OCing like a MaggiFo
Howdy, dudes & dudettes !
During the weekend I found some time and since a few peeps asked for it,
I made some OCing attempts on my G450 ...
I used the latest incarnation of Ashley's PowerStrip 3.0 beta and
was quite pleased with the results.
Here we go:
System:
[*] Asus P2B-S (Rev 1.02)[*] 320MB PC100 SDRAM @ 112MHz FSB[*] Celeron 566 @ 952MHz
[*] Matrox Millennium G450 DualHead 32MB DDR[*] Powerdesk 6.10.013 (public release)
default clock values as reported by Powerstrip:[*] 125MHz core & 166(333)MHz memory
Used benchmark applications:
[*] 3D Mark 2000 V1.1[*] Wintune (V42)
I was able to crank that puppy up to incredible
200MHz memory clock (=400MHz DDR),
which resulted in 150MHz core clock,
but that came along with a sever case of pixel-flight,
i.e. I had false pixels garbling all over my screen ...
Interestingly, the card did not lockup, so I must
presume that the core is good for even higher clock speeds.
(I wonder if MGA Tweak will let us fiddle with clock dividers,
like for the G400, cos then it could get mighty interesting)
Avoiding those digital dropouts, made me clock it back to
180/360MHz memory, which gave me 135MHz core clock (pretty sad,
if you consider, that I had the core stable @ 150MHz ...)
Here now some screenies, showing the clock settnigs I used:
default clock:
180MHz memory clock:
200MHz memory clock:
3D Mark 2000 results in order of 166/180/195MHz memory clock:
(I had the lower the clock to 195MHz, cos @ 200MHz,
3D Mark banged out after 2-3 minutes)
Now some Wintune results in order of default/180/190/200MHz memory clock:
As you can see by the tables above, the G450 DDR is one heck of an OCer
and its performance scales pretty well, until the 64bit bus hits the brakes
(read: pops in as bandwidth bottleneck).
Btw, some of you might be already wondering what I did to improve my cooling ...
Well, I just slapped an old P2 fan on top of my G450's heatsink, nothing more.
Quick final summary:
default clock 125/166(333) core/memory
stable up to 135/180(360) core/memory
core willing to go as high as 150MHz, but being held back by its memory,
which seems to MAX out @ 180(360)MHz and this might change when
MGA Tweak fully supports the G450 with apropriate change of dividers.
So my final conclusion would be that this is an excellent budget card,
offering all you need for daily work, plus it let's you play basically
all games at least in low-res (1024 and below) and there's still some
juice that waits to be activated.
Last thing that you should keep in mind is that despite it's great
OCability, it is still not as fast as my MAXed G400 Vanilla was.
That's it for now and I guess this looks a bit different to the findings that
Tommy posted a few days ago ...
Cheers,
Maggi
PS: I knew I wouldn't make it without any typos in first place ... d'oh !
