2 gtx970's in SLI with horrible frame rate

kickingadog · Dec 6, 2014

so i installed my gigabyte gtx 970s today and im getting horrible framerates.

Far Cry 4 on all ultra is averaging 30-35 fps

battlefield 4 also averaging around 30-40 fps.

My old 760 was pretty much out performing them.

My SLI overlay says SLI is enabled and all of my GPU monitoring software detects 2 970s.

I would appreciate any feedback.

rig:
i5 3570k
2 gtx 970's SLI
EVGA NEX 750B power supply
8g DDR5 ram (2x4)
antec kuhler 620 liquid cooling CPU heatsink
1 SSD
1 5000RPM WD green HD

what abt single card performance?

run one card and report back

kickingadog · Dec 6, 2014

ive fixed the frame rate issue but now i get 130 frames in BF4 and around 80-90 in farcry 4. Thats what i should be getting with 1 card.

When i turn off SLI i get the EXACT same frame rate in both games.

kickingadog · Dec 6, 2014

maybe when i turn off SLI in the NVIDIA control panel, it doesnt actually turn it off? I've seen the frame rates other people have gotten and its near the same...

also i have one of these (not exact one) in my second GPU
I don't know if thats a problem since I don't know of any other way to have enough connectors for two GPUs

You can't get DDR5 RAM

Robertwhyte · Dec 8, 2014

simple question... but are you using an sli bridge? and is the 2nd GPU in the right PCI E lane?

blacksheep123 · Dec 8, 2014

i suggest you to uninstall the drivers

clean the leftover with DDU
then dwnload the latest drivers and install it

blacksheep123 :

Ik this is irrelevant but does your CPU bottleneck your GPU?

blacksheep123 · Dec 8, 2014

Mr_Venbeer :

at 3.5 stock clock it did bottleneck a little.. but after i reached an overclock of 3.9 the bottleneck was gone.... i keep it at 4.1 ..just in case

i have paired it with my friends r9 295x2 ... it was bottlenecking a lot.. but when i overclocked it to 4.5 .. it was gone..

fx processors are great overclockers

Who the fuck told you s single 970 gets 130 frames in bf4 and 90 frames in farcry 4??? Were you joking? ..................

I'm running 2x 7970 ghz vapor-x @ 1200/6100 they pull in graphics scores of 24,000+ on 3dmark11, my i5-4670k is running @ 4.8 and id be lucky to get those framerates at ultra settings 1080p, if you indeed are, it seems both 970's are working very well...

I'll set all my Gaming Rigs on fire before I'd put an AMD/ATI card in them...

bishopi5 · Dec 10, 2014

Nice advice. Fool.

MaxxOmega :

set it on fire then
fan boy..

Only wish I had a better motherboard to overclock my 8320

yeah ,a good quality motherboard is the key... for an 8 core, you will need a proper 6 or 8 phase vrm atleast

Mr_Venbeer · Dec 12, 2014

Well I can OC this to 4.0ghz if I had heatsink or cooling on my VRM's. Could stick a fan on top

blacksheep123 · Dec 12, 2014

Mr_Venbeer :

you should be careful.. that mobo is solid , dont get me wrong but the vrm doesnt have a heatsink.... not safe for an 8 core...you will risk burning the mobo...

you could push a 4 core or maybe if lucky a 6 core

kickingadog · Dec 12, 2014

Ok, so I have noticed in almost all of my games my CPU usage is always in the area of 85-98%. When it jumps up to the 90s is when i've noticed the lag spikes and the stuttering. I have an i5 3570k Ivy Bridge OC'd at 44MHz. Could the issue be my Ivy Bridge is having trouble working with my two gtx 970s in SLI?

its exactly not the case.. to be honest nvidia have always had optimisation and instability issues with WOW ... more on the sli

there is very little you can do... you can google for solutons if you like

Mr_Venbeer · Dec 12, 2014

blacksheep123 :

Yeah. The ASRock 970 Extreme 3 is the same board just has VRM heatsinks. People with that board can oc this cpu to 4.0Ghz, others with mine put fans on top of the vrms and can also oc to 4.0Ghz. Do they sell VRM heatsinks like the ones that come with aftermarket VGA coolers? The individual ones?

blacksheep123 · Dec 12, 2014

Mr_Venbeer :

there are tiny differences.. like digi power vrm for better overclocking

anyways you can look into ebay
http://www.ebay.com/bhp/mosfet-heatsink

or amazon
http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Delectronics&field-keywords=MOSFET%20Heatsink

copper is always good... remember that mosfet cooling is passive so you should have good case airflow

Mr_Venbeer · Dec 12, 2014

Oh cool thanks. Will these fit on my VRM's though?
EDIT: Actually don't worry about it. I don't need to OC this any further anyways. Thanks though.

blacksheep123 · Dec 12, 2014

Mr_Venbeer :

they should..
the measurements of the die area are usualy mentioned anyways so you can check that out

Any ideas why on a game like Crysis 3 my CPU sits at 96% and my GPU sits at 50%?
