Dothan overclocking thread

[charlie]

Yep, looks like 0,09µ process & Dothan core design has a limit @ 3GHz even with Phase cooling!

But "miraculously" on LN2 they can go to 4gHz++ at 1.65v...

My Dothan is benchable at 3106mHz @ -65C

What was it benchable on moderate air cooling? you have 750?

I'm hoping to gain like 3G bench with chilled water. Only 120Mhz to go. Besides on water the temps @load would be realy stable. Same WC holded my Pressy @4.3 @8c load. Thats like atlest 150W of heat. Also with this 730 my temps in the box just stay on same level, much less heat. Onother part is that my PSU rails are also got stable as hell 12v is @ 12.22 @load and it use to drop to 11.67 with pressy.
Anyhow i love this setup. This is a truly overcloker dream cpu.

On air I'm good @ 2800ish... and yeah, it's a 750.

Few screns to support my words.
First one is on regular air stock heatsink 50c @load. Second with chilled air stock heatsink -11idle/2c. Third oh hell 25c patched SSE2 PI just for fun.

The mem timings hurt my PI performance. These are good chips Hynix b5 280mhz stable only @2.8v but wont hold tight timings. Best i could do is 2.4.3.8 @240 mHz. With 3.2v max i could probably go pass 300 but i dobt there will be a need for such with my setup
I will need to sell them now.......

1GB of OCZ EL DDR PC-4000 Gold VX memory with OCZ Booster are on the way ;0]
You think those should do well with my MB? Man i hope they will, I serched OCZ site and it says they are "compatible" With natural cooling they will get in the chillbox i hope i can up the voltage quite a bit

Low timings DO matter. I gained about a second in superpi when going from 2,5-3-3-8 to 2-3-2-5

I was thinking about TL stable 24/7/365 even 100% load & on summer ...
[ I am not interested in showcase-record achievements & passing benches, but it is nice to see them too ]

[wwwww]

anyone had any problems with an x800xt on the DFI board? Seem to only get around 20k in 01 and 10k in 03 with it at 633/570. Had the same problem with an X800pro VIVO @ 16x1. Getting like 27k with a 6800gt though. My fillrate on the x800 is wwaaaay to low as well - onyl around 7.7k. Only thing I can think of is the 4xAGP but I dunno. Anyone got any ideas?
