Lock On and power consumption

[Starlight]

I recently made some tests about power consumption.

 

My current Lomac rig is a superclocked SanDiego 4000@5200, with a 7900 GTO video card.

With such overclock, at full power it can reach 300+ watts.

 

On 3dmark06 and R6Vegas it reaches quite often such peaks, and never drops below 260-280 watt

 

In Lomac it rarely reaches peaks of more than 280 watts, and usually works well below, in the range of 250 watts, with lower and frequent peaks at 170 watts.

 

I didn't make scientific tests, I was just watching the watt'o'meter :)

but that was definitely the trend...

 

 

It just looks that Lomac either is energy-friendly (a kinda eco-Lomac) or that it doesn't use all the power it has available, for some unknown reasons... I was having about 50 FPS with a 4-ship F-15 formation over a town, max detail and full shadows, 1280x1024 res, 4xAA 8xAF

 

 

My next rig however is gonna be more energy-saving, given that the OC'ed E4300 that I have in the works runs at much lower energy levels... ;)

But you know that Lock On is a little older than R6:Vegas, don't you?

And of course, 3DMark is a kind of stress test, especially for your GPU.

Just compare the graphics of Lock On with those of R:6 Vegas and 3DMark.

I would be strange if Lock On would consume more power than 3DMark:lol:

 

Besides, 300W is a pretty high value.

Did you increase VCore?

sure man, it's my superclocked San Diego ;)

110% vcore, that is about 1.40-1.44, 3200 Mhz (320 x 10), Patriot DDR-600 @ 320 Mhz 2.5-4-3-6, and 7900GTO@GTX, plus some huge thermaltake fans (120mm, 90 CFM and *a lot* of noise each)

 

it makes SuperPI 1MB in about 26'', just as fast as a Dual Core E6400 @ default frequencies

the ram at such frequencies and timings have a read value of about 9.8 GB/s in Everest 4 Ultimate.

 

DDR2-800 @ 4-4-4-12 barely reach 7.5 GB/s on my E4300. But the E4300 is still in the works ;)

 

 

 

about Lomac. ok, it's not a last generation game, but I thought it was still using 100% of the vid card power. we all know is more cpu-limited rather than gpu-limited, but I thought it used all the available resources. New cards mean more advanced architecture and libraries, but I thought that resources were library indipendent.

well how can the video card be utilised 100% when it's the CPU being the bottleneck, which means Video card is "faster" then CPU (in terms of what work it needs to do) which means the video card is "waiting" for the CPU... right? :thumbup:

yet, I don't understand why other apps/games (still limited *also* by CPU) use 100% of the resources. More, Lomac sometimes goes down to about 60% of rersource use while in full 3D rendering and it seems it never reaches more than 80-90% while others reach 100%.

BTW, ok it's cpu-limited, but less than 60-70% of power means that also CPU is not fully exploited, because @ full CPU my PC runs at about 75% of power consumption. I'll make more tests when switching to the DualCore system, removing some CPU-bottlenecks (maybe)
