ASUS today announced that the latest UEFI BIOS for its motherboards based on Intel H87 and B85 chipsets unlocks previously inaccessible overclocking features for 4th generation Intel Core processors. Before this update, the overclocking features of new Haswell 'K Series' processors could be enjoyed only with motherboards based on the Intel Z87 chipset. Now, however, performance enthusiasts can exploit the power of Haswell K Series processors using ASUS 8 Series motherboards like the ASUS H87M-PRO and B85-PRO. The BIOS update is a free download for 10 ASUS motherboards - the H87-PRO, H87-PLUS, H87M-PRO, H87M-PLUS, H87M-E, H87I-PLUS, B85-PRO, B85-PLUS, B85M-E and B85M-G.

How much is the "overclocking" crippled?

Overclocking on Asus (and other brands') H87-based motherboards is definitely a great news for those who have already purchased one or are inclined/forced to settle for one. Whatever "extra" comes along is all good. But what about the rest of us who are still undecided? Will this BIOS update enable "complete" overclock-ability - like RAM as well? Or is it just gonna be the CPU? Is it gonna be as tweak-able as a Z87 model? Then where does it leave the Z87? What would be the point of getting a Z87-based board then? I'm not stating anything - just curious :)

Just going by the pictures of the two boards above. It looks like a 4+1 power phase system. Not exactly what one would want for an overclocking motherboard, though it should suffice for a small OC. Most Z87 boards have more/better components in this regard.

True

Hmmm, true. The heatsinks aren't that encouraging either :(

You think there may be some broken boards going back to Asus?, :ohwell:

I managed a good 4.4ghz OC on a cheapy 4+1 phase p67 motherboard and a 2500k, I'm fairly confident these will be able to deliver a similar overclock with HW chips, they're not aimed at serious/extreme overclockers, infact I'd have one over my shitty Gigabyte GA-Z77-DS3h which has K-multi overclocking but only auto vcore so I can only get 4.3ghz stable on my 3570k :banghead:

Did anyone notice the 5Ghz 4670k screenshot at 1.28v? Has ANYONE achieved this with Haswell?

I'm pretty sure the current record for Haswell is pretty close to 7GHz, but yes that is a damn low voltage for 5GHz.

Yeah, I noticed, and then I noticed that it is an ES CPU. I have given not a single...anyway...

:banghead:

Not that I heard of. Might not even be CPU voltage that is shown, could be cache(likely).

I heard that due to lack of hyper-threading, the I5s have a better "thermal headroom" (in the bad-heat-dissipation-due-to-22nm world), meaning more room to play around than the higher-end I7. So, 5GHz isn't impossible, but again, that would depend on the PARTICULAR cpu and the user's luck (more so than expertise for the holy Haswell I hear :( Everybody seems awfully quiet about this. Shouldn't Intel be facing loads of sh1tstorm everywhere???).

Same argument that I had in the other thread low power chips they don't need massive 8-16 phase pwm sections to push a normal clock.

I wouldn't really recommend it for overclocking, my one recently developed the disturbing habit of getting extremely hot around the 8 pin EATX socket (so hot that I'm surprised the solder near the socket only discolored instead of melting), I had to disable turbo on my cpu to get a temp that even resembled normality (its a core i5 4440). I've had to effectively throttle the amount of power it draws through the socket by using a atx 4 to 8 pin adapter on half of the PSU's 4+4 socket to get any semblance of normal operating temps. My old Asus P5K-VM didn't give me these problems, I had core 2 duos running at 4GHz without stressing the VRM at all (8 phase instead of 4 phase like the h87m).
