  1. The first and third slots are tuned for 1333Mhz and the Northbridge chipset latencies are set tighter at that speed, and give better performance at that speed than the looser chipset latencies of the second and fourth slots. Running 1600 at 1333 won't hurt anything. You might want to check out the enthusiast performance forums. http://www.overclock.net http://www.ocforums.com are two very good forums.
  2. The manual is in error. The two orange are Dual Channel slots and the two brown are dual channel slots. For overclocking the two brown are the best slots as they are tuned for higher speeds. The yellow colors are indicative of JEDEC DRAM voltages which are 1.5v. This is higher voltage DRAM as specified on the modules. You can buy vanilla JEDEC Dram if you want lower voltages. You are warranted for up to and including 2.0v on those modules. No need to buy high end DRAM if you are not going to run overclocked in my view. http://www.ncix.com/products/index.php?sku=28603&vpn=TW3X4G1333C9DHX&manufacture=Corsair For a two slot 1333 DRAM configuration. Set the modules to the Slot 1 (Closest to the CPU) and slot 3. (Orange Slots). Enter your BIOS and set to these values: Download Memtest Version 2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Download CPU-z from Here .Please Enter your BIOS and set to these values, save and shut down.

If stable enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs. If you want overclock settings for 1600Mhz on the DRAM and 400Mhz on the CPU, please request.
  3. I'm not going to get into a why guessing game. You can contact Asus for those questions. http://www.slashgear.com/gallery/data_files/7/4/ASUS_P5E3_Deluxe_motherboard_2.jpg This is your motherboard. I will give you instructions if you will follow them. Otherwise your best bet is to contact Asus and ask them why they have....
  4. If three pass and one does not, and you have used the same slot to test, then yes, you are advised to RMA one of the pairs. You must RMA two matched modules so that you receive two matched modules back.
  5. Set to 1.30v if you are worried. Keep in mind that you are using 4 dimms. Did they use 4 dimms in the testing you post to?
  6. Using 4 DRAM modules in the board is far different than using 2 DRAM modules. You are advised to DROP the DRAM bandwidth to 533Mhz when populating with 4 667 Modules. You also need to increase your CPU FSB from 200Mhz (800 QDR) to 266Mhz (1066Mhz QDR). Download Memtest86+ V2.11 from--->Hereand extract the ISO image. Burn the ISO image to an CD-ROM disk. Set one stick in slot 1 (Closest to the CPU), enter BIOS, load setup defaults, save setup defaults and set to these values. Enter your BIOS and set to these values: AI Overclock Tweaker Configure System Performance Settings Ai Overclock Tuner = Manual CPU Ratio Setting = 15 FSB Frequency = 266 PCI-E Frequency = 100 FSB Strap to Northbridge = 266 DRAM Timing Control = Manual DRAM Frequency = DDR2-533 DRAM Command Rate = 2N DRAM Timing Control = Manual CAS# Latency = 4 RAS# to CAS# Delay = 4 RAS# PRE Time = 4 RAS# ACT Time = 12 Row Refresh Cycle Time (tRFC) = 60 All Else to Auto DRAM Static Read Control = Disabled DRAM Read Training = Disabled Mem.

Shut down, remove the stick and insert it in the third slot. Retest. Shut the system down insert a stick in first and third slot. Retest. Remove the DRAM and repeat with the other two sticks. Finally, test with all four. Results?
  7. Thanks Wired. More specifics is specifically a good thing. Specifically speaking that is :p:
