Vista 64 bit blue screen at OS install


Recommended Posts


Got a problem with my Corsair modules and Vista 64 (probably). Have just built 2 identical systems.


Trying to install Vista 64 bit and gets a blue screen before install screen appears....:sigh!:


Went to bios, unlinked and gave it 1.90v...voila install begins and reaches the first reboot...blue screen:evil:


Trying to tweak bios setting with no result (many hours and reboots) then simply yank one memory modul out and installing Vista works like a charm.


Vista update and all drivers and utilities installed.... Installing memory module 2, start computer, blue screen before login screen.

Memtest86+ for several passes "no errors" with 2 x 2Gb.


This behavior is also identical for machine no 2:[pouts:

So... any suggestions?

How many DRAM sticks are you populating in these machines? It sounds as though you are trying to run with 4 sticks.


When populating with four DRAM slots it is advised to lower the DRAM speed by one bin and raise the MCH (Northbridge - Intel) or SPP/MCP (AMD) to +.2v in order to attain system stability.


Please research this thread:

Test with Memtest and OCCT.

Download memtest from--->

and extract the ISO image. Burn the ISO image to an CD-ROM disk.

Download Core Temp

Download OCCT

Download CPU-z from

Extreme Tweaker

CPU Level Up = Disabled

Memory Level Up = Disabled


AI Overclock Tuner = Manual

FSB (QDR) = 1333

MEM (DDR) = 1333

LDT Frequency = 5X

PCIE BUS, Slot 1 & 2, Mhz = 100

PCIE BUS, Slot 3, Mhz = 100

SPP <--> Ref Clock, Mhz = 200

Run Memtest for two full passes, then (If Stable), enter Windows and post screenshots of CPU-z's CPU, Memory and SPD tabs. Run OCCT and enter the settings button, set the monitoring to "Built In" and choose 70C as the max CPU temp. Let OCCT Run for the one hour. Please post a screenshot of Core Temp when OCCT has run for ~20 minutes.

Instructions followed to the letter, and.... it works:laughing:

Pictures as requested.

Going to install Crysis and put some pressure on the machine.

Thanks DerekT, if you have some more tweaking in mind I'm open to suggestions:biggrin:
