Hi, I received my DFI855 + PM755 a few days ago, I vmodded the mobo (vddr/vagp) and did the pin mod to have 1.6V to feed the cpu. I use X86's D06 bios, but I think there's an issue with the PCI lock. When I set it to 33/66Mhz, It lilmits my O/C, and if I set it to fsb/4, the issue disappears, have you ever saw that ?
now it's stable at 2.86Ghz, max screen at 2911Mhz (under single stage phase chage unit ;))
the agp isn't locked on the dfi.
Why mildly? ...1.7 Dottie very probably does easy ~2,5GHz wit default Vcore and this doesn´t even raise the temps at all. Why not realize the overhead to the limit... free power no extra cost. :stick:Quote:

dfi will have a new revision out with adjustable Vdimm, working locks and P4 heatsink hold-down bracket. At least that's what I've read.
Yep, they showed it off recently. By the way, the current model is now $239 at Newegg (about $30 less than it was).
for those who don't currently have a dothan board, it's worth waiting, but this new rev is not a revolution, it just makes overclocking easier :)
so is that dfi board out yet? sure sounds like it. also did anyone try it yet and can report on the locks working or not working? else the aopen is still king (in that respect) for now
Look what my friend ian.ho did to our little Dothan over here on the Aopen with my good old BH5 :D

Cooling is just "mild" -40+C phase-change:

Maybe I can get a chance to put this under the Cascade next week.
very nice!!! 25sec with 3ghz is very good for intel :p:Quote:

thinking what fsb 184 with 17x multi (overall same mhz) would do with a 3:4 (245) divider or even 3:5 with tccd (306)?
I dunno I think he did some 8M or above tests... I just walked into the office this morning, saw him with his bloodshot eyes probably from a night of benching, and that bench rig on wheels beside the coffee table :DQuote:

How many V-Core get on the BH-5 for running 2-2-2-5 @DDR580 ?Quote:

they just need to release a mobo without onboard graphics and the boards would probably be +50 bucks less than they are right now...
killer.......
Maybe I WON'T sell my 735.....
This thread is fantastic, so much good information, im glad someone over at FM pointed me to it. Im still tempted to just get a AOpen 855 based one even though i should wait for some 915 one!
Nice OCs LardArse
same here, The P-m seem to be the way to go now. People here seem to knwo their stuff. I was woundering what's everyone's .02 of th enew P-m w/533fsb. The multi will be lower, so if it is still board limited, then the new ones seem the way not to go. I've been reading about the new Aopen board, and i thought i read somewhere when it said 4oomhz FSB, and compatible with the 400/533 p-m. Maybe it was a bad translations, but will the new CPU's run at 400mhz? So the new boards will work with the older cpu's (the 400fsb version with DDR2 Duel channel and PCIe)?
the new cpus like 760, etc. will be running 133 quadpumped (=533) where the old (or better current ones) do 100 quadpumped (=400). the boards to come based upon the 915gm & pm chipsets will be capable of running the 400 and 533 mhz types. it wouldn't make much sense otherwise, locking out not that old stuff... they are designed to handle 533 and dc ddr2 plus pci-e
well my dothan rig is finally on its way
Ordered the DFI board, a Dothan 1.8, a gig of ch-5 kingston hyperX (ram was only A$250 so might as well). I'll take the 6800GT from my a64 rig cause that thing doesnt mind high agp speeds. All should arrive monday.
lol - jka's here - is everybody moving here since dmos got banned?
btw - can anyone tell me the diagonal distance between the mounting holes on the DFI board? Wondering if my chipset waterblock will fit.
the clocks on those BH-5's are amazing :slobber:
533fsb dothans are a serious improvement : http://www.x86-secret.com/articles/c...a/sonoma-2.htm
41*41, you do the math ;)
DMOS isn't banned.
oh? - there was an entire thread dedicated to him being bannedQuote:

That could still be just chance. Maybe they got a particularly good sonoma and a particularly crap dothan...Quote:
