nForce2 benchmarks

[Hundasport]

What you guys think of these?

PCMark2002: cpu=6243, memory 5302

Sandra 2003 Memory bandwidth: 3055 integer, 2847 float
Max mem bandwidth is 3216mb/s

Sandra 2003 CPU Multimedia Benchmark: 11069 integer, 11819 floating

Sandra 2003 Arithmatic: 7503 ALU, 3033 FPU

3dmark 2001 score sucs..., my vid card is old. I get only 3650 pts. If I drop 100mhz, i loose about 25-40 pts...so it's the vid card that's the bottle neck I think.

I am quite impressed, compared to my Soyo KT266A, but i don't like the 200mhz max on the chaintech...I think corsair can do more, but I have the % more feature, which i haven't played around yet. like set memory %120 more, up to %200. CPU temps range from 48-50C. Everything running stable so far.

Are those .13 micron AthlonXP 1800+ the revA or B cores? Also how good are those Cheiftec power supplies?

Good system other than the graphics card. Drop in a nice Radeon 9500 Pro and you are good to go. Those are pretty good memory scores though (beats the hell out of mine).

That is a lot of voltage for a .13 micron CPU (must be teh revision A or you would have made it much higher).

Yeah, thats a LOT of voltage... but what are the defaults on those chips? 1.6v? 1.65v? If they are 1.65v, 1.9v is only a 15% increase.. That said these Intel P4 chips don't seem to like anything over 1.7v for an extended period of time...

Those are very nice memory throughput scores... getting close to P4 bandwidth (except the FPU performance). Why does FPU RAM performance suck so badly on Athlons? I thought they had strong FPUs?

That extra bandwidth sure increases those multimedia benchmark scores though... jeez!

You're better off keeping the fsb/ram at a 1:1 ratio. Setting the ram asynchronously to the fsb will only lower performance.

Chieftec case looks and feels like quailty work. Power supply has plenty of power jacks...450 is plenty...On my old system, i had to do some splicing on my Codegen 9001 ps.

I believe i saw that this cpu was an A versison.

My voltage is now at 1.85v and running good so far. I will drop a bit more in days and weeks to come.

What has other people received in pcmark2002 scores with the kt400's and nForce2's?

Looks like i am nearing my max...i couldn't pass 2ghz yet...what other things can i do now....prob better cooling right?

That is likely the limit on the core. You are actually pretty lucky to hit 2Ghz. The revB cores can usually hit 2.3Ghz or more. They should hit the channels after a while. I'm looking forward to getting something like the AthlonXP2600+ on a 333Mhz bus with an nForce2 board, but it might be a while still (tax returns). A Barton core would be nice if I could afford it. Hammer looks to be out of the queastion as it will only launch at 1.4 and 1.6Ghz, but it will rise quickly to 1.8, 2.0, 2.2, 2.4 and 2.6 by the end of the year. They are setting the P4 rating for double the Mhz. This means they will have a 2800+ and 3200+ at launch. I really think they should just drop the PR rating. Think about it. They said the Athlon was about 25% more efficiant than the P4 and the Hammer was 20-30% more efficiant than the Athlon. That means the 1.6Ghz Athlon64 is really a PR2600+, not a 3200+, unless it beat even their own expectations by a hugh margin. Likely they are pulling these numbers out of their butts. The 2Ghz versions and faster will compete better, but these 1.4 through 1.8Ghz models will not be worth it (except maybe a quad proccessor set-up).
