This page is intended as a working zone for some of A.T. Docs I am working on. Thanks for letting me be :)
Advanced Testing: Processors
Set-Up Testing Station
Retrieve the CPU Testing Kit box and CPU Motherboard box
CPU Testing Kit should contain the follow:
- 2 motherboard stands
- 1 Power Supply
- 1 PS2 keyboard
- 1 AGP Video Card
- 1 IDE Hard Drive
- 1 "The little things that count" Box with the following:
- 1 jewelers flat headed screwdriver
- 1 power switch
- 1 tube of ZP heat sink compound *best thermal paste for this process
- 1 hard plastic card for pin straightening
- 2 foam pads
Retrieve incoming CPUs for desired socket to be tested - CPU Socket Descriptions
Match CPU socket to label on motherboard from CPU Motherboard Box
Set-up motherboard on test stand. *IMAGE OF ARRANGEMENT GOES HERE
Plug Power Supply and power switch into motherboard; Power switch plugs into Front Panel connectors on
motherboard. Refer to Motherboard Manual\Google on the Advanced Testing research box if unable to determine appropriate location for switch to plug into.
Install video card if no on-board video is available
Connect keyboard
Connect power cord and VGA cable from Monitor
Unmount heat-sink from motherboard and verify that CPU socket is in good condition
Preparing CPUs for testing
You will need a rag and cleaning agent such as thermal paste remover or contact cleaner
- The can of PureElectronics Contact Cleaner is currently the best option
Apply a small amount of cleaning agent to the surface of the CPU and wipe COMPLETELY clean with a rag.
visually Check speed of CPU, if < 2.0GHz (Intel) or < 2000 model number (AMD) recycle
Visually inspect pins for damage, straighten bent or damaged pins. If there is significant damage to the pins, recycle CPU
- hint: now is a good time to check that the CPU properly seats on the motherboard
Apply a THIN coat of thermal paste to the heat sink (this will need to be re-applied occasionally).
Testing CPUs
Install CPU into motherboard
Place heat-sink in place and clamp down or hold down with free hand
Power on motherboard with power switch
If a post screen appears, the CPU has passed
Else, if no Post screen, such as a blinking light on the monitor, determine probable cause of failure
- Does motherboard support proc? (Check Motherboard manuals/Google on Advanced Testing research box if unsure)
- YES: CPU is bad, recycle
- NO: Set aside for future testing, label CPU as "UNTESTED - UNSUPPORTED"
Power down the motherboard using the power switch
remove heat-sink
remove CPU
Clean thermal paste from CPU
repeat until all CPUs have been tested OK or recycled
using the fine point sharpie, label the CPUs (see below)
CPU Labeling
Labeling process for Intel procs
All information to label an Intel chip is located on the face of the chip.
- across top - proc speed/L2 Cache size/FSB (Front Side Bus) speed
- e.g. 2.8/512/533
- IF FSB = 800, write HTT (Hyper Threading Tech) immediately under the FSB speed
- e.g. 2.8/512/533
- across middle - provide chip name if not a P4
- e.g. Celeron, Celeron D, Duo Core, Pentium D
- across bottom - identify month and year that the proc was tested OK
- e.g. 8/10 for procs tested in August 2010
Labeling process for AMD procs
AMD chips use a model number system to identify proc speed, L2 and FSB. In the "Book of CPUs" you will find a list of AMD procs, locate the model number (e.g. SDA2800AI03BX) from the face of the chip and cross-reference with the list in the binder to find the required information for labeling.
- top right corner - write socket type
- e.g. 754, AM2, AM2+
- across middle - 1st line: Proc Family
- 2nd line: AMD model number
- 3rd line: proc speed/L2 Cache/FSB speed
- e.g. Sempron
- 2800+
- 1.6/256/800
- across bottom - identify month and year that the proc was tested OK
- e.g. 8/10 for procs tested in August 2010
Tracking CPUs
When we have an overstock qty. of 10 for a particular CPU they should be collected and sent to the Online Store.
Place the CPUs in Online Sales incoming location.
Follow the directions at Tracking Online Sales Table for tracking the CPUs.
Finishing Up
Now that all good procs have been tested, labeled and counted they need to be transfered into stock.
Collect the stack of CPUs from Tardis that matches the socket you just tested.
Integrate incoming procs into Tardis stock by Family, then L2, then FSB then proc speed.
Put CPUs back in storage.
Clean the heat-sink and re-seat onto Motherboard.
tear down and store all equipment in boxes and put back.
Know that you are now awesome and capable of testing CPUs Yaaa!!!!
