superford Posted March 1, 2005 Share Posted March 1, 2005 I just purchased DDR CRSR 512MBX2 Kit VIS1GBkit400. Problem is i can get both to run in the 1 slot but cant get them to run together. I have tried slot 1-3, slot 1-2 slot 2-3. I have the Epox 8RDA3i motherboard. AMD 2800xp bartron cpu. Is there anything i need to do in bios before changing out memory. With the new memory in slots i can even get monitor to come on. I get a post error on motherboad C3 which on board is memory issue. Thanks.

CandyKid Posted March 1, 2005 Share Posted March 1, 2005 Welcome to the forums, superford! You might want to go into your BIOS and check out the memory settings... The CPU should be on a 166MHz/333FSB clock and the memory on an AMD rig should be 1 to 1 which means underclocking it to DDR2700 (for the best stability, I know it's sometimes not necessary). So, check out these settings... CPU External Frequency - 166MHz/333 Memory Interface - 100% Resulting Frequency - 166MHz/333 CAS Latency - 2.5 RAS to CAS Delay - 3 Row Precharge - 3 Cycle Time (tRAS) - 8 DDR Voltage - 2.65 Give that a whirl and see what happens. Also, try using only slots 1 & 2, instead of 1 & 3. PLUR CK Link to comment Share on other sites More sharing options...
superford Posted March 1, 2005 Author Share Posted March 1, 2005 ok i did all that. Still nothing. Should pc start up with 1 stick in any slot? It will start up with 1 stick in slot 1. It will not start up with 1 stick in slot 2 or 3. Thanks. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 1, 2005 Corsair Employees Share Posted March 1, 2005 That would suggest a problem with the MB. Link to comment Share on other sites More sharing options...
superford Posted March 1, 2005 Author Share Posted March 1, 2005 But it should start up in one of those other slots right? Is there any bios setting that will do something to those slots, that i am over looking? Thanks. Randy Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 1, 2005 Corsair Employees Share Posted March 1, 2005 Yes, you should be able to run one module in any slot. And if they both will run normally in slots one but not any other slots, I would have the MB checked. Link to comment Share on other sites More sharing options...
superford Posted March 1, 2005 Author Share Posted March 1, 2005 One other thing if you dont mind. On the package that came it shows it to be VS1GBKIT400. On the memory it shows VS512MB400. And at Corsair probuct page they have the kit and they have the singles. Just to make sure my 2 stcik would say 512 and not 1GBkit. What i am trying to do is make sure i didnt get a returned package and someone change out memory on me, Thanks again. Randy Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 2, 2005 Corsair Employees Share Posted March 2, 2005 That is correct, we use 2 VS512MB400 modules to make a VS1GBKit400. Link to comment Share on other sites More sharing options...
superford Posted March 2, 2005 Author Share Posted March 2, 2005 Thanks for the help. If you look in the motherboard section you can suggest a new motherboard for me. :D: Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 2, 2005 Corsair Employees Share Posted March 2, 2005 I'm sorry as I cannot suggest one MB maker over another. That just really causes a conflict of interest for me. Link to comment Share on other sites More sharing options...
superford Posted March 2, 2005 Author Share Posted March 2, 2005 Thanks any way. I put the 2 stick in my daughters pc and they worked fine. So i went and order the Abit NF7-S2 nforce2 ultra motherboad. Thanks, Randy Link to comment Share on other sites More sharing options...

superford Posted March 5, 2005 Author Share Posted March 5, 2005 Ok here is a update. Got new motherboard. Abit NF7-S2, When i put in both sticks of memory it will start up. Very unstable. With in 5 minutes i get the Blue screen with windows error. And a couple of times on start up after loading windows screen i get he blue screen with Sytem halted. The only way i can get it to run stable on windows and in games is to use one stick of memory and load fail safe settings in Bios. I turned up the ram voltage to 1.70 and still hasnt done anything. Spec. AMD 2800xp Barton, 500 watt psu, 12v@20a, PNY nvidia 6800 ultra, Windows ME. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 7, 2005 Corsair Employees Share Posted March 7, 2005 Please make sure that you set the memory Frequency at 100% or DDR333 so it is running in sync with your CPU. Then please test the modules with http://www.memtest.org. Link to comment Share on other sites More sharing options...
