gtx 780 classy voltage

[misfitkid86]

hi all! just curious whether 1.3v is too much voltage for the card? it's water cooled with an ek block and under the load of things like 3dmark and unigine valley my max temp is 55, so what should i do if anything? thanks!

1.30v under water is fine at 55c. what core speeds are you getting... 1400mhz?

keep going with the voltage and core frequency until your at about 62-65c max after looping unigine valley/heaven for about 30 minutes. raise the pwm if your having trouble getting higher vcore. leave the memory alone, though valley likes memory overclocks, it doesn't do much for gaming unless your on triple monitors.

Water Block should be ok though it is still a bit high for my liking. What is the frequencies of GPU... also Memory if you tweaked it? Oh and you have the custom Power Limit?

so i'm 1253 on the core and 1677 on the memory, i have not bios tweaked the card and am not using classy controller i'm just using the latest version of precisionx16. what pwm? as in the fans on my loop?

well i dont think your at 1.30v if your not using the classy controller and especially if your on the stock bios. you should be limited to 1.212v. use msi afterburner instead of precision. use afterburner to check your core speeds and voltage. flash your ln2 bios to a skynet bios so you can unlock voltage, and more importantly, unlock a 200% power target, along with disabling that gpu boost crap.

im on air and i benched my 780 at 1375mhz@1.285v core, cold winter morning, fresh start, side panel off with a floor fan. temps were high obviously, just wanted to see what i could get in firestrike and valley. my firestrike graphics score was a tad over 12000 and valley extreme hd was a tad over 3400.

under water at 1.30v you should be around 1400mhz core, a little lower a little higher depending on your chip. the classy controller has the pwm modulation as well as the memory voltage. i wouldn't mess with the pcie lane voltage, but you need it to for voltage control.

so i have classy controller and i opened it to see and interestingly it was at 1.30v, i have not used it in ages and last i checked it was set to stock! afterburner is showing the same info as precision but show's nothing about voltage, i enabled voltage monitor in settings but it stays at 0, should i run valley to watch it ping? also would it be wise to lower memory clock and boost core clock? maybe same temps but better speed?

I find the EVGA GTX 780 uses a lot of power. The 106% power limit is not only a pain for Overclocking but can cause the Core clock to ramp down in gameplay. Which of the two utilities do you prefer,MSI or EVGAX? And I mean EVGAX 4.2.1

i prefer evga's ut, it's 5.4.1 now and it's simple and seems to work well.

oh and power limit bumped to 130%

oh and power limit bumped to 130%

on EVGA Precision? I tried to use 5.02 i think and it was not working out that well and was not stable for me.

 

[nikoli707]

everybody uses msi afterburner. otherwise find your overclock with msi ab then create a custom bios. for most, a skynet bios and msi ab is the best overall.

it's 5.2.3, it was a really recent update.
