Hi,

I am searching for a mainboard for an for an Intel 2600K with Onboard Graphics and USB 3.0 ports.  Overclocking should be possible. Is there anyone, who can give me an advice?

Thanks,

Bernd
Parent - - By SchachProfi (****) [de] Date 2011-01-27 21:48
Bernd, problem is that currently only P67-chipset supports serious overclocking, but hasn't support for the onboard Graphic.
H67 and the others on the other side doesn't support serious overclocking. Z68 to come will support both.
I would go with a P67-Board an buy a ~30€ graphic card... Alex

Hi Alex,

what about consumption of energy? Is this system using much more energy?

Bernd
Parent - By SchachProfi (****) [de] Date 2011-01-27 22:20
No worry in 2D-mode Bernd, absolutely no worry... Overclocking will way more push energy up than a cheap-old graphic card could ever do in 2D... but still you can wait for the Z68 to have one suiting your both needs.

2600 K has usb 3.0?
Parent - By Banned for Life (Gold) Date 2011-01-29 20:52
USB 2.0 is incorporated into the chipset (H67 or P67), not the CPU. Most Sandy Bridge boards have additional circuitry to support two or more USB 3.0 ports.

It would be desirable to consult with who has a system of cooling of Koolance liquid nitrogen CPU-LN2-V2 Evaporator (CPU)
. As often you should fill cooling system - nitrogen by operation of the computer of 12-16 hours a day at 100 % to loading overclocked processor. Yours faithfully Nikolay.

For Phil Harris (and other experts), I'm looking to buy (or have built for me) a new PC. I would appreciate a recommendation of a system (either from mainline vendor, e.g., we own 2 Dells) or to be built by a local shop (I have one water-cooled overclocked Intel quad-core system used for chess based on Phil's recommendations.)
This new system would be for my wife and would primarily be used for Photoshop editing with these general specifications: Windows 7; 6-core; at least 12 GB of fast RAM; and 2 HDs, of which one would be SSD. The system would not be water cooled.

If I did any O/C, it would be a small and safe O/C (10-25%) vs. the successful 50% O/C on my current chess system (Antec Swiftech case, Asus P6T Deluxe V2 LGA 1366 MB, Intel Core i7-930 2.8 Ghz, Kingston HyperX 12 GB DDR3 1600 RAM, Intel X25-M Mainstream SSD 160 GB SATA II)
I would prefer a system from a mainstream vendor for the warranty, but Dell's reviews have been negative on delivery, price, and warranty issues. I would look at Dell's Alienware or Asusl.
I'm open to having the system built for me. Thanks in advance to all the experts.

Phil is in the UK. I'm in the U.S.
Has Phil been on the board recently?
Parent - - By Werewolf (*****) [gb] Date 2011-08-02 07:57
Haven't seen him. If you were in the UK 'Overclockers' would be worth a look, they do mild and more ambitious overclocks, although I'm not sure how good their aftersales service is - I've heard mixed things about the company.

Dell is always a safe bet!
Parent - By cma6 (****) Date 2011-08-02 23:36
Werewolf, thanks for the ideas. Hopefully, someone here will have an idea about what components I should be looking at.

Thanks to The Hug and werewolf. I assumed I had to get an Intel 6-core, but you are saying that I may be able to get an  AMD 8-core at an incredbily low price ($325). I don't know how that price can be right.
I just got an email from Phil Harris recommending the following system on eBay.
http://cgi.ebay.com/NEW-INTEL-CORE-I7-990X-EXTREME-3-46GHZ-24GB-DDR3-1TB-/200638217539?pt=Desktop_PCs&hash=item2eb6f83d43
The Intel processor is about $1000 on New Egg.
How can AMD offer a much better processor for 1/3 the price?
Also, I would appreciate the appraisal of both of you of the above eBay system, aside from your advice to wait for the new AMD 8-core.
Parent - - By Werewolf (*****) [gb] Date 2011-08-06 17:04
At the moment I'd wait just another month to see what Bulldozer will look like. Depends on how much you want to spend.

If you need something ASAP just go with a decent Sandy Bridge CPU & M/B that allows overclocking and read up on a guide about how to do it. But personally I'd wait for AMD to show their hand.
Parent - - By cma6 (****) Date 2011-08-10 23:24
Werewolf:
Thanks for the advice. I'll wait a month and then see what you and The Hug think of Bulldozer as the basis for my new system. But the rumored price for the chip at $325 seems incredibly cheap for an 8-core, doesn't it?

> But the rumored price for the chip at $325 seems incredibly cheap for an 8-core, doesn't it?


