fsb or total Mhz

mjmnam · 10-16-03, 02:23 PM

does F@H need a lot of ram bandwidth? because i was thinking of unlocking the higher mults on my processor, but i'd have to return to the stock 166FSB. i read that you can get the barton 2800 to 2.5Ghz (166x15) stable on air. should i keep my current setup (in sig) or unlock and push it to 2.5?

It's my understanding that total Mhz is the way to go. Don't quote me on it though because I'm quite stupid in the ways of F@H =p.

I'd also go for total mhz, but don't neglect FSB either. It's usally better for components to use a slightly lower fsb, espeically if the ratios work out so you get more mhz like that with the next higher multi.

mjmnam · 10-16-03, 02:28 PM

so you guys thinki should just unlock and go to 2.5?

Deathknight · 10-16-03, 02:29 PM

Why would you need to return to 166fsb? Sure you may need to tweak fsb a little bit when you reach your max overclock but if you think there is going on another 300mhz left in your chip you should be able to bump the mult and still have your high fsb.

the problem becomes heat and power consumption. my psu isn't strong enough for me to sustain 196x12 @1.8. the 5V rail dips too low and eventually the computer will just reboot.

there was an article at Tomshardware that showed how to unlock my processor and said that they could get it stable at 166x15 but not completely stable at 200x12.5

besides at my current set up, the 5v rail drops to 4.84 at 100% load. oddly it's the only rail that's weak.

Deathknight,
what are you using to cool rig1?

Deathknight · 10-16-03, 04:56 PM

Using Prometia to cool rig 1.

The reason rail5 is dipping on you is that the A7N8X uses the 5v rail to power the CPU. If you are having stability issues at 196x12 @1.8 then I would imagine you will have stability issues with a higher mult and lower fsb as well. Regardless I don't see you getting another 300 mhz out of a machine that is already having power issues. Best of luck with it though, hopefully you can squeeze out more

well, i thought it didnt matter if it was a multi vs fsb thing. Becuase you can have high multi normal fsb and 2.4Ghz yet you can still get that 2.4 Ghz with a lower multi and a high fsb.

but their may be complications that your PSU and/or cpu/ram might cause.

Good question though! i wonder if F@H benefits from high fsb. i assume no becuase i hear AMD folds faster than intels in general, so that must meen its pure processing power. becuase AMD has alot of processing power and intel has high mem bandwidth. So i assume its the processing power that helps fold

aka Ghz and work per cycle

Arkaine23 · 10-16-03, 05:12 PM

FSB helps by a very small margin.

As for the A7N8X- the 5v usually reads lower than actual in the bios. And that board also overvolts the CPU by .07v.... Not all CPU's react well to lots of voltage, no matter how cold you make them.

mjmnam · 10-17-03, 06:01 PM

well, i can get it to 196x12 @ 1.8v stable, but the diode temp sits around 55 or 56 at full load (case temp 20c on Zalman CNPS7000a-cu)
