Grinch80 Posted October 10, 2008 Share Posted October 10, 2008 I'm having the hardest time getting these sticks stable. I've memtested the hell out of them and they appear to be fine. But roughly 50% of the time, I hang at the end of the XP boot sequence. I'm running a Q6600 at 3.4 with the latest BIOS (1406). All stress tests come back clean (both CPU and memory, run independently), its just this weird boot problem I'm experiencing. My previous GSk 2x2GB memory had no issues. Here are my current settings. Anything I need to tweak? AI Overclock tuner: Manual CPU Ratio Setting: 8 FSB Strap to North Bridge: AUTO FSB Frequency: 425 PCI-E Frequency: 100 DRAM Frequency: 1066 DRAM CLK Skew on Channel A1: AUTO DRAM CLK Skew on Channel A2: AUTO DRAM CLK Skew on Channel B1: AUTO DRAM CLK Skew on Channel B2: AUTO DRAM Timing Control: Manual 1st Information: CAS# Latency: 5 DRAM RAS# to CAS# Delay: 5 DRAM RAS# Precharge: 5 DRAM RAS# Activate to Precharge: 15 All other memory timings: AUTO DRAM Static Read Control: Disabled DRAM Read Training: AUTO MEM.

Corsair Employees RAM GUY Posted October 10, 2008 Corsair Employees Share Posted October 10, 2008 Save your settings somewhere, and I would load the setup defaults, set the memory voltage to 2.1 volts and test them each one at a time to see if you can isolate a memory module that may be causing the booting issues. This should rule out your overclocking settings as a possible cause, and if you can isolate a memory module which consistently causes these issues then at least we will know where the problem lies.

Grinch80 Posted October 10, 2008 Author Share Posted October 10, 2008 Thanks for the response RAM GUY, I will test each stick individually. In the meantime, do you think I need more NB voltage? I'm at 1.26 (BIOS). I can't for the life of me find what the stock value is, so I'm a tad hesitant to push until I have some level of understanding. Do the DRAM CLK Skews do anything (I've never played with them)? The only other voltages which may apply to RAM are the NB GTL reference and NB Clock skew, but I've never played with these either as I don't fully understand what they do. Thanks again for the assist. Link to comment Share on other sites More sharing options...
Grinch80 Posted October 12, 2008 Author Share Posted October 12, 2008 FYI RAM GUY, both sticks are good, tested them individually. Also tested NB voltage...things seem to be stable with it set a 1.36. Anything lower, and I get the boot problems. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 13, 2008 Corsair Employees Share Posted October 13, 2008 You should be OK with the NB Voltage up to a max of about 1.45 Volts just no more than about .2 Volts over default usually. Link to comment Share on other sites More sharing options...
