Overclock Crashing?

[PurpleCodes]

So i recently got 3 gtx 1070's for mining at my house and im mining zcash but whenever i try to overclock it even the tiniest bit it crashes the computer. 

 

I have a EVGA superclocked gtx 1070 currently running stable at 1620 MHZ

you sure your gpu is seated correctly? also, have you installed the up-to-date drivers for your gpu?

I just posted mine as you said it but is the overclock just over the factory settings?

[knightslugger]

what are the GPUs, exactly.

Yes and yes i thought it was the PCIE riser that was causing it but i put one in the slot and it still crashed

Claymore's For eth and EWBF's for zCash

Whats your psu? Did you do a clean install prior to getting the gpus? Try the display driver uninstaller or whatever its called. 

[BubblyCharizard]

its probably a power delivery issue, you might need to tweak the PCI-e voltage and/or increase the power threshold to each card

where the hell are you gonna spend it?

 

anyway, claymore version what? ...not familiar with EWBF.

 

Also, no need to OC. in fact, drop your power limit to around 60-70%, crank the Memory speed.

Over kill PSU 750W where without overclock it runs at 400W ( i plan to add more gpu's) Yes a brand new clean install of everything windows 10 and new drivers ect  and what do you mean by uninstall display driver

Currently trying to mine Zcash so memory clock is not a big priority for me i want the core clock to increase but when i min ETH i do crank up the mem clock and it is stable

DDU, aka Display Driver Uninstaller. it's a program that removes every trace of a particular vendor's software and is always suggested to be performed in safe mode.

I want to see if its something else before going into safe mode I might also try to boot linux if it doesnt work

when i mine zcash, i drop the OC, the power limit, and crank the memory. i always see better rates tweeking memory over core speed.

But zcash is based off clock speed so why do you crank the memory core speed will increase the sols more than memory

Reinstalled Afterburner and now it works

not in my experience. How long  have you been doing this? ...GPU mining i mean.
