Wow thats an AWESOME prize!!! That may bring down the power grid!!! Special hats off to the54thvoid.
That's a little out of my budget, but what I've been looking at could mean more PPD for less $$$.
"how I install a 2.5" HDD into that hot-swappable 3.5" drive bay thingie for server blades?"
Currently my biggest blocker for running that server machine :/
Many company's make 2.5" to 3.5" adapters- do a search at your local suppliers for one. The metal adapter plate that ships with most SSD's is pretty simple, inexpensive, and will get the job done
aaaaaaaaaaand I ended up hooking it up w/out an adapter. So it's "don't touch anything or it will explode!"
BTW, running BOINC makes these CPUs shoot past critical temperature (go over 90°C), so they start to throttle. Thus, while I'm config'ing it, it won't be running BOINC.
Since I "installed" that server by just moving the HDDs from my 2nd FX-8320 machine, that one is offline, too. But, this doesn't mean that FX-8320 will stop crunching – oh no. I am going to upgrade/reassemble the computer I built for my father and thus going to replace the Athlon 64 X2 with it. The Athlon will then be retired until I find some use for it.
I had something weird happen last night. I notice my waterpump was getting loud so I went to check on it. I apparently had lost a good bit of water, not sure where as there were no signs. Air was going through my pump. So then I had to do some rig maintenance, which usually makes me happy just tinkering. I was not happy though, and this was a first. I got myself in a limbo set up with my lga 2011 rig on my desk now, watercooling and all. It sounds like there is air bubbles constantly going through the loop. I can not seem to get them out no matter what I do. I can't even find any air bubbles either.
Also thought of a really cool way to not use a case.
Use a sliding wall mount attached to my desk, like this, with a motherboard tray hanging off. Slide out and remove when needed.
Wow James, do you know where the water has gone too? That is crazy man.
BTW, forgot to notice: the HP disk controllers are f*cked up. It kept [logically] slicing off the last 32MiB (exectly 32MiB – 33,554,432 bytes) on every HDD I threw at it. Had quite some headache with that as due to that, any partiton that spans into that sliced-off area would no longer work. I kept trying a lot of things, but just couldn't reclaim those last 32MiB. When attached to a "regular" computer, those last 32 MiB would re-appear and everything would work again. In the end, I had a bright idea to resize (shrink) the last partition of every HDD I wanted to use on it by 32MiB. That solved it. Phew...
And @james888 that is one sick idea for a no-case! I love it!
Slow leak that dried. Didn't hit anything electronic. Seemed quick for natural loss.
Long story short, the LGA771 (2x1.6 GHz quad-core) server died and it got replaced by a Xeon E3-1230 v3 (3.33 GHz quad-core w/ hyper-threading). Power draw was 300w and now it is 150w. I'm not entirely sure how much more productive at BOINC it is but it definitely is more productive. I see it was enough to get me to #25 spot in TPU.
Sounds like it is essentially an i7-2600.
It's Haswell so it is more like a tiny-bit-slower Core i7-4770:
Here's a compare with one of the old processors:
Ah. I googled but not for the v3. I found the sandy version.
Hey guys, I have an older c2d e6300 that I have been looking for a cheap motherboard for. I think I found one on ebay. The pictures look good, but is untested and not guaranteed to work. It is cheap though.
Yea usually when they post "untested" it is an excuse to get rid of dead shit. I'll bet that sucker don't post.
I was thinking about doing a 771 to 775 mod soon to see if these lenovo boards I have would work with a 771 CPU. They are G40+ chipset so I am assuming it would work?
I saw someone post in a thread that they cut the tabs out of a 775 socket and could use a Xeon (S771) in it. Never heard of that before. If you need a S771 chip, let me know.
Go for it! Post it in the Mod Forum!! +1 for an Awesome Idea!!
If I had actually did this I would. Right now its an idea
My 2500k is at 4.4ghz compared to the 3.3ghz stock. That is a 4.4/3.3=1.33 33% overclock. If linux gives a ~25% boost, I think a 30% on my 2500k, but lets just say 25%... Then with linux on top of my overclock, I have the performance of a 4.4*1.25=5.5 5.5ghz or a 5.5/3.3=1.66 66% overclock. That is how that would work right?
It appears so if I use Ion's ppd estimator. I know my 2500k gets ~6000 points in windows at 4.4ghz and ~8k on linux at 4.4ghz. Using the ppd estimator for 4.4ghz and 5.5ghz gives me 6k and 8k.
The reason for this post, is HOW AWESOME IS AN EFFECTIVE 5.5ghz OVERCLOCK!!!?!
If I were to raise my overclock to 4.8ghz, which I can but don't do to needed volts, that would be an effective 6ghz overclock.
Now imagine if you put the time into setting up gentoo for a cruncher, which I have read would be ~10% performance boost. My 2500k at 4.4ghz would have 83% more performance over stock, an effective 6.05ghz overclock.
Maybe I should save a couple of $$$ and get an i5 for my next upgrade then.... was going to get a 2600k/3770k for my Z68 rig in a couple of months
I don't know how much of a difference hyper threading makes, but it doesn't seem like much.
To me, Hyper threading means I am running 4 WU's instead of two. Better, no? I am losing about .15 GHz of Turbo, by running 4 but, I believe it is worth it to run 4 at 2.4 than 2 at 2.55. Maybe, eventually, the 2.55 would catch up. But, meanwhile, with my frequent interruptions, i.e. bus rides twice/three times a day and the recent "no computer" at work crap...There goes about 50 hours a week crunching! So, when I am on, I want 4 queued up and running!!
I have cpu's with hyperthreading. My 2500k seems to do really well without hyperthreading. It just seems trivial.
From theoretical perspective: If a WU is built well enough to saturate the CPU's pipelines most of the time, HyperThreading can actually hurt performance.
Big thanks to the54thvoid.
Big thanks again for all this team is and what we do.
