Are you referring to me? Yes I'm using Sapphire but I overclocked it to 980/1180 only.
1000/1170 is great achievement though. hehe~

GPU core speed n its memory core. Which 1 OC higher do their job better?

Guys,

Any 3Dmark results for HD4890 crossfireX and single HD4890
my pc spec:

CPU : E8400 @ 3.6Ghz
RAM : 2GB
Mobo : MAx 2 Formula


mine :
Single ...... .................... CrossfireX
3Dmark 2003 > 62880+- ...... 97,680+-

3Dmark 2006 > 16,500+- ...... 18,900+-

Vantage > 10,000+- ..... ............... 16,500+-
(graphic at performance)

im using sapphire 4890 1gb also
tried OC-ing through Overdrive
even in slight adjustment, i can see a lil mili-stud in several seconds in 3D mark vantage
my eyes quite sensitive, so can definitely see the difference in each OC increment

still benchable though, no artifacts for those slight increments
didnt bother, set to default afterwards

performance increased a lot?
i benched only using 3dmark vantage
set to default after seeing a measely <5% increase in GPU score

This is the result before and after OCing both GPU and CPU for 3DMark VANTAGE~


Attached thumbnail(s)

HT off?
on the HT and u'll see a significant boost

8 Threads, 4 cores. HT is on.

Good OC ...

gto87 only on HT at before-oc clock

thanks for confirming my eyes

if on HT, can reack 20k on CPU score

on 4.0 it reached 24k with HT on

Thanks Bro.
I'm aware of that, but I'm still a noob in OCing i7 proc. I'll try with HT on later (but the temp goes like )

To everyone who has problems with getting Radeon 4890 to work with rivatuner, please try this page. Downlaod what they told you to download.

this is an interesting read

4890 CF vs GTX285 SLI
http://www.xbitlabs.com/articles/video/dis...i-hd4890cf.html

I am so tempted to get HD4890 May I know which brand is reliable? Is Sapphire reliable enough?

the performance difference , trade punches?

Its weird..according to member's with long epenor here...4890CF is nowhere near GTX285SLI performance.

Backthen Xbitlabs did said that CrossFireX configuration was abit hassle...but now no more? or they just keep it silent?

where can compare like that it should be against GTX275 SLI instead

GTX285 is faster than GTX275 la..

CF and SLI is for rich people only bro.

9600GT SLI is considered for rich ppl? right.........
