MDD Motherboard "Clocking Down"?

according to that link the 1.33GHz DP from a Xserve G4 seems to be the highest rated next to the DP 1.42GHz
Don't take that particular page as gospel-it just shows relative performance under their test conditions. I often get scores both higher and lower than listed in the article. More RAM does improve a Geekbench score, and I've noticed that I often get numbers better than in that chart when I max the RAM in a particular computer.
As a real world example, look at my photo earlier in this thread, where my dual 1.0 MDD scored 908(evermac.com reports 888), my single 1.25 was 784(vs. 727), and my dual 1ghz Quicksilver was 824(vs. 854 report).
Also, there's no guarantee that the dual 1.33 will perform the same when moving from the Xserve architecture to the MDD. I doubt the difference will be huge, but would expect some.
Not sure this will help - but here's more info.
I have an MDD 867 that has been upgraded with a 1.25 GHz CPU card. The resultant CPU speed is 1 GHz (999.97 MHz). The motherboard memory bus chips and jumpers control the memory at 133 MHz, just like when the 867 CPU was in it. Jumpers can be changed to get 1.25 GHz CPU speed, but you can't get 1.66 MHz bus speed with this motherboard - so I didn't bother doing any mods.

my new logic board IS the 167MHz FSB board... came out of a DP 1.25GHz MDD. My original MDD was the 1GHz FW800 just like the DP 867MHz it had a 133MHz bus. However with my 1GHz 133 bus CPU in this 167 board it clocks the bus speed down to 134
OK, so then I'm thinking you need to figure out which jumpers to modify. I found that info somewhere on the web 3 years ago. There are jumpers to cut or connect. (I think the jumpers are soldered-on micro-resistors)
Here's one discussion:

Regarding the processor upgrading what is it that you're doing with your computer?
Are you doing audio/video work? Digital photography work? Using the internet and word processing? Or are you doing the upgrade just to do it. Or are you doing it out of curiosity and to learn something?
I guess that's will yield the best answer for you. If you look at Barefeats or another website that shows real life speed changes between the processors (i.e. movie encoding time, photoshop effect processing speed, etc) with the single processors its usually a difference of a few seconds. In the real world that's not going to be a big difference. As I and others mentioned before the dual processor upgrade is the one that would make the difference.
My recommendation would be to assess why you're doing this. You may be better off just upgrading to dual CPU's or a G5.

a user on here is actually sending me a Dual 1.25GHz CPU card for my MDD. Mainly I am doing it for iMovie. One of the main reasons I don't video edit and only do it when I have to is because with 2GB RAM a Geforce 4MX and a single 1GHz just OPENING iMovie grinds the system to a snail's pace! Also I hope it'll improve my Video watching as of currently I cannot even watch HTML5 video.
The dual 1.25 should perk things up nicely, but don't get your up too high on this particular aspect of performance.
Even my dual core G5 with 10gb of RAM chokes and stutters on Youtube. PPC computers can still do a lot of things really well, but Youtube is NOT among those things.
It will help your iMovie performance tremendously, though. I don't do a lot of video work(just enough to realize that I know next to nothing about it), but do know from real-world experience that the dual processors and faster FSB will lower your encoding times tremendously. Multi-processing doesn't scale directly(i.e. 2 processors don't give twice the performance of 1 processor of the same clock rate), but the upgrade you are doing will probably give you encoding times about 2/3s of what you have now. It might even do better since you are increasing the FSB, upping the number of cores, and adding L3 cache.
BTW, L3 cache makes a bigger difference in the useability of a computer than I think a lot of people realize. Only 1.25ghz and faster MDDs had L3 cache(generally 2mb/processor). I think that's a lot of the reason why a dual 1ghz Quicksilver(with 2mb L3/processor) feels faster than a dual 1ghz MDD.
Yes, I think a good YouTube is really just out of the question for any PPC. I have a DP 1.8Ghz G5 with 2.5GB of RAM and it's choppy. If a DCG5 with 10 GB of RAM can't handle it, then I don't have much hope.
That's cool someone is sending you some DP's to throw in your G4. From what I've seen on BareFeats the DP will provide substantial improvement in the encoding department.
What version of iMovie are you using Matt?

