Nothing is ever quaranteed in overclocking it's all about luck. When you buy a 740 or 750 it can do anything from 2200 to 3200 depending on how lucky you are. The 750 is the same as the 740 only with a higher multiplier which would make booting more difficult.Quote:

I have RMAed it and lets see if I get a new one .... I think I just had bad mem controller on the chip.... :mad:
Got my 730 + CT-479 + P4P800 SE + 2x Corsair CMX512-3200C2 all together. (Typing under Pentium M power :) )
I can only get to 155 FSB before it craps out and resets itself. (Asus'es CPU Parameter Recall etc..)
I'm using the beta bios, I have vcore options with it. But no multi option, I want to drop down to 10 and then boot at 201. I want to hit 2 Ghz atleast. Should I jack up the Vcore? 1.5v or so?
Where do I go from here?
My potential order of operations (Point out anything wrong)
1. Boot at 201 fsb
2. drop multi (CPUMSR or EIST?)
3. Use clockgen to adjust
4. Use I865 tweaker
???
Thanks

Any ideas to boot at 201 FSB? It seems volts is not the problem....
EDIT: Just rebooted and played with the bios. Took a chance and it boots at 201! I'm off to bed more fun tommrow night. 2.4 Ghz on a 1.6 chip is enough for one evening.
Interesting problem I've discovered on my P4P800 SE, a fsb of anything between 153 and 176 will not boot. 201 seems to be fine. AGP/PCI lock is a godsend.

Had anyone tried a P4GD1 with a CT 479 and dothan? I think it will be a good option because i don't wanna go back to AGP...Isn't? :stick:
yup... karemat tried P4GD1 with CT-479 and got some nice benches.
Finally finished screwing with my 2.8ghz Venice and now I get to play with this bad boy. Looks like 2466mhz @ 1.35vcore. @ 1.4vcore I can get up to 214FSB (2566mhz), but if I move any higher I get an almost instant reboot. Also, it wont post (locks up on post @ 225) or run memtest (locks up in memtest @ 220) above 215. I'm running 1x512 UTT right now to minimize variables, and memtest runs fine (no errors) at 215, but locks up at 220, regardless the vcore. Has anyone else encountered this problem or know how to fix it?
I'm still on stock cooling, but as long as I stay below 1.45vcore my temps are good.
It's the UTT... it doesn't run on P4C/ct-479 at ALL!!!Quote:

Thanks man. I'll try my generic elixir. I'm probably going to sell my A64 and keep this sucker if it performs in COD for me, and if it continues to scale. (If I can hit 2.7ghz with my slk947u, I'd say it's almost certain I'll be keeping this rig.)
It's sad really. I bought this UTT. Got a good price on it ($105 for LL ram). It performs like there is no tomorrow (240 @ 3.0) and I just can't find a place to use it. Might end up in my old NF2 rig.
heck, you'll hit 2700 pretty easy. Another big thing, these rigs don't work well unless you boot at 201, make sure you do that...Quote:

Intresting note there charlie.
Update on whats happening here is that I cant get it to boot up. Still on stanby :(
Bios hasnt been flashed on the board to the latest one that supports the Dothan's... 1009 is it?
I am running 2x512MB OCZ VX 4000. I'l try the 2 sets of old skool BH-5 Ive got to see if that does any help.
Charlie did you have to use a normal p4 478 to flash your P4C800-E dlx or did the CT-479 work right away?
My setup is:
P4C800-E DLX (stock bios)
1.6 2MB 400fsb Dothan
CT-479 w/ Asus hsf (no socket mount on my p4c800-e so the Asus hsf is held on with cable ties and rubber bands :D)
2x512MB OCZ 4000 VX
OCZ 520w Powerstream

You need a normal p4 to flash with.
Not the news I was looking to hear.
1009 bios right?
My dads rig will have to be taken apart to get his P4 out...
You will need BIOS 1021, and you need a 478 cpu to flash it :(Quote:

Thanks Charlie and Lithan for the info.
This VX has'nt lasted long :p: 3 Days old and not even used...
My old skool bh-5 it is then with my dads P4 2.2a :D
which modules today use BH5?
You need Original BH5, not the UTT bh die stuff. That is why the reference is to "old skool bh-5". You've got to visit the Classifieds if you are wanting to find any.
None of the UTT ram will work very well with the Dothan/CT-479 combo.
My UTT works fine up to 215. No matter what ram I use I can't get above 215. I know it's not the board, memory, or cpu's mhz limit. I suspect it's a limit of my adapter.
I switched adapter to 133. Was at 100. Now I can only post at 210 or less. Installed CPUMSR and changed to 10x, now I can adjust FSB in windows past 215 though (at 230 now).
Edit, seems that I can get 100% stability easily at 2500, we're talking less than 1.4v, but if I try for 2550 at any voltage and any fsbxmulti combo I can't even post or I get an immediate reboot if I set it in windows. Anyone have any ideas?
you can try the new beta 1022.003 with multi at 6x from boot...maybe like this you can climb with fsb..ah, are you 5:4? you can try maybe...
I've tried every mem divider available, and Im using a p4p800se.
