Unstable Rampage IV

[Perpixel]

I just installed my hardware this weekend and I'm having a very hard time with getting a stable OC. Here is the list of parts,

i7 3930k
Rampage IV Extreme
4 Corsair Dominator GT 4gb (16gb total)
3x GTX 580
2x Corsair Agility 3 120gb in raid0 for the system
2x Seagate SATA 7200 raid0 for data
Corsair AX1200

All of this is watercooled

The system run just fine with default setting but just trying to set any kind of OC using the EZ oc stuff to get 4.0ghz fail. The system boot fine but running prime95 few second make it reboot.

I also did try to load the Normal and Gamer OC profiles but it resulted in the system trying to boot a few time and shutting down.

After all the fail I disable all the GTX 580 but 1 and unplugged all the hardware I dont really need thinking that maybe the AX1200 didn't provide enough power but this still doesnt work.

My previous PC a with the same HDD, graphic cards and PSU was running just fine before with plenty of OC.... Where should I start?

thanks!

Did you check out othe Rampage Iv Extreme Overclocking GUIDE?

Here:

Easy Guide: http://rog.asus.com/forum/showthread...verclock-Guide

Advanced Guide: http://rog.asus.com/forum/showthread...r-Overclocking


I suggest you take a few minutes and read these guides. Start with the easy guide. There is a ton of information in them and step by step instructions to get a good basic overclock. Then come back with questions after you've tried the basics.

I'm really not interested in any of these just yet. Just running the cpu level up in AI Suite make the system fail.

You asked "where should I start" and I gave you some things to look at. Those guides contain not only BIOS settings to be used for manual overclocking, but cover other important aspects as well such as cooling, use of XMP or not for memory, use of the Rampage tweak mode, etc, etc, etc.

Telling us your system is unstable when you "run the CPU level up" doesn't give us enough information if you are not familiar with the basics of overlocking.

Are totally sure your default settings are stable? Did you stress test under default settings?
What specific memory model are you using?
How did you set memory timings and speed? XMP or manually?
How is your cooling? What are your CPU temps? (saying water cooling everything is not enough info)

Also keep in mind that the Automatic Overclock settings in the BIOS are not always perfect. Every system is different and those Pre-Set Overclocks are not guaranteed to work. The Gamers Profile in particular can give many systems trouble.

The best way to overclock is to:
1. Make sure your default is totally stable by stress testing, and
2. Reading the guide and making your own small incremental adjustments

Mdzcpa is totally correct here. You need to post much more information if we are to help you get a stable system. Also you need to learn abit about the topic yourself as then you will understand why we are saying try this setting, test this, try that etc.... The more you take time to learn the better you will do when it comes to clocking these CPU, Board and memory combinations. The platform has alot of clocking headroom to unlock but it takes time to learn evan for experienced overclockers.

The ram you are using please post the exact part number for me will you.

Two kit of those,

I did the XMP thing
PCIe to gen2 thing

I will try to manual OC but seriously right now im more in the realm of are all the cable providing power or is my motherboard broken. I'm not right to think that those Auto OC like the CPU level should just work without any additional configuration in the bios?

Two kits of the same RAM can have differing specs. These modules are certified for use on Dual channel systems this is a quad channel system. The Auto overclock is not 100% fool proof anyway but in this situation with non certified RAM it becomes evan less likely. I would run Memtest at stock settings with XMP enabled, Rampage tweak set to mode 1 VCCSA at 1.2 and VTT at 1.2 and memory voltage 1.55v. I have a feeling the memory is erroring and this will be accentuated with any overclock. Remember the memory controller on the CPU is essentially a 1600 mhz controller, yeah it will run 1866 no problems I can get over 2500 stable but it takes some adjustments.

[Perpixel]

I ran the memtest with no error. And I did try to manual 1600. I'll try those setting you have. Its really not helping me that everything run perfect if I dont OC the CPU even when I run the memory at 1866. I have some 1600 Dominator stick I can try too.

Also about the Easy over clock guide, somehow the multiplier is locked to auto. I cannot change the value in the bios.

Sadly you are not right. Those profiles will work if you are using ram specifically for the board.

And you are not alone in thinking that all ram is the same by the way, Many many people seem to think that because something is DDR3 it will work perfectly in all platforms. That is not the case. Different platforms have different ways of working with the ram. Just think about it. The first DDR3 ram I used on my X48 motherboard, needed 1.85volts just to boot. Those days the North Bridge managed the ram. Now that is done on the CPU and we have lower power requirements.

Each chipset has its own unique way of dealing with ram. Each chipset will prefer certain types of DDR3 ram. SB did not like the Hyper chips for example. The fact that some of the hyper ram cost like $500 per kit mattered not one jot. The platform preferred much cheaper kits and out performed their expensive brothers.

Take that with the fact that no two kits of ram are the same. Even if they are the same brand and model. Just no way to be sure that the batch of chips and the internal programming is the same on both kits. The primary timing will be the same, the voltages needed as per the model specification will be the same. But the sub-timings may be very different. And they might not behave the same way.

So when you set a default profile it is impossible to legislate for all kinds of ram combinations, what they do is work on the basis that the ram used is a binned kit applicable for that platform. Your ram will work perfectly as a dual channel kit on a Sandy Bridge board I am sure. But on at quad channel X79 no such confidence.

Can you get it to work, Yes you can.

How you do that is by taking the time to read the guides and find what works best for your set up.



I see that 8Pack has replied too.

As to why you can not access your multi, um what have you set as your means of over clocking. You will need to select manual to change any settings.
