Hi everybody,

I am trying now for days to find the right settings for my System. I am getting one bluescreen after another (on idle too)
Even on Bios defaults or Optimized Settings my System is crashing. I have read a couple overclocking guides, but I guess I don´t understand them completley. I never used to overclock my Systems so thats all new to me. If somebody has almost the same System like I do. I would like just to compare the Bios Settings to find out why I m gettin bluescreens.

My System :

Intel Core 2 Quad Q9450 (Yorkfield)
OCZ ReaperX HPC DDR3-1333 2 GB Kit (OCZ3RPX1333EB2GK)
Gigabyte GA-48T-DQ6 (Bios Version F6D)
EVGA Geforce 9800 GTX 512MB
Seagate 500GB (ST3500320AS)
Samsung 20x SH-S203S
Antec Nine Hundred Ultimate Gamer Case
OCZ 720 Watt EvoStream SLI (OCZ720EVOSLI)
Microsoft Vista Home 64-Bit (OEM)

Most likely cause for your issues is unstable RAM. Try going into BIOS and setting the DIMM voltage to 1.85V, and changing nothing else.

Hi,

I checked the DIMM Voltage with Everest Ultimate V5.0

it is already at 1.89V

or is there a better software to check the DIMM Voltage?

Don't READ it with SOFTWARE, SET it in BIOS.

Hi,

check the Bios. All I could find is DDR3 Over Voltage. I set it to +0.40
How come that the DIMM Voltage is not displayed in the Bios.

There is one strange thing I found out.

Everest and CPU-Z recognize my Memory as OCZ3RPX1333EB1G
I found the specs for that one:

Part number OCZ3RPX1333EB1G
Max bandwidth PC3-8500E (533 MHz)

Attributes
Number of banks 8
Nominal Voltage 1.50 Volts
EPP no
XMP no

Timings table
Frequency (MHz) 533 622 711
CAS# 6.0 7.0 8.0
RAS# to CAS# delay 5 6 7
RAS# Precharge 5 6 7
TRAS 20 24 27
TRC 27 32 36

but on the Memory itself ( on the sticker) it says OCZ3RPX1333EB2G

How do I check now the DIMM Voltage if it is not displayed in the Bios???

This is a pesky issue with Gigabyte boards, the only way you can really know the DIMM voltage is to check it with a voltmeter. But +0.40V should be fine, that should be 1.90V which is close enough to the rated 1.85V.

The RAM is DDR3-1066 with an overclock rating of DDR3-1333. That's why it requires more voltage.

After I changed the DIMM Voltage to +0.40 its still freezing and giving me blue screens.

I run Orthos and got this:

Using CPU #1
Beginning a continuous self-test to check your computer.
Press Stop to end this test.
Test 1, 4000 Lucas-Lehmer iterations of M19922945 using 1024K FFT length.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 0 minutes 50 seconds - 1 errors, 0 warnings.
Execution halted.

Any other idea??

Try downloading the bootable CD version of Memtest86, you might have a bad module.
