That makes me feel kinda bad. *looks up price of i7's* Ok, now I don't feel so bad! $289,$560, or $1000 depending on the model. (from Newegg) Wow. My CPU cost$100 about 17 months ago, it's around $50 for an equivalent one now. (sounds related to Moore's Law) Which i7 do you have and what clock speed is it at?  2009-04-17, 13:57 #46 IronBits I ♥ BOINC! Oct 2002 Glendale, AZ. (USA) 111310 Posts I7-920s. Get good, no, make that GREAT 3rd party HSF, go into BIOS and set BCLK/fsb to 173-174 and your good to go at 3.5GHz. It's a tad shy, but close enough and rock solid. Just fired up all cylinders over here. 5 hrs early, but better than being late to the party Another ROLP BBQ coming right up.

On a good note: It looks like the project picked off 5 primes (all new) in the 6 hours directly proceeding the rally. A precursor of things to come! Rollin', rollin', rollin'. Gary  2009-04-17, 19:56 #48 Flatlander I quite division it "Chris" Feb 2005 England 31·67 Posts I want one of those. For comparison with Ironbits' i7, I'm also getting ~60 per hour but I'm using a C2Quad @3.09GHz AND a C2Duo at 2.38GHz. A total of 17.12GHz.  2009-04-17, 21:07 #49 gd_barnes May 2007 Kansas; USA 100111011010102 Posts One of my 2.6 Ghz Intel quads is doing ~33 per hour. Not overclocked. A crappy AMD at the same speed is doing ~29 per hour. David I7's are 8 cores at ~60 per hour so that's pretty equivalent. Chris, you're getting some serious processing power out of only 6 cores to get ~60 per hour. It's taking 2 of my non-overclocked 2.6 Ghz quads to reach that. I can see that it's about time to add an I7 to my arsenal. I'll definitely be looking into that before the next rally.

A snippet of lresults from one core of a 45nm quad running at 3.825 GHZ [450x8.5] Thats about 55 an hour across the 4 cores. It's my gaming PC i don't normally crunch on it, except for rallies :) Last fiddled with by PCZ on 2009-04-17 at 21:34  2009-04-17, 22:05 #51 gd_barnes May 2007 Kansas; USA 2×5×1,009 Posts Oh, now that is just WRONG! You shouldn't be able to crunch that fast! lol Anyway, that's truly amazing. You should put that bad boy to use more often; i.e. at night or other times you aren't playing games on it. :-)  2009-04-17, 22:13 #52 gd_barnes May 2007 Kansas; USA 276A16 Posts I have a question for you techno whizzes and geeks: :-) Does it use more electricity to overclock a machine or to buy a new one such that both result in the same total processing power? More specifically: If I added 10% in speed to my 10 quads, that would be the equivalent of buying another quad. So...would 11 quads at "normal" speed use more electricity than the 10 quads overclocked by 10%? I think, though, for me, I have to get them running cooler first. I've taken a couple of steps and have now only blown 1 mobo in the last ~3 months, knock on wood. But I had enough problems with them before that that I think I'd need to buy some heavier-duty coolers before I overclocked them.$50-60 for a mobo is not a big deal but it gets a little expensive when you've had to replace 6 of them in a year. As Max pointed out in a PM at some point, I could have almost bought another quad for the amount I've spent on mobos. :-( Gary Last fiddled with by gd_barnes on 2009-04-17 at 22:16
 2009-04-17, 22:44 #53 PCZ     Jun 2006 Chertsey Surrey UK 35810 Posts Do you PC's all have harddrives VC's CD roms etc ? If they are fully equipped PC's then 10 OC'd would use about the same as 11 non OC'd. A mild OC to say 3GHZ woud hardly affect the power consumption at all. voltages all remain at stock. Processor will use 33% more juice but the rest of the components in the PC will use the same amount whether OC'd or not. A q6600 g0 uses about 95w at 2.4 GHZ. Running at 3GHZ that increases to about 127w, assuming no core voltage increases. What does a whole PC draw 300watts ? overclock 10 quads to 3GHZ and use 320 watts extra Use another PC instead of overclocking and its another 300watts or so. In my example the 10 overclocked PC's are have the equivalent crunching power of 13.3 non OC'd ones, but the power consumption equal to 11 non OC'd ones.

Gary, I7s are true 4 cores with HT which makes it look like it has 8 cores. Four true cores are doing ~60 per hour x 5 Last fiddled with by IronBits on 2009-04-18 at 00:24
 2009-04-18, 01:29 #55 gamer007   Mar 2009 18610 Posts Ahh.. you guys and your I7's... All I have is a Q6600, which did about 30/hour on stock. Now I'm currently trying a 2.66GHz OC, though I have a stock heatsink/fan so I don't really want to go too high. I'm also testing out a Pentium 4 (3.0Ghz) to see how it runs during this rally.
