Just bought the Amd FX8350 and Asus Crosshair V Formula-Z. Just want to ask the board is with 8pin +12v and 4pin +12v, my psu got only 8pin so then 4pin +12v no power also can boot the board right?

I don't want to be rude, but the manual is there for a reason. In case you were lazy, its in page 1-43, yes I have downloaded the manual for that motherboard and read it.

Its just a general rule of thumb, no matter how expert you are in computer, you must read the manual that comes with hardware because sometime common question or tips and tricks is inside there already.

I've read it so many times but the manual just say
CODE
Do not forget to connect the 4-pin/8-pin EATX12V power plug. Otherwise, the system will not noot
Have u try this board ? Need all 4 and 8 pin to power up?
*
No I havent. Its only the eatx12v_1 is the primary one. As long as you plug it there board should work. But I guess even the 4pin eatx_2 would work.

They don't need to disable too much on FX 4xxx series CPU. It won't be a viable upgrade for anyone on Phenom II. They still don't reach here though, both the FX 6300 and FX 4300.

QUOTE(WiLeKiyO @ Dec 8 2012, 10:51 PM)
Anyone could suggest a RM400 below AMD CPU to pair with HD7850 ? Currently all suggest go with Intel 3220 which no overclocking feature.

Should I go with FX-4100 ? According to some review it will causes bottleneck to HD7850 unless overclock it.
*

Bottleneck always occur in any system, thing is whether it is big or small.

FX-4100 would be good, heck even my Phenom II X4 runs great with HD 7850. Its just people underestimate AMD CPU just because it eats more power than Intel CPU and they better at benchmarks, it doesn't mean it wasn't fast, its just not as fast that's all. But on the upside AMD could do overclocking, and a lot more fun with tweaking. Plus it it is supported for future CPU revisions. Going LGA1155 means pretty much buying a soon-to-be replaced with Haswell on LGA1150.

If you wanted to, you could opt for AMD A8 5600K FM2 with Gigabyte GA-F2A85XM-D3H for RM 429 and RM299 respectively.

Yikes. I'm very disappointed with AMD after seeing this.  sad.gif

Looks like I'm going to get i5 3570 instead after looking at this.

Do you suggest I wait for AMD to release anything?
*
Disappointed of what? The framerate might be lower but does that mean the game is unplayable? Of course not. The game he showed is not the game you want to play either so why worry? People just over exaggerate with graph to make AMD looks bad, truth is gameplay wise it still smooth. The game you wanted to play aren't that demanding either.

EDIT: The graph on anandtech shows the extreme CPU bottleneck, why? Because it uses low detail AND 1024x768 resolution! Nobody play games with 15 inch CRT resolution anymore. At higher resolution with same graphic card the performance should equal out because the bottleneck is shifted to GPU. Dont fall to the same trap salesperson at shop do to you

So, APUs are for movie and basic gaming? Will games like Sim City 5 and Sims 3 run on them?
So, the A10 will be able to handle Sim City 5 and Sims 3? Even FIFA too?

So all the statistics and graphs are just perception issues? So, as the resolution increases, the game will run smoother? Is that what you're saying?  rclxub.gif
*
The games you mentioned is far from demanding, you can Google to get an answer to that. Thing is, for your budget its better to go for FX + discrete GPU

It's not perception issue, that test are designed to do at low resolution and low detail which lead to CPU bottleneck. The performance won't become better at higher resolution at higher detail, but the performance difference between CPU will become less as the load shifted from CPU to GPU limited.

If you still doubt what AMD capable of, look here for AMD Trinity A6 5400K performance with Skyrim, Battlefield 3 and Mafia II which is a far more demanding titles than your mentioned games above at fullHD resolution, does that looks jerky to you? It's not even top of the line APU to begin with.

Hmm... So it does seem that the APUs are not bad, for their prices.

Any reason why you suggest that proceed with FX + GC instead of A10?

How bout running an APU + GC? Would that be a good choice too?
*
There is nothing wrong going for A10 + discrete GPU, it's just what's the point of buying CPU with integrated GPU when you use a discrete one, pointless isn't it? You get better performance from getting better performing CPU with discrete cards. AMD APU in Malaysia is expensive to be honest, for the price of A10 5800K (RM499) you can get AMD FX 6200 which gives one more module, or two more cores totaling six core instead of four in A10, or for RM60 more you can get full on FX 8320 (RM559) with 4 module and 8 cores.

I see what you mean now.

Its financially more practical to get the FX series.

Thanks for the advice!  icon_rolleyes.gif `

i got a problem.. my windows wont boot now. it keeps looping on the loading screen..
is there any ways to fix this without reinstalling my windows? hmm.gif

You can do this, I tried this before and it worked

1. Changed IDE driver to generic in Device Manager (on old system)
2. Uninstalled relevant drivers
3. Removed all relevant devices from Device Manager
4. Safe boot
5. Driver cleaner
6. Change to new system
7. Boot
8. Install proper drivers (some were auto found, others installed manually)
9. Updated drivers to latest version

Is 50 °C during idle considered normal?

