GA-Z68M-D2H and GTX 560 Ti 448 [PROBLEM]

[MrFu709]

 Hey guys. I just built my wife a new computer (long overdue) so she can continue gaming with me. Here are the parts:

Intel Core i5 2400 Sandy Bridge
GA-Z68M-D2H mobo
G.skill Ripjaws X Series (2 x 4gb)
EVGA GTX 560 Ti 448 Cores
SilverStone Strider Plus 500w PSU

Almost everything works great... Processor is surprisingly fast at default clock, ram runs at 2133 no problem, Windows 7 installed without issue...

But for SOME reason the motherboard will not acknowledge the graphics card as anything other than just a "standard vga adapter"... It's driving me nuts. I've swapped virtually everything in the system out with what I am running in my rig, and the ONLY combo that doesn't work is the gigabyte mobo with the evga card. It's the weirdest thing. I toss in my old GTX 285, it runs no problem, recognizes it and installs drivers right away. I toss in a 9600 GT, runs fine. I put the GTX 560 in, and it goes back to just thinking it's the standard adapter.

So I start to think maybe the card itself is jacked up... So I throw it in my rig with an old Core 2 duo E8400, XFX 680i tri-sli mobo, 4 gigs of ram, 1000w OCZ PSU, and it recognizes it right away and functions perfectly normally... The card is fine... Infact, I'm running it in my system right now, and have had NO issues.

So then I start thinking maybe (for some reason) the PSU I got my wife is messed up. So I tear apart my system, throw my 1000w in my wife's system with the GTX 560.... doesn't recognize...  I then throw my wife's SilverStone PSU into MY system with MY GTX 285... no problems.... Then the GTX 560.... no problems...

Something is SERIOUSLY driving me insane, I spent literally the entire day on this, with everything in every combination, and that posted build at the top is the only one what will not run correctly. Am I missing something? I couldn't find anyone else with compatibility issues online - infact, that same build is quite common and everyone has had positive feedback.

I also flashed the latest bios, F5, to no avail. I am open to ANYONE who can shed some light into this issue... If I was retarded and somehow overlooked something, please don't hesitate to make fun of me, but for the love of god, help me get my wife's computer to work for her...

Hi and welcome.

The first thing to try is to clear the CMOS. Please follow these instructions EXACTLY.

Remove the power cable from the mains supply and then press the power switch on the case for a few seconds just to drain any residual energy in the PSU capacitors.

Once done remove the motherboard battery for at least one hour before replacing it.
 
Next plug back into the mains supply and boot.
 
You will now need to enter the BIOS by pressing DEL and load Optimised BIOS Defaults.

Make any other changes to the BIOS settings to suit your self like disabling the floppy drive, disabling the full screen logo and making the HDD the primary boot device and then press F10 to save and exit.

Also make sure that you remove any traces of the old drivers  by using something like Driver Sweeper

Hi,
   Power Requirements for EVGA 560 448

Minimum of a 550watt power supply.

(Minimum recommended power supply with +12 Volt current rating of 38 Amps.)

An available 6-pin PCI-E power connector and an available 8 pin PCI-E power connector

Hi Carvetii,

I would say a PSU of at least 650w possibly more....have a read through these links and see what you think.

I followed the CMOS reset instructions exactly, no change in the situation. 

Also, it's not the PSU, as stated in the OP:

"So then I start thinking maybe (for some reason) the PSU I got my wife is messed up. So I tear apart my system, throw my 1000w in my wife's system with the GTX 560.... doesn't recognize...  I then throw my wife's SilverStone PSU into MY system with MY GTX 285... no problems.... Then the GTX 560.... no problems..."

That pretty much rules that possibility out...

Hi MrFu709,

What are the graphics BIOS settings for the motherboard and do you have the latest drivers from the EVGA website for that graphics card?

PCI-e slot is running at the standard 100 clock, onboard graphics are set to disable if discrete card is used (onboard chip DOES disable since it sees the card, it just won't recognize it as anything other than a generic, no-name card).

I can't load the drivers because the computer refuses to see it as needing drivers. It uses the most basic vga drivers that are standard to ALL graphics adapters.

My last option is to flash the bios to a previous version.... *fingers crossed*!!!

Have you got the latest version of the firmware on the graphics card ?

Make sure if you flash the BIOS on the motherboard that you don't use @BIOS for that. It is fine for the GPU but not the mobo. Use QFlash as it is much safer and less likely to brick your mobo.
