mwahlert Posted June 12, 2005 Share Posted June 12, 2005 asus k8n4-e deluxe (latest bios revision) sempron 3100+ (1.8ghz 256 l2 90nm) 128mb pci-e x300 2 x 160gb hitachi 7200rpm 8mb sata -> raid 1 2 x 512mb corsair vs512mb400 783-0521049-0-614198 antec sp350 win xp pro sp2 blue screens of death and random locking are experienced with both sticks in. i have tried manually configuring the memory settings in the bios to no prevail. what really confuses me is that if i install either of the two modules by their lonesome windows will not boot AT ALL. instant blue screen. i ran memtest last night, overnight, with both modules installed and got loads of errors. i threw a POS ddr266 256mb stick of no-name i had lying around and the machine boots, and seems to run fine so far.

Garvin Posted June 12, 2005 Share Posted June 12, 2005 That Antec sp350 won't provide enough power for your system configuration: http://www.antec.com/specs/SP350_spe.html You might try swapping the two +12volt leads to see if this helps, one of the rails only has 10 amps the other 15 amps under ideal conditions.

Garvin Posted June 13, 2005 Share Posted June 13, 2005 Hmm, an nf4 chipset board, two 160gig SATA drives, a pci-e graphics card, onboard sound, one stick of ram vs. two sticks and a 10 amp rail, hmm. Hope Ram Guy has a bios solution for you. Good Luck. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 Please test the modules one at a time with http://www.memtest.org and I would set the Dim Voltage to 2.7 Volts as well. If you do find one failing then lets get it or them replaced. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However; if you get errors with both modules, that would suggest some other problem. And I would try testing the memory in another system to be sure. And I would agree that PSU may not have enough power to run your system. What would be important would be the max continuous power available and most 350 Watt PSU's would be about 200 Watts. With your configuration you would need to have almost 300 Watts Max continuous. Your CPU, Video Card, HDD's and Memory will max out the power wile in normal use and eventually that PSU will fail or cause other hardware to fail because of abnormal power and or bleed thru more than acceptable noise for the 110 AC conversions that takes place. If you have doubts I would encourage you to test the modules in a known working system to be sure. Link to comment Share on other sites More sharing options...
Garvin Posted June 13, 2005 Share Posted June 13, 2005 Looking at your K8n4-e motherboard manual and the warning about dimm/slot placement and failure to post; it looks like a single double sided stick should go in slot number three- two double sided sticks should go in slots one and three (slot one is the slot closest to the processor). There is also a warning about incompatibility with double sided x16 modules and 128 mb chips. I don't know what those sticks have on them; you'll probably have to wait for Ram Guy to pop in. There's also a warning about being sure to plug the four pin +12v connector to the board or post failure will occur. ps: Page 2-26 of your manual lists a 350 watt minimum power supply but when you read the components they tested with supposedly you can see its not with this board. Four 512meg sticks in a three slot board, hmmm. Asus frequently makes manual mistakes. I'd still try swapping the +12 rail connections around in case some components are trying to suck to much juice during post off of that 10 amp rail.

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 All of our XMS modules are made with By 8 memory IC's only. And as far as I know Value select DDR400 and DDR333 modules should all be made with By 8 IC's as well. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 Please test the modules one at a time with http://www.memtest.org and I would set the Dim Voltage to 2.7-2.8 Volts as well. And you might check the voltages in power management to make sure they are stable. Link to comment Share on other sites More sharing options...

And you might check the voltages in power management to make sure they are stable. how long of a test period is required? also, i just tried some more tinkering. the machine will post and load OS w/ either of the modules installed in slots 2 or 3. both display the same behavior in slot one, which is POST and OS blue screen immediatly.

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 Usually 2-3 passes would be enough to show a failing module, but if you get errors please note the test you get errors on. This will help to determine the failure. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 Please check the manual, they may have to be in a specific slot with only one module installed. And I would make sure that you have the latest bios as well, Version 1.005 dated 5/19 looks to be the latest. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 If they will run in slot 3 but not in slot one that would suggest maybe a bios issue and I would check with ASUS tech support to be sure. Also are you running Bios version 1.005? Link to comment Share on other sites More sharing options...

Also are you running Bios version 1.005? ok. i am now even more confused. i have completed three loops of memtest on each of the two sticks, both passed without hitch (in slot 3). i am at the latest revision 1005.

Corsair Employees RAM GUY Posted June 13, 2005 Corsair Employees Share Posted June 13, 2005 That would suggest either a bios issue with the CPU you have, or the CPU is failing and or the manual is in error. At any rate I would talk to the MB maker and see what they have to say. Link to comment Share on other sites More sharing options...
Garvin Posted June 14, 2005 Share Posted June 14, 2005 Could also be a bad slot on the motherboard. If both sticks pass Memtest in slot 3. Then slot 1 could be fubared especially if neither stick will work in slot 1. I'd RMA the board if that is the case. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 14, 2005 Corsair Employees Share Posted June 14, 2005 That may be true, but a call to the MB maker should be able to clear that question. Link to comment Share on other sites More sharing options...
mwahlert Posted June 15, 2005 Author Share Posted June 15, 2005 That may be true, but a call to the MB maker should be able to clear that question. What timings are reccomended for these modules? And at what voltage? I need to do some more testing before I RMA anything. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 15, 2005 Corsair Employees Share Posted June 15, 2005 I would suggest you let the MB set the timings By SPD but please follow the suggestion I gave previously to test the modules. Please test the modules one at a time with http://www.memtest.org and I would set the Dim Voltage to 2.7 Volts as well. If you do find one failing then lets get it or them replaced. Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it! However; if you get errors with both modules, that would suggest some other problem.

And I would try testing the memory in another system to be sure I did individually test the modules in slot three through 3 loops of memtest. No errors were indicated. I spoke with Asus the other day and they indicated the motherboard to be at fault. However, I again spoke with them today in regards to the possible power supply being the cause and they suggested I verify the proper timings for the memory.

Corsair Employees RAM GUY Posted June 16, 2005 Corsair Employees Share Posted June 16, 2005 You can use CPU-Z or Everest to see what's set in the SPD, but Value Select does not have published timimgs like our XMS modules do. But VSXXXMB400 would be either Cass 2.5-3-3-8 or Cass 2.5-4-4-8. Link to comment Share on other sites More sharing options...
