macabeach Posted January 31, 2006 Share Posted January 31, 2006 Hello Ram Guy, I just bought another set of twinx 1024 for my ASUS Premium SLI motherboard but from a different vender than my original set. When I installed the second set in the remaining slots (A2-B2), my computer will not boot. It beeps long beeps with pauses inbeteen and the monitor will not turn on. i dont know what could be the problem. My original ram is the same XMS3208 V1.2 the only diffence is the number below that which state 0551001-2 while the ones on my original configuration state 0532123-2. I dont know if this is the issue but they are both DDR400 XMS 3200XL. PLEASE HELP as I spent all night trying to figure this out with no sleep. Thank you, maca Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 31, 2006 Share Posted January 31, 2006 It is very likely that you have 2 different revisions of the PC3200XL. Mixing revisions will often cause you to be unstable or not boot. Can you please list the complete info from the memory labels on the 4 DIMMs? http://www.houseofhelp.com/forums/showthread.php?t=34307 Mike.

macabeach Posted January 31, 2006 Author Share Posted January 31, 2006 Hello, Yes, Slots (A1-B1) CMX512-3200XL XMS3208V1.2 LOT#0532123-2 Slots (A2-B2) CMX512-3200XL XMS3208V1.2 LOT#0551001-2 THANK YOU, MACA Link to comment Share on other sites More sharing options...
Yellowbeard Posted January 31, 2006 Share Posted January 31, 2006 Hmmm....I don't see any conflicting numbers but, I don't know enough about the specific revisions. RAM GUY will see this post tomorrow and hopefully he can help out. I assume that you have tested both sets seperately? Also, can you run Memtest on each individual module for 3-5 passes. It's tedious but, 1 weak module could cause problems too. Just curious, what bios version are you running and are you OCed at all? Also, are there any performance or turbo type settings you have enabled? Mike. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 31, 2006 Corsair Employees Share Posted January 31, 2006 Please test the modules one set at a time to be sure one is not failing and I would set the memory voltage to 2.85 Volts at DDR333 at 2T Command rate with 4 modules.

macabeach Posted January 31, 2006 Author Share Posted January 31, 2006 Ram Guy, thank you for replying but iam really new at testing this DDR ram stuff. How can I test these modules. All I know is that the current ones in slots A1-B1 work fine but after adding the second set, the computer will not boot. It just responds with longs beeps. You mean like adding only 1 of the new modules to the current set I have one at a time??? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 31, 2006 Corsair Employees Share Posted January 31, 2006 Remove the memory you have installed now and test the new modules. If they all pass. then try the modules in slots 2-4 and see if its the MB that has a problem. And you may need to get the latest beta bios if you have a new core CPU.

macabeach Posted February 1, 2006 Author Share Posted February 1, 2006 Hey guys, good news, I did what RAMGUY suggested, I installed the new modules first and see if my computer would boot, it did. Then after I installed my original set of modules in sets A2-B2 and the timings are at 2-2-2-5 with 2.75 voltage. Thanks to everyone on this forum for help and support especially RAMGUY, he really knows his stuff. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 1, 2006 Corsair Employees Share Posted February 1, 2006 You may have to set the memory Frequency at DDR333 and set the timings to a more relaxed setting with 4 modules like Cas 2.5-3-3-7 at 2t Command Rate at 2.85 Volts.

macabeach Posted February 1, 2006 Author Share Posted February 1, 2006 OK, Change from ddr400 to ddr333 because the more memory you lose some timing, and bump up the voltage to 2.85? CAS setting to 2.5 what are the other numbers representing 3-3-7??? Sorry, I am new to this. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 1, 2006 Corsair Employees Share Posted February 1, 2006 Resulting Frequency: 166MHz Memory Timings: Manual/User Define SDRAM CAS Latency: 2.5T SDRAM RAS to CAS Delay (tRCD): 3T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 7T Link to comment Share on other sites More sharing options...
macabeach Posted February 2, 2006 Author Share Posted February 2, 2006 I adjusted the timing to their new settings as Ramguy suggested 2.5-3-3-7 at 2.85. My only concern is that I could not connect to the internet after reformating my computer and my screen started to flicker and act funny last night. Not as the result of the voltage changes??? These are the proper timings for a computer that is not overclocked?? I have no idea how to overclock. I dont plan on doing it. Athlon 4000+ ASUS SLI Premium 7800GT RAPTOR 74X2 LIAN LI 7B 4FANS THANKS RAM GUY Link to comment Share on other sites More sharing options...
macabeach Posted February 3, 2006 Author Share Posted February 3, 2006 RAMGUY, BEFORE returning the product would you suggest I stay with 1gb running at 2-2-2-5 rather than having 4 slot of memory used which is not recommended. would the performance of 1 gb be better suited with my rig at 2-2-2-5??

Corsair Employees RAM GUY Posted February 3, 2006 Corsair Employees Share Posted February 3, 2006 That would sound more like a power problem. But yes 2 1.0 Gig modules would be best if you need 2.0 gig or one Twinx1024-3200XL for best performance. Link to comment Share on other sites More sharing options...
