Stuck at 2.7 on my Quad

Markatomic · 25 Jun 2007 at 23:01

Stable at 2.7 with the rig in sig. Soon as I put it to 2.8 it wont boot into windows.

Increases in vcore voltage dont seem to make any difference and in fact show as 1.39 in everest, cpuz etc when set to 1.4+ in the bios.
Furthermore there are several settings in the bios that I'm not 100% sure of.
Screenies provided. Any suggestions highly welcomed.

Also wondering what the vtt voltage does/is.
Thanks
Mark

Could be wrong, but I don't think the Striker was a particularly great board for FSB overclocking quads.

Hmm I have heard this... nothing more I can drag out of it!

As I have already said, the 680i boards don't like overclocking with quads. If want to overclock a quad in a 680i you really need an extreme edition with unlocked multi's.

The newer EVGA 680i board is the one to clock the Quads in.

Would I be better off with a P35 board over the EVGA 680i to overclock the quad?
Thanks

Probably, do you have the latest BIOS for your striker?

Well im already at 3Ghz on stock volts. Still only 21C idle.

What cooler are you using and what temps do you get under load?

robj20 · 26 Jun 2007 at 10:08

water and not really checked load temps yet, just went from 2.9 to 3 this morning before i came to work will stick orthos on tonight and check.

No I dont, I'll probably flash it tonight but I dont hold out a lot of hope.
Do you tink any of the bios setting make any difference as screened above?

You are on a P35 board he is on a 680i.

And what is your room ambiant? 21c is very low even for idle with speedstep enabled (im assuming)

Hi Markotomic,

The CPU VTT Voltage option may make a difference to your overclock attempts. From what I can gather it is supposed to stabilize the overclock without adding any more volts to the VCore.It is also supposed to be quite affective when trying to stabilize a quad core overclock.

Worth a try.

This is a quote from the Asus P5N32-E Overclocking Guide at overclock.net

"CPU VTT is the most important setting for stable overclocks. The CPU VTT Voltage sets the CPU termination voltage, allowing for a 1.55V maximum. Using this voltage in combination with the CPU VCore voltage setting can greatly enhance the system stability while overclocked. The system memory reference voltage is split between settings, the controller reference voltage and one option each for the two memory channels. In all cases, the base reference voltage can be set to a maximum of .03V over half of the set memory voltage. (Taken from HardOCP)
"In summary, the CPU VTT controls the CPU termination voltage. Based on Kirmie's observations, it reduces the number of false electrical signals by providing a form of "ground" to pull out these false currents. ." (Credit to Kirmie for the find) My experience with this board is that the max setting (1.55) provides the best results. I have not had a single crash or temperature variation as a result."

Speedstep is off. Im just trying to show that the P35 are an excellent choice for overclocking quads.
