AMD@ 2Ghz vs P4@3.55Ghz: 1-0? - Page 3

RichBa5tard · 24th August 2003, 15:00

true, synthetic benchmarks dedect default speed, but programs like 3dmark do increase in speed.

"some versions of windows"...? i'll install SP1, see if that solves it.

I don't think that will help

RichBa5tard · 24th August 2003, 15:30

It would be pretty odd, if a program released on 18th august 2003 doesn't work well in Win XP...

It doesn't hurt to update, i'll report back in half an hour.

RichBa5tard · 24th August 2003, 15:42

SP1 didn't do it. Installing other updates too.

I'm sure now the incorrect mhz recognition is the cause of appearantly low performance!

When I boot at 2600mhz, and change the speed to 3500mhz, i'm 100% sure my machine is actually running at 3500mhz, but windows doesn't adapt to the changed speed.

When i launch a game of vice city, it's like the game is on crack: everything goes a bit too fast. Your car feels like it does 300kph, but your speedometer still says 200kph.

An excellent example is an old DOS game without a frame limitter on a new machine: they don't adapt to the high speed.

I hope there's a fix for this error.

my guess is, you put that CPU in another motherboard and it will not perform like this.

like said on shrimp, I can clock much higher with clockgen then when I use the Bios.
I don't believe it.

RichBa5tard · 24th August 2003, 15:53

You don't believe the cpu is running at 3550mhz stable, or you don't believe my system would not crash with a cold boot at 3550 mhz?

What happens if you compare your 4ghz bios oc with a 4.3ghz clockgen oc?

-edit-

If i set clock speed to 3500mhz, and i reset, the post screen says "3.55Ghz". Is that cheating too?

-edit2-

Latest version of cpu-z shows correct speed.

I'm going to compare these two situations:
a) Boot at 2600mhz, oc in windows to 3300 & bench.
b) reboot at 3300mhz & bench

very very interesting what we see here!

I wanna know how this turns out

RichBa5tard · 24th August 2003, 18:07

CPU scaling seems to be ok, and there is no difference between a) & b) in performance.

(In situation a, not all apps dedect the correct speed, in contrary to situation b).

jmke · 24th August 2003, 18:14

difference 2.8 <> 3.0 is almost nihil, but 3.0 <> 3.2 is alot
how come?

RichBa5tard · 24th August 2003, 18:21

You tell me? I'm just showing the test results. All options were left the same.
