TPU's Core i7 Overclocking and Feedback

[n-ster]

Do you want maximum OC? or do you want to stay at 4ghz? because if you do stay at 4ghz, and the BR does the same job as the DFI, then you can satisfy your need for a nice looking board without sacrificing performance!

 

[Chicken Patty]

I say DFI, DFI still looks bad ass

 

[n-ster]

Well, you got to agree DFI isn't that pretty... but everything is forgotten when you see it's OCing capabilities

I think DFI's look great But the bloodrage is very sexy indeed.

 

[SystemViper]

I have to say Bloodrage, but I don't like DFI at all, the last board i liked that they made was the marzzzz. But i am very biased when it comes to DFi

Well, I normally love DFI, but I've had to RMA 3 DFI boards in the last year, and I've heard great things about the Blood Rage, and for the couple of days I had it...I'd have to say it was the best looking board I'd ever seen.

 

[Binge]

That was a great score you had with the 920 SV, and I'm sure you'll have a whole new experience with the 965.

Let me recap, maybe you understand this way . It took my a while to understand as well. I printed that article out at work and read it a million times, I even took it with me whenever I had to take a shit! But hey hardwork paid off. I got the hang of it


The uncore multiplier has to be twice as much as your memory divider.

Default uncore on most systems I think is 16x. So if your uncore is 16x you need to run your ram divider at 2:8.

So here is how you find your values


Uncore 16x multiplied by your Base Clock (FSB)

Example: 200x16 = 3200 MHz uncore speed



QPI multiplier is locked on the i7 920's at 18x.

Example: 200x18 = 3600 MHz

The general rule of thumb is you want to keep your uncore lower than your QPI. But your uncore needs to be twice as much as your memory divider.

The most ideal way of doing this is keeping your memory divider at 2:8 and your uncore at 16x. This way you stay at that 8:9 ratio for the uncore:QPI that kid was talking about.




However thanks to Giorgos, I have decided to expirement running my uncore higher than my QPI and so far no problems.

I am running my Uncore at 20x and my ram divider at 2:10. Notice that RAM divider is exactly 1/2 of my Uncore.

Here is a screenshot of my settings now. I am at a low clock as I am testing how high I can bring the memory up with a divider of 2:10.

BTW mudkip, if by any chance you have stability issues when you start getting close to 200 BCLK, dropping your RAM divider will give you lot of stability. Either that or crank up the voltages, but that depends on how you use your rig. this is my 24/7 rig, so I try to stay conservative.

THat screenshot above is my rig crunching, its been crunching for about two days now at these settings, idle voltage is 1.107v, load as you see above is 1.141v.

Ok thank you guys.. so how higher the FSB: DRAM ratio how more chance for unstability.

Good to know

For anyone looking for a good x58 board, I'm going to sell the DFI and keep the Blood Rage. If anyone is interested in the DFI board send me a PM. As stated in my sig, I'm looking for $197 or a straight up trade for a good 22"+ monitor or a gtx260. The DFI bios was updated by DFI before they sent the new board out.

That info should be on the first page of this thread, dark's posts.

Fits, Paul help me out here

Lol.

Anyway,

Core i7 920 at 3.8GHz is 100% do-able on air, I already did that with my Cooler Master Z600R. And with Hyper Threading disable, I able to reach 196x21=4116MHz on air.

Of course, I already tested them with prime for over 7-12 hours, you can see my results in this threads if you were reading it since the start.

Did you compare the results between the Core i7 and the Core 2 quad?

I think they are should be similar when you compare core i7 to Phenom II.

When I still have my 8800GT SLI, games performance are alot faster in XP and Windows 7, at first I thought it was because the thread management of Windows Vista. But, it's not 100% because of it.

When I bought this GTX280, and I did some tests on Windows Vista, XP, and Windows 7, I did not notice any real different in performance.
I re-benched my last 8800GT (single card), and I did not notice any different too.

And from what Binge said, he did not notice any different in his benchmarks, and he had a single GTX280.

What I'm trying to say is,

In multi-gpus setup, the results appear to be better in Windows XP, and Se7en, maybe because in Windows Vista, the second gpu uses the virtual core instead of the true core, this is just my theory, but it's proven in my case.

3.8-4.2GHZ for after market cooler air or all in one water 24/7 .... more for nice water cooling ...and more yet for Peltier and the likes....These CPU's run hot but they also run very well hot....but no one likes heat.2.66-3.8GHZ for stock cooling ....

 

[niko084]

I'm sorta nailed to a budget here, or so I want to be nailed to one..

What's the opinion on the Asus P6T?
Also http://www.newegg.com/Product/Product.aspx?Item=N82E16820231247

Considering that with a Xig. Black Knight S1283 for cooling.
I should be able to run 3800-4000 pretty easily you figure?
Sorry i7 920.

it takes me to 4.5GHZ with out a hicup.....

Good deal, what about the ram, I hear a lot of horror stories about ram and i7's....
Maybe it's people not knowing what they are doing?

 

[PaulieG]

It appears a overclocked phenom II is faster by a bit in that test, over a stock I7 920. That's seems to make this a bit harder and less clear. I was shocked to see how close they are sometimes. Some reviews show a overclocked I7 up to 75 percent faster but most don't show those results, its hard to get a clear handle on this data. Some reviews I have seen show a phenomII beating a I7 in games , but I'm not sure that's true either. Also whats a true expected I7 920, on air, overclock for 24/7. Not a bench but a true speed used for every day.

Fits, Paul help me out here

Tom, I've owned both setups. In terms of gaming, the PII can hang in with the i7 when the PII is overclocked significantly. However, once you start overclocking the i7 up over 3.6ghz, it's really no contest. Not to mention benching (which is a something you enjoy), the i7 is in a whole different ballpark. trt, you have PM.

how hots are your voltage reg and northbridge, they got a bad rap on your board?

here is the system I'm looking at now

Not sure about that ram ...The feel I have with my rig is very tolerant to ram..

NB and voltage regs are okay ...no real heat issues of any kind other than the i7's run hot...I like the board.

I just got this phenom II stable at 12.5x300FSB=3.750ghz, northbridge 2100mhz and ht link 2100mghz and it screams. The I7 must be a monster because this is fast.

The i7 is truely a beast ...and no issues with 4+GHZ with a little wit. nice clock by the way.

It is a monster. It is just crazy. I wouldn't lie to you man. Oh, and there are people who can get 3.7 on stock voltage with the i7 920.

 

[trt740]

Thx fellas gonna think on it a bit, whats making this hard is this phenom II is very quick and this MSI motherboard is very good. Both were very cheap and I mean cheap.

benchmarks aint everything.


I ran mine at default the other day and scored 5017 points in the CPU test.
