Hello all, first post
No idea if there will be interest in this strange chip but hey, thought I would share my experience.

I was planning on going all out on my z97 based rig since skylake came out I thought well I might as well go crazy, get all the new shiny things and then leave the computer alone (yea right)
After watching the TR podcast with David Kanter I was surprised by the benchmarks, whats this little ginger runt clocked at 3.3ghz doing alomst par and even beating the latest and greatest chips in gaming based benchmarks....I enjoy playing with new stuff and the computer is for gaming and media so those benchmarks were ment for me . Since I could actually find one to buy and it was almost the same price as a 4790k so I figured why not.

Flashed the latest ASUS bios and it booted perfectly, then it got strange, it would only run at 3.7, no stepping up or down, constant 1.12v....huh... I tried some overclocking and nothing would stick....x40 in the bios but still 3700 on the desktop (8-40 in cpu-z)
Dug around on google and then used the bios flashback (computer powered off) to flash the earlier bios that supported the new chip and hey look at that it worked great, all features working fine, I girded my loins one last time and re-flashed the latest bios, cleared cmos and hey-presto its all a go go.

Overclocking was less interesting but still intriguing. I will admit im a very lazy stability tester 30 mins in occt and some pov ray and im happy enough.
It went to 4.1 on all cores happily enough with 1.210v, 4.2 on all cores was around 1.35 and it wouldnt even post at 4.3 with 1.4 up it, i tend not to abuse brand new things so I left it there.
A nice-ish compromise was with all the speed step jazz, c states, adaptive voltage on was a mixed bag of per core adjustments 43-43-42-41 single core pov ray is about 1.28 and mixed workloads are like 1.24 maxing out at around 52c (h100i)
Cashe ratio and voltage didnt seem to help in the slightest but I may be doing more tinkering there. Didnt touch memory, not my thing (dont know how), 1600mhz bog standard

Interestingly, and correct me if im wrong but occt linpack is an avx type load right, the one you avoid with adaptive voltage on haswell because the FIVR asks for an extra 0.100v or something like that? Well this chip doesn't do that, tested with prime95 too, again same voltage I put in and no more. Is anyone actually surprised at that or did I not get the memo?

Thanks

Thanks for sharing your experience. I'm current trying to source the Broadwell i5, but it's either overpriced by 100 USD or not in stock

This will be along with the 80186 and i860 one of the shortest lived desktop Intel CPUs.

Maybe not the greatest example; the 80186 was produced until 2007 (for embedded systems)

I did say desktop. The only PC I'm aware of that used the 80186 was the Tandy 2000.

Although, IIRC, the 80186 also wasn't really intended for desktop applications, more for embedded. Run your elevator or your spaceship (no, really, that's why Intel made them until 2007), not your desktop.

It's just that a couple PC makers decided to use it for desktops anyway. The resulting machines tended to have mediocre PC compatibility, though, because the 80186 had its own embedded chipset that was incompatible with the PC. (The sole exception is the HP 100LX/200LX, which uses the 80186's CPU core design, but with PC-compatible hardware in the SoC.)

Double-posting, I know, but looking into things... this is just odd.

http://www.xfastest.com/thread-159434-1-1.html has leaks showing that the P1+ tier (which is above P1K (i7-6700K)) belongs to i7-5775C through 2016 Q2, MS2+ tier (which is above MS2K (i5-6600K)) belongs to i5-5675C through 2016 Q2. Basically, this thing isn't going to be short-lived, but it makes things tricky. Buy Broadwell-S and get better gaming performance for less TDP, but a worse (Z97) platform, or buy Skylake-S and get higher TDPs and slower performance (especially if you're looking at an i5-6600K, where the clocks are quite a bit lower), but a better (Z170) platform?

Then, there's this leak from June of the Kaby Lake lineup for 2016 2H... which shows that a Skylake-S part with eDRAM is going to launch with the Kaby Lake parts. And, given that Kaby Lake is going to be a second GPU tock apparently... well, at least Intel knows why people want an eDRAM -S part, but still, just odd product positioning. That leak also implies that Kaby Lake will come with new desktop chipsets, but no new mobile chipsets.

That may include the Pentium III 1.13Ghz.

Don't know if Intel every rereleased it. I just know they weren't all stable and they recalled/pulled a lot of them.

They did rerelease it under a new stepping of Coppermine (cD0), then again under Tualatin.

QZ64 and SL4HH were the bad cC0 stepping, QEJ1, SL5B2, and SL4YV were the good cD0 stepping. (Also, the cC0 step 1133 MHz parts were slot 1, the cD0 step parts were Socket 370.)

And I the second to say Welcome!. I didn't even notice that was his first post.

By bad stepping if you mean "factory overclocked and not running stable under stress tests" than you're correct. Those series of articles are what led me to Tom's Hardware... Which now just looks like a jumble of ads =[

And if by "stress tests" you mean "running GCC" - we're not even talking something like Prime95, even!

Thanks for the welcomes, as for rest of the hijacking going on, nice to meet you guys too
