Hopefully someone on this board can help me. I have a EVGA X58 SLI LE motherboard with the following hardware: Graphics: EVGA Geforece GTX-260 Memory: CORSAIR XMS3 6GB DDR3 SDRAM DDR3 1600 (PC3 12800) TR3X6G1600C7 G Processor: Intel Core i7 920 OS: Windows 7 64-bit I've been having problems with the computer randomly shutting down which has lead me to believe that I may have a voltage or memory setting improperly configured. Since I don't know anything about voltages, I've been using the BIOS defaults, but I'm not sure if they're correct. I'm not looking to overclock my board, I just want the best and most stable performance I can get. Here's what my BIOS settings say: Dummy O.C. - Disabled Extreme Cooling - Disabled CPU Clock Ratio - 20X CPU Host Frequency - Auto (Target CPU Freq = 2800Mhz (133x21) & Target Memory Frq = 1067 Mhz) MCH Strap- Auto CPU Uncore Freq - Auto CPU Clock Skew - 0ps Spread Spectrum - Disabled PCIC Frequency - 100 OC Rec - Disabled Turbo Performance - Disabled Voltage Control EVGA VDroop Control - With VDroop CPU Vcore - 0.9500V CPU VTT Voltage - +0mV CPU PLL Vcore - 1.800V QPI PLL Vcore - 1.100V DIMM Voltage - 1.500V DIMM DQ VREF - +0mV IOH Vcore - 1.100V IOH / ICH / I/O Voltage - 1.500V ICH Vcore - 1.100V Memory Settings Memory Speed - Standard Memory Control Setting - Enabled Memory Frequency - Auto (Target 1067 Mhz) Channel Interleave Set - 6 Way Rank Interleave Set - 4 Way Memory Low Gap - Auto tCL - 8 tRCD - 8 tRP - 8 tRAS - 20 tRFC - 59 Command Rate 1T tRRD - 4 tFAW - 20 tRTP - 4 tWR - 8 CH1 Round Trip Latency - 51 CH2 Round Trip Latency - 53 CH3 Round Trip Latency - 53 Back to Back CAS Delay - 0 tddwrtrd - 5 tdrwrtrd - 5 tsrwrtrd - 14 tddrdtwr - 10 tdrrdtwr - 10 tsrrdtwr - 10 tddrdtrd - 7 tdrrdtrd - 6 tsrtdtrd - 4 tddwrtwr - 7 tdrwrtwr - 7 tsrwrtwr - 4 trl - +0 Can someone please tell me what the settings should be? All of this stuff is greek to me. Tempest

[shock] .95 VCORE!!! [/shock] that just seems really low. every i7 i have started around 1.15 - 1.2v might try a bit more. IMO. EDIT: Although you'd think you'd get a 101 BSOD if it was vcore.

Definitely raise the Vcore to at least 1.15 or 1.2 with vdroop. Or try keeping it at .95 and switch to (without vdroop) see if that fixes your problems.

I tried raising the voltage and the computer wouldn't boot (it kept turning off during the BIOS splash screen). Is there something else I need to tweak when changing the CPU VCORE voltage? I didn't try it without VDroop yet however (what is that and do I need it?). On the PC Health screen there was on voltage (CPU VTT Voltage) which seems to go between 1.19V and 1.20V. I'm not sure if this is a big deal or not. Everything else was steady. Could it be a dying power supply? It's only a year old, but I suppose it could be going bad. Tempest

ok well you guys missed a very simple mistake. Your memory settings are way off. Here is the correct numbers DIMM Voltage - 1.650V Memory Frequency - Auto (Target 1067 Mhz) Change to a divider until and get as close to 1600 you can, a 12 divider should give 1596 so good enough tCL - 8 change to 7 tRCD - 8 change to 7 tRP - 8 change to 7 tRAS - 20 Manuely set to 20 try that.

Tempest Vdroop is how the voltage is delivered, i would keep it on, it provides more stable voltage to the cpu and is easier on the cpu, however there are people that are going to argue about it forever. I do not see what power supply you have but it is not the problem 9 of 10 times

Make those memory changes with the change in CPU VCore voltage or without? Tempest

Just don't touch the vdroop, leave it where it is. it should be green, red means its off (without)

Ok tried those settings and the computer wouldn't boot (or rather it turned off again). I tried combining those changes with the CPU VCore change and it still wouldn't boot. BTW while looking at the CPU VCore voltages I noticed that 1.4V - 1.59V were labeled green instead of gray (1.6V was red). Any significance to this? The DIMM Voltage of 1.650V was also green. Tempest

ok well i'm not sure why its turning off but the colors aren't really that important. Just don't use red and *most* of the time green is to high for 24/7 use but not always.

I did update to the latest BIOS. Are there any other settings of interest that I could post to help? BTW the power supply is an Antec 650W Earthwatts Tempest

I'm starting to wonder if the machine could be overheating. If so, could overheating be caused by incorrectly set voltages? My readings (using Speedfan) are: GPU: 42C Temp1: 66C (processor I assume) Temp2: 37C Temp3: 31C HD1: 33C HD0: 39C Temp1: 65C Core0: 79C Core1: 79C

I was reapplying the heatsink to my processor the other night and afterward when I was in the BIOS monitoring the temperatures I noticed that the VCORE was at 1.2 now on the Auto setting. I have no idea what I did, but it changed. Now when I set the voltages to the values suggested the system is stable an working fine. Odd, but I'll take it.
