It's still early but it looks like the new rig will top out at around 26k ppd. It might get a tad higher but it's doubtful that it will hit 30k on a regular basis. As prices come down, I might look into getting a pair of 18 core chips but these are still very expensive.

I made up a chart to estimate ppd based on points per ghz per core and the estimate I came up with for the 2.3ghz 14c was just under 27k ppd. So it looks like my estimate was pretty much on target. I took the average ppd for the dual octo core rig with v1 chips and divided by cores x ghz to get a base figure of 645 point per core per ghz.

I used that as the multiplier for other chips (taking cores x ghz) to get a total output figure. Then I multiplied that by 1.3 to reflect the roughly 30% increase in efficiency with the v3 chips.

According to those calculations, 2 18c chips at 2ghz should produce about 30k ppd total. 2 at 2.3ghz should produce about 34.5k ppd.

Ok, but, how many matches does it take to light a fire on a windy day. I need solid averages, can't afford to waste matches. I want wind speed averages from 10-25 miles an hour, because anyone can light a fire in sub 10mph wind.

Oh and, wood matches are at least 1.3 % better than matchbook-ers.

Sorry, @twilyth , you sometimes amuse me with your intensely random research!!

And by "Amuse Me," I mean envious of your concentration to a subject. I am mostly scatter-brained, with short periods of focus.

I have to try, real hard, to care about something for more than an hour.

 

[twilyth]

It's mainly a matter of self-interest. You don't want to spend a couple grand on something and not get the results you want. The only research that was involved was trolling through the boinc host stats to find whatever other v3 Xeons were already on the network. You just sort by credit/day and all of the big guns will bubble to the top. From there, you just have to calculate the ppd/ghz-core for a few machines to get an idea of how much more efficient the v3's are over the v1's.

As @Knoxx29 pointed out in one of these threads, having a lot of cores at low ghz doesn't really help you. You want both speed and lots of cores. The only exception to that is if you can get a chip with greater efficiency. Once I figured that the v3's were about 30% more efficient, that seemed like enough of an increase to warrant a new purchase.

+1 that, clock speeds really make the difference. Lots of cores, as well. And the proof is right there in the scores your new setup is getting!

 

[Arjai]

It's OK, no need to defend yourself.

I get it, with cores and speed. That's why I up-ed my Karen machine from a Q6600 to an E8600, more speed less watts.

Plus I got one off E-Bay for a song!

I did the same thing with my P4, went from a 2.0 to a 2.8 for practically nothing! Got from some Chinese outlet, took 5 weeks tp get it but, it was worth every penny of the $10, or so, I got it for. BTW, damn thing is like a ROCK!! It sat in a storage locker for 2+ years, and I plugged it in and away it went!!

Granted, it doesn't give me more than 600 ppd but for a total price of 10 bucks invested, I like it. Also, it was my first kiss with Linux. So, it has been a good little box!!

For me, anyway!

 

[twilyth]

Yeah, ebay is a pretty good resource. It beats trying to keep track of all of the various fs threads on different forums. You just have to make sure you know who you're dealing with. A lot of Chinese vendors sell your email address if you communicate with them directly so I do everything through ebay. I still get tons of spam at one of my addresses I used to directly communicate with someone and that was several years ago.

BTW, I checked and it seems that the 4P v3 chips only started coming out in May, so maybe that's why I haven't seen any. If that changes and I can find enough matched chips, I'd consider going 4P.

 

[Norton]

Those sound like great #'s @twilyth !

My 4P Opteron rig (48 cores) will do 20-22k in Linux for around 550w so you're around 30-40% over what I can do in the ppd/watt range.

I do have one suggestion for you to try if you're going to go with another 2P rig- try going with a pair of higher clocked 6c/12t chips. It's a fair bet imho that you will get close to 90% of your current output from the 14c/28t chips for less $$$

 

[FireFox]

Lots of cores

+1 there are a lot of Cores, but i still insist there is not enough Clock speeds.

according to my estimates, a dual 6 core v3 rig running at a base freq of 3.3ghz should produce 16.6k ppd. An 8 core dual v3 should produce 22.1k ppd. There might be more of an advantage if the turbo mode is higher with all cores being used.

