ok.... but i see alot cpu-z pic that show 1.660 with the dothan..
i have this bios.. and i can boot at 201fsb but even with this bios i cant goo over 2590mhz.. why is that??
my dothat 740 number is:
rh80536 740
7452a551 sl7sa
this cpu is good or not?
thanks//
well 2600mhz on air is not bad...
for more v-core you can try the v-mod...
This has probably been asked a load of times before as this thread is afterall 51 pages long...
Would the P4C800-E DLX work with the CT-479 and a 1.6 Dothan without a bios flash to the 1004 bios?
I have no other skt478 cpu's around :(
but i doo 2590 on air and on vapochill xe!! i cant pass the 2600 even with the vapo..
the cpu number is good or not?
rh80536 740
7452a551 sl7sa
I had to hot flash my p4c800e dlx in another board it would not post with a p4 2.8 or the ct-479 with bios 1009. after flashing to 1022.003 it posted first time.
so with 1004 i would say no but i dont think it will do any harm to the ct-479 if you try.

some one can tell me what i need to do to get 1.660v with my dothan 740??
i to vid2+vid4 to vss and it give me only 1.584v!! why is that? and what i need to do to get 1.660 or more volt?
thanks

BTW, post some pic's of how you got the Vapochill head to mount on your ct-479.

ok i do now the vcore and still cant pass 2590mhz :confused: :confused: :confused:
i even give the cpu 1.89v!!!!!!! and still dont pass 2590mhz.. (temp -20c)
what i need to do more to get over 2590mhz?
thanks/ :slobber:
from my experience with dothans they seem 2 jus stop dead at a clock and wnt go anyhigher without extreme coolin, ive gone through 5 dothans all of which stopped at around 2.53, ive now got a 730 chip 100% quad primestable @ 235x12 usin a zalman 7700cu cooler :woot:Quote:

Care to share how you mounted that 7700?Quote:

I thinki very few of then will get to 3300MHz at -20C. I might be wrong though....
ok soo what is the best 730/740/750 ???
and why i cant go to 3300 with my vapo? temp cpu (-20c)??
It doesn't matter, they will clock the same.Quote:

If your CPU will only do 2590 at -20C either you have:
1) the worst clocking CPU ever
or
2) user error
How did you insulate the ct-479???
What is your complete setup, list it here. List your settings here. What ram, what divider?? What startup divider?? Show a CPU-Z of your rig.
C
ok soo this is all the thinks you ask for:
ss=disabled
ram= i do all 266/333/ 233/320/400 dont help (from bios)
fsb=191 dont boot good after that and in 199/200/201.. dont boot at all...
vcore=1.298/1.584/1.660/1.712/1.889v!!! =not help 2590mhz..
multi=6/9/10/11/12/13 also dont help
bios= 1021.007 /1022.003 =also dont help..
somting more? that you do and i dont?
and for the ct-479= is ther away to insulate the ct-479?? if yes how?
i just move the jumper to 533 mod.. also if i dont use the jumper is still 1.73 533bus
the cpu number is:
rh80536 740
7452a551 sl7sa
is that agood number or not??
i hope you can help me..
thanks..
:slap:
what is your ram?
Try about 1.55v, set fsb to 201, DDR to 400, Vagp at 1.70v, performance mode standard, set ram settings to auto-spd. It "should" boot...
You see... when you boot it up at 13 x less than 200, it will NOT OC very well. The KEY is to boot at 13 x 201... it "should" do it, unless you have bad contact on the evap?? But if you say it's at -20C that's ok.
It's a slim possibility that you have a really bad OC'er, but I doubt it.
I noticed my system was REALLY sensitive to ram, what kind of DDR do you run??
I'm on the "official" 1021
also, don't use AI booster, it doesn't work well.
Do you use CPUMSR?

Has anyone put a dothan under dry ice besides kingpin? I hope I can shortly, just need to get the whole BIOS flash without a spare 478 chip and shim thing out of the way...
my ram is crosair xms pc4400 512x2..
the ram is good i can do 12x288fsb!!! on 2-4-4-8 3v!
and i do that and it still dont boot..
i have here a kingstone mem and even with that i cant boot at 201fsb!.
and if i use 1022 bios i can boot 6x201 but still cant pass 2590 mhz..
help me.. :( :( :(
the cpu number is good or not?
Some are just not as good as others. The best superpi 1 mb my 730 did was 2690...and that was with a zalman HS and 1.6 Vcore. Never got above 40C either. Highest 3dmark was 2640Mhz....that was also the limit for superpi with the stock heatsink.Quote:

Maybe some of you that need more Vcore and are running on XP could get a boost with 2K?
ok but you can boot at 201x13? in 1021 bios?
and i use vapechill and not zalman 7700 and i get only 2590mhz
if i going to buy anew one what is the best? 730/740/750/760? to get with my vapo at list 3200mhz?
and i even give 1.824v to the cpu and still 2590mhz.. :confused:
No i don't use that bios, my system is on a p4p800se mobo. Sometimes these P-Ms just hit a wall. I ordered another one...hopefully this time I'll get at least 2700Mhz on air.Quote:

and what is the best?
Like this thread says, and like you have been answered several times, they aren't really different, but if you have a powerfull cooling solution like a VapoLS and some BH-5 capable of, say, 250MHz, a 740 (which would give you 3250MHz) or a 750 (for 3500MHz) would be better than taking a 730 for either 3000MHz or imperfect RAM settings :)Quote:

SOO NOT ALL THE 740 WILL DO 3250MHZ!!
SOO FOR GET 3000MHZ-3300MHZ THE BEST CPU IS 750?
THANKS//
