I just found the 980X for $999.00 from microcenter. Only problem is in store pick up only. Stinks. I looked at parts to build a 980X system and looks to be around 3 to 4 grand depending on quality parts. Movieman did a review on a system from supermicro that is tempting but you can't tweek it. Under 1500. Just add chips, memory, HD and video card. Fits 5500 and 5600 series xeons. After reading power consumption for these new systems, Will definately be building one in the near future. Trying to sell my octo harpertown to raise the cash to do it. Thanks for your help.

Hypernova, for your needs an i7 980X is the one to get, rather than messing about with a dual socket system.
Ideally you would be using water cooling; £110 to £150 for a water pump system instead of a £50 heatsink and fan is worth it for overclocking, but if you dont have the space you just cant do that. Im scrimping for a Fermi, but thats just me. |

Movieman, I registered at Xtreme Systems under EtaCarinae yesterday but still not possible to post, same as Bearcat. I totally missed this the other day, so short a post I went right over it, sorry. I just checked your account and it looks ok. Any issues let me know here in bold print so I don't miss it! |

Would think the xeon would have a longer shelf life running 24/7 but am unsure. On the supermicro system you just reviewed, can that run with one processor only? Bearcat, you do not have to use 2 CPUs on a dual socket system, you could use one, but that would defeat the purpose of getting an expensive dual socket motherboard - unless you planned to upgrade in the future. Server cores are usually more reliable, but for crunchers it is better to upgrade regularly than to buy for the long term - a top Xeon might last 10 years but after about 3 or 4 years it will start age compared to future top systems. For most people it is less expensive to have 2 or more systems, than one dual or quad socket system, and just replace the computers one at a time. |

I figured since the 32nm chips just started coming out, should be able to do a drop in replacement. I've been a dually nut since I got my first one years ago. Was considering one chip to get rolling then add the other when I raise the cash. 1 grand for a 2.66 xeon 6 core is expensive. Same price as the 980X. Prefer the xeon as these workhorse chips are made to run 24/7 without problems. Not very overclockable though. Hopefully within the next month or so, the full spread of intel 6 core chips will be out and the prices start to drop a little.

You also have to stop and think how long you'll keep a system.
----------------------------------------I haved two Harpertown machines, a SM X7DAL-E and a SM X7DWA-N Both still good productive machines although built in 2006 and 2007. Stable to the point that I have to write reminders to clean fans,etc as they never go down unless we lose power or I turn up the OC in winter or down a bit in the summer. Socket 1366 is over a year old now and how long it will continue is anyone's guess but it's excellent and hope it lasts a while. If you plan on upgrading every other year then single socket is best, once every three and dual becomes an interesting choice. Downtime also has to be looked at and realistically the singles history has more downtime than the duals so it's not only bang for the buck but getting that bang every day of the machines lifespan. |

I've been looking for ways to overclock my harpertowns but haven't been able to find the info. Would appreciate if you can show me the way as to what board would be best. Currently running a ASUS DSBV-DX mobo. Had 2ghz xeons in it before adding the harpertowns so its a slower board. Wouldn't mind experimenting OCing this as if I screw up, not allot lost. Currently running ubuntu but not sure if I need to be running windows to do anything. If I could OC this with liquid cooling, would make my day. Will consider your suggestion on single processor system but the thought of 24 wu's crunching on one system gives me a woody.

I've been lurking here ever since I saw what MovieMan was up to. I still have to go look at the pictures just about every day.
---------------------------------------- I wish I had space for the gigantic case that MB requires.For anyone considering an i7 980X, I would highly recommend it. I finally got mine up and running (thanks to the Microcenter $999 deal). I got all of the parts last weekend, but just now got everything put together. This thing SCREAMS. It's overclocked to 4.145GHz and I haven't even really started tweaking it. It's currently blazing through 12 WCG CPU processes + 1 MilkyWay GPU process (in case I figure out how to time travel and because it's the only ATI GPU project that seems even vaguely useful) @ edit: bummer, corrected temps  CoreTemp apparently doesn't read this MB correctly. I switched to RealTemp and the temps are in the low-60s. [Edit 2 times, last edit by pirogue at Mar 28, 2010 12:21:47 AM] |

@Hypernova:
Now for a single socket X58 machine complete and brand new with high quality top components, 300 GB Velociraptor HD, 6GB fast RAM, W7 64bit and a 100$ video card Unless you're using the machine for things other than crunching, you don't need a fast HDD or a video card that costs even $100. A slow drive will lose a bit of time at system startup, and a little when starting new tasks, but it's not significant for a 24/7 machine. My best cruncher (Q9650) runs a 10 year-old 8.4GB Seagate HDD, literally from my attic, and an old 8MB SiS 6326 PCI video card. You need more than 8.4GB for an HT hex-core, but you don't need an expensive fast drive. Unless you insist on form over function.You can run without a video card at all if you have another machine with a display on your network - I use Windows Remote Desktop to access another Q9650. If you do use a video card, try to get one that comes in a fanless model, because that means that the GPU uses less power. Older cards generally use less power. Graohics Card Power Requirements It could do with an update (hint, MM), but sierra_bound's Crunching tips thread still has some useful ideas, too. |
