Sorry for those results. It was incorrect, I forgot to close some programms from tray, when I was testing 3200Uncore.
These results are correct. Only uncore changed (3200 QPI1.41V; 4000 QPI1.59V) and no more.
Uncore 3200 CPU Vantage score 25943

Uncore 4000 CPU Vantage score 26000

Thanks to mastrdrver.

lol, I just stumbled across it because I noticed I had 2 screen shots of the very similar speeds right around 3800. One was 21x180 the other 19x200. I have been running vantage a lot to verify stability after running some prime95/occt/linX. Would run Vantage after running them a few minutes so I could put a decent game load on the system. With my Q9400, I could spend a 45 minutes stressing and things look ok then once I got into a game it would crash after about an hour. Plus, the CPU tests in both Vantage and 3d 06 will quickly show if your system has any stability to it that wasn't seen. One of the screens I had CPU tweaker open to show all timings and multipliers but the other didn't. Made it even worse is that the one with tweaker didn't have the Asus V window open but the other did. I had other shots of Vantage runs at other speeds and was really having a hard time nailing down uncore speeds I was at. I was looking at the Vantage runs too and noticed that first cpu test I thought that score was following uncore. After spending a few more minutes looking at pics, I realized it was qpi.

The other night I finally got 21x195 stable with decent volts. I ended up running the same speeds twice. The second run I ran uncore higher and tighten the first 3 memory timings 1 clock tighter. RTL was also 10 clocks looser on the faster uncore speed. My cpu score changed 250 points for ~380mhz jump in uncore and .25 vvt increase and would probably still need more.

I'm just now realizing somethings about QPI and why it maybe doing in Vantage what it is.

I've always thought qpi was only for the x58. Problem with that is according to Rivatuner in more than one recording, my gpu usage on both cpu tests is 0. After just now initially reading the intro white paper, I believe QPI to be more of a "ringbus" if you will. Basically, it appears to be what the core, memory controller, maybe L3, memory, and x58 talk to each other on. It is also what appears to be what, on Asus boards, is call cpu differential voltage. This is not the PLL voltage, but the signal voltage for the QPI. To put it even plainer, like how all Intel systems talked to each other over the FSB and we tweaked GTL so now all systems talk to each other over QPI and tweaking may revolve around the diff voltage, as listed on Asus boards, or ioh/ich of which I'm not sure yet.

There is someone over in the XS P6t Deluxe thread that mentioned that he was using LinX to stabilize the entire system overclock using the qpi voltage. He had a very small window (.0125v) that he would get ~46 gflops if he was in the window and drop off to, what he called, "weird" 40 gflop results if outside. If QPI is replacing FSB, this would make total sense.

I've got to do more reading this evening as I've been up waaaaaaaay too late. If you got some time to might want to play with it as I'm going to try and do that tomorrow.

If you want to waste some time start here: http://www.intel.com/technology/quickpath/index.htm?iid=support

Watch the video and then start reading. They spend so much time comparing FSB and QPI in the video and white paper I can't help but believe that we are going to be chasing down QPI stability like we did FSB using GTL volt. This time though, it should be a lot, lot more forgiving and easier to tune.

DRAM Settings 1600MHz 8*8*8*24 1.66V in BIOS (BIOS hardware monitor shows 1.648V).
My DRAM is not overclocked at all, because i have choise between 2000MHz and nominal1600MHz. I did not see any difference in "real programms" between DRAM2000 10*10*10*31 and 1600 8*8*8*24, indeed. CPU overclocking is most effective.

+1 you're correct. Some 20+ pages ago I showed that cas 8 2000MHz performs very similarly to cas 6 1600MHz. The Tri-Channel bandwidth makes up for the speed, so latency is really the only issue at a certain point.

[Jakethesnake011]

Some results with my new card. I am liking the gtx 295 with the i7 a very nice setup.

I am going to see if pumping my Uncore over 4000mhz will increase my gpu score, give me some more bandwidth through the pci-e connection. Maybe bump up my score 100 points or so, I say from JJ it did not do much at all to CPU but I think the big impact if any would be on GPU score.

