HD4870 Overclocking (3dMark06)

READ DESCRIPTION**

Here's a really boring video, no music, no speed, nothing - just a couple of clips showing off the speeds and score of the CPU, PCIE and HD4870 in 3Dmark06.

(You'll hear bits of MassEffect in the background, I was playing on the Xbox in the background while tests were rolling)

There's a number in the left corner that shows the current speeds for the setup, so you'll be able to jump in the video easier.

Notice: GDDR5 memory is counted ex. (DDR*4) 900*4 = 3600mhz

1. 100% stock-speeds
CPU: 3000mhz
GPU: 750/900
Score: 11.107
2. Increased videocard speeds
CPU: 3000mhz
GPU: 780/1055
Score: 11.268
3. Further increased videocard speeds
CPU: 3000mhz
GPU: 790/1100
Score: 11.283
4. Overclocking CPU and Videocard
CPU: 3225mhz
GPU: 790/1100
PCIE: 111mhz (+11mhz overclock, forgot to test this earlier)
Score: 12.027

Much of the additional performance in 3dMark06 was due to the extra CPU power - but I'm still not sure if the PCIE frequency did have a great impact on the performance, I will test this later today and return with further information.

Do also notice the videocard ran quite hot on the overclocked tests and fan-speed therefor increase rapidly but still ran free from problems which talks for further overclocking possible with stock cooler outside the Catalyst Control Center Overdrive utility.

Configuration concludes:
MSI K9A2 Platinum 790FX/SB600
AMD Athlon X2 6000+ @ 3200mhz
2GB OCZ 860mhz RAM (CL4-15)
Sapphire Radeon HD4870 512MB GDDR5
Thermaltake Toughpower 750W
Creative X-fi Xtreme Gamer
Western Digital Caviar

where i can get that overdrive program for my 5770`? thankyou

[BorkaBonum]

@AaastaZetaan

Overdrive for the videocard is already available on your Catalyst Control Center module - alas, the drivers for your videocard.

Overdrive for the processor, RAM, etc. can be found on AMDs website. Just google "AMD Game" and you'll find the proper site for their drivers and utilities.

well, i have a problem,

I overclocked mine and i guess it was faaaar off the requirements?

Everytime catalyst control runs, my computer screen gets all these colours and freezes.

Is there anyway to stop this from happening other than disabling my graphics driver?

please help

@williamjeon

Disable the Overdrive thingie in Catalyst Control Center.

It could be a driver issue, your model being "bad" or your videocard kicking too low voltage. The latter can be fixed by certain programs depending on your videocard model or by firmware mods, both is mildly risky and will increase energy consumtion and temperatures noticably.

Holy 80deg batman, seriously your a moron, back off the over clock. You may be fine for awhile but it will shorten your cards life in the long run if it doesn't fry it in a couple of days.

@xXDMCdanteXx

It ran like this perfectly for 18 months before I replaced it with a HD5850. These chips are designed to run fail-free at up to ~100-110*C before clocking themselves down slightly and by around 120-130*C it'll shut down. High temperatures risk shortening to lifespan - however you still have a longer warranty than you'll reasonably use the product.

84 ° c and very hot!

you have to increase the speed of the fan!

I have a intel pentium d 3.20ghz dual core and 2gb ddr2 700w psu and sapphire hd 4870 512mb how much should i overclock can anyone help me with this?

[zealot50]

what program did you use to overclock your CPU AMD Athlon 64 X2 Answer me porfabor

[crackkn]

I HAVE HD4870 WITH A

CORE 2 DUO E8500

2x4 GB DDR2

ASROCK G31M-S R2.0 775 DDR2 MOTHERBOARD

550W POWER SUPPLY

[FOGoticus]

What did you use to overclock your cpu?

[JakeThaCake]

HD4870 84C idle, running like this 24/7 since 2008 july.

[SmexxiWaffles]

@OwnedEpicly I have a HD4870 1GB, and It runs just fine @ 75C - Even 90C Is a Runnable temp. They only start to die sooner if it does hit 100C +

[BorkaBonum]

@OwnedEpicly

No problem - ran like that for one and a half year, never a problem. All the HD4870 with stock-coolers came like that and the electronics can handle up to 100*C+ before the lifespan can be foreseeably shortened.

My brother is now using this card in his computer after I upgraded, and it's still working perfectly.

[DjmartinStach]

is it worth to overclock a HD 6850?

[aLieNcrYse]

LOL! I had a ASUS 4890 OC to almost 1GHz. Tepms was 75C max! :D

[kingweeka]

my hd4870 is oced at 800/1000 and run way cooler 60c under load
