Im having serious issues with instability...
I have the following gear:
Asus GeForce 9600GT 512MB
Asus - Socket 775 - ATX nForce 650i (P5N-E SLI)
Corsair XMS2 4096MB DDR2 PC2-6400 800MHz (5-5-5-18) (2x2048MB) (TWIN2X4096-6400C5DHX)
Intel Core 2 Quad Q9300 2.5GHz / 1333MHz / 6MB - Socket 775
Microsoft Windows Vista Home Premium 64bit
OCZ StealthXStream PowerSupply (PSU) 600W - Silent 120mm
2x Samsung 500GB SATA II NCQ (7200RPM / 16MB Cache / SATA II)
Symptoms:
Blue Screen of Death (BSOD) more regulary (before it was on first start-up of the day).
Graphical failures as in pixles all over the screen. Totall Freezes which is similar to a BSOD but I have to hardboot manually without any error messages.
I did a voltage-check from Sandra benchmark:
CPU DC Line: 1.34V
Aux DC Linw 3.30V
+5V DC Line 4.87V
+12V DC Line 12.04V
-12V DC Line -16.80V
-5V DC Line -8.53V
Standby DC Line: 4.95V
Battery DC Line: 3.14V
These are the recorded error-messages:
0x0000003B system_service_exception
0x00000050 page_fault_in_nonpage_area
0x0000000A IRQ_not_equal_or_less
0x0000007E (no message here)
Tried solutions:
* Removed all dust, vacuumed the case and checked all slots for dust and rechecked the cables that they are firmely fixed.
* Changed graphic-card to a Geforce 8800GTX and it was stable for a full day. Then it was back to same "crashes". So I changed back to 9600GT.
* Changed Voltage from "auto" to:
NB: 1,4V
Memory Timings: 4-4-4-15 @ 2clocks
Mem Volt: 2,1V
* Changed memory to "black slots" only
* Deep-formatted HDD and reinstalled VISTA 64bit
* Plugged out the battery, waited 15 minutes and plugged it back in.
* Memory goes without errormessages on check from Vista-CD
* HDD goes without errormessages on HDD-check from Vista-CD
None of the changes above made my system any more stable.
Anyone have further suggestions?
