View Full Version : audio probs on silver 50003+DMS3
ive had a dms3 chip fitted but theres a strange buzzing sound that sometimes appears a few minutes in to playing a backup game but then other times the game audio can dissapear completely but returns if you leave the game running. Can this be caused by placement of the chip on the board or wiring?
The DMS3 is very touchy. Probably has some wires crossed that shouldn't be.
Thanks bighap will need to have a look at that. have also noticed this buzzing appear when playing divx movies
Definitely a wiring prob i had the same thing happen to me when i installed my dms3 i rewired it making sure no wires crossed or were too close to chips/components;)
not sure if i should take it back to the shop for them to have a look or have a look myself. could it be causing some games to freeze aswell
yep. Sounds like some wires are either crossed or too close to components on mobo.
decided to have a look myself but opened the case but cant figure out how to get to the board. followed a guide i found but im guessing there is a specific guide for the silver v10. can anyone point me in the right direction.
thanks in advance
Does this problem exist with a Magic V or Messiah 2 chip?

ive heard alot of bad things about the dms 3 as its touchy with the wires and so on. I would prefer a ripper 2

This problem usually happens when the click wire from the DMS3 V9, or M2 aren’t run in a good manor. The click wire is actually a frequency that the chip uses to perform its operations. The DMS3 V9 and the M2 pull this frequency right off the PS2's mobo so if the wire isn’t ran correctly, such as being to close to other components or IC's on the PS2's mobo the frequency can bleed out to these other devises thus picking up that good awful hit pitch squealing noise. This can also he remedied by wrapping the click wire with another wire that is grounded at both ends, but if it is ran correctly the first time this is not needed.
The Magic V scores anther point here because it gets its frequency from an onboard oscillator thus not needing to pull the frequency from the PS2's mobo and dragging it across the mobo. The Apple Pro also has its own on board oscillator.
DMS3. ive managed to find my way in to the mainboard now but not really sure wot to look for. are there pics of any wired examples of a DMS3 + 50003 that i can use

how bout the duo

The DUO also has its own on board oscillator.

has any body else heard about this im just wondering how good it works beign only a 8 wire install i might be able to do that :D
Octapus #8: This is a mod requiring only 8 SOLDER POINTS that allows you to play all of your PS1 and PS2 back-ups with no-swap!

hmm the lowest wire chip i would go to is 14 and thats the f14 mod sounds likee a good one too.
yeah the last i heard about f14 was it was pal wonder if they got them in nstc yet

yea prob its made by team akarua or something. very expensive mod too.
ive had a check at the wiring and moved the clk wire and taped them out the way a bit better. First checked it with some divx movies and seems to be playin with no buzzing, left them running for a good few hours, then just as i was about to try something else the buzzing came back. but what ever ive done with the wiring seems to have lengthened the time it takes for the buzzing to appear. So then tried some cdr backup games and they so far look ok but still some freezing from some of them though im not sure if this could just be bad media or not. The one thing ive noticed is that original dvd games and films play with no problems at all is there any reason for this
I think the freezing is down to crap media...
any brand media you can recommend? ive been using infiniti white tops as i use them for everything else but not sure about the ps2 though
do they do ritek cdrs? ive borrowed 007 everything or nothing DVD andGT4 prologue DVD but GT4 prologue is freezing at the start up. So still not sure as to what the problem is.
I thought i had cured it by tidying up the wiring and taping it down but still losing audio part way in to playing some games. Ive tried some original games and they all seem to be fine can this be because the chip is not being used when playing originals?
Use Verbatim DataLifePLUS CD-R - they are by FAR the best :D
I know with DVD-R it's best to burn at slower speeds (1x or 2x.) Does this apply to burning CDR's as well?

Evo...The oct.8 mod does not nessesairly have the lowest numbers of wires. the only difference between this mod and any other non-swap mod is that it has a chip clip soldered to it. so basically it is like a Dms3 (i am not sure about bootable .exe from mem card but it can be upgraded via cd-r) with a clip soldered to it. Take a look as you can tell that it just has a clip soldered to it. http://www.octapus.net/

sorry..its not upgradable via cd-r. you need a programer to upgrade. i wud not recomend this mod as the best way is to solder all wires and not have a clip.

Interesting design. It’s not a clip as you described but more like the plug-mods of old, that has the option of being upgrades to some what of a solder mod with only 8 wires that need to me soldered to make it totally no swap. Or they have the other 2 setups, the 0 wire one which you will still have to swap just like the old plug-mods, or a 3 wire install which you only have to swap for PS2 games. But they claim that the 8 wire set up it no-swap. Once again not a bad idea, it just looks like hell, and I would be weary of all those extra components hanging off the side of the board, and adding extra gadgets to lessen the soldering difficulty just adds extra variables for something to become defective or work loose and what not.
This post really needs its own thread; we have gotten way off topic.
In fact here is the new thread.

Burn good quality CD-R at the highest speed you possibly can, and providing you have some good DVD-R, there is no reason why you can't burn at the faster speeds. Traxdata 4x is very good by all accounts...
