Extreme Overclocking: The Ati 4850

[Kuronin]

I've done a little research (Benchmarks on OCC and reviews on newegg)

 

And I would like to purchase a 4850, but there are so many versions out there!

 

I am looking for one that overclocks like crazy, someone on newegg said they got theirs to run at 750MHz without actice cooling.

 

I narrowed down to a few, mostly factory overclocked.

 

HIS IceQ4

ASUS Top Overclock

Gigabyte 1GB FC

 

Or any other cards brought to my attention. Right now, I am leaning towards the Gigabyte, but the absence of overhead will ruin it for me.

 

Your input is much appreciated.

The Sapphire Toxic Version looks good.

Nobody can tell you how much a card is going to overclock. Every chip is differant, just like every cpu is differant. The card you get might overclock really well, or it may not.

If you don't mind MIRs, I would go with the ASUS one.

 

The Gigabyte one is more expensive and if you take a look at the specs, they actually downclocked the RAM to 960MHz instead of the 993MHz. I would not expect being able to increase the RAM clock a lot further than that.

 

Good luck

whats the point in paying $200 for a 4850 when you can get a 4870 (with higher clock) for $220?

 

 

edit: even cheaper! PowerColor 4870 OC

[dr_bowtie]

that is a pretty sweet price and it's only 40.00 more than the 4850

[Kuronin]

Wow, that's awesome! Thanks hornybluecow. That's even 4870.

 

Anyways, in my defense, the mem clock WAS slowed down, but you are getting 1GB of it, instead of 512.

 

And in my opinion, you can generalize when talking about the overhead of a certian card. Some cards just have more room for overhead than others.

Extreme overclocking of the 4850

 

I think you have the wrong thread name it should be overclocking 4850, unless of course you want to do some serious EXTREME 4850 overclocking and run at a 1ghz core :thumbs-up: then look at the following links :thumbs-up:

 

and just get a standard 4850 and buy a big gpu cooler ie acellero/thermalright vga cooler etc or if you want to really go for the EXTREME get a gpu waterblock for watercooling or go to the max with phase change cooling (but i doubt u will ever go phase only a few elite overclockers do this <_< , and for temps with phase expect in the negatives around -60 degrees celcius :thumbs-up: )

NOW THATS SOME EXTREME 4850 OVERCLOCKING

[abid]

i would go for the sapphire toxic... its cool!

[n4mr3h]

Go for sapphire toxic, it's better and cooler with zalman HSF

[tanka12345]

I would go for the Sapphire Toxic too.

[IVIYTH0S]

that 4870 from power color is a good deal but it's a 512mb so it's not as worthwhile as the 1gb version (unless you wanna buy mine which can overclock to 880mhz)

 

Aside the fact that I'm running an asus 4k series ATI, I still think the 680mhz asus 4850 is a hard deal to pass up because of how cheap it is
