Bottle neck? MSI HD7870oc new BenQ= FPS drop

post #1 of 14
Thread Starter 
First post on here. I upgraded from a 5770 to a 7870 oc back in like Aug. for the most part seemed to be an upgrade, but not like I thought. I mainly play World of Tanks some BF4 as well. I did see that I could turn the setting up on WOT more than with 5770. here is my issue. This past Sunday I bought a new BenQ 24" 1080p LCD gaming monitor, it looks awesome!! Thing is my FPS took a dump big time! My old monitor is an Acer 23" 720 LCD. When I play on the old Acer my fps avg 20-30 frames higher than the BenQ. I know resolution will hurt fps, but that much? I've tried cranking up the clocks on the card and that really doesn't do squat.
I also dual this card as well. WOT doesn't support crossfire but BF4 does. On BF4 I'm only getting round 33fps with both cards on ultra, 38 if I dumb it down?? Here is my rig below.

FX-8350 OC 4.3
ASRock 990FX Extreme4
Dual MSI HD 7870oc
16 Gig DDR3 1333Mhz Blastix
CoolMaster 850w mod
Haf 912 case 2x 200mm fans 2x 120mm fans
750 GB HHD
Win 7 64-bit

I know this set up should rock, but it doesn't seem to be that. On 3DMark11, 1 card nets 7661 both cards net 11363. I know that's a big increase with the 2nd card. I just wonder why the fps on WOT is tanking so bad with just the monitor swap? If I crank the clock up(1250 core 1350 shader) on the card, I get a driver fail message. Back them down(1150 core 1265 shader) it runs. Still low FPS, but works.

So question is A) Is it this card just can't handle it? B) Am I doing something wrong on the OC? C) Should I roll these over to my kids computer and get a different card?

Sorry if I didn't word this correctly, but I'm trying to learn to build these things. This is my 1st build so I know I have tons to learn. Thanks in advance ya'll.

When you oc the card you need to increase the power limit on msi afterburner/catalyst,btw which is the vram/gpu usage on th game you had bad performance?

Check to make sure your video driver is not overriding in-game AA and texture quality settings, or "enhancing" them. Set all sliders to "performance" for now.

Check to make sure your CPU overclock is working as expected. A thermal limit can force these chips to scale back speeds.
What method did you use to achieve the overclock? What voltage?
What cooling solution on the FX-8350?

Make sure windows isn't throttling back the CPU with power saving features.

How are all those case fans configured?

In BF4 I would expect that you should get around 30FPS minimums on a single GPU, and around 60FPS minimums on a pair (with appropriate AA settings), so something seems out of whack to me.

PontiacGTX--- I increased the voltage on the slider bar in Afterburner to +10. I know you have to increase the voltage when increase the. I just hope that's how you do it. Like I said, I'm just getting into building so lots to learn. World of Tanks is where I get frame drop. Before the new monitor 60s-80s+ FPS, new BenQ and the forest maps & maps with lots of detail it will tank as low as 26fps. I turn 1 card off as I know WOT doesn't support Crossfire.


Mdocod---- I don't know how to check and see if the drivers are doing that, nor do I know the sliders your speaking of. Is it the sliders in the CCC?

I over clocked the CPU by turning on the Boost feature on my Asrock 990FX board. I guess it OC the processor safely? I turned of the Quite n Cool in BIOS like I have read. I I have a 6 pipe aftermarket cooler with 1 120mm pusher fan.
I will google the power savings in Windows, but I pretty sure I got it set the "screw the ozone & throw some more coal in there!".

I have a 200mm on intake in the front of the case. The other 200mm is exhausting the top of the case over the cpu. One 120mm exhausting the rear as normal with the cpu cooler pointed towards it. The last 120mm is on intake on the side of the case in line with the gpu's. I will replace the 120mm on the side with a better 140mm. found out the 120mm is only moving like 40cfm. The 140mm on order moves 124.6cfm.

On BF4 I just go to setting and move from high to ultra, I adjust nothing else. I know what AA is and kinda understand that it can effect fps.

Thanks to both you fellas!

Voltage or power limit slide bar?

Which are the gpu and vram load during the low fps?

PontaicGTX-- Looks as though its the power limit slide. For some reason I cant do anything with the voltage slide. About the gpu load, CCC says 87% and up. I have seen it hit 99% many times now with the new BenQ monitor. I don't know how to check the vram?? I just check my power settings in windows and I was on balanced. I'm now on performance!

gpuz or MSI afterburner shows it

MSI Afterburner. I googled it. I can adjust now, but not much. stock was1.219 I went 1.229 core clock 1155 shader 1305 power limit +9. gonna try that.
post #9 of 14
Put power limit on 15 to 25% (i am not too sure about how much % usa bcuz I have a hd 7870ghz and drivers says up to 50%,lol)and see if that improves the fps/increases the gpu usage.also check the vram usage(for being sure that you arent running out of vram

15% and the fans spool up to take off speed and the screen goes black! HA ha! Looks like 12% is the max b4 black out! upped the core clock to 1180 voltage to 1.236. no increase in fps!!?? Startin to think it's a driver issue or card just don't have enough balls to run the BenQ GW2450 24" LCD 1080p! EVGA GeForce GTX 770 here I come!
