Aurora R4 a06 BIOS Overclocking
I updated my system's BIOS from a05 to a06 last night and am now unable to edit many CPU properties.
In particular, I'm now unable to modify any CPU multipliers.
I do not have a "K" processor, but it should be theoretically possible to overclock my i7 3820 to 4.3GHz by adjusting CPU multipliers on each core.
I am able to modify the CPU gear ratio (base clock) setting. Pushing this up a notch to 1.25 instead of 1 resulted in a machine that wouldn't post (all fixed now).
- Is it at all possible to overclock an i7-3820 via the a06 BIOS?
- Is anyone able to offer up any solutions as to how I can perform an overclock via the a06 BIOS?
TL;DR: I'm unable to overclock or alter most of the settings for my i7 3820 using the a06 BIOS on my Aurora R4. Is overclocking in this way now disabled on these machines, or am I doing it wrong?
System Information:
Model: Aurora-R4
Windows 7 Home Premium 64-bit
BIOS ver: 04.06.05
Processor: Intel Core i7-3820 @ 3.6GHz

There are numerous factors that can contribute to internals overheating, e.g. removing my R4's PCI shroud yielding lower GPU temps overall. It seems strange to me that Alienware would remove such a feature whilst presenting themselves as a friend of the hardcore/enthusiast PC user. Given that there are countless examples online of people overclocking i7 3820s successfully, this seems to open up the possibility that the decision to remove this overclocking functionality from the BIOS stems from other contributing factors, such as case design and air flow, the motherboard, or an aversion to dealing with tech support calls from people that got it wrong, for example.
Luis, I sent an email to the address you posted, explaining that providing you with my phone contact information was potentially a hassle for you as I live in Tokyo. In the email I explained that I had attempted to contact Alienware tech support via phone and chat, but, not speaking much Japanese, was unable to come away with any answers; the Dell website restricts access to any support methods outside of your home country...
Despite all this, the reply I received suggested that I contact Japan support again...
In much the same way that one might purchase an iMac and not an all-in-one computer, I'm starting to feel like I've definitely purchased an "Alienware" and not a PC.

My guess is you are right. First off Dell sells the overclocking and they also must replace damaged systems in warranty. If it was me I would lock the BIOS and only allow overclocking for the customers that payed for it and only within the limits set forth. Of course it could also just be an oversight that needs to be corrected.
Motherboard makers that make a BIOS that allows it has nothing to lose. You will almost never ever damage a mobo by OC'n. When you sell and support an entire system then it's another story.
You may not be a noob but they are out there and it is very easy to damage a system if you do not know what you are doing. Heck, even if you do it can go down hill fast.

Answer me now!!! Really? Why not be nice
Anyway, Dell sells the Aurora with the 3930k in two configs. 3.9ghz and 4.1ghz. Which config did you buy? It wasn't the 4.5ghz. If you want to tweak it then do it with the the turbo and then kill the power management buy putting it on high performance. It will keep it at the clock you have it set to.
You do not use Windows to tell you the clock, it never will. Download CPU-Z.
Dell charges for the overclock like everyone else. If you payed for it then they will make sure it runs at that speed but to complain about a 4.5ghz overclock they do not sell and you did not buy is wrong.
Of course you could always go back to A05 or wait and see if it was just an oversight.

Indeed.
After reading Luis' response that touches on the reason for the removal of various overclocking functionality from the BIOS, I'm obviously not expecting any solutions here, and I agree that it makes perfect sense to limit this functionality from a economics perspective, but it seems kind of presumptuous to remove features like this based on a default position that "they'll probably break it". I don't know, maybe this is has been a huge issue for Alienware in the past.
Also, as far as I'm aware, you can't rollback to a previous BIOS.

I would try rolling back if it was me but don't hold me to that. If it fails it is on you. You should also have the option of doing the OC through the turbo.

Hello Dell/Alienware,
Please eleborate more on what the above topics meant? This is from Dell website page (http://www.dell.com/my/p/alienware-aurora-r4/pd). Go to Tech Spec --> Under Chipset.
This is what my expectation when receive my Aurora R4 with 3930K last month where onboard is bios A05. This beast was running great no problem at all.
I also did OC all the cores up to 4.5Ghz with my aftermarket CPU cooler proven to make the temp under control (below 70 degC at full load).
However, During my upgarde the Bios to A06 (Bios to be said for Windows 8 compatibility) has removed the unlock portion for adjusting core multiplier.
Since that also my system cannot detect my SSD (Crucial M4 512GB SSD).
All above problem is originated from the BIOS A 06. Now when I complaints about this problem, what you all do is telling me:-
1) Saying my setup problem (SSD) . Now proven it was not wrong.
2) Saying the OC is there only it reset because I was updating the Bios. No its not. Its locked.
3) After that saying that only K version CPU able to overclock. But mine is K version. Whay can not?
4)After all above answer, now you're saying the OC function is not advertised? Is that true?? Can you click the link I provided and eleborate further?

Judging by the response I received (or lack of a response, rather) after emailing the social media address listed above, I doubt we'll be seeing any solutions to this issue.
