c) everyone thinks you need moar psu than you really do around these parts ...

I'm only gonna run this setup for at most 29 days, so, as long as it works for what I've got going here for that long, I'm not too worried about 'cutting it close'. If this psu 'died from exposure' here I wouldn't be heart-broken anyways ... I got it for like $100 on clearance, the fan is a little noisy and it's not modular ... I'd kinda like a good excuse to buy an Enermax Revolution

Grunion:

Wow, that is a fantastic overclock on a 295 ... yours is the sandwich? I can't even get near that high except on memory ... you got an overvolt running on that bad-boy or something?

Nope

Doesn't work with my card/drivers.

I can only run that speed on a select few games/benches.

Grun: you're tellin me you're running a sandwich, with no volt mods, on air, @729/1566?

Srsly?

I've never seen anyone get anywhere close to that with one of these cards bone-stock. What does RT say your voltage is at? Maybe XFX does an overvolt stock or something, cause that is CRAZY, man ...

My bad 1512

I did a no AA run, strange results, it's like the Sunshafts run doesn't use AA.

Did you also turn on the A-tested DX10 AA like I did on that test?
Besides q-sli not working I got something else funky going on w/that test, cause the first three tests always bog down when the camera is moving into the clear sky camp (that's where those 8-9 fps mins come in) but then on test three, the hardest one, it doesn't happen there. As we can see, on that test, our mins are almost identical.

There's no logical reason I can see why, even w/only one 295, my mins should be like 4x lower than your tri-sli rig ... unless, at that point in the test, the mem usage is shooting up over 896MB or something ... if I could get RT working in Win 7 I could check this theory, but I don't think it does, does it?

Edit: Damn, I just went through all this rigamarole to finally get RT working on 64-bit Windows 7 ... only to discover the one thing I care about right now, which is monitoring vram usage ... cannot be done in vista, apparently due to something called vista videomemory virtualization.

How friggin annoying ...

I can't remember. I did that bench back when NCSpec and myself were battling in that epic thread. I don't have the benchmark anymore so I can't redo or check it.

I'm, sure that it was dicussed in that thread though.

So get the benchmark, man! It's not like it cost$ or anything ... 'tis good to have around ...

It was DX10 4AA that's all I know. ANd I have limited space on my single drive dude. Gotta ditch what I'm not using.

Fair Enough, SS. Quad-Sli ain't even working with CS anyways, so ... it's all academic, really.

BTW, I'm happy to announce my little article is done on p. 1 finally if anyone wants to check out the Quad-SLI vs. single Co-Op comparisons (along with some observations on the Co-Op vs. the Sandwich).

Hope y'all enjoy ... I put a LOT of time into this thing

Had to lower the OC's slightly after discovering that WH wasn't entirely stable ... noted in the original post...

JustTrollin · 07-06-09

so whats the bottom line??? double or single PCB??? that dumping heat into the case prob is a bit tricky eh???

brettjv · 07-06-09

Trollin, bottom-line, I like the co-op, it's cooler and quieter and OC's a bit more than the Sandwich, but it feels 'cheaper' and lacks the Volterra VRM. Quad-sli I feel doesn't have any real practical value when it comes to gaming, at least not at 1920x1200.

The 'extra' heat isn't causing my other temps to rise, at least not noticeably. Remember that the sandwich has a buncha vents on the side that dump heat in the case as well.

I'm throwing my sandwich up for sale, and if it goes in the next 27 days, I'm keeping the Co-Op primarily cause I like it's cool/quietness, and the extra OC is a nice little bonus.
