Hmm I've got to find away to push my CPU a little harder it seems. I know a 7900GTX Sli setup beats a 7950GX2, as a 7950GX2 is closer to a 7950GT sli

@up Two things :
1) I OC'ed 7900 GX2 to 600/700MHz, so it will be faster than 7950 GT SLI.
BTW stock clocks for my card are 100MHz lower than this (ie. 500/600 [GPU/VRAM]).
2) 7900/7950 GX2 or 7900 GTX SLI WILL all be bottlenecked in this benchmark (by either of our CPU's).
BUT is this bottleneck enough for ~10% GPU speed difference to not matter ?
I think it is.

just you wait, im going to see what i can coax out of my system. I gained 5FPS by just upping the ram speed 😜

One question : How good is your CPU/RAM cooling ?

its fine the board is the issue, i can't change voltage above 1.4 which is stock

Did U tried disabling CnQ technology ?
I don't think there is a MB manufacturer smart enough to enable SLI and dumb enough to disable Vcore control in BIOS 😁

ASUS did it with this one, but the M2N-E SLI was an entry level SLI board for cheap, I remember buying one back in 2006 for $87 brand new. It's an AM2 Nforce4 SLI chipset instead of normal AM2 with NForce 560, 570, or 590 SLI

I could pin mod it to 1.5V, my cooler is an Artic Freezer A11 with a 150W cooling capacity.

that or since I have crash free bios I might just see If i can open up voltage options on this board with some bios modifications.

Nice scores!

I have updated the list, I will be less active during the summer but if I find the time I will rebench some A64 systems and my Pentium D 965 EE. At the moment everything is in boxes as I'm renovating a bit.

I will try to update the list at least once a week in any case, if there are any new scores that is. Should I forget to update the list just send me a PM and I will do it ASAP.

@candle_86 : Great job with 200FPS+
BUT would U like to try something harder ?
Replace 79000 GTX SLI with GTX 960, and let's see what OC'ed AM2's Athlon 64 x2 can do against this : LINK 😉
Good luck 😁

I have not bought the new doom, and will not. I own Doom3 because I wanted to try it, and I found it lacking in gameplay, plot and enjoyment. I want a game with a plot, a story line, and wide open spaces, a corridor shooter agasint hordes of enemies just doens't interest me. Now if you want to see what my 960 can do on doom 3 with my AM2 sure.

I love this thread and always look forward to new posts - it's so fiendishly simple...

@Standard Def Steve I almost on par with your C2D E6600 3GHz score (228,5FPS) 😀

I was still benching on a very slow nForce 650i board with DDR2-667 memory back then.

I mean, look at my 3.08GHz Core Duo T2600--its performance is roughly the same as the 3GHz C2D, which shouldn't be the case. Core 2 Duo is typically around 15% faster than Core Duo clock for clock. However, the T2600 was benched on a i975 chipset board, which propelled its performance to the level of the 3GHz E6600 on the slow nForce board.

I'm sure if I put the 3GHz E6600 on my much faster P45 board, it would perform much better. I benched my Q6700 on both motherboards
Q6700 @ 3.33GHz on nForce 650i = 265fps
Q6700 @ 4GHz on P45 = 358fps

Around 100 fps faster from a mere 667Mhz increase in clock speed! It's clearly more than just raw clock speed that's boosting performance there. The nForce 650 is just a dog slow chipset. 😀

That is awesome!

I'm very curious if your CPU can fully max out a single 7900GTX in Doom 3. What's your score with SLI disabled at stock GPU clocks?

A single 640MB 8800GTS gets 290 fps under Win7 with a 4.5GHz i7 driving it. It's completely GPU bottlenecked, because adding a second GPU for SLI pretty much doubles the frame rate (568.5fps).

It'd be interesting to see how a fully maxed out 7900GTX compares to the first-gen 8800GTS. I wonder if there's a difference between XP and 7 in completely GPU bound scenarios.

ill check it and see how its loading later tonight maybe

So it seems I'm not maxing out my 7900GTX SLI at 10x7 then again i tested it and at 12x10 i get identical FPS so I guess i knew 🤣

I see you got some more speed out of the Pentium D XE 965! 😀

I moved your system up in the "everything goes" list, your old score in that list must have been with Doom 3 v1.3 as a 65 FPS gain is just too awesome to have been just video driver, video card OC and 100 MHz CPU speed. 😀

A 5 GHz "fully tweaked" dual core Netburst CPU performing on the same level as a 3GHz Core 2 Duo running on a slow motherboard is just about how I imagined Netburst would scale with a fast video card.

Thanks for testing that! 😀

You've gotta be close to maxing out a single card, since you gain 11 fps from enabling SLI. On my Opteron, adding a second 8800GTS didn't improve performance at all; in fact I lost 1.4 fps.
