    Upgrading to 24GB of RAM....

    24 GBs sounds a bit extreme to me, but then again I probably have different usage patterns than the OP. Might I suggest the OP run some perf counters to see if RAM is really bottlenecking his system? As other's have indicated, some RAM may be caching data which will be evicted if another...

    SSD AHCI quick question

    IIRC, you should be able to switch on Win 7 and newer versions. XP (and possible Vista) did not ship with AHCI drivers, which would result in an unbootable OS if you switched the controller to AHCI without first installing the ACHI drivers. Win 7/8 *should* automatically detect the new...

    Best 4x Space Game?

    You might consider giving AI War a look if you haven't. From my brief playing (few hours on tutorials), it's basically sort of a mix mash of Sins of a Solar Empire and Gal Civ II, minus factions/diplomacy, but with a more novel AI opponent. Also on sale on steam for ~2.75ish.

    Looking to reduce compile time.

    You don't mention what OS your tool chain is on? If you're on Windows, double check that your build directories are excluded from your anti-virus scanning - when I was working on firmware at Intel, adding our build directory to the AV exclusion list gained us about 20-30% performance boost...

    Out of the game for years, little help on a new build - re: 3 dimms vs 4...

    Too true. $2000 should set you up with a very nice setup - I'm a bit jealous. But, then again, I don't think I have anything that I play or do professionally that would benefit all that much from such an awesome computer.

    Good time to buy a SSD (Intel 520 180gb $229)

    Heh, just saw your other thread. While it does suck that it died, 1 failure does not make an entire product line "unreliable". If you have examples of a lot of others with similar experiences, then you might have a good case against a particular drives reliability.

    Sigh Intel 320 160 gig dies 2x in a week (8MB bug)

    Just to be clear - is this a single drive that's failed on you 3 times, or is it several drives that have failed on you. If you've seen more than 1 failure, definitely RMA it. Bad parts do occassionally make it past QA, and it isn't worth your time to keep fighting a likely defective part...

    Good time to buy a SSD (Intel 520 180gb $229)

    No drives are 100% reliable. It sucks that Anonemous's drive died, but that's mostly annecdotal evidence (bad drives do occasionally ship). I've heard good things about Intel, Samsung, and Crucial's m4 lines. Unfortunately, without a look at actual return rates, it's more of a "feeling"...

    Out of the game for years, little help on a new build - re: 3 dimms vs 4...

    Hate to say it (because it looks like it may be too late), but dual channel operations looks to only add ~5% performance at most. In most benchmarks, it adds even less, with performance benefits in most games less than 1%. You'd probably be looking at a larger boost from file caching with more...

    Any advantages of creating a separate partition for data?

    Partitions primarily exist to help organize date. Your use case of creating an OS paritition for mirroring onto an SSD at a later date is a great use for paritions. Partitions can also make it easier to do formats on a disk and not use all your data. One note about mirroring - do some...

    Why isn't ECC memory used more?

    That really sucks - I'm sorry to hear about your problems. By any chance, are you sure that the issue is the memory and not something else? A bad firmware/os update? A faulty drive? A bad motherboard or a bad NIC? I hope you're still under the manufacturers warranty so you can get it fixed...

    Why isn't ECC memory used more?

    Personal attack much? People asking questions, like you, help others develop an understanding. Before this thread, I dismissed ECC as an unnecessary expense for most people. After looking at the numbers I'm a bit more concerned for my own data reliability. But I still don't believe I have...

    Why isn't ECC memory used more?

    There is no legal obligation what so ever - CPUs, RAM, etc all come with warranties which expressly limit liability due to damages from data loss. No company in their right mind would ever sell a part that warrantied data loss unless they added the cost of data loss into the price of the...

    Which NAS? Needs to handle 3TB drives, 4 or more

    Only a RIP off if you like tinkering with OS's and networking configurations, have a lot a free time, or have constrained funding. Let's not forget whole system warranties either - if something breaks you can ship the whole thing back to the manufacturer rather than trying to track down which...

    Why isn't ECC memory used more?

    ECC is good. Errors are bad. Intel is inflating prices through segmentation. These are all facts that can be discussed rationally. Cost delta, acceptable error rates and others are also facts that can be discussed, but there are no hard numbers you provide. Everything else is zealotry -...

    15K HDD implementation through RAID

    Performance wise, SSDs will always be your fastest option. You don't mention what the network connection between your server & PCs? GigE? Fiber, 10Gig? And what number of NICs does the server have? If you only have a single GigE connection to your server, once you start using a single SSD...

    RAID 0 SSD, any real improvements in the real world?

    I think you answered your own question. "Real world" covers a large amount of applications and uses. For some, RAID 0 SSDs can save them time and resources for the work they use their system for (professional image processing, professional audio work, data base use, etc). For most consumer...

