v2k Posted March 1, 2009 Share Posted March 1, 2009 I'm having the same issue. I've been testing with memtest86 3.5 I've tested each DIMM on its own in each of the 3 slots: DIMM_A1 DIMM_B1 DIMM_C1 As soon as I add another DIMM, memtest86 instant reboots at the start of testing. I've tried all combinations of slots; using primarily: DIMM_A1 DIMM_B1 With all 3 DIMMs, memtest hard locks the system at 7% of the first test. I tried knocking the DIMM bus voltage down to 1.6v, but it had no effect. When I had all 3 DIMMs in originally, I was seeing frequent BSODs in Windows7 64. What do I do?

DerekT Posted March 1, 2009 Share Posted March 1, 2009 Please download and follow my above instructions. Use the given Memtest86+ Version 2.11 and not the one you have. Link to comment Share on other sites More sharing options...
v2k Posted March 2, 2009 Author Share Posted March 2, 2009 Interesting. What's wrong with v3.5? I redid the test with 2.11 with all 3 DIMMs in and it passed. Here's my cpu-z: http://novuscom.net/~vjewlal/cpu-z.png Now I'm just waiting for the next bluescreen... haven't seen one yet, but it hasn't had much uptime.

DerekT Posted March 2, 2009 Share Posted March 2, 2009 3.5 is a different piece of software Memtest86 and has not been updated for quite some time. 2.11 is Memtest86+ and is still being updated. Your memory is running at i7 stock = 1066Mhz (533 DDR). Set as below and repost after memtest. Enter your BIOS and set to these values: AI Overclock Tweaker Ai Overclock Tuner = X.M.P. CPU Ratio Setting = 20 BCLK Frequency = 133 PCI-e Frequency = 100 DRAM Frequency = DDR2-1600 All Else to Auto Voltages CPU Voltage = Auto CPU Pll Voltage = Auto QPI/DRAM Voltage = 1.40v IOH Voltage = Auto IOH PCIe Voltage = Auto ICH Voltage = Auto ICH PCIe Voltage = Auto DRAM Bus Voltage = 1.66v Advanced -> CPU Configuration CPU Ratio Setting: 20 C1E Support: Enable Hardware Prefetch: Enable Adjacent Cache Line Prefetch: Enable Intel Virtualization Tech: Enable CPU TM Function: Enable Execute Disable Bit: Enable Intel HT Technology: Enable Active Processors: All A20M: Disable Intel C-State Technology: Enabled C-State = C1 Shut your system down, boot to the Memtest CD and allow for two full passes. Then, if stable, enter Windows and post screenshots of the CPU-z CPU, Memory and SPD tabs. Link to comment Share on other sites More sharing options...
v2k Posted March 3, 2009 Author Share Posted March 3, 2009 Thanks a lot for the detailed instructions DerekT. The memtest86 passes succeeded. I'd post cpu-z, but I'm no longer running Windows7. I'm on sabayon right now. It seems stable. I've tested some mkv videos and I tested WoW and TF2 each without issue. I'm guessing it was just a Windows7 issue. (admittedly, it was silly to test a new system on a beta OS) Link to comment Share on other sites More sharing options...
DerekT Posted March 3, 2009 Share Posted March 3, 2009 If memtest passes, then you don't need to post anything anyway. You're knowledgeable enough to know if it is working correcly or not. You're very welcome. :): Link to comment Share on other sites More sharing options...
