Vaulter, which HSFs did you finally get for this setup (sorry if I missed it earlier in the thread)? They may be crazy loud but they'll get the job done. In my experience, the loud server HSFs tend to also be the coolest, which is something that isn't always the case with enthusiast components. There really isn't very many choices out there and the quieter server stuff is usually not the coolest, unfortunately. If you can manage to OC (a difficult if) you'll need the additional cooling these fans will likely provide. Trust me, stability is paramount with -bigadv.Holy shit, these fans are crazy loud!!! Must get a controller. I've got 1 CPU in now, I'll put in the other 3 and go from there
The only thing I can suggest at this time without knowing the various BIOS settings is to test each module individually, and if that doesn't reveal anything, test each CPU individually with different memory configurations. My dual-socket Opteron is very sensitive to BIOS settings. This is NUMA architecture and it might be more complicated/time-consuming to troubleshoot your setup. Also, you might want to test the PSU on another system to see if it is outputting sufficient power, but I do not believe that is the culprit.Ok, got all 4 CPUs mounted and 2 sticks per CPU. Takes forever to boot, but starts the post, all 4 CPUs are detected fine, and then it freezes during memtest, gets to 4 gigs even then stops, board number shows 60, which reads test extended memory. I've got to run real quick but I'll be back soon. When I get back, any more ideas besides swap some memory out?
Disappointed to see this project at a standstill. It's unfortunate the documentation isn't detailed enough to offer a possible solution. One thing I can relay from my Opteron experience is the placement of the memory modules can be very important. Depending on the type and size of the modules, sometimes only a specific order will work. Mind you, in such occasions the board would likely not POST at all but in your case it's freezing midway through the boot process, so I'm at a loss...Ok, well, bios options are out because it won't let me far enoigh to get into the settings. Illtry playing arou d more but the manual offers no help
I'll keep you posted and I've got more pics, but they are phone pics
My native Linux install has a dual boot with XP on another drive where I set my overclocks. If you install Windows first and then install Linux on another drive, the Linux installation will query if you want an OS boot manager. I suggest to select yes because it will be very easy to switch between OS installations this way.O it will get it, but while I'm playing around I'd like to have something easy to fall back on
Go into the BIOS and see what memory options are in there.Anyways, I'm having some stability issues, I'd guess it's memory related, keep getting reboots trying to enter windows, even thru safe mode
OK, no problem but we got to find what the problem is eventually, so I'm going to ask you to do something you might find tedious. I'm thinking like you it's a strong probability that the issue lies somewhere in the memory subsystem but what precisely I'm not certain without having the system in front of me. Give us if you can the following information:I'm clueless and I think I'm gonna call it a night, I've got to work again in a few hours, got to get dinner going
OK, there is no consensus about whether power plug adapters are fine or not. There are people who favor them and those who do not. I generally fall into the latter camp. For enthusiast-level boards and many workstation boards power adapters are OK. I have only used molex>4-pin P4 adapters and even they don't always work with every board I tried. I would be very wary of using an 8-pin EPS adapter. However, if there is no other choice, get the adapters that run off the PCI-E cables on the PSU, not the molex cable. Reason I advise this is due to better current available. Look here: http://www.overclock.net/power-supplies/551470-dual-eps-850-watt-power-supplies.htmlI got 2 8 pins, asked around and people said it would be fine. Every power plug on the board is populated
TBH Vaulter, I would start folding on this setup even without all the components installed just to determine if the basic configuration even works for prolonged periods. You could start with two processors and run regular SMP if you harbor doubts about long-term stability with -bigadv. Once you have a better handle on the situation, install the remainder of the processors and memory modules.It was fine with 1 quad and two sticks, only setup I havnt tried was 2 quads and 4 sticks
Then allow me to provide a consensus: they're fine. Based on the current capacity of the pins and wires, there is no way that the power draw will ever exceed specifications or cause failure.OK, there is no consensus about whether power plug adapters are fine or not.
Here, I will disagree with you Zero. Having run multi-socket boards since the mid-late 90s, I would be very reluctant to veer away from the manufacturer's recommendations based on the specifications of the componentry involved here. I'm actually quite surprised to see you being this certain about success with adapters and this platform, especially after having unpredictable results in my experience with lesser hardware. Even if it works, it will be hard to troubleshoot an issue of instability if all one has at one's disposal is an enthusiast PSU and adapters to test with. Best to adhere to manufacturer recommendations and eliminate as many potential uncertainties as possible with setups as complex as this.Then allow me to provide a consensus: they're fine.

If I remember correctly, the current limit for each molex pin is 9A. If that is indeed the case, then there is no chance of any failure so long as all the CPUs remain within their TDP (and it is very unlikely that they will exceed it by enough to cause an actual failure).Here, I will disagree with you Zero.

Yes, no chance of failure. I wouldn't be concerned with failure but with adequate current being supplied to the board to properly feed all the installed componentry. It might not be noticed at all but for the occasional lockups or crashed WUs that may occur once in a while. Something as innocuous as a random failed WU will normally be perceived as matter of course with folding, but it may also be out-of-spec hardware as the underlying cause. How could one really know the culprit? The user would not be able to confirm it because it's not something that can actually be tested without having an equivalent but compliant PSU at hand. The link I posted above gives me additional pause for concern on top of my inherent doubts.If I remember correctly, the current limit for each molex pin is 9A.

Using adapters won't affect the amount of current supplied to the board. That depends entirely on the PSU and the board itself.Yes, no chance of failure. I wouldn't be concerned with failure but with adequate current being supplied to the board to properly feed all the installed componentry.
