over here in oz a number of people are having considerable success with the XP2000+ AGOIA "Y"

in excess of 1900Mhz in some cases.

see here.

Couldn't read as guest and couldn't be bothered to jump through the 8 thousand registration hoops. Fancy a little cut'n'paste for us?

cut and paste yes
fancy no
lots of extra stuff ive missed out, but u can see the general gist of things.
===========================
Well as I mentioned in this post the new AGOIA batch codes OC well..

Karma has a 2000+ AGOIA "Y" @ 1970 default volatge, stable with all PCI devices
on board

My 2000+ AGOIA "Y" is @ 2000 with 1.98V, AGP card and Intel Nic only.

as I mentioned in the other post I picked up a 1600+ AGOIA "4" 06/02. Well its a
screamer

Due to the high FSB Ram timings are slow and CPU decode is normal. But it gives a
good indication of what this chip should do once unlocked with some voltage..

It is not stable atm, above 1900 crashes to desktop in 3D Mark (Drago) and Prime
fails straight away. Windows random reboots at 1940..
lots more to come from this chip I think

Cheers,
Mal

got awhile to go Mal

Forgot to mention, i can run PCmark2002, and 3dmark 2001 SE no problems at this
speed.

Temperature is also only 9C.

It makes you wonder if AMD is making any other tweaks to the core. Doesn't it seem peculiar that the PR ratings are still conservative and they more than match comparable P4s?

Well, as a worker in the yield enhancement group of fujitsu, I can tell you a possible reason for the new higher speed cpu.


The less product you run in a process, the higher your yield, there are many reasons for this, the main one is cleaner tools.(less inpurities are introduced because of less lots ran).

Since amd is making .13 micron tbreds etc, their .18 line will be at less than capacity, therefore cleaner, thusly the yields will go up, resulting in exceptional overclocking cpus.


Thats one possible reason for it.

What about performance? What makes the Athlon XP 2100+ match the P4 2.2GHz? Why is the PR rating working when it's not linear?

I'm guessing that the AXP simply does more per clock.
However the benchs for the 533FSB NW and PC1066RDRAM show threat. However they do bring up the PR rating's relativity to P4s, so it still would not be of any trouble until PR per P4 clock is not as performing. Which means that even if the PR2500 is not what a Tbird 2.5GHZ would give, or maybe it does, until a 2.5GHZ P4 outruns the 2500 completly, the PR is not useless and is competing.
However AMD has got to use 200 pts steps from now on, because the new NWs have much room for MHZ and already are equipped with even higher bandwidth and better IPC.
I expect AMD to get to PR2600 by June hopefully, or summer.
One thing, they must NOT disregard DDR400 and 400MHZ FSB at all.
<A HREF="http://www.x86-secret.com/popups/articleswindow.php?id=41" target="_new">http://www.x86-secret.com/popups/articleswindow.php?id=41</A> This shows how AMD can benefit to over 40% in IPC increase and can compete even further, plus better clockspeeds with the new BUS, or vice-versa, low clocks, high bus, allowing even more headroom and extreme comeptition to P4's bandwidth.

What? I dont follow.


The 2.2ghz p4 is neck and neck but probably extremely slightly faster than the 2100+. Pr rating is linear with itself.

Thats because performance is not linear to the % increase in cpu speed alone.


66mhz=100pr, the increase is linear to itself. The % difference between 1.33>1.4ghz is not the % performance improvement from said increase.

Yep, hence the ex employee.

(in my bio)


Fujitsu gmd closed, not the whole company though.

But I assure you, thats one possible reason why we are seeing new higher yield axps.

So if I wanted to buy on of these overclockable cpu,
what do i need to look for so that i know its the right one???????
