pewww...has gone fishing on the net for the guide...found none...the only one found...is non-dual channel...which is using dimm1&3...very discouraging...but finally...i tried it my own way and voila...managed to put the chunk of stick in dimm4...with about 1 mm space between the tip and the heatsink...so now running on dual-channel...but still not stable la...dunno what's wrong...sometime when entered the bios...it just hang...but some times only not always...need to re-check again...anyway...need to memtest my mem setting now...ciao

what ram are you using?

Twinx1024-C2Pro Rev.4.1...u just can imagine the hassle i need to go thru to install the stick under the xp120 wing...
anyway...my system is stable now...but just pushing the cpu/mem a little bit...220@2336...havent got time to fully concentrate and today i'm off for two-day workshop...damn...
hope to run at 2225...but no luck yet...a lot of tweaking has yet to be done...any tips???

just fixed up my DFI nf4 ultra-d with vitestas ddr 500 and x850xt pe last nite..everything boot up nicely...running pretty fast(compared to my p4 3ghz) and 3dmark2005 came up nicely at 6.2K...apart from the major gripe about the bridge heatsink being placed too close to the pci-e slot, not much complaints...oh yeah..and the funny pattern of having the DIMMS in slot 1 & 3 ONLY for dual channel..doesn't make sense ....will try OCing tonite and see how much I can go...currently burning the stuff in....hope things will go well

Any dfi nf4 user who have use the Vdimm~4v before and pair it up with the OCZ VX ram? Do the mosfet being very hot after vdimm go above 2.8v?

even at 2.8vdimm
the mosfet is hot

i tried touching it with my hands once. One of the many stupid things i did. it was very very hot.

woo... 2.8v also can goreng telur dy, then what if the OCZ VX been used on this mobo which need around 3.6v to optimize the performance? Did you guys try before to use a fan to blow it or replace the stock heatsink with a better cooling. I planning to build a system with this mobo together with the OCZ VX ram and i worrying about the instability at high vdimm due to the heat produced.

Most mosfets are made to withstand super duper high temps (in excess of 100C). No harm sticking a small HS using AS5 adhesive though if you're worried. So far there's not really any increase in OC or stability but I guess it gives you peace of mind running at those extreme levels

As for RAM, its always a good idea to use a fan to cool them. It may help with stability at higher FSB's/vdimm.

tried that already...got that from dfi-street...but working for me...need some tweaking...but that can be use as a start...will tweak again 2nite, once got back...still at the w'shop...thanx kianwei

remysix:
ahah i totally understand u man... same thing here
the thing is if u install the rams first, it will block the installation of the xp-120
then if u install the xp-120 first, dimm4 is blocked...
ahaha until the end we have to wrestle our rams in

i'm running my UTTs at 3.5v
yea the mosfets are real hot (~50c)
even with a 100cfm delta on the xp-120 partially blowing the mosfet sinks

luckily i didnlt give up...
what proc r u using yennshin...and how's the ram and ocability...

i didnt know XP-120 gives so much installation trouble... i'm still on stock heatsink.

it was hell coz my ram is twinx pro series...it's too tall compared to others...

DDR600 RAMs anybody? Works best on DFI NF4 motherboards

Yeayyy! My dad just returned from Malaysia with my SLI-DR mobo!

Just waiting for my CAA2C to arrive and I can start with some overclocking goodness again!

welcome to ta club!

My proc? It's a 3200+
CBBID 0502

not really ocable, max stable at 2.4Ghz
the RAMs are great though,
currently tested at 254 2-2-2-8-1t 3.5v
but needs aircon coz the mosfets gets too hot

i use a portable air cond and blow directly into it. get one and try it.
