Yea I grabbed the I5 would have loved to have gotten the I7 but a little out of my price range.

Is there consensus regarding safe 24/7 voltages for Broadwell chips? I picked up my 5675C yesterday and have it overclocked to 4,4 @ 1.312 V. Should i aim for 4.3 @ 1.268 V or can i use it with these settings?

I don't know if this information will help, but after testing the broadwell 5775C OC during Computex 2015, I think it's not really that prepared for overclocking (maybe that's why they didn't call it K). In the short testing session, I only got 4.2Ghz cinebench-able. Did everything I can but it won't boot past 4.2Ghz. In 4.3Ghz it sometimes booted, but fail to enter windows. I used 1.28-1.3V since I didn't really want to damage the demo system on Intel's room.

Still, at 4.2 GHz with quad + HT that's definitely going to be better than a G3258 at 4.4 GHz. Looks like I might just have a CPU in my Christmas stocking this year. wink.gif

Voltage specifications for Broadwell are the same as Haswell (note that intel only provides ranges for vccin, not vcore). Also, Skylake is known to be able to accept more voltage. So I'd say the limit from broadwell should be around the same as haswell, about 1.4v.

Btw, when did you buy you cpu? Seems a "golden" broadwell, and it needs nearly the same as my 4690k (1.296v for 4.4GHz).

It might be that yields are getting better or BIOS microcode is as they typically do throughout the lifetime of a product

Thank you.

The OCs I did were quick and dirty but I was able to benchmark and test them for one round of x264 with no issues. It might be better yields, yeah.
I bought it just last week. Availability is on the rise in Europe for 5675C and 5775C.

How much influence do PSU and board have on stability in OC? Because my G3258 was "golden", too. I'm 2/2 now. Seems odd.

A good PSU is just a must in maintaining any stability. Haswell however typically couldn't care less what board you have as long as it can overclock their CPU's and has at least some sort VRM on the heatsink. Since the VRM is on the die having a high-end board doesn't play as much of a role unless you're going for clocks that most people will never achieve with normal cooling solutions.

Speaking from experience too since i've personally had dozens of 1150 socket boards with 4+1 phases all the way up to 16+ using the same chip yields the same results for overclocking within the slightest of voltage mainly to do some boards allowing for smaller incremental adjustments.

I have used nearly every CPU from Sandy Bridge on and Phenom II on. I have also used most GPU's from 2011 on, from low, mid and high. I've built 100's of rigs over the years. Most for fun and some for side work. If you have any questions and want an unbiased opinion, please feel free to PM me.

Alright, then I am just pretty lucky. nerdsmiley.png

Computerbase took a closer look at the 5675C (+ 6500 & 4690K) and it did well.

I've been linking this all over the place http://www.purepc.pl/procesory/test_procesorow_intel_core_i5_5675c_i_core_i7_5775c_broadwell?page=0,17

It seems the later the review has been carried out, the better the results. BIOS issues maybe?

Yes it did it makes me glad I built on z97 and saved the money.
