sout posted:I've always had a twin CPU cooler on my PC, I think this one I've seen some good results of using a pressure optimized fan pushing + an AIR FLOW optimized fan pulling, gives better results vs pressure optimized fan pushing + pressure optimized fan pulling, but in both cases more fans = better. BIG HEADLINE posted:I remember thinking I was loving something up when I was trying to lock my 2500K into my motherboard during my last build. I kept thinking "there's no loving way I'm supposed to be putting this much pressure on the locking bar," because I was trying to be extremely careful to not bend any pins beneath. But evidently I did it right because the chip's been purring like a kitten for over three years at 4.4Ghz. Did it also make that horrible grinding crunching noise like you're crunching some grains of sands in a bench vice? I felt like a bomb technician on his first day at work using help from loving Google results.

Talking about pressure optimized airflows, is there a reason why CPU fans don't have stators? Well, there's that single fan model from Noctua that has some, but that's about it.

I'm no expert but maybe the tolerances would have to be a lot tighter to make use of that. I feel like if you used staters the back pressure caused would just limit airflow too much.

I've been doing some fine tuning of an overclock with c-state/speedstep stuff and was surprised to notice it so low. It's been stable and everything but I want to make sure I'm looking at the correct label and not the wrong voltage. This is right, Haswell C6/C7 reduces core voltage below .2V. This is why most PSUs weren't compatible with Haswell at launch. http://www.techspot.com/news/52423-most-power-supplies-wont-support-haswells-c6-c7-low-power-states.html If you want to read some about C-states, in C6 its within spec for the VCore to go all the way to 0V: http://www.hardwaresecrets.com/everything-you-need-to-know-about-the-cpu-c-states-power-saving-modes/

You know how you normally have to *force* new Intel chipset drivers to install on your system, especially if you're using an older board like my Z68? These didn't do that: http://www.guru3d.com/files-details/intel-chipset-software-installation-10-1-1-8-whql-download.html New USB Host Controller drivers, PCI Express Controller Driver, PCI Express Root Port drivers, SMBus controller drivers, Z68 LPC Interface Controller driver... ...I don't know what half of this poo poo is, but so far, so good. They were a bit of a 'scary' install, though - since they upgrade your USB host controller, you'll have a period where everything's locked up, and you will/might get a black screen before they're done installing. EDIT: Though when you do examine the PCI Express Controller and Root Port drivers, they still point to pci.sys. BIG HEADLINE fucked around with this message at 21:52 on Jul 14, 2015 |

Ah Intel drivers  If you ever need to install their USB 3.0 driver on Win7, right click the exe first and uncheck the "this file came from a remote computer" thing. Otherwise you'll get a security warning every time you login/reboot.

That's because Windows already knows to load PCI.sys for that device. All the Intel inf file is really doing is providing a human readable device name. Many of the devices in the inf file don't load any drivers at all.

They generally recycle wafers if they're bad, whether in house or to somewhere else that purifies things back out. In either case they break them into itty bits so no one can reverse engineer stuff. My friend's dad had him for a take your child to work day at IBM and he spent an hour just smashing old wafers. Like $50,000 a piece

Having not paid attention to new CPUs for a while, but looking to build something once the 6th gen comes out, what happens to previous gen prices when new CPUs come out? Seems like I'd save on the motherboard and RAM prices on the older stuff as well if the two are close enough in processing power.

They don't fall much because everyone has figured out when to stop producing old stuff so supply dries up at retail right when they're ready to ship their next generation. It's usually best to buy right when a generation shifts. Usually price drops only happen when there's a surprise from competition and they're forced to respond. Unless you're looking at used, there will be tons of people upgrading and selling their old stuff for 50-100 off retail.

Seems like I'd save on the motherboard and RAM prices on the older stuff as well if the two are close enough in processing power. Intel never drops prices directly on old stuff. New stuff will come out, be the same price as the old stuff (Or within 10$ or so), and that's that. Eventually the old stuff will go up in price as it's not made any longer.

Micro Center really drives any price drop on new Intel chips. They've got enough of them spread out around the country that despite being 'smallish,' they can still bully Newegg and even Amazon around a bit on computer components.

When trying to remove the 4670T from my B85 board, I let it tap the LGA pins and they bended. I then tried to unbend them and then pulled them off instead. Good thing it only cost $50!

Crap like that is why I dislike LGA's to this day. At least if you bent a pin on a P4 or AMD chip you could just use a mechanical pencil with the lead removed to carefully bend it back in place. Worked most every time.

That was the reason given but AMD has been able to do pretty well with 'regular' sockets for quite a long time now so I'm not sure how necessary it really was to do it.

LGA 775 started with Prescott and Smithfield, which had quite possibly the worst power-efficiency of any Intel CPU in history. I think people are kidding themselves if they think the primary reason was anything but to shift the issue of damaged pin damage to MBs.

It was just a joke. Even if pins on the socket side allow a lower input voltage it's not like any particular chip design is required to use it, and changing which side the pins are on obviously isn't going to do anything to power use all by itself. I think at this point it's even sorta moot since the voltage regulators moved on to the chip itself with.. Ivy Bridge? I don't remember when intel started using their fully integrated voltage regulators.
