Posted 1232 days ago by Profile Ray_GTI-R
Currently testing an i7-2600K (Sandy Bridge), stock speed, stock cooler* & 50% CPU usage.
8 WU's running, it consumes 60watts less than my (very) old, similarly configured EE 3.4 P4, stock speed & 20% CPU usage, aftermarket cooler, running 2 WU's.
The i7 runs incredibly cool at those settings.
WU's complete much more quickly too!
* the i7 stock cooler looks puny but that's because the CPU is so efficient. Google a bit and you'll see how, on previous i7's, heatsinks got ridiculously big.
(I have no association with Intel other than as a retail customer.)

2.86 amps is 696 watts @ 240v ... you won't need to turn up the heating anytime soon unless you shift Massive amounts of air to the outside world

;-)

Assume the power bill is paid by the Bank of Mum & Dad :-))

My advise FWIW is to ditch them (sorry for being blunt), get a few 2-3 year old new/end-of-line laptops with, say T57xx CPUs & 3gb RAM each etc which will also cope with other projects that require massive RAM.

By my research three such items will draw 150 watts tops, more like 120 watts average and need little active external cooling. Active local cooling will reduce the wear & tear on the laptops' internal fans BTW.

With respect to all:- when dedicated people who have an extremely long history (10 years+ devoted to SETI) decide to post here for the first/second/fourth etc time _EVER_ in their membership ... there seems to be a fundamental problem that is not being addressed.

I agree with these members' views - please consider this a positive endorsement, guys 'n gals, of your considerable and patient SETI experience.

Perhaps a petition is in order?
34) Message boards : Number crunching : Cheapest way to Cool an AMD 630? (Message 1051432)
Posted 1342 days ago by Profile Ray_GTI-R
For, say 1mm plastic, think Qmax (google it): noise-free, electricity-free, burr-free, heat/melt-free, consistently precise every time pretty much indefinitely, for round, square or rectangular holes.
I've been using Qmax for about 40 years, wouldn't use anything else.
Also, it isn't limited to cutting plastic. Mild steel, aluminium, etc etc will get cut the same.
A little expensive, yes but a reliable, dependable long-term investment.

Posted 1342 days ago by Profile Ray_GTI-R
I've cut holes in plastic using a soldering iron. It might not work for all plastics, but you could try it on a small area that is due to be cut out anyway.

Never a good idea ... think toxins/carcinogens!

The cheapest solutions when using the existing cooler, in order of preference;-
Open a window (it's -2C here so that would be OK for a 20C drop!)
Open a window and a door (might not be a popular choice with family at -2C)
Put the PC on the floor (not on the desk)
Remove the PC cover (if the case is a constraint)
Underclock

After that, start spending money, in ascending order of cost;-
If you have one, use a simple mains fan (cost is only the excess electricity)
If you have one, use an airconditioner (cost is only the excess electricity)
Modify the case (if it is a constraint) to make it more efficient
Upgrade CPU cooler
and so on ...

(FWIW commercial server rooms move VAST amounts of air throug and exhaust VAST amounts of heat ... out of the server room.)

Missed doing the 10 year club. Managed to remember for 11 years.

Me too :-)

38) Message boards : Number crunching : beating noise coming from PSU (Message 1044260)
Posted 1372 days ago by Profile Ray_GTI-R
I just tilted the case 45 degrees and the noise went away

Definitely bearings.
Definitely RMA.

I've tested over 1,000 fans from 20x8mm to 120x25mm and every single one new.
1 in 100 (average) is bad for this very reason and I have tried everything from running-in, heat-stressing & re-oiling (waste of time on a new fan but I live in hope) to hitting with hammer (joke) ... a bad, new fan will always be bad.

HTH, Ray
FWIW RMA in the UK includes zero cost to buyer ... from reputable sellers ... as in "Not of merchantable quality".)
FWIW2 Worn-out is a whole different story, involving bearing type/nature of dirt ingress etc etc ... I've had some luck with this issue by re-oiling, obviously with a suitable lubricant for the bearing type.

