I would love to but I don't like to ship all the way from europe to Brazil. If I can't sell them in The Netherlands I will let you know.Quote:

I can do 9*295mhz now :toast:
I'm now running checkdisk because data got corrupted. Finding the max of a Dothan means you get a lot of crashes because 24/7 stable is very close to a speed that crashes the system.
Next try will be 9*300mhz. At 8* multiplier I can't even boot and the system freezes if I try this in EIST; at 7* multiplier I can not achieve a high fsb.
I heard that the lowest multi that really works is 9 ,anything below this just does not work well , i don`t know if it is true .Quote:

At some stage it just "hits the wall" as I've stated in other post(s). For me..with my P4P800 SE and Dothan 730..on good aircooling.. this is 2550Mhz.. It will bench SuperPi at 2660..but no 3D-benches will finish at 2580+..
I've also concluded that VCore over 1.50 is worthless (Bios 1009.004 alllows 1.60..., Bios 1008 gives 1.55)..
As of writing I'm "priming" the chip at 2550@1.50VCore.. for 24++ hours..

11*241 = 2,65ghz
This is one ANY memory divider and they both don't like more than 1,425v. Could this be a mobo related problem :confused:
IMHO, unofficially LV ones should work (but I read some single maybe not so reliable report that does not boot) & should OC nicely (if won´t be there same 180MHz Fsb "barrier" as for C_M is), since would be overvolted by default. While you can not put ULV ones in, since are NOT Fc-Pga package (Fc-Bga instead = no pins!)Quote:

all at the same speeds :nono: surly not all of these cpus max out at the same region ....Quote:

In diagnostic mode it will not recognize a usb stick. I can't use more than 1,5v because my temp rises to 70 dregrees C* ( I need to put some thermal paste on :) ).
I will make a 9*300 Prime95 screenshot if it can do it
ummmmm - I get around 70C load at 800MHz 0.7V cooled by a ramsink (a little tiny 1.5x0.5cm copper one).Quote:

what kind of cooling is that? at like 1.7V 2.66GHz full load mine will never go above 25C ('cept summer - ambient now 18C).
Stock cooler without thermal paste ;)
I don't know if I can trust the temsensor even a little bit.
770m is a bad-ass chip. They can run super high fsb at any ghz or multi, unlike the 780es.....or at least the one I have. A 770 with really high fsb and tight timings on p4c can match the 780's perfromance on ln2. My 770 is the current single card WR holder for x850xtpe in 3dmark 03, 3dmark 01, aquamark3, and #2 single card behind macci in 3dmark 05. Had all these runs been on my solid container, they would be much higher no doubt....Quote:

Also close to 19sec with it for sp1m......with some tweaks I recently learned, that sp1m is mid to high 19's:

and here is a quick 8m...with higher clocks and better tweaking, it's prolly closer to 4 min easy:

I saw your 01 score some time ago - you're not just the world record - you're like 4k above 2nd place...Quote:

01, am3, and pi were on the 770m. Thought for sure I re-ran them with the 2.13ghz chip, but I guess not.
Very nice :slobber: .Quote:

It did around 2.8ghz for benching with the ct-479 aluminum cooler.Quote:

My 4th Dothan is really funny. Prime is running all the time while explorer.exe and system services keep crashing :D
Ik can do 2,8ghz now but at that speed explorer.exe keeps crashing, this is with the 13* multiplier. With the 11* multiplier I have a hard time doing more than 2,65ghz and with the 12* multiplier 2,7ghz is just about stable.
I must say the Dothan is the weirdest cpu i have ever OC'd.
Jep agree, 223*12=prime stable for more then 9 hours but sometimes it just freezes or crashes :D
