4890 highest core clock

Exeodus · Apr 15, 2009

I would go with the Thermalright.

Akrian · Apr 15, 2009

It seems that while XFX does some ipressive OC that is only holds true for an xxx version, not an XT one =( , and Asus kicks some major ass overall . So now I'm really tempted to get an Asus Card....

Sweet Clocks strange thing is I can get more FPS than the 4890...

How's that?
You have both? Or how did you compare?

I compared results from benchmarks on the net... I looked at the test system specs and most were similar or better than mine... Its quite suprising...

largon · Apr 15, 2009

Such a comparison is never, ever valid.
Multitude of reviews where HD4890 is compared to HD4870 show HD4890 is atleast 10% and upto 30% faster than HD4870 depending on scenario.

Yes, but there's no voltage tweak in XFX cards =(.
And which aftermarket cooler would you reccomend of the two ?
And yeah even though I never been a user of XFX before I hear that their warranty is awsome . And I don't rly like that much Asus warranty ( sending !@#$@! where to get your parts fixed ugh). But I really want to reach 970-1ghz =) on core ^_____^ and It's seems that voltage teak gives some advantage over other cards that do not have it , since you get more probability of achieveing higher clocks.
P.S. sorry for my grammar - English isn't my first language =)

you can just use voltage factory plug in for rivatuner,so get the cheapest.
i have the asus model and it clocks well with the fan up 100%

purecain · Apr 15, 2009

cowie would you mind uploading your asus 4890 bios..... thanks in advance...

cowie · Apr 15, 2009

i'm sry purecain i just took the card out last night and did not see your post asking till today :eek:

i knew i should have just dumped the bios when i first got it

mandelore · Apr 15, 2009

my ek water block arrived... wooooo!

26C idle, 42C full load @ 1000 core/1150 mem, 1.42 volts and running furmark stress test

gonna write a review of this thing of beauty

a_ump · Apr 16, 2009

very nice mandalore, that's 4,600mhz on the memory now isn't it? dam hope that baby doesn't die too soon

heres mine: 975 core and 1200 (4800mhz) first thing i did when i installed it bout 1 hour ago the mem slider in CCC was maxed out, so maybe more room there, stock voltage too

Edit: its a Sapphire card, came with 3D Mark Vantage, PowerDVD and a dvd suite

http://img.techpowerup.org/090404/4890 first oc.jpg

ohh ,that's great overclock on stock voltage , i like the memory overclock and see the bandwidth rise up cuz that's what the ATI card need , im think go pick up one like yours and crossfire it with my 4870 1G

grunt_408 · Apr 21, 2009

highest I can get is 990MHz on the core forgot to mention stock volts :rockout:

InnocentCriminal · Apr 21, 2009

:drool:

Maybe I should have got a 4890.

M_2 · Apr 22, 2009

wow 1000 Mhz core,
:twitch:

Purchased a Asus 4890 - 1Ghz Core 4600 Memory

This card is great, sold my Asus 4870 DK and purchased the EAH4890 voltage tweak.
I wanted 1ghz core and did with no problems. Also hit 1150 (4600) memory speed. Core V set to 1.375
Ran Crysis warhead and Farcry2 at max settings with both set to 8X AA. My OC'ed Asus 4870 DK (825 Core/4000 Mem.)was not fast enough to run 8X AA. This beast will eat through
8X AA period. Ran Farcry2 included benchmark program with the above indicated settings and got a 35.5 FPS average. Purchased from ewiz for 224.99 after the 20.00 instant rebate they had last week. Great overclocker. People are getting core speeds over 1ghz using rivatuner. Someone hit 1025Mhz core speed on air.

purecain · Apr 23, 2009

@cool mike... could you please use atiwinflash to save your bios and upload it here....

thankyou.... as of yet not one person has uploaded a working version of an asus 4890 bios...

gpu-z only extracts 64kb of the bios... this card has gddr5 so the bios size should be 128kb.

Cool Mike · Apr 23, 2009

Sorry, Not sure how to do what you ask. I do not that deep into it.

hmm. It is not hard d/l ati winflash from the download section on this site. Extract and run as admin (make sure catalyst control centre is closed or it will not run) click on save rom image give it a name then compress it into a zip folder then upload it to here

Scrizz · Apr 24, 2009

who wants to buy my 2 4850s

TSOWW · Apr 24, 2009

I try flash asus bios on my HD4890, but asus SmartDoctor always say not found asus display card. :banghead:

My HD4890 only 950/1100.i try use rivatuner add Core Voltage, but run 3dmark say lose driver.

The way you are typing you are not making very much sense at all, if possible please check the grammar of your post.

I think he means that his card VPU recovers/stops responding even after using rivatuner to increase voltages for a more stable clock.

eidairaman1 · Apr 24, 2009

for 1 he doesn't specify Which 4890 he has, 2 I dont believe RivaTuner Supports the 4890 Currently or needs to be revised.

Agreed.

It can adjust voltage though.
