Hmm, I can't find 780's anywhere. Does anyone know of an online store that ships to england and stocks them? If I can't find one I might ask FUGGER if he can hook me up with one, since he's an Intel employee.

@MOP, nobody has a 780 in stock in Holland...
Not saying I have a good chip, but these are my preliminary results with my 740: It's primestable at 250*11= 2750 with 1,45 V.. needs 1,55 V to be primestable at 220*13= 2860 MHz.. and at 2900+ MHz it boots at ~1,55 V but cannot be made stable even with 1,60 V.. Don't know if it helps you though.Quote:

Which P-M should I buy? from 725 ... to 740, which is the best to achieve some high-clocks on my P4P800-SE? And which RAM?
i would take the 740. The slower models aren't much cheaper and the 740 usually clocks quite nicely.Quote:

Okay! But is it worth to sell my current rig (A64 2,4Ghz, DFI LP Ultra-D, 2x512MB UTT @ 260Mhz 1,5-2-2-5 3,4V and 6600GT) :confused:
Is the Performance much better than now, for example in games...?
:rolleyes:
a dothan is clock for clock faster than a FX.Quote:

And you'll need like a 2900MHz A64 to equal performance (dont know the exact clocks for the a64, so dont quote me on that).
But a P4 board sucks with UTT mem, so you'll need other mem.
2x512mb bh-5 or bh-6 with the same timings will be expensive and hard to get.
Personally i don't think you should sell... well, i wouldn't :)
The performance gain isn't worth the effort you have to put into it, getting the new rig together.
I think the difference is more than 2800 to 2900MHz, my winnie @ 2.7GHz 245MHz 2-2-2-5-1T pulls off 30k in 01 while my B1 PM @ 2.35GHz pulls off 30k and it's only got a 158MHz bus and 158MHz 4:5 2-2-2-5 ram. Both with the same gfx.
2.35:2.7, plus the ram differece...
yes problem is the ram, bh5 is best for it but not so easy to find. UTT sucks balls on it, TCCD ain't outstanding either...
Think I will use this for 24/7 stable and fast enough in games and low vcore.

hmmm
how do you reckon the fan bracket's in this will work with the ct-479?

31minutes for a 32mb SuperPi seems a little slow?. My 730 did this at only 2.6ghz.
don't know why, but the most speed you get with high fsb 1:1 2/2/2/5 ..Quote:

It is the second PM770 i am seeing at this forum . Very fast even at 220 ;)Quote:

never tried low vcore :D but the cpu don't like undervolting .. :/Quote:

I don't see a clock gen for the Toshiba and am unclear as to what mother board this laptop uses.
thanks
Hey guys whats going on. I havent been able to keep up witha ll the new stuff coming out so i figured i would start by asking...What is the best motherboard now for the dothan
p4c800-e dlx :)
So for the past 3 days, I tried to burn in the system via memtest in dos and testing stability before corrupting my Windows install.
System: PM 740, P4C800ED, 2x512 Corsair ValueRam DDR400 2.5-4-4-8 (cheapy stuff) and Ti4200 AGP.
Settings: 257 FSB, 11x Multi (2.827 GHZ) @ 1.6V (max Vcore in bios) with 320 RAM setting (4:3?) ~ 411 DDR (AUTO DDR Volts)
PAT ON
Turbo
MPS 1.4
Spread Spectrum Disabled
FSB Lock 66:33 <- can't confirm on yet as did not boot into windows
AGP Volts - AUTO
Things I've noticed so far (all tweaks in bios) 1023.x beta latest one in the german FTP:
> 257 FSB is not stable no matter the multi or ram divider. Northbridge needs better than stock cooling?
- CPU boots into DOS 2.880 GHZ @ 1.6 (bios) vcore with stock heatsink but is not stable thus the weird FSB + RAM RATIO to keep CPU and RAM @ near their max. Not memtest stable.
Temps are ~ 65 C!!! I need a WC or better HS here. Looking at the Sonic Tower now.
Maybe need DROOP mod.
- Ram at FSB 200 1:1 DDR400 2.5-3-3-8 (stock rated settings) generates memtest errors in test 5 and 6. RAM can actually clock to ~ 230 DDR but errors in the same test. Is this normal or is my ram faulty? AUTO DDR Voltage.
- Should I drop ram speed down to find best 2-2-2-5 setting? I had to get it down to 166 FSB (DDR 333) for the aboves settings to be stable @ 2-2-2-5.
Is there a DOS based cpu tester I can can to burn in my cpu? What settings should I use?
I think I need better ram?
Do I need a better NB heatsink?
Recommendations for a SB heatsink (I don't see any mounting holes)
Windows based test or tweakers I should use?
Other tweak recommendations appreciated.
boot from 201 and cg it up to 257...
@notebook you have nearly no chance, because the ram dont like much fsb, and the pci is not fix'ed. so you can do max. ~15% when you have luck ...Quote:

thanks
the most speed you get with high FSB @ nearby lowest timing [2,5/2/2/x], so 2,7ghz @ fsb 300 @ 2,5/2/2/x is faster then 2,9ghz @ fsb 200 ...
very good LL ram is the best thing ...
