Build with used parts and a 2700k

[salatji]

Hey. I enjoyed building my Main PC. Also i want to learn more about building, tuning and tweaking.

 

When i told my plans of building a PC for overclocking to a friend, He mentioned that He has a 2700k He would give me for cheap.

 

Is this Chip good to overclock and to build around in general? What is the motherboard i should try to get for overclocking? Or would it be a better choice to get a different old CPU/mobo combo to practice stuff like this?

 

I don't need a insane battlestation, i just want a 2nd PC to do office Work, some minor HTML/Java programming (if my further studies lead to this), movies and a few older games Like Diablo 3.

 

 

TechYesCity (of i got His Name right) Made a Video 2 weeks ago about adding a 750ti to a prebuilt system, so this would have been the gpu i would be aiming for.

 

So plans so far for the build are: used 2700k, used mobo (need tips here), 8 or 16 GB of memory, a gtx 750ti and probably a 128GB SSD for boot speed. Let meine hear about the quality of my plans and if there would be a better way to approach things.

 

Thanks for tips!

It can overclock to just short of 5GHz. This depends on luck though, bad examples can only reach 4.5GHz with a voltage suitable for water cooling.

 

Z68 or Z77 mobos are your best choice. Dont get attracted by Z77's PCIe 3.0 support though, 2nd gen doesn't allow that.

 

Whether you should use the 2700k though depends on the price of a motherboard. For what you do even Core 2 Quads or AMD's Phenom 2 x6 can do the job more than well. These are all overclockable btw, but with FSB (front side bus) rather than clock multiplier. A bit different, but this is actually more complex than tweaking the multiplier so they make good practice machines. You need a P43/P45 mobo for C2Qs and Phenom 2 x6 needs a well-designed AM3 mobo.

 

Exceptions are black editions of Phenom 2 x6 Black editions. Their multiplier is unlocked as well so you can overclock just like current mainstream platform (though slightly pushing fsb is possible to get a few extra MHz, just like tweaking BCLK in modern systems fyi)

 

Do note that these chips are sold at the time when DDR3 is a new thing so some mobo support DDR2 while others use DDR3. Make sure you pair the right mobo with the right RAM.

The i7 2700k should overclock well up to and possibly beyond the 4.0ghz mark.

If you can get it cheaper than usual then it's a great buy.

I wouldn't have a clue what mobo to go for but have fun researching things from 2011, 

"Has 2 USB 3.0 ports!" do be careful with old mobos sometimes they don't have Sata 6gb/s as that will shit all over the SSD performance.

Here is a list of chipsets for sandy bridge and there features. https://en.wikipedia.org/wiki/LGA_1155

Have fun

You'll need a socket 1155 motherboard that supports overclocking. Like Jurrunio said, Z68 and Z77 motherboards can do that. P67 motherboards work well for overclocking, too.

 

A 2700k is just a higher-binned 2600k, and should easily reach 4.4 ghz, and has the potential to reach the 5 ghz range. That said, people have reported not noticing significant or worthwhile performance gains above 4.8 ghz, with diminishing returns really kicking in around 4.6 ghz. With a good air cooler, those CPUs should be able to handle up to around 1.42v safely, though most people aim to keep the voltage below 1.4v.

 

Some Sandy Bridge CPUs are made in Malaysia, and others are made in Costa Rica. The ones made in Costa Rica overclock better, needs less voltage to handle higher overclocks. The ones made in Malaysia require more voltage to handle an overclock, and so can't be overclocked as high as easily, and produce more heat at any given OC. You can tell where a CPU was made by looking on the heatspreader.

 

 

 

I have my Malaysia 2600k CPU overclocked to 4.6 ghz, using an air cooler and a voltage offset, which allows for conserving of electricity compared to a static manual voltage overclock. The max voltage my overclock reaches is 1.416v, while it idles close to 1.00v. When you overclock, do not leave the voltage setting on Auto, as that will result in way too much voltage being delivered to the CPU, potentially damaging the CPU depending on how much the core frequency has been overclocked.

What is the definition of "Well designed" in case of the phenom? Because this was initial idea cuz i had a old HP with a athlon X2 where i Just wanted to replace the CPU, sadly the mobo there was only suited for athlons or worse...

Since this will be my testing-stuff-PC, i probably will even use watercooling at one point because IMO it is better to get a leak due to Lack of skills in a old PC rather than a New one

Hey, if its really gives it to you for cheap its a great buy, those still go for around 100$. For 60 hz gaming an overclocked 2700k is almost always just as good as an 8700k and it is modern enough to give you usb 3.0 and sata 3. For what you want to use it itll probably last you many years. If you would want

a cheap renderbox an x58 mobo  +  a cheap 6 core xeon to overclock would also have been nice, but for your application the higher single core performance and better connectivity are superior.

I don't know it yet how much He wants for it or of He also has a used mobo. Will ask him in monday, so i will know more then. He Just mentioned it that it's dusting in his room and i could have it if i would want it. I dont want to spend too much, but if he gives me a good deal, hell i will take it!

Well-designed refers to their power delivery system. If that's complicated to understand then higher end ones should do, such as these