OOOOOOOOHHHHH! LOADS of tasks.
Sorry for the stoopid post. I have no idea how the Task List was set to just "Show (only) active tasks".
Suggest restart/reboot should default to "Show all tasks"?
Most of my related threads/posts over the past couple of days are hereby defunct!

Posted 1383 days ago by Profile Ray_GTI-R
OK, this is completely weird.

Concerned that one PC was running out of work I did an "Update" ... paused for a while, altered the CPU priority to accelerate an existing task then ...

A new task appeared from nowhere.
When I checked "Properties" it appears that it had been downloaded 8 days ago. (I promise that task was not present in the past 8 days.)

Then a second task appeared from nowhere, same reported download date.

I have checked the current "Transfers" list and the "Messages" list ... neither shows any evidence of for download of these tasks within the past 5 hours.

What the **** [my asterisks]

Got 1 new task, OK, very shortly after the original message was posted. (Spooky, eh?)

TTFN, Ray

PS:- to re-phrase the reply ... it's OK for the project to send out misleading messages. Or did I get that wrong ...

Posted 1384 days ago by Profile Ray_GTI-R
The project isn't giving me any new tasks.
Tried repeatedly to get new WUs on 2 PCs.
Neither is in panic mode.
Neither has "no new tasks" set.
Both have 10-day WU cache set, currently containing about 2 days of work.
Both are happily crunching the couple of remaining WUs that each has left (I don't do 24/7 so always have something in reserve).
Messages ... all the usual stuff.
Now and then ..."Internet access OK - project servers may temporarily be down" (no servers were down over the past 4 hours). EH?
Most worrying is "Not reporting or requesting tasks".
This is despite the WWW server page showing "Results ready to send" declining as they are being sent out/increasing as tasks are created.

Is there a favoured participant setting?

Posted 1384 days ago by Profile Ray_GTI-R
it ran 24/7 without crashing/rebooting while BOINC was running the CPUs full tilt. If BOINC was closed the random reboots would start again.

This exact thing happened to me once, running SetiClassic. It turned out to be a CPU that was on the brink of failing.

Not sure if this zero-cost solution has been considered before ...

It seems clear that many Teams are associated with commercial interests.

Many commercial interests are simply testbeds and are given hardware for evaluation.

Ergo there must be much "stuff" out there that is:-

a) free
b) cutting-edge
c) hardly used
d) discarded after the next magazine issue etc, etc

Put another way ... heads-up to reality to prevent people spending money unnecessarily.

DIMMS


DIMMS ... is that really true?

That suggests RAM with a non-quad-bumped maximum FSB of 133mhz ... like I abandoned years along with my trusty P233MX after 25K hours on seti classic.
I think I still have that RAM stick, yep, it's a 512K module. I'll donate it if seti is that desperate.

Mostly all OK now, from a me-perpective. Got new tasks, reported completed tasks and stats are updated.
(As of about 40 minutes ago.)

We now have over 4TB of space for uploads! Not that we'd ever use that much.


Hands up who has heard a similar story before? I remember a friend buying a 170mb hard disk for about the same sort of price that 4TB now costs saying pretty much the same thing. Expectation counts for nought ...

Anyway, it seems that servers are gradually (in the past few minutes) being brought back up. I got new tasks about 36 minutes ago. Pause for deafening applause!

For more information, check the Technical News link on the home page, please.

That's 5 days old news (with ultimate respect to any organiser of the fund drive, the SETI project et al).

The great info provided by Donald L. Johnson should really be on the SETI@HOME front page, permanently. It may be common knowledge to old hands on this project ... but newbies need this up front in order to ''manage expectations''. And it would cut down on the 000's of DUH questions hereabouts recently and historically.

Still and all ... >9 days now.

Posted 1401 days ago by Profile Ray_GTI-R
After careful consideration I joined Orbit as a backup given ...

JOKINGLY

that:-

a) SETI can't currently deliver on any level (harsh I know - but check my SETI ''joined date'' and ask me why ... at your peril ;-)
b) I'd rather know about my death 1 second before it happens instead of a WOW! 100 years later
c) If ET is really out there, SETI won't hear the reply for 11 years ... minimum ... via SETI current status.
