Hello

After many many test R10000 250mhz i find very hard problem in speed cache memory, put CPU infinite LOOP and fail after 8 our, i resolve the voltage 2.6V and i put full work the R12000 in Indigo2 IP28 2 day cpu infinite lood and newer crash, work 200mhz very stable the R12000, not need upgrade Rom Prom, in next day a make other test overclock the cache memory max speed support.

Require many mod the board but i have the first Indigo2 IP28 Cpu R12000.

Tomorrow i make video and add link youtube.

Thanks

Marino

Put video on youtube, full work CPU R12000 in my Indigo2.

Thanks for watch.

Indeed! Congratulations!

Cool !

Here's another good one for when you get bored : the Indigo2 250 mhz cpu into an Indigo (1). Voltage is wrong so that would need modification and the card is slightly too big so you'd have to mess with the case a tad but ... 250mhz Indigo, that would be great !

And it should work software-wise, the 150 mhz swap is a bolt-in.

And if it weren't for the PM3's PCB "nose" bumping into the Indigo's case it would be easy - just wire a 5V-3.3V DC/DC converter between +5V and the standoff leads on the PM3 nose. I guess you can take an X-ray of the PCB and see if there are any traces in there other than the power/ground lines and if not cut it off with a PCB saw, then wire in the converter.

If only my dad hadn't have retired and I could still use the X-ray equipment.

PM5 would be harder, since it has the extra MB of cache memory mounted on the nose. You'd probably need to cut a hole in the case. Perhaps you could disguise it with an "engine scoop"?

tooR,

this is very cool to see what you've accomplished. Do you have any more details on what you modified on the PMT5 to support the 2.6v / R12k ?

You can use any R12k - 200 mhz upto 300 mhz for this I assume??

Looks pretty zippy running, R12k much faster than the R10k??


Too bad it can't go past 200 mhz!

Good work

Jonathan

Must admit, I'd be intrigued to see a few benchmarks of the R12000 next to the 195MHz R10000 to see how big the performance jump is!

i assume that for the r12000 you need irix 6.5?
if so i'm not sure that such a mod, although a great achievement, would be too useful because for 6.5 there're much faster machines.

however with 6.2 or 5.3 for example overclocking and alike would pay off if done to one of the fastest thingies supported by the respective os version

195MHz R10000 Performance Comparison Between O2, Indigo2, Octane, Origin200, Origin2000 and Power Challenge

Hot clocking an Indigo2 is a cool hack but of course not going to win a trophy for best IRIX 6.5 performance. In fact, I wouldn't be surprised if a 195MHz R10K in a Power Challenge beats a 250MHz R10K Indigo2 (both running IRIX 6.2), especially if the Challenge has the 2MB L2 chips.

And of course a (deskside) Power Challenge can pack up to 12 of them. And that's quite a beastie, I can tell you . Plus the mechanical sounding, deep humming of that big blower makes it sound like it means serious business

Of course, with 12 processors on a deskside you can't have the full 6-way memory interleave, so you're trading off some memory bandwidth for additional processors.

it's not clear to me what @TooR has modified, if it's REV specific, etc, missing informations
but I can contact him (I have found his email)

@jan-jaap, SAQ
I have no text book about multi-processor, and any experience with real machine. My machine was an IP30, where I was experimenting only the SMP with 2 CPUs, and … well I have a lot of problem because I can't remove big kernel lock. The other board I have is a mono CPU (MIPS Atlas, mips32-r2 core). Can you suggest me a good book ? I'd like to play with fpga, there I can have up to 4 mips-R3K into a single chip

Hello

I return, i finish project after many month stop, i need now to mod the eprom Indigo2, add support R12k for my Mod hardware Cpu module and add new Rom. I have new version eprom 100ns access latency, read more fast that original eprom found in Indigo2 120ns.

Now i work for finish Rom add portion rom R12K Octane into Rom Indigo2 impact but i need the rom Octane 1 r12k, if possible dump rom ? i don't have Octane.

Last month i mod Rom in my Indy and load Irix 6.5.26m but have many problem to access memory, error random Irix, hard to mod but is possible make one version OS mod for my Rom.

tooR

Hello tooR,
Sorry if this has already been answered, but did you disassemble the whole PROM? With IDA Pro or similar?
Is your listing available?

In a couple month i ready for finish all and i sold the upgrade CPU module pmt5 R12000 and Eprom ROM new version.

I need to decide the price.

Module CPU €55
CPU new €60
2 Regulator + 2 resistor + 1 capacitor €40
Eprom m27c4002 ROM €6
My time for developer rom and mod the CPU.

I think € ??? for all, i decide name Upgrade CriSe R12K upgrade for Indigo2.

Thanks for all

good, thus the above is the reason why you haven't replied my emails
technical details originally promised
(and I didn't want to sell kits, I was just curious to hear)
never sent

Hello

i spend many money for part, mpt5, cpu, electronic ic, programmer, eprom .... and many time to identify the many circuit layer in pmt5. Many test many broken component, i have now only two module full work and many part for production, i not have time available but 2 or 3 our in the night.

I think possible up the mhz the pmt5 to 200 - 233, but need wast time for make several test.

Now i decide to finish the project.

Next project is Indy R5000 to 200 - 240 mhz. I wait CPU 200 Mhz not the original version 180 Mhx.

your language (including italian) is very "hard" to be understood, but it's not the point since it was not a misunderstanding, the point is that you have promised documentation in different occasions while it's clear that you have never had the intention to release

it's not a criticism to "kits for sale", but I don't like to be taken for a ride , thus I will avoid to waste my time with you again.

Hola no soy ni Italiano y mastico poco el Inglès pero Sì yo tambièn soy Ingeniero Electronico como Tu.

Bueno yo soy así mis proyectos no los regalo. Te escribìa por email como para que entendieras y llegaras tu solo peró me equivoquè.

Yo tampoco pierdo tiempo en mi vida.

Saludos y un Abrazo hermano.
