Looks like I'll be the first voltmodded on Zeus.
The updates on Zeus voltmod will be posted on the thread you linked to keep this one on Gridseed blade

Can't believe you're using a cheap brick!
They blow up on you because they are made for intermittent peak performance, not constant!
If they were, they'd come heat sinks and fans!

Well done on getting the first Zeus overclocked!
Now to see what the actual results are, pool side.....
Keep your fingers crossed.

I think the HW error count is unacceptable already.
My 26 pods have been running steady at 1163MHz for eons and outputting maximum accepts (even better than running higher clocks) with virtually 0 HW errors out of the lot of em! hint hint.... Wink

Since the brick was free and I was short of ready to use server psu, I wanted to try and see how far I could push it.

Not far...

I'll set up a hashra or similar raspberry image tomorrow for the tests and with a server psu.

In fact, I did almost the same thing without seeing the thread. Arctic ceramique under the pcb and custom heatsinks on the chips plus fan blowing through like on the blade.

Hi all. Can someone recommend a stock fan replacement for a non-modded G-blade?
I'm looking for fans that are quieter than these stock fans without sacrificing the CFM amount?  I'm also hoping no mod is required to replace the fans with 3rd party fans.  If this has already been answered can someone point me in the right direction?  After filtering for g-blade & fans I kind got tired after 50-60 read hits.  Thanks in advance.

Regards,

Suzukii

Most of the fans you will find will come with 3 or 4 pins connector. You will have to keep only the black and red ones.
As for stock size, sorry, I upgraded to bigger one, Scythe ultrakaze.

I used this to choose mine

http://www.frozencpu.com/cat/l2/g36/c435/list/p1/Fans-12_Volt_Fans_by_CFM.html

The stock one is around 60cfm, don't go too low

Thanks for the info.

You wouldn't happen to know what size these fan are would you.
I was hoping to see if COUGAR had any since I installed these on my S1 Antminers & I can't even tell 8 of them are on in the same room.  The ones I bought made from COUGAR are model CF-V12HP Vortex Hydro-Dynamic-Bearing 120mm 70CFM rating.

Thanks again.

Will anyone possibly link some of the parts you purchased to volt mod your g-blades in this thread?
Curious
I'll do it this afternoon when I'll go on the computer. Too hard to do with the phone.

thank you Smiley it will be much appreciated

Here we go for the list

Hardware and related used

I don't work with magnifying glasses, but with headlamp. If yo do need a lots of contrast like me, this one is really nice and throws loads of light and is cheap. Maybe cheaper on some other places.

http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=290990217612&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

small tweezers will help for placing the smd too, something like these ones.
http://www.ebay.fr/itm/6PCS-Brucelles-Pincette-Pince-Tweezers-Antistatique-Metal-Courbe-Rond-Droit-/121204738469?pt=FR_YO_MaisonJardin_Outils_OutilsaMain&hash=item1c385d89a5[/b]]http://www.ebay.fr/itm/6PCS-Brucelles-Pincette-Pince-Tweezers-Antistatique-Metal-Courbe-Rond-Droit-/121204738469?pt=FR_YO_MaisonJardin_Outils_OutilsaMain&hash=item1c385d89a5

Soldering paste ZJ-18 one of the best cheap ones I tried so far.
http://www.ebay.fr/itm/Welding-Soldering-Iron-Solder-Flux-Paste-ZJ-18-50g-Wax-/220645967363?pt=UK_Home_Garden_PowerTools_SM&hash=item335f864603

Soldering station
Aoyue 937+ very good not so expensive one

Hot air rework station
BAKKU 858D
Cheap, but does the job.
My settings aren't the best ones, but they do work:
450°C (I know, it's way too high, but it allows me to work very fast)
Don't run the fan too high. 1 or 2 is enough most of the time. 5 will blow the 0402 and most of the 0603 SMD components off the board. Did I say not to go up to 8?

Standard mod
Resistors 0603 size 39k recommended, 43k is hardcore and dangerous, I'm running 44.2k.
can be found at mouser, farnell...

Heatsinks for cooling the mosfets under the PCB
37x37x15mm
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=261310293222&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
or 37x37x24mm (still waiting for them 5 weeks after puchase...)
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=310945950478&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

small heatsinks for cooling the mosfets on the top side
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=251251434021&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Optional improvements

Replace the power plug with a screw terminal, 5mm pitch
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=400667113340&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I had to slightly bend the pins of the terminal and drill the stock holes to 1.1mm

Replace ferrite beads with 0 ohm resistors, 1206 size
Axial ferrite beads might be better for safety, or resettable fuses. I ordered some and will test.

