Icy's Dothan Project

The time has eventualy come and now i own a dothan 740,2x p4c800-e dlx (1 nees new bios) and 3x ct-479 mostly thanks to Gray Mole and his amazing service!

Made this thread so i can ask questions to people and get adivce and to also show my eventual progress once i have finished my cascade. :D But untill then a few pics! heh

Here is the p4c800-e dlx that i bought of Gray Mole and has been modded by persivore with all the mods :D, also the CT-479 that i modded all but the 3.3k ohm mod. Also took the wires out the side towards the top of the mobo for when i phase change the system and also took them from the bottom as to get them out of the way of the hold down im going to use. I want to get a better chipset cooler to replace the asus one but there is no big hurry to do that.

While im building the cascade im going to have to use air or maby water if i can make a bracket to hold the block down. I just dont like the small fans that come with the ct-479's so now its fitted with a 120mm fan. This should be ok for the time being had to mod the fan a bit and also mod the clips to fit nice and neat. :)

Off topic i found this in the shop today and just had to buy it heh. It actualy tastes pretty good especialy with whisky! :toast: also might have to make it into a cs:s spray and Put some slang on there about campers. Also you can see in the background my 24/7 system a barton xp2500+ rofl! super pi time of 48 sec haha soon to be change with the dothan rig.

That thing you made to get the 120mm fan to the heatsink, isn't going to work very well. Axial fans doesn't have much air pressure and that adapter thing causes loss in airflow so there maybe no decrease in temperatures.

well i tested them both and i can feel alot more air going out of the heatsink than that little thing.

the 120mm with adapter is much better than the 70mm, remember its going from big to small, so the air is compressed to a smaller area (and cancels the deadspot) so it will be much better

i could allways put a 230v mains 120mm fan on there lol im sure thats got quite a bit of push to it.

Hey i recognise that mobo :D She's one of me old ones hehe :D

Should be good for 260+ with that board mate, ran that with me 750 no probs. That was before moddage too, so theres probably more in the board :D

Good luck with the clocking/coolin'

rofl amazing how these things get around =)

well my best test results after a bit of playing. I know my ram is crap so thats the next thing i need to upgrade but im just hitting a wall atm. 200x13 @ stock volts is stable(whops forgot to turn down the volts :D) then anything above 205 gets a bit doggy. Any advice welcome! =)

make sure you set the jumpers to 533fsb, it provides more voltage to the vcca (i think that's the name of it) so in theory you can go higher

when I first got my 730, I removed the jumpers and I kicked myself in the balls afterwards (lightbulb came on :) ) cause without the jumpers my max was 220x12 prime stable and now im priming at 230x12 with the jumpers @ 533

hope that helps

yeah the ct-479 is fully modded and is set for 533, wait a sec what ones are 533 is it 5-6 + 2-3?

btw what voltage did you have ?

EDit Best result so far. Also rams running a bit better
http://img154.imageshack.us/img154/4025/test3oh.jpg

I had 1.6 (max in the bios) and just wouldn't do it
now i'm at 1.55 :)

yeah 533 is 2+3 and 5+6

thats not bad at all... get some better ram and you're all set you'll be in the 25-26 area

by the way I notice you're running 3-4-4-8, I was wondering if you knew why I just can't set CAS to 3.0 no matter what I try... the board just won't post...

lower your latency!!!

those are some nice pi scores, get some better ram on that badboy and you should be hitting mid 20's! :slapass:

- oh and have you tried pushing the board with clockgen when booted into your os?

I think that your goal should be this one ;)

Spec:
P4P800SE unmodded
Zalman CNPS7000A-Cu
2x512MB Twinmos SP3500@255.6 2-2-2-5@3.4V via ocz Booster
room temperature : ~5 degrees :p: (the window from my little room was left wide open between 11PM and 3AM :D and ~-5degrees outside)



PS: with the default CT479 cooling and the same temperatures :p: I was only 30MHz lower

well....

you could always try going for this

but then again, you havn't got the cpu speed so try this :)

nice results guys! i really need to get myself some good ram 2x512 sticks any advice on what ones to get that are not going to cost me a fortune? i will eventual get another pair to make 2gb

So guys im probably going to buy some ram over the next few days if anyone has some advice on what ram would work best with this system. im looking for about 1gb to start with pref in 2x512mb chips.

