terror_adagio Posted April 26, 2005 Share Posted April 26, 2005 Hello, Following system: Intel P4 3.2C Northwood P4C800 Deluxe 1GB Corsair TWINX-CMX1024-3200C2PT No overclocking. Computer will not boot to Windows with the rated timings: 2-3-3-6. Only way I can get into Windows is with 2.5-3-3-6.... Attempted increasing DDR voltage to 2.6, no dice. Bad ram?

SpDFrek Posted April 26, 2005 Share Posted April 26, 2005 I would suggest raising the voltage to 2.75 for that board. You can also run Memtest86+ to check the memory for errors. If you get any you can test the memory sticks one at a time. That way you can narrow down the problems to one stick or the other. Link to comment Share on other sites More sharing options...
terror_adagio Posted April 26, 2005 Author Share Posted April 26, 2005 I tried 2.75 and it still did not work. Link to comment Share on other sites More sharing options...
SpDFrek Posted April 26, 2005 Share Posted April 26, 2005 If the modules do not pass Memtest @ 2.75 vDIMM then you need to RMA the modules. Please go to the warranty section of the forum to get warranty information. Link to comment Share on other sites More sharing options...
terror_adagio Posted April 26, 2005 Author Share Posted April 26, 2005 The thing is... I can't even get past the first black screen with it set at CAS 2 for it to boot from the CD to run memtest. Link to comment Share on other sites More sharing options...
Yellowbeard Posted April 26, 2005 Share Posted April 26, 2005 Try Memtest at 2.5,3,3,6 since the system will boot there. If you have a defective module, it will likely show up immediately even at CAS2.5 . Mike. Link to comment Share on other sites More sharing options...
terror_adagio Posted April 27, 2005 Author Share Posted April 27, 2005 2.5-3-3-6 will boot, but the RAM will not at CAS2. I don't want RAM that is not doing what its rated. Link to comment Share on other sites More sharing options...

I suggested this for testing purposes. I would not expect you to compromise what you paid for. However, there is no guarantee that the RAM is at fault. So, if you can get Memtest to run and test the RAM, that is a the best first step to solving the problem. Link to comment Share on other sites More sharing options...
terror_adagio Posted April 27, 2005 Author Share Posted April 27, 2005 Thats the thing I cannot get into memtest with it set at CAS 2, it won't get to that point. Link to comment Share on other sites More sharing options...
Yellowbeard Posted April 27, 2005 Share Posted April 27, 2005 Thats the thing I cannot get into memtest with it set at CAS 2, it won't get to that point. I understood that from above. See if it will pass Memtest at 2.5,3,3,6. Keep in mind this is for investigative purposes only. IF the modules fail at that speed then you have your answer. If they do not fail at 2.5,3,3,6 then you can most likely eliminate the RAM as the culprit. Bad modules will most often fail at either of those settings. Keep in mind that you have to disable Legacy USB Support in the bios to get Memtest to run with these ASUS MOBOs. Also, set the RAM voltage to 2.75v. Make sure your Memory Turbo is at AUTO, not enabled. Link to comment Share on other sites More sharing options...
terror_adagio Posted April 27, 2005 Author Share Posted April 27, 2005 If I disable USB legacy support... then I won't be able to use my keyboard, mouse, or external hard drive. What else could it be if its not the RAM that won't let it run CAS 2? Link to comment Share on other sites More sharing options...

What else could it be if its not the RAM that won't let it run CAS 2? USB keyboards and mice work just fine in the bios with legacy USB disabled. And, you will only need to disable legacy USB while using Memtest. You won't need your external HD while testing memory. You can turn it back on after the test. There are literally dozens of things other than the RAM that can cause problems. Incorrect bios settings, a weak PSU, a bad MOBO, a bad CPU, etc can do this. However, I don't want to speculate until we can eliminate some variables. The easiest way to eliminate the RAM is to run Memtest at 2.5,3,3,6 and at the other settings I listed above. Is there some reason you won't/can't run Memtest with the RAM at 2.5,3,3,6 with Legacy USB Support disabled? Mike. Link to comment Share on other sites More sharing options...
