M4rco Posted June 21, 2007 Share Posted June 21, 2007 Hi, since I didn't get any response via email (maybe there were some problems or anti-spam or whatever), I'm attaching the email describing my problem below Thanks ---------------------- Hi, I have the current system from March 2007, bought from one of your official resellers in Italy (DeepOverclock.com): Intel Core 2 Extreme QX6700 Asus Striker Extreme (BIOS rev. 1102) 2X1GB DDR2 PC6400 Corsair C3 XMS2 Dominator (TWIN2X2048-6400C3DF) Twintech GeForce 8800 GTX XT 768MB Corsair HX Modular PSU 620W Creative X-Fi Fatality Professional Series on Windows Vista Ultimate 64 bit After about 2 months from the purchase I had some problems with my system, it wasn't able to POST (no beeps). I tried to remove every board and test the system through various conditions, I obtained the following: - Only CPU: 1 long beep and 2 shorts (video card error) - CPU with just 1 module of ram (tried in every slot): no beeps. - CPU with 1 module and the video card: long beep (memory error). Then, after some cmos and power resets the system returned working again without any problems, so I left it as it was, thinking it would be ok. Well, it worked until now, then a couple of days ago I was getting a lot of BSODs and when I restarted the pc for the last time it wasn't able to POST giving me the long beep (memory error). So I tried removing the ram modules and, trying them one at time, I found that one of the 2 gave me the problem, because with the other, my system was POSTing correctly. Now here comes the strange part, I found the bios values that you suggest on your forums: AI Over Clock Tuner: Manual NOS: Disabled SLI Ready Memory: Disabled DDR2 SDRAM Clock: 800 MHz SDRAM CAS Latency: 3T SDRAM RAS to CAS Delay (tRCD): 4T SDRAM Row Precharge (tRP): 3T SDRAM Active to Precharge Delay (tRAS): 9T SDRAM Write Recovery Time: 5 Command Rate: 2T DDR2 SDRAM Voltage: 2.4 V (if I put something less with these settings, like 2.2 or 2.1, the system will not POST and gives me a long beep) USB Legacy: Disabled other settings are left to Auto/Default with these settings my system was booting up correctly with the 2 modules together, but gave me a lot of BSODs. So I tried memtest86+ on the 2 ram separately and it found a lot of errors for the module that was giving problems before, while the other one was error free. This until yesterday... I found that, with just the module that is working installed, the system seems to be stable if I use windows vista with normal "office stuff", but I'm having some BSODs while using some stress applications like games. So I tried memtest again and found that even that module is giving me a bunch of errors: - from 2 to 8 errors ONLY in tests 5 and 8 (not always in test 5 btw) in 3-4 passes of the utility. I always used the fan module that came with the memory. Now, I'm not sure if it's a fault in the ram or maybe something wrong in my motherboard? Any suggestion? Do you have some other bios settings that I may try on my motherboard while using memtest?? I just wanted to try some other tests while waiting for an answer from the reseller (deepoverclock.com). Thanks! Best Regards, Marco Calderan. --------------------------- BTW I just wanted to add the fact the with the module that seems to work correctly, the system is not able to post, even with relaxed settings, (5-5-5-12) if I set a voltage that is below 2.1 - 2.2, while the other module (the one that was giving a lot of errors) doesn't have this problem.
