LOL...

Sorry for not taking the bait. :razz:

You'll be pleased to know that your DC matches my TC.

[QUOTE=flashjh;361218]Just lost my watercooled system due to a leak. Have to wait until Saturday to see if it can be salvaged. If anything is broken, it will take time to get fixed, so -~1400 GHzDays/Day until it comes back up (if ever) :no:[/QUOTE]
Alright, it's back up and running, finally. After several weeks of mailing parts, troubleshooting and an awesome friend who did the waterblock swaps, all 4 cards came back online.

BTW - [URL="http://www.gigabyte.com/products/product-page.aspx?pid=4334#ov"]This board[/URL] is awesome! Discovered that one of the waterblocks was leaking all over the board and then it received a gush from the break. After cleaning the corrosion off, it's still able to handle 4 cards under full load with the CPU maxed out as well. Highly recommend if you're in the market.

Thank you! :smile:

Coolness!!! (Joke intended... :wink:)

Thanks for the news Jerry! :smile:

We seem to have lost TheJudger? No assignments in GPU72 suddenly....maybe everywhere?

Not lost (at least, I hope).

Oliver let me know that he wouldn't be doing any work for at least two weeks over the holidays.

And since his processors are Xeons running at 2 Ghz, that got me convinced that we are really not lacking computing power, but just data moving capacity. So instead of focussing on processors our comparing charts should be about motherboards, chipsets and memory technologies. Anyone an interest in implementing that in the GIMPS clients?

Sorry, I don't understand. Care to expand? :smile:

The bits are being reordered like in a multiplication, and they are being moved like from a register to a memory with all bits remaining in the same order. Basically every computer program does just these two things. George will be the one who can best tell which operations are the most critical and what the bottlenecks are inside a computer running Prime95. But reordering the bits is not the problem, getting the bits to the places where they are being reordered is what limits work being done.

I'm not understanding you either. I don't think the chipset or motherboard is of serious importance, unless that component happens to outright malfunction.

Up to a point, the CPU is the biggest consideration. At a point, memory and CPU become equally important as the memory can become too slow to keep the CPU fed. As far as I know, the "speed" at which bits are moved between the components is basically negligible.

ADDENDUM: I would be utterly shocked if you could tweak Prime95 to make a 2GHz Xeon run as fast as a 4 GHz 4th gen i7.

ADDENDUM: If I understood you correctly, you figure that because Chris is a big player with Xeons, Xeons must be really good hardware. 6 "okay" computers can do a lot of work, not counting any GPUs he may be running also.
