but hopefully it'll be cheaper for the people who didn't buy a 2900xt/pro

Any news on HD2950XT?

It wasnt as if they were bandwidth limited though.
Agreed they had more bandwidth than a gtx but was slower, so i would think there is some head room in the bandwidth to cut it down if it means a cheap card at about the same speed to go against nvidia then that what they will do.
Ahh shame
. I think the progress you are seeing is from increased sm2/sm3 scores which is happening with the same overclocks on the GPU but faster CPU speed. It seems we are CPU bound a little in comparison to Conroe systems as if you had a Conroe at lets say 3.4Ghz then your SM2 and SM3 scores would be better at the same GPU overclock. I think if you had access to voltages that a core increase would improve scores.but that won't say what the safe max temps for my cpu..
I think it's 71'C in Coretemp and that usually reports back about 50-55'C in programs like Everest/Speedfan etc. This was on a much older version of coretemp and also on the 939 platform in my case.
When I run a CPU stress test if my CPU goes above 71'C or 72'C the stress testing fails on one of my cores and it's heat that causes my stability. One of my cores is a beauty while the other one is an ugly sister.
What I'd do is just keep messing about with it until 3dmark crashes on the CPU test. That would mean that you are just past your limit so you could just drop back to the last configuration that worked and stick at that until you do an 8 hour stress test. Do not go above 1.55V though. You could do a benchmark at 1.6v but the gains would probably be minimal and the heat would be too much (most likely). After you're finished with the benching side of it then do an 8 hour stress test while you sleep. This way you'll know what's stable for 24/7 use.

Try and keep below 60°C in coretemp.
Is it lower for AM2?.
Aye, I'm the same. Are you AM2 though?.
my cpu is AM2, so are u sure 60c? and do u mean on each core?
My cores ain;t happy if they go over 53 degrees
And one on mine is a cow. Only one gets to 53 and the other sits happily at 43. That's what's stopping me get past 3.25Ghz
[EDIT] I thought you had AM2 for some strange reason. That's what happens if your typing, on the phone and having a herbal roll up at the same time
. Was this using Coretemp though as that is way too low to fail as 939's have to hit past 71'C in the core to fail a stress test IIRC?. Shame to hear about the naff core though. I think AMD done this on purpose so everyone wouldn't buy lower versions 
[/EDIT]Ahhh. So these have lower volts than 939 and a lower temp cut off point because they are cooler?. You are talking about Coretemp though?.
As AM2 wasn't up to much over 939 I haven't really learned much about these CPU's.
What voltage do you run for stock clocks Gareth?.

All of these are reporting 3.2Ghz for their max OC
. Either you have a great new stepping or your lucks on the up.
I think it's just the same as in overclocking 939 so just keep it under 70'C through Coretemp. Temp reading programs that do not do the core will report back roughly about 50'C - 60'C but coretemp is the only reading you need.
Set it at the speed and voltage you want and run a 8 hour stress test (small FFT's). If a core gets too hot it will fail the core anyway so you won't wake up to a melted PC.
What I do is sit and keep my eye on it for the first hour. If the temps are under 70'C after the hour then it's more than likely to make it through the night and I just awaken or return to see what's happened. If it failed I would set it back to a working overclock for that day and then do another stress test when I sleep again.
I'd stick to the volts I mentioned until you feel more confident. 1.55vmax for now(If you ever need it).