Well, yes, but bear in mind AMD's 8 core is not a true 8 core by Intel's standards - some of the resources are shared in Bulldozer making it perform (if the leaked benchmarks are true) like a 5 core intel system.

But yes - AMD are better value for money than Intel, typically. Intel are usually faster though. (At the moment Intel's 6 core processor is much more expensive and much faster than AMD's Phenom II 6 core)

I am considering upgrade to i7 980X
Does anyone have experience with overclocking this CPU?
Is watercooling necessary when OCing as is claimed in some fora?
Any advice on good coolers?
Last but not least the recently released i7 980 has pretty comparable speed benchmarks at half the price. Is this true?
Thanks all!

Why not wait for  Sandy Bridge E? Same 6 cores/12 threads with the modern architecture of Sandy Bridge.
Parent - - By cma6 (****) Date 2011-09-10 00:00
Hi Tano-urayoan.
I am waiting to build a new system based on Werewolf's comment here: "At the moment I'd wait just another month (9/17/11) to see what Bulldozer will look like. Depends on how much you want to spend."
  What do you see as the pros and cons of Bulldozer vs. Sandy Bridge E (cost, speed, and how soon)?
                       Thanks, CMA
Parent - - By tano-urayoan (****) [pr] Date 2011-09-10 02:21
Hello cma6:
The problem is bulldozer seems to be a metaphysical mystery right now. It was supposed to be launched next week or at least somewhere in September but it has been delayed yet again to October. So it is anyway guess how it will do.

I read that you want a pc for doing photoshoping and similar tasks. Maybe the 2600k is enough for your needs. But if you want more cores (6/12 in this case vs 4/8 in the 2600) then wait for Sandy-Bridge E. It is the sandy bridge architecture but with 6/12 same as Nehalems like 990x or 980.
Parent - - By cma6 (****) Date 2011-09-10 20:23 Edited 2011-09-10 20:32
Hi Tano-Urayoan:
  Thanks for the very useful post. The Intel 2600K looks just fine for my wife's new Photoshop system. (I will come back here in 4/12 for a recommendation for a new O/C chess system for me.)

I see that the 2600K has has 4 cores/8 threads. What do the 8 threads mean in practice?
Is it a good idea to use all 8 threads by default for chess or for Photoshop editing? 

I am sold on your chip recommendation. What other elements of the system would you, Werewolf and the other experts recommend to go with this system that I will have locally built:
case; MB; RAM; video card; HD; CD/DVD, PS, etc?
I want very large RAM (16-20 GB, assuming Windows 7/Photoshop can use the RAM).
Also need 2 HDs: primary HD will be SSD.
I will go with the stock speed of 3.4 GHz, so I assume that no cooling is then necessary.
                            Thanks, CMA

Hello again Cma6

> What do the 8 threads mean in practice?


That you could do more things with your computer at the same time, or finish your workloads earlier.

> Is it a good idea to use all 8 threads by default for chess


No

> Photoshop editing


In this theme I am ignorant I suppose it will help.

> MB


Here you have various choices the main boards will be P67 or Z68. From there you could find any of the top vendors Asus, Gygabite, Msi or even Asrock. The difference between is Z68 is a more redifined model using more features of the Sandy Bridge arthitecture. It could use the integrated video from the CPU, SSD caching, Virtu. But as you wanted for photoshop a graphic card is needed, maybe 2 in SLI or Crossfire configuration for more powerful graphics.

> RAM


This is correlated to the motherboard you choose. Gskill, Corsair any of the major brands should be ok.

> SSD


Here you need to ask how much capacity you want, did you want it for just OS and more important programs, or you want all your programs to run in it?

> HD


This will be for backup or you will install other programs in it? maybe a 2tb disk from any of the major vendor, Western Digital, Samsung, Seagate. Or maybe 2 1tb in raid configuration.

These chips are so easily overclockable that just a minor change in bios/uefi will give 4+ Ghz.

   So you are saying that with the Intel 2600K I have a choice of the type of MB to use: Z68 or P67 compatible?

That is correct any motherboard within the family P67 or z68 is compatible with the 2600.

I have recently built a new PC based upon an ASUS P8 Z68-V PRO motherboard, an Intel i5-2500k processor, 1600 DDR memory, Windows 7 64 bit.

I overclocked it to 3.9 Ghz with no problems, upgraded the cooling (to a Zalman CPNS10X quiet) and then upped the clock rate some more.   I have had it stable at for long periods at 4.3 Ghz and 4.6 Ghz running chess engines flat out.  The memory is barely overclocked.

