Hey Occam / skyn3t!

I have a question, I noticed when I start bumping my GPU core clock higher the base voltage also goes down (set at default - 0.950 v).

@stock 1084 MHz the min voltage in GPU-z is 1.1 v once I go past, here are the results for the minimum voltage (GPU-z readings):

1084 MHz (+0) - (1.100 v)
1111 MHz (+26) - (1.075 v)
1137 MHz (+52) - (1.051 v)
1163 MHz (+78) - (1.039 v)
1189 MHz (+104) - (1.027 v)
1202 MHz (+117) - (1.014 v)

Once I do manually adjust the voltages they do stick though, but I have to manually change the voltage manually each time I load a profile. Aren't you supposed to be able to save the voltage you set for each profile? Is this a bug or an issue? I'm using the latest BIOS for the Galaxy HOF 780 Ti made by skyn3t!

Thank you!

I just did some testing with EVGA P. X. and it seems like there might be a bug. Please try to use GPU-Z to test the real voltage.

- On a side note: I have been doing some litecoin (Cudamining) with my card on stock voltage, stock speed etc. The core never exceeds 74 degrees and that is the same with the old card I burned so I think the issue with exactly the EVGA GeForce GTX 780 Ti Superclocked ACX 3GB is that the VRAM/Voltage area of the card burns out, because after just 1 hour maybe less, you cannot touch that card without hurting yourself badly.

I wrote EVGA and asked if I should be worried about this and will post the answer from them. Hopefully this can help someone else there like me like to mine while not gaming.

Today I will be trying some gaming and benchmarks with the case open to rule out high temps on the vrm section of my asus card and see what happens. I have noticed since this whole vrm issue that I so much insist upon (sorry guys for being a pain) that during 15-20 minutes of gameplay (any game) the card will boost to 1084 and then go down all the time to 1071. Do vrm temps affect gpu boost also? Will the vrm cause throttling too or is it only with the proper gpu chip?

Hi, just want to give some feedback of my 780ti...

I have (almost a month) one MSI 780ti TF OC Gaming with the great skyn3t bios (thank you Sir.)
Didn't loose any time with the stock bios, and flashed in day one the msi skyn3t bios.

It can bench Valley and Fire Stryke Extreme at 1330/7800 for at least an hour (never tryed more),
but most important for me, it can play BF4 (and any other game i have) at 1080p ultra, for long hours, without any problem.
It crashs if core goes above 1350 and memory above 7900, but it still works for some time (but with some artifacts in some cases). ASIC is 71%.

I overclock using nvidia inspector, i have two shortcuts (.bat files)
One to force idle mode (at startup) and the other when gaming, with the clocks i mentioned.
I use MSI Afterburner only for the OSD and to apply a custom fan profile.
My temps will go from 50º-60º when gaming (BF4) or 70º when bench Valley/FStryke. At idle it stays at 22º-26º.

So i am very happy with this card with this bios, super performance when gaming and complete silence,
when idle or when using my PC as media-center.

I saw that there is a recent skyn3t bios for my card, the "skyn3t MSI gaming"...
I read there are some problems flashing it ? It's safe to try it ?

Thanks.
JE

My post above does mention that the voltages were based off GPU-z. thumb.gif

Yes I am sorry. I just installed the custom rom for my own card and have the excact same issue - the voltage drops to default when I change profile.

That would be nice if that could be sorted?

Hi everyone!

I just installed my second GTX780ti. I`ve tried to flash the second card the same way as the othet. My first gtx card i can get to 1.212v, but the second only 1.200v. Does anyone know whats wrong? Just a pic of my current rig! smile.gif

Same brand, model and batch?

Yes, the same.

Hi, just wanted to post the update from EVGA regarding mining with Cudaminer.

They are clearly very evasive in regards to this question, but they are not saying directly, that the cards are unable to either. - This is the reply I received:

Dear EVGA Member,,

Thank you for your purchase from EVGA! We like to make sure that you are receiving and will continue to receive a great experience with your EVGA product.

Have you looked inside your system recently? Dust can be a tough foe against your hardware and EVGA is here to help. Take a few minutes to open up your system and make sure your system is running clean and cool at the same time. Here are some simple steps to keep your EVGA product running for a lifetime of use.

1. Every 30 days get some canned/compressed air and clean out your system. Dust can cause heat issues which can lead to hardware failure if not maintained and cause an unwanted RMA in the future. Remove your components one at a time to thoroughly clean them. Take the time to keep your system clean and keep it running.

2. Preventing dust is just as important as keeping it out of your system. Some cases have built in filters to prevent dust and build up from entering your case. Make sure to clean or replace any filters to maintain good clean airflow into your EVGA system. Don’t have any filters? Take a look online for some simple ways to add filters to your case and keep it clean.

3. Running water cooling? Have you flushed your system recently? Water cooling can become a nightmare if not maintained. Make sure to flush your system to prevent mold, algae and build up from creating complications. Make sure to clean your system fans at the same time, blocked air flow on your radiator can cause just as much trouble.

Following these simple steps to maintain your EVGA system will improve your gaming experience and keep you fraggin’ for a lifetime.

Thank you,
EVGA Customer Service


The above can seem a bit strange, as I registered the card yesterday and informed, that it is a new card due to RMA of the first card.

However, I will mine and if the card brakes, well then I must simply RMA again.

I hope someone here can use this information to something.
