Nehalem,One cpu to rule them all!

Thanks for the info Dave. Just what I was looking for.

Obviously now the choice is do I upgrade my gaming rig (I think so!!) or get a couple of Quads to add to the farm?

P35 gear might be getting cheaper soon!!!!:up::up:

I was having the same problem with one of mine that was doing only HCC work. I switched it to HPF2 and am doing much better. Some machines just get better returns on different projects.

For example:
Attachment 88452
This machine (name blocked out as I was rather cross when I named it) was getting about HALF it's claimed credit on all HCC units. Since switching to HPF2 it's getting a LOT better return.

My Opty systems on the other hand:
Attachment 88456
do quite nicely on HCC work.

Only that I don't care about points, I care about how much HCC WUs per day are computed by my machines. If they decide to rate down the Harpers that badly it sucks, but it sure as hell doesn't stop me from crunching HCC.

That's fair enough, but it's not just the Harpers. Those stats I posted first are from an Athlon XP machine. I haven't noticed a real reason for this disparity across different hardware yet, either.

Just for clarification of my standpoint, I am constantly torn between running exclusively running HCC (personal reasons not unlike anyone else's here) and mixing the projects up with other valuable work that gets a better return for my team and which achieves the same goal albeit indirectly. I tend to vacillate between both strategies but always have mostly HCC work. As such I cannot and will not criticise anyone for running whatever project they feel better meets their needs/situation. I only offer the kind of comparisons I made before for those to whom the work selection is less personal.
It's all good.

smoken folding !!

the worlds gonna be in better shape quickly now :up:

Sure, and your views and insights are very much appreciated.
I didn't mean to imply anything on your behalf with my last post, just stating my POV. Getting less points than deserved does bug me, after all - even if it's not the deciding factor here.

No problems ;)

No matter how many smilies we might use, there's no substitute for a friendly tone in conversation. :D (I get accused of things a lot when no issue is intended)

Don't forget f@h ;)

If you can beat my Dual Harpertown machine with one Bloomfield, I'll buy the 3200EE ;)

it's only ranked #5 in dailies out of 540000 rigs on WCG :hrhr:

jcool: wait for Dave to put it under water. It's already most of the way to Harpers. He said 4GHz should match his old Harpers, so let's see about 4.5 or 5ghz. :p:

You know, with the way these things are running, I might need to add in another loop just for the CPU and see how high I can get an i920 screaming ;) One MCR320 for CPU + NB ('sif WC the SB) + Mosfets and another MCR320 for 2x HD4870 1Gb's with those new Swiftech MCW60-4870 partial cover blocks... Damn, I need some money, and stat!

Eller

My new Core i7 System (i920 / P6T Deluxe / 3x 1GB Corsair) have to come in a few day's, then I'm back with crunching. :toast:

He's saying a lot these days.. but what I still see is 4:25h vs. 2:44h for 8 WUs...
No sub-5Ghz Bloomfield is gonna close that gap anytime soon, and even then I doubt it can be done (I'm gonna try myself ofc, phase + 3200EE FTW :wasntme: )

Where is he anyway? Waiting for him to verbally slaughter me :rofl: :rolleyes:

Nice to see someone else from Germany chiming in :up:

Any word on what this pulls out of the wall for wattage yet?

While I'm at it....maybe we could start a thread/database of hardware, clocks, and power draw. I know 45nm is more efficient than 65nm....but by how much? Is it worth it for me to replace a Q6600 with a Q9650? Will it pay for itself in a year or two or three at my current electric rate? All rhetorical questions - with such a database, we could do the math and answer these questions for ourselves.

Anyone know of such a database already in existence? I'm sure this isn't an original idea of mine....especially among crunchers/folders.

Maybe I'll post this separately:shrug:....sorry for the off topic.

Wait....didn't riptide do something with excel somewhere on here?

