XFX GeForce 260 GTX - Varmt/Kaldt under load ved overklokk?

[HLSolbjorg]

Hey!

Skal ha XFX GeForce 260GTX 480MHz kortet, og lurte på om kortet er varmt eller kaldt under load (Crysis, Crysis Warhead), Evt. temperaturer.

 

Har sett på hjemmesiden til xfx, og de har tre versjoner av kortet.

 

Så jeg vurderer å klokke kortet fra 480MHz til 666MHz, men vil kortet bli veldig varmt da?

Kan jeg bare "gå rett på", eller bør jeg klokke 10-15mzh om gangen, og benchmarke mellom hver gang?

Performance

GPU Clock MHz

The main attributes of the GPU are the core clock rate, which typically ranges from 250 MHz to 1200 MHz in modern cards.

576 MHz 640 MHz 666 MHz

Shader Clock (MHz)

The number of pipelines (vertex and fragment shaders), which translate a 3D image characterized by vertices and lines into a 2D image formed by pixels.

1242 MHz MHz 1440 MHz

Stream Processors

Through the use of stream processing, computer benefit from the ability to transparently access a large number of 'cores' (or, computational units) on a chip without having to separately manage each and every one of them along with their associated busses, memories, I/O, etc.

Texture Fill Rate (billion/sec)

This is the speed at an image can be rendered or "painted". This rate is specified in texels per second, the number of 3D pixels that can be painted per second. A texel is a pixel with depth (3D). The fill rate comes from the combined performance of the clock speed of the processor and the number of pixels it can process per clock cycle, and will tell you how quickly an image can be fully rendered on screen.

36.9 Billion/Sec 61.44 Billion/Sec 63.94 Billion/Sec

Vertices/second (Billion)

Graphics chips don't work on curves, rather they process flat surfaces. A curve is created by multiple flat planes arranged to look like a curve. 3D objects are created with multiple triangular surfaces, sometimes hundreds or even thousands, tessellated to represent the curves and angles of the real world. 3D artists are concerned with the number of polygons required to form a shape.

Pixels per clock (peak)

This impacts on the rendering capability of the GRU. The clock speed itself is not the critical factor. Rather it is the per-clock performance of the graphics processor, which is indicated by the number of pixels it can process per clock cycle.

Memory Type

VRAM was typically based on DDR technology. During and after that year, manufacturers moved towards the vastly superior DDR2, GDDR3 and GDDR4.

Memory Size (MB)

the video card will have its own video memory which is called Video RAM or VRAM. The VRAM capacity of most modern video cards range from 128 MB to 2.0 GB.

Memory Clock (MHz)

The memory clock rate in modern cards are generally between 400 MHz and 2.4 GHz.

Minimum Power Requirement (Watt)

This is the minimum power supply wattage requirement for the graphics card to perform properly.

Cooling Heatsink

Generally referred to as a passive cooling device, it has no moving parts and, therefore, is soundless and very reliable; it absorbs and dissipates heat from the GPU using thermal contact (by either direct or radiant contact with a cooling medium such as air).

Cooling Fansink

Sometimes known as an active cooling device, a small electrical fan which drives air across a heat sink and as such will generate a small amount of noise. It is more effective than a heat sink alone at cooling.

Og hva kan jeg klokke på kortet egentlig? xD

 

Kan jeg klokke:

1. Memory Clock

fra 1998MHz->2300MHz

2. Texture Fill Rate

fra 36.9Billion/Sec->61.44 Billion/Sec

3. GPU Clock

fra 576MHz->640MHz

4. Shader Clock

fra 1242MHz->1440MHz

Uten at kortet blir altfor varmt?

Er det en måte å sjekke om kortet blir for varmt under load (Benchmarks?), og hvis det blir varmt, får man bluescreen elns da? Safety Shutdown elns?

 

 

Sist men ikke minst, vil jeg merke noen stor forskjell?

Hvor mange frames vinner/taper jeg ved å klokke?

 

Takker for alle svar

skjermkorta nå for tiden er enkle å klokke, omtrent så man kan bare hoppe rett i kjøttet med toppklokk,men det ville jeg naturligvis ikke gjort. selv om kortet er bevist å klare den klokken med standard kjøler så ville jeg prøvd forsiktig med engang. 15-20mhz om gangen til du kommer i mål. tempen øker ikke så ekstremt og korta er laget for å tåle juling. så lenge kortet ikke kommer opp på 90 tallet eller bryter 100 så er det greit som max-temp. nvidia selv hevder at 200-serien skal takle temp opp til og med 105c uten å ta skade,men ikke ta det for god fisk, de er selgere;)

 

pass på å kjøre viften på en god hastighet på bekostning av støy dessverre og et godt ventilert kabinett er en klar fordel.

 

klokking vinner man ikke allverdens på, 5-10fps snøtt nok, 15fps toppen dersom du baserer på en tung klokk (suicide-oc). for å kunne vinne litt så ma du klokke hele systemet omtrent. core-oc er ikke nok til å utgjøre noe stor forskjell. mem,shader og core burde klokkes for å få noe uttelling samt cpu. jeg har ldri vært noe stort fan av overklokking da det sjeldent gir noen merkverdig uttelling på fps-rate,men bare tærer på hw.

 

standard-klokk gir mest stabilitet og varer lengre;)

[HLSolbjorg]

Ok

 

Så da er det ikke no vits å klokke kortet egentlig?

[Nostalgisk]

du vinner så lite på det at det ikke er noe vits praktisk talt. som sagt så er det kun snakk om toppen 10fps foskjell fra der du er å.men vanligvis så er det ikke noe mer enn 5fps.

 

så nei, det er ikke noe vits egentlig
