Those little annoying F@H things ..

Hi guys, just to let you know that I'm leaving the fold temporarily.

There have been a few issues with my folding rig & where its located - hopefully I'll be back with some better hardware and it'll have a permanent home...


Be nice to see a 'folding rig' project log tbh
 
My AMD cards are getting almost all 9411 WU's, guess there is a shortage of 9201s so PG opened 9411 to AMD cards. Not so great when these only produce 60-70% of normal WU's:(
 
I have been up to my old tricks again (Soldering Iron + PSU).

Picked up a HP Z600 to replace the XW6600, and thanks again to HP their mid range workstations only come with a single PCIE power connector.

Only this time, the set up for the power delivery was actively going against piggy backing a second connector off a standard molex. It seemed to be working fine for a while folding away on the GPU but then the restarts began to kick in.

Turns out, the one dedicated power line for the GPU wasn't dedicated at all. it was sharing its 18 amps with the storage drives and everything else that could be attached to the single wire that was home to molex and SATA power cables.

The strange thing is there are two other 18a power lines feeding into the motherboard on top of two 14a rails for the cpus and another for the memory. So there is plenty of power to go around, us stander users just arnt allowed access.

So as before I have cracked open the power supply and soldered in two wires to feed the GPU so the load is going to be balanced between the three rails. Just wating for the shops to open to go and grab a PCIE power connector.

I gave it a dry run with MSI Afterburner & Kombuster and, with the wires just held in place it didnt restart where as before it would instantly cut power.

Once I have an connector I will give the thing a proper test and then should be back producing points again.

Nice MacGyver-ing, any pics to go with it?
 
I will try and sort some pics out for those who are interested.

For a folding box a Z800 would be a better choice because it has better support for multiple power hungry GPUS.

Had I have known how limited the PSU would be in the Z600 I would have waited a little longer and grabbed a Z800, but what's done is done and I seem to have got around the issue at least for now.

The problem is because the PSU is very bespoke for the case, its not really possible to replace it.

It's a very nice workstation if you don't want to mod it. If it really didn't matter looks wide, one could buy a second PSU just to power the GPUs and situate it outside the case.

With regards to the PCIE power cable. I found a nice braided cable that was only £1 more than the crappy one. So I bought it thinking it will make things nice and simple to install and would look good as well.

Well, it was a PCIE extension cable and idiot here cut the wrong end off, so I then spent the next hour or so soldiering the cable back together and then into the wires I had soldered into the underside of the PSU (for ease of access).

The result is fairly clean, but it would have been much nicer had I cut the correct end off the first time.
 
I'd be interested in seeing some pics :D

Due to the very hot weather, I've had to pause folding for the time being. I'll be restarting once it's cooled down a bit. My GPU's hitting 94 C and I'm not comfortable with that.
 
Hopefully he's just on vacation. Have to admit though, I'm somewhat worried about him lol, hope he's all right.

Activity usually slows down quite a bit in the summer due to heat and vacations so this is pretty normal. Tends to pick up again when the temps go down.

Yeah, hopefully that's all it is :)
 
Hi guys!

I'm OK just was down for awhile because we moved. Finally got internet installed a few days ago. Got 3 machines up and running yesterday, not sure if I'll return to my former numbers though. I sure didn't miss all that fan noise....

Good to hear it was just a move. Did you move far or still in the same city/town?

I built a new rig to replace my old work rig (x99 :D). Grabbed a 960 this time around, such an itty-bitty card.

Same town, just outside of the city limits on the golf course.:D