.....off to find that thread

No, you are right. There is no common sense to the claims involved for the timeframe taken EXCEPT I think it's claiming based on using an entire core or two for the benchmark.
That is the issue and it's leveled out claiming at a rate of app 33,477 per day and being awarded at a rate of app 25,339 per day based on the last 10 days.
This is at 3733mhz on air and almost 24/7 crunching.
A little time taken during these 10 days for the occasional bench but not much time lost.
This is all on the HCC project.
OOPS, forgot..Factor in another TWO FULL pages of WU pending validation...:wasntme:

So it looks like the benchmarks with HT on are ... dubious. How do the claims average out based on actual working time as opposed to wall clock time?

If you don't know what I mean just grab me a full page of valid work with crunch time, claimed and awarded points and I'll work it out myself.

What I can guess is that the BOINC Benchmark only stresses four cores for the test, or perhaps the workload assigned to the benchmark doesn't keep the low level caches very busy, whereas the workunits themselves are more complicated and cache/ram stressful, thus making the difference between four and eight threads sucking bandwidth from the L's much more tangible in the "real world" scenario as opposed to the benchmark scenario.

Just a congecture.

Yes, that looks to be about right. Still impressive. Means a single Bloomfield could do 30k+ under water if pushed far enough.

Which would make a Dual Gainsy a 60K/d monster.. which would make it 25-30% faster than my fastest Harper. Yummie :hrhr:

PS: Good to have you back Dave :up:

That will be my next and last system for a while.
I figure a dual Gainstown, a Bloomfield, 2 harpers, the Q6600 and sammy split up between my and Mesh's accounts wil be it.
The clovers are going.
The bunch should do close to 170K a day.

Sounds similar to what I am up to. 2nd Harper is waiting for the mobo to arrive (finally...), so that leaves me with 2 Harpers, Q6600, E8300 (thanks again Dave :D ), Sammy and the Bloomfield and/or Gainstown to come :up:

This is what the BOINC benchmark looks like in the task manager on my QX9650. It runs a short burst on all 4 cores and then another short burst on core 0. I'd be curious as to what it does on an I7 with HT enabled. I had a feeling this issue of "overclaiming" would come up with I7 since the BOINC benchmark is not set up to deal with virtual cores.

Have you tested the rig with any of the single redundancy projects like FAAH Dave? IIRC points are claimed and awarded via a small benchmark run within each work unit. I would think the claim/award ratio would be much better if the bench is run with all 8 cores crunching.

Just been running the HCC project due to preference and continuity on the numbers so I'd get a decent "feel" for what the machine is doing.
The benchmarks between HT enabled and disabled are very small.. maybe 100-150 difference..
The key to see what the real power is when you disable HT and run 4 WU.
It does those in app 2 hours 25 minutes.
That's at 3733mhz.
My Q6600 at 3600 does the same WU in just under 3 hours, like 2 hours 57 minutes..
With HT enabled it does 8WU in 4 hours 20-25 minutes but I think it is working "harder" as temps between HT enabled are a solid 6C higher..

Oops, I forgot to upload the screenshot...lol! It's up there now. When you run the benchmark with HT enabled, does it load up all 8 cores during the initial burst, or only the 4 real cores?

Well it does load up all 8 cores on a Harpertown.. if only for seconds.

And they still run today, now that was quality hardware.

You wanna talk about shooting the wallet.

I dont think ive been so poor since my freshman year in college. :\

Hera is seriously killing me financially.

I think i understand what you old ST people went though, and why you wanted to sell it at one point in time.

The financial commitment for one of these monster classes, is just outragous.

Get into modding, and then wonder why you're broke. Why else do we seek sponsors so often? That money tree in the backyard is misleading, I haven't gotten any money from it yet. Just these funny white seed pods.

koolancedean said he would sponsor my ST II rig with 2 koolance blocks.
Ima throw it on to make them happy, if they perform great, keep them, if there on par, keep them, if they have a hugh performance cut, then recycle them on my sossoman setup. :up:

Bei Fei is commited in making me my STII board blocks.
Extra Hardware already bought. I am even tempted to throw both a HD4870X2 AND 9800GX2 on the same board and run each monitor off each card.



