Overclocking i7 920 on an Asus P6T Deluxe V2

Hi All,

So, I have an old rig that I have lying around as my Windows 10 test/bitch PC and I am trying to keep it in a useable state.

As the title suggests, it has an Intel Core i7 920 chip (D0 Stepping I believe. As I understand it, the D0 chips don't need as high of a voltage to OC as the C0 ones do/did) with an Asus P6T Deluxe V2 board in it. Also have 12GB (6x2GB sticks) of G.Skill RAM in it. Also running 2x150GB WD Velociraptor drives in it and an EVGA GTX 570 (Stock). CPU is being cooled by a Noctua NH-U12P SE2.

Now, I've tried to wrap my head around what I need to do with regards to trying to overclock the i7 on it but I've never really had much success. As the PC sits, it's currently at stock settings.

My latest attempt has managed to get the rig to boot with a 3.7Ghz overclock, but for some reason the system would only detect ~4GB of the installed RAM. I have been trying to hunt around to try and find someone with a similar set up to try and compare what they are using as a guide but can't really find anything that useful (Anything I have come across has been so convoluted/confusing that it makes the whole process seem like a headache).

Since I am a newbie to the OC3D forums, I thought I should throw it out there to see what people think or can suggest for me.
 
Welcome to the forums!

Does it only detect 4gb in the bios or did you install a 32bit windows?

Thanks mate, but yeah, it only then picks up approx 4GB in the BIOS. The O/S that's currently on the machine is the latest test release of Windows 10 64-bit (Don't worry, I am experienced enough not to make that rookie mistake lol). But back at stock settings, the rig picks up the full 12GB.

That is really weird, granted the memory controller is on the cpu which might not like the oc all that much but wtf. Tune the oc down to the point where it detects all memory again, then maybe losen the timings and lower the frequency on the memory, and try to go back up slowly with just the baseclock frequency.
 
Yeah, see, that's the thing though. Choosing the right settings is what's messing me up. Especially with this older board. Like, I've managed to OC my current rig quite easily but this older one, there are quite a few things that need to be changed and I'm not 100% confident on all the stuff I'm messing with. I've been trying to find someone with existing settings that I could use as like a baseline that I could punch in and see how it goes. I sense it's not going to be as easy as that lol