    Why isn't ECC memory used more?

    Interesting disk failure rate research: http://research.cs.wisc.edu/adsl/Publications/corruption-fast08.pdf Seems to indicate ~8% check sum hard disk failure rate on SATA disks (see nearline failure rates) - roughly in line with ~8% DIMM failure rate. I couldn't find the pupblication date...

    Tynopik, your passion has inspired me to settle this issue with science!

    Why isn't ECC memory used more?

    I think I'll have to agree to disagree with you, tynopik. I agree with most of your points (memory errors are bad, ECC either detects for fixes most of these errors, etc), however I still believe you're over emphasize both the chance of corruption (you've provided no hard numbers) and that the...

    Why isn't ECC memory used more?

    Quite true - depending on the error correction (including Chipkill) errors in the ECC codes themselves aren't fatal. However, not all ECC memories implement Chipkill, a metric I believe the google DRAM study addresses - http://www.cs.toronto.edu/~bianca/papers/sigmetrics09.pdf From memory...

    Boot performance issues with SSD

    If boots was the only time the SSD RAID didn't perform, it's probably due to the RAID BIOS. As a computer boots in BIOS, it may execute code contained on a devices option ROM telling the BIOS how to read/write to a device. Think of the option ROMs as a crappy form of an OS driver - most of...

    Why isn't ECC memory used more?

    Just for fun - what happens if your single bit error is in your ECC code? ECC codes are stored in memory like the rest of the data and aren't immune to corruption. If you have a single bit error in your ECC code, it'll likely show up as an uncorrectable error to the OS.

    Why isn't ECC memory used more?

    How is ECC "not optional" like hyperthreading, or even more cores on a CUDA chip? Your statement hyperbolizes the issue - you make it seem like without ECC computers will be crashing every day, and documents will "rot" into an unusable state quickly. Companies actually do perform quality...

    Best way to connect a laptop HD to another laptop or PC?

    The GoFlex looks like a nice solution, but depending on the hard drive, it may not always provide sufficient power to the drive. USB spec states .5 Amps @ 5 V = 2.5 W. A quick search for "2.5 inch hard drive power draw" shows some drives have a 2.5 W or greater seek power draw. Now, most...

To borrow from a slightly, but always popular analogy - would people pay more...

    Why isn't ECC memory used more?

    I think "lots more" is a bit of an over statement. An often quoted google study puts DIMM error rates at 8% of DIMMS have >= 1 error/year. Another slice is 25,000 to 70,000 errors per billion device hours per Mbit. The google study is here: http://research.google.com/pubs/pub35162.html...

    Why isn't ECC memory used more?

    The thing that bothers me about the whole "screwing the consumer" line of logic is that most of the time it comes across as a "I want more crap for free," and less of a "business are consciously trying to screw consumers." Chip manufacturers have employed mechanisms of "soft SKUing" chips...

    How much RAM is too much? 32gb? 64gb?

    AFAIK, there is no "error correction" on non-ECC memory controllers. Of course, I haven't looked at the electrical & physical signaling spec of DDR3 memory interface, so perhaps there's some error correct somewhere (though, if it's at the signaling level, you essentially get it "for free" from...

    need good reliable ram

    You're wasting your money if you go over 8GB. Heck, for your intended use, you're only going to see marginal returns on your investment going over 4GB. For a computer for MMOs/LoL I'd prioritize components as follows: i5-2500K (or equivalent Ivy bridge) > 8 GB > Graphic Card > SSD. Meaning...

    Premade NAS Expensive Why?

    I'm in the same boat of Jeffspears - I like the synology, but the cost is a lot higher than a more capably self-built server. I think the question that needs to be asked is: how much do you value your time & reliability of a device. I always used to build my own systems, especially when I...

    My Intel 320 SSD (120 GB) review (IDE vs AHCI added)

    Doh! I knew I forgot something. As groberts points out, AHCI can dramatically improve performance in benchmarks for some SSDs (this can also include heavy multi-tasking and server workloads). However, under typical "consumer" load, the queue depths usually hover around 2-4, which has a...

    4GB vs 8GB

    ^^ Agree with the whole "ram disk" thing. Tons of research and development has gone into file system development, and part of that includes file "caching" and prefetching. Unless you have a ton of evidence that your file system configuration is bottlenecking your performance (say, perhaps with...

    Actually, contrary to what everyone is saying, AHCI won't deliver much extra performance.

    4GB vs 8GB

    The question the OP needs to ask is if the ~$40 is best spent on extra RAM? There is no downside from upgrading to 8GB - it'll never make your computer slower, and even if it doesn't speed up your current set of applications it may speed up a different application in the future. For your...
