this is shocking

Fulcrum · 10 May 2006 at 23:30

I think it ruins the whole underdog idea but yes they recommend that mobo because it can handle the 400watts with 8 voltage regulators :confused:

If I do this it'll be with something cheaper and I'll settle for less then the 4.1ghz stable they achieved

Average price of a kWh is £2.46... this cpu is using about a 1/5th of that, or just over yeah? so thats 49p per hour just for your CPU consumption... running your CPU (not your whole PC) 24/7 would cost around £4309 per year! :eek:

Thats at full load, both cores though 24/7 which would never happen, but thats an expensive running cost lol, Still think of the money you'd save by being able to heat your house with just your PC! :rolleyes:

I may have got the above totally wrong, but i've tried to work it out from my leccy bill lol. Anyone get a more accurate pricing on that?

Try 8p per kWh

so 1.6p per hour, on 24/7 thats £140.16 per year and it would only use 200w with a massive OC and very high voltage.

Fulcrum · 10 May 2006 at 23:37

I think you have the kwh wrong, its something like 10p isnt it. If you leave a 100w bulb on for an hour it really costs pennies.

I only have a 450w PSU, I dont think it'd cope even though my gfx is just a 9800pro.

Do we know if the OCUK 805 cpu is the right version, stepping, week, etc for this overclock.

I presume all the ones at auction will be older versions

Foehammer2003 · 10 May 2006 at 23:39

lol er...

ahem *shuffles around*

well..... er yeah! brb...

Still a lot, just for the CPU, even a third of that.. for one chip!?! Add SLi, fans n stuff.... thats a lot to run a PC over a year...

Oh boy :rolleyes:

i was looking at the rates on our gas bill lol, how embarrassing, dam my mrs and her inate ability to make me look stoooopid! (She filed it under leccy!)

Yeah thats a key question id like to know aswell

megatron · 11 May 2006 at 00:38

I believe there are boards suitable for this chip which accept DDR400.

Even if it was 200w of waste energy the scythe would only be ~10c higher than your single core opteron.

The review says they measured 146W over stock at 80W , 226W at 4.1GHz. The scythe with a thermal resistance of 0.17C/W to dissipate 226W gives a deltaT of 38.5C and with ambient at 20C (or more for case temps), it'll run at 58.5C. A 2.8GHz single core Opteron uses up to 104W. Using the scythe and the same figures the opty would run at 37.7C. A difference of 21C.

Mines 11.4p/2.3p day/night, or £2 per kW/day. Against say an opteron [email protected] it uses maybe 100W more. Not forgetting the PSU efficiency, then that's 135W. Works out to £96 in a year without considering the extra cost of cooling and assuming its left on running flat out 24/7. If it not on all day or idling with a few hours at 100% load a day it got to be a 1/3 of that. At that rate it would take 6 years to pay for the 170. But add the motherboard, memory, bigger PSU....

I bet these will sell like hot chips forgive the pun

, Like the opti they will become quite rare then intel will review the chip and chop it down and cut its legs off so it dont run quite as fast.
I orderd one the other day when I got wind of this, Just to have a play with.
If nothing else I can heat the conservatory in winter with it. And play fear at the same time.
I say have a go and have some fun

well we're not talking about running these at stock, are we?

Hmmm.. He didn't say at stock James, he said using 'stock cooling'. I think meaning not using more powerful and therefore more electrical-consumotion-expensive coolers.

[edit] I'll just read the first page and comment on that shall i? - never noticed the other pages :rolleyes:

So will the motherboards that the article sugests to use run the conroe chip when it comes out? this would make a lovely cpu upgrade path availible.

And if it does, does this mean that some faster memory would be a better bet that can keep up with the conroe chip later on?

mrthingyx · 11 May 2006 at 13:01

From my understanding of the Conroe chip (limited as it may be), no, it won't. The Conroe might work with some of the newer chipsets but there is no guarantee.

2StepSteve · 11 May 2006 at 14:33

Would this 805D CPU (clocked at say 3.4Ghz) be a big jump from my AMD64 +3400 754 socket?.. In games aswell? Looking for something to match my X1800XT I just bought

I have DDR400 ram would that work okkies in it when its clocked? Looking for the cheapest options really

They won't.

Conroe will work on: new revision i975 boards (not the ones available at the moment), i965 and on the new Asrock board using i865.

Yeah just reading about that, ah well will have to wait for another few weeks before playing with new kit (sigh)

At 3.4 I dont think it would, because games dont use the dual core much but 4ghz would

MikeTimbers · 11 May 2006 at 17:29

Don't forget that to get to 4.1GHz in this article they used water-cooling so add that to the cost of your upgrades.

their temps seemed really high though, with stock cooling they were unable to run @ 3.33ghz whereas I'm at 3.6 no problem.

MikeTimbers · 11 May 2006 at 17:43

Wasn't their ambient quite high?
