Intel Core i7-3960X Review
BIOS
Published: 14th November 2011 | Source: Intel | Price: £790 |
BIOS
We'll just be skimming across the BIOS for the Intel i7-3960X on the DX79SI as the processor bits are largely overclocking based. Despite the main base clock being 100MHz, as it was locked to on the Sandy Bridge line, there are some multipliers in play no so that you have a broader array of ways to get the CPU speed you desire. So here we have 1.25 multiplier for 125MHz BCLK and 1.67 multi for 167MHz. This frees you from solely utilising CPU multipliers to obtain your overclock.
Similar to the overclocking options available on the LGA1155, the LGA2011 allows us to adjust the turbo multiplier based on the amount of cores being utilised, as well as altering the maximum Amps and Watts that the CPU is capable of drawing upon.
Memory multipliers are still in play, although the combination of the Host Clock Multiplier and the Memory Multiplier gives us a larger choice of RAM speeds. Instead of just having 1333MHz, 1600MHz, 1866MHz and 2133MHz, which are all fairly large leaps beyond the abilities of most RAM kits, you can also have 1666MHz and 2000MHz. It's much easier to get a 1866MHz kit to run at 2000MHz than 2133MHz, or you can tighten the timings of a 2133MHz kit without overly restricting the frequency of your RAM.
In short, there are a lot of extra options available on the Sandy Bridge E than existed on the plain Sandy Bridge.

I'm getting SB-E. Intel delivers again 
if the future SR-3 has two of these babies on it..... where do i sign 
Great review Tom. SB-E is totally awesome. Wish I had the budget to build a SB-E system. One can always dream? 
Brilliant review as always. Amazing performance at stock and Intel have done it once again .
.
Wow, scoring 10 on Cinebench strait out the box is amazing, a 2500K @ 4.7ghz scores about 7.9 so that goes to show just how powerful this CPU is.
Also, 48,000 PPD at stock .... The only thing I have against SB-E is that it is still 32nm, power hungry and hot. The heat is to be expected but it would have been nice if SB-E was 22nm and a little cooler using less volts.
If I had money to burn i'd buy one but I think i'll hold out to see what IB-E is like.

OMFG what a chip Intel blows everything out of the water again!!! Great review as always Tom never got bored for a second keep up the great work
Awesome stuff, Shame its out of my price range.
I wounder how long it will be before some these hard core guys try activate those 2 other cores and see if the succeed.

i think 3930k is the best bang for your buck AND I WANT IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

.probably have to wait for x-mas to save some mooney .... but here in canada just the 3930k is ~600 dollar and the boards are 280+
Damn this is a monster

not sure if you watch your own vids tom???
after 35min er so your camera starts going dark/light/dark/light.......
and
yer mic's commin thru with a fair bit a white noise once that starts.......
may be time for a new one.....not like it owes you anything....its make HOURS of great oc3d goodness for all of us......
thanx again

Just waiting for cpus to be in stock, which doesn't seem to be anywhere.
Hehe
I love how this chip performes. Wonder how well the benches are when it is clocked.

Edit: And the i7 3960X is in stock at Overclockers.
The specs for the 3930k and 3960X are very similar so I don't understand why the 3960X costs so much more.
i7-3930K
- Core Size: 32nm
- Socket: LGA2011
- Six Core
- Frequency: 3.20GHz (3.80GHz TURBO)
- Multiplier: 32x (Upto 40x available)
- L2 Cache: 6x 256KB
- L3 Cache: 12MB
- TDP: 130W
- DOES NOT INCLUDE COOLER
- 3yr Warranty
i7 3960X
- Core Size: 32nm
- Socket: LGA2011
- Six Core
- Frequency: 3.30GHz (3.90GHz TURBO)
- Multiplier: 33x (Unlocked Multiplier)
- L2 Cache: 6x 256KB
- L3 Cache: 15MB
- TDP: 130W
- DOES NOT INCLUDE COOLER
- 3yr Warranty
The differences seem minimal to me, so why is the price difference so large. Will the 3960X clock higher or what?

The highest end chip is always the most expensive, despite not giving that much more. Also aria's dates slipped from 18th --> 29th so I'm probably going to hope scan or somebody else can provide. Aria are definitely the best for the motherboards as far as I can tell though.

Do you know what 24/7 vcore they suggest using?

mby they handpick the colden chips....thats why X series will cost more!

Here's hoping that a large sum of money magically appears in my bank account.

LGA 2011 is awesome.
it eats everything AMD has to offer for breakfast on consumer level.
be interesting to see if it beats the new 16 core AMD server chip based on bulldozer.
think it would tbh but still will be good to see if AMD can beat intel chips on at least one section of the market

1.5v would be for watercooling and people that understand what overclocking is about.

So there will soon be launched a SB-E with 8 cores? Theres some news about it on techpowerup. Looks like im gonna wait a bit longer before i purchase my new cpu.

I read that the C1 stepping have a few issues that might be fixed in next batch, so il think il wait a bit and see what will happend. Also, the IB-E is launched Q4 2012, and it is compatible with X79 MB.
Correct me if im wrong. the 8 core SB-E is only for servers?
Why no quick sync on the SB-E?
The 8 cores are the Xeons, they are mainly for severs and aren't really designed for desktop use they are designed for use in dual configuration on Server motherboards like the SR3. Just looked at the specs as well and these Xeons have a 150w TDP
The reason there is no quick sync on SB-E is because they don't have the integrated graphics processor like SB, the IGP is used for quick sync.
I'm not sure about the IB-E news about them being compatible with X79 and the 2011 socket. They probably will be but i'm betting IB-E will have a new chipset when it's released, so even though they might be compatible with the X79 chipset and 2011 socket it will probably just be better to wait for the new chipset for IB-E. It's the same with the desktop Ivy Bridge CPUs as well, they are compatible with P67 and Z68 (gen 3 motherbaoards anyway) but Intel are releasing new motherboards with a new Z77 chipset when Ivy Bridge is released.

CSS Valid
We've been waiting patiently and now LGA2011 is finally here, so we'll take a look at the range topping Core i7-3960X.
