EVGA X58 TRI SLI Discussion thread

[error10]

I couldn't get the EVGA X58 stable at 200x20. I wound up running it at 200x19. I pushed it as far as 215x19 in E-LEET but wasn't willing to run the voltages necessary to keep that stable.

Well Im at 4.044GHZ @ 1.376v right now so progress is being made.


I used this method:

The Strategy:
Prereq's: p95v25.8, LinX, E-LEET, RealTemp and/or Everest Ultimate are already installed. Adequate cooling for the CPU must also be in place. Overclocking past 3.2Ghz should not be done on stock cooling.

First do a reasonable amount of testing to ensure your machine is stable at stock clocks. No cores should reach 85C under a load.

Once that is complete, launch E-LEET, RealTemp and p95.

Now lets see just how far you can go on STOCK EVERYTHING!

Once in E-LEET, go to the Voltage tab and note all the settings.

One thing to ensure is the CPU VTT and the DIMM Voltage are always within .5v of each other. This means if CPU VTT is 1.1v for example, the DIMM voltage can be no more than 1.6v.

Now go to the Overclocking tab and increase the QPI by 3-5MHz and hit "Apply Selection"

Watch your Core temps in RealTemp and start p95 to stress all cores. Also note your under load Vcore, DIMM and CPU VTT voltages. Keep track of these for use later.

After 5-10 minutes or so if there are no BSODs, lockups or errors and your temps are not over 85C, stop p95.

Repeat the previous 3 steps until your machine crashes or your temps get over 85C. This will happen becuase either you will cross a strap or come to a point where stock voltages are not enough.

Once you crash or have increased the QPI say 10MHz, reboot and enter in the last good testing QPI into the BIOS.

Once back in Windows, go back to the beginning of this procedure and increase the QPI more agin in small steps until you crash again, reach your desired overclock OR the point where AUTO voltages can take you no further. Once at the "max auto voltage point", vcore and CPU VTT will need to be set manually. Where you set vcore will depend on the vdroop setting so "with vdroop" vcore will need to be set to a value of ~.15v ABOVE the load voltage of vcore but ~.1v BELOW it if running "without vdroop".

Depending on QPI, vdroop can either be off or on in the BIOS. If "with vdroop" is set in the BIOS, I use a step size if 2 notches for vcore and 1 notch for VTT however if vdroop is set to "without vdroop" in the BIOS I use a step size of 1 for both vcore and VTT.

I havn't touched any settings other then vcore, VTT and DIMM voltage. And I need to run P95 for a few hours to verify stability.

some i7's have the 20x multi...

for example on my i7 965 I had to up my multi to 21 from 20 to get it stable @ the same voltage and settings! Ummm okay!? faster speed and more stability? PLEASE!

[error10]

Eh? The stock multiplier on the i7 965 is 24.

I've got the same cpu/mobo/ram/water and i've been able to get my bclk to 222, right now I'm using a 19x212 (about 4Ghz) with 1.2625Vcore bios, 1.27Vcore windows. I can take some pictures of my bios if you would like me to. I found that the odd multi 19 helped me keep the voltages down.

Ya, I meant that the only thing other then QPI that I have touched were the things that I mentioned.

I'm using the 20 multi with turbo and I'm up to 1.4v trying to get it stable. Temps are still fine. I'm knocking on 60C running small fft's now.

The 19 multi has me curious. As for the pictures, it would be appreciated because ther is still a whole whack of settings that I havn't fiddled with yet because I don't know what they do.

Ya, there are bound to be some holes.

So using the 19x multi, I seem to be topping out stability wise at 205 QPI. Any higher then that, and my board threw a beeping fit. Literally. That's using 2:8 divider. I tried using 2:6 and the board didn't like that at all.

So what's uncore used for? Any usefullness to this setting?

[Slightly skewed]

Ok here are some temps etc. So far so stable.

[MrMason]

Sorry it took so long, here are some pictures of my BIOS to give you an idea.
