FX55 + A8V + vcore Question...

My BIOS is set to 'Auto' but Asus Probe reads my vcore floating around 1.47-1.486 (occasionally dipping down to 1.45ish). I've got a slight oc @ 206 mhz and an Enermax Noisetaker 600w psu.

Isn't this too vcore low? Could this be causing some of the BSOD's I've been getting in WoW?

What can I safely bump this to on air w/a Zalman 7000Cu? My cpu idles @ 40 C and the mobo @ 30 C.

Thanks for the help and advice?

1.6 is safe, provided temps stay reasonable. FWIW, I'm not able to set the vcore on my board between 1.475 and 1.575. The BIOS allows me to, but voltage stays at 1.45 until I hit 1.575 at which point it stays there.

So when I try to manually change the setting in my BIOS, it requires me to manually set my multiplier too. What should this be set at? I'm not looking to do any serious oc'ing...but I'm not sure where it should start.

thx

well, base multi on a fx-55 is 13x, so unless you want to take your ram up real high, just leave it there. Try bumping vcore to 1.6, and, say 220 on the fsb, should be a good start...

thx L3p

What about the AGP/PCI frequency settings? What the heck are these are where should they be set?

66.66/33.33 or 75.4/37.7?

thx

66//33... yes. also, a64s like high multiplyers, so you may as well make use of the FX unlocked multi.. try 14x200 at 1.6 or 1.65v. just play around :>

This is interesting....

With my vcore set to 1.60:
ASUS PC Probe reports vcore around 1.51-1.53ish
CPU-Z reports vcore @ 1.56-1.60

Which do I trust?

That's good advice, but I'll add mine.

For some reason, voltage readings on the Asus A8V are low, but it's no problem.
The default when the Vcore is set to Auto is 1.55 and the reading will be a little bit less.
Leave the multiplier where it is at 13 unless you use Clockgen found here.
http://www.cpuid.com/clockgen.php
If you set the multipier to 14, you are raising your FSB by 200 to 2800. The chip will handle it, but you have to watch your temperatures. As you raise your FSB, you need to also raise your Vcore. The side effect to doing this is heat. If you try for a multiplier of 15, you may lock up, and then you'll have to reset your Cmos to get the MB to work again. If you use Clockgen, the settings are not saved, only temporary. I found out about this the hard way.
Run the Asus Probe monitor, and Prime95 at the same time, your cpu will be much more than 40c, more like 50c. Or you can run your game in a window, while watching the Asus Probe monitor.
Raise your FSB to 210 (2730), leave the multiplier at 13, and raise your vcore to 1.6v. Then try running the benchmarks and see if they complete. You raise the FSB until you have problems, then give it a little bit more Vcore. The highest Vcore I've found on my board is 1.725v, above that, it doesn't help.
Some have gone all the way up to 3.0 on air, but their benchmarks lock up. If you want to try for that, you would set your FSB to 230, vcore to 1.7 and then see how hot you get.

Wanna know the easiest way to do this? Let the MB handle it. Go for the 10% over and everything will be set for you.

That will put you at 2860, which is nice. I've found I get my fastest 3dMark05 scores doing this.
Then run the Asus Probe monitor and see how hot your CPU is. If you are at 60c or lower when running Prime95, then you're ok.

Thanks for the advice!

Right now I'm @ 13x, 207 htt, 1.60 vcore, 1.6 AGP

When running 3DMark05 my temp got to 62 C....I'm assuming this is too high?

And what the heck is V-Link voltage? and what do I set it to?

I'd say you could go up to 65c as the highest, but I wouldn't go above that.

Not sure what V-Link voltage is, I've never messed with it. The only settings I mess with is DDR Votage set to 2.8, Vcore between 1.55 and 1.725 depending on how high I OC, and the FSB speed.

Go back and let the MB do it for you. Try 5% (210 FSB) over and see how hot the CPU gets. Then go 7% over and watch your temps.

Your next project will be to get a Koolance Exos AL water kit and your temps won't go above 50c.
You can buy the parts on Newegg, it's easy to install, and works.

And then you need a special clip from Koolance.
