The current line of Xeons are based on the same architecture as the i7. The difference is usually that the Xeons are the cream of the crop. They run cooler and at lower voltages and are spec'd for 24/7 continuous usage. Otherwise, performance is usually identical. Xeons are able to be used in multi-socket motherboards, where i7s are not (which is why the Mac ...

From looking up some stats on Sandy Bridge CPU temperatures it seems your 60 degrees Celcius is indeed quite high. Should you be worried? Well not if it stays at 60 degrees Celcius, so I recommend you do a stress test like Super Pi or Prime95 and keep an eye out what this does to the temperature. Looking at some overclocking temperatures from ...

Another difference between Xeon and i7 is that the Xeon supports ECC memory, the i7 does not. Also, some Xeons are designed to work in multi-CPU systems, whereas absolutely no i7 models do. As such, if you want a multi-CPU system, you must use nothing less than a Xeon.

Definitely does. You want to talk about Nehalem first, the quad-core should be discussed after that. Start from the Wikipedia notes on Nehalem ArsTechnica articles -- What you need to know about Intel's Nehalem CPU Intel's Nehalem simply sizzles -- Don't go by the title, but do look at the points With i7, soon you will say ta-ta to the North Bridge even on ...

I have an i7 2600K and P8Z68-V LE. It should be similar in your computer. The hardware virtualization setting is located in Advanced mode->Advanced tab->CPU Configuration-> Intel Virtualization Technology According to this page, your i7 2600 will support VT-x and VT-d. My "K" (unlocked version) only supports VT-X (so Intel can still sell Xeons) so yours may ...

You cannot put a notebook CPU in a desktop motherboard. If you want a notebook CPU in your desktop, you basically need to put notebook components in a desk case. There are some companies that do that, but it costs a lot. What you can probably do is buy a low-end desktop CPU that will have a low TDP. These, however, are likely to have relatively poor ...

Nope - DDR2 and DDR3 are electrically different and not cross compatible. Pic: DDR3 on the top. DDR2 below. Edit: Nice diagram in this answer too: Can you tell DDR and DDR2 apart visually?

File compression and CD ripping are probably being limited by your laptops IO subsystem. The usual benefit of a faster CPU is that you can do something else while it is ripping/compressing etc. If you usually wait for a single task to complete before starting the next task then you probably wasted your money buying more CPU than you actually need - at ...

The i7 supports 8GB per memory controller. There are 3 controllers, 24GB max. Check out i7 datasheet. This is a chip design decision - a function of the interface to the chip.

At one point, at wholesale, memory makers were changing designs by the week (well, month, but it felt very quick!), so if you bought in bulk from a supplier, even buying smallish quantities such as 10 sticks, you could get three or four different designs - it was a nightmare as dual channel (back then) didn't always work as some designs were to different ...

You're mixing two things up... x58 is a chipset used on the motherboards for i7 processors, x86 is the family of Intel processors that i7 is still a part of. To kind-of answer your question, i7 is still part of the natural progression of Intel processors, latest and greatest... and if you want to use it you will likely be using an x58-based motherboard to ...

Depending on the application, some applications are only coded to utilize 1 or 2 cores. In order for you to see a performance gain with a quad core processor, the application must be designed to support the extra cores. For example: http://www.legionhardware.com/articles_pages/starcraft_ii_wings_of_liberty_beta_performance,7.html

My guess would be that it is throttling down due to heat issues. Find an app that can report CPU temperature and see if the temperature rise correlates to a drop in CPU throughput.

cpu load in bios can range from 80-100% depending on the mobo, which surprised me (I thought the cpu would be sitting close to idle in Bios This is easily explainable. If you boot into DOS, you will also see the temperature rise. Why? Because back in the days that DOS and BIOSes were first written, overheating was not really a problem, so there was no ...

This will vary from board to board, but there should be an explicit BIOS option for "Intel SpeedStep" or "EIST" that you can disable. EDIT: Also, I believe you have it backwards. SpeedStep is responsible for downthrottling, not upthrottling; you'll run at the base clockspeed if you turn it off. Turbo Boost is what upthrottles (but I believe SpeedStep does ...

They do, but they're referred to as "Workstations". Workstations are essentially a server, but with expansion abilities more like a desktop. You get all the benefits of a server (symmetric multiprocessing, stability, management, hot-swap, etc.) plus the things you wouldn't normally have in a server, like video card(s). Check out Intel's Workstation ...

You might have to set the boot device, but generally no, you don't have to set anything up. I'd still open it up and LOOK at the settings, just to see what's available for changing later.

Sounds wierd, the i7 should be shipped with heat sinks having thermal compound pre-applied to the base. Are you sure there isn't any on the bottom of the heat sink? Or a thermal pad installed?

Quoting here: All Sandy Bridge designs also incorporate a dual-channel DDR3 controller, suggesting that the triple-channel system used by the LGA 1366 platform is being sidelined. “We’ve found a very high percentage of clients will only tolerate two memory channels,” explained Opher Kahn, senior principal engineer for Sandy Bridge. “OEMs wanting to ...

You should be able to do that using the performance monitoring tool that comes with windows 7, which is a 'snap-in of your management console 3.0. I have windows 7 professional, i am not sure if its integrated in Home Edition. just hit your 'windows'-button and enter perfmon in the textfield (search programs/files). once that is open you can unfold ...

You'll want to look for a board that is identified as having "B3 Stepping" for the chip-set. Sometimes listed as a "Rev. B3" and sometimes there will be an "Intel Revised" logo, depends on the motherboard manufacturer for the most part, but they all tried pretty hard to ensure it was obvious that it had it. CPU-Z can help you identify it on a running ...

There are certainly lots of changes and improvements, it's not just marketing speak, there are genuine improvements. I haven't tried one personally, but there are two features that I would consider looking at for potential performance gains: 1) Re-implemented Hyper-threading. Each of the four cores can process up to two threads simultaneously (with some ...

Based on your description, and this is just a guess, this could your hard disk starting to spin.

Thermal paste is definitely needed, they're just being cheap if they don't put any on. Get some Artic Silver, from the tests I've seen it's the best. Running a CPU that high end without it will result in a dead CPU very fast.

i7 is a brand name for a group of processors based on the Nehalem processor architecture by Intel. The five "specifications" you're referring to are code names for different versions of the i7. Each codename indicates are particular set of features, which may or may not be shared across versions. They differ in the following areas: The "process size", ...

AnandTech have a good comparison of the performance of these CPUs. The performance is very similar, but overall the i7 860 is faster. The i7 860 is a newer CPU, but there are some benefits for opting for a Bloomfield CPU (such as the i7 920): 1) High-end multi-GPU performance (or other uses of high bandwidth PCIe) 2) Stock Voltage Overclocking 3) ...

The Intel i series tends to do this. They have a certain thermal limit built in and basically manage the system such that: if you are running on all cores, it manages speed among them and tries to run the system as fast as it can without overheating. If you aren't running all cores, it will shut down the cores that aren't used and try to overclock the ...

Many computers have BIOS options to disable cores. You can also disable hyper threading which is also disabling cores, though I doubt that would improve cooling much. A final thing that could be done is in Windows itself. Go to the Advanced Boot Options (msconfig > boot tab > Advanced options) and specify the number of cores you want to use. I ...

One core, with or without hyper-threading, can simulate any number of virtual cores, simply by timeslicing. However, this produces all kinds of problems because the operating systems expect that code running at the same time will actually interleave. Overprovisioning can lead to performance drops so great the system can appear frozen with operations ...
