BPPC + Mediator & overclocking

Bamiga2002 · 09 March 2006, 09:02

Now that i'm on the verge of getting my towering completed (or not

), one might ask is there a reason to overclock the PPC side of a 240mhz bppc? When i had BVision it was almost a must, but now with Mediator + Voodoo3 the graphics speed should be at a level where overclocking shouldn't be a necessity. It would add to the stability of the ppc also (haven't found suitable 50ns SIMMs) , so tell me you ppc-boasted mediator owners

, should i overclock or not?

keropi · 09 March 2006, 09:33

bah, even if you overclock the gain won't wotrh the trouble... not to mention the risk of damage... 240Mhz is enough

for me, it was more crucial to get a fast 68k than a ppc, that is used as a secondary cpu for "advanced" lol tasks... even mos is not worth that much imho...
as for the mediator, I think overclocking the ppc won't do much good, AFAIK the mediator's drivers are 68k??? so there would be minimal gain of overclocking the ppc in regards to the mediator... correct me if I am wrong, I am not 100% sure of this, I just thought it 10 secs ago...

Bamiga2002 · 09 March 2006, 09:48

I was thinking mainly ppc-based games as Shogo, Freespace etc. these would benefit some of the extra mhz i think. The 68k side is nice to have overclocked, 'cause it speeds up hd & cd-rom access also

. Maybe it's not needed to go beyond 240mhz, but we'll see.

Being too speed hungry will surely give me

edit: forgot that also Voodoo3 can be overclocked...how far can one go with that?

keropi · 09 March 2006, 11:28

ahhh, 3d gaming in amiga.... I cannot even run Quake1 descent on my system.. personally I would not bother to oc just for that!
If I remember correctly, the 3000pci v3, is 160Mhz, and you can safely go to 180Mhz... not sure if that will help either, because the amiga pci implementation will be a bottleneck. mediator or g-rex makes no difference...
check www.3dfxzone.it for voodoo tools... but you'll need to plug it in a pc to use the bios flashers etc...
hey, post a small pic of your tower modification! I am curious!!!!

Bamiga2002 · 09 March 2006, 11:46

Thanks for the Voodoo3 flashing info, i'll post some pics when i get my hands on a camera

Mad-Matt · 09 March 2006, 12:03

Quake 1 should be absolutly fine. Blitzquake with allthe eye candy on runs at an ok 24 fps which is more then playable on my 040/25 603/175 Med Voodoo3. Its Heretic2 and shogo which are only just on the verge of playable. Herretic2 I completed on my bvision, slow at times but i liked alot of detail enabled

Was never able to finish shogo on my BVision as I coulnt get enough fps to get out of a drain with a big fan at the end sucking me in. surly couldnt have been too far off the end of the game either :/. Havent tried it on voodoo. Wipeout2097 runs very nice on Bvision incredably fast on phantom difficulty

. Bit sluggish on voodoo3 though and bloody endian issues on voodoo 4/5

Bamiga2002 · 09 March 2006, 12:26

Can't believe that BVision puts better framerates on the table than Voodoo3...why is that? Hopefully i won't fry my V3 overclocking it to max

_ThEcRoW · 09 March 2006, 12:35

Seeing the actual panorama, i won't overclock a blizzard ppc as they extremely easy gets fried or broken and is the only way to go os4 route. Personally, i don't see the point of overclocking a 68k or a ppc system, since the Amiga os is very responsive even on low end machines, the benefit of the overclocking at most you will see it in 3d games such quake, but you can play it on pc, so taking the amiga hardware to the max it can do is very risky and not worth it.
Just my two cents.

Mad-Matt · 09 March 2006, 13:07

BVision is faster in some casses simply due to the fact it has direct communication withthe ppc bus. withthe med/voodoo, you have to go through the much slower and 68k controlled zorroII bus :| The GRex is faster in this respect also but I havent got that to compare against the bvision. What slows the bvision down is when it has to fit hires textures in its 8mb of ram and also emulate blending modes that the voodoo can do in hardware so in respect to which is fastest solution also depends on the game.

166 MHz, have seen somebody overclocking to 192.

this is going to sound like a stupid question, but can anyone recommend a program to run so I can test if my PPC is working or not? I know the 68040 is working, but I've installed the PPC libraries etc. and I have absolutely no idea of how to test if the PPC is working or not (I don't have a user manual, and the only one I could find online was in German - not my language unfortunately). Can anyone either recommend a program to download to see if the PPC is operational or not, or guide me to an english language user manual for the Blizzard PPC? Many thanks.

Bamiga2002 · 09 March 2006, 15:43

Run SysSpeed ppc-tests, get it from aminet. You can also try a program that uses ppc.

keropi · 09 March 2006, 18:21

well ok, 24 fps is still low for a fps... really, these games suck on amiga... only doom/heretic/hexen are acceptable on their ppc versions... but on the other hand, I am very picky about framerate

Mad-Matt · 09 March 2006, 21:37

thats real picky

I remember enjoying games like rebel assult in the old days with the fps locked at 15 fps, didnt find it unplayable though

Even doom an 68k amiga, didnt find it unplayable even with a full screen 14 fps. I think your too used to the latest pc's playing the latest games at a constant 60+ fps

Bamiga2002 · 09 March 2006, 21:58

Yeah! Shame on you Keropi, you're a naughty naughty...well...uhm...shame on you you SPEED FAGGOT !!!

keropi · 10 March 2006, 07:43

not a speed geek, but at least 30+ fps to enjoy fps... lo

Ironclaw · 10 March 2006, 08:24

I'm a fps freak too, need 50+.... if I play a game, I rather have awful gfx than slow speed.

keropi · 10 March 2006, 08:43

that is so true!

Calgor · 10 March 2006, 15:43

@gizmomelb

Yeah i used sysspeed to test whether my csppc worked or not too.

@Bamiga2002

Please don't overclock the 68k+PPC card! they are so rare, and there is no replacement! In 10 more years time, there will be even less working versions left. Only plentiful intel chips with noticeable speed increases are worth overclocking! (Like the classic Celeron 300A to 504Mhz)
