that would be brilliant, that way we can see how much every extra OC helps
Just as an info.. several sites reviewed ASUS "Voltage Tweak" edition, which alows up to 1.45V for GPU trough ASUS Smart Doctor. And all of them got up to 1GHz stable (on air), though some had to lower memory slightly, but everyone was over 4000MHz.
edit:hardwarezone got 1000mhz core and 4800mhz mem, tis awesome, very awesome
I have few more, but I don't have them in favorites but in a forum post on another forum.. which is down at the moment, sorry :/
managed 1000 core and again maxed out mem in CCC with voltage bump thats with 1.35v compared to 1.31v stock, oh, and 2d mode is 1.05v
just got this but think i need more voltage coz it started getting a few artifacts after a few minutes, but hell.... think its just the high oc on the memory thats artifacting. wonder if u can bump the voltage to the ram chips...
1025MHz core 5004MHz GDDR5
edit: somethings wrong here the fill rate and bandwidth went way down...
Nice mandelore, I was wondering when someone would hit the 1Ghz mark on one of these! How are temps at that level of voltage and oc?
Vantage stable 1000 core, 1150 mem (reduced mem just incase it buggered it up)
only 4.1ghz cpu tho so can get higher when i ramp that up P13037, not bad for a 1st time vantage run with this oc, oh and 68C max temp on GPU
mandelore, two questions:
- what was the fan speed at those 68C, and after how many runs? sounds like some nice temps for 1GHz (if not too loud)
- VoltageFactory already works with HD4890??
U gotta add the config file to rivatuner, then voltagefact works nicely. fan speed is 100% for those temps, but it doesnt really matter as ill go watercooling soon as the blocks are available. im expecting much lower temps once that happens.
2 runs of vantage. i may not even require 1.4 volts to get 1k on the core i just set it to that as a failsafe, now comes the part where im gonna re run at ever decreasing voltages.
so far im stunned by this card
Hardware Canuks had a nice review specific to the sapphire card
Here's a screenshot of their results.
Here's how you get a decent overclock with the HD 4890
where did you get that voltage factory soft ?
Though there is version 1.1 of Voltage Factory in their forums here..
Im sooo jealous. I want a 4890.......soon crtecha......soon
I almost wan't 1 just for the voltage factory and then to put it under water.
But I'll wait... 5 series maybe.
Heh I guess there's not much else to talk about now except R800/RV870
300 series from nvidia is coming soon q4 this year and it's rumored to be one of those amazing tech leaps that we saw from the 7 series -> 8 series.
I don't believe it, but if it's true I will be looking for a possible single card solution.
Meh, I used to be all about multi-GPU but as my monitor is limited to 1680x1050 it doesn't make much sense for me. In particular I was won over by the 4870 512MB because it's performance was often equal to a 4850 xFire setup at my native resolution.
3DMark05 @ 1000/1100 with my new ASUS 4890
Just got the card in today from NewEgg. Took out the 4870 and threw this in @ 950 / 1100. Played some COD4, COD5, FarCry2, and Crysis at this speed. Every game was 100% stable.
However 975 / 1100 things became unstable. I fallowed Mandelore foot steps and set vCore to 1.35 with ASUS SmartDoctor an now I am playing COD4 + COD5 with 1GHz GPU Core
Onto the Benchmark ScreenShot.
BooSFeD - good work I guess that just as mandelore you've been running on 100% fan, right?
Btw, now you can update your system specs, still says X1800 & P4
Have the fan spinning at 60%. GPU does not load more than 70c in games. However it is loud and I'm def. waiting for waterblock.
70c isn't too bad considering you've given it more voltage already.
I wish I was in the market... I would so buy 1 or 2 of these cards.
not a great gpu score but just starting again with ati cards
repeatable clocks np,not any higher thuo worse scores or crash
temps ok email@example.com
i wish i could find out why i cant run other fm 3d compleat tests....always crash in 01 03 nature saying bla bla dxerr, 05 gt3 and 06 sm3.0 bla bla some other crap jeez i'll try in xp
