Gigabyte GTX570 overclocked GV-N570OC-13I crashes!

OCCT is a bit on the heavy side and whilst will test you card well will create a lot of heat and stress.  If you do use it make sure you keep an eye on the temperatures.

[elysion]

so which one you recommend in stead, i don't want to fry the chip. 3DMark?
all running smooth so far under 2D with the new F2 BIOS from GGB Site, not tested 3D apps yet though...
the BIOS is factory pre-clocked at 780MHz with 1.0255V which is reported to be good.
still checking the power distribution and voltage draw of my house and room and possible separation line for my room only to have everything as it should to rule out any other problems.

thanks

Every card must pass OCCT test if it is ok. If I buy new card, and pay for it, I will not see what test I "can" or "cannot" use !? Frying chip is also impossibile if card is ok: fan will be at 100% and will cool down GPU in reason temperatures. So  use OCCT, FURMARK and any other test you can find: card must pass it. If card dont pass it is not good, then return card to shop ( of course you must have strong and stable power supply, OK motherboard and OK RAM)

I wasn't saying he couldn't use OCCT just to make sure he kept an eye on the temperatures whilst he was.

just found a possible issue with either my power distribution to my room or the psu.
the  mobo shows me in bios a too low 3.3v which should be around 31.-3.3 normally. i can read 2.89-2.912 and this is very bad. now checking both either the power coming to my room thus fixing a new direct line and also if the PSU had any damage (but its just 4 months old)...lets see

that also explains why my usb frequently not worked or booted up and why i had instant crashes as soon as i want to start a game or benchmark, so it sounds obvious, i hope the PSU still okay its a Coolermaster Silent Pro Gold 1000W Modular, quite nice..

The chances are the PSU is fine although of course any can turn faulty. I always run my system through a APC 1500 UPS unit which as well as acting as a backup power supply also conditions the incoming mains to make it perfect. If you can afford one I would highly recommend their use.

[elysion]

well it was the issue it turns out. i changed the PSU and the voltage went back to normal, i guess it needs the 3.3v for 3d apps as well.
i am using a UPS and a voltage current surge protector, both of them, that's why i cant explain the PSU failing if it would come from a power related thing. well running so far and looking good.

what BIOS should i know use, i tried the stock and the F2 from the website both running on benchmarks.
Thanks

I wouldn't change the BIOS unless you have a problem that an update might fix. Anyhow I am glad that you got to the bottom of the problem. Is your PSU not under warranty ?

[elysion]

thanks, it is under warranty, but i am out of warranyt coverage here, lets see what to do, thanks
I need the original BIOS, did not make a back up, where can i get it? thanks

[Dark Mantis]

It should be available on the website for download. Failing that PM runn3R and see if he can get hold of it for you.

[elysion]

its not available on the website, on the F2 version which runs on 1.037v. thanks

Now, your card is stable?

[elysion]

changed the PSU, card seems stable but then want to run 3DMark Vantage bench marked and it stopped, CPU and IOH voltage dropped, I assume i still have a big power / voltage problem in my room, the card seems fine though.
trying with the UPS today and remove the over under current protection adapter which i have between the pc and power wall socket.
that might have been an issue too but i doubt.
getting a direct line today to my room from the main breaker so i hope its sorted out today. thanks guys

[Dark Mantis]

Well let us know how you go and I am sorry for you out there in the Maldives struggling with your problem! I could always come and fix it for you...

[elysion]

hi mate. looking good so far. I assume it has to do with my cabling, the 24pin atx goes to two more extensions and when i directly connect it to the mobo its working. also i installed the ASUS AI Suite II which gives me incorrect readings from the mobo and it was a big mistake to install it, that why i was concerned but in fact there has not been a problem at all, my original PSU is also working and i have directly plugged it in in the new wall socket made last night, so this is also an issue and my PC goes through direct connection without any ups or over-voltage protector adapter between.
my bios shows all readings normal in regards to voltages.
you can still come to Maldives with a good deal ;-) UK market is no. 1 here. will report back if any more problem arises, cheers mate