I'm using hyper tx3 evo and during load it goes up to 70 °C...  unsure.gif

I don't know much about Trinity APU, but that is quite high. Maximum temperature is 74C. Have you enabled CnQ in BIOS, and other power saving as well? Check your Windows Power Options as well. If that fails use AMD PSCheck to control its P-States and undervolt



EDIT: For crying out loud guys, please stop quoting the pictures. No one wanted to see that continuously in one page shakehead.gif

my room temperature is around 27 celcius. not air-contidioned room.

I am using a 3rd party cooler, cm hyper tx3 evo. I even removed and reapplied the thermal paste but the temperature is still the same.. sweat.gif
*
I don't think Hyper TX3 is sufficient to cool down the A10 5800K, though you could probably use higher CFM 92mm fan, or put 2nd fan to make push-pull

Have you tried running your PC with sidepanel open? That is the best way to determine whether your PC circulates enough airflow inside.

so I have just 1 fan on the tx3 evo right now.. is it better to set the fan to pull air or to push air?

You could try experiment on your system. Try to switch from push to pull and see whether that changes the temperature.

How to know that heatsink actually make proper contact with the cpu?

I tried touching the base plate after shutting down the computer but I didn't feel any heat. Does the heat lost very quickly? hmm.gif
*
To check for proper heatsink contact, check how thermal paste coverage when you pressed the heatsink against the CPU.

Your heatsink is using HDT (heatpipe direct touch), use this to properly apply thermal paste on it.

QUOTE(sulfuriq @ Dec 18 2012, 02:01 PM)
General Rule
More surface on the Heat-sink, the more the heat can be disperse quickly
The larger the diameter of the fan, the more surface area it can cover
The higher the static pressure fan rating, the more air can be pushed within the heat-sink fin.
For heat-sink fan always go with the higher static pressure
*
Don't be ridiculous. CM Hyper TX3 Evo could only fit 92mm fan. When fitted with 120mm fan it will be bigger than the heatsink itself, thus less airflow going though heatsink itself and the motor of the fan is larger than the 92mm fan means more dead spot (no airflow) on the fins. I have 92mm heatsink before (Arctic Freezer 64 Pro), fitting 120mm fan isn't the solution to get better performance out of it. Only way is to get higher CFM 92mm fan.

Another question, why is the temperature for the CPU and HD 7660D different?

Shouldn't the temperature be same since they are on the same die?
*
Physically yes they on the same die but they load differently thus different temperature and incorporate power gating which reduces voltage and clockspeed of certain light loaded units of the APU (like when using CPU intensive program, the CPU will get all the power while the GPU being clocked down and reduced voltage).

Whats the point of upgrading since in real world performance you wont feel anything. 1055T still has 6 floating point unit compare to FX8350 which has only 4 . Wait for steamroller better. Piledriver is just a minor upgrade from Bulldozer.
*
Performance don't measured by just the number of FPU, this is the reason why AMD chose to build CPU in modules with shared FPU because most programs do integer calculations. By your logic Streamroller going to be worse because they streamlined the FPU area even more because more shared units

But I do agree you should stick with Phenom X6, as I did with my X4. I don't feel like upgrading since even whatever benchmark scores says Intel is better bla bla bla, all games runs great on my hardware smile.gif

Better wait for Steamroller. A question, Steamroller will be manufactured at 22nm or was it 28nm?

Its 28nm, GlobalFoundries isn't as advanced as Intel fab. They need to unify everything to 28nm so its easier for them

Jaguar architecture looks real interesting to me. I been reading its capability for the past few months. I'm hoping some low power tablet or good ultrabook-like ultraportables comes out with it in it. Bobcat is a step up from Atom, but I had tested it before on ASUS laptop. It's not as fast as I wanted when in power saving mode. I hope Jaguar will fix this

if i ignore the gpu of a10-5800k, and buy new high gc, is it wise? or just buy other model of cpu +gc straight? is the new 6800k is locked version of oced 5800k?
*
Of course not. The purpose of buying FM2 platform is because of the integrated GPU. If you going to buy dedicated graphics card better go for AM3+ platform if you wanted to go AMD.

The 'K' in AMD platform is the same as on Intel platform, which means unlocked multiplier for overclocking purposes

is majority FM2 platform integrated GPU but not all. example, Athlon X4 750K & 740 is FM2 socket processor but did not included integrated GPU. both models I guess not available yet in market, should be replacing FM1 AMD Athlon X4 651K 641.
*
I do aware some FM2 CPU don't come with integrated GPU but since the CPU isn't as fast as AMD FX it would be wiser to go AM3+ platform unless the CPU is great for overclocking and/or cheap compared to AM3+

L2 cache is 2MB per module, so there is 2x2MB L2 cache, the L3 cache is halved from its bigger brother, from 8MB to 4MB.

I would rather they opt for quad channel memory rather than expensive GDDR5 memory. GDDR5 memory should be good for laptops because it's embedded but for desktop you are stuck with whatever that is available on the motherboard
