After flash it reverts back to the start screen, you did hear a "bip" didnt you? when flashing "she" always beeps! tongue.gif
Anyway reboot and check the load default core speed, it should be 1006mhz! thumb.gif

So i followed your instructions, ran a benchmark at stock, so 901mhz core clock as per standard, it still seems to be "boosting" and throttling? not sure if the flash worked frown.gif

According to your image THE FLASH PROCEDURE IS NOT FINISHED!!!

You have to wait! rolleyes.gif

Do it again, this time let the flash finish! tongue.gif
Make sure the bios you put inside the EZ3flash folder and rename to x.rom IS indeed the right bios and not the stock one! this happens more than you could think! smile.gif

WOO!! it worked, rebooted and its running at 1006 gpu core clock, afterburner also allows me to raise the total power limit to 150! Should i immiediatly set this to 150 to start OC'in?

Ahaahahahah! Hold on your horses! tongue.gif

Read this to better understand the TDP from one of my articles:

"The PT is the increase of TDP (thermal design power) which is determined by the chips maker (GK110 =250W) but this is not a fixed value, refers to the maximum amount of power the cooling system, in this case a chip, is required to dissipate. The TDP is typically not the most power the chip could ever draw, but the maximum power that it would draw when running "real applications". This ensures the chip will be able to handle essentially all applications without exceeding its thermal envelope, or requiring a cooling system for the maximum theoretical power.
"TDP is meant to be the wattage of the processor at load. I say "wattage" because it is unclear if this is meant to correspond most immediately to how much power is consumed in watts, or how much heat is produced in watts, but as near as I can tell the TDP is pretty much meant to indicate both" GL



(where C is capacitance, f is frequency and V is voltage)

Now, you dont have to make complicated calculus or anything like that because you have this chip here:



It monitors real-time voltage and power draw and its where AB gets its reading from the VRM´s! wink.gif

Stock bios come with 250W TDP (AKA PT) so when its at 100% you will have 250W of power draw, if you increase it to the max stock 106% youll get: 250x106%=265W
The same is with modded 300/400/500W bios what you see in AB or precisionX is the percentage above what you set!
Ex: with a 500W bios (Slider set to maximum of course) you see 60% usage, this equals to: 500x60%=300W
YOU CAN DIRECTLY CONTROL TDP WITH THE SLIDER! thumb.gif

Now, why has AB a 300% slider while PrecisionX uses 200% for the same bios with the same PT?
Well, AB and precision have different interfaces so the readings are different for the same thing, just keep in mind the base TDP value and make your calculations from there
It doesnt matter what the % slider is in any program, just increase it if you having stutters or frame drops and when making calculations always make them from the base TDP:

aW x b% = cW (a= bios base TDP, b= OSD TDP, c= aproximate power draw)"

I know this thread is for the 780 and I post it on the classy thread, but I am just looking for some help. any input would greatly appreciated.

@ OccamRazor


I need help with a problem I am having with two new 780 classified with helix mem.

Before I reflash my bios I did a baseline benchmark with Heaven and Valley then, nothing crashed and the score was pretty good, I was like great better than my old once.

This is were everything went to Sh..t. I flash the bios with version 3 from the Classified front page, everything took, so great. I started overclocking with PT at 200 %. First I did offset up to a +200 before it crash, couldn't go over that even with the voltage set to 1.35. I went to MEM got that to +350 before crash. Now I tie the two together and everything crashes.

I dial everything back to zero with voltage to 1.25 and Pwr target to 200% still crashes, everything back to zero and no good, still crashes.

I am on a new windows 8.1 install, I did this for the new cards because of the problems I was having with the old ones.

My two cards are cooled by, two H55 and fans for the Mem, still using the front plate to aid with cooling and a fan on the back plate to aid with the cooling.

My temps at idle is 38degs for the first card and 35 for the sec card, at load my temp are 58/48 the highest it ever gets.

I notice the bios version for the new cards are different from the old cards. 80.80.31.01.80 and if I remember the old ones were 80.80.21.01.

I flash the cards back and everything is good.

Please I need some inputs or idea. I am about to go full water. I don't think it's the cards, I think it's something to do with the Bios.


Thanks

Great article, so by me increasing the power slider, it would essentially give me more overclocking headroom and smoother play etc? With it being at 150 max, would this equate to me killing my gpu?
post #17319 of 24915
Just one other thing, so I know what I'm aiming towards.. what are the average stable clocks people have reached on their 780s under water? My core is currently running at 1350mhz mem is untouched and my temp is at 47 full load
post #17320 of 24915


So after a bit of Overclocking to what i believe is max stable, this is what i got!