EVGA classified 759 de-mythed:

myth 1: classified 759 is a limited edition
truth... yes but more classifieds where made than asus p6t6 and p6t7 boards yet all the asus boards are readily available unlike the classified 759s. evga and some distributors are holding on to the remaining 759s to keep the price up way higher than it should be. 1000 759s where made(so far) while 800 p6t6 and p6t7 board where made.

myth 2: classified 759 is the best OCer of all the x58s
nope, other boards such as the DFI UT and asus rampage II extreme as well as the gigabyte x58s have all clocked just as well as the evga 759.

myth 3: the nf200 chip taxes performance
nope, the nf200 allows full use of multiple 16x slots all running at 16x instead of stepping them down to 8x in certain configurations. the VERY small amount of delay that the nf200 causes is not felt because more pcie lanes make up for it. and yes, the nf200 DOES make high end cards in SLI setups perform better. 8x will bottleneck a gtx295.

myth 4: the classified 759 is the most durable and best designed x58 out
nope, shamino(the great OCer/engineer that designed the classified) even admits to PCI-e voltage overload problems with cards that draw excessive amounts of power through the PCI-e slots causing premature failure often resulting in fried mobos. more info here... http://www.xtremesystems.org/forums/showthread.php?t=226942

sorry if i made anyone mad. im just tired of ppl telling me the damn classified is SOOOOO great.

its no better than the other great boards

Yeah. I'd say there is 3-4 GREAT x58 boards from what I've experienced. The Classified is the only supposedly great x58 board that I haven't tried. There is no way that it's any/much better than the UD5. It certainly does NOT deserve to be $100 more.

 

[Fitseries3]

no board has anything on GBs 2oz copper designs

So true. Do you realize that regardless of dozens of bad overclock attempts over the last 3 months, I've never had to clear the cmos manually or pull the battery? The damn thing always fixes itself. most stable board ever, IMHO. That says a lot, considering I've owned 50+ boards over the last 5 years.

 

[Fitseries3]

yup... same here.

i actually cant believe i can get this board to run my d0 at 4.6ghz with 1.38v HT ENABLED and still bench! NO other board i've had could do that.

bios is amazing too, all the right features/settings needed for OCing.

Well I know you hated my board when it first came out but after 14 bios revisions none of the x58 boards has anything over a Rampage II Extreme. Also if you want every option known to man plus stellar packaging nothing beats it. Do you need cool lights all over the board, individual led controls, contact connection points for a voltage meter, a water block ready north bridge etc, but if you want it this board rocks and overclocks just as well as the next best board I have owned of 6 1366 boards( DFI UT) but doesn't fail as often.

Asus's ROG series motherboards have an unparalleled reputation within the overclocking community and their Rampage II Extreme motherboard is the next step. Based on Intel's X58 Express and ICH10R chipsets, this ATX board is ready to host the newest LGA1366 Core i7 processors for ultimate powerful performance.

Up to 12GB of DDR3 1333 RAM can be installed in triple channel mode providing increased performance. Get even more performance – up to 1800Mhz – through overclocking. Three PCI-Express 2.0 x16 cards can be mounted for cutting-edge graphic power with support for either NVIDIA SLI or ATI CrossFireX. 100% all high-quality conductive polymer capacitors give longer life and higher energy efficiency by supplying power to vital components independently.

Get eight channels of HD sound from the ADI AD2000B audio chipset for pure, clear audio. Connect up to six SATA drives at 3Gb/s for high-speed data transfers as well as the option for multiple RAID configurations. Integrated dual Gigabit Ethernet LAN allows bottleneck-free connections to other network devices at broadband speeds and six USB 2.0 ports allows for nearly unlimited possibilities in connecting peripheral devices.

Yeah. I'm STABLE at 4.5 1.36v HT enabled...

 

[Fitseries3]

there has only been 4 bios revisions since my last tinkering with the RIIE so im not that far off. that board has way too many gimmicks and options that wont be used by most ppl. its over the top and has a price to match. i have nothing against you and im glad to hear you are happy with it but my opinion still stands.

 

[trt740]

now thats impressive, I would love to try to match it but my board so stable I would have to do at least a hour of reading to relearn how to tweak it and overclock it again because I haven't tried in so long.

 

[Fitseries3]

its all in the vtt from my experience.

I'm not sure how you can stand by that statment, and we are now up to 1406 bios and according to ASUS there have been 6 bios updates this year alone , 12 total ( I said 14 thats wrong) So It's been atleast 6 bios updates Fits. A lot can change in 6 bios updates. As for too many bells and whistles, there you might have a point, but for some people enough is never enough.

 

[Fitseries3]

just because i haven't owned one in 7 months doesnt mean i have used one.

my comments where on options and features only. never mentioned bios

You mention all kinds of problems when you first got that board and all of them were true, from bad overclocking, buggy bios and picky ram trouble but they are fixed now. I for one have always like Gigabyte as a standard motherboard but found their bios lacking, DFI, Asus, Biostar always seem to have more options for some reason. However, things could have changed since I last used a Gigabyte board. Maybe it's time to give them a try again.
