A warm hello, and a couple of questions! 8320 Current build

post #1 of 59
Thread Starter 
Hello guys,

First of all, I would like to say a big hello to all of you. I've been reading the forums for a really long time, but never actually registered. Now would probably be the time to join you smile.gif

I'd like to point out my build at start, and then ask a couple of questions.

CPU: FX8320 @ 4.5GHz (God knows how this works, you'll see later)
MB: Gigabyte 970A-DS3P
GPU: ATI R9 270X PowerColor PCS+
PSU: Thermaltake 630W Modular
Storage: Samsung EVO 850 250GB, Kingston V300 120GB, 1TB WD HDD
RAM: 8GB Silicon Power (one of the cheapest)
Case: A bit modded Raidmax Viper

Okay, so the main cooling of the CPU is the Cooler Master Nepton 240M. This guy does an excellent work at stock speeds @3.5GHz, it keeps the CPU at 35c MAX after half an hour of Intel Burn Test. I also have one CM SickleFlow 120mm on the side of the case blowing mostly onto the GPU, one on the front of the case blowing to the storage devices, and currently I dont have an exhaust fan since my radiator is mounted ON TOP of the case with pipes going through the whole where the exhaust fan used to be. Max CPU temps I'm getting @ 4.5GHz are ~58c.

Now, when I got this PC, it was a pre-built, sold buy a store PC for like 500 euros more than a year ago, without SSD's, stock cooling, etc, and parts are left from that, which I'm starting to change.

Now, about that 4.5GHz OC. Thing is, I'm getting that @ 1.45V and the PC does work and crashes once in 3 months (BSOD) and I know that's because of the VRMs. This board has 4+1 phases, though heatsinked, it's deffinitely not for OCing the 8320. Problems arise when I start prime or IBT, they can work for around 30 seconds and bam, BSOD or something. I've tried adding a fan to the heatsink of the VRM's to make sure that the crashes are from it, and it can make it survive for like 2-3 minutes of the test, and then I get a crash again.

It's really a shame how the temperatures of the CPU at stock 35c get to almost 60c when overclocking, I'm really sad that it's that much of a difference. But that's probably because of the high Vcore. Point me if I'm wrong, I'm still learning a lot about this.

Now guys, this PC is mostly used for gaming, some Blender rendering, using flash applications, web/desktop app development, some virtualization of mostly android devices... a bunch of stuff.

I come from Serbia, Europe, and we do have a variety of PC parts to get, probably not the best prices, and I'm starting to change things in this PC by a bit. Things that I'd change, and probably in this order:

1. Motherboard
2. Case (probably along the motherboard, saving a bunch of time and instantly getting a bigger boost since this case is small for cooling)
3. Getting a better PSU (800W+, this one works great but it's mostly for the part number 4)
4. Getting another R9 270X for Crossfire, OR maybe selling mine and getting a higher-end GPU

That's mostly it for now.

Now for the questions.

I'd like to know if it's a good investment in a new ~200$ AM3+ board at this time. Would it be better to change to the Intel platform because of less power consumption, heat, and a variety of i7's out there? Or it is worth to spend 200$ on a mobo and continue using a 8320 for now, getting a better CPU in 2-3 years?

If I pick to choose to get a new mobo, would Asus Sabertooth 990FX R2 fulfill my needs for safely and stably achieving the 4.5GHz overclock and give me the possibility of full-speed crossfire with the R9 270X's? I'm also looking into the Asus Crosshair V Formula-Z and wonder if it's worth the extra 50$ out here compared to the other board.

I also have a question about the PC cases, I'm mostly looking into Cooler Master ones, they're most common here. I've been looking into the HAF series and would like to know your oppinion on them, and should I get a full-size tower case or a mid-tower would suit my needs for the airflow with the 240mm radiator AIO and the GPUs in advance?

That's probably everything for now, I hope I didn't eat your nerves, and thanks in advance! smile.gif

Right now intel is way better, but I don't see it worth the extra money to switch right now. The FX chips are still good CPUs. The Asus Sabertooth is a awesome mobo. If you are only looking 4.5ghz then there are others and a little cheaper way to go.
Like GIGABYTE GA-990FXA-UD3, ASUS M5A99FX PRO R2.0, AsRock Fatal1ty 990FX Killer and AsRock 990FX Extreme6.
All these mobo and the Sabertooth you can easily 4.5ghz with.

^^ agree. You will need a better motherboard having a good power phase design in one of the features. Above motherboards are little costly but you Can get Gigabyte GA-970A-UD3P. This is cheap but very very good at overclocking.

