XFX HD 4830

I'm going to jot down my initial thoughts and bit about its overclocking ability.

Setup 1

Athlon X2 5050e 2.6GHz 1MB L2
2x1GB Super Talent DDR2 800
Asus M3A78-EM 780G/SB700
XFX HD 4830 512MB
Vista 32-bit

Setup 2

Athlon X2 7750 BE @ 3.0GHz
2x1GB OCZ DDR2 1066
Asus M3A78-EM 780G/SB700
XFX HD 4830 512MB
Vista 32-bit

Setup 3

Athlon X2 7750 BE @ 3.3GHz
2x1GB OCZ 1066 DDR2
DFI LP Jr 790GX-M2RS
XFX HD 4830 512MB
Windows 7 Beta 32-bit

Aesthetics

The card looks great! Typical XFX quality all around. It has a flat black finish, a black PCB and a black PCI bracket. Did I mention that its black?

Cooling

First off, with the stock fan profile the 4830 idles around 38 degrees and loads in the low 50s! That is a huge difference than what I used to see with my reference 4850 and 4870. Fan noise is pretty quiet as well but picks up a little as the card is loaded (obviously).

Overclocking

The factory clocks are set at 575/900. So far I have it 3DMark06 stable at 802/1074. Any memory frequency above 1078MHz causes instant artifacting on the desktop. In addition, overclocking the core and memory haven't raised the load temps above a couple of degrees.

i've read 4830 crossfire is nearly as good as 4850 crossfire.

have you plans to go Crossfire?

and great thread :thup:

thescavenger · Jan 21, 2009

Peformance between a 4830 and a 4850 is nearly identical. The 4830 will just run a lot cooler.

I will definitely go Crossfire when I get my X58 board.

2 x 4830s = $250!

Thats not the only difference...

The 4850 has 800 unified shaders, the 4830 has 640 unified shaders

Other than that they are the same

Thanks for pointing that out.

In my experience those extra 160 shaders are only noticeable when using hi-res, hi AA/AF settings.

Rich'[ard] · Jan 22, 2009

hmmm, i'm tempted

reckno you can crossfire 4850 and 4830 then? it should give the same performance as 4850 crossfire if what you said is true.

4870 + 4850 crossfire means the 4870 runs at the speed of the 4850 yeah...so if a 4830 is pretty much = to 4850, it should be nothing to worry about!

What about tri-fire with the new hydra chip (fingers crossed its coming soon). That will outperform the current HD4870X2 no doubt

Exactly!

I had a 4870/4850 setup for awhile. That particular 4850 was a terrible overclocker which restricted my 4870 to 700MHz.

thescavenger · Jan 22, 2009

Bump for higher clocks!

Rich'[ard] · Jan 22, 2009

i can't get my model 4850 anymore the shops here in Melbourne don't stock them anymore. and they' don't come with Crosfire connecter/cable so that's annoying.

i might pick up a 4830 then, if you can Xfire with them :thup:

EdwardTobia · Jan 22, 2009

Ive been hearing about the 4850's as bad overclockers but i have to say mine is amazing!

I managed to hit 800 on the core and 1200 on the memory (2400 effective) which was stable ingame for around a while but then would freeze (not due to heat, temps are amazing), with slightly more voltage it would be stable...

I leave it to run at 730/1100(2200 effective) for everyday use/gaming, i may vMod one day to reach 800+ core speeds and higher memory speeds...

Maybe im just lucky and had a good OC'er?

Just to clarify, did you mean 4830s or 4850s?

I meant the 4850's

Btw i see you have got a great overclock on that 4830, i can reach 800+ core speeds with some extra voltage, did you manage to hit that stable with stock voltage?

I can hit 800 core but its only stable for around half hour of gaming then it freezes, with extra voltage i could make it stable...

I may get one of these 4830's

Kuroimaho · Jan 23, 2009

I checked in ORB the results are very close to the 4850, if it stays the same in RL this a real killer buy.

Runs off to check 4830 prices.

Congrats man that was well done, 3rd place in ORB...

thescavenger · Jan 23, 2009

This is all on stock volts.

What am I in 3rd place in?

Rich'[ard] · Jan 25, 2009

great stuff!

have you tested 3dmark06 since you reached your highest clock? results would be awesome

Yep, I got 10,197. A decent dual-core would really unleash this beast :bang head

cool thread

thescavenger · Jan 26, 2009

Thanks!

I added a 3DMark Vantage score.

this inspired me to build a 4830 CF set up one day
