Hello,
I have been thinking of overclocking my i5 750 a bit.

I am running stock fans in the Antec Nine Hundred case, the stock with the i5 750 CPU, and a 650watt PSU.

I believe the stock runs at 2.67, I want to overclock to 3.0 or 3.25 for future scalability (video card; as I read that a CPU can bottleneck a GPU).


Will OCing my CPU help with less potential bottlenecks in my GPU (currently a Zotac GTX 560 ti) or upgrading to a GTX 670/680?


I do not want to invest in a new system yet, but I want to play games that come out before the new year.


How will I go about doing this?
 


Defaults that came with the case, CPU and my PSU...Maybe I should not even bother with the OCing until I get better fans it seems..

These temps (last picture) are during the Prime95 test...otherwise it seems calm
 
There's a reason that one of the first things I wrote in my guide is:

"Prerequisites

The second thing you need, and this is very important, is good cooling. The case itself needs to have a decent amount of air flow. Typically most "aftermarket" cases will be sufficient, but if you upgraded the motherboard using one of the smaller HP/Dell/etc towers, you may need to make some changes. I've seen many that only have 1 exhaust fan, on the bottom. Ideally you would have at least 1 intake and 1 exhaust. On top of good case cooling, you also will need good CPU cooling. Typically the stock cooler that comes with a CPU is not going to cut it for overclocking. You might get a very small performance bump out of it, but it will quickly run out of thermal headroom. Ideally you need an aftermarket tower cooler, even a cheaper one like the Hyper 212 Plus."

You can overclock a little bit on stock voltage with your CPU cooler, but that's it. I'd back it off until you pick up an aftermarket cooler, those temps are dangerously high.

As many people said... read guides and do some research. Temps are one of the single most talked about items concerning OCing.

Also, yes I know your case is the 900 not the 900 II, but it still has 2 intake fans on the front and 2 exhaust fans. The case should have fine air flow, but you need a cpu cooler.
 
Hi Guys,
I understand this, and I made this clear that I was using STOCK before I dug into this, but nobody seemed to recognize this.

Anyways, I will likely invest in new fans in the next little bit then try it again...
 


While it wasn't explicitely pointed out by us, most of the responses you got were "do research first", and any decent guide (many of which were linked) do in fact talk about the importance of cooling. Given the advice, it was assumed you would read that.

And you don't want "new fans". You want a CPU heat sink. The Hyper 212 Plus/Evo are probably the best bang for your buck coolers right now if you don't want to spend a lot.
 


I dont mean sit there and read 8 hours a day for 4 weeks straight. I would go mad reading forum posts for 8 hours straight by itself. Spending 10-20+ hours of your time to research something you really want to do is barely anything. I thought I found that "good guide" then I found a "better guide" then I ran into issues and needed to track down a "different guide". Every guide is similiar but not the same. The biggest hassle is finding mobo specific guides.




You know you can disable the windows splash screen to knock off 2-3 seconds from your boot time.



Read lots. Hyper 212 is great, cheap, efficient. You can get creative if you would like with some lights and add a 2nd fan for a push/pull system that will knock off 3-4 more degress if you want. Just make sure it will fit your case. I want to say it will fit just about any mid tower, but most of us only have 1 to compare from.
 
I dont recommend over clocking anything that is not water cooled , And i recommended over clocking everything that is . Listin to the guys when they say research ..I have yet to see a lockjed cpu the i5-2310 i have says locked at 3.2 but it runs 3.8ghz at 41c (however it is serious water cooled 3 pumps ) but you have to consider so many things like front bus speed , ram speed , bios ect ect i could go on and on so if you have not spent the time or money for your self your only wasting peoples time dont ask them ask "GOOGLE" submitted with respect . Its just like this you cant expect some one to do your home work when you have done none of your own , Or first thing is you would not think of overclocking with out first replacing cooling system from stock .....summery upgrade your ram and a ssd for 80 bucks , then min 60 bucks on cooling (myself $600 and at least 75 hrs on cooling system) then come back ....please dont respond used my grandma account on fb for fast login to reply
 


Are you out of your mind? I have a Hyper 212+, that I spent $20, and my 2500K is rockin a stable 4.6 GHz overclock. Stop trolling posts that are over a year old and giving out bad advise. You should do your homework first before suggesting anything.
 
Were did that guy come up with the idea that the i5 750 would be hard to overclock because it is locked? Anyway Overclocking will not be impossible, but go easy on her she is a little older now. 3.2ghz is a good speed, Especially if you are already running 1600 ddr3. But A i5 750 at stock clock will not bottleneck any new cards trust me. My brothers runs a GTX 770 fine. Not to mention i5 750s have run ATI 5970s And those cards are hoss cats too. And mine runs a GTX 650Ti