Well I would listed that one too, but OP wanted 2 PCI-E running at X16. Only the 990FX mobos has that.

Hey guys,

Thanks for the quick replies.

Right now I'm so mad that I got a DS3P mobo instead of UD3P. The current price difference here is less than 10 bucks, and I was out of PC building at the time when I got this PC so I thought it would handle the 8320 easily, even read the reviews where it said the VRMs are heatsinked, etc... so I bought that built PC from a local store. A few months later I noticed I was REALLY wrong with getting that PC because of the mobo.

Aside from the regular UD3P I see that the local shop has the GA-990XA-UD3, which is around 110$. That's a real deal because of the xfire support, but I'm still considering the Sabertooth since I've learned not to spend low bucks on main parts. I might be able to stretch for it. Do you think it would last a couple years with the 8320 with a good performance, in lets say games?

Now, overclocking-wise, would the Sabertooth give me more room? I like their digital power control, and more usage of power than regular ones (at least from what they say), that provides less heat. I read a review on that mobo here: http://www.overclockersclub.com/reviews/asus_sabertooth990fx_r2_review/ and the guy reviewing it easily got the 8350 to 5.2GHz+. I saw a bunch of other videos online with people getting the 8350 on it to 5GHz which is amazing. I wonder if the 8320 would be able to get there? Don't wanna be greedy, but I would like to know if it could go as nearly as far as the 8350 smile.gif

Thanks!

Well I had 2 FX-8320 and a Sabertooth V1 and a V2. One hit 4.7ghz and the other hit 4.9ghz. If you are trying the hit 5.0ghz then go for a FX-8320E or FX-8370E with a Sabertooth. The E version are low voltage, switch means you have a little better chance of hitting 5.0ghz on less voltage and heat. The Sabertooth is one of the best mobo you can buy.
Here is a pic on a FX-8320 at 4.9ghz.


Remember hitting 5.0ghz on any FX chip is like playing the loto, meaning you may or may not hit 5.0ghz. Most FX 8 core chips stops around 4.7ghz without a custom water cooling setup.

Wow, very nice results there. You got it just by increasing the multiplier, not touching the bus? And was that with the Sabertooth?

I think I'll need to see whether it's worth getting Sabertooth, I LOVE all the options it has, but then again, if I'm to change the CPU also, that can make the whole new story where it might not be the best option.

I've tried disabling cores on my 8320, the max I can get is this: http://valid.canardpc.com/3l56kn - 4.83GHz with 2 cores enabled, stress tested and works, but that's the max I can get. Did that to test the best CPU options for playing World of tanks, since the game only uses one core - they got really bad optimization.

http://valid.canardpc.com/7m7y78 - this is what I'm running now.

If I'm able to get 4.5GHz ultra stable (at least) with the Sabertooth it's worth it. If it can push it to 4.7GHz, I'll love it. But my main goal is stability on 4.5GHz. After all, the 8320 is only as good as you overclockit, that's how I see it.

I did some GTA V benchmarking, at stock 3.5GHz i get this:
Code:
Frames Per Second (Higher is better) Min, Max, Avg
Pass 0, 25.654560, 53.472401, 45.111839
Pass 1, 36.277779, 127.875366, 50.194115
Pass 2, 31.807745, 127.528671, 54.880524
Pass 3, 28.311666, 99.436394, 75.771278
Pass 4, 24.511126, 126.350853, 58.431103

At 4.5GHz I get this:
Code:
Frames Per Second (Higher is better) Min, Max, Avg
Pass 0, 32.206593, 65.827400, 55.317070
Pass 1, 38.157284, 76.553413, 62.551014
Pass 2, 29.290785, 96.619080, 65.961037
Pass 3, 33.167397, 127.458626, 91.392670
Pass 4, 19.256472, 122.350952, 69.844093

Those are results with extra high textures and really push the CPU and the GPU to the bare limit. I get 10FPS more on average, but I'd really like this thing to be stable and able to pass the stress tests.
Do you think Sabertooth will be able to pull up a bit more? And do you think it's worth around 80$ more than a UD3P? I'm getting hot-headed about that military board and I dont like that smile.gif


I'm gonna do some more reading about those mobo's that I'm looking for and see what they offer, but I'd also like your guys oppinion about it.

700 watts is more then enough for the new system you want you dont really need 800 watts or more.

Yes it is with an Asus Sabertooth V2 and I had a Corsair H100 with AP-28 (On Full Speed) to cool it.
