This took me 6 days 24 hours a day to achieve. I did get to 14 hours before I shut it down which is a complete loop and a half for Prime Blend "the program repeats every ten hours".

It wasn't easy to pull this one off but the settings look pretty normal with most everything in the green settings except for FSB. I Only needed 1.368 Vcore for this so temps were well within tolerance.

The GTLVref lanes were very difficult to get right. I even figured out which blend tests relate to the GTLVref lanes. They don't occur until you are 4 hours into Prime blend test so using the custom test to work on the more difficult K numbers really helped. Read down further if you want some info on which tests seemed to relate to GTLVref tuning.

I bet some of you guys might curious what the bios settings are....

Please ask questions here in this thread instead of PMing me guys.

Check out the Memory and latency numbers in the Everest Memory bench mark below. The higher read rates are because of the fast GSkill pc2 9600 which runs at it's it full rated 1200MHz cas 5 speed. The 4:3 divider works out well with this Ram and 1800FSB-QDR using 450FSB X 1.33333 = 600MHz membus X 2 = 1200Mhz
4:3=1.33333

The 4:3 divider is a good one but doesn't show up in bios so there is no auto setting for it in the memory settings. That is where the equation above comes in handy.

Here is the difference at 4275MHz, notice the higher write speeds and L1 cache because of the higher FSB but a slower read,copy and latency compaired to the 4050MHz setting.

Super pi 1M score looks pretty good also. This is at 1920FSB 4320MHz.

And my average Vantage score went up also. If it was only colder I could easily break my old score. This is at 4275MHz with my original relic vanilla 280 which doesn't overclock very well unless it's cold.

The stability is impressive, but I'm more impressed with your patience

I've been reading up on gtlref voltages, but I'm having a hard time conceptualizing it. Math is my weak point, so it's going to take some more studying before I fully grasp it.

Congrats on the overclock!

Honestly Slash, no math was used to find the correct lane values. Patience payed off for me here, in fact I discovered which Prime tests related to the GTLVref lanes which was key to dialing them in. I have a few settings you will want to know about which can make all the difference in getting your Q stable. PM me if you want them.

Congrats! Decent temps too, though intel burn test I find gets around 10C hotter than prime for me.

So what settings in prime is the best test for GTLref?

The 32K and the 320K are the ones that seem to relate to GTLref settings, you need to find a balance between the two. If you can pass both of those tests 5 passes each then your GTLref's are dialed in. They come up at about 4 hours in Prime blend. I use the custom test so I can run those two tests independently. Use the 1600 Mb Ram tested or even a bit more if you want to stress it more. Blend uses 1600Mb Ram by default.

Just getting to 4 hours is an achievment and the other voltages will need to be fairly close to correct for that to happen.

Start at +90MV all 4 lanes and work up and down a bit from there. Lanes 0 and 2 work together and lanes 1 and 3 work together. The other GTLref rules apply but for lanes 1 and 3 you will problem only get freezes to indicate the setting isn't right.

To set up the custom test for 320K you would do this. Notice the 1600mb Ram being tested "very important". Do not check fft's in place.

question chevell, what did you put down under Time to run each FFT size(in minutes)?

and

did you check the box for Run FFT s in-place?

To run the test same as in Blend do not check FFT's in place. Don't put anything for the time. Just input either 320 into each box or 32 into each box and it will run those tests over and over again. 5 passes are needed to be sure. You need to pass both to get your GTRLref's dialed in.

Use the standard 1600Mb Ram tested which is the same as Blend uses. Sometimes I will bump up the Ram tested to 2000 or so just to add some stress to make sure it's stable. A rounding error indicates you need to raise the ref values in the correct lanes.

Rounding Errors in Prime Blend on core 1 and 2 means raise or sometimes lower values on lanes 0 and 2.

Error's on core 3 and 4 means raise or lower values on lanes 1 and 3.

Freezes seems to relate more to lanes 1 and 3 not being correct so adjust them up or down with a max of +110. Wierd stuff happens at +110 so you should not adjust higher than that.

Rounding errors are good because it lets you know which lanes to adjust. Freezes mean you aren't quite there yet but related more to lanes 1 and 3 being off. +90Mv for all lanes should be a good starting point. Being just 5 MV off can make or break your overclock.

To dial in those lanes you need to run five complete passes of each test 32K and 320K to be sure it's stable. Each pass is about 15 minutes. This can save you a lot of time because you can make adjustments to get past those tests without having to wait 4 hours to get there again.

You still need to run Prime Blend long enough to get to those custom tests. If you don't the chip-set voltages may not be right. The 32k and the 320k tests are just sticking points that seem to relate to GT-lane adjustments the most.

That way if you are going for 12 hours you can be assured to pass those sticking points the next time you get there. Prime blend repeats itself after ten hours so there is really no reason to run more than 10 hours.

