Conroe Rate of return at LOW TEMPS ?

[iboomalot]

Iam in the process of designing an extreme system and looking towards Conroe as the CPU.


I noticed that people can get very fast OC results from air/water and it seems Conroe has small gains as temps drop.


My question is: Is it worth spending the extra money on doing a cascade or autocascade -100c temps vs just a nice single stage -60c ???

This is for a 24/7 setup.

what increase should be seen in OC between -60 and -100c???

[Stelios]

Do you bench ? I mean , not once in a while ...

[iboomalot]

I usually bench to see limits of system but I don't compete on a level like the LN2 people.

I do alot of encoding and strategy testing (stock trading prog.) thus speed is important.

I fold and game serv so its important the machine run 24/7

------------------------------------------------------------

I was thinking of using a 3/4 hp panasonic rotary compressor for CPU and 1/2 hp rotary for a chilled liquid on the GPUs


THis system will have to last atleast 12-18 months and stay fast. My current 4400+ has been going strong for a year. just time to upgrade.

I think it isn't worth the money, beter buy yourself a X6800 and maby a single stage (you can alway's but one later)

running a cascade 24/7 also brings some isulation issues, and you will be sponsoring your electricity company to.

what is the system you are planning to buy so far?

wouldn't a liquid chiller for gpu and cpu be a better idea? I think you can run a more than 4 Ghz then whit an X6800

I wouldn't buy anything but an aircooler for 24/7 use.

A Hr-01 with the fan duct, a Scythe Ninja or if you don't mind a little noise the Tuniq tower with a potent Enermax fan or something. All these perform really nice.

Think green. Do you really need a expensive cooling setup that also adds to your electricity bill?

A 120mm fan eats just 1-2 watts or something.

E6700 + any SS unit if you want stupied speeds, 4+ GHZ are doable on phase

3.8/9GHZ on air which will still kick your AMD to bits.

Conore will hang about for ages

[iboomalot]

I currently have a water cooled storm block with 302 rad and MCP-655 pump.

I will be putting the computer in the garage and remote controlling it in my room.

I was looking at chilling the GPU with a rotary wia a flat plate HX then a SS or autocascade.

maybe a 3/4 hp chiller using 410 or 507 might do well

just wondering how much increase in CPU power chiller -20c vs SS -50c vs autocascade -100c

example purposes only:

air = 3.6 ghz
water = 3.8 ghz
chilled = 4ghz
SS = 4.3 ghz
cascade= 4.6 ghz
LN2 = 5ghz

what is typical OC with those different cooling systems?? your opinions??

[sierra_bound]

Some people run SS 24/7. Just be prepared for higher electricity bills. Running a cascade around the clock is unrealistic. And your power bill would likely be astronomical.

I think people need to be more realistic about their expectations regarding Conroe. Some may get 4GHz on air, while others may have to settle for a lot less. The results I've seen have been all over the map. Most of the results at XS are by benchers, running outside a case, with extra fans, etc. Only one person has managed to get a Conroe above 5GHz and that was TAM in Japan. Others may do the same, but I don't think it's as easy as some people seem to think. I've managed to get my E6700 up to 4270GHz with SS cooling. It may do more, especially with dry ice. But I haven't tried yet.

a 3/4HP-1HP single stage on average utility costs run 24.7 usually cost 13-20 dollars a month...not much IMO to run phase 24.7

I figured my local cost of 8.25 cents per KWhr

http://www.panasonic.com/industrial/appliance/pdf/cat2r8s3r126a-6f.pdf

520 watts * 24 *31/1000=386 KWhr * .0825 = $32.00 per month

[Supertim0r]

electricity is expensive in USA

[iboomalot]

system wise I was thinking the following

E6700 conroe
best OCing mobo
raptor Hard drive (already have)
2gb nice ram (not the 450.00 corsair)
two R600 based ATI video cards in CF

might do a SSD flash drive if prices drop below 700.00 at later date

[NickS]

LOL just calculated that and it'd cost me $11 more than you to run the same setup :p:.

It looks like the stepping 5 chips like's overclocking more and most of the overclocks are hold back by the motherboard.
If better motherboard come out witch will handle higher stable FSB the overclocks will be higher I think