Other then that, dude, the hardware cost is killing me.
My chiller is still being built and i havent finished paying for that even, let alone the st2 board. if and when i can get one. :\

Dont know what kills me more, having chips and no board, or not having anything at all.. or holding a nda and not being allowed to speak of anything at all.

Been in all 3 situations and they all SUCK!

Seriously water is the way to go with these. They run hotter than the 45nm Yorkies and need the added edge of water cooling.
I think 4000 for 24/7 work is possible with water and as soon as I can afford the parts I'm going that way.

It will, but I think a simple water cooling system will handle all your needs.
look at it this way;At the same speed the nehalem runs app 10C hotter than the Q6600 fromk what I see at least on WCG.
Since they are in the same house(envirionment) this is a fair comparision:
My Q6600 at 3600 runs at 51C at 100% load
The Nehalem just 30 ft away on the same floor in the same temps(maybe 1-2F higher as it's in the office and thats a smaller room with just one door, runs at 61C at 3733mhz
A little faster but the 10C difference is a damned close one to use for comparision.
Also usefull is that even when I benched it at 4226mhz the temps never went over 65C so I think with water 4000 for 24/7 work at a temp in the 50's is very doable.

To Bowman:
I don't know what your using for cooling but those temps would scare me.

Yeah well, I'm shooting for 4,8-5Ghz 24/7 WCG stable on a 965EE. Something you probably can't do on water.
10C higher temp is fine with me, approx. Coretemps of my Q6600 are around -15 loaded, so -5 is fine with me.

Sadly the sensors don't work below a certain value, so my readout stays the same whether it's idle or load :shrug:

You won't get that on the nehalem.
4000 is doable, maybe 4400 under phase for 24/7 work but not 5GHz..
There just isn't the difference between water and phase that we saw with the Yorkfields..Do some reading and you'll see what I mean.
save that setup for a yorkie and do the Nehalem on water..;)

I'm using the stock heatsink with the silly little patch of stock paste that comes slapped on it.

No, I can't be bothered doing anything about it until that damn TRUE adapter finally arrives in stock somewhere.. Christ, the socket dimensions and the need for one has been known since, what, October last year? Why couldn't they have ordered a supply awaiting the release? Oh no, gotta wait half a month after the release.. Makes sense.. :mad:

You're not telling me 4,4 will be max here, are you?!
That means I'd have to get to 4,5Ghz at the very least :p: This is so on Dave.. :D

:banana::banana::banana::banana:ty mount with old waterblock but it should work. My waterblock has a plate to push it down and it has a lot of holes and 2 of them work but the screws have to be a bit loose so they are not entirely vertical.

In the meantime I'm gonna look to build some better mounting. Not much blocks available huh and I don't wonna use the stock cooler.

I'm gonna run it like this for a night and tomorrow it's tweakin time :D

Got myself a testing setup to see whether i7 is ready yet to make it into builds for my customers. i7 940, GA-EX58-Extreme, 3x2GB Compustocx DDR3-1600 low voltage sticks (actually I have 2 different sets with different chips, gonna try which one's better), 2x Compustocx 64GB SSD.
All parts slapped on the table for now, using air cooling (Noctua U12P with 2x P12 fans) I got the chip to run primestable at 4Ghz using 1,386V Vcore (well, 1 hour SmallFFT so it should be rather stable). This is a mediocre result for a 940 I was told, I hoped to achieve 4Ghz with less vcore but still... Passed 1 hour of prime blend as well, BCLK of 182 seems to be pretty easy on the setup, as I only had to raise QPI VTT and ICH Core by 0,1V.

Bios still has a few bugs, but overall it's working great and the performance at 4Ghz is really impressive. Gonna be watercooled of course.. temps are in the 75C range during prime, a tad too high for my taste.

Go for it guys!

Effectiveness of i7 HT on WCG projects other than HCC - ?

Over at WCG, http://www.worldcommunitygrid.org/forums/wcg/viewthread?thread=22295#192664, Community Advisor JmBoullier recently posted results of some experiments with HT on his 2.4 GHz P4, running HCC. He found a large throughput increase with HT.
Conventional wisdom was/is that on P4s, HT gives worse performance on WCG. Perhaps that only applies to projects other than HCC. He suggested that HT on the P4 may be so effective on HCC because HCC uses mainly integer calculations, while other projects use more floating-point.

