Getting ready to buy a 4770K, do I need to worry about stepping?

post #1 of 18
Thread Starter 
INFO: I have already bought the CPU, but now there is a new dilemma. Skip to this post to see the situation and offer up any advice if you've got it...

6 years ago I bought myself a Q9550 and didn't pay any attention to stepping because at the time I didn't know what it was or how it affected the performance potential of the processor. I ended up with the C1 stepping, which I only came to find out later was possibly the worst stepping for overclocking you could get in that particular processor. Fast forward to today and I'm getting ready to go out and buy a new i7-4770K that's on sale at a local store for $279, and I want to be sure I'm going to get a processor that's conducive to the 4.5GHz overclock I want to attempt. So the simple question is do I need to worry about steppings with this processor, and if so, where can I find that information because I haven't seen anything like the "C1" identifier attached to the Q9550.

Thanks.

From what I have seen, almost all have been able to hit with absolute ease with any decent aftermarket cooler. Personally, sense Sandy bridge came around, I haven't looked at steppings one bit and got my k to 4.9GHz stable day to day clock. It woudn't do anything higher stable at all, but that seems to be the wall for the lower end from what I have personally experienced. Others may say different, but I'd just say go for it.

hmmm, absolute ease eh. Don't think you own a Haswell..

Anyhow, there are no stepping updates AFAIK, we're all still using C0. If/when I see a newer, I'll be using my Intel plan to change over and hope I get a newer revision.

Ok, so basically, as long as the box says i7-4770K Haswell 3.5GHz, I should be fine? I appreciate the input, I just wanted to be sure I wasn't rushing out to buy a bargain stepping of the 4770K, only to find out that I've painted myself into a corner when it comes to going for that 4.5GHz clock.

Why is the 4.5Ghz overclock so important to you? I mean your coming from a Q9550 a 4770k is leaps and bounds better, what if you cannot get the OC you want..will you be devastated?

Not devastated, but disappointed. One of the primary uses of my computer is FSX, a massive resource hog that has shown time and again to give relatively large performance increases with each tick of the meter above 4GHz. In addition to that, I tend to be a heavy multitasker while at the computer, often running FSX, at least 2 EVE clients, 8-10 chrome tabs, and streaming video or audio, so with all of that going on, every last bit of power that I can squeeze out of my new processor is going to provide me with more overhead to play with. I do understand that even at stock settings, the 4770K is going to be a massive improvement over my Q9550, and if all I'm able to get out of it is 4.1GHz - 4.3GHz, I imagine it will be just that much better, but the goal will still be 4.5GHz.

Completely understand your mindset here.
You could always look around the interwebs for a 4770K that has been tested. That is probably the safest way to assure yourself the speed instead of just picking up a $275 silicon loto ticket and crossing your fingers. I guess it also depends on how much voltage you feel comfortable giving it. I've seen a bunch of forum posts from people who couldn't hit 4.3 without using +1.30v and others who were breezing 4.8 with 1.30v. The range is quite wide with Haswell from what I've seen.

Hi treblesum i run FSX too thats why i went from my AMD vishera @4.58 gig to the haswell, which i cant do better than 4.2, but believe me even at stock it runs all over the 6300. Still even at that FSX is a bit limited but what an improvemnt just get a decent heatsink and turn off Hyper Threading.

Regards

Ok, first of all, why not wait for 8 real core CPUs ?

Second, if you're using FSX, your goal should be 4.7 not 4.5 Ghz. FSX is core-eater sim which means you're gonna need every CPU processing power you have, 4.5 wont be enough when you're flying with NGX + REX + heavy Aerosoft airports with real-time weather coverage.

If you can wait, wait a bit more for next-gen chips.

Also there's Prepar3D V2.0 which can be considered as Flight Simulator 11. It's still BETAish simulation but much better than what we have in FSX. The thing with P3D V2 is, it's GPU dependent unlike FSX, so you might want to upgrade your GPU unit instead of CPU.

It'll support Sli configuration, means better perf. Also 64bit native version is considered by Lockheed Martin, means no more OOM.

From what I've read, the Haswell-E 8 core CPUs are going to hit the market at around $1000, which is way over my budget, and the Broadwell 14nm chips are basically going to be more efficient Haswell designs, meaning that an 8 core CPU that is going to fit my price range isn't going to be on the market for at least another year, if not more, and my system is just too old to support that much more time, at least in my opinion.

Now, I am planning within the next 12 months to replace my mishmash of different screens with 3 identical ones and then after that upgrade to a top-end video card (probably the GTX 880 by that time), but that is going to have to come after this system core upgrade.

EDIT: I should also point out that my current rig can run the combination you've described at about 14-18 fps, not great, but smooth enough to cope with. I'm hoping that a much newer and more powerful processor with a much faster memory is going to improve on that significantly.
