monsterbaldy Posted April 12, 2007 Share Posted April 12, 2007 Hey, I have a Conroe 6700, Asus P5B-E, and Twinx2048-6400 memory (xms2). I used to get TONS of random lockups using bios 1101 with all default settings, reboots, memtest x86 would fail out the wazoo. Sometimes when it would fail it would not even post again until I left it alone for a while... I am not doing any sort of overclocking and the temperature of the mb or cpu were never in "alarm" range. Then I tried to follow these forums and I did the following: Got the latest BIOS (1202). Loaded the setup defaults. Changed the voltage to 1.9v (used to be 1.8v) Changed the first 4 timings on the memory to 5-5-5-15. Changed the write to pre-charge delay from 10 - 15. It got MUCH better, but I still get a random restart or hang once in a while, just like before. Anything else I should be messing with? I read a very long and confusing thread about the P5B wifi edition and how people messed with the other memory settings, or changed the voltage to as high as 2.2, etc. I don't want to mess with any of that unless it is officially advised by corsair... but if I get desperate enough who knows. Also, is this type of memory problem limited to Corsair? Or is this Asus m/b having issues with all brands? There are certainly a lot of threads about issues with the P5B series... anyhow, that might be a better question for the assu form but thought I would ask. -ben Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 13, 2007 Corsair Employees Share Posted April 13, 2007 Run http://www.memtest.org with the Memory voltage set to 2.0v. Test each module one at a time. What is your full system specs? Link to comment Share on other sites More sharing options...
monsterbaldy Posted April 19, 2007 Author Share Posted April 19, 2007 My system specs are: ASUS P5B-E LGA 775 Intel P965 Express ATX Intel Motherboard - Retail SeaSonic S12-430 ATX12V 430W Power Supply - Retail CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model TWIN2X2048-6400 - Retail EVGA 256-P2-N624-AR GeForce 7900GS 256MB GDDR3 PCI Express x16 KO Video Card - Retail E6700 Conroe CPU 2.0V ran with no issues in memtest for 8 hours straight. The system was also highly stable UNTIL I ran World of Warcraft for the first time, where it crashed the normal way: The video signal is lost and the computer is unresponsive. I power it down and then power it on as much as I want and it won't even post. 15 minutes later it will. The m/b temperature never seems to go higher than 114F. The CPU never higher than 116F. Video card never even gets to what half of the slowdown threshhold listed in the properties is, though I can't remember exactly what it was. I don't know what to do anymore... Any suggestions are much appreciated. -ben Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 20, 2007 Corsair Employees Share Posted April 20, 2007 The PSU you have my not have enough power for your Video card you might check that, and if you are not getting errors in memtest that would suggest some other problem, but to be sure please load setup defaults in the Bios and then Change ‘Write to Precharge delay’ in the BIOS (same page as for latencies) from default 10 to 15 and then test the modules again with the Voltage set to 2.0 Volts and the tested settings set manually! Then test with http://www.memtest.org to be sure! Link to comment Share on other sites More sharing options...
monsterbaldy Posted April 20, 2007 Author Share Posted April 20, 2007 I am going to buy a 650w seasonic power supply, I will let you know how it goes. -ben Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 20, 2007 Corsair Employees Share Posted April 20, 2007 Yes please do and please make sure that you are setting the ‘Write to Precharge delay’ in the BIOS (same page as for latencies) from default 10 to 15 and then test the modules again with the Voltage set to 2.0 Volts and the tested settings set manually! Then test with http://www.memtest.org to be sure! Link to comment Share on other sites More sharing options...
monsterbaldy Posted April 22, 2007 Author Share Posted April 22, 2007 So I upgraded to a 550w Antec power supply. So far so good, but the problem was intermittent so I can't be sure yet. I am using all the tested settings, including voltage which was run at 1.9v for the test. Memtest and Prime95 had no problems, I think the PSU probably was underpowered. -ben Link to comment Share on other sites More sharing options...
monsterbaldy Posted April 22, 2007 Author Share Posted April 22, 2007 Ok it happened again. And as soon as I could get it to boot again I did memtest and got failures everywhere, at 1.9 or 2v. I don't want to deal with this anymore, I am going to go buy some new memory and see if that fixes it. I think that this board has trouble supplying a good steady higher than normal voltage to this memory for some reason. It's the only reason I can think of that sometimes this thing passes memtest totally clean, and othertimes fails everywhere. If the new memory fails I am going to cry... and then buy a new motherboard.... and then a cpu.... and then a video card... and then I will take a new loan out on my house. -ben Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted April 25, 2007 Corsair Employees Share Posted April 25, 2007 Wait; what was the error you got? Link to comment Share on other sites More sharing options...
monsterbaldy Posted April 30, 2007 Author Share Posted April 30, 2007 There was no error, the machine would just stop posting video or responding, and could not reboot, exactly the same as with the old power supply. Changing the power supply to a 550 watt Antec had no effect. I did go buy new memory, and the system has had no issues since I put the new memory in and that is the only thing I changed. To me this confirms that it was an issue with the memory. I would like to exchange it for another pair, can you advise me how to start this process? -ben Link to comment Share on other sites More sharing options...

monsterbaldy Posted May 6, 2007 Author Share Posted May 6, 2007 That form requires you to have an email client installed to submit the information. I use a web-based email client. Is there another form I can use? -ben Link to comment Share on other sites More sharing options...
monsterbaldy Posted May 7, 2007 Author Share Posted May 7, 2007 Nevermind, I used my work computer which had outlook. RMA form submitted. Link to comment Share on other sites More sharing options...
matt_chew6 Posted May 11, 2007 Share Posted May 11, 2007 Hey, this is my first post here. I had been searching the forums and found that I am having the same problem as you are with the exact same mobo and memory. I tried messing with the voltage, and many other bios settings. When I changed the DRAM frequency setting in the bios from 800 to 667, I have not had a problem since. I know this is not taking full advantage of the memory, but my system has not crashed since I changed this setting. Link to comment Share on other sites More sharing options...
