blarue09 Posted January 16, 2009 Share Posted January 16, 2009 Hi, I am having a bit of freezing problems in windows/windows start-up every now and then and I wonder if my ram is the problem. I have ran memtest86 for a couple hours and there were no errors other than 3 ECC correctable errors. As per Asus P5Q-PRO specifications: 4 x DIMM, max. 16GB, DDR2 1200 / 1066 / 800 / 667 MHz, non-ECC, un-buffered memory Dual channel memory architecture My Current computer Specifications: RAM: CM2X1024-5400C4 (2 twin packs) = 4Gb CPU-Z timings (set to Auto in BIOS): 5-5-5-15-2T @ 334.4 MHz Motherboard: Asus P5Q-PRO with latest BIOS update http://www.asus.com/products.aspx?l1=3&l2=11&l3=709&l4=0&model=2269&modelmenu=1 CPU: Intel Pentium D 830 Smithfield OS: Windows XP 32bit In the Qualified Vendor List (QVL) of compatible RAM in my ASUS manual it shows a few corsair 667 ddr2 that work with my motherboard but my modules in particular are not listed. I also checked on the Corsair memory configurator and you do not have my memory listed as compatible. Why is this? Is there a reason why other 667MHz ram will work but not mine? Should I be making any custom timing/voltage/frequency changes to the ram in the bios? Or should I be getting new ram that is on the ASUS QVL and listed on the Corsair Memory configurator? Please try to help me with this problem if you can thanks. Link to comment Share on other sites More sharing options...
DerekT Posted January 16, 2009 Share Posted January 16, 2009 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. OC Charger = Auto AI Transaction Booster = Disabled Relax Level = 9 CPU Voltage = Auto CPU PLL Voltage = Auto FSB Termination Voltage = Auto DRAM Voltage = 1.9v NB Voltage = 1.45v SB Voltage = Auto PCI-E SATA Voltage = Auto Loadline Calibration = Auto CPU Spread Spectrum = Disabled PCIE Spread Spectrum = Disabled Clock Over-Charging Voltage = Auto CPU GTL Volage Reference = Auto NB GTL Voltage Reference = Auto Legacy USB = Disabled Run Memtest for two full passes. 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? Link to comment Share on other sites More sharing options...
blarue09 Posted January 16, 2009 Author Share Posted January 16, 2009 are all these values safe for my components? 1.45V seems really high, could it harm anything such as my chipset, UBS ports, etc.? I read in the review of the P5Q PRO by xbitlabs.com, http://www.xbitlabs.com/articles/mainboards/display/asus-p5q-pro_7.html#sect1 under "overclocking", that: "Even replacing the original thermal interface with a more efficient organic silicon thermal compound didn’t help us push the NB voltage over 1.32V. As a result, we couldn’t reach stability at FSB speeds beyond 540MHz. Further MCH voltage increase resulted into chip overheating." I also forgot to mention I have: Corsair CMPSU-750TX power supply Evga Nvidia GeForce 6800 GS / 256mb / VGA Memory Clock - 1.0 GHz / VGA Core Clock - 425.3 MHz Also, I have a bootable cd of Memtest86 V3.4a, is V2.11 better?

DerekT Posted January 16, 2009 Share Posted January 16, 2009 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? Link to comment Share on other sites More sharing options...
blarue09 Posted January 31, 2009 Author Share Posted January 31, 2009 I had my computer fixed finally so I am now running on 2 modules (2GB). In my process of finding the source of the problem I ran memtest on all 4 modules of ram that i have individually. I tested the first one in all 4 slots and all passed fine with over 9 passes (overnight, during the day, etc.) one modules, however, failed testing. I tested it a second time just to be sure and it failed again. here are my results. http://i12.photobucket.com/albums/a201/blarue09/DSCF2345.jpg http://i12.photobucket.com/albums/a201/blarue09/DSCF2343.jpg can anyone help me figure out if i need to have this module warrantied or not?

DerekT Posted January 31, 2009 Share Posted January 31, 2009 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. Link to comment Share on other sites More sharing options...
dj_fly02 Posted February 8, 2017 Share Posted February 8, 2017 Hi I have a same problem with my memory i have 2 kit of 2 GB in total 8gb on my p5q pro with am intel procesor e8600 fsb 1333. The memory is corsair xms2 800mhz 4-4-4-12 could You help me to setup the bios to Work i specificate i have the Last bios instalez 2102 .