Remember that Prime names the cores as 1 2 3 4 top to bottom. But the GT-lanes in bios start from 0 1 2 3. In Prime cores 1 and 2 relate to lanes 0 and 2. And core's 3 and 4 relate to lanes 1 and 3. Yes it's confusing as first.

So you would adjust in pairs like this as an example.

+55 lane 0 = < adjust for rounding error on core 1 or 2.
+65 lane 1 = < adjust for freeze or rounding error on core 3 or 4
+55 lane 2 = < adjust for rounding error on core 1 or 2
+65 lane 3 = < adjust for freeze or rounding error on core 3 or 4

The lane adjustments can be up or down, you will get a feel for which way is correct.

I think this is BR worthy, Chevell.

I can't believe the number of people on these forums asking for help with bad quad overclocks, that have all the GTLRefs on auto.

How did you isolate those particular tests? Trial and error, or some research/advice?

This is the kind of method and patience that makes the overclocker. Hats off to you.

What did you end up with on your lanes?

This took 6 days of nearly 24/7 monitoring with endless trial and error combined with many setting changes to confirm relations to certain bios settings. Also, pages of notes and endless hours of running boring tests. The only thing that kept it interesting is discovering that certain bios settings would effect certain tests more than others.

Mostly the first three hours of Prime blend required you to shore up the NB SB and set Vcore fairly accurately. The required MCP setting was most interesting.

After that the 384K at 3 hours 10 minutes seemed to require more Vcore to pass and was good for getting Vcore setting very close to correct.

The 160K test at 6 hours 14 minutes was very stressful and made the most heat during the 10 hour loop of Prime blend. It seemed useful for setting both total Vcore and also seemed to be Ram voltage sensitive requiring exactly .025 more Vdimm to pass consistantly.

The 320K and the 32K tests which occur at 4.5 hours seemed very sensitive to GTLVref settings. Those two tests required a perfect balance between the two lanes or it would give errors or freeze. Just 5mv either way and it would not pass one of those tests.

Using the custom tests in Prime I adjusted the lanes until they could both run each test 5 times to make sure it would pass when I tried for 12 hours again. It took me three days to dial in this setting because I had no idea where to start.

I'm sure everyone's required settings GTLVref lane settings will be different but at least now some of you with 780iFTW Q9650's might have a decent starting point. Starting them all at +90 and working up them up and down a bit from there is a good starting point is seems like. I ended up at +100,+85,+100,+85.

If you seem to get stuck at the 32k and the 320K tests then use the custom test in Prime as described in earlier post and keep running both the 32K and the 320K tests until you can pass both at least five passes appox 15 minutes for each pass. That way when you get there again you can be certain that you will pass.

It was more out of curiosity that I asked about which settings you arrived at. As you say, everyone will have different sweet spots on the lanes. It also changes with the VTT and FSB frequency as these alter the required GTLRef ratio.

I was unable to get much over 4GHz with my Q9650 and 780i FTW. I tuned exhaustively as you have, but never found a completely stable setting.

Since switching to the 790i Ultra, I have been able to get much higher clocks. My Lanes ended up being something like -100, -90, -80, -80. This of course indicates that I would never have been stable on the 780i FTW no matter what, because it doesn't offer negative adjustments.

Anyway, good job. If your method is accurate, I'll never take days to tune these again (if I ever have to).

Interesting that you happen to be at 4320Mhz 1920QDR. That also happens to be where my next good divider is to keep my Ram at 1200Mhz on the nose.

I'm only using 1.368 vcore for 4050Mhz so I figure I have a decent chance at making 4320Mhz. Maybe next week for that one.

One more thing; you should change the title of the post.

More people will read it if you mention a fast track for tuning GTLRefs. It's good info.

Sell it bud.

Tuning those lanes sure wasn't fast for me but the info I picked up might help some others figure out how to tune them faster so I'll adjust the title since those lanes were so important for gaining stablity. Thanks for the input psynapse.

I wish I could get mine up there but it will never happen. Not with the way my CPU eats voltage for breakfast... I had mine at 1.6875 vcore for 1900 stable. I run mine at 1800 daily.

Eating voltage is right.

I need 1.46 in bios for 4320MHz 1920QDR which now easily passes Vantage and gives me good cpu scores. The one I posted is my daily setting and it sure is it snappy with that 1200MHz ram. It was easy to clock up, just another notch up for the chip set and the vcore then a bit more work on the GTLVref's.

I'll put the Everest bench,super pi 1M, and my Vantage score into the first post.

The patience is what got me the proper technique, the beer just made the Endless time more barable.

Luck would have been to guess at the correct settings in the first hour...but six days later I didn't feel so lucky.