MovieMan: Before lots of people who crunch projects other than HCC rush out and buy i7s, could you please try out the effect of the i7's HT on projects other than HCC, currently FAAH, HPF2 and NRW? No disappointments, I hope.
(Because of the variability of the length of FAAH WUs, the best way of comparing crunch speeds would be on points awarded per hour, after eliminating the WUs that had a quorum greater than 1. An average of about 10 WUs would do ... I suspect a bias of more pts/hr for longer WUs tho. Or do my data-snapshot + rerun-same-WUs trick as per Post #63 above.)
PS: I did some testing of XP-32 vs XP-64 on WCG projects, and have updated my previous post, #63 above http://www.xtremesystems.org/forums/...5&postcount=63. - Rick.
[Update, 16 Dec 08] Over at WCG, BE04642 in thread http://www.worldcommunitygrid.org/fo...ffset=0#195901 posted some data re HT with WCG on his P4s. He says that running a FP-intensive project like FAAH with an int-intensive one like HCC or Rice in the other thread works well. You'd have to do a lot of manual assignment of core affinities to achieve best pairing of WUs on an i7 quad tho. Mods to BOINC are needed.

He may well be right. I've been on the HCC project solid so I've done very few other WU since.
I'll take a look and see if any have gone thru and get back to you.

Lookie lookie what was in the mail today:yepp:

Sorry for the tease but for some reason it actually felt good to hurt the cc:p:

Whohaa nice . How high does it clock ? :rofl:

dunno yet, still waiting on mainboard to arrive.

For the people with Asus P6T boards : watch out for 'AUTO' settings and overclocking !!
If you leave everything on auto and start pushing the BCLK , the voltages raise automatically . I've caught my DRAM voltage at 1.66vdimm (:shakes:) , QPI/DRAM 1.3v , PLL voltage also very high IIRC.
There's a nice tool called 'turboV' , that's how I noticed.

Best to set these voltages manually before starting overclocking !
It's pretty difficult and confusing when you're new to core i7. But don't worry , here to help :)

That is, unfortunately, a bad habit that nearly all Asus boards have. I've caught both my P5E and my P5K Deluxe doing that.

My words exactly, that's what I always warn people about. Sadly, hardly anyone listens to me, they all love their asus "auto oc" mobos :rolleyes:

Even though these values are still quite harmless, especially compared to certain S775 mobos using 1,6V+ VTT on 45nm parts when left on auto :shakes:

jcool , I should mention i was doing very mild overclocks !! only 155 BCLK !!
Don't want to see what happens when you try 200 BCLK with everything on 'auto':eek:

Yeah it prolly goes to 1,7V QPI and 2V Vdimm at 200 BCLK :D

Gonna start crunching part-time with new hardware :) Core i7 @ 4,2 ghz and HT ON :D a real upgrade from an E6700 @ 3,4 hehe

client benchmark says:

Number of CPUs: 8
4002 floating point MIPS
10162 integers MIPS

http://img44.imagevenue.com/loc824/t..._122_824lo.jpg

Finally got my Watercooling back together, after a few minutes I had the above, voltage scaling seems a bit odd with I7, up to around 4 I had to bump it up pretty much linear, above 4 it needs volts like madness.

Yeah I noticed that as well, in fact most i7 CPUs seem to run 3,8 with very low volts but require a lot more to run 4ghz stable. tjelaw seems to have a very good CPU.

I don't see what is so odd with needing large jumps in voltage past a certain point.

While it's not really odd, it is not what we are used to since C2D was just too easy to oc.

I only have one question for you.........Does it Feel Smoother?:ROTF::D

When inserting it into the Socket I didn't hear any grinding noises, so it is pretty smooth, however, obtaining exact smoothness measurements is almost impossible though and your mileage may vary:rofl:

Being 'smooth' is a Phenom feature.
Bloomfield is the opposite , raw brutal power :rofl:

Good article on Anand about i7 overclocking.
