Heres my current state:

Settings:

CPU Core Voltage: 1.65v
DDR SDRAM Voltage: 2.6v
Chipset Voltage: 1.6v
AGP Voltage: 1.5v

PSU Actuals (fluctuations etc):

CPU: 1.63 to 1.64v
VCC Voltage: 2.64v
I/O Voltage: 3.28 to 3.34v
+5: 5.02 to 5.05v
+12: 11.97 to 12.03v
-12: 12.11 to 12.19
-5: 5.5v
3.3 Dual Voltage: 3.56 to 3.58v

I also noticed that the SATA Controller was enabled and SATA RAID ROM was enabled also - I take it it wont hurt to disable them (I use IDE)?

PCI Latency Timer: 32 Clock(s)

 

 
Research reveals the old RAM should have been running at 2.7volts...

We juuuust might be on to something here!
 
 

...

Nope.

I changed the voltage to 2.7 (the only increment the BIOS would allow) and I was able to play for 10 mins before it rebooted.  Hmm.  Rebooted - thats not happened before...

It was also on a continual reboot too.  It would get just past the Welcome screen and into Windows then reboot continuously.  So the voltage is now back down to 2.6...

Grrrr.  

have you updated your BIOS???

what was that you mentioned about a firewire port / drive connected to a usb header?
did you sort that out?

90% sure it wont be the problem but still if you know somethings wrong its best to cure it.

It was simply that Id "connected" a firewire lead into a 1394 socket.  The device wasnt powered so there shouldnt have been a problem.  Removed now and still, the problem persists.

Done.

Now for some gametime.

Thinking about using just the one stick again - if it works, its a workaround - but Id be pretty miffed as Ive just forked out £100+ on a new pair.

Bleedin pooters...  

Id go back down to one stick, it wont make that much difference in the short tearm, and itll help us identify the problem if that fixes it


...just to clarify..... the system was stable and good ? started having these problems, then you upgraded, and the problems are still there ?

 
Bugger. After the BIOS update, system crashes during gaming and reboots.

But, I finally get some sense out of Microsoft:

=========================
Error caused by a video device driver :shock:  :shock:  :shock:

Thank you for sending an error report to Microsoft.

Error report summary

Error type Windows stop error (A message appears on a blue screen with error code information)

Solution available? Yes

What does this error mean? You received this message because a device driver installed on your computer caused the Windows operating system to stop unexpectedly. This type of error is referred to as a "stop error." A stop error requires you to restart your computer.
 
Cause A video adapter device driver

Computer symptoms A message appears on a blue screen with error code information:

STOP 0x000000EA THREAD_STUCK_IN_DEVICE_DRIVER
- or -
STOP: 0x100000EA THREAD_STUCK_IN_DEVICE_DRIVER_M  

Action for you to take

We have analyzed your error report and there are two solutions for this problem for you to choose between.

+ Solution 1: Install the most current driver for your video card

yadda yadda...

+ Solution 2: Manually decrease Hardware Acceleration for your video adapter

This procedure prevents the display driver from programming the hardware incorrectly, but you may lose some display functionality and performance. Although you can increase the hardware acceleration settings higher than None to regain functionality and performance, these settings increase the chance that the issue will occur again. For maximum stability, leave hardware acceleration turned off.

Errr....  :shock:

+ Solution 1: Install the most current driver for your video card

Ive already done that...

So which driver out of the millions available shall I go with?...
