This thread needs some.... ZIP TIES!

More Zip Ties!
Here is one way to attach a 38mm Delta to a megahalems

This is my first test build of "a few more" cost effective 920 crunchers. I plan on getting a case for it and push pull more quiet fans. The Asrock x58 board is running fine, and the 920 OC'd to 4.0GHz easily.

Not that I want to derail the thread, but pet hair can have the same effect.
I'm always surprised at how much of my cat's hair ends up in all the nooks and crannies of my case!

I'm sure the same thing happens if you run your computers in a room with the windows open...

I know it's an expensive habit, but personally I prefer to put my computers in cases and keep the covers on since it keeps the air flow predictable.


A bit touchy, are we? Relax.

No, he was right. I was being an ass. Sierra, I'm sorry I took it out my frustrations on you.

[skycrane]

Yeah, I kinda' figured that much.


I didn't realize there were non-PFC units without a switch on them. I have a couple really old 150 watt psu's with switches. Massive 5A on the 12V rail.


So, you've purchased new power cords for your 240vac compatible power supplies or replaced the plug ends with an appropriate end to fit one of these? (Actually, can the original 120vac cords even handle 240vac if you replaced the plug end? The one in my hand says 300V on it)



I was asking in this context.

Edit: I probably should have started my own thread for this. Sorry. /Edit

ive got a question then, why do you need to change the plug?? if the cord will handle the 240v, wouldnt the plug be able to handle it as well? its rated to handle 120v from the hot to ground, it should be able to handle the other 120v on the neutral/white side as well. Its not like your feeding 240 on just one side, your spliting it on each of the 2 sides of the plug.

for example, you can have the black as one leg of the hot, 120v
the white as another leg of hot, 120v
the green as the neutral/ground

the only thing you need to make sure is that you hook the white to the other leg that the black wire is, on the 240v main.

the wires in the house are rated at 600v, so there is no problem there. you just need to make sure NOTHING else gets hooked up to the outlet or you will really have some nice sparks

If you ignore code, you don't need to switch the plugs.

I need to prevent this from happening....and why I asked in the first place.

Now we know how you did it.

Here is my farm, from left to right: i7 920 @ 4.5 / i7 920 @ 4.2 / Q9550 @ 4.0

[snoro]

i think i have a title idea for srhunt3r: Antec fanboy cruncher !!!!

[sRHunt3r]

Whats not to like, fairly good pricing and great airflow. I use the 900 on almost all builds I do for friends and family.

[snoro]

My first case was a antec 200 so i understand what you mean.

[Jayster]

Dont compare to most others on here and ive just got into computers so that explains the packard bell motherboard

Whats that motor for in pic1, Nirvash?

[D_A]

Looks like a little air compressor to me.

[Nirvash]

You're right, it is a Thomas 2639CE38-190R that I pulled from a scraped O2 concentrator, its still on its shock mounts.

[snoro]

a little bump
i7 875k at 4.15ghz 1.376vcore and a gtx 470 watercooled by a gtx360 and a mcr220 and both crunching for wcg and gpugrid

i3 530 at 4.2ghz and a hd 5770 watercooled( hd5770 fan is so noisy at 70%+) both crunching for wcg and collatz

i5 750 at 4.1ghz and 3 gt 240 both crunching for wcg and gpugrid

and they are in the same room which is also my room. 31c ambient at the moment.

[hedge]

Nice setup there snoro. I really like the last picture. It shows your creativity when it comes to insuring adequate air-flow though the system. What is your output on those systems for WCG?

[snoro]

about 25-30k ppd for the i7, and for the other two well you made me realize that in the last days they had problem producing the ppd they normally do which about 20-25k for the i5 and 15k-20k for i3

[charged3800z24]

I only have three cruching, here is a PIC of the 2 at my home, the other is an 2 socket Operton quad core server at my office. I'll try and get a pick tomorrow if I get time.

As long as we're showing cable management I'd though I would show some of mine.

That's 2 X6 1055s running Linux on bootable USB drives with 1 650 watt PSU.

[josh1980]

Ok, how do you put 2 power supplies together? I'm going to be putting together a bunch of computers for crunching in the fall, and if I could put 2 computers into each power supply that would cut costs alot!

[nanoprobe]

You get Y splitter cables for the 24 pin and 4 pin ATX plug. Both the mobos in the photo are Gigabyte and have 8 pin ATX plugs. The PSU I'm using has both 8 pin and 4 pin ATX plugs so I just ran one to each board. Since I'm not using regular HDDs you could even get a 4 pin molex to 4 pin ATX adapter and use that to power the ATX plug on the mobo. I've done that and it works very well. If you're going to do this don't skimp on the PSU. I would recommend at least a 650 watt with an 80 bronze rating. You'll need separate power and reset switches for each mobo cuz when you fire one up it will start all the fans but will boot only the one you started. I use a KVM switch to control multiple crunchers with 1 mouse, keyboard and monitor. You can get Y splitter cables here. I have dealt with them several times and have been very satisfied with their service. They have just about every splitter/adapter you could ever need.
If I can be of any further help let me know.