Replace Mosfets with new ones
Upper gate -> CSD16321Q5C one for each PCB unless you have the latest ones with an empty mosfet pad that you can populate.
http://www.mouser.fr/ProductDetail/Texas-Instruments/CSD16321Q5C/?qs=/qzd9s%252bcLd6BJ6oSO2jYyA==
TO-220 package IRFB7437 will also work with a nice AAVID thermaloy HF20 heatsink
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=360922735855&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Lower gate -> CSD17556Q5B you will need 2 of them on each PCB
http://www.mouser.fr/ProductDetail/Texas-Instruments/CSD17556Q5B/?qs=%2fha2pyFadujmDrK04JvA9%2fUT5iDlW7l0ImBsWKDB2WI%3d

add heatsinks on the GC3355 chips will help getting lower HW errors.
same one used on the mosfets


Optional wide body mod

Scythe ultrakaze 130CFM fan
You will need to figure a way to attach it to the blade. I glued some 15mm M3 spacers at appropriate place to be able to screw it.

25mm PCB standoff / spacers to make the original ones higher
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=281207608483&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Custom cut PVC cards to close the gap between the 2 halves of the blade size 220x120x3mm
http://cgi.ebay.fr/ws/eBayISAPI.dll?ViewItem&item=261480101060&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649


My recommended power supply (I currently own 15 of those at home, counting a few spare ones)

Server power supply, 1300watt if powered with 220-230V

HP DL580 G3 / ML570 G3 power supply 364360-001 / 337867-001 337867-501 AA23530
Quite easy to mod, reliable, not too expensive, powerful, but loud as a vacuum cleaner.

I hope my three blades haven't died...maybe someone with some expertise can help me out.

*edit--lights are flashing on the units, but hashra blade controla does not seem to recognize any units. I get "NaN" for the hashrates, and "loading" for the rejects.

Hi All:

I have a weird problem; been running beautifully and effortlessly for two weeks until tonight with three volt-mod blades on hashra blade controla.

Only thing that I changed tonight was I went from 988 down to 963, and now the blades aren't even getting recognized or anything on controla. I have previously switched around speeds without issue.

This sucks-- I always seem to have some sort of problem crop up when the profitability is high (currently 162% LTC on clever).

Help appreciated.

Lol those are exacly the same heatsink I've used for modding my blade, from the same seller too  Grin

I was interested for a hot air rework station and I'll give a look to your BAKKU 858D, as for soldering station I lately prefer the one's with self-regulating cartridge like Metcal ( only downside is that it's pretty pricey gear).
Anyway nice list, thanks for sharing  Wink

Can anyone speculate on this? One of my overclocked blades won't mine on one of the two panels. There is a rapid "clicking" sound now when i connect the DC connector to it, after a couple of minute the sound goes away. Does this usually indicate something? Thanks.

Clicking on the pods was related to the crystal.

Have you voltmodded them yourself? If so, try to revert back to check if the panel will hash again.
Apart for the cooling improvements, is there anything else than the resistor that was changed?
High quality pic of the power board could help to see something.

I hope my three blades haven't died...maybe someone with some expertise can help me out.

*edit--lights are flashing on the units, but hashra blade controla does not seem to recognize any units. I get "NaN" for the hashrates, and "loading" for the rejects.

Hi All:

I have a weird problem; been running beautifully and effortlessly for two weeks until tonight with three volt-mod blades on hashra blade controla.

Only thing that I changed tonight was I went from 988 down to 963, and now the blades aren't even getting recognized or anything on controla. I have previously switched around speeds without issue.

This sucks-- I always seem to have some sort of problem crop up when the profitability is high (currently 162% LTC on clever).

Help appreciated.

Here's my history:

Are the power MOSFET hot? You can also check the voltage across the big yellow capacitor. Stock should be 1.2 voltmodded is higher depending on the resistor used, up to 1.5.
If you have correct voltage, and if 3 blades failed at the same time, I suspect something software related.
Rebooting could help. If it's a raspberry, reinstalling.
Or trying another computer/ controler.
