Hi all am new to the board so l'll say hallo first and now ask for HELP!!! >:(

so the story go's l went to i40 man it was good,so while l was there l saw 2x gtx 460 zotac's 1024 gb crad's man they're nice so l got two,well it's not went well.

my pc is

cpu-Q6700 stock 2.6ghz clocked to 3.3 ghz 775 intel scoket
ram-6 gb crossair 1600 mhz
MB- asus striker 2 ex
hdd-1tb WD 7200 rpm
psu-1200 watts antec
gpu- 2x gtx 460's sli

well here's my problem when l have one gtx 460 in l get a good fps in aion/dawn 2/mw2/and 3d mark benchmarking tool

aion 90 to 70
dawn 85 to 39
mw around 90
3d mark from 140 to 29

so when l sli it l get the same result's but shared with the card's l don't get any improvement at all when l sli l've e-mail zotac and here's what they said
"The "Q6700" processor may be a bottleneck, considering the extremely high performance of the new generation GTX460 display card".

is it really my cpu cos my problem if so what should l do or is it something else l can fix am at a loss.

Not sure what the issue is, but I do know they are feeding you crap, your CPU is fine.
This is one of the reason's I think it's better to go fast single GPU rather than SLI/CF.

Check both cards are working properly by testing them both separately.

Edit:
You may be better off returning one of the cards as you seem happy with the FPS of a single card.

Erm...actually before you tell the OP the CPU is not bottlenecking the cards, have you actually see reviews/test results that says that?

Take Crysis for example, a Q6600 at 3.7GHz bottleneck a 5870 in Crysis, because the game only uses two cores. Look at the results of Q6600 at 3.7GHz vs the i5 750 at 4.15GHz in the following:
http://www.bit-tech.net/hardware/cpus/2010/03/03/overclocking-intel-core-i3-530/8
And if you look at the E8400 at 4.25GHz, it deliver higher frame rate than the Q6600 at 3.7GHz because of it's higher clock speed.

Now I'm not saying a GTX460 1GB is as fast as a 5870, but we all know that a heavily overclock GTX460 1GB (i.e. 850MHz+) sit somewhere between the 5850 and 5870. So imagine the Q6700 3.3GHz as a pair of of E6600 at 3.3GHz, I'm fairly confident to say that if the clock speed can be pushed higher, he will definitely get extra frame rate from the GTX460s, considering a 3.3GHz E6600 can hold back a single GTX460 1GB.

But to be honest, I think an overclocked Q6600/Q6700 (expecially one that's closer to the 3.0GHz side than 4.0GHz side) is more suited for using with a single GTX480 than a pair of GTX460SLI...mainly base on the fact that most socket 775 SLI boards are poor overclockers for the CPUs (hard to push Q6600 further than 3.2-3.3GHz)...I wouldn't be surprised if the GTX460SLI here is not much faster than a single GTX480; and would be slower if comparing to overclocked i7, and with a pair of full x16 lanes vs pair of x8 lanes which could see 1-2% less speed from each of the two GTX460. A Q6600/Q6700 overclocked to 3.7GHz is only around as fast as stock speed 2.66GHz i5 750/i7 920.

I Would expect to see a large increase in performance. A 3.3GHZ Q6600 still has a hell of a lot of grunt.

Do your self a favour and get the single fastest card you can. Multi GPU's are not worth picking over a faster card.
 
Marine, the OP is saying he is literally not seeing any improvement in FPS with SLI. There is almost certainly an issue somewhere other than the CPU he is using.
His Q6700 should allow a good boost in FPS (not strictly performance), obviously an i7 would run faster than his Q6700 but he isn't getting anything and he should be...
 
MW2 is capped at 90fps.
3D Marks if its 06 is heavily CPU capped - but if its vantage you should see a decent score boost.

Can't speak for the others.
 
Hi and welcome to the forum.

Are you getting any increase in frame rate at all? As it sounds like SLI isnt actually working. Have you actually enabled SLI in the control panel and confirmed it is enabled with gpuz software?

Which driver set are you running please? As mentioned, resolution and monitor setup would be great to know :-)

I was not talking about the SLI issue, I was refering specific to the point of CPU bottleneck you bought up. But you are right about the problem that the OP is encountering...it does not seem to be CPU related.

I totally agree with that. However, I recalled seeing benchmark results for 5970 with the Q6600 bench at stock speed 2.4GHz, 2.8GHz, 3.2GHz, 3.6GHz and the frame rate increase throughout the way up. While GTX460SLI is not the same as a 5970, I would think logically, the frame rate will be higher for the GTX460SLI with a Q6600/Q6700 at 3.6GHz than at 3.3GHz. Q6600/Q6700 are great, but even greater if they can be overclocked further.

Also the whole point of people getting GTX460SLI and because they want the extra speed over a single GTX480. But with Q6700 only at 3.3GHz, I'm not sure how much of those extra speed over a GTX480 the OP would actually be seeing.

After seeing all these people with SLI/Crossfire issues, single GPU does seem to be the way to go.

hi and thx for ur reply's

am gonna up upload two screenie's one with one gpu and one sli'ed

screen res is 1920x1080
driver's 258.96
monitor is a 23" lg flatron w2361v
control panel see's both card's same bios same driver's same clock same everything sli is turned on and device manger see's both card's as well.

2x gpu


1 x gpu

It's like sli isn't working at all.
Do the following.
Uninstall drivers normally i.e. no driver sweeper nonsense
Restart
Install latest drivers again
Restart
Restart again.

Report back if it works...
 
Did you say you have enabled sli in the control panel under set sli configuration to "maximise 3d performance"? and also turn on the visual sli indicator under 3d settings.
 
update l just installed window's 7 l was runing vista same issue but l get alittle more fps only talking 2 to 3 can anyone help me out please don;t know if l should send them back as it's pointless have two thats not doing anything.
