Pretty long runtimes at the peak there, maybe it will manage max 10% higher RAC than your stock clock Q9550?

Btw, i cant wait for Apogee mount to come out, the urge is too strong and the i7 is running too hot if i go much higher than 3.5. Placed an order with vcore.dk today, international shipping wasnt too bad and i dont have to pay the Danish VAT so price is only DKK 318.40.

The apogee mount's out in the US for $10+ shipping. Dunno what that and customs would amount to for an international order.

I think my i7 now has the highest RAC for single socket systems, #102 on top hosts list, been moving quite fast upwards. Even with no waterblock and limited OC i got to say to the core2quads...

Hi, what is the frequency of your i7? My Q6600 @ 3.6 GHz gives me around 4200 RAC (4300 at good days). This was the fastest single socket system so far ;)

So it was yours. Nice RAC on that one, was thinking it was closer to 4GHz.

The 920 is at 3.5GHz core/3.5GHz uncore, RAM 1750MHz 10-9-9-26. Still using the boxed cooler, 80c +, not too nice, i am soooo waiting for the waterblock.

How come the fasted single socket Quad is a Q6,600, which I confirmed by looking at the E@H stats for hosts?

I see no 45nM core 2 quads competing, as they should have better outputs than a Q6,600 (depending what else they may be employed to do or clocked up to).

It is not. th3's i7 is considerably outproducing hotze33's Q6600. While th3 converted an existing host id so it did not start from zero, still the RAC is a long way from reflecting its current output.

Or are you arguing that the i7 is not a quad? It is, by the way.

Message 88577 in response to message 88576

I think he mean Q6600 VS Q9000 series. No Q9x50 is fast enough at stock to compete with a 3.6GHz Q6600, and since most people dont overclock the odds for a 45nm challenger to Hotze isnt very high. In addition very many users divide their CPU time between projects, further lowering the odds.

Donald's QX9650 could have been higher up on the list, it had a 3200+ RAC earlier today, i think that rig should be able to compete with Hotze, maybe it also is doing other projects in addition to E@H.

I am currently over in MW with my QX9,650. Depending how I feel I clock this rig at between 3.9GHz and 4.05GHz on air. It ran stably when I was using it on SETI.

th3 followed and interpreted the gist of my question, which was not clear the way I expressed it.

I was wondering how come there was no competing 45nM quads against a 65nM quad.

Just enquiring

It appears to me that far more people bought Q6600's with the express purpose of using them for BOINC and overclocking them than did the Penryn-generation parts.

The initial price drop to about $300 for Q6600 in the summer of 2007 was quite an event, and when people realized that Intel was shipping most of the parts with an unusually large speed margin to spec the economy overclocking possibilities were pretty amazing.

To my mind, the Q9550 at, once again, about the $300 price point is the logical successor to this role--offering a superior performance vs. power consumption tradeoff to the Q6600, and with plenty of overclockable moderate priced motherboards on offer. But for some reason we don't seem to see much of that.

In my personal case, after a few hours of toying with overclock, I run my Q9550 undervolted at dead stock speed settings, which is now how I run my Q6600 as well. I think far fewer people do that than overclock. But on a life-cycle computation productivity economy basis it makes more sense than nearly all overclocking.

As to overclocking possibilities, I think Mark Sattler's famous "Frozen Penny" over on SETI is clear evidence that at least some of the Penryn-generation quads shipped respond well to moderate cooling (he runs his phase cooler open-loop, but I think it sits at something like -30C under load) and high overvoltage. He is currently running his X9650 at 3960 MHz with DDR3 RAM, and turning out a very high amount of SETI work. It appears likely to remain the highest single-socket SETI host until he takes the cooler off it to speed up his new Nehalem host, destined to become the "Frozen Nehi".