2 x 512mb of OLDSKOOL BH-5 (mushkin blk 3500 lvl II, HyperX etc)

OR,

what I'm using, pc4000 ballistix, £20 cheaper since I bought mine :(

currently £92 new from Crucial and their RMA service is really amazing (main reason why i bought ballistix)

nice with anyluck should be getting some mushkin blk 3500 lvlII 2x512mb,
heres a little pic of my system so far just need to get another tft instead of the crt lol.

what are the timings on that puppy

Razor_Sniper: Yeah its the same chassis but different front and side. From NZXT i think.

Just got this ram from the forsale section.

"Mushkin PC3500 Level II Black 2x512 Old School BH-5
Selling my 1gb set of benching ram.

Tough to find good old school BH-5. Loves volts and won't die.

Purple heat spreaders intact still on Mushkin's famed black PCB.

With 3.6v the ram will do 260-270 depending on the application or benchmark being run.
Maybe more with more volts. I never exceeded 3.6v."

His results with this ram

Ok guys ram arived today. got it tweeked to 2-2-2-5 and runs super pi of 27.5 now @ 222x12. I just cant oc it anymore 223 and it just does not post. i duno what im doing wrong ct-479 adapter pins set to 533mhz, core voltage of 1.6v ram @ 3.3v and it still wont budge. I must be doing something wrong here guys. Can anyone with a p4c800 please reply with the setting/prosses they use for there dothan 740 as i must be missing something. Also i cant find where to set the latencys in the bio for the ram maby im looking for the wrong thing? so if anyone could tell me that also it would help alot.
Thanks! someone PLEASE help me =(

Boot at 201 and clockgen up the FSB :)

also what should the AGP and PCI be at generaly in clockgen?

66/33 up to 300

Then slowly raising with the fsb.

C'mon lower the multi to 9 and push that fsb. ;)

heh i dropped the multi and go the fsb up to 255 max @3.3v i guess with a ddr booster could squeze a bit more out of it.

Also i managed to get 2.7ghz @ 11x246 yey 1.6v i duno what to do now tho. i guess more volts would make it more stable above that. But i think i have reached my limit for just air on stock HS with 120mm fan adapter.

2.7ghz was not super pi stable and was pretty warm,

Managed to get 27.2s time yey but needed 1.65v(multimeter) to get there.

Tbh i dont think i can go much more with this cooling as it was hitting 59'c max when running super pi. Can anyone tell me what the max is for these chips? i really dont want to fry it lol. Soon as i get a better cooler im sure i will be able to get alot more but at least i managed to see 2.7ghz

could this be anything to do with the ct-479 i modded? maby i did something wrong when modding and its not allowing me to go much higher. Also would it help if i dropped the 533fsb jumpers to 400fsb? if so i will desolder them and change it.

thermal spec for dothans is 100C so you dont have to worry about frying it
I'd say as long as you're under 60C you'll be fine

there's something very wrong about all this
I'm on the stock cooler and that sissy excuse asus uses for a fan, and just shy of 2.8ghz. the load temps are around 56C
how much of the thermal compound did you put? I put only enough to cover the core, because I found out that if you let it "drip" over the core it will worsen the temps

do you have another chip at your disposal? the one you have may be near its limit for air since it doesn't respond well to 1.6v+

yeah i only put enough on to cover the core. just changed ct-479 adapter to a standard unmodded one. And get same results. As for the jumpers on the adapter what should they be set at as i cant see a difference when i change them. heh

Ok here it is managed to get into the 26sec area. But thats it no more. Its going to need phase from now on. Or maby buy a 750 or a ES version
http://img238.imageshack.us/img238/7...i2691mb2uo.jpg

Hmm my 750 hits its limit at 2642 (fitting watercooling this weekend tho) and I get 28.7s, ram is no where close to BH5 timings tho - thats a nice score :clap:

Slacken the timings. Bigeth time. Or at least i'm assuming. Also I don't think you should need that much on teh vcore. My 24/7 clock and volt is @ 2.725MHZ on 1.48V all stock HS. Not sure though M8 don't have that board (yet) lol. Might have to check your BIOS ver supports mem timing adjustments. Or you might be overlooking a menu that's only opened when a "manual" adjustment option is set.
