Hi im looking for help.

iv modifyed my Bvisions and i need to test card beyond 100Mhz with OS4.0 the cards work fine with CyberGraph X OS3.9 @100Mhz+.

is it possible to overclock the card with P96?

PICASSO96MODE the PREFS can i use this to overclock the card?

any help will be welcome.

thanks


WARNING! do not try to overclock your card my card(s) are modifyed for this.

@delshay

Maybe you can consult the P96 manual if it is on Aminet somewhere. But the appropriate tooltypes are probably OVERCLOCK and/or MEMORYCLOCK. Whether that works depends on the driver: Elbox drivers for Voodoo PCI cards do support overclocking.

UPDATE: PCI bus now working beyond 41.5Mhz now only SGRAM is holding this project back.

NOTE: this may not work for some or all users.

I have now updated OS4.1 with all the updates,does anyone know how to get Bvision overclock working.

A step by step guide would be very helpful thanks.

3DLabsPermedia2.chip 7.33 permits overclocking, but I don't think it has been released. And I certainly haven't documented how you enable it, either.

Thanks for reply awaiting new release. Advanced configuration is also welcome to take advantage of faster low latency sgram.

Looking at the permedia 2 documentation I notices there is a range of parameters that that can be changed also to take advantage of faster sgram. Perhaps in the future if it is possible a utility for novice and advanced users could be useful as all Bvision users.

All Bvision do not all overclock the same. This is partly down to different manufacture sgram fitted to the card as standard which some users had different results under OS3.x.

Web search has shown that some PC GFX card that use permedia 2 chip come as standard with 125Mhz sgram and is shown to overclock at 120Mhz and has proved to also work here on Bvision.

Also note test here has also shown 125Mhz or better sgram is also needed for higher than normal PCI bus speed for Bvision.

I did a GFXbench2D test and uploaded it and I can't believe it my card is last sitting right at the bottom (last).

The first benchmark test my card is on top even against the mighty Cyberstorm but its all downhill from there from the first test. I'm not too concerned about the other test results as I know a faster PCI bus will improve some of the test results.

Blizzard PPC @300/060Mhz (card is not overclocked).

More than 30 % (read) and 40 % (write) video bus speed increase. Good work!

Test was done on a slow test card. For sure another step-up in performance is also in the works if I am able to fix some outstanding issues.

overclocking do tend to make some stuff faster but other stuff slower , no?
i seem to remember something like overclocking the 060/50mhz MKIV blizzard board to 66mzh and even up to 72 ? but memory speed went down... sorry it's like 10 years ago now and my memory is ...well.. not what it used to be.

i know you work with more than oscilators and i did see that screenshot but i am wondering if there's any catch to all of this... like does it break compability with programs and games (when overclocked cpu and gfx chips etc?)


PS: how many chips have you fried ?

See the basic standard modified Blizzard card (no overclocking) but it still has a higher performance than some overclocked card(s).

Any speed-up (if-any) will be added to the new standard modified card overclocking is not allowed and is forbidden.

http://www.amiga.org/gallery/index.php?n=3692

During testing sometimes things do go wrong,but this is what testing is all about and Blizzard card is tested on long runs. When something does go wrong its not a problem,I just look into what caused it to go wrong and repair it,then re-test.

The standard has already been set for modified cards but there is improvement on the way and I am awaiting the new Permedia 2 driver which should see SGRAM on Bvision clocking at 125Mhz as standard if driver is not limited.

Everything is tested and is 100% working as it should no side effects ie crashes,lock-up ect.

Standard basic modified card is ultra stable,this is why it is tested over long runs and is modified to work in a desktop A1200. No modification needed to trap door or needs extra feet,it modified for direct plug-in and play and has on board cooling just like the Bvision.

shame i didn't know who you was back in the early 2000's .. 2000 my blizzard 060/50 fried and a year or 3 later my blizzard ppc 240mhz with 060/50mhz and scsi died.

bought new (used) ones but as you know... prices are steep and you never know what they had gone through before i got them.


anyway, what is the main goal for your tweaking and thinkering with these things?
Really cool to hear that these things are tester and meant for as standard desktop A1200 and not some frankensteins monster tower like my RBM tower

also..maybe you know, wasn't there supposed to be a new 060 board released a year or 3 back?, i think it was from Jens but i never found any more info other than some A600 or 030 cards etc.

Are you running Linux on your Amiga? What is this AUX partition?

Test was done on a test Blizzard card. I am not concerned about the other benchmarks as this time as I already know what it can do and has already shown triple digits for ram and holds world record on all classic amiga.

No matter how fast classic amiga is,is what is seen on the screen and how it is performing at high resolution. I have already seen what it can do with some 3D games @1024x768 and I was a little stunned that the Permedia 2 can perform at this screenmode.

I've only seen pie in the sky hopes about 060 or FPGA softcore from people who wouldn't be able to make such cards. I think the only thing, I think, Jens has said on the subject is that an 060 board would be too expensive to produce.

There is UltimatePPC but that has an 040 and a PPC CPU that isn't particularly useful in Amiga's anyway.

I also dislike classic tower A1200 this is why I stuck with my desktop,but hold on where does the G-REX jrop into all this,thats the interesting part,if and when I do get hold of a G-REX. ...expect change.
