DX79SR Board not detecting EVGA GTX 680 Classified GPU on first ever boot!





Hi, I'm having trouble getting the Motherboard to recognize the GPU on its first ever boot. According to the box the MOBO is NVIDIA SLI ready, I cannot get to see BIOS due to motherboard not detecting GPU. I get the 2 beeps pause 2 beeps from the MOBO which means the GPU is not detected according to the sheet that comes with the MOBO. I have re-seated the GPU several times on the primary slot and have tried all other PCI express slots also. GPU's normal operation green light is on, GPU's fan is on. I do not have another GPU to rule out PCI express slot being damaged. Are there any known motherboard compatibility issues with this GPU? I read in one google search that some of the new graphic cards have a new UEFI-compatible VBIOS (GOP) and that this motherboard has a older version and does not detect it, is this true? What can I do? please help, thanks

Motherboard - Intel - DX79SR

GPU - 1x EVGA GTX 680 Classified

CPU - Intel Core i7-3930K Sandy Bridge-E 3.2GHz (3.8GHz Turbo)

Memory - 4x8GB G Skillz Ripjaws Z Series

PSU - Corsair AX860i 860W

Operating System - None-yet, trying to install Windows 8 64-BIT
thanks, to all of you for the replies, after much trial and error turns out the culprit was the PSU. Amazingly one of the modular plugs had a dead terminal and was not giving power thru the cord, I tried another one of them and boom, GPU read. Seems like GPU was receiving only half the power it needed to fully be operative. With one plug it did turn on and fan blew but it was not functional until the second plug gave the rest of the power. Rediculous lol Thanks all who replied, never even thought of trying another terminal until i started trying to do stupid random things. Now to send back this damn PSU lol

<https://exchange.nagios.org/directory/plugins/hardware/others/gpu-sensor-monitoring-plugin/details> hi there floriann software,

first of all, i would say that it is always a better idea to open up a new thread, instead of engaging in an old one.

apart from that, as the drive is recognized on other systems except for the xp one, then it comes to drivers. make sure you go to the mobo's website and update the drivers.
is the drive initialized as mbr. in case it is initialized as gpt, i would advise you to back up all the data and initialize it as mbr. win xp has some limitations on that: https://support.microsoft.com/en-us/kb/2581408

cheers,
d\_know\_wd :) thank you for taking interest in my post.

i have solved the problem.it was mistake from my own part.

i have disabled some of the hardware detection services before the update.

i have disabled the "device install service" on the windows service

renabling it and rebooting it solved the … this is duplicate of <https://devtalk.nvidia.com/default/topic/1071283/>

let’s continue in topic 1071283. stick with the 2500k but still use your lower end mid-range 5770. the gaming performance is not any better when one looks at them side by side http://www.anandtech.com/bench/product/288?vs=287 . when only 100mhz separates the two overclocking the 2500k makes up the negligible difference and can then be pushed up 1ghz more just on air. continue saving for a better card. the 6870 is still settling for mid range located smack dab in the center of mediocreville. wait for a 670 or 680 keplar series gpu's from nvidia or invest in the 7970. any of those cards with 3gb of vram is going to add a huge future proof cushion. buy a z68 http://www.techpowerup.com/161073/msi-s-entire-z68-(g3)-h61-(g3)-series-motherboard-supports-intel-s-22-nm-processors.html or http://www.gigabyte.com/press-center/news-page.aspx?nid=1048 which will support their newer pci 3.0 system requirements.after you have your next generation keplar or southern islands video cards like the 7970 it's time to save up for the ivy bridge upgrade along with the necessary bios revision. you are going to be saving $100 off the top by going for a 2500k instead of the 2600k that you can immediately apply to your stash for your better gfx card in the future. i would skip right over the 6970's, 580's and 90's and well anything except the newest cards. while your saving it also gives the newly released cards or processors time to show any bugs like sandy had. if you are thinking about overclocking like a science lab it is simply

enter bios via delete, f1 or whatever your default key is to enter "setup"/bios, click huge button that says overclocking, change the multiplier from 33 to 44 and then f10 to save and exit. OK, Problem fixed. If anyone else comes across this problem: I was able to install the new driver by using Intel's EXE version rather than the zip version and disconnecting from the inet. Everything went fine. have added psu to above post. (i added specs because i knew someone would ask. however i think it's a software issue.)

unlikely that it's the psu.

the current psu is a hx750i, and the previous psu was a hx650i. swapped over a year ago at least. this is a recent issue.


good, a lot of times this is the psu. but with an excellent unit, that's far less likely.

were you monitoring temperatures at the time? was there something specific you were doing similar in both times? really intermittent things can be hard to nail down. [@pawel.zabielowicz](/u/pawel.zabielowicz)

sta… i think it’s too early to think about h.266.

in any case if it will be supported then you need new hardware.
