KeyboardSamurai Posted February 7, 2008 Share Posted February 7, 2008 I'm running XP Pro 32 bit, and recently added a second set of TWIN2X1024-5400C4. My computer has started to crash occasionally while running high performance programs. BIOS is updated, I've memtested all the RAM in various configurations and had no errors. My settings are at default, and I'm thinking the standard looking "667 and up the voltage" might be in order, but haven't wanted to get ahead of myself and pick the wrong values. However, immediately following a crash, sometimes the computer won't restart for a few seconds, which makes me wonder about overheating. I've been monitoring all my temps. except RAM (which I don't have a monitor for). Removing either set of RAM seems to fix crashes, but they're random enough that I couldn't guarantee it's solved the problem. What do you think?

Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 I would set the memory Voltage to 2.0 Volts and set the NB/MCH/SPP Voltage to +.05 Volts and see if that helps and also look for the setting under memory timings "TRC" and set it to 24.

KeyboardSamurai Posted February 8, 2008 Author Share Posted February 8, 2008 I can do everything there except find the NB/MCH/SPP Voltage. The only Voltage Control I've been able to find was DRAM Chipset Core CPU Termination VCore I haven't been able to find anything in the manual about changing Northbridge voltage, nor have I been able to find anything about SPP or NForce SPP. I'm not sure if it's hidden in there somewhere, or just not an option. Any suggestions on how to find out, and if I can't change it, do you think it safe or advisable to follow through with the other settings without changing NB voltage?

DerekT Posted February 8, 2008 Share Posted February 8, 2008 What do you think? With that board, and attempting to run 4 X 1024MB strips of 5400's, you will have to drop the DRAM speed to 533Mhz. The issue is of the on motherboard memory controller not being able to keep up with four strips as it does with two strips and must needs have the bandwidth dropped. Test it out. Set your DRAM bandwidth to 533Mhz and the C4 timings. Set your DRAM voltage to 2.0v. See if you find stability. The issue of not restarting immediately is often that in such situations, the DRAM needs to release and discharge the energy before being ready to renew and begin.

Corsair Employees RAM GUY Posted February 8, 2008 Corsair Employees Share Posted February 8, 2008 And try upping the Chipset Voltage! Link to comment Share on other sites More sharing options...

KeyboardSamurai Posted February 9, 2008 Author Share Posted February 9, 2008 By upping chipset voltage, is setting this to 1.5 what you had in mind? I believe it's the NB voltage control. Correct me if I'm wrong. Link to comment Share on other sites More sharing options...
Xtreeme Posted February 9, 2008 Share Posted February 9, 2008 ya, NB is northbridge and its part of the chipset set. Chip set means both NB and SB or southbridge. Tech NB is the right one sinceit controls the mem. SB runs other stuff like usb, and other periphials. Link to comment Share on other sites More sharing options...
