Amd FX-8350 - Few problems

Dapunisher6666 · Sep 21, 2013

Hi, first of all, here are my specs:

Mobo: ASRock 990FX extreme 3 (Bios v1.50)
PSU: Corsair TX 750M (750W)
CPU: AMD FX-8350 stock clock
Cooler: CoolerMaster 212 EVO
RAM: 8GB DDR3 1600MHz kit (2x4GB, Dual)
GPU: EVGA GTX 770 FTW 4GB w/ ACX Cooler
HDD: WDC WD20EARX-00PASB0 ATA Device (2000 GB, SATA-III) (Caviar green, 5400RPM 2TB)
OS: Windows 7 64-bit Professional

Now, let me explain my first problem. A week ago, I had an AMD FX-6200 @3.8GHz on the same motherboard (extreme 3), stock fan, which was doing pretty well. Wasn't that noisy, temperatures were fine, but I thought and found out that this CPU would bottleneck my GPU, so I switched to a 8350. At first, I installed it with the stock cooler, but I had a big annoying problem: at idle, the fan RPM was always over 3500 and under load over 5000RPM, but the CPU temperatures were never over 50°C. Annoyed by the noisy sound of 3500+ RPM all the time, I decided to buy the CM 212 EVO CPU cooler today and installed it. Surprise, I don't hear the RPM anymore since it's now around 1250 to 1400 RPM idle or under load BUT I get over 50°C under load (near 60°C) and around 35 idle. Basically, my problem is that the temperatures should be lower since it's a good aftermarket cooler and shouldn't be as noisy as the stock one, right?

Second problem, which I think is related to my new CPU: In Battlefield 3, every few minutes (4-5 mins), I get a huge FPS drop from 60 (with V-Sync) to 20. The thing is, that never happened with my FX 6200 but it used to stutter a bit, due to bottleneck (reason why I went from 6200 to 8350).

Finally, this last problem might be related to the 2 others above: If I go on ASRock's website and look at CPU's support list for my mobo, (http://www.asrock.com/mb/AMD/990FX%20Extreme3/index.asp?cat=CPU)
I cannot find the FX 8350 but my CPU is detected in my bios and in Windows 7. Also, some people got the same motherboard and the same CPU (even OC'ed) and don't appear to have any problem.

If anyone got a solution, I could really use some help, I am lost.

You might be confusing the coretemp and CPU temp for each other. I would upgrade to a new motherboard BTW, and perhaps get an SSD..

I don't think it's a bottleneck issue. I have a GTX 770 and an FX-6300, and Battlefield 3 is probably one of my most well run games. It has always been at a constant 60 and only during the most intense explosions do I ever go down to like 50, even on 64 player servers. Then again, I've always played BF3 with an overclocked FX-6300 at 4.2 GHz, and since Battlefield 3 doesn't use 8 cores (I really doubt it would, anyway) the game would basically utilize both our CPUs in the same way, except I have a 200 MHz clock over you. Still, that shouldn't account for the stuttering. My only guess is (and this is quite a stretch) that since you're using stock clock and stock BIOS settings for that CPU, your CPU goes through frequency fluctuation, a feature that occurs where your CPU automatically underclocks in order to save power. Most of the time this doesn't effect games because it's only supposed to underclock when the current clock rate isn't necessary for the task, but I suppose it's possible that it could be erroneous at some points. When people overclock, most of us turn off these options for frequency fluctuation, so again, this is quite a stretch, but perhaps that's the reason?

For your cooler, maybe you didn't clean off your CPU properly? Only use isopropyl >99% alcohol to clean it. That could account for why the temps are so high, as under load I don't get higher than 53 with my Hyper 212 Evo and an overclocked CPU. Also, on the website the FX-8300 is listed as being supported. The FX-8350 is just an overclocked FX-8300, but other than that they're the exact same so I don't think that's the issue.

The last thing is, it's always possible that you have a bad board or a defective CPU. I have my own troubles with my FX-6300. On BF3 it's a rarity for me to go under 60 fps, but for Crysis 1 I'm constantly shifting anywhere from 30 - 60. Meanwhile, other people I know play Crysis 1 with an FX-6300 and an even weaker GPU and maintain frame rates that never even fall below 60. It's really quite a mess, and I can't seem to figure out where these issues come from.

Thanks for the fast answers so far guys! Could it be my HDD bottlenecking? And by the way, many people told me to look only at core temps, which are around 20 to 30°C idle and goes up to 45 in many games, except for BF3 which drives the temps up to near 60. But the CPU temp itself goes up to 69, is it normal? My CPU has been cleaned before setting the cooler. Also, some people said that the ASRock extreme 3 wasn't very good for overclocking. Since the FX-8350 already has a high clock speed, could the motherboard not be powerful enough to handle the CPU?

