NB strap what is it?

SS-89 · 17 Jul 2008 at 09:33

Could somebody explain what NB strap is? would it effect my OC as it's at auto atm.

Currently running my [email protected] x8 multi 1.32v in bios (1.29 in windows) with memory @950mhz 5-5-5-15.

NB Voltage is set to auto and memory is at 2.15v.

Thanks

Take it you've noticed the Asus tends to overvolt RAM by about 0.1 then?! That got me for a while.

NB on these boards also tends to put more through than is needed. I had trouble with temps as auto volt setting was ramming 1.55 volts through the NB and it was getting kinda toasty. Drop it down incrementally, usually if it boots it'll be Prime stable (same thing for FSB volts, take it off auto and drop it down till it boots). If you add more RAM, you'll need to increase NB voltage.

I know I haven't answered any of your questions but hey I just felt like sharing

Good tip though , these boards do overvolt

Same with the p5q p45 boards. The lowest manual voltage is the same as auto and overvolts to much. Had to give the chipset voltages +0.02v and drop my ddr voltage from 2.1-2.02 to get a true 2.1.

cheers for the tips, booted into windows at 4.0 nowhere near stable though as I couldn't even complete one run of 3d mark (use it before prime to test game stability), it didnt freeze it just ctd'd at the end, normal windows duties seemed fine but not stable for anything else.

500x8

400mhz nb fsb strap

1.4 nb voltage

1.4v in bios 1.36 in windows.

Transaction booster enabled.

5-5-5-15-2t@1000.

That's all I managed to try on my lunch break, would turning off the transaction booster help? also maybe up the volts? it was hitting 62 degrees load on one of the cores, is that too hot?

Transaction booster can be a hoor. Set the Relax Level to 1 or 2, then up it from there until it won't boot. On my Maximus Formula however if it booted into Windows on a certain Transaction boost/relax setting it was pretty much stable for whatever.

Set the Clock Twister to Low as well, once you have it semi-stable play around with it.

You have 4gb of RAM, so maybe 1.5V on the NB but watch the temps with AsusProbe. The NB can hit up to 80 Celsius 'safely' though, have you any cooling on it?

Think I may try 1.42v (accounting for vdoop prob around 1.38) and see if it's stable.

btw measuring temps with coretemp which I've heard is actually 10degrees more than the actual temp.
