Haswell Overclock Thread

Older versions of AI Suite crashed regularly but did work. This one was a pain to install, but has been flawless since then.

I've reset the board back to optimised defaults. I'm going to return the CPU, I think it's a dud.
 
One thing I don't get is how the temps are staying in check at higher voltages. CPU-Z agrees with AI Suite about the voltage, which is also the same in the firmware. At 1.36v it was sticking around 80C, I thought it'd shut down on an air cooler at that voltage.
 
Try 4.6 with the same volts and see if it's stable

Also ai suite 3 works great. I have changed voltages and multipliers mid-prime with no issues.

And the fan control is amazing. Lots of control
 
I think I'll just send it back. It's within Amazon's 30 day policy, so I'll be able to get a replacement before I send this one.

I used AI Suite a lot with my Z68 board. The fan control wasn't as good as with this board, but it was good for keeping things quiet. When this is idle, the fans are so slow they are literally silent.
 
Ha, mine still go but I can see them turning rather than it being a blur. My PSU fan hardly ever comes on, never at idle, so if my HDD is suspended, the PC makes no sound at all.

His getting a replacement first before sending it back. So he got a choice which one to send back after. Best to do more testing with ur current one so you know the limit before replacement arrives.
 
Btw, looking over ur screenshot, I notice you are in adaptive mode. With adaptive mode it would bump the voltage up to 0.12v during stress test. You should be overclocking from manual then set the voltage to adaptive after for normal use.
 
Yeah, the board does internal tests to decide what voltage to use, and it's decided it needs 1.28v for stock turbo clocks, which is higher than it should be really. I haven't done any proper stress testing. If the replacement was worse I'd keep this one and just run it at 4.4GHz max.

That's what the board sets on optimised defaults. When I did it manually, I fixed the voltage and still had stability problems without voltages over 1.25v.
 
I'll try doing a stress test of an hour or so tomorrow when it's a bit cooler to find the minimum stable voltage for 4.4GHz.
 
Can anyone tell me where the BIOS setting is for the equivalent of Adaptive OC Voltage in Asus Suite 3 is? I've got a Z87-Pro with the 1205 BIOS, and AI Suite insists on running a lower clock and a higher OC voltage, and keeps resetting my values between boots.

It very annoying because I'm getting more more voltage and heat, but less speed, and the AI Suite makes me reload my correct settings at every boot. I presume I have to set what I want in the BIOS, and although I can find the CPU ratio I need, I can't find the OC Voltage to lower it.

Any help appreciated!

Edit: Doh! I found it just after I posted! It's under the AI Tweaker, but you have to change the CPU voltage from "Auto" to "Adaptive" in order to get the correct fields up. Now AI Suite boots with the correct settings from the BIOS.

I had a play with the settings, and the board got it pretty much right. At 4400MHz anything under 1.36V boots but randomly crashes. It seems stable generally at 1.372v (I haven't done any extended stress testing), but temps are going to reach 80-90C immediately under load.

Sounds like a poor clocker, that's far too much voltage for that speed. You'll probably need to go down to 4.3 or maybe 4.2. 80-85 under load (e.g. AIDA64 stability test) is about the max you should push it to really.

U still using adaptive mode for overclocking? U should be using manual for now.

Personally interest, whats the batch number for ur chip? L3**B*** and made in?

Yeah, my tests yesterday showed it needed 1.28v even at stock at load, so I'm sending it back. I've worked out what this one can do in case the replacement is even worse.
