Hey guys, what's the highest ram clock you've gotten with an opty, tccd or otherwise? I gave up on testing my 146 and stuck with 200mhz 2225 and a 2/3 divider for my tccd.

My default timings are 2.5-4-4-10 - but my tccd doesn't work at any speed other than 2-2-2-5 200mhz with my opty. No amount of tweaking vcore, vdimm, dividers or timings has helped, not a different bios and not even an Asus A8R. I used to be able to use the default 2.5-4-4-10 at 300mhz with a Venus. So I figure it must be an issue with my opty memory controller and/or my tccd because a pair of BH5's didn't have a problem going above 200.

Guess it's time to go ram hunting.

2225 are the spd settings for my ram at 200mhz - but even then I had to change the other timings to get stability because at all auto it just wouldn't boot.


Actually the 14x series seems to do fine - but it seems like the memory controller on evethe 16x dual core series doesn't like tccd timings. Getting 300mhz to work on an A64 venus with my ram was a nasty experience already. As for the divider, dude, I've tried them all, also with loose timings but they just don't work outside of 200mhz. I think my ram's crippled - I've had them for quite some time so I wouldn't be surprised if all the testing shorted an IC or something. Just hoping maybe it wasn't my ram.

Anyway guys , thanks for the suggestions.

Heh, I'll need to get some new ram first dude. 2x256 just isn't enough for me to go back and use my trusty BH5's, which never fail to bail me out when my TCCD's being a b****.

I think 2.8Ghz is around the limit on air cooling. I can do that with my opty too but it never passes even superpi and there are too many random errors playing games and stuff.

Eh dude, what's this Biostar Tforce you're using and what divider is that? And I'm surprised new cpu batches can clock so high....

Definitely single core. Dual cores are harder to oc because you need both cores and memory controllers to be stable at the same high speed, which is harder than getting just one core up to speed.
