I'm having a few probs with my system and have tried a number of fixes that I've seen on these boards to no avail. The support here seems amazing, though, so I thought I'd see if someone could help! When I first put the system together, I turned off legacy USB and left all the other bios settings alone. The RAM is recognized at 5-5-5-18-2T with Bank Cycle Time (Trc) of 23. I then ran memtest for 21 passes with no errors. I installed XP and the system ran fine for a few days. I wanted to exploit the RAM's EPP capability and I thought my mobo would support the EPP settings in the RAM but I couldn't figure it out :(: ...does this mobo actually support the EPP settings or did I get that wrong? I disabled AI OC and manually set the timings to 4-4-4-12 and voltage to 2.1v with all other settings remaining the same. The system fails immediately upon booting to XP. Sometimes I'll get a message about a program crashing (usually MS Update) but other times it will reset with no message. I then set the vdimm voltage to 2.0. The system seems a little more stable and will boot to XP but I get all sorts of crashes and random resets...sometimes a minute after logging in and other times after 3 minutes of browsing in Explorer or IE. The system won't stay up for more than about 5 minutes in XP, though. I checked the Asus website for bios updates but my bios is version 0404 and the latest on the website is 0307 so I'm guessing that I've got the most recent. I installed Asus PC Probe II and seem to be getting normal values but CPU-Z doesn't report the same thing for Vcore. I've attached a few captures of the CPU-Z screens along with PC Probe II. CPU-Z reports vcore fluctuating around 1.120v, sometimes going down to ~1.08v. PC Probe seems much more steady at 1.30v, sometimes dropping to 1.28v. AMD recommends 1.20-1.25v for these chips so I tried setting the vcore in the bios but no change is reflected in the values that CPU-Z or PC Probe report. I did some searching and found that there are software updates from AMD and Microsoft for dual core chips, so I installed amdcpusetup.exe, TscSync.zip, and WinXPdualcorehotfix.exe. These seem to have helped very minimally, if at all. One odd side note is that CPU-Z recognizes the EPP settings in the RAM as 4-4-4-12-22-2T, but when I set the timings manually and left all of the advanced settings at Auto, the system sets Trc to 23. I went in to the Advanced settings and put Trc to 23 but the stability was not affected...the computer was still crashing very often. I've got an idea or two left to try but I'm nearly out of options...Anyone have any suggestions? If I've left out some info, please let me know and I'll post any additional screenshots, settings, etc. Thanks a ton! :cool: Travis Link to comment Share on other sites More sharing options...