I just have one problem at the higher speeds of 4.3 and 4.6 Ghz - if I put it to sleep using the Sleep facility in Windows it will not restart properly.  (In fact to get it to restart at all I have to disconnect the power, reboot, then Windows does restart OK but needs rebooting again to get full clock speed).   Sleep and restart was working fine at 3.9 Ghz.   

Has anyone come across this problem before?   And any ideas on how to solve it?   I have upped the core and PLL voltages a little to no effect, though in truth I have more headroom there I could try.
Parent - - By Regularuser (***) [gb] Date 2011-09-12 18:02
I solved this by changing the power settings so that Hibernate as well as Sleep is available & everything is fine with Hibernate.    It's a bit slower to wake up than Sleep but at least it works OK
Parent - - By Banned for Life (Gold) Date 2011-09-12 18:57
Hibernate and sleep use hardware features (interrupt types) on the CPU that aren't otherwise used, so it's perfectly possible that everything else would work at some overclock, but these features would stop working.
Parent - - By Uly (Gold) [mx] Date 2011-09-12 19:02
It it possible to use the Sleep feature in Windows XP?
Parent - - By Banned for Life (Gold) Date 2011-09-12 19:30
Sleep is called system standby (and sometimes suspend) in XP's Power Options Properties.
Parent - - By Uly (Gold) [mx] Date 2011-09-12 21:34
Oh, it's Standby? So that means I can't go into Standby and unplug the power cord like I can with Hibernate?
Parent - - By Banned for Life (Gold) Date 2011-09-12 21:36
You can, just don't expect to get your data back! :-D Only hibernate puts complete system state on the hard drive...
Parent - - By Uly (Gold) [mx] Date 2011-09-12 21:40
Okay, thanks, I didn't know Sleep=Standby. They could have avoided confusion by... keeping the old name.
Parent - By Banned for Life (Gold) Date 2011-09-13 03:41
Some marketeer probably thought it was clever to have sleep and hibernate (deep-sleep).
Parent - By Regularuser (***) [gb] Date 2011-09-13 07:05

I am giving some thought to a new build myself instead of going any further with an upgrade to an i7 990.

However, Intel is changing the scenery a little too fast for my liking casting yet another socket to contend with for their 6  Core (i7-3960X) which pisses me off. I have absolutely no funds to through into every Intel whim that comes down the pike- now almost yearly. 

I can see them coming up with yet another socket for an 8 core cpu next year.

The other end of the spectrum-

Judging from the reviews from customers re: mobo's   ( asus et al) -  a great many are ending up in RMA.  China, or wherever, these components are being manufactured -don't seem to have the skilled labor to do the job correctly, or decent quality control- it becomes  hit and miss, and I'm talking about premium mobo's. When you put about $350 or more into a mobo, you'd expect a quality return on the product.  When you see 300 reviews half flat out one star and half 5 stars on newegg you know things aren't going well in the industry.

It is turning into a class A joke.

AMD- I don't trust their core quality!
Parent - By Regularuser (***) [gb] Date 2011-11-25 08:16
I stick to lower than the top end in the interests of value for money and not being too tough on the planet, but it has the advantage of avoiding the worst of socket changes.  My only exception over the years was my PIII 933 with an 815 chipset which a fantastic rig for a year years.

I am confident I will be able to stick an Ivy Bridge in next year in place of my i5-2500K.   But I am not confident Intel will make it worth my while - not enough competition from AMD :(

Parent - - By Arrière Pensée (Gold) Date 2011-12-03 05:08
There are plenty of  tutorials on you tube that can give you a sense of what you need to do to learn how.  Your mobo  should have some programs that aid you in overclocking and most importantly monitoring parameters et al.

You should also download and run  Prime95 for at least 3 -to 6  hours or longer  to make sure your setting are stable.
Parent - - By Banned for Life (Gold) Date 2011-12-03 06:45
I never really understood why people who are interested in chess engines would test their overclock with Prime95. It's much more useful to test with your latest analysis project.
Parent - - By Arrière Pensée (Gold) Date 2011-12-03 07:08
I've notice that prime95 picks up an unstable setting if not immediately , within about 45minute to an hour where as running analysis, or chess engines at full load hasn't shown errors as quickly. This has just been my experience. Maybe I'm not utilizing the GUI effectively enough to produce the stress test necessary to adequately test stability?
Parent - By Banned for Life (Gold) Date 2011-12-03 15:46
There have been times where I've had an overclock that was very stable for chess, but couldn't perform some other tasks. I guess this would have concerned me more if my chess machines were doing other things...
