frequency (MHz) of yours CT63?

Hi,
what is frequency of CT60/CT63 you are using for everyday use? and what cooling do you have?

My CT63 come at 75MHz and I keep it that way. Cooling is stock heatsink with fan.

I just try to set lower frequency than 75MHz and CT63 wont boot?! (sometimes I get white screen with garbage colors after reset)

---

does anybody manage to "melt"/destroy CT63 with overclocking??

I've always run mine at 80 mHz and been quite happy with it.

95 mhz, with a fan and heatsink, thermal glued to the CPU.

You can see the arrangement I have here:

I've run it for hours and hours and never had a problem with
heating as far as I know.

HTHs.

Darkolord, nice setup

You have at least double sized heatsink

I forgot to mention, and it would be cool to everybody do the same:
My Falcon is in original case.

Mine are all in original Falcon case.
I set them to 95 MHz as they came that way.
But at one stage, I was running at 103MHz so that the ram are at 100MHz.

Just as important is which revision 060 you're using. I assume everyone has a Revision 6? 7E14J?

right, I do hev rev. 6.

@wongck 95MHz in original case and stock heatsink ?!?!! nice!!

Thanks, and yeah - mine has been recased using the Wizztronics rack case.

Yep, I am.

Mine's still tootling along at 66mhz, even though it has a Rev. 6 CPU. I haven't got round to installing the clock mod on my CT60 yet.

My CT63 is in an original Falcon case. Stock heatsink + cooler like I got it from Rodolphe. Running at 95MHz normally, sometimes at 103MHz to see if demos or adapted games get any benfits from increased clockspeed. Everything above 103MHz is unstable.

That "break point" does seem to vary a bit. I can run mine at
100mhz, but as you say, it gets unstable. I get random software
crashes and glitches at that speed. 95mhz hums along rock solid
though.

I've been told it could be memory and other things that determine
the final usable speed, not just the 060 itself.

yeap YMMV.
It's stock fan (I think, no heatsink), no modification except for the firmware upgrade (CT63 & CTPCI).
Mine was the 8th and 9th batch (suppose to be the last batch) with the CPU that been tested to run at 100MHz.

I tried something insane like 106MHz and it seemed to run fine, bearing in mind that i am using MINT and not games/demo.
So stress levels are lower I suppose.

Most stressful for the CPU probably the compiling of programs or decoding the graphical map.

I am running at 95 MHz now as I see negligible incremental advantage on the desktop running higher and risk instability even as they are rare.

I don't exactly have the partnumber of my ram but it is a 512MB PC133 SDRAM made by Infineon.
I think there's a thread here somewhere with some discussion on ram type.

Isn't it suppose to be like this?
That's the default speed on the CTCM.

I do not know. Mine CT63 come with 75MHz...
Obiviusly it is ok to run it on 95MHz in original case and with original cooling as you do not have any problem with stability.

When I had my previous CT60 running in a space case with original cooling, I noticed the temperature ran right into the red @>75Mhz (using the CT60 cpx). The CT63 doesn't have the temp sensor, but using an Eiffel would be recommended.

I ended up installing a huge fan over the CPU plus an exhaust fan in the case. After this the temperature monitor stayed in the amber when running at 95Mhz.

I guess using a larger heat sink would do the job too.

wongck · Post by **wongck** » Tue Jul 02, 2013 1:59 pm

75 MHz sounds like the older limit of the older 060.

Post by **Dal** » Tue Jul 02, 2013 4:00 pm

My old one was a rev 6. I got it from Rodolphe to replace the 060 that was in it originally.

That's the one I've now got

. It's still happy at 90Mhz, I've no tried 'pushing' the clock up from that. I might well take it down a bit if I want to run it on a reasonably warm day. The CPU temperature varies between c.40 degrees and 45 degrees Celsius, depending on the ambient temperature.

Nice to know it's still soldiering on. My ct63 should be with me soon ready to be united with a SuperVidel and set in a brand new whizztronics rack case.

CiH · Post by **CiH** » Tue Jul 02, 2013 10:38 pm

Definitely soldering on

I've also got a SuperVidel, which I'm not currently going anywhere near in trying to install!

Why, Chris?

Why, Chris?

I'll need to refer back to the original owner of this first

http://www.septicsurgeon.net/Hardware_M ... _Case.html

There's rather a lot of 'stuff' in the case as you can see, so I'd need to get help in sorting space for the SV in there!
