Ex58-Extreme Stability Issues

Re: Ex58-Extreme Stability Issues

what bios are you using?it could be a sleep/resume or something else thats causing it to crash,did you set qpi voltage to 1.3000/ram voltage to 1.66 and manual timings? cpu voltage on normal

At the moment I'm using the F9h bios which was the latest when last I looked, I do see that there's now a F9l and I will update to that first chance I get.

The qpi is currently set to 1.26 which you had indicated "1.26000 qpi should be fine to start with and see if it still crashes" in your message on the previous page so do you think I need to boost that to 1.30?

Ram voltage is currently set to 1.64, OCZ spec calls for 1.65 (not an available option) but I've spoken to OCZ by phone (I love talking to live people) and they say that either 1.64 or 1.66 is well within tolerance for the ram that I'm using. (OCZ3X1600LV6GK)

Thanks,

Re: Ex58-Extreme Stability Issues

its up to you you could try 1.26000 to start with if no luck try 1.30000,also i remember some other users using an ocz psu n they had crashing also,im not saying that this is the cause but its worth trying with another psu if you have a spare to try and eliminate it

Re: Ex58-Extreme Stability Issues

Sorry your post had been overlooked!

Can you please tell me your current issues again, give me your full settings and specs and I will advise back.

Thanks!

Thanks for getting back to me, I appreciate it!

My hardware consists of a Gigabyte Ex58-Extreme (using the latest F9h Bios), an Intel Boxed Core I7 950, an OCZ triple channel 6 GB memory kit (OCZ3X1600LV6GK), an XFX GTX 260, an OCZ 850watt PSU (OCZ850GXSSLI), a Pioneer SATA DVD burner, a Segate 7200.12 500gb and a Western Digital 1tb WD1001FALS in a Lian-Li PC-A6010 case running Windows <nobr style="font-weight: normal; font-size: 100%; color: rgb(0, 0, 255);" id="itxt_nobr_2_0">Vista</nobr> x64 Ultimate.

The problem is that at least once a week (sometimes more frequently) the system reboots for no reason, most of the time when it's idle although once in a while I'll actually be working on it. The only thing that's noted in the system log is that "The previous shutdown was unexpected".

I've had to deal with this type of thing in Windows XP and I have gone to the "Startup and Recovery" system settings screen and unchecked "Automatically restart" and there does not appear to be a blue screen with any type of stop error message when this happens.

As I'm sure you know the Bios has an incredible list of settings and options and here's a list of the most relevant:

CPU Clock Ration 23X
Intel Turbo Boost Enabled
CPU Cores Enabled All
CPU Multi-Threading Enabled
CPU Enhanced Halt C1E Enabled
C3/C6/C7 State Support Disabled
CPU Thermal Monitor Enabled
CPU EIST Function Enabled
Bi-Directional PROCHOT Enabled
Virtualization Technology Enabled
QPI Clock Ratio Auto
UnCore Clock Ratio Auto
Isochronous Support Enabled
Base Clock (BCLK) Control Enabled
BCLK Frequency 133
PCI Express Frequency Auto
C.I.A.2 Disabled
CPU Clock Drive 800mv
PCI Express Clock Drive 900mv
CPU Clock Skew 0ps
IOH Clock Skew 0ps
Performance Enhance Standard
System Memory Multiplier 12.0
Load Line Calibration Disabled
CPU VCore Normal / 1.1625
QPI / VTT Voltage 1.26
IOH Core Auto

All memory voltages and timings are manually set to OCZ specs for this memory.

If you look back at the previous page Wazza300 had said:

its not advised to use auto voltages as it usually overvolts components try setting them manually as this might be causing crashes even if its passing memtests,set your ram to its rated voltage,you can set cpu voltage to normal keep c1e enabled and it will lower volts at idle,and slightly raise qpi volts to accomodate your ram timings,1.26000 qpi should be fine to start with and see if it still crashes,also try re-installing your graphic <nobr style="font-weight: normal; font-size: 100%; color: rgb(0, 0, 255);" id="itxt_nobr_11_0">card</nobr> drivers as this might be causing it too

After making those changes and reinstalling (actually updating the video driver with NVidia's latest release) the video driver the system seems to be slightly more unstable than before and I've experienced multiple reboots on the same day. Although there have been times when it's run for a couple days without a reboot.

Well here is what I suggest you use for your hardware at stock >>


BSOD Error codes and what they mean:
0X00000050 << Incorrect Memory Timing/Freq or Uncore Multi
0X00000124 << Incorrect QPI/Vtt Voltage (To Much/Not Enough)
0X00000101 << Not enough Vcore Voltage
