Just out of curiosity I checked the latest v5 Xeon processors as a possible upgrade for us people that got the cheap i7's aka v3 Xeons.

Sadly Intel has decided to kill of any support for consumer mainboards Sad

Can this be fixed with some mainboard firmware hack?

That would be like 5% "upgrade" anyway? Cannot be seen anywhere. Only real upgrade is to move to more cores.

Sorry, I didn't mean to actually upgrade, but if intel is doing this with the v5, I simply guess that upcoming Xeons won't work on consumer hardware at all Sad

not unexpected, they "lost" a lot of money with supporting consumer sockets last time. and most of the xeon series prior were tied to special sockets too. and they will most likely go again for more cores on the cpus but with lower clock speed cause its more effective in many applications

How do you mean they lost money? Didn't they sell enough specialized server mobos for the xeons or what?

Don't know if you already saw it, but at least Gigabyte will sell compatible Desktop-Mainboards in Germany sometimes in the middle of december:

Though personally i would just get a v3. At least for me Skylake doesn't offer anything important, that would justify the higher price.

ah nice, just read the original article and not the updates.buuuuuuuut: 100 euros is too much, the boards must go for about 70 euros to make it reasonable to buy a xeon instead of the i7 for home use

Hmm.. I did a bios upgrade to my mainboard and now the option to unlock my xeon has disappeared Neutral I didn't use that feature but it sucks that they removed it! (I think the unlock would force all cores to run at max speed when required)

Were there any known problems with this unlock or did intel bully them to remove this feature? Sad

yep that would have been the boost on all cores stuff. and yes intel forced the oems to change the microcode in the bios to disable that (thats the reason is still stick to the bios version which is two years old). boost of 3,8ghz only on one core is meh.

just get yourself a mod bios from http://www.jzelectronic.de

you may need to register and maybe it costs you 2 euros or so to buy that modded bios. but that guy is reliable, doing it since years and tests every board/bios with the old microcode injected to reenable enhanced turbo mode. or just give him a call, if some extra settings in the bios are needed to reach full boost on all cores (i.e. extra multiplicator settings he will tell you)

Can't I just download and flash an old version of my bios? I "accidentally" updated my bios by playing around in the settings and it said auto update and I got curious how my bios can update itself without a proper image available.. Turns out my bios can go online and download that shit all by itself Very Happy Pretty impressive (keep in mind I come from the old era Laughing)

ofc modern uefis have build in network drivers to download new images without the hassle to need a fat32 stick or whatever where you put the image on

and yes maybe you can do a downgrade, some boards dont allow them though (and dont go to low if your cpu maybe wasnt supported at inital release of the board)

I use a BIOS/UFEI-editor to update/add/change modules (like SATA/RAID, Network, Graphics etc...) Been a while though. And you'd have to find the right modules for your particular chipset/board (comparing ID's to make sure you get the right firmware modules for your hardware).

for a new job PC:

5820k or 6800k ?

6800k has more performance
but 5820k has more instructions like mmx, sse4.2, etc. do those matter for work pc?

Kaby Lake is out in the wild already (*insert cnc generals china will grow larger sound here*)

everything went as expected

http://en.expreview.com/?p=2416&page=4

~10% performance gain due to optimization and little clockspeed boost. only 3-4% in gaming (that was to be expected)

interesting to see will be the power consumption (which should be lower than sky lake) and how it performs with oc

Voltage seems a bit high for such a recent CPU model (I could be wrong of course.) but I don't think the temps are anything to worry about, especially if you have the CPU in a active state and running at that speed constantly. Smile
(I'm on a 3930k myself which has a larger fab or how it's called at 4.1 Ghz though while the specs will state it as a 3.2 Ghz CPU the boost or turbo is 3.8 which since I have the whole speedstep thing off it's at that constantly so it's "merely" a 300mhz overclock without voltage adjustments.)

On top of that thing is a Noctua DH15-2011 (or was it DH14-2011?) so it's kept in check via sheer force. Razz
(That thing is effective, but also really heavy.)

EDIT: Ah it's a hexa core too, thought the i7 5900 series was octa (8.) but that seems to only be for some "special" (E or Extreme.) models of said CPU series.
(And for the 6000 and 7000 series it's 4 core again with some upcoming 6 core models.)


Silicon lottery and all that but yeah it seems 4.2 and above could require 1.3v indeed with some models possibly at 1.25 depending on what exactly you trying to reach. (4 - 4.5 Ghz)
https://hardforum.com/threads/i7-5930k-safe-voltage-with-safe-temp.1834657/

Far as temperature goes some with water cooling peak at around 70c but that's with "torture" test in Prime so it fully stresses the CPU, one person using fan/air cooling had 85c which to me seems really hot for a CPU but apparently it was stable.

(And around 60 to 70 Celsius for regular gaming came up a couple of times.)

The right time is when you either need it because 1. you need more performance in your games/apps 2. yours is kaputt 3. you urge for novelty and a new build.

Nothing in the next two years will really be revolutionary. Kabylake is bascically Skylak and Kabylake refresh will be just more of the same. Yawn...
