Hi fellas,

I would like to OC 2600K,

what can I get out of the GIGABYTE GA-Z68XP-UD3 or Asus P8Z68-V

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I would like to go 4.4GHz max if possible. Do I need a water block or the stack Intel will do just fine or I should get better one?

What is a safe OC here on a good cooling system?

Are the mobos fine to do the OC? Or do you have a better recommendation?

Does it matter what RAM I'll get?

Thanx

Both of those motherboards will be perfectly fine for a 4.4Ghz overclock, Out of the two you've listed I'd opt for the Gigabyte board as it has some passive cooling for the CPU's power delivery.

I wouldn't recommend overclocking with the stock cooler, but you don't need watercooling for 4.4Ghz either. get a decent air cooler like the Noctua NHD14 or Silver arrow.

Most people recommend to stay below 1.4V for a safe 24/7 overclock, I'm using 1.51V but only because I have high end watercooling and don't care about my chip.

The RAM you selected is fine for a sandy bridge build, although excessive for most people's needs, 8GB will be more than enough if your a gamer.

omgitzfatal's answer is right on ... Here's my setup

Intel i5 2500k~4.5Ghz @1.36 vmax | gigabyte p67a-ud4-b3 Mobo | 2x4gb gskill 1600mhz cas 8 | evga GTX275ftw GPU (soon to be upgraded) | noctua nh-c14 cooler | 620w corsair modular PSU

I need RAM for Ramdisc and CS5 likes it : )
I am upgrading from C2D E6750 to i7 2600K, I have a Gigabyte mobo 965P DS3(never problem running 24/7), so I like Gigabyte.

I am not a gamer, but I will CS5 and video edit a lot.

I will hook up at least 3-4 SATA2 and 1-2 SATA3. I have HD5550 GPU

1 or 2 Vertex2 SSD, I have them. I have a 500W 5 years old PSU

What about these 2, I think it will have enough power, even OC'd, right?

How is that Noctua NH-C14 CPU cooler vs stack?

Doesn't matter, the Gigabyte board supports RAM upto and including 2133Mhz

HDD's don't use much power at all, SSD's use even less , No need for a 600W PSU

I was thinking that would be under 500W, but didn't want to run out of juice when OC.

Just so I understand, that does not have anything to do with OC? Or at least at this speed?

1600 CAS 9 is the recommended RAM in general for sandy bridge processors. Any of them will work with the board, but the Gigabyte doesn't support 2000 so it'll step down to 1866.

In general higher speed is more important than lower cas latency, but only up to a point. If there is a big difference in the cas latency then the slower speed might be faster to retrieve the requested memory. However, with that said the real life performance difference is very minimal so I wouldn't spend a lot of money getting "better" memory than the equivalent amount of cheap 1600 CAS 9 ram.

I've got a pretty bad 2600K, it requires alot of voltage for a small overclock compared to other 2600K's and even my chip will do 4.4Ghz with only a slight bump is voltage, your 4.4Ghz overclock won't be using much more than stock power usage.

If you plan on upgrading your GPU at any point then grab a 500W+ PSU, with your HD5550 there's no need.

I got these Sapphire HD5550 1GB DDR2 for$9.99 @ Microcentrum I asked them if there is anything wrong with them, they said no, the price is right, so I went for 3 more and week later it was $74.99 and they didn't wanted them back either. Used them for christmas : )

Yes, I will upgrade to 3 monitors so I have to think about that too. Good point.

Thanx

temps stay low

Right, and stack Intel would not take the heat?

When I see something that does well, I bookmark it for later, especially when upgrading my now grandfather PC : )

But the Vertex2 pour new live in it.

With Bigkid's overclock you could get away with the stock intel heatsink as it looks like he/she is using less than stock voltage (voltage = heat).

However thats not to say your 2600K will be as good an overclocker, your chip may require more voltage, and so produce more heat.

Since I have to buy new RAM, will my RAM disc benefit from faster RAM or the difference will be not noticeable in the real life?

I see, I was thinking about the Corsair water cooling, just to keep things quiet. Never had one tough, is there any special maintenance needed, since u have water block already?

with the noctua in the 50's i'm pretty sure a stock cooler would be quite a bit hotter --- my guess well above 70 -those chips can go 90+ but ...well ...cooler is better

You still need a fan on the radiator for the corsair watercooling series, plus you've got the noise of the pump aswell.

If your after silence then get a good high end air cooler (either of the two I mentioned earlier would be fine) and buy some very low RPM fans (800-1200RPM) This will still give you decent cooling but will be pretty much silent.

I wouldn't class the Corsair watercooling series as proper watercooling, but they don't need any maintainence.

I guess I'll stay away from the water, have to get some decent air cooler than.

I know about the radiator, but I always hear how quiet is the water cooling : )

I do alot of 3D modelling and rendering which taxes the CPU heavily, so rendering times has decreased significantly, I've also gained performance in some games that require a fast CPU.

Thats like comparing apples to oranges. Noctura cooler will be probably 10c cooler at full load on stock settings. At 4.4 it should keep it below 70c or close to it. I doubt the stock cooler could keep it below 100c at 4.4.

Thanx for the input. I will not go with the stack anyway.
