Single-pipe or Dual-pipe?

the e1705 only comes with single pipe cards, the dual pipes only come on the m1710

but whats the spec difference, any? their must be if one a dual pipe and ones single i cant imagine it just being cosmetic because most people wont even see the second heat pipe.

I don't think there's a spec difference as far as core/memory speeds goes. But the dual pipe one should be able to dissipate heat better, which is good for overclocking.

That cant be all..... thats not enough of a reason to use a 2 pipe heatsink..... Does Dell make mention of a 2 pipe heatsink in the XPS Vs. the single pipe in the 9400? Unless it was easier to use the dual pipe in the XPS it doesnt make sense. If the card runs fine on a single pipe and it still can be overclocked a bit (as i imagine you can still overclock a single pipe 7900 a good amount) why would their be a need? I dont think they plan for people to be able to overclock mroe and they dont point it out as a feature.

I think either theirs more of a difference iwth the cards that we dont know..... or it was easier for Dell to use a dual heatpipe for their XPS M1710's buti cant think of why that would be unless.... the M1710 has a bottom docking port the 9400 doesnt so the XPS uses a bar that goes across the motherboard to the right of the nvidia card, underneath the keyboard it makes it so the motherboard is solid and holds in place while you push the m1710 into the docking bay. (the M90 is only other laptop i know of that uses this) So that bar is neccassary and not in the 9400 series maybe the dual pipe heatsink is neccassary to press against the bar? I'm peicing together a M1710 now and i'll know that part soon.... (btw if anyone has a m1710 palm rest or lid I WANT IT!)


Anyways i'd like to figure this out because i bought a single pipe 7900GS... but i have access to a dual pipe heatsink if i need it...

How much you asking for the dual pipe?

GeForce Go 7900 GTX vs. GeForce Go 7900 GS: Mobile GPU Battle

Does anyone know where I can purchace a dual pipe for my GO7900GS ?

Use it. It will dissapate heat better for volt modding. The main function for the second heat pipe is for the GTX, which runs at 1.24v vs 1.0v for the GS (normally). Basically, single heat pipe = run at 1.0, dual = run at 1.24v. While you can run 1.24v on a single pipe, the card will get hot. Hotter than i am personally comfortable with, but thats just me.

1. There != their:

"People with M1710 have _THEIR_ systems equipped with dual-pipe 7900GS cards and _THERE_ are no known cases of Dell selling 9400s with dual-pipe cards." Don't they teach this in 5th grade?

2. You ask a question and you don't believe the answers; and

3. _THERE_ are no differences other than the numer of heat pies.

Ok, its obvious that the forum is not loaded with spelling bee champs... do we really need to degrade forum members for their spelling capabilities? I know its irritating when you cannot even read what someone has typed here, but mixing their with there? Unnecessary slam...

To the OP. The 2 cards are physically the same in every way, save the heatsink design. Perhaps Dell realizes that the M1710 is the lead gaming notebook? People that are hardcore gamers will more than likely pick up a 1710. SO, by this standard, the better cooling solution should go to the gamers notebook. Real gamers know that heat is dangerous to hardware, so Dell will cater to these people and make sure they don't have heat issues to call up XPS support about. The XPS chassis was designed with a dual heatpipe GTX in mind. I suppose it just makes sense to have consistancy across the platform.

I know I could be wrong about Dell's intentions, but there are still no hardware differences between the two. I suppose Dell just figured that since XPS users are the big gamers, that they deserve the better cooling solution. This of course, compared to the 1705 owners whom Dell would consider to be "occasional gamers", or business oriented people who need spreadsheets first and gametime second...

I didn't "slam" but merely explained the difference using an example. People frequently confuse THEN with THAN, THERE with THEIR, as well as improperly use the apostrophe in spelling the plural and possessive. If anything, I am helping the guy out should he happen to make similar errors when/where they will not be tolerated

Can someone give me some help.
Where can I curently purchace a dual pipe for my overvolt 7900 ?

Thanks

Dell spare parts. If youre lucky.

Alrighty, Mr. Big. Here's a tip: sentences end with a period.

Play nice guys.

...or with an exclamation mark... or with a smile just like my sentence did By the way, "alrighty" is not a proper word; slang does not count.

Just so you know, you put a space after "...".

"... or with an exclamation mark..."

Just as an example. A lot means "a lot": "A lot of pancakes." Alot means nothing, and therefore is not to be used under any circumstances. http://web.uvic.ca/wguide/Pages/UsAlot.html Anyways, why are you guys fighting over grammar?