I like the idea of having a lot of cores though for badge hunting. I'd like to be able to get to the point where I can produce a full year's worth of work in under 2 days. Right now I think I'm at about 2.5 days.

GHz are lower with these extremely powerful CPUs, like a big engine running at slower RPM, while having enormous torque. I believe this has been mentioned earlier. @twilyth is now "driving" one of those new "V56" engines, luxury style. And it looks like its "fuel" efficiency is great!

Half a day to go!

 

[twilyth]

LOL, that's pretty funny. I hadn't really made the association between the version number and a v-engine, but I like that. It reminded me that some of the most powerful engines have a w configurations - like the Bugatti Veyron engine.

Along those lines (long way to for a segue, I grant you ) I was looking at the boinc host stats and a 2687w v3 produces some very nice numbers. Running at a base of 3.1ghz with 10 cores each, the v3 should be able to produce about the same ppd as the 14c running at a base of 2.3 ghz.

So is anyone else having some issues getting new WUs, particularly OET? I noticed a little bit ago that my queue was shrinking, and now i'm only running 4 WU's, all CEP2; the only other project was OET.

Not sure what's going on, but I don't like it

Edit: just checked the other rig running and it's drying up too.

Edit 2: just checked WCG and apparently it's not just me, others are not getting OET work.

Checked the rig I have running at home and it seems to have plenty of work (MCM, OET, an UGM wu's waiting to go)?

Will check shortly to see when the last one was sent... it may just be working through what's in the cache atm.

I have 20 OET's between my three boxes. They all downloaded this morning.

Thanks. I should mention my buffer is awfully low anyway, so it goes through it quickly.

I added in other projects and the 2600k dl'd some UGM immediately and added to the queue, while the 4770k didn't dl anything new. I just need to wait and see what's going on

Aye... It seems my last ones were from this morning maybe around 8-9am. Not sure what's up. Gotta wait but thanks for sharing with me, makes me more confused lol

Have another drink, it will all clear up.

Yeah... That sounds good



Edit: got some more work dl'd, though not any OET. But it's all good, I'll take it

 

[t_ski]

I was having a really hard time with OET trying to get my 5y Diamond. Buffer kept running low once or twice a week. Got the diamond and went with more projects and numbers have evened out (well, at least until CEP2 hit me and I scaled back my allowed WUs).

Another bad news.
D425 died. doesn't seem to power up. changed the PSU, but no power.

This year seems to be very bad for my computer hardware.
Lost a 990FX board , Corsair PSU(still in RMA), 2 seagate HDD, i7 2600 processor and now D425.

no more hardware this year.

Very sorry to hear about your troubles... However, if it makes you feel any better - you are not alone! I managed to kill a Radeon 290X last weekend - as well as 2 boards in the last 4 months. Also, one stick of RAM and 1 HDD. RIP, all of you. You just have to accept stuff like that sometimes, and move on even more dedicated! I wish you the best of luck for the future.

Note: now they are in a better place

In the trashcan - is that really a better place?

Who wants a 780ti Classified?

Seriously - I've got a new card incoming (and I'm stoked, it's a 980ti Kingpin) and as long as it's all working and whatnot, Both my Classy's will have new homes. Unfortunately they're not free - postage will be required, but that's it. So UK to overseas is about 40-50 quid or dollars or whatever. I'll pop it on the FS thread but one of the two will be limited to the crunchers and folders. I've always admired your selfless ways (may Richard Dawkins bless you) and my way of folding/crunching is by donating. This card goes in Kreij's honour.

If any of you have a novel way to suggest a good owner, I'm happy to liaise with @Norton over it but obviously the postage cost makes it a 'not' freebie (but close enough).

Both cards are hydrocopper water blocked but one was modded so it still has a reference cooler.

I'll need to get my new card in first so let's not rush!

I'm still in the hunt for a 780ti. Would gladly pay shipping and put my EK 4GB 680 up for grabs FF as well.

Well, I have two but I think there may be more than two requests! I do like the pass it on idea @theonedub, it's what a community is about.

But I'll await the wisdom of folksies like @Norton to guide me through these 'giveaways'.

EDIT: maybe we create a stupifyingly extravagant hand me down chain....