Now that I have a stable base to work from I can run 1900FSB 4275MHz 4 hours Prime blend stable which is good enough to run Vantage all day long, and Crysis also it seems.

I really didn't think I could get that far with a Quad on air.

As you can see me and chevell have the same processor and both have the 780 based nvidia mobo (mine's the regular SLI, his is the FTW). The big difference is the vdroop setting in BIOS, but I solved that using the pencil mod.

I ran Prime95 for 12 hours and was stable at 4.05ghz, or so I thought. I have my computer running pretty much so 24/7, and every day or day and a half, I would have a freeze. No BSOD, just everything would freeze up and I'd have to do a hard reboot. I had a feeling it may be a voltage setting, but I really didn't know where to start.

Then, 6 days ago I read this thread. I used the settings chevell recommended, and for 6 days not a single freeze. I ran Prime95 for 24 hours with no problems. What's really cool is that at 4.05ghz, both of our CPU's maxed out at 69c! I know most gurus out there keep preaching that no two systems are alike, and I may be able to tweak my voltages down a little from chevell's and still be stable (I doubt it), but I think this is one of the best examples I've seen of how this community is supposed to work, and how successful it can be.

So for all of you peeps out there that aren't willing to share your settings, here's my two cents. If people are coming to this site, they've got to have a little intelligence. I think that most people that visit this site are smart enough to know that number one you overclock at your own risk and number two that if you use someone else's settings and they don't work or fry your shizzle that you can't blame the person that recommended the settings. Overclock at YOUR own risk puts all of the responsibility in the overclocker's hands. No sensible person would blame another for a screwed up OC. And if you do recommend settings to someone and they blame you for an epic fail, remember, they're just a dumb a$$!! Like they could legally do anything to you anyway...

So the moral of this rant is take time to help those in our community. Point a noob like myself in the right direction and recommend some settings. If you're still paranoid, put in a disclaimer. Be teachers, mentors, masters. Help someone make an epic SUCCESS!

Well said Darth, the overclocking techniques I outlined in this post would work well for anyone I think.

Those freeze ups get to be a real pain I agree. Shoring up the chip set voltages make the freeze ups go away for good. Prime small fft's is only good for getting the Vcore simi close and that's about it. Prime blend is the real test because it stresses the chip set and allows you to get the voltages right on the mark for complete stablity. It's nice to see people who value having a perfectly stable system. It does pay off in the long run.

Major respect from me on this topic. I've been so frustrated with my 780i since I got this Q9550, and this is the reason. I would get an OC that would be awesome, looking like it was perfect and between 4 and 12 hours into Prime it would freeze. EVERY time. I had tried everything that I could think of, even with the GTLs but I couldn't make it work. It seems like everything I read about them contradicts itself and just left me confused. You sure have more patience than I have, because after 2 straight days of working on it I just gave up. I understand what GTLs do and what they are for, but I couldn't make any setting work. After reading this, at least I've got a good starting point and another perspective. So to me, you're the man!

Great thread, i have mine stable the same way for my daily use 4050 ghz with GTLs @ 100|105|100|100.. ( 750i FTW and 8GB Ram )

Chevell i would be interested to see your score on 3DMark06 to see what is your with your GPU.

Thx

What overclock are you striving for? Where are you at now?

I went through the same pain, tuning GTLRef lanes exhaustively on the 780i.

There's a point, and it seems to be around the 1800 QDR area, where it is futile to keep tweaking GTLRefs for a 45nm Quad on the 780i.

Most of them need -ve GTLRef adjustment, so the only way you're pushing harder is on a 790i variant.

My problems disappeared when I switched.

Maybe for you it was futile to adjust those lanes but for me it made all the difference in the world for me at 1800FSB. Did you just miss the point of this entire thread?

Futile would be if I failed but because I was succussful it doesn't seem very futile anymore now does it?

If anything the 790i is much harder to get stable than the 780i, I mean just go there and look at all the freeze up problems...they never seem to end. Few could argue this fact.

So can we end the 790i versus the 780i FTW thing now. That isn't what this thread is about.

There are plenty of 790i's out there that have trouble getting a Quad stable also so it's not really a board specific problem. The problem is that Quads are pain to get stable period no matter which board you have.

Talk is cheap but those screen shots aren't

In fact I have yet to see a single Prime blend stable 12 hour run from anyone here running a quad on either board. So if you have one I'm sure we would all love to see it.

And no, 20 passes of IBT ain't gunna cut it.

I had no problems improving my score in Vantage at 4.32GHz, perfectly stable there in fact. My old 280 and this warm weather is holding my score back is all, Vantage is more about GPU clocks than anything else and I need the cold for that.

I also managed 4 hours of Prime blend at 4275MHz but that 320K test and the heat kills me. Still 4 hours of blend is plenty good for Vantage scores to improve.
