The team is now sitting at 445th place. :-D
Previously the best was 446th on the 14th of March 2007 before we slid downhill.

Awesome!!! I've been waiting for this day to arrive!

Although my production has slowed a little (my father-in-law discontinued his internet so that he could pay for his new car more easily - no more X2 3800+), I see you 2 continue to crunch like no tomorrow. That should keep us rising for a while! :)

I'm RMAing the motherboard of my Q6600.
So as of last night my daily credit is going to be in the 1000 range for awhile since GigaByte won't do prepaid exchanges and turn around will take some time.

I will probably replace the board during the week as it is also used for my work.

To look at the bright side that will leave me with two 775 socket motherboards at some point which may just provide enough leverage for building a second Q6600 box since the CPUs are pretty cheap these days.

No RMA required.
After some testing, swapping and head scratching it turned out not to be the motherboard, but a power supply.
Too much stuff in the box on one 12v rail in combination with carpet fluff and cat hair causing a repetitive shut down and reboot in an endless cycle.

So we's crunchin' ag'in. :-)

Well that must be a relief. A bad motherboard is a big nightmare.

I actually thought I might have to RMA my motherboard for my Quad too. I was having issues with it freezing, rebooting, & reporting the wrong amount of RAM. Well after reading forums on ASUS' website, I had to manually set the NB & RAM voltages manually in the BIOS &, oddly, there is a memory hole when the BUS speed is set to 800 MHz (same as what my RAM is supposed to be at). So the solution is to change it - so logically I overclocked it instead of underclocking. Also I upgraded my video card & found out my UPS is no longer powerful enough to support my PC so I'm bypassing it at the moment.

And at the same time I figured I would overclock the CPU by 7.5%. Still had 3 freezups since but only when playing Titan Quest. so I may have to slow it back down. CPU temp is around 51-53 C so I assume it's OK. Though I am using the fan that came with the CPU so I wonder if I should upgrade the fan.

Hopefully my RAC will start to recover, I was a sitting duck ready to be pounced on by felis notebookis wildus. ;-)

I actually bought an inexpensive motherboard an Asrock 4Core1600P35-WiFi to tide me over, after having tested all the separate components as OK on another machine it seemed like the thing to do.
It's sitting there in a box and I'm thinking.....(To be continued.)

Most boards default to the standard 1.8v for DDR2, most high performance RAM will run at that voltage with slack default timings but most require something over 2.0 volts to run to maximum specs. A lot of times a hole in the speed range is an indication of an unsuitable default timing parameter in the BIOS setup. Wade through this article and get to the section on tRD, interesting stuff http://www.anandtech.com/mb/showdoc.aspx?i=3208

You're on the right track then :)

Don't get me going about consumer grade UPS and the nightmares I have seen, a decent powerbar and a journaling file system makes for a pretty safe system IMO.

Yours is a GO stepping so it is rated to 71C by Intel so I think that is safe enough. My B3 stepping is rated to 62C but running the Thermalright Ultra 120 Extreme cooler it stays in the low to mid 40's @ 100% load despite the hotter running B3 chip with the Voltage at 1.325 and and 8 x 400 clock.

If you are using automatic setting to achieve your overclock switch to manual and bump the CPU voltage up a bit. IIRC the maximum voltage to maintain the warranty is 1.3 volts, check the CPU box to be sure, that might cure the instability.
Find and install Prime95 v2.56. I find it is a quick way to test for instability when playing with BIOS settings and that version works all cores at once.

>Though I am using the fan that came with the CPU so I wonder if I should upgrade the fan.

A good idea for an overclock, cool is good, I started with the Arctic Cooling Freezer 7 Pro, which did a pretty good job and was cheap from DirectCanada, I have since switched to the above mentioned Thermalright which dropped the temperature a couple more degrees, but the thing is tall and may not fit in a narrow case.

Happy crunching,

UncleVom

PS Don't forget to tune in for the next weeks episode "Culling On The Farm".

Another shake up, I'm down to 4 machines.
2 Q6600's, the AMD 4200+ and the Sempron 2400+ entertainment box. No dedicated crunchers.

I'll do some further OS shuffling at some point with one of the quads becoming a Windows box and the 4200 becoming a Samba file box, but I probably save that chore for a rainy long weekend as swapping WindowsXP and apps to a different box tends to suckle.

Here's to higher heights for the Team and hopefully an 8000 daily credit and a not too much worse an electric bill for me.
