Whats the best s754 mobo for OCing WITHOUT VMODS?

[Sheograth]

I have a K8N-Pro right now, but i have a feeling its bottlenecking the processor by having 1200 mhz HT. (correct me if im wrong) I have a 3400+ Clawhammer BTW. Im thinking of getting the GA-K8NSNXP. Any good?

Me thinks the new DFI 754 board. Not sure when it hits retail, but it was officially released by DFI

[s e t h]

the early kv8max3 from abit has 3.2vdimm and 1.85vcore. get the revision before 1.2 as from there on they broke the vtt/vdimm tracking so vdimm is only really good for 2.8volts. also the agp/pci busses are unlocked on the abit forcing the use of ide drives as opposed to s-ata.

i know you want no vmods but then wait for the dfi754 board as it will have highest vcore and vdimm.
ther are no-solder mods available for your board.
on your board the vcore mode can be easily done with a j-type smd grabber and the vdimm/vtt can be done using the cap-mod which is doable with a crocodile clip and an adjustable psu.

so the K8NSNXP is just an overpriced over loaded thing?

[s e t h]

it's no better for overclocking than your current board imho

check out my solderless k8npro with bh5
vcore at 1.82 and vdim at 3.53. thermalright sp948u aircooled

[s e t h]

and here are the dry vmods. vcore on the left and vdimm/vtt on the right. a psu with adjustable 3.3volt rail is required. some silver conductive paint can be used to improve the connections somewhat but i didn't need it. the bare end of the vdimm mod was slipped into the 3.3volt rail on the atx connector of the psu.

as you may have guessed i'mnot into soldering up my mobo yet iether

the performance of htt speed 1200 vs. 800 is minimal! Dont change your board cause of that.. ! It aint worth is at all..

Did some initial testing last night and the diff between max vdimm of 2.7(K8ns-pro) and MIN vdimm of 2.7 (2.9 max-vnf-250) is looking mighty promising.

10-2-2-2-1t (2t is bad word)

OCZ bh5 wouldn't run 200 mhz on k8ns-pro stable in goldmemory quick test (I have found this to uncover stuff that memtest and msoft won't)

Fedex dropped the vnf-250 and a hyper6 HSF off yesterday (a day early :D)

Last night ran though almost 3 normal test loops b4 an error AT 210 MHZ (2.7V) :banana:

Higher bandwidth at same speeds in memtest/GM. vs the k8ns-pro

1500+ (CT) vs 1300+(GB) at 200mhz

This bios seems to be tuned for 2 dimms - got higher bandwidth w/ 2 than 1 or 3 (still ran everything at 200 FSB)

This testing was w/ my 3000 NC (no spreader) and Zalman CNPS-7000A (changed the mounting screws to lower standoffs (3/8" high?))
(Love that cooler except can't get a vdimm booster in there :shrug: )

Tonight flashing new bios so I can put in the 3200 CH mobile and see what it will do w/ the setup I really want here. Then back to more system qualification. Gotta play w/ my Adata PC4000 while I'm at it :D (Also the Hyper6 skyscraper) Then there is HTT and dividers and .... :brick: :comp10:

Hopefully goes in the box Wed/Thu and load winders, find out if it still works there.