The Q6660 Inside · Sep 21, 2013

Dapunisher6666 :

Perhaps the combined issue between both the motherboard and hardrive create some sort of "bottleneck" for the 8350, BF3 takes advantage of up to 6 cores, yknow.

Deus Gladiorum · Sep 21, 2013

Dapunisher6666 :

I'd say it's really likely a motherboard problem. These days, everyone's HDD is a bottleneck, because there is no HDD that can feed data as fast much as the CPU requests. Of course, in the case of BF3 the HDD only matters for as long as the loading screen lasts. During a loading screen, I believe what happens is that data is loaded from the hard drive and placed into RAM. Once all the necessary data has been placed into RAM, the HDD's job is finished, and the level begins where the CPU can access data stored in RAM and process it as necessary, as well as create new data to store in RAM when necessary. Beyond that, the HDD shouldn't create a noticeable bottleneck. The only time it should create a noticeable bottleneck is in games without loading screens (usually large, open world games) that require a new set of chunks to be loaded directly from the HDD after entering a new area. So yeah, if my theory holds true then the issue should pretty much only be a motherboard problem. If you have an extra motherboard around of the same socket, or a very generous and willing friend, you could try swapping out motherboards to see.

cmi86 · Sep 21, 2013

have you ever monitored the cpu speed while gaming ?? I'd be willing to bet your VRM's on the motherboard are overheating and throttling back every few minutes to cool down. Happens on a lot of 970 boards with 4+1 phase systems rung high power cpu's when they are under a high load for long periods of time. Id try running rightmark cpu utility while gaming and it will tell you all of your utilizations, temps and frequencies across all 8 cores.

The Q6660 Inside · Sep 21, 2013

cmi86 :

The 990FX Extreme3 is a 4+1 phase board, so that might be the issue.

Dapunisher6666 · Sep 22, 2013

Would the ASRock 990FX Extreme 4 be a better motherboard? I don't think I will be able to get my money back so I might need to exchange it for another one. If I can get my money back, I would definitely go for Asus Sabertooth 990FX R2.0 tho.

The Q6660 Inside · Sep 22, 2013

Dapunisher6666 :

Go for the ASUS M5A99FX PRO R2.0 if you are short on $, Sabertooth R2.0 if you are not.

Dapunisher6666 · Sep 22, 2013

Is the ASUS M5A99FX EVO R2.0 similar to the PRO one? Because there's only this board where I usually shop, can't find the PRO one.

The Q6660 Inside · Sep 22, 2013

Dapunisher6666 :

Pretty much the same, although I would go for this. Don't forget to backup windows and apply other steps should you have an OEM version. http://www.newegg.com/Product/Product.aspx?Item=N82E16813131851

cmi86 · Sep 22, 2013

its basically the same board. only difference is pro supports full x16 bandwidth on both pci-e slots for crossfire.

usbgtx550 · Sep 22, 2013

I have the pro for my 8320 and it is a rather nice board. If you don't plan on doing a crossfire or sli setup in the future the evo would be just fine.
And for reference, at stock clocks my 8320 doesn't get much higher than 40C with a hyper 212.

Just asking a question that hasn't been asked here...

You did re-install windows after swapping CPUs right? Because that could easily be the issue if you didn't...

Dapunisher6666 · Sep 22, 2013

No I didn't, but that shouldn't be the problem I think. I heard you do need to re-install OS only when changing motherboard. (Because of new chipset)

8350rocks · Sep 22, 2013

Dapunisher6666 :

No, you need to re-install Windows when you swap MB or CPU. Though, they may have some sort of patcher now for that; however, I suspect that's the reason your CPU doesn't show in BIOS and is the entire reason I asked.

Try a clean install of Windows and see if your issues don't evaporate. (By clean, I mean backup programs/format HDD/reinstall from scratch)

Dapunisher6666 · Sep 22, 2013

Who said my CPU didn't show in BIOS? It does, lol.

8350rocks · Sep 22, 2013

Dapunisher6666 :

Sorry, I misread where you said it was detected in BIOS...thought you said it wasn't.

Either way, I would do a fresh install...

iam2thecrowe · Sep 23, 2013

the cpu is not on the supported list, that is one problem. even if others have it working it may just be that they got lucky. If it were me, id hard deset the bios with the reset jumper/switch to get bios settings cleared and back to default. then go into bios and set it up the way you want it. And as has been said, a clean windows install often fixes some strange problems.

cmi86 · Sep 23, 2013

usbgtx550 :

How so ? I use the Pro 2.0 and I was always under the impression the Evo had the same exact power systems and was basically the exact same board as the pro (minus full x16 bandwidth on 2 cards) Which would make it basically as good for OC as the Pro 2.0
