern only.
  • Testing available in three mode QUICK MODE, NORMAL MODE, THOROUGH MODE through command line switches.
Download Price: Shareware $ 29.00 Memtest86 - Bad Memory Diagnostic Software Memtest86 is stand alone memory test for x86 architecture computers. Many features has been planned for this software inlcluding memory testing using multiple CPUs and native 64 bit support Pros & Cons
