    1366 x58 Xeon Enthusiast overclocks club

    I searched a good bit and haven't really found any serious discussion regarding running these much over 1.4V for daily usage. I've found a handful of anecdotes of people running 32nm Westmeres at 1.45-1.55V accidentally or intentionally for extended periods with no claims of failure or greatly...

    NVIDIA Unveils The Titan X At GDC 2015

    How do water-cooled TitanX overclocks compare to water-cooled 980 overclocks? Is anyone getting 1550/8000+ with these? ~1400 seems to be the highest people are reporting this early, but I haven't found more than a handful of results and none under water. I think the real world performance...

    ASUS ProArt PA328Q 4K Monitor

    "Following ASUS' $799 28-inch 4K monitor from earlier this year"? following!? really? that's pretty bold language considering the 28" is still riding on a 6 month paper launch so far or maybe they're implying you shouldn't get your hopes up for this one actually shipping either :rolleyes:

    Overclocking results in no sound

    Some of the hexcore xeons will run computationally stable at a higher BCLK than the buses (PLLs?) can operate stably at, the bus ECC may play some part in masking the issue. They will start to have unstable tsc due to missed cycles and tscs are synced between cores only once at boot, while most...

    How did this happen?

    I have a loop with 2 480 radiators and a single Koolance PMP-500. My (Tygon) return hose to the reservoir is a short angled tube run from the last CPU block and it nearly always partially collapses like in the picture. After the hose partially collapses my measured water temperature is...

    Growing Linux RAID and reducing nr. of disks - nervous, need input

    It will probably work but it would seem like there's a much higher than usual probability that you're going to run into some bug in a rarely tested corner case doing that much shrinking, growing and swapping. If you do not parity scrub it's likely that any parity RAID which has been used for...

    E5-4650 Turbo Mode

    /proc/cpuinfo shows the rated speed of i7 processors regardless of their set BCLK*multiplier, turbo, or speedstep. I believe this was clarified by Linus on a mailing list somewhere (I don't have the link handy and may be misattributing) to be the intended behavior a few years ago in spite of...

    For environmental concern, what's the average wattage on 2 x Xeon (quad. core)?

    I couldn't say offhand what the actual power usage is "with numbers", but a properly configured dual socket i7-Xeon system (LGA-1366 or LGA-2011) shouldn't use terribly much power at low load. With speedstep/turboboost/c-states/etc all enabled the idle cores clock down to as low as 12x and...

    stress tester for retro AGP card

    That video card is one of the latest AGP cards produced and is a lot newer than the core of your dual socket A system. It claims to have OpenGL 3.3 and DirectX 10 support. You shouldn't really have to look very hard to find supported benchmarks. (3dmark vantage or earlier should work) Radeon...

    Nvidia K1 demistified :)

    nVidia has been backing off their "stellar" support of proprietary PC drivers for several years, at least from the Linux perspective. We haven't had overclocking on Linux for soon to be 4 GPU generations and essentially every non-trivial feature is officially supported for Linux drivers only on...

    SR-2 Optimization Thread

    Vtt 1.4, uncore multiplier 16x, and memory settings (in my case DDR-800 multiplier, DDR-1600 MCH strap auto defaults, 1.65V) seemed the most relevant to high BCLK stability One of the CPUs has 3x 8GB DIMMs and I am pretty sure they are responsible for the uncore / memory setting sensitivity, at...

    SR-2 Optimization Thread

    Is 1.456V set VCore (1.43-ish measured) with Vdroop off too high for 24/7 on x5650s? Is there a overvoltage breakdown or extremely accelerated degradation due to VCore at some point for the 32nm chips, or is the main concern thermals? Has anyone run with high or very high VCore on these chips...

    Trying to tune 16 core 62xx ES

    220V supply should improve power conversion efficiency in practically all cases by like 1-3%, but you would want to run 220 into the PSU. Nearly all recent PSUs of quality are 110/220 auto-sensing and even cheaper or older PSUs will have a 110/220 switch, but you will probably want to confirm...

    SAS backplanes

    I don't think there are any single expanders with enough ports to offer 4 paths to 48 drives, but you may be able to use multiple expanders. As in, use 2 28-port expanders to connect to drives, and a 3rd 28-port expander to aggregate the drive-connected expanders while connecting to 4 host...

    Linux RAID (mdadm) - RAID partition + OS partition on the same disk?

    The main motivation in RAID-1 of the swap isn't performance, but it certainly won't hurt compared to a single swap partition. It's mostly to prevent the system from crashing after paging out to a disk which later decides it is tired of your crap :p Incidentally, multiple swap devices will be...

    Linux RAID (mdadm) - RAID partition + OS partition on the same disk?

    I generally use RAID-1 boot/root (with GRUB failover), RAID-1 swap, RAID-5/RAID-0 data partitions. I've set up dozens of headless co-located servers like this and never had an issue with the use of multiple partitions for md. If you set up RAID-1 boot/root and GRUB failover it will usually...

    Which 775 mobo works with IBM m1015?

