I think you guys know far more than the average DCowner.... too technical.
I had mine OC'ed, but the chrystal could handle two frequencies, need to replace it, cuz the OC didn't work, the original signal was still ok.
Bump
I am thinking of using ThermoElectric Peltiers for cooling.
Sub zero temps ftw :DQuote:

Make sure you take the proper precautions with a TEC though, they can be dangerous, and need adequate cooling on the hot side, a socket A HSF at the least.
I get the impression that it's not the SH4 thats holding the OC back, but some other component that is clocked from the system bus. And I think 300Mhz is impossible to hit without first figuring out what that is. As you said, the RAM is a possibility. You could transfer that 8ns RAM over to one of your other DCs that OC well. Google for the Xbox RAM upgrade to see how to solder RAM using a basic soldering iron.
Good luck with the TECs :D
btw, if you're wondering why I'm here, every now and again I check in the dcemu hardware section :o
Yeah, I'd rather shoot myself than do that sort of soldering ^_______^
Even if I could, I'd just pull some 5.5ns RAM off of an old Voodoo3, thats 183Mhz rated.
Also, I'll be running them on low low voltage. I just need it to cool better than the current solution.
You'll be cooling the RAM?
Thing is, RAM is the same as northbridges etc. improved cooling does little for better clocks. As long as you're dissipating the generated heat (RAM sinks etc) then you wont see any improvement from going further.
A volt mod for the RAM would be interesting, but we'd need a volt mod for the SH-4 first, lol.
Hey Morph- how did the 8ns ram do?
For cooling, check out:

All your needs and guides.
However, I don't think that extreme cooling will make significant (10MHz+) difference unless the voltage is increased -any progress? :confused:
PS: the corrupt save problem due to asynchronism was solved by OCing the vmu :thumbup:
How do you OC a vmu?
btw nice to see ptr.exe is still alive <3

Sorry, I've kinda lost interest as of late. I've been busy with my computer hardware and the stuff related to that.
