jstarman Posted March 13, 2005 Share Posted March 13, 2005 I have an Asus A8V Deluxe board, A64 3200+ CPU and 2 sticks of Corsair Value Select (2*512) Cas 2.5. I keep failing test 6 at 000374cccec - 884.7mb. It may take 1 pass or up to 19 passes before I will get 1 error at this address no matter what setting I use. I am using 2.5-3-3-8 1T 2.7V. However, I can pass Prime 95 for 24 hours without any errors. I've tried running it at default settings, small underclocking & small over clocling the memory with the same results (in some cases, it just takes longer to get the error). There have been some errors at failing address 00025d008ec - 605.mb but most of the time, it fails at the above listed address. I have tried literally over 25 different settings over the past 2 weeks trying to get an error free test. There have been 1 or 2 times where the same address failed at test 4 or test 7 once but other than those 2 or 3 times, the failures are on test 6. Do I have bad memory? Any suggestions? Thanks in advance for any assistance. Jstar Link to comment Share on other sites More sharing options...
Wired Posted March 13, 2005 Share Posted March 13, 2005 Tried one stick at a time in each slot? Link to comment Share on other sites More sharing options...
jstarman Posted March 13, 2005 Author Share Posted March 13, 2005 Tried one stick at a time in each slot? No did not try 1 stick at a time. Someone suggested that I run test #5 100 passes & test #6 100 times. Test 5 no errors. Test 6 2 errors at 000374cccec - 884.7mb. Same failing address. Should I have posted this in Warranty Questions section? If so, I will repost there. Link to comment Share on other sites More sharing options...
Wired Posted March 14, 2005 Share Posted March 14, 2005 Test one stick at a time in each slot, standard test. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 14, 2005 Corsair Employees Share Posted March 14, 2005 I would tend to agree with Wired ( :eek: ), what you have posted would suggest a power problem. Link to comment Share on other sites More sharing options...
jstarman Posted March 14, 2005 Author Share Posted March 14, 2005 I would tend to agree with Wired ( :eek: ), what you have posted would suggest a power problem. I ran memtest on each memory module separately in DIMM B1 as per the motherboard user guide for single channel. Used the same settings as above 2.5-3-3-8 1T 2.7V. Ran 10 passes of test 1-8 & then 50 passes of test 6 with each module. NO ERRORS. Man I have no clue. So I swapped places... stick 1 in DIMM B1 and stick 2 in DIMM A1 and 45 passes of all 8 tests. Had an error in test 7 on pass 2 @ 00028b73314 - 651.mb. So far after 46 passes it found 2 more errors at the same spot for a total of 3 errors. What would cause me to get that 1 consistent error when running the 2 modules together in dual channel mode? What do you mean a "power problem? My power supply? Or increase/decrease voltage to cpu and or memory. I'm using a Nexus NX-3500 350 Watt Quiet Power Supply. What is my next corse of action as I have no clue where to go from here and I'm assuming that my system is not stable due to these memtest errors. Thanks for any assistance!

Corsair Employees RAM GUY Posted March 14, 2005 Corsair Employees Share Posted March 14, 2005 You should really be using a 450 Watt PSU with this MB especially if you have a newer Graphics card ATI 9700/NVIDIA5900 or newer. And the errors you are getting at not consistent. If you have a failing module they would fail at the same address on every pass usually on test 5. Getting the errors like you stated 2-3 errors every several pass on test 5, 6, or 7 would suggest some other issue and the most likely cause of the type of errors you report would be a weak or noisy PSU.

jstarman Posted March 14, 2005 Author Share Posted March 14, 2005 I'm still not clear why the errors occur at the same exact address. Doesn't that suggest a bad spot on the memory? BTW, I'm using an older video card Nvidia MX-440 and only a floppy drive, dvd/cd-rw and 120 gig HD. Any other suggestions to try? This is a brand new system with the execption of the video card and i'm assuming it's not stable due to the memtest errors? correct? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 14, 2005 Corsair Employees Share Posted March 14, 2005 If you had a bad module you would be getting erors on test 4 on every pass. I'm still not clear why the errors occur at the same exact address. Doesn't that suggest a bad spot on the memory? Can a friend maybe help you test the modules in another system?

Can a friend maybe help you test the modules in another system? I would have done that already, but everyone i know (local) has an older system :(. Can you suggest other settings to try besides the 2.5-3-8-8 1T 2.7v? Thanks! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 14, 2005 Corsair Employees Share Posted March 14, 2005 I would set the command rate to auto or 2T and set the Dim Voltage to 2.8 Volts. Link to comment Share on other sites More sharing options...
jstarman Posted March 17, 2005 Author Share Posted March 17, 2005 I would set the command rate to auto or 2T and set the Dim Voltage to 2.8 Volts. I set the Vdimm to 2.6 since the same errors occurred with Vdimm at 2.7 & 2.8 and ran Memtest for 28 hours and 105 passes of test 1-8...No ERRORS! Problem solved but who would have thought it was caused by too much voltage. Link to comment Share on other sites More sharing options...