    I have an M1015 (and nVidia GTX-260 GPU, Mellanox MHEA28-XTC Infiniband HCA) stuffed into an EVGA 780i SLI FTW. The M1015 worked fine with the RAID bios and when flashed to IT mode as well. This board has electrical x16/x16/x16/x1 with the NF200, if you can find one on eBay it's a pretty good...

    Help with first overclock (Q6600/780i)?

    The 780i can be tricky. The talk about FSB/memory holes is no joke, particularly with unlinked FSB/memory. If you can't POST around 3.4-3.6 but have stable 3.0-3.4, before you dial back or push much voltage you may want to play with the target memory and FSB to get it to select different...

    To all the Q6600 out there.

    I recently upgraded my desktop from an eBay G0 Q6600 in an eBay eVGA 780i SLI FTW with 4x2GB to a forums-purchased D0 i7-920 in a B-stock eVGA x58 SLI with 3x4GB. The Q6600 setup got a GTX-480 a few months ago that carried over to the new setup. The Q6600 was at 3.0 for a couple years and...

    M1015 for external enclosure?

    So just in case anyone was curious about the CK23601, internal/external bracket, Chenbro's claims about the "Out" port, etc.: I tested with only the expander's "Out" (i.e. cascade-only, according to Chenbro) port connected to the controller. This configuration definitely works. I have both...

    (really) Flat 90-degree 6-pin PCI-E power adapter/extension board for 3U?

    Using a card with the PCI-E power connections on the back is definitely an option, but I already have the GTX-260 with power connectors on the side. The "right angle extension" PCI-E cables look like standard plugs with the wires bent over to the side. I'm pretty sure I actually need a lower...

    (really) Flat 90-degree 6-pin PCI-E power adapter/extension board for 3U?

    I'm trying to stuff a GTX-260 into a 3U rackmount, and the cover won't go on with the two 6-pin PCI-E power cables connected. The wires and most of the plugs extend above the plane of the cover. There's ~1cm of clearance between the board and where the lid should be. I've looked at some 3U...

    Best Storage Chassis for Multipath W/O SAS Expander

    The SAS/SATA 5-in-3 modules use SATA-style connectors because they support 5 drives, while there are only 4 channels on a SFF-8087 connector. You would use a pair of SFF-8087 to SATA fanout cables to attach it to the controller, with 3 channels from one fan-out left over for internal drives or...

    Best Storage Chassis for Multipath W/O SAS Expander

    Incidentally, I saw a 5-in-3 SAS/SATA backplane module that broke out the dual ports into a pair of SATA connectors for each slot the other day. Huge footprint for a 2.5" SSD array so I won't bother finding the link again unless you actually want it, but it is confirmation that things like this...

    So what do you use SSD drives for?

    I moved my root partition to a new 60GB SSD the other day, and a few choice applications (root on SSD already includes a huge number of applications, in this case I'm referring to some larger applications from /opt and other locations). I run Gentoo, so having root on SSD is pretty wicked...

    Best Storage Chassis for Multipath W/O SAS Expander

    There are dual-port solid state and magnetic SAS disks that support multipath with no expander. You could use 6x external SFF-8088/SFF-8088 multilane cables, 6x 4-port SFF-8088/SFF8087 brackets, and 10x dual-port SSDs (but you might as well go with 12x as you'll have 24 channels to the array)...

    M1015 for external enclosure?

    So the M1015 came in today, without a bracket :mad:, but with a 46M0864 feature key installed. :confused: I'll be using OS softraid, so I guess I'll have to sell the feature key to recoup the ludicrous cost of the bracket from SCSI4ME.

    M1015 for external enclosure?

    I've been doing some reading and I don't think there's any reason to suspect the bracket will be an issue as long as attention is paid to the cabling. The number of connectors in the Controller-Bracket-Expander signal path is the same as in the Controller-Backplane-Drive signal path, so there...

    M1015 for external enclosure?

    Here's a dumb question. I use Supermicro CSE-M35T-1B 5-in-3 SATA backplane modules. In the SATA Port Multiplier setup, I have 5 wires running from each port multiplier to the backplane's activity LED pins. I don't see any activity LED pins on the CK-23601 SAS expander. How would I get the...

    M1015 for external enclosure?

    There is evidence to suggest that the CK23601 supports dual-linking, in spite of Chenbro support claims to the contrary. http://hardforum.com/showpost.php?p=1037763507&postcount=60 provides basic evidence of dual-linking functionality between M1015 (SAS2008) and CK23601 (LSISAS2x36)...

    M1015 for external enclosure?

    I haven't been able to find any OEM equivalents to the 9200-8e. I was hoping to take advantage of dual linking, although it's not strictly necessary. It seems that for around $180 the M1015 can be made to provide 2 external ports (with a bracket) that support dual linking. The M5025 seems...

    M1015 for external enclosure?

    Does anyone use a 8087-to-8088 bracket adapter (e.g. http://www.pc-pitstop.com/sas_cables_adapters/AD8788-2.asp) with their M1015 and an external enclosure? Are there any signal strength issues resulting in excessively high CRC errors? I'm currently using a multilane SATA bracket (4x e-SATA to...
