Overclocked Athlon FX?
Was just reading tom's hardware guide:
Almost all benchmarks underline the fact that the nVentiv (formerly Chip-con) compressor cooler enables the AMD Athlon 64 FX to scale up beautifully as clock speed increases. In our case, the clock speed of the Athlon 64 FX-51 was increased from 2200 MHz to 2800 MHz, without the speeds of the memory, FSB and AGP being affected. A special BIOS from Asus (SK8N) allowed us the multiplier to be adjusted (increased from 11 to 14). The average performance increase of 27 per cent almost exactly matches the clocking increase of 27.3 per cent, particularly in the case of the professional 3-D rendering applications (for example, Lightwave, 3D Studio Max and Cinema 4D XL). But the Athlon 64 FX also makes considerable performance gains in video encoding (MPEG-2, MPEG-4) and classic office applications, where we saw a similar correspondence in scalability.
The Athlon 64 FX (Opteron) architecture offers ideal scalability with respect to clock speed - much better than that of the Intel P4, for example. Compared to our previous test environment - as described in AMD's Athlon 64 Has Arrived: the Athlon 64 FX and Athlon 64 (and Intel's P4 Extreme) Reviewed, there is an average increase of 3.5 per cent in memory performance of the system based on the Asus SK8N.
The cooler system had no trouble keeping the CPU die temperature down to a steady, low range between -17°C and -22°C (signal evaluation of the thermal diode).
What's wild is that the system uses an AC compressor!

Reading that site always makes me want to spend money.
Have you stepped up to the pump on 64bit yet or are you still with your
nforce2?
I think I'll hold on to my nf2 for the moment. Spent some money on a SATA
HD and maybe put my GF3 ti200 out to pasture.
The video card hing worries me because even the new top end cards
from ati and NV don't seem all that smoking in the DX9 benchmarks yet.
Might have to wait.

Here's a benchmark:
I'm still on nf2 myself.
I've got a AHA2940UW card staring me in the face right now, and have access to almost 30 9GB drives...Very temping to go to town and build a GREAT game box...

mmmmmmmmmmmmm Raid.
Haven't had a SCSI setup since my 486DX33 with TWO!!!!-540MB HD
And a bitchn Matrox millenium card with 2MB ram.

Old time memories.
That and bringing my computer to school so I didn't have to use
the schools 8088's to try and run Autocad R10.

cop: "is that a 2000?!?"
more on topic tho, i'v never understood why performance wouldnt increase linearly with clock speed. if it were like networking where collisions and lost packets became an issue, then i'd understand, but i assume if u get thsoe kinda effects frmoa rpocessor, u'r screwed.

Freek,
I'd imagine that the benchmarks for measuring oc'ing do not soley rest
upon CPU task, but a ombination of components that are involved.
If you simply increase the amount of processor speed. The information still has to work it's way throught the system.
Like friction losses in a motor. You can run a lighter oil with a lower
coefficient of friction that is 100% less resistant. But this increase of 100%
only affect the 20% of power lost due to friction.
Thats my take.

i'm not sure i entirely buy that concept cause as i know processors (and that's not saying much) it's a much more absolute thing. but it is an interesting theory and may very well proove to be right. i also wonder, if they didnt increase the clock speed of the memory, how did they get linear performance increase? shoulda been less. unless it someone ONLY measured processor speed, tho i cant imagine how that would be possible. unless the memory was "faster" than the chip to begin with so it didnt lose any speed in keeping the memory at the original rate. this doesnt make any sense to me either tho. whether it's sync or async memory (dont know what is used these days), it shoudl slow down the chip. unelss the test is all cache, in which case it makes sense.

Dual path DDR400 memory shouldn't be much of a bottleneck.

hey freek, maybe swift is saying that the processor IS actually running linearly (is that a word?) faster, but it's the OTHER COMPONENTS that affect the measurement of that speed increase. ie. memory bus speed and access speed, bus clocking and bandwidth, blah, blah, blah.
You may be right that the memory speed is/was at 200Mhz just like the core clock for the CPU. (then the DDR memory would be 400Mhz actually)
PHINGERSNIFFER: what the heck ya still running a GF200 for?!?!? Get rid of that old crap man!

We should have a benchmark showdown freek. My work machine is a
PII-333 with and 8MB rage pro card. and whopping 64MB ram. It at least keeps me from playing games at work.
BA-
The GF3-ti200 was an upgrade for me earlier this year when my GF256
crapped out. It's not that bad. MSI -126mb tv in and out. Good fan and
heat sinks on the memory. Overclocks nicely. Got it second hand for 75cdn
Just having trouble shelling ot 300cdn for the card I really want. But
don't really need. I need a bigger HD and Win XP first.

lol! kinda like getting grandma and grandpa Bones to enter a strongman contest  hey, at least i got 640M ram. that's the only thing that keeps this puppy from droppin dead under the weight of the heavy development i do using IE under windows!

EBD, you got it. I'll take a 1.1 ghz FSB over 266x2 any day!
You guys overclocking should be running a raid drive setup if you are looking for speed.
Now with redundancy and speed theres no reason not to...

Hey Phinger! I hear ya man. And you're right, it does OC nicely, I used to have one too, but it wasn't the fancy schmancy 128MB Tuner version.

BA- I just lucked out when my GF256 crapped out. I was ready to buck up for a GF4-4600 and my the shop I was getting prices from, just got it in on a trade. Picked it up cheap. The new 5700 Ultra is temping right now though. I notice a bit of lag in wolfenstein et and call of duty with max settings on.
Unfortunatly all my cad and lighting sofware already smokes along ok.
and I can't warrant a quadro card for the little amount of work I'd need it for.
