Hi,

I can only play BF4 on 1920x1080 on high-mid graphic settings without any lag. Which of my components is the bottleneck?
AMD FX-4300 (OC'd to 4.4GHz)
Sapphire Radeon R9 270X 2gb oc edition (OC'd to 1120MHz core clock with 1.244VDDC

I think it's your quad-core CPU holding you back.

I see a lot of people pairing a moderately OC'd FX 6300 with the R9 270 and getting good frames on High with some Ultra in BF4.

Bumping your CPU from FX 4300 to FX 6300 with a good cooler like a Hyper 212 EVO will allow 4.4-4.5GHz and support the R9 270 well. It's going to run around $150 total for that upgrade.

Your Sabretooth board is more than capable of handling a 6300. An FX 8320-8350 is also easily doable but cost a bit more and require...

There can be a number of sources for your concern which can impact your performance in direct and indirect ways. Memory. PSU. Bus (MB).

Based on these two options though - it seems the video card would be a potential culprit.

You should try to examine the rest of your system as well if this is a true concern - or simply live with what you have if it is a passing interest.

REally? Should I be able to run BF4 at ultra? :eek: My motherboard is a Sabertooth 990FX R2.0 AMD3+ platform. I have 2x 4GB Corsair Vengeance 1600MHz, that are OC'ed around 18xxMHz, with a 650W PSU. And what is a culprit? My english isnt so good. Im downloading 3DMark 11 atm, to see if my score is where it should be.

And regarding that im running the highest settings my system can run. What do you mean? My temps are very good, even the VRM's doesnt exceed 60c. Nothing get's above 60c.

So, if the FX4300 CPU is my bottleneck, will OC'ing it some more increase performance?

Your Sabretooth board is more than capable of handling a 6300. An FX 8320-8350 is also easily doable but cost a bit more and require better cooling. Also, adding a 2nd R9 270 later will run well as the 990FX chipsets will support 2 x PCIe GPUs @ x16.

Any upgrades will not happend, atleast not for some months (This rig is like 2 weeks old, lol)
But Ofc, i am still enjoying the game and so, playing it very much. But im obsessed in OC'ing, and I want a reason to do it, haha.

So, I do not need to OC my GPU more? Currently on 1120MHz core clock. Is my MB 4+1 board? (Sabertooth 990FX R2.0 AMD3+) And low latency DDR3, what does that mean? I have corsair Vengeance 1600MHz, but it's OC'ed to 1866MHz (CPU FSB way) Should I OC my RAM some more?

Or should I just increase my CPU multiplier and VCore abit to get some +fps in BF4?
Btw, I already got a Hyper Evo 212 installed! :D

EDIT -
Weird, when I ran 3DMark 11, it says i have 8 cores :s. Is my score where it should be?

3DMark Score7107 3DMarks
Graphics Score8609
Physics Score4611
Combined Score4750
Graphics Test 137.76 fps
Graphics Test 242.02 fps
Graphics Test 355.91 fps
Graphics Test 425.85 fps
Physics Test14.64 fps
Combined Test22.1 fps

Overclocking won't help too much here. It's not the speed of the CPU that's preventing you from playing on higher levels. It is the absence of the cores (based on AMD architecture), that is holding your system back.

The motherboard you have is a great motherboard for overclocking. It has a 8+2 power phase design and proper cooling. A bit overkill considering you only have a $100 CPU, but great board none the less. And no, you don't need to overclock RAM. AMD technically doesn't support frequencies above 1866.

Ouch... Now that sucks, lol.. If I OC my GPU some more, will it have no affect at all, because it's my CPU that is my bottleneck? I increased from 1120 to 1125MHz, and I got a increased FPS on average 0.3 on all graphic tests, haha. But my FPS on Combined Test decreased by 0.2. Does that mean anything, or could that be a windows program that ran at that time etc?

Btw, is 1.44v good for my OC setup on CPU? (From 3.8 to 4.42GHz) It havent crashed anytime, but I have only tested large FFT Prime95 for like 10minutes. But im playing BF4 very much, and it survives :p If I decide to increase it to 4.5GHz, should I increase my VCore if 1.44 is enough for my current setup?

Or can I decrease my Vcore abit? Give opinions! :)
