Ati radeon 4890 Overclocked to 1.35 Ghz

[Tempered81]

I saw one at 1466mhz, but cant find the screenshot now...Makes me wonder what the 40nm high-end will do. Btw, this is done on LN2 cooling. The highest air cooled overclocks are usually in the 1000-1100mhz range (and sometimes requiring increased vgpu). Just for kicks - check it out:

Mine autotuned to 990/1125 with stock V (I assume autotune doesn't change voltage), I need to find out what mine can do sometime soon.

now that's amazing!

Sweet. Crazy clocks on that 4890.

 

[Nathelion]

Anyone else find those temperatures funny?

 

[yh125d]

Except the first GPU temp yeah. 400C+ is off a bit...

It's obviously a misreading thermal sensor, which is to be expected. These parts aren't made to run LN2 cooled at -50C.

This.

Nice OC...wow!!
Too bad LN2 is so expensive

Lovely overclock, but... what about performance improvement?

 

[Phew]

Wonder what the core voltage on that OC was.

must be crazy fast for a single gpu, i think

LN2 itself is actually quite cheap, something like $2/L

Really? Wow.
Here in Jamaica, I don't know if anyone uses it for CPUs....LOL!!
Maybe in a few years, I'll be the first.

here is 1430mhz core:

Meh, you're really not going to damage it.

Careful with that, autotune might clock it too high.

Its perfectly stable in WoW, COD5, HL2, Far Cry 2, Fallout 3, so it's not too high for stability as far as I'm concerned

I do not think he is talking about damage, just that the thermal sensor is a bit out of its expected operating range
