Non-Z motherboards + G3258 + Windows 10 + Overclock = Fail (Windows update KB3064209)

[JPERT]

There is no way to overclock a Pentium G3258 on my MSI B85M-G43 (Nor on any non-Z motherboards) since windows update KB3064209 (Integrated into windows 10)

The symptoms : any variation of the multiplier coefficient (even if it's only 100 Mhz) will cause a bootloop until you put frequencies back to stock.

Bios is updated to latest version.

I bought this processor because i was confident i could overclock it a bit, otherwise for the same price i could have had a 3,40 ghz instead of this 3,2 ghz.

It was overclockable under 7 and 8-8.1 IF you passed on the KB3064209 update. But in windows 10, you simply can't.

As you can also see if you check this reddit i'm not the only one : https://www.reddit.com/r/buildapc/comments/3f3mro/discussion_psa_windows_10_currently_not/ https://www.reddit.com/r/buildapc/comments/3f3mro/discussion_psa_windows_10_currently_not/

(People with Z boards having problems resolved them with BIOS update, but the other boards need a rollback of this crappy update you did.)

If it's unintentional i'm hoping for a fix when you figure it out.

If it was intentional in order to push people into Z motherboards and higher processors like i3-5-7 then my next build, and the one after that (etc ... you get the point) will be full AMD.

If you want people to overclock only on K processors and Z motherboards, then don't release a product like Pentium G3258 to begin with, and don't push shitty update retroactively to make matters worse.

It's just bad marketing and in this day and age you will not get away with it and it will show on financial results.

Ok nevermind, seems that non Z motherboards were never meant for OC and their OC capabilities just were some kind of hack that got "nerfed".

Good to know, apologies for pointing at Intel.

RESOLVED.

Some backstory as I understood it.

1. Asus exloited a bug allowing basic overclocking on non Z chipset

"ASUS does not guarantee that Intel new Pentium processorand Core K Series ('Haswell' and 'Haswell Refresh') processors will be overclockableon ASUS H97, H87, B85 and H81 Series motherboards in the event that Intel issues software and firmware updates that result in function changes."

2. All Motherboard manufacturers copy it

"Customers will not experience the same level of overclocking performance on non-Z sku platforms. Intel Z87 based platforms are the only platforms that support BCLK and memory overclocking, in addition to processor core multiplier overclocking. Most H87 and B85 based platforms are not designed to be overclocked and may not have sufficient margin to provide a stable overclocking experience."

"Intel plans to release a microcode update that limits processor core overclocking to Intel Z87 based platforms WW30'13."

3. Intel fixed the bug and push via Microsoft (KB3064209/Win10RTM)

My problem with this stupid decision is that the "exploited BIOS" didn't affect stability. I can run video encodes for weeks straight whether I'm OC'd or not. And the other part to this is that I can't install Windows 10 even if I'm NOT overclocked.
