  1. I almost bought a pair of 32GB DDR4-2400 kits (well, a single 64GB kit)

    Are you 100% sure? I think if you install memory size that larger than the CPU can handle, the system may not even able to boot. :sneaky: e.g. the i7-990x officially only support up to 24G RAM. If you install 4x16G, the system may not just can't use all the RAM, but may not able to boot. (May...
  2. Why does read speed slow towards the end of a failing drive?

    The error correction cost lots of time.
  3. 1TB SSD for PS4?

    Theoretically it should be better. However, PS4 system is not design to take benefit from SSD, so, the real world speed gain vary a lot. I read a test from a local game magazine, which shows some operation is faster, but some others may be slower than SSHD. However, a SSD for sure can...
  4. SSD Recommendation-

    850 Evo
  5. Install Win10 on M.2 SSD 256 GB or on SSD 2.5" SATA III 1TB

    850 Evo, because the much better 4k read performance.
  6. X58 and memory

    If you want something fast, X5677 is a good choice as well, unless you really can utilise all 6 cores of the X5650. Another cheap choice is the W36xx CPU. X56xx are build for dual processor system, they are more expensive then the W36xx CPU (with exactly the same core count, speed...
  7. Western Digital Blue HDD failing but SMART says otherthing.

    I am not a computer professional. However, I did ask some computer guy. Their general comment about SMART is... HDD fail whatever SMART says; If SMART says your HDD has trouble, you better chance it ASAP. Therefore, SMART is reliable to confirm a HDD failure, but not a good indicator to...
  8. Slow USB 3.0 speeds

    Even though GC will work regardless if TRIM is there or not, but TRIM will make GC work much much better. They are somehow related, not totally independent. GC can only recover the cell that marked no longer occupy with useful data. without TRIM, GC cannot recover the cell that no longer use...
  9. OK to mix RAM as long as they have the same speed, capacity, timings, and voltage?

    In general, mixing different size, speed, timing...DDR 3 RAM is not an issue. The system should able to automatically pick the highest possible speed (the lowest between the sticks), and run on that speed. e.g. Almost all 1600 RAM can run at 1333, 1066 etc. If not, manually set the parameter...
  10. Slow USB 3.0 speeds

    If that slow speed only happen on writing, but not reading. That may be because no TRIM available via USB connection. Without TRIM, GC cannot zero the cell which no longer require to store any data under the file system. Therefore, in the controller's point of view, the SSD is actually "full"...
  11. Looking for HDMI Extender

    Hi all, I will move back to my newly renovate home soon. For the new setup, my Computer will be on the 2nd floor (computer corner), and my 4K TV will be on the 1st floor (living room). So, I would like to get a HDMI + USB extender (via CAT cable) to make me able to play 4K games on the TV...
  12. Which storage device is best for high heat environments?

    I think SSD is a better choice (if cost is not an issue), even both the HDD and SSD rated at the same temperature, the SSD itself will generate less heat, which reduce the chance than the HDD itself heat up the environment and cause the temperature outside the envelope.
  13. SSD PCIe v SATA

    Sounds like the computer take around 30s to initialise the PCIe adaptor + SM951 combo.
  14. Am I wasting $$ on a Samsung 950 Pro SSD?

    For boot disk, OS operation etc, that's a waste. All you need is the high IOPS, but not the high sequential read / write speed (the PCIe SSD's main advantage over the SATA SSD). A 850 Evo is the good choice for that, much much cheaper. Work it as hard as possible until it die (many years later)...
  15. Xeon or i7 4790k?

    Yeah, they never update that page. I guess they just type in all the info at the beginning base on the CPU's "expected behaviour", and keep it forever, no update, no correction.
  16. Xeon or i7 4790k?

    Haha, I didn't realise that I use the wrong word. Terms corrected, thanks for pointing that out, and sorry for my poor English. Anyway, I am not kidding. A spaceship in 1997 proved that it receive 280 bit error per day constantly. And some solar activity will double that figure. However, The...
  17. Xeon or i7 4790k?

    IMO, use XEON because of prefer to use ECC memory. From statistics, there is about 1bit error per GB memory per month (due to cosmic radiation). That means, nowadays, on a 32G memory system, there is about 1bit error per day. If that bit is on the idle memory, then doesn't matter. If that happen...
  18. What CPU do you use for your primary gaming PC?

    W3690, stock 3.46/3.73
  19. memory upgrade for gaming

    If your mobo has another slot, you should consider to buy the 4th RAM stick and put it there. The real world difference of fully utilising the triple channel or not is less than 2%. You can't feel it (apart from the benchmark numbers). My CPU is also in triple channel. The speed difference of...
  20. SSD Sata 2 vs Sata 3 user experience?

