SETI@home News Vol. 119 (09/01/2011)

Well, I got a bit sidetracked on the Wee Rig and Mid Rig......

Swapped Wee Rig into a little bit bigger case, installed an i7 860, new Thermaltake Frio Cooler arriving tommorrow and put my two GTX470's in it for now. Everything seems stable - but dropped cpu down to 3.7GHz (yet again - due to temp issues).

Gonna lap the cooler & cpu tommorrow - hopefully with this and some new fans I should be able to get a hold of the temps and whack it back upto 4.2GHz.

As for Mid Rig - it's going to take up residence in Wee Rigs old case and be sold on. Should get a reasonable price for it (fingers crossed).

With money from the following sales:

i5 650, 3 x GTX460's & Mid Rig - I should hopefully be able to WC Big Rig's CPU and make a start on some new GPU's.

However, this all depends on whether or not I get sidetracked again - try really hard not to press the buy button on a new 2600k with an ASUS Maximus IV........must resist.

:D

Once I start WCing big rig I shall be posting piccies - hopefully, sooner rather than later.
 
I'm afraid I've been slacking a bit over the weekend, weebeastie been offline since Friday, and Mars has had a heart transplant which has been challenging to overclock to say the least. But Mars is back up 4.4Ghz stable @ 55°C :eek:

Don't seem to be able to find the right combo to push it harder than that at the mo, you can really only overclock by multi on these things and even looking at the BCLK locks it during boot. So I'm at 100x44 with everything on auto.

Might one ask which sandybridge you opted for Mars Mr Biffa sah?
Either way i am sure you will be upto full capacity in no time. MMods dispatched today hurrah, but as a mate rightly pointed out “your a bloody lunatic, for what that setup is going to cost you’d be better off with 2 x sandybridge and 6 gtx 580 for the same price”, which did kindof gut me a bit but he is right :(

Yeah, but you knew that, with this rig, your output will go down as you will be using less gpu's.
BUT - you will be doing something different, it will be unique and kudos to you for that...

T what are you building it for? Thats what I tried to get out of you before you started. If you are building a Seti monster then yes the sr-2 is a waste as gpus spank cpus for RAC.

But for Folding its the opposite, gpus are a waste of leccy compared to cpus and produce far less PPD and you would have to go for one of BaBa's quad opteron unobtanium machines to beat the output of a well configured SR-2.

And mixing the two ideas on one system does help either. The GPUs and CPUs rob each other of resouces and interrupts such that output is noticeably affected. I'm not saying you dont get more output with a gpu/cpu hybrid system, you do but the increase is nowhere near optimal or linear.

I know remember? I have both a 6 core i7 970 with 4 Fermis, a SB with one Fermi and a standalone 80% optimized cpu only SR-2.

You would think weebeastie would push out:
50K PPD on the cpu
16K x 4 = 64K ppd on the gpus.
Totalling 114K PPD for the rig

But thats not what you get. You end up with just over 90K because of the hardware contention.

Compared to Gemini which punches out 130-140K PPD with no GPUs

Plus you are talking 1 gpu >= 1cpu in terms of power consumption. So the gpu rig eats around a Kw of juice and the sr-2 just over half that.

The situation doesnt channge if you run FAH on the cpus and SAH on the gpus. In fact the seti gpu app is less amenable to sharing than the FAH gpu app so performance suffers even more.

Oh i got the cheapest I could at the time: a 2600K and Gigabyte P67A-UD3

Morning Mr Edge, ta for that i guess i was having a weak moment :o

Hows the hunt going for something to fill that spare slot going?:)

Nowhere fast at the moment - I have been getting 1 BSOD a day for the last week, so am trying to track down the cause of that before adding more hardware..

OK OK you win :p

But theres a problem, you have just exposed an entire alien nation, they wont be pleased cos they were hiding.
That feeling in your pants your mentioned in the other thread has just moved to the rear :p :D

Initially it was greed, 2 sr2 setups one no gpus for folding the other 4 x gtx 570 and could work on that one too as it did not seem to effect it too much.

Then the reality of cost started to sink in, the case and the $460 for the 2 trays and back panel added upto a grand i did not budget for. Not too fussed if i dont use the 2 sr2 trays as theyre backwards compatable so once i get my finances in order i can go ahead with no 2 as and when and the case will be ready for it. Then as my m8 pointed out why not forget the sr2 idea alltogether get 2 SB 6 x 580 do seti on the gpu and cpu's for fah but as you have rightly said one would not be good for the other.

So thats where i'm at right now....still confuddled but looking on the bright side i have the 4 x triple rads and wc stuff which i am definately going to do.

Forgetting the fact i allready have the sr2 and cpu's and an i7 r3 470's etc if it was you and your main priority was seti, but you also wanted to fold on a regular basis what would you opt for ?

I don't mind if people want to chip in with whatever they think, criticism or otherwise it all helps as long as i get to do my plumbing its all good :D

Thanks for taking the time to read it peeps, and medication is not an option i allready do that ta :D
 
I'd throw the R3 & 470's at Seti and the SR2 at folding if it was me. Depends on what cpu you have in the R3
 
Had a good sleep on things and feel better about it all today. Now all i need to do is wait untill the 25th for the new 560's and see what effect they might have on pricing, hopefully they will show the 570's and 580's to be over priced and they will come down a little :)
 
Hmmm - this is not good, my main rig has decided to start bluescreening twice a day :mad:
Reboots itself, and my output has crashed, 26K yesterday and 14K today.

I have the dmp file, is there a good way to interpret the output?
I have run the driver verifier tool and it came back with no errors..

W7 goes online to check for a solution, but doesn't come back with any information, and the event logs have a kernel-power error, but I think that is more to do with the unexpected shutdown..
Time for some detective work..

edit

The computer has rebooted from a bugcheck. The bugcheck was: 0x000000d1 (0x0000000000000058, 0x000000000000000b, 0x0000000000000000, 0xfffff880043854c6). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 011811-17440-01.

Looks like I have a bug that needs squashing...

0x124 = add / remove vcore or qpi / vtt voltage
0x101 = add more vcore
0x50 = ram timing / frequency add more vcore
0x1e = add more vcore
0xd1 = add qpi / vtt voltage
0x9c = qpi / vtt likely but increasing vcore has sometimes curred this.
0x109 = add ddr3 voltage
0x0a = add qpi / vtt voltage.

Interesting - cheers Biffa for that...
Where did you get that info from?

Off into the BIOS I go :D
 
Evening All...........

My SETI capabilities will be non existent as of this time next week.

This is due to ALL of my GPU's making their way to the Bay of E. Already had an offer of £300 for the two 470's. Not bad me thinks - but I'm looking for a little more to cover postage and leave me with £300. The 460's (Gigabye OC's) are slowly making their way up the bid ladder as is the i5 650.

With the proceeds from this I am hoping to make headways into wc'ing my RE3 - CPU & MB only to start with. See how the temps settle with minimal heat from other sources i.e. GPU's.

With whats left I may partake in a little side project :D

Been looking the the new Sabretooth - any thoughts on how it will perfom with two 590's (when released)?
