Looking at the source code for the 'Advanced' tab I find in line 44-46 the following:

var dieFreqTemplate = $('<select/>');
         $.each(config.valid_die_frequencies, function(i, frequency) {
            dieFreqTemplate.append('<option value="' + frequency + '">' +   frequency + ' MHz</option>');

it looks like this is a lookup of valid die frequencies from a file named 'config.valid_die_frequencies'.

Maybe we just have to find this file and amend it?

@ capa
Thanks for the feedback. Did you try a more modest increase. For example 800?
You say it blanked out the value in the web interface. But did the miner continue to run at 775Mhz?

Hi out there.

I am quite newbie to overclocking my October Saturn and have so far limited myself to using the new 1.00 firmware to increase clock frequenzy from 750 to 775 Mhz and it worked out fine.

I made a configuration backup (under the 'Upgrade' tab) and looking into 'advanced.conf' I can read the clock frequenzies mentioned at 775 Mhz as expected.

Since the miner probably does not actually uses the value '775' directly when setting the settings internally in the miner I would assume these frequencies/values refer to a list somewhere which interprets the clock frequenzy into a hex. For example 775 interprets into 1E1 if I read the list correctly. 1E1 is then used to configure the clock frequenzy. Am I correct?

So my thinking is that maybe the user interface of firmware 1.00 limits me from going higher than 775 Mhz on my October Saturn but I think KNC use the same firmware also for November units.
So maybe the dropdown list is limited to max 775 Mhz (because the firmware recognizes my miner as an October unit) but the actual list used for interpreting 775Mhz into 1E1 may be complete up to 1000Mhz (but only used for November units).

So my idea (which I did not dare to test yet...) is that I could change the 'advanced.conf' file to mention a higher clock frequenzy value and up load this new configuration to the miner which then finds a corresponding setting in the (hidden) list and voila... the overclocking is a reality.

Did somebody already try this approach?
What do you think about this? Could it work?

October Saturn

So I upgraded from 0.98.1 to 1.00 and all went well.
Without any further adjustments I went from WU 3943 to 3948.
Hashing though went from 284.4 to 282.2 but fewer HW and no rejects.

So I increased clock frequenzy to 775 Mhz and got WU at 4080 and hashing at 292GH.
So all is good.

I have the feeling my miner can easily handle a higher clockfrequenzy.
So I made a configuration backup and looked into the file advanced.conf and can see the clock frequencies are set at 775 Mhz.

Did anybody try to adjust this number up and what was the result?
I did not dare try yet. Somebody wants to comment?

Thanks searing for the tip. I checked and the fans are correctly installed.

My Saturn is hashing at 250 - 256 Gh/s.

However regularly cores are being disabled ("due to more than 10 HW errors) and then after a while enabled again only to be disabled shortly thereafter again.

During this process hash rate goes down to 150-200 Gh/s.
In the time the cores are disabled 5sec average is mostly around 266 Gh/s.

So I get the feeling that it would be better if those cores were disabled once and for all.
But maybe the new upgrade will fix this issue.

I summed up the cores that are being disabled: 11, 12, 14, 16, 17, 18, 19, 26, 29, 33, 34, 35, 38, 40, 41, 42, 43, 46, 47
Probably even more but those are the ones I have noticed.

What about you guys? Are you getting similar symptoms?
Is it normal?

Wouldn't this be to centralize the hashing power with KNC to some degree?
I mean if they control the only interface for configuring my miner the only option I have left if evil forces take over KNC  is to switch off my miner... I would have no possibility to reconfigure then?

Thanks for your inputs. That is exactly what I was thinking however this is just an assumption. Does somebody in here have experience with the heat sinks/coolers KNC are using?

Any opinions on whether it is OK to place the miner on the side (standing up like a desktop PC) instead of lying down flat?

Would this put the fans under extra stress? Or maybe other bad things could happen?

My very second post in this fantastic forum!  (First one was in the newbies' forum)
Thanks to most people for valuable inputs...

Anyone who knows how we will be able to adjust our miner settings?
Pools, worker names, passwords etc.

Does the Beagle bone board has a video connection or do we have to use SSH or a web interface?
And what about keyboard connection?

It would be great if someone who actually knows could answer. Wild guesses are not so helpful.

The reason for asking is because I am not a genuine computer wizard and am hoping for a relatively user friendly interface.

On the KNC forum I once asked if the miner will come with a user manual but no reply from KNC as of yet.
Though I am glad KNC used their time to work instead of wasting time on silly questions and FUD.

If my questions were already answered earlier I apologize for it escaping my attention. I have followed this thread for months now but I do not remember this question has been answered clearly.

Hello Bitcoiners!

I am new to this forum but have been a Bitcoin believer since February when I started mining to learn more. A lot has happened since and now I feel the need to be able to participate in discussions in this forum.
So this my first post is to honour the brilliant system of restricting spammers and jerks from contaminating a nice discussion board.

Looking forward to being able to post.

Have a great day out there!
