Twinmos still rocks...with new motherboard DFI-NF4 Ultra-D, vdimm 4 volt :cool: reach 280 MHz FSB 2-2-2-5 1T.

http://img.photobucket.com/albums/v648/b3nnylase/280MHz_2225_cpuz.jpg

I notice that with vdimm 3.8 volt this memory can't go higher anymore, even i raising vdimm up to 4 volt.

how are you keeping the ram cooled and alive?

very nice though, my cpu/mobo/ram will be exactly what yours is, i hope i can get results as good as yours. ;)

cooled the ram only with 1 8 cm fan runs at 5000 rpm...

holy crap, i just went back and realized thats 1gb, in DC at those speeds...

i've also heard that if you do the 5V mod, and put the vdimm at a certain level (i think below 3.3v), that a certain part of the board heats up.

how much truth is in that, and does any part of the board heatup at higher volts?

no it's not that simple! sandra is affected by the multiplier!
a 12 multi should give 300 points more!

:slobber: I am getting that board. Did you adjust your PSU pots to get the vdimm that high? What did you do? Will the DFI board draw 4volts from your PSU's 3.3 line without any adjusting? :confused:

Reefa_Madness

02-02-2005, 03:41 AM

Doesn't that board switch to the 5v line when it is using the higher voltage (4v) option? I seem to recall reading that, but I'm not 100% sure on that.

Any way you look at it, those are another nice set of TMSP sticks. Benny are you just plain lucky, or do you have a friend over at TwinMOS that is cherry picking sticks for you? :)

kryptobs2000

02-02-2005, 04:14 AM

yeah, there's a jumper to either draw from the 3.3v or 5v rail.

Thats quite simple. The memory controller runs as faster as the CPU does. So a 280x12 2-2-2 will always get more bandwidth than a 280x11 2-2-2.

Maybe you should ask 3dmark2001 about that ;)

Yes it uses the 5V rail for 4V on DIMM.

Anakin_Skywalke

02-02-2005, 10:18 AM

Actually by using the 3.3V rail you can only get up to 3.2V VDimm which is not adequate i'd say. Setting the jumper to the 5V rail one will get the full 4V. Please note that active cooling on the mosfets is recommended if using the latter.

what happens if people start RMA'ing them? not only will that dig into that "saved cost", but it will also be bad PR.

I suppose that they assume they don't need to be actively cooled. Personaly, I believe that those heatsinks applied don't do anything useful. Not enough spikes and fins to do so.

What makes sense to me is that they don't want to follow up abit's MAX cooling on the mosfets because it was not one of the biggest successes as far as efficiency is concerned.

Well DFI and Others have Tested the Mobo before they Went Public. So if there was an Overheating Issue, it would have been fixed. Altho BigToe has Warned if you use the 5v line The mosfets will get insanely hot. i think the 5v is Maily for "xtreme" Overclockers.. No one on air Cooling Will need 4v.
Plus, When you phasechange, it also Cools the mobo and all the Componets on it around the CPU..

kryptobs2000

02-02-2005, 11:01 AM

I used the stock cooler and sent 3.6v to my bh5, cooling the proc. has nothing to do with cooling the ram, you can still go for high memory bandwidth, but even though I doubt I'd add any sinks to the mosfets, I'd probably rather beable to add some nice ones then have some cheap-o crap ones on there from the factory.

Garrett

02-02-2005, 11:51 AM

i HAVE to pick up some of this stuff.I shared that thought... until they died @ 3.6v :'(

craig588

02-02-2005, 01:19 PM

Most other companys thought they would have problems allowing people to use 3Vdimm and above, DFI proved that people are not that dumb and if the memory says only use X voltage, they won't go higher if they can't afford to kill it.

People will be worried about this, but as long as it is set to draw from the 3.3 rail from the factory there really won't be any problems. If it is set to come from the 5V rail by default than there will be problems, people will buy the mobo and drop it into a poorly ventialted case and it will die, but I'm pretty sure DFI knew that and has it set to draw fromt the 3.3 rail by default.

I think I read somewhere that the 5v thing is an all-or-nothing option. You can feed teh vdimm with 5v by adjusting a jumper but it makes things really toasty.

What do you mean all or nothing? You can give up to 3.2V using the "normal" 3.3V rail...

kryptobs2000

02-02-2005, 04:33 PM

He means if you set it to 5v the mosfets will be recieving 5v regardless if you use 2.8vdimm or 4.0vdimm

Yep that's true, although there's no need to use the 5V if you're gonna need less than 3.2V... see there's no point ;)

pik-ard v1.1

02-02-2005, 04:52 PM

if you have adjustable rails, you could also raise the 3.3v line up a bit... but not THAT much.

kryptobs2000

02-02-2005, 05:33 PM

I run my 3.3v rail at 3.9 24/7, would be higher but ovp kicks in at 4.05

pik-ard v1.1

02-02-2005, 05:56 PM

is there ANY danger in that, at all? thats an 18% overvolt, which i think would be out of the tolerance of some hardware... but being able to run 3.6V from the 3.3v line (aka, not heating up the mosfets so much), then i would like to be able to do that, since i have winbond UTT chips...

yes, they NEED to have one little jumper (or wire... whatever) moved to draw from the 5v line.

bachus_anonym

02-02-2005, 06:17 PM

Do we know for sure these DFI boards need a jumper set for the Vdimm to be drawn from the 5V line? From what I read, I was led to believe that 4V is available without any modification whatsoever . . .
You'll get 4v from 3.3v rail without touching the jumper only if your PSU can handle / adjust voltage.
or
You can switch the jumper to draw vdimm from 5v rail and not worry about the PSU at all.

Although, IIRC I've seen OPB giving only 3.7v using that jumper.

matt9669

02-02-2005, 06:18 PM

Then I would suggest that to anyone looking for >3.3Vdimm. Overvolting the 3.3V line not only feeds the DDR MOSFETs but the rest of the board as well . . . and while a .1 or .2V boost is safe, bumping the 3.3 line up past ~3.5-6V could well damage the board . . .

If DFI put that jumper on the board, they designed the board to allow the MOFSETs to operate with 5Vcc. It is a lot safer (and warrantied, not that anyone here cares, me included) than running VIO too far out of spec.

EDIT - looks like the Vdimm might droop under load, which is normal, hopefully a bit higher 5V will fix that - still, if 3.7V isn't enough . . . :rolleyes:

So I am looking to push 3.7v or so through my BH5... Is the best/safest way to do this to:

a) Adjust pots on my PCP&C Turbocool 510 express
b) Switch to the the 5v jumper
c) OCZ booster (I am still not sure how this device works.)

:confused:I don't have the board in hand yet, but electrically speaking B is the best option. I wouldn't use the OCZ booster on the DFI boards, and you're welcome to crank up the voltage on your 510 but I wouldn't crank the 3.3V line to get 3.7+Vdimm.

i've seen stuff supporting what he says... different multi's, even with the ram at the same speed seem to give the sandra different scores... i dunno if its a pattern, like even = good, odd = bad.. or if its actually directly correspondant with cpu speed, or what...