Actually my Single 1GHz and All of the MDDs (from what i read) had L3 Cache. All models of MDD of all speed CPUs had 1MB L3 Cache per processor
IIRC the Dual 1.42 MDD was the only MDD processor to have 2MB L3 Cache.

I can play YouTube Videos with no lag (long as you let the video buffer before trying to watch it) just fine with YouView, MacTubes' HTML5 player or LeopardWebkit with HTML5 on my eMac. I can also watch YouTube with no lag at all using QuickTime Player.
I have the free version of iMovie 6 HD that Apple offered for download before they pulled it.
Theres little ways around all of it, but it's much easier if it just works without having to run multiple apps.
I usually don't have to run multible... YouView (Period) on my eMac and MacTubes (only) on my MDD i use QuickTimeEnabler on other non-YouTube videos.
If you haven't noticed YouView, which was once an excellent program, isn't as compatible as it once was.
I haven't tried MacTubes yet.
YouView works for pretty much everything but VEVO videos, same with MacTubes, I have yet to try VEVO with QuickTimeEnabler...
On a simular note, I read at one point that the Dual 1.25GHz MDD CPU is in fact a factory underclocked 1.42GHz, can anyone confirm this?
I seem to be saying this every week
BUT my DP2.3 G5 plays flash upto 720P on Youtube fine, outside of flash, 1080P MP4 files are fine as well. Even 4K files are playable if they use sympathetic codecs such as Apple Intermediate Codec. BTW my graphics card is the very basic Radeon 9600 and I have 4.5 Gb RAM.
I seem to be saying this every week
seems i need to get my hands on a 9700 then.....
I have a 9600 in my 2.3 Dual Processor G5 from 05 with 2GB of RAM, and YouTube runs flawlessly with TFF and the MacTubes & QuickTimeEnabler plugins. Even LeopardWebkit does a fairly decent job with YouTube. However, my iBook with 1.33GHz and 1.5GB of RAM cannot do YouTube with either TFF or LWK.
well it WAS the 1GHz CPU clocking down the motherboard. After i got home from work today I had my Dual 1.25 waiting for me. here is before and after, needless to say the system is running at 167MHz now. (does that mean my RAM is now faster too)?
P.S How do i get Tempature Monitor to read the CPU temps individually?

Congrats. We now have the same MDD
. Anyway, it was probably the way the board was configured. Since the original processor was a Dual 1.25, it was configured for it and when you put that back in, it worked properly. Guess your set now. What do you plan on using it for now that you have the working board and processor? I'm planning to plug mine into my room's sound system to be a multimedia machine. Of course my hard drives didn't arrive today thanks to the "delightful" postal service.
yeah, it made me nervous because as I was installing it the side facing the ATA100 bus seems to have too much play. Also seeing a Dual 1.25 in person actually made it look like it was a entirely different CPU (a bit heavier too). I also 1st installed it (as a test for the reason i mentioned) with no thermal paste and just 2 screws in the heatsink. Once I found it worked it shut it down and applies some of my ceramic thermal paste.
To everyone who knows the answer:
Is 113F an ok tempature for a Dual 1.25?
Congrats. We now have the same MDD
Well right now I am trying to work out the reason for half my RAM not detecting after the install. What I plan to do with it mainly is video editing (of course i 1st need to MAKE some youtube videos to edit) I will also use it to resurrect my personal website which has been offline since 2008. When I get my copy of Dreamweaver 8 and my iLife '06 should be all good. It is also my music library (right now I am working on converting all the OGG files to iTunes format, to sync the music to my MP3 player (although I can do that with OS X I like how Linux does it (It copies album art via sync) so that makes it much faster than just drag and dropping. Since I have no internet with PPC Linux i have to do all the converting with All2MP3 (Then convert the MP3s to m4a using RealConverter).
on a related note I MAY have fixed the KP problem with Leopard I noticed the IDE cable was loose where it plugs into the motherboard however I have yet to even boot Leopard to test this.
----------
all the computers I have had in the past running Pentium 4s it's Idle is usually about 117F (Have seen some idle as high as 138F though.)
Question is is that 113 the temp of one of the CPUs or combined temp of both?
