Getting ready to SLI the 460, but whats the V2's?

post #1 of 6
Thread Starter 
So one gift I'm getting this week is another GTX 460. (Yesssssss! biggrin.gif ) I'm currently using the 266.58's as they don't give me problems with Folding like the newer drivers do and my performance in games already is great. I was thinking about updating drivers, but idk yet. So I went and looked at the drivers list and saw 2350987 different types of GTX 460 versions. But what caught my attention the most was there was something called GTX 460 V2. So I looked it up and saw it was just higher clocked and had more narrow mem. speeds. Currently I have a GTX 460 E.E. that is pretty new as I RMA'd my casual 105C burning other E.E. I have it overclocked and all but my question is that when I get this new card, if it is a V2 (which I'm not sure I don't think it is.) will I still be able to SLI with it?

Here's the card thats coming in the mail to SLI with:

You SHOULD be able to SLI these. They're only 1 part number off "01G-P3-1371-AR" vs "01G-P3-1372-AR", and the EE just means "external exhaust". I would be pretty confident you can SLI these together. I would put the newer/faster card in your top slot, so that by default you'd be using the faster card.

Okay thank you! I was actually just gonna keep my EE in the top slot but I'll see how everything works out and I may have to move it to the bottom like you said. I was also just gonna overclock them both to 820MHz. (My current is 825 but I'll just drop 5Mhz) w/out voltage overclock as well.

You won't be able to SLI them. Looks like the v2 has lower bandwith than the regular 460, so they're not gonna work in SLI. Not sure if it will work with a 768 since they'll have the same memory bandwith, but even if they do, you'll only be using 768mb.

Nvidia GTX460 v2 uses 192-bit memory interface width and based on GF114 while the GTX460 uses 256-bit and based on GF104.  So, they cannot be SLIed.

Reference link: http://www.geforce.com/Hardware/GPUs/geforce-gtx-460/specifications

 

However, the link above (ie EVGA GTX460 Superclocked 01G-P3-1372-AR) is not a v2 as it has 256-bit.  So, this card should be able to do SLI with your current EVGA GTX460 EE.

 

Looking ahead, I have two comments:-

1. It is better to put the current EE card in the lower slot of the motherboard and put the new card in the top slot.  This is because the new card exhausts heat via both its front and rear.  Hot air exhausted from the card's front has a higher chance to be recirculated (by itself or by the EE card) if the card sits in the lower slot.  Of course, you can try both setups to actually see the thermal performance.

 

2. The Rosewill RG630-S12 has one 6-pin and one 6+2 pin PCIE connectors and so this is not enough.  You will need two pairs of 'two 4-pin molex to one 6-pin PCIE connectors' for the second card.

Yeah once I looked at the link I saw it was 256bit so it should be fine.

Answer to 1: Currently I have a GTS 250 that folds 24/7 on the bottom slot and I have no issues with heat but I may do that/ I'll see how temps are before and after. May possibly switch it to bottom.

Answer to 2: I looked in my case and I think I have enough that came with the case and one with the PSU not being used that should work okay. Hopefully I won't need to buy more adapters. (Just checked the link. lol i have like 4 of those adapters. And some come with the card. I'll be okay for sure. smile.gif )
