Windows 7 - GTX260 Video Artifacting/BSODs

Windows tracks physical pages of memory using a table called the Page Frame Database. This database (which actually is just a big one-dimensional array) is indexed by physical page number. As a result, the page frame database is typically referred to as the Page Frame Number list or PFN. This ususaly accours for one ot two reasons, the first is being memory corruption. If their is a buggy driver in the system that is writing on memory that it doesn't own it could easily corrupt one of it's PFN lists or entires. So as suggested all ready try removing the nvida driver as explained and then reinatall it. Or you could just let windows install a driver and see if the issue still appears. Bad pool lits or header. Once again a driver issue. Just a thought you said you ran memtest have you tried it with one stick in at a time? Also try just using 1 stick after doing the driver reinastall. I would also like to have a look at what CPU-z lists as your memory and timings. Could you Copy and Paste screen shots of it on both sticks? CPUID Thanks. Fabe

Will try and run the memtest on each individual stick today as well. Should it put the single stick in slot 0? And how many passes do you recommend i do?

Your tRas is tighter than the XMP profile suggests 21 instead of 23. Try loosening that to match.

smartyeyeball is right I would follow his suggestion. Then as to which slot I would refer to the manual. It's been a while since I have done any memtesting but some Motherboards will recommend the slot some won't my DFI was the one closet to the edge of the board is how we explained it then.So I would see if they say if running only 1 stick place it in slot X. Times? 8- 10 passes. Seems like a lot but once again certain numbered calculations during one pass such as the 5th(if I remember correctly) in the sequence on memtest stresses the memory more than other calculations.Fabe

Changed the tRas to 23 now i will run the memtest for each individual stick and get back to you guys

Okay, ran both sticks of RAM through 10 passes of memtest each, and no errors. Just uninstalled and took out my nVidia 260, and running my on board ati 3300hd. Am going to update bios to F3 as well.

After troubleshooting with some friends, they seem to think its the power supply. What do you guys think about my 630watt rosewill? you think it actually puts out 630w continously? According to my GFX card it needs 550w. Would the psu be supplying enough?

The only true way to test a power supply would be to use the very expensive diagnostic equipment used in labs. But for us regular folks: I tested my power supply by hooking up my (analog) multimeter to the PCI-E dongles that I used to connect my GTX260 (I used a spare pair from the power supply while I was testing). I then observed the meter while I used the computer, first watching the voltage, then the amps, to see if there was any drop-off or erratic behavior while booting or using the computer. My reading were rock solid. So I declared my power supply good.

I spent uncountable hours trying to correct my TDR problem with bluescreen crash using a GTX260 after installing Windows 7 (TDR = Timeout Detection & Recovery = "Display Driver Stopped Responding and has Recovered"). It turns out that the video card was bad. The strange thing was that I was using it without problems in the same rig for 9 months with XP-SP3! After doing countless diagnostics I finally bought a new GeForce 9500GT card for $50 to use while I RMA'd the GTX260 back to EVGA. Installing the 'new' card ended all my video problems. When I got the replacement card back and installed it there were no problems. Both cards use the same nVidia Drivers.
So my advice is to not rule out a bad card. Ultimately that is what you may be dealing with.

Is this the PSU?

The 12v rails are getting close to a 260's max amp load draw, but it should be okay. (Amps are more important than wattage)

What 12v rail do you have your card connected to?

Just remember that normally the hardwired 4/8 pin CPU power and 24 pin motherboard power connectors are generally part of the 12v1 rail. Perhaps try connecting the card to to a different 12v rail to further 'evenly distribute' the load. ie connect the card to 12v2, 12v3 etc

If memtest with the correct timings / voltages are passing okay, and the power distribution is even - then unfortunately you could indeed be looking at a faulty card after all.

Thats my PSU

Thats my GFX Card

Just looked and my card is connected to the only PCI-e connectors that are on my PSU. Two connectors one is a 6-pin and one is an 8-pin where 2 pins can come apart so i can use just the 6-pin. So 2 6-pin connectors.

My vid card did come with an adapter, but according to the instructions in the video card box, they gave me the wrong adapter. They gave me a Dual 6-pin PCIe to 8-pin PCIe power adapter that the instructions say to use on a GTX 280 or 295. I apparently could try a dual 4-pin peripheral to 6-pin PCIe power adapter if i had one, correct? I'll see if my buddy has one or if i can pick one up in town.
