khildram Posted November 5, 2005 Share Posted November 5, 2005 Hi, I went trough a lot of posts on this forum, and I did not find an answer to my question, I need some help : Here is my configuration : MB: ABIT KX7-333 (VIA KT333 Chipset, latest AwardBIOS) CPU: Athlon XP 2200+ BIOS Settings : FSB 133MHz Ratio FSB:AGP:PCI 4:2:1 Multiplier Factor x13 Voltage : Auto RAM: 2x256MB of NONAME DDR PC2700 RAM. BIOS Settings : DRAM Freq 166MHz DRAM Clock : by SPD Timings : CAS 2.5 - Trp 3T - Tras 6T - Trcd 3T (slowest possible for that MB) Command drive strength: Auto DRAM Access 3T DRAM Queue Depth 4 level DRAM COmmand Rate 2T command DCCK Feedback Delay Auto I decided to go for more RAM so I bought 2x512MB of CORSAIR DDR PC2700 Value Select RAM (VS1GBKIT333) Since I installed those, I got W2K crashes, as well as random application crashes (firewall, antivirus, firefox, games, etc). I ran memtest86+ 1.60 for several runs in different layouts (each time I left it running all night from 22:00 to 09:00). 1. NONAME in DIMM1&2 ; CORSAIR in DIMM3&4 => errors in test8 2. CORSAIR in DIMM1&2 ; NONAME in DIMM3&4 => errors in test5 3.NONAME in DIMM 1&3 ; NONAME in DIMM2&4 => errors in test5 4. NONAME in DIMM1&2 => no errors 5. CORSAIR in DIMM1&2 => no errors I tested mixed 1&3 + 2&4 because I I saw that thread : http://www.houseofhelp.com/forums/showthread.php?t=37354 But I think that this is not a good setup as BIOS groups "Command drive strength" for DIMM1&2 / DIMM3&4 I also noticed that the NONAME have chips on one side of the SIMM while the CORSAIR have chips on both sides. Setting DRAM Clock and DRAM Timing to "by SPD" does not help My question is what can cause that problem. I do not have crashes if I use only NONAME or only CORSAIR. I read some people in this forum talking about Dual Channel activing/deactiving; how do we do that? What is it for? Thanks in advance for your help.
