We didn't receive these processors with any retail packaging as they arrived straight from the Intel factory.
The Xeon E5 is one of the most complex processors that Intel have designed to date. The E5 2687W has 8 physical cores, each of which have hyperthreading support to offer a total of 16 threads. Therefore in a dual CPU configuration there are 16 physical cores with a total of 32 threads.
The E5 2687w has a massive 20MB Level 3 cache onboard, even more than the Core i7 3960K Extreme Edition. Officially it has support for memory rated to 1,600mhz in a Quad Channel configuration. There are 40 PCIe plus 4 V2 lanes and two high speed QPI links.
The Xeon E7 range of processors are designed for use in 4 socket and higher servers, so the E5 has to cover a wider gamut of deployment situations.
The Xeon E5 2600 is the first CPU to truly integrate the IOH functionality for 40 lanes of PCIe Gen3.
The E5 2687W slots into the top of the E5 range – clocked at 3.1ghz and with a TDP rating of 150W. Confusingly the ‘higher named' E5-2690 is clocked at a slower 2.9ghz but with the same turbo frequency of 3.8ghz. It consumes less power (135W) and is therefore better suited for 24/7 server use. The ‘W' moniker of the 2687W indicates the suitability for a Workstation environment.
Both processors should be very closely matched, but the 2687W has a higher standard clock speed, so will have a slight edge depending on the given situation.
The Quad channel IMC in the Xeon E5 also supports DDR3 LRDIMM to allow for densities up to 768GB – 24 x 32GB modules. Intel Turbo Boost 2.0 is incorporated which helps improve performance while maintaining a dynamic, efficient power curve.
And there was me thinking my 3570k at 5ghz was awesome 🙂
shame on me !
Go on, give it away, please?
Would be nice to see some opteron reviews too. Cover the amd side of things.
thats a very nice system, but it does show that software is way behind the hardware. exactly the same sorry situation in the world of gaming.
We need a new Crysis and new application support for many cores.
The coders are lazy, although it makes little sense to develop a lot of time to multiple core support when most people have dual/quad core.
Most games ive looked at only use one core however, its a poor showing.
You should have known that on Xeons overclocking is BLOCKED – and this includes not only CPU clocks, but memory as well… 1600 is the highest you’re allowed to go – until Ivy-E next year which is expected to provide 1866. Annoying, isn’t it?
Well I stand (or sit) corrected on that one. I thought they could load the XMP profiles, but clearly not. thanks.
im currently have a similar setup, but on a cosmos 2, and both h80is dont fit on top they touch the top board passive coolers, too bulky ,so i need an advice how to setup this coolers, i saw on your nuild the h80s running wiht only 1 fan? how is the performance of those in that way?
The run great. bear in mind the 2687W’s aren’t producing too much heat when they are running at default clock speeds and voltages. Temperatures were well under 70c under extended load. As long as you have decent air flow, one fan is not a concern. Its only if you were to overclock and push voltages the two fans would be very useful. With Xeon’s being locked, it isn’t a concern.
If you are mounting the coolers at the rear, or top, set the single fan in exhaust configuration.
so ill try to put it on top with the fans outside pushing air inside, that will be ok?
Will the single fan not fit inside the case? I would set them up as exhaust unless you are mounting the radiators at the front of the case.
the problem is that the asus mobo has 2 passive coolers on top of the board and the radiator with the fan inside dont fit couse of them, so, thats why im planning to put them as intake, and only 1 fan each 🙁
I wouldn’t mount them in an intake position at the top of the case, even if they are outside the case. Hot air naturally flows upwards. you would really cause a problem for the airflow of the case if you set them as intake flowing up to down.
Should all still be ok, as long as you have good cool air intake from the front/side of the case.
looks like the cosmos 2 is well ventilated, 2 front, 1 back, 3 to the psu… im going to try the fron cage solution
I’m running this board with Predator 2133MHz using a VCCSA of 1.2V got it stable 11-12-11-30-2T 1.6V so consider that one negative may be solved.
