Problems with 780ti classy sli, need advice on reinstalling os?

post #1 of 2
Thread Starter 
hey there Ive recently been having random on/off issues with my 780ti classys. I have a feeling for some reason my video drivers plus registries are just thrashed. even been having weird inconsistent issues with newly installed gsync. Geforce_SLI_Profile_Tool has never worked every time i try to export profiles it says program stopped working. and when i try to disable sli or enable it my pc blue screens graphics driver fails sometimes recovers sometimes hardboots then when i check if it actually disabled or enabled sometimes it hasnt and sometimes it has. kind of an inconvenience considering some games need sli turned on or off. note that im running watercooled gpu + cpu loop so switch gpus around in pcie slots is not ideal. loop is an absolute pain to prime. so im seriously hoping this is a software issue. also classified voltage tool randomly decides pc to borderline freeze to the point i have to restart computer(even with minor voltage changes) slows right down to a 1990's computer crawl .

I am seriously considering a complete reinstall but i want to know how to do it 100 percent correctly and cleanly.

Ive backed up everything i want to keep on my other ssd.

questions i have before i proceed to reinstall os.

1. should i upgrade my asus motherboard to the latest bios first?
2. should i reflash my gpu's from the skyn3t bios back to the stock ln2 bios first?
3. should i reset my cpu overclocks/memory overclocks(XMP profile) back to stock?( clear cmos?)
4. will bitdefender file shredding windows.old folder delete it as clean as possible?
5. should i use my motherboard disc to install drivers or should i go to asus website and download latest drivers and put them on usb flash drive? also how come when i click on drivers in device manager and look for driver updates it says i have the recent drivers yet when i go to asus it shows updated drivers for the devices.? why are names of the motherboards updated device drivers labeled differently. :s
6. also can I use ez3flash to flash gpu bios while in windows or do i have to boot from the win98 dos bootable flash drive? because i recently flashed my gpus using ez3flash in windows. seemed to work okay power target in msi afterburner went from 115% to 300% and i think boost is disabled even though aida64 shows it running at 326mhz when not running heavy loads.
7. also does anybody know any tight memory timings for the gskill trident x 2400mz memory, im running xmp 2401mhz profile right now but i think on a single monitor thats overkill when im sure 1866 or 2133mhz would suffice and add more cpu overclock stability/overhead in the process. would of done it already but i have no idea how memory timings work.
8. sorry about all the questions just losing my mind trying to comprehend all this. software issues make canadaspy go something, something........

note im using windows 7 ultimate 64bit

The first thing you should do is return everything to stock speeds as that's most likely the source of your problem and reinstalling windows is unlikely to help this. Return your CPU, memory and GPU to stock speeds and volts - I would also reflash your GPU bios back to stock. If you can do this via a DOS boot pendrive then that's safer but windows tools also work, especially if you're prone to crashing. By far the worst thing that can happen is your computer crash halfway through a flirmware update as this can brick your card.

Also, rather than re-install your OS on top of your old one, I'd suggest you reformat the drive which you can do in the windows install, no need to shred the windows.old folder and no remnants hanging around.

1. May as well update your bios but won't matter if you it before or after
2. Yes, reset your GPU bios
3. Yes, reset your CPU/memory overclocks
4. Reformat instead, see note above
5. download all the latest motherboard chipset drivers from its website and put on pendrive BEFORE nuking your windows install. If your motherboard chipset is newer than your windows install disc you may not have ethernet drivers.
6. Do it from DOS if you can, safer
7. I've rarely found XMP profiles to work too well as even though the memory is rated for 2400MHz, it doesn't mean the CPU/mothebroard which drives it can actually handle it. Memory overclock isn't related to the number of monitors your have. Keep it on stock settings until you're sure everything is stable. There are plenty of overclock guides on OCN which will help you
