So apparently you can't overclock the g3258 on an Asus H81M-K. Even tried bios modding it, managed to unlock the ratio multiplier, but the cpu speed was still stuck on 3200mhz.

With nothing to lose, I crossflashed the H81M-C bios on it. I was fairly sure it would brick, but everything seems to be working so far.


Time to fine tune it then I guess.

EDIT: In case new users stumble upon this. I used UEFITool to unpack the C bios (3501) and force flashed the rom using a special version of AfuWin64 and the following command in cmd.(yes I flashed it while running windows)
afu64.exe H81M-C-3501-unpacked.rom /GAN

Restart your PC now and go into your bios, it should now say H81M-C at the top and you should be able to go past the 32 multiplier and change all kinds of voltages.

Made a small package containing the afuwin version and an unpacked C model bios (3501):

Are there any problems ...which Asus H81M-C bios did you use? I own several of these boards & assumed (stupid me) when I bought them, I would be able to overclock the Intel G3258 CPU too.

Nope everything's fine. Sadly my chip is more on the lower end, requiring 1.25v for 4.2ghz stable.

I'm using the latest C model bios version, 3501.

I unpacked it with UEFITool_0.22.1 to get the .rom file. After that I used a special version of AfuWin that allows you to bypass/ignore all secruity checks and force flashed the unpacked rom while running windows (using cmd).

Gonna add a package to this post, including the AfuWin version used aswell as the unpacked C bios.
EDIT: Getting an error whenever I try adding a file to this post, so here's a mirror for now: http://www.mediafire.com/file/g8yhp5vbgciqvtm/AfuWin64%20and%20H81M-C%20bios%20%283501%29.rar
Close everything then flash the bios using cmd (as admin) with the following command: afu64.exe H81M-C-3501-unpacked.rom /GAN
Restart your PC after that and go into your bios, it should now say H81M-C at the top and allow you to go past the 32 multiplier etc.

Thanks so much for the info ...I was really frustrated that I couldn't find a solution myself. I recently discovered that the Asus H81M-E motherboard does support G3258 overclocking which is ironic since when I went to purchase a few of them ...they had recently sold out. mad.gif Hopefully though ...stock will be replenished soon.

Well since no replies ill assume my best bet is finding a cheap z97 board eh?

Just picked up a g3258 off ebay for 35 bucks, not sure what they are going for but half price of new sounds about right.


Second question, does the 3258 IMC have any problem with faster ddr3 ram? There is a 2133 kit on my local craigslist for cheap.

Hey guys all z97 boards should support the g3258 without a bios update right? I found a mint condition msi krait for 60 bucks shipped, curious to see how far my 125 dollar setup can clock to

The cheap msi H models can overclock it. I had one of those, the vcore limit is 1.4 so you cant go above it though. I managed to get 4.9ghz on that cheap msi board.


Is anyone still using the g3258 around here? Im trying to get it past 5ghz but it wont go past windows loading. Currently running 1.15volt at 4.5ghz, can do 4.8ghz at 1.325. I need some 5ghz settings.

I actually found a z97 board for 60 dollars, i had the 3258 for a couple days but i didnt trust it as there was artifacting on the onboard GPU as soon as you loaded a 3d game. On the lookout for a cheap unlocked i5 now lol. Even in WoW the thing was maxxed at 100%, 2c2t just isnt enough CPU for anything other than webbrowsing sadly.