    I have a PCIe SATA 3 card and a 840 Evo, which gives me 500MB/s R/W in benchmark. If I run my 840 Evo via the SATA 2 port, then the benchmark shows only 250MB/s. However, I can tell you that I really can't tell the difference in real world normal ops. No matter it's the boot time, application...
  21. 5930x max memory

    In my own experience, the spec in the Intel page may not be the hard limit. According to Intel, my W3690 should max at 24G, and now I am running 32G, and so far the tested hard limit is 56G (3x16 +8). I personal consider the info in Intel page is the "max demonstrated" limit, but not the real...
  22. Do 2 and 3 TB HDDs have any reliability issues?

    For your info. I am now using a 4T WD Red with another 6T WD Red. The 4T was there for more than 1.5yr, and the 6T only few months old. No problem so far.
  23. Anyone on Windows 10 yet (how are drivers/stability)?

    Dual 7950 CF, works very well so far, no crash during game or benchmark.
  24. Add matching size drive to create RAID 1 - Reformat or just pop it in and turn it on?

    I am not a Windows user, but did use RAID 1. The whole idea of RAID 1 is to keep the system alive (not really for backup purpose). So, in case you remove one of the drive (or a drive fail), the system will keep running run on the remaining drive. No crash, no restart.
  25. New Build Share! My GF new PC! X99S SLI Krait Edtion PC

    Don't let your GF know this Graphic card exist :sneaky:
  26. Confusing Radeon HD 7950 Problem (I might be dumb)

    I also have a Sapphire Radeon HD 7950. In my own test (OC + low fan speed), the GPU won't crash until 95C. Anything between 80-90 should not be a problem at all.
  27. Radeon HD 7950 Owner's Thread

    I have a Sapphire ref model. 87C is not a problem at all. In my extreme test (OC + custom lower fan speed + no air conditioning in hot summer), the card won't crash until 95C. In fact, I intentionally let my card run up to 88 (to reduce noise) for few months (when loaded, not 24/7), no problem...
  28. Turning off PC with power switch

    I did that from time to time (because I want to switch off other stuff that right next the the computer's power socket). Never damage anything, but of course, it may cause data corruption, and not a good practice at all.
  29. Your CPU history?

    486DX2 Pentium II Celeron D W3520 W3690
  30. Best program for diagnosing and benchmarking a new SSD ?

    For the 840 Evo, make sure it's firmware revision is EXT0CB6Q before you do anything. If not, upgrade it by yourself, otherwise it may has performance issue few months later.
  31. Fixing discontinued iPads: What's Apple's policy?

    No worry, even my ipad 1 they can still fix it. However, there "fix" is actually mean a replacement. It cost me 9 days in Hong Kong because they need to ship a new iPad from somewhere. They said that's new, but I don't really care. Even though it's a refurbish item, it looks new anyway, and they...
  32. Looking for 2015 Gaming PC advice

    Thanks for the info. I didn't follow MS closely, and good to know that some important may be coming up soon. I definitely can wait, and willing to pay a bit more to achieve my goal (if that really help).
  33. Looking for 2015 Gaming PC advice

    I know, but is it 3D related? My understanding is... 1) UHD 30Hz in 2D = 30 3840x2160 pictures in 1 second 2) UHD 30Hz in 3D = 30 3840x2160 pictures in 1 second, but every picture contain 2 narrower picture (1920x2160) side by side (or other format). Then the TV will stretch each half picture...
  34. Looking for 2015 Gaming PC advice

    Thanks for your comment, DigDog. Yes, I will use controller but not mouse or keyboard. I am totally OK for that to play BF4, Metro, TR, etc. I prefer to sit on my sofa, and play games on my TV. I don't want to spend money on something that I don't need. So not the 3x monitors setup at this...
  35. Looking for 2015 Gaming PC advice

    So, if I want to play anything at 3D, the graphic card will work twice harder. Because it draw everything in UHD, and draw everything twice (for both left and right eye), and then reduce the picture size (e.g.1920x2160), put them together to make a side by side (or other format) picture at...
  36. Looking for 2015 Gaming PC advice

    Thanks for the speedy reply. I am seriously looking for that, after some studying, my conclusion so far it's only possible with a huge case (it seems a proper water cooling system, including water cooled GPU, will required a large case). So, may be wait for a bit longer, and some new hardware...
  37. Looking for 2015 Gaming PC advice

    Hi all, I am looking for some advice to build my real 1st gaming PC. So here is the info. 1. What YOUR PC will be used for - Pure gaming :D. 2. What YOUR budget is - virtually no limit, but of course, as low as possible. I can easily afford anything that cost USD$5000, I think it's not too...
  38. Request for Samsung 840 EVO SSD owners (write amplification calculation).

    My computer is running 24/7, if this info help :D
