I upgraded from an AMD Phenom II x4 965 earlier this month, hoping to get better frame rate in games that fight my system. I got a little bit of extra fps from the FX 6300, but the problem is at random intervals my frame rate will drop hard, from its hovering peak of around 90-120 to just below 30 and go back up to its normal. I've turned off power save settings in the BIOS to hopefully fix the issue but nothing has worked. Idle temp for the CPU is around 40C while load, this includes during the spikes, never goes over 60C. I notice that if I watch CPU-Z while playing, that sometimes the clock speed will boost itself to 3.8ghz. I don't know if it is related, my concentration is too bad to tell. Could that be what's causing it? If so how would I be able to disable this "turbo" feature. (Please don't recommend that I upgrade to an 8350 or some kind of upgrade, I can't even afford a soda right now)
My guess would be crappy motherboard. I had a similar problem with the FX-6300 on a Gigabyte 78lmt-usb3. Even at stock clocks, my cpu clock speed dipped will below the base clock, much less any overclock, and temps never rose above 55c under stress test. I chalked it up to shitty/overheating VRM.
Turbo likely isn't causing the issue, but can be disabled in the BIOS.
Would that happen with a newer, lower TDP CPU? Specs say the FX 6300 and the 965 are 125w CPUs but elsewhere it says that the FX 6300 actually uses less power. I didn't have these lag spikes with the 965.
those frequancy boosts is normal, its also normal, that the cpu on idle will clock back to arround 1.4Ghz, if you have cool n quiet enabled. 3.8 ish ghz is the turbo clock of the cpu. So basicly its working fine so far. i suppose.
I dont think that your fps drops is caused by those speeds boosts. Still if you go into the bios, go to cpu settings, and disable cool n quiet. This will keep the cpu on atleast its stock 3.5Ghz, and wont drop lower normaly, Unless your board is throttling, But i dont expect that with a FX6300.
Also download the latest Nvidia drivers.
About the fps drops in particular, this could be driver related, But it could also be a bottleneck. Are we talking about single or multiplayer? and which resolution?
Also 90 - 120 fps on 1080p maxed out on a GTX760 OC sounds a bit unrealistic to me.
Ya, BF4 120 FPS on that? I doubt it. I get about 150 but then again im using 2 970s. My brother uses a water cooled r9 290 and he gets about 70-90fps on BF4 with an 8350.
In multiplayer, and I keep my settings at all low besides Texture Quality and Mesh Quality, but I've run it with those settings at their lowest with no improvement. I'm starting to think it is probably my motherboard. When I bought it, everything said it was "FX 8 core ready" but just before I bought my FX 6300 I had to update the BIOS so that it would support AM3+ CPUs, as it previously could only use AM3. The original build of my rig i built in April 2012 with the only difference to what it is now is CPU and GPU. If it is just the motherboard I may just wait until I can afford it and buy a new motherboard and powersupply, 500w is pushing it.
I believe I have discovered the issue. CPU-Z shows that my RAM is only running at 400mhz. Since it is 1600mhz running in dual channel mode shouldn't it be at 800mhz? Looking in the BIOS to see what it says there.
