Memory incompatibility is rampant these days. Did you check the sticks with Memtest86+ yet?

Usually, a BIOS upgrade fixes incompatibility issues, but not all the time.

Seagates run really hot if they don't have good ventilation. Hitachis are much more reliable when it comes to their firmware. (Did you know Western Digital is just Hitachi drives rebranded?)

No work here. Maybe we have to wait for another channel to complete on the splitter.

I'm still concerned about ventilation after seeing that picture. If the new servers get too hot, the project is at risk of going down again.

I'm hoping any ventilation issues would be resolved before the servers come fully online. I'd keep it safe and make both servers very well ventilated and not on top of each other like in the final picture you took a few posts back.

Google's updating Stanford to higher percentages of Gigabit fiber use, I guess it would take action from them to install Gigabit fiber to the Space Sciences Lab.

General Tip:

Memtest passing is not the whole story, Memory timing settings being too tight can also cause IO errors that aren't detectable by memtest.

From overclocking experience, sometimes rated timings do not necessarily mean stable.

OK, now I get it, this is a workstation that can't really be modified or put in a different case. You could try an external solution like a Magma Expressbox: http://www.magma.com/expressbox2.asp

The 240 only uses ~69W max so it should work with this box. The 250 is cutting it kind of close though at 150W, it could blow the PSU.

Or if you're willing to get another GTS 250, here's the Newegg link to the Sparkle low profile 250: http://www.newegg.com/Product/Product.aspx?Item=N82E16814187098

Don't do that. Move all the Dell components into an Antec 300. Thataway you can fit a full height card in your system and not sacrifice anything.

I hear SSD talk in this news post...

Avoid Kingston and consumer OCZ products when it comes to SSDs. Intel is only good if it's SLC memory and if there was an SSD move made, that SSD must have a supercapacitor to handle Server IOs per second. Pretty much the only choice when it comes to Server SSDs is the Sandforce SF-1500 controller chips with supercapacitor.

First, get the new controller, then get Spinrite to rescue the data and move it to a new drive.

Wow, I just ran Windows 7 Ultimate 32bit and had to do the ipconfig /flushdns to even get it to work...

Will I have to do this everytime it fails?

Since there is no network link capable of delivering WUs from Arecibo, (but hopefully the Allan array might have one) and the prospect of failing drives, is a move to SSD swapping between Arecibo and the splitters feeding out the data to the WU servers in the near future?

Hopefully things will clear up after the outage today.

Splitters are down and we've run out of work, shut down your BOINCs for now. (unless you are running other projects)

Can't get any work. Looks like the splitters aren't fast enough, no work units being sent.

The Upload server was taken down prior to Tuesday maintenance.....so I would have expected an update in the 'Technical News' section to accompany it, that is all.

Unfortunately, this basically means that I will not be able to participate this entire week because once I FINALLY get the 400+ WU's uploaded from the machine I am sitting at, it will be time for another outage........and the fun starts again.

This is part of the frustration I feel, as well as others.

I use Seti@Home as a benchmark and stability testing tool.

I am currently considering ABORTING all 400+ outstanding uploads (and growing every minute) that I have so that I can download more new work and continue to 'test' my machine's stability. Is THAT another alternative ?


Prime95 is another really good stability testing software. It also stresses the system more so that you can be sure you have safe overclocks for example.

Downloads have been on the frisk for quite a while, even after the re-introduction of 2 download servers. It's symptoms are similar to the problem when uploads are maxed out.

The DB purge is now running, but the scheduler process is still not running. Maybe we're waiting for the splitters to pick up the slack before work is sent out.

I can certain say that the title holds true for right now.

But, I'm running out of work again... check the queries if there's anything stuck again...

Edit: Never mind, the work just took freakishly really long to get via scheduler requests...
