Just finished overclocking HD4890 to 990/1170

Test it with Crysis FPS
1920x1080, all set to very high, 4xaa

Result.. FPS = 18FPS - 23FPS
Fan speed = 100%
Load temp = 69c
and I took the FPS reading while playing in one of heaviest shooting scene.
Played it for one hour straight. No blue screen..


Somebody asked for the details on the driver version that comes with the card for the HD4890 GC. here's the info about the driver.

Driver Packaging Version 8.592-090303a-077127E
Provider ATI Technologies Inc.
2D Driver Version 8.01.01.882
2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/Class/{4D36E968-E325-11CE-BFC1-08002BE10318}/0001
Direct3D Version 8.14.10.0647
OpenGL Version 6.14.10.8543
Catalyst™ Control Center Version 2009.0303.2224.40202

EDIT: very tired.. and will continue OCing later tonight.

but hope u know whats the cost to watercool a gc..
its almost buying another gc.

Added on April 2, 2009, 4:07 pmalso gtx285 ftw (stock fan speed) sli tony hawx 1920x1200 8xAA 8x AF is 94fps average, max 300.
hd4890 oc 900/1000 (stock fan speed) crossfire is at 71fps

this was my initial test today ..

both running single raptor x.. hdd

tried to make it clean installation for the crossfire setup.
the nvidia drivers was causing some issue.

i would say that reviews between 4890 vs gtx200 series card is pretty mixed up. =_=

on post #436 by X.E.D, seems that in game testing, the 4890 OC'ed can really perform in most games against the GTX 275 or 285 even

dun mention GTX285 OC'ed, its price is unreasonable =.=

Try lurk around HD4890 oc results, differ website will give differ outcome

thats really funny

ure comparing a 1k card with a 1.3k card which part is unreasonable??
prices above 1.3k is usually game bundle, extra warranty etc.

and u dont mind a vacuum hoover sound at 1ghz when it cant run at stock fan setting
compared to a 1.3k card with stock fan setting overclock..

anyways i have both cards on sli crossfire.
waiting for new drivers before i post results

but i can tell u now the hd4890 is a bit buggy and is slower than my gtx285 flashed to ftw bios.
if 1ghz is equivalent to a gtx285
a gtx285 ftw is around 11 percent faster would means a hd4890 has to be clocked to 1.1ghz.
anybody can tell u the ftw speeds are easy to reach

yesterday i saw czone selling sapphire model at rm999 for the card.

My arse. ~1350 for a cheapo 285, 14XX for something "proper".


Looks like you have an agenda against certain companies so why should we trust whatever you say. More so in semi intelligible English.

actually what do u mean by proper? coz afaik even those 1.5k GTX 285 are all using stock cooler. what cstkl1 means is that regardless of 1.5k or 1.3k GTX 285 may be, most of them are using stock cooler (but of coz now there are non-reference 285 with better cooler coming soon, maybe that's what u mean?). It's just that Nvidia's stock cooler is doing extremely well IMO (and also stated in other sites), you don't really need to set the fan speed to 100% for 285 just to reach very high clock speed, coz their auto fan speed normally tend to be able to handle the higher temperature

not to mention nvidia cards consume less wattage compared to the radeon cards

I meant proper as his "game bundles, fancy packaging, warranty" as if SEA region cards have "better" warranties at all. Even at RM1350 the 4890 is RM400 cheaper, and that's a lot of money that you can spend on the card/elsewhere. They're still selling cheapo 285s at 1450+ here (Melaka) so I could raise more hell actually.

[H] and FiringSquad said they did not need to change fan to 100% to OC to 900+.

And the 4890 uses much less wattage than the 275, which draws power almost like an 285.



If you want better idle power, just flash the BIOS with lower GDDR5 clocks and voltage. From observation however, looks like GT200 heats up much faster (uses more power) once you touch core and shader clocks.

lol speaking of power consumption, I've found this from techpowerup



and i was like wtf? higher than GTX 285 and 295??? maybe it's due to poor driver support?

I can c noob juz posting graph over n over again...n try to act pro like he know 'everything' compare to people tat does OWN the card and tested it him self...

F**king Fanboy really make thing hard aite...

gtx275 high power consumption might be due to immature driver.

right such a fanboy

Added on April 2, 2009, 7:49 pmive already said 900 is ok on stock fan indirectly ..anything above on crossfire testing both dvi is not possible stock fan
but hey keep reading on and posting screenshots and links
its more like ure convincing ureself only

current driver for the hd4890 on crossfire is buggy

theres a lot u can tell about ati since fan boys dont even want to admit

overclocking ati cards especially hd4000 depends also whether ure using both dvi's or not aka dual screen or 30 inch monster.

Why on earth are you(both of you) comparing two cards with different price ranges?

[H] is a good site if you're looking for highest possible settings on a gc. Of course, some ppl prefer more fps though.

Oh, anandtech got their reviews up http://www.anandtech.com/video/showdoc.aspx?i=3539 .

well just saw the zotac gtx275 amp version posted

the clocks are exactly the same other than than the shader compared to the gtx285amp
but its higher than the stock gtx285 for core and mem, while shader is the same.

this is really interesting

hope the gtx275 doesnt have a lower core/shader ratio.
if not that heck its going to clock as good and perform as well .
only limitation is the mem amount for high res. compared to gtx285.

looks like gtx285 is going to be eol folks.

Oh and, quite a lot of games actually.

Just to fix your statement .

LOL....typical nvidia fanboy...

basicly we get what we pay for. at 900 range . 4890 is a good deal already .

most of us is normal user only , we dint OC or maybe oc abit. , we dint CF or SLI. that why the 4850 sell like hot cake when it 1st come out.

we seek for best price performance or best value card . not the extreme to top end card lol .
