'MSI X79A-GD65 8D M/B' and 'Intel Core i7-3820 3.60GHz (Sandybridge-E)'


I'm extremely confused with the settings and how to overclock...

I've read the guides and others but still confused :s

I can change the CPU RATIO to: x40 (4GHz)

without touching anything else and all seems to go fine but surely there should be other settings that need changing...

Can anyone who has experience with this board give some advice and what else I need to change?

The settings on this new mobo are completely new to me, compared to my old GA-965P DS3P :/

ThanX
 
I don't have that board, but I know to get the best clock from that 3820 you need to set the bclk to 1.25x bclk.

I'm sure someone with the board could tell you in seconds where the option is to do it.

You mean 125MHz, and whilst you need to do that to hit above 4.5GHz~, you can quite easily get up to around 105x43 (4515MHz) before needing to play with the BCLK straps.

I've also posted this about a million times, but this is an excellent SB-E overclocking guide (makes no odds what motherboard you are using, as 99% of the BIOS options will be the same, even if they are named slightly different things) http://www.overclock.net/t/1189242/...anations-and-support-for-all-x79-overclockers

Edited. And yes, true max multi is 44x. I've been considering this chip for a while now.
 
I would read that guide. I just did, it is very good. But short answer is yes. Keep an eye on the temps though.

That guide suggests some cpu voltages for different overclocks. Safes time when someone else has taken the time to document everything.
 
Thanks...

I looked at this guide yesterday and couldn't get my head around it :(

I'll take another look and grab all my manuals to compare...

a lot of the settings RE: Voltages are AUTO on my board, is it or would it be safe to leave as AUTO?

ThanX AgaiN
 
You'll need to specify manual voltages (or manual voltage offsets) for overclocks beyond a certain point. My CPU is happy with AUTO voltage to around 4.4GHz, but beyond that I need to manually set them, plus the all important LLC (load line calibration) and CC (current capability) values.

The i7-3820 will only use up to a 43 multiplier. You can set a 44 multiplier, but it won't ever throttle up above 43 (mine won't anyway).
 
Must say, I do understand where you are coming from to a degree OP.

There are soooooooo many options on these boards. And comparing this Rampage IV Formula to the UD3 I had before, it's just mental how many things it gives you to play with.

Not sure what the MSI is like, but these high end Asus boards are very intimidating.

But most of it can be ignored my us common folk, and for a mild OC like you went for, ir will often not be necessary to change anything other than upping the multiplier.

Just because all those options are there, doesn't mean the need to be used - though I personally will be playing with all those extra little bits. This board will keep me entertained for years! :D
 
I think I will take it as far as I can without having to mess with voltages, just change the CPU Ratio...

Not sure what im going to do about overclocking my RAM (Kingston HyperX Genesis 16GB (4x4GB) DDR3 PC3-12800C9 1600MHz) and my GPU (VTX3D HD 7850 2048MB GDDR5 PCI-Express CROSSFIRE Setup)... LoL :/
 
Just take your time.

And to be honest, if you are new to all this, then just run the system at stock for a while and get used to it.

All this overclocking can become quite frustrating should you become obsessed with getting everything just the little bit further...

I desperately wish I could stop myself fiddling and just kick back and play games and enjoy :)
 
It's all the different settings on this new mobo which has got me...

On my old Gigabyte Board it was simple but this is just a different ball game....

I really do want to overclock my GPU though as it overclocks very well from what ive read but I will cross that bridge when I feel safe to do so :(

Thanks...
 
Shane, as you know I have pretty much the exact same set up as you (CPU, RAM, GPU, MB).

I've been able to lower my CPU core voltage from 1.200v to 1.050v at stock 3.6GHz. I also tested 1.200v at 4.4GHz and left it for 20 minutes without any problems.

Temps @ 3.6GHz - Approx 28, 29, 29, 31
Temps @ 4.4GHz - Approx 34, 35, 36, 36

^ Those figures are from memory.

I'm sure you should get similar results. :)

I prefer stock clock settings with the 1.050v (or 1.055) with the lower temperatures tbh. I can barely notice the difference between 3.6 and 4.4.
 
^ Additionally, I'm thinking about buying a water cooler for the CPU. Apparently we can get below 30 (maybe 25) degrees with a good watercooler running at 4.4GHz. Just make sure the voltage is 1.200 or above mate.
 
Don't knpw wheather this thread is still for viewing but I bought a overclock bundle here the I7-3820 and MSI X79A GD65 (8D) and lost the overclock to a bios update. The staff gave me some settings but not all. Played and played found if you go into the OS overclock facility not the double click - have a moderate overclock - tweek the drop down menu for the strap near the top and usual apply etc., I now have 1.3 instead of 1.0. Now the world opens up.
