Good, Cheap Cruncher?

[WhiteFireDragon]

You're lucky, especially if they are working 100% on Crunching. I don't know though, haven't used an ECS since the Socket A days.

I like Asrock for cheap reliable boards.

lol no, i did not crunch with them. i knew about ECS reputation, so i did not risk a cruncher with it. it was a daily pentium4 machine that lasted over 4 years until retirement. the other was from the athlon A, socket 462 days, lasted over 7 years until retirement.

I just realized that your i3 at 3.5GHz was churning out more PPD than my E8400 at 3.6GHz... by several thousand points.

That's pretty impressive (then again, I haven't been keeping track of the i3's/i5's).

Yeah, I was pleasantly surprised for an $85 chip.
It's also undervolted by 2 notches in bios.
I've never tried to push it but it runs very cool (stock heatsink no less) so I'd imagine it could do better.

My i7-860 on the other hand won't overclock at all.
Even bclck of 140 at stock volts isn't stable.
Does vastly better with turbo disabled of course but I'm not willing to do that since it works so well for daily use.

The i3s, if you didn't know, do not have turbo.
The dual-core i5s do but they're so much more expensive I'm not sure what Intel is thinking the market for them might be.

my little i3-530 about doubles the output of my e6600 at equal clocks. And the bugger will clock to 4.3-4.5 no problem... It's head first into a wall after that though.

According to my benchmarks, the oc'd i3 does 3 times e6600 in total FPU speed. I have been very impressed with this chip. I think I may get another - that deal above would be hard to beat. It also draws only about 150W from the wall fully loaded. If interested, I'll throw the killawatt back on it and get a more exact number.

You should overclock it further

[Sparky]

The ECS K7S5A was a decent office Socket A board, but it eventually died too

I've lost count of how many of those have died on family/friends/customers/random people that I've collected parts from. I only know of 1 that is somehow still running. I think the ECS guys were drunk and actually put it together right


BTW I wouldn't bundle biostar in the same group as ECS. I've had much fewer failures with Biostar.

Looks like it from your clocks

I'd be interested to know how close these i3s come to an i5-750 in point production.

[snoro]

well since the i3 are alot cooler than the i5 750, you can clock them higher and get very close to the i5 750 number while eating a lot less power and being cooler. My i5 750 at 4100mhz is doing around 20-24k ppd

That sure kicks the heck out of my Phenon II X4 965. Nice!

Wow, Snoro. How consistent is it? Got a snip?

Here's my 860 results (sig rig.) Not overclocked but seems to settle in on the 22x turbo multi (so 2.93) by its own accord when crunching.
Like the i3 I posted prior, it was deadheaded (RDC) and ran full out and uninterrupted for the entire SC week.

[Peen]

Would really like to see this i3... my W3520 only does like 35k a day at 4.4ghz 8 threads!

My i3-530 will only do ~17k clocked at 4.4gHz. It was very cheap though and very energy efficient (even at very high clocks). The difference in price for the total build from an equivalent i5-750 build though is only around $100. I don't know if this makes it a win over the 750. And especially not over a 1055T for crunching.

Note that the 17k is an estimate. It's not a dedicated cruncher - the host average plot looks like a rollercoaster.

Temps stay around 45-48C fully loaded with an old enzo saphire block on it.

I would like to throw in some low voltage memory, replace the current raid with 1 large wd green hd, replace the psu with one of those antec ecos, undervolt the pump, remove some fans and peripherals, and see if I could get the energy consumption down to 100W or less. That may make it a contender on the energy efficiency side.

I would like one of those. Looks like, with my estimate, it scales almost linearly.

4 threads 32nm clarksdale at 4.4gHz = ~17k
8 threads 45nm bloomfield at 4.4gHz = ~35k
(Is this consistent with Vapor's results? I don't know if he ever got any good clarksdale numbers)

I bet there's a bit of difference in heat, initial cost, and power usage.

Her is my daily output of my i5 750 on boinc 6.10.45 at 4100mhz. Just dont take in account the 8k wcg point day. Something went terribly wrong with boinc client that day.

Holy crap! How did you manage that?!?!

What projects are you running?

[snoro]

in the beginning it was every project, and now its only HFCC but even when i was running all project it was still scoring that much.

[Biker]

...Just dont take in account the 8k wcg point day. Something went terribly wrong with boinc client that day....

Yayy!

14.05.10 Boinc FAIL buddies

[snoro]

Well i messed up a bit with boinc setting to see if i could get better ppd and also solve a problem that i have now that i have some workunit that i have started but for some reason the calculation for them is stopped and its calculating other work unit so i tried to solve but i still havent found a solution for that.

[mezcal]

Thanks, Snoro. Impressive. Beating my stock 860!

Peen, my i3 results are posted earlier in the thread.

mezcal,

The average over your 8 posted days is 15,750 ppd.

What was the clock speed again? And was this dedicated?

[mezcal]

Moe, yes, dedicated. Did nothing but crunch for the week.
It is clocked a bit higher than my earlier (from memory) estimate.

Thanks for doing the math. It's Sunday

Damn, those are nice numbers.

[meanmoe]

looking at Vapors PPD chart:
(http://www.xtremesystems.org/forums/...8&postcount=61)

and snoro's results...

Mezcal's results suggest about the same as the bloomfield for the 860. I would put this at the best bang if they reliably overclocked. If I was going to buy a dedicated cruncher right now, I'd put best bang on the 1055T. Considering power consumption and having an extra gpu laying around, I would probably lean towards an i5-750 build.

Anybody got something better? (1055T is still hard to pass up)

[INFRNL]

congrats snoro; i don't know how this is even possible
this is more than my 920@4ghz. you don't run gpugrid at all do you?
i am now curious if gpu folding puts a decent hit on wcg.
i have always run both; so i have no idea. I do now my charts are like rollercoasters though. nothng like yours, yours are very consistent.

I may need to run a rig just on cpu to see what kind of results i get

I just don't get how a 750 w/o ht can keep up with or outperform an 860/920 with ht

[Sparky]

ATI GPU folding is going to create a little more of a dent on WCG as it uses more CPU power. nVidia, not so much.

[INFRNL]

snoro; what os and boinc version are you using?

sparky; thanks for the input. I still may have to try dedicated cpu only to see what happens.
