SUPER TALENT 2GB DDR2-800 (PC2 6400) Dual Channel Kit Desktop Memory

      

     The price of the Super Talent T800UX2GC4 Dual Channel 2GB kit comes in around $298.00 US Dollars, depending on which vendor you go with. For a few dollars in each direction, there are a lot of ther 2GB dual channel PC6400 DDR2-800 kits from the usual manufacturers such as Corsair, OCZ, G.Skill and Patriot - just to name few. However, from all the other memory available in that price range, this particular kit from Super Talent offers the best enhanced CAS latency timings available.

CAS 4   tRCD 4  tRP: 3 tRAS 8 @ 2.2 volts

     The test system:

Hardware Model
Motherboard: ASUS P5B Deluxe
WiFi Edition
CPU Intel Core 2 Duo  E6400
Video Card eVGA 7900GTX
Power Supply OCZ GameXstream 700

     The memory was installed with the motherboard in an 'out of the box' configuration. All BIOS settings were set to DEFAULT to include everything that deals with memory voltages and timings. As expected, the Super Talent kit did allow the Asus P5B Deluxe to POST and get to the BIOS menu.  This is an important step in memory testing because there are many kits of enhanced latency memory available which will not allow the system to POST, even if the motherboard is in a DEFAULT configuration. This requires the an extra set of memory on-hand which will allow a DEFAULT POST, so you can get into the BIOS and make all the necessary changes before the new memory can be installed. Super Talent has programmed JEDEC specified latency settings into the memory SPD EEPROM, which allow the motherboard's BIOS to detect and select the proper timings.

     To establish a baseline, we're going to set the system up to run the Core 2 Duo E6400 at it's default 2.133 Ghz and use the Aus P5B Deluxe memory divider to run the memory at 800Mhz. The enhanced latency settings of 4-4-3-8 will be configured and I've set the vDIMM voltage at 2.2 volts where Super Talent specifies.

     Now we'll just start adjusting the bus speed, and making any other adjustments necessary (CPU ratio / CPU voltage / NB voltage) in order to maintain stability. A brief stability check  will be carried out with Futuremark's 3D Mark 2005. If the system can complete a run of the three game benchmark tests and the two CPU tests, then the benchmark will be ran with the posted settings supplied in the following charts. CPU ratio, CPU voltage, nor NB voltage will be excluded from the chart, because they have more to do with CPU stability than memory.
