In my country this PSU still abit high I guess but it is already discontinued and replaced by HX750i.

OK thanks for the information Chopper1591 thumb.gif
My 3930K OCed to 4.6GHz daily and I tested with CinebenchR15 also R11.5 it draws 162watt from HWinfo64 sensors. Stock is 130watt, my card is not to good for overclocking so I just set to 1050/1350MHz without adding volt, I guess my rig won't draw more than 500watt rolleyes.gif
Your card is great, hmm I am abit confuse should I sell my card and buy sapphire R9 290 tri-X like yours and OC it up to 1200MHz or a GTX 780 Lightning, they are used cards so I would get cheap prize biggrin.gif

I know, the hx is replaced. But it is still a decent psu. The new i-series have higher efficiency rating but that's about it. And sure, full modular is nice but not necessary.

Your good. For sure.
My chip uses a lot of power. When I try to make it stable at 5.0ghz (or above) it gets heavy. I need to up my voltage to around 1.575v for that. Consider the stock voltage to be "just" 1.375v, that is mad.

Again, measuring is always better. Maybe you have someone you know that owns such a wattage meter? Then you can just borrow it for a day and play around with the system. Decent ones also log the max values.

IMO, if you have to chose between the 290 and the 780, it does depend on the games you play the most though, I lean towards the 290. It also has 4gb vram compared to the 3gb on the 780.

I will.
Do note that scored can be different slightly because you have the stronger cpu.
But I will show you shots of: 1000mhz (stock) 1200 and 1250. All with default ram to minimize instability.

And about the ram.
If you do change, look into G.skill. They are by far my favorite brand at the moment. And I am a long time Corsair user (including Dominator series).
I have also seen some very nice Sammies (Samsung) kits here on the overclock thread. But on average the G.Skill just owns it currently. They also have multiple records in both DDR3 and DDR4 segment.

these are using old drivers. 1200 single . . .

http://www.3dmark.com/3dm/7690148?

1200 crossfire . . .

http://www.3dmark.com/3dm/6302964?

sorry no runs with just the gpus. i advise on keeping the quad channel. just remove a couple of 2GBs and add 4GBs . As close to spec and use same brand - Kingston.

We kinda get off topic here.
But here are the results.

Looks like the card actually uses a lot more juice when running 3dmark compared to Heaven. headscratch.gif
The core itself reached a peak Wattage of 276W during Heaven, with an added ~35W for the Vram.
3dmark peaked at 322W for the core alone. Wow.
Still I think my 750W psu should be enough. But I guess I should stick to 1200 on the gpu to be safe.

And now for the shots. All overclocking was done through Trixx.

Stock: Warning: Spoiler! (Click to show)

1200 core, 1300 mem with +100 VDDC and +50 Power Limit: Warning: Spoiler! (Click to show)

1250 core, 1300 mem with +200 VDDC and +50 Power Limit: Warning: Spoiler! (Click to show)

Can probably go higher when I mod the bios to reach higher voltage, but the power consumption is already massive so the gains versus the costs will most likely not be worth it. Temp wise I am very good. 41c core temp and the vrms 32c and 29c.

Make sure to open the pictures in another tab so you can actually read everything.

OK that is all that I need to know ^_^ thanks Chopper1591 thumb.gif those are nice scores with your Sapphire 290 Tri-X. Hmmm I thought Heaven benchmark uses more juice than 3DMark...anyway 3DMark 2011 also uses high voltage, I guess.

No problem. Happy to share.

And maybe it performs better because it is running on nice low temps? But I can't complain about it really.
In most games though, my cpu is holding me back big time. I've seen games (Project Cars, Assetto Corsa, GTA, Witcher) where Intel just performs way better. Still can't understand why. If games were to use one or two cores I would get it, but recent games has to be able to utilize the full 8 cores on my fx-8320. It's also optimization, I know. Especially Assetto Corsa and Project Cars, those games run so bad on Amd.

Here is a link to a benchmark:
http://tweakers.net/reviews/4021/3/project-cars-welke-hardware-heb-je-nodig-benchmarks-high.html

First chart are results with an x79 based system (4960x @ 4.4ghz). Second chart is the 990fx (fx-8350).

It is because current and recent generation Intel chips have massively higher IPC. Skylake is getting ~75% higher IPC depending. Even if you have a 4.7GHz+ chip you can't even match the stock IPC of a recent generation Intel chip with the FX stuff. The 83xx chips also only have 4 FPU's like a normal quad core, so seeing utilization across all 8 cores doesn't really mean anything on those.

Even if the games fully utilized more than 4 cores and saw actual gains from them, it would never make up for the poor per core performance.

And since you are using an AMD GPU you also lack CPU power to overcome the additional driver overhead which isn't helping anything.

Good explanation, thanks.

It is a world of difference alright. The fx line is getting ancient now. Back in the back it had a good price/performance ratio, and it still works okay by all means. But it just can't keep up. smile.gif
After all the chip was released late 2012.

Although I am curious about the upcoming Zen series of amd, I will probably upgrade to Intel. Its just too much right now: a new chip, board and ram. On top of that, knowing me, I need the good stuff. So the board will be at least € 150.
Current setup still works good though so I can probably sell that easily. Asus Sabertooth R2.0, 8gb G.skill TridentX 2400 c9.

As for achievement, yeah it's a good feeling thumb.gif. Thanx. Still that achievement depends on many things: the luck of the draw for finding CPU that operates at high frequencies with relatively low voltage, massive radiator space, reasonable ambient temperatures, mainboard quality, VRM cooling etc.

No problem. Happy to share.

And maybe it performs better because it is running on nice low temps? But I can't complain about it really.
In most games though, my cpu is holding me back big time. I've seen games (Project Cars, Assetto Corsa, GTA, Witcher) where Intel just performs way better. Still can't understand why. If games were to use one or two cores I would get it, but recent games has to be able to utilize the full 8 cores on my fx-8320. It's also optimization, I know. Especially Assetto Corsa and Project Cars, those games run so bad on Amd.

Here is a link to a benchmark:

First chart are results with an x79 based system (4960x @ 4.4ghz). Second chart is the 990fx (fx-8350).
I guess iinversion already explained about that smile.gif
Btw I also don't know much about this biggrin.gif

So that 5GHz can run daily in your rig? Great thumb.gif
Or do you prefer lower clock for daily usage?
Btw I just get up to 4.8GHz 1.38v for daily biggrin.gif still testing if it stable or not, I don't use Prime95 because it will generate too much heat for my H110, just gaming and 3Dmark benchmarking also cinebench ^_^ Btw here my 5GHz but only little test like Firestrike, unfortunately I don't have higher RAM speed, stock is 1600MHz but at 5GHz I use 1333MHz instead ^_^

The weird thing is : I just let CPU PLL on "Auto", if I let it "Enabled" then it will become unstable and I can't get boot to desktop at 5GHz.
Vccsa on auto (0,90v), CPU IO on auto (1.040v) and PLL on auto too (1.76v).

The 83xx chips also only have 4 FPU's like a normal quad core, so seeing utilization across all 8 cores doesn't really mean anything on those.

Even if the games fully utilized more than 4 cores and saw actual gains from them, it would never make up for the poor per core performance.

And since you are using an AMD GPU you also lack CPU power to overcome the additional driver overhead which isn't helping anything.
Thanks for the explaination, iinversion thumb.gif
