Any more motherboard models that could be used for "Non-Z overclocking" Pentium 3258?


P.S. Please note more than one person has had difficulty changing the multiplier on MSI boards from Auto to a multiplier higher than 32 due to the counter-intuitive method used in the BIOS. If you think you cannot change your multiplier on your MSI Non-Z board please read this post ---> http://forums.anandtech.com/showpost.php?p=36561735&postcount=114 .

Asus has bios support for their non-z boards. Just updated my bios to support the new pentium g3258.

Are you able to change the processor multiplier to something above 32 now?

Don't own the g3258 at this time. Debating whether to buy the g3258 or I3-4150. My m/b only has 4 power connectors rather than the 8 so I am not sure how stable overclocking would be.

I remember I saw a post show msi can also oc with their h97 motherboard

and I think not only asrock, asus, gigabyte also release the new bios for the g3258 cpu

I haven't seen that post, but here is an August 2013 video showing MSI B85-G43 Gaming board Non-Z overclocking:

Regarding the MSI boards with Non-Z overclock, I'd have to imagine that feature is still enabled today based on this June 2014 facebook post from MSI:

"Did you know that ‪#‎MSI‬ H97, H87 and B85 motherboards could also OC the new Devils Canyon Intel CPU’s? Overclocking is no longer limited to Z97!"

However, I would prefer to get confirmation from actual end users (or reviewers).

Asus H97, H87, B85 and H81 Motherboards Can Now Overclock Intel Unlock Processors

June 18, 2014

Asus has recently released an announcement informing us that their latest H97, H87, B85 and H81 Series motherboards has now the ability to overclock 4th Generation Intel Haswell Core K Series (unlock) processors, including the Intel Pentium G3258 Anniversary Edition processor. The announcement didn’t specifically mentioned “Devil’s Canyon” but used the term “Haswell Refresh K Series” which is basically the Devil’s Canyon. Does this mean that Devil’s Canyon is fully supported on the older Z87 Series motherboards and can be overclocked as well? I guess Asus can’t guarantee that as well. Check out Asus’ announcement below, specially the “notes” section.

Asus-H97-H87-B85-and-H81-can-now-Overclock-processors-1024x338.png


ASUS today announced that its H97, H87, B85 and H81 Series motherboards are able to overclock the latest Intel® Pentium® Anniversary Edition processor (G3258), 4th-generation Intel Core™ K Series (‘Haswell’) and new 4th-generation Intel Core K Series (‘Haswell Refresh’) processors. The combination of the Pentium Anniversary Edition processor and non-Z chipsets represents the best choice for mainstream overclocking, delving both great value and superb performance.

The overclocking of the Intel Pentium Anniversary Edition processor, 4th-generation and new 4th-generation Intel Core K Series processors have traditionally been limited to Intel Z chipsets. With ASUS H97, H87, B85 and H81 Series motherboards, performance enthusiasts are now able to exploit the overclocking power of those processors via the award-winning ASUS UEFI BIOS.

When a compatible Pentium Anniversary Edition processor, 4th-generation or new 4th-generation Intel Core K Series processor is inserted into an ASUS H97, H87, B85 or H81 Series motherboard, the CPU’s overclocking potential will be detected automatically and the related tuning items to adjust the CPU ratio will appear in the UEFI BIOS.

I wonder what kind of voltage adjustment will be provided to those that own a low end ASUS H81 with three phase VRM?

For a Pentium 3258, I'd imagine allowing extra voltage would be fine for three phase VRMs since there are only two cores to supply.

My Asus H81 m/b only supports 3 phase so I am not sure how extreme one can go on o/c'ing. I decided to go with the I3-4150 since I was able to price match and I have a few to many background stuff running while I am watching tv on my computer. I am not sure if I want to risk my parts by o/c'ing at this time.

Besides I had to update the bios anyways to support the Haswell refresh cpu's.

Asrock H97 Performance. Pushed my 4770 up to 3.9GHz, can overclock K models too.

Thank you very much for letting me know about that one.

Now for ASRock’s really clever trick, within the UEFI under the OC Tweaker section we find something that we shouldn’t! An overclocking menu for the CPU, rather cleverly named Non-Z OC. And this allows you to overclock your multiplier on a Non Z based board, clever eh!? This is actually exploiting a loophole in the architecture that was reveled by Intel sometime ago, and to be fair it could be closed via an update to the chipset code or via change to CPUs in the future. But for our Intel 4670K, it worked like a dream…

For two cores, It would probably have worked fine for some decent overclocking under the 95 watt stock cooler. This provided ASUS made extra voltage for the CPU available in the BIOS

Example: Asrock Z97M Anniversary only has three phase power delivery as well (No heatsink on the VRMs either)

Wait, you overclocked with a non-Z and a non-K? 3.9GHz is the max turbo for a 4770 non-K. So did you just turn up the turbo to the max?

This isn't a case of raising the bclk slightly either, is it?

And now that I've tested the GA-B85M-DS3H myself, I will confirm Non-Z overclockability with this board + F6b BIOS.

G3258 at 4.0GHz with an MSI B85-G43 gaming. Might go higher but I'll run it there for a while. I don't game but the price was right at Newegg. The video outputs came with covers on them but they do work.

Just kicked it up to 4.5; only thing I did was adjust the multiplier. Mid 60s running Cinebench with IGP. Will do some more testing this weekend.

Sweet I'll mess with that board tonight. What vcore for 4.5GHz? And do you have a good amount of voltage options?

I don't know- I literally changed the multiplier and tried it. I did flash to the latest BIOS at default setting first though. For $90 for the combo, i'm inclined to leave it where it is until some rainy day when I have time to play with it. Good luck with yours though; I'll check back to see how others do.

Just checked for you; if CPU-Z v1.69 is accurate, it gets unbelievably low at idle and as high as 1.224V with 100% load both cores at 4.5GHz. Temps 62 and 67 per Realtemp v3.67.

For some laughs I decided to mess around with the ASROCK H81M-HDS since I'm probably going to use this mobo for my HTPC. Anyways, this badboy seems more rock solid than the MSI B85-G43 Gaming mobo. Currently priming my best chip batch 3418B976 4.5GHz @ 1.3v (I'm thinking I can drop the vcore some more).

Tried a G3258 on an MSI B85M-G43 with latest BIOS (3.7) and no joy. CPU ratio control is locked and the processor can't be overclocked.

What does Non-Z refer to?
"Z" in this context refers to Intel's overclocking chipsets, Z68, Z77, Z87, and Z97. Some manufacturers have enabled oveclocking on "non-Z" boards, which traditionally was not possible except in a very limited number of cases.

I can now verify that the Gigabyte H81M-DS2V will overclock the G3258 as long as the BIOS is updated to F4 or above. In my case I went straight to F5. I'm curious to see if this ability extends to other CPUs as well, my suspicion is that it will not. Another observation is that the G3258 booted up fine with the non-overclocking F2 BIOS, but until it was flashed to F5 the multiplier could not be adjusted. I performed the BIOS update using the G3258.

Have you tried overclocking yet?
