With about 7 different mods, the titans can run VERY cool , AND without burning up the PCI-E cord. The true limit is a couple of dies at 300MHZ and no more than 2 dies at 325MHZ on titan cubes. IF you go beyond that, there is almost a certain chance of burning up the pci-e port inside the cude. With about 7 mods to each cube , the titan will run at 55C-60C all day long. This is one of my cubes that has been running for more than 24 hours. I even offer this service to repair and mod your titan cubes:

this is true about 1 month ago I dropped 2 dies down to 300 from the 325 setting on a hot vrm sets and had a 10c drop on the vrm temps as a result .did this for summer use..winter comes i assume i can pop the cube back up to 325 for all again when i don't have summer heat issues

but as to my other cubes running full out at 325mh i guess i'll take my chances (hey..its a race to doorstop status...fun fun)

Basically I had the October Jupiter for a while and basically overclocking is a horrible idea because it has very bad cooling. The cooling is good in an air conditioned room at stock speeds, but if you keep overclocking it, the temps keeps rising and rising.

The October one's were slower to begin with so the margin to overclock was less but I still got decent results with mine, I just added some cheap ram heat sinks to the VRM's and pointed a big fan at them, the november ones were much better though. Padrino's excellent firmware is very useful for tweaking them too.

Yes I had to do this also. Point a huge fan at the modules in the back but I am only running at stock speeds. Running it overclocked they would probably run at 70-80C.

Sadly, I cant find that script anywhere on titan, so...
Im not about to mess w/ SPI commands directly w/o knowing exactly what Im doing, dont wanna damage my hardware =(
So, 350mhz may be outta the question unless someone knows what to modify ...

according to this you can't overclock a titan it seems

https://bitcointalksearch.org/topic/m.12066180

remember originally the titan was only supposed to do 250mh or some such thus this seems to be a limitation

These was first method for overcloked Jupiter

After that method

Padrino

Make the best version for Jupiter so he know the way

https://bitcointalk.org/index.php?topic=313978.1020

There is absolutely no hint of how to do this on a titan in that thread.

No

Ask padrino

He will help you
He want also to make custom firmware for titan

Did you ask him? Huh

?.

Is super
Ask him

Hey all, sorry to bring this thread back from the dead but, question ... whats needed to impliment overclocked settings of the source code?
I see max frequency limits specified in waas code on github, is it really just that easy to change the field or is it more complex then that?
I couldnt easily search / find the info in this thread and wasnt sure if it evolved beyond the initial findings in first few pages.
Thanks

anybody???
at least if someone knows if it can be done or not

Install the unified 1.01 firmware, select a lower clock rate on the advanced tab and then lower the voltages on each die for each ASIC.
A watt meter would be useful to see where you are saving power.

I have a Nov KNC with 6 modules @ 1037 ghs so must be around 1000w needed power
In order to keep it, is there a way to lower the power per Ghs
dont mind the Ghs being lower as long as the power per Ghs goes down...
No SSH knowledge here If there is something that can be done with the settings
only please

Also is there anyway to monitor the DC/DC VRM Temperature. In my ADVANCED tab they are all 0

The VRM temps are only available on the November boards, best you can get out of the 4 VRM October boards is maybe 180Gh/s per board if you are really pushing it and you have swapped the fan out for a better one..

So I think I have the Oct 4VRM Build. Just wondering what the most stable OC are without frying this board.

Also anyone know why im getting FAULT 17 in one of my VRM settings?

Just picked up one of these babies.

Since I bought it used, is there anyway to figure out which batch my KNC Jupiter was built in? Doesn't say November or October anywhere on the boards.

silver vrms oct

black sqaure with yeller sticker nov

Ahh I see. I see 4 silver vrms.

I checked online and some have 8 silver vrms? Any idea why I only have 4?

cheap bastards...and i think they ran outta parts...who knows...its knc...be lucky the darn thing still works hehe
