A start..2600K and Intel Burrage board

[retro77]

no..

Thanks...looks like CPU cooler is on the shopping list...uggh.

[WFO]

^^ So you like SB huh?
I played last night and ran at these settings for 12 hours stable on WCG:

That 4736 looked pretty sweet for the v-core. Why not use that 24/7? Summer heat?

Movieman as a 980X fan I must admit that the Sandy Bridge seems a very interesting proposition.
If you later confirm (I am eager to get this info) that at 120-150 Watts consumption your 2600K can run stable over a week with air cooling and say with acceptable core temps (max 70 C) and have an average over seven days of 50k or more then I will bow very low. This means that a 4 core would equal a 6core at nearly half the power consumption and one third of the price. It is just astounding. It will not change my standard platform that will remain until 2012 at least the X58-980X couple.
I hope that these improvements will be integrated in the future generation that will replace the X58-980X platform with octo and decacores.
Nevertheless I would like to see an exact clock per clock performance test on WCG between the 2600K and 980X. Say with both at 4.2 Ghz with air cooling.
Now I can understand the major breakthrough in power consumption, but I do not understand how 4 cores beat 6 cores at clock per clock. This means that the 2600K can process more instructions per clock and or more floating point operations per clock and the improvement ratio would be of 50% which is enormous.

I don't believe that, but please prove my wrong .

My guess is that the CPU's running over 1.3v are pulling close to 200W out of the wall socket. I don't trust the Kill-A-Watt to measure power consumption. The only thing I trust is my monthly utility bill to tell me how much electricity is being used.

[shoota]

MM make sure you have that kill-a-watt set to Watts. I know it sounds remedial but i used mine the other day and was like but had forgotten it defaults to amps or something like that, not watts

Right now on WCG at 4500+ at 1.35vcore and killawatt must be broken.
'Showing 119-119.1w and that can't be right
Temps running 52-57C according to realtemp

119 sounds like it might be volts.???

[EtaCarinae]

For info the comparative specs by Intel between 980X and 2600K. From that it is impossible to expect such performance level from the 2600K.

119 sounds like it might be volts.???

Bingo! 119 - 119.1 is most certianly volts (the default reading on a killawatt .) These next few days should give us better SB numbers, I would expect 6K boinc in the upper 4GHz range.

WAAAY over what I'd normally do just to do a to my good buddy Hicks!

Oh Hicks? This buds for you pal!

Ok...Low of 15f tonight. Time to open the basement window.

BTW, whats the highest multi you get on your chip? I still have to turn off HT & try a few more things. The is also a new bios that just came out I need to upgrade to & try.

Now that you guys say that....Davey, check the options.

I have my amp probe out, I will check out what my entire rig is pulling & do the calculation for watts. P = V * I

The 2600K is rated at 95W Max TDP, the same as the Core i7-860. I know my i7-860 is probably drawing at least 200W out of the wall. If the 2600K were rated at 65W, a power draw of 150W at full load might be more believable.

[trn]

My westmeres at only 3.7GHz draw 175W headless, I'd believe 150W for SB without a ridiculous over clock.

[Movieman]

And we have a winner!
Yup, sorry guys, but it was on volts..
On watts at 4433 100% load it's showing 196W

oops. Now everyone can unwad their panties.

[Rob_B]

Maybe your little trick worked, Dave. How many here quickly bought a SB after reading about 50k PPD @ 120w?

[shoota]

edit: poop flew out of my mouth.

This new power consumption info has me thinking.. I've not seen hard power numbers for crunching at 5ghz (or the volts needed to get there) but if SB can crunch at 5ghz (or close) at under the watts the other i7's use then it's epicness will be restored in my eyes

[Movieman]

fail thread now lol

Still a beast of a machine for the money and will try defaults and check wattage draw then.

Hey! i edited that out haha.

I just saw where a 2600k was pulling 200W at load @5.1 ghz and a 930 @ 4.2 was using 230w (http://www.xtremesystems.org/forums/...d.php?t=264847)

I didn't read thoroughly enough to find vcores used.

Like you say MM a beast of a machine.

[[XC] 4X4N]

I don't believe that 230w figure either. I ran at 4.2 for months and was always between 260-265w.

[shoota]

did you have a video card, and fans and stuff? cuz that 230w figure was only for the board, cpu, and ram. so 260 for a full system might be about right

edit: my killawatt says 242w right now for my i7-950 @ 3.5

[OldChap]

Looks like I'll be doing another test this weekend....meter vs Kill a Watt clone. I have to say though I ran a pair of gx2's on a ud5 @ 3.0 (stock volts and cooler) for a total of 721watts (kill a watt)on my corsair tx750 with no problem so I do not expect it to be that far out

[[XC] 4X4N]

Yup, full system, I was getting about 35k a day from that. So if these produce 45k at 200w, that is pretty damn impressive.
