(HELP) i7 860 - never OCed a CPU before

post #1 of 15
Thread Starter 
Hello, I am new here as the title says, never OCed a CPU before, since this Chip seems to have a great potential i would like to OC it a bit.
Can somebody with experience with this Chip give me some tips?

Btw all the PC is stock, just tuned the GPU a bit

i7 860 (2.80GHz) Cooling is still Stock
4GB RAM
ATI Radeon HD 4600 (GPU-815MHz MEM-870MHz)


PS: Sometimes I let this PC handle some torrent things overnight... soo maybe i shouldn't OC too far, right?

Thanks in advance =D

That's not really the problem you've got, the i7's on the stock cooler do already get hot. I would recommend going and getting some aftermarket cooling.

The CM212 Hyper+ is a great little heatsink and is by far the best budget cooler. I'd seriously say get that first and then start to OC.

The stock heatsink is good for stock, but not much else.

Hi,
First of all, welcome to OCN

Second, although I haven't overclocked that particular chip before I can tell you that, unfortunately, you'll have to stick to a fairly light OC on that board as its power circuitry isn't designed to handle your chip with an OC.

Now that that's said, the best way to understand the basics is to read a guide and personally I think Miahallen's guides are well written and cover everything you'll need to know.

Edit: Also, as compuman said, you could do with getting a 212+ whether or not you're overclocking as it'll keep your chip nice and cool and prevent any heat-related wear and tear.

Out of the ones on that site, I'd get the Corsair A50, it should handle your CPU up to at least 3.8GHz which is plenty.
Here's a chart with the A50 cooling an i7 965 at 3.8GHz.
It's not the same processor but if it can cool that, it can cool an i7 860.

Edit: Actually, try overclocking a little (to 3 or 3.2) and tell me if it's increased your framerate by about the same amount as you increased your clock speed by.
Your 4670 might be the limiting factor in your PC's gaming performance rather than the 860.

Could you also tell me what resolution you're playing on?
If you're on a lower resolution the card might be okay.

Wow 3.8GHz would be very good compared to the 2.8GHz i have now =D
You mean the Corsair CAFA50?
Titan Fenrir Evo Heatpipe and Thermaltake Frio OCK seems pretty strong coolers too, hmmm

Mind to advice me after I get one of them? =D

Well, with any of those three you should get to the limits of what your current motherboard can do.

Out of the three I think the Frio OCK is the best but I didn't recommend it earlier because it costs a lot more than the other two coolers.

The A50 and Fenrir are pretty evenly matched so either one is a good choice, the Frio OCK is also a good choice if you don't mind spending that much money on it but I doubt it will allow you to overclock any higher without a better motherboard and good RAM so if I were you I would probably just go with one of the other ones as they should be good enough to do the job.

Edit: And if you have any questions about overclocking after you buy one of them I'll do my best to answer them or ask someone who can.

The guide mentioned above is huge help for understanding the basics of the i7 lynnfield OC; it is highly recommended. With that being said, as also mentioned, you motherboard's OC potential may be a limiting factor and reaching a stable 3.8Ghz may not be possible (and 3.8 definitely requires a very good aftermarket cooler). Be aware that to mount a high performance aftermarket cooler requires access to the back side of our mobo, which means that you'll probably have to remove your mobo from your case to install it. These sort of coolers are really tall and you'll need a decently wide case, over 7.5" wide, for the cooler to fit. The CoolerMaster Hyper 212 plus is a really good choice IMO for it'll give you all the performance you'll need and it's relatively inexpensive. For now you can overclock some with the stock cooler with stock voltages, say around 3.1Ghz using a clock of 140 (the guide will be helpful to get you going on this). Enjoy!

Having had 2 different I7 860's being completely different Overclockers.

Your first priority is getting a new cooler yes, Stock won't beable to handle an OC.

you should beable to hit 3600-3800mhz.

My first i7 860 was pretty amazing OC'r and did 3800 Stable on 1.22 Vc, and this one is Stable 3600mhz at 1.21 (running decent bit cooler now on my new heatsink)

Ok friends thank you for your help, i will give news in some days =)
Acidbath, the case size tip makes me wonder a bit if I really have space, seems like I'll need to do some measurements

Btw how do I check if my PSU can handle the new fan and the OC?
