Re: System Crashing going to Blue Screen

Hi, My experience with BSODs more often than not involves memories. I have tried a couple of things aside from replacing the memory themselves: 1. Increase the virtual memory to roughly double physical memory; 2. Lower the CAS latency from 2T to 2.5 or even 3T; 3. install dual memory, instead of single 1G, 2 X 512; and/or 4. Run the BIOS at default and not Optimized settings. A couple of times, I have to reinstall the OS and used the drivers that were current at the time of the motherboard production (I know means not updated). There was even a time I had to tweak the registry to unload unused dlls and prevent certain services running at startup. Hopes this be of some help to you and give you ideas. Pls post again how things turn up. Good luck and kind regards.

Radeon hd6850 will work with Ga 945 gzm s2

Uses the Intel 945GZ motherboard chipset,

Brought out in the mid 2006.

PCI Express 1.1 technology came out in 2005;
PCI Express 2.0 technology came out in 2007,

Therefore the Gigabyte GA-945GZM-S2 uses the PCI Express 1.1 technology.

The Radeon HD6850 is based on the PCI Express 2.1 technology.

PCI Express 2.0 technology is backward compatible, with PCI Express 1.1 technology.

I have read problems on the internet, with graphics cards based on the PCI Express 2.1 technology, and being used on a motherboard with the PCI Express 1.1 technology.

I don't have any personal factual data, to support that statement with.
Just passing what I have read, on.

System Requirements -
550 Watt or greater power supply.

That is all
And now back to you Gort..................................

Nvidia nforce 680i sli 7F with no video.

The Nvidia GeForce 8800GTX graphics card, requires using TWO 6-pin PCI Express power cables,

MINIMUM power requirement for using TWO 8800GTX's is;

1) Using one 8800GTX requires a 450 Watt power supply.
Must have a 12 Volt power rail capable of 30 Amp's.
(If more than one 12 Volt power rail, add the amperage of all, to arrive at the total Amp's)

Using TWO in an SLI mode requires 750 Watts minimum, and around 50 Amps.

Let me ask a couple of questions;

1) Does your Power Supply have the minimum required Wattage, and Amperage on the 12 Volt power rail? (Or rails)

2) Are you using a Power Supply, that has FOUR 6-pin PCI Express power cables?

3) Looking at the adapter power cable, shown on the right side of the above link;

IF, your Power Supply does Not, have the recommended amount of 6-pin PCI Express power cables; did you use -> TWO 4-pin Peripheral power cables, for -> EACH adapter cable?

(Mistakenly referred to as a 'Molex' power cable. Molex was the first to design the connector. Name kind of stuck, like calling a adjustable open-end wrench, a Crescent wrench)

Why the line of questioning?

Computer unplugged from power, Anti-Static Precautions FOLLOWED, remove the power cables from the cards.

A) Is the connection end of either power cable burnt? (There should be FOUR cables) Look close.

B) Remove the cards from the PCI Express x16 slots.
Look down into the PCI Express x16 slots at the contact pins. (With a light)
How about the gold plated contact pins on the cards?

There HAS to be TWO 6-pin PCI Express power cables, for EACH card.
There HAS to be TWO 4-pin Peripheral power cables used for EACH 6-pin PCI Express adapter power cable.

A 6-pin PCI Express power cable requires TWO 12 Volt wires. (Yellow)
Using just one 4-pin Peripheral power cable will cause burning.
Not right away. Takes time.

Everything chilly? I'm 'barking up the wrong tree'?

Okay, now look at the capacitors on the motherboard.
To the left of the Processor socket are 6 solid Polymer capacitors.
If one of these babies is bad, YOU will know it. They explode.

More of a concern is to look at the other capacitors.
The Electrolytic Capacitors.
More specifically, they are Radial Aluminum Electrolytic Capacitors,

Visual signs of failure for bad Electrolytic Capacitors,

LOOK CLOSE. Use a light. A slightly bulged top, or a capacitor on a hard lean, may be hard to see if this is your first time.

Everything 5by?

Then your Power Supply cr@pped out.

Each PCI Express x16 slot is capable of providing 150 Watts.
Each 6-pin PCI Express power cable is capable of providing 75 Watts.

[ PCI Express;

Scroll down, read under the bold subheading - Power

A LOT of power is required for the two cards alone, and I do not even know what mobo, processor, ram memory, fans, optical drive/s, and harddrive/s, you are running.

Appreciate it if you would post back with your findings.
Post in a Comment.

New motherboard GA-p67x-ud3-b3 no video on boot

  1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
  2. 1 x PCI Express x16 slot, running at x8 (PCIEX8)
    * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
  3. 3 x PCI Express x1 slots
    (All PCI Express slots conform to PCI Express 2.0 standard.)
  4. 2 x PCI slots

I don't know how to plug in the wires for the ASUS a8n sli deluxe motherboard

Here is the manual for your motherboard (since describing a diagram probably isn't very useful...)

You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:

1) 24-pin power cable (from power supply)
2) 4-pin power cable (for CPU from power supply)
3) Any case fans with 3/4 pin connectors.
3) hard drives (SATA or IDE)
4) USB front panel ports
5) Audio front panel ports
6) Case plugs (power LED, hdd LED, power switch, and reset switch).

Will this video card run my motherboard

Yes it will.
Here are the requirements needed to run it
  • PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
  • 450 Watt or greater power supply with 75 Watt 6-pin PCI Express® power connector recommended (550 Watt and two 6-pin connectors for ATI CrossFireX™ technology in dual mode).
  • Your board has the Pci-ex16 slot and the Corsair has the power to run it.

    Okay, you don't need two video cards. Your 4 memory slots are grouped in two's. One set is black and blue, and the other set is black and blue also. These are your dual memory channels.

    The reason you can't see more than 2 gig ram is because you are probably not running 64 bit Windows with a 64 bit processor.

    32 bit windows will only display 2 gigs, but max memory is 4 gigs. It will draw on the extra 2 gigs if ever it is needed, but this does not happen very often, if ever.
