XFX 4770 overclocks like a champ on air

Sneak-peek: We push the XFX 4770 in our Labs to an astounding OC level!

Overclocking is something that makes us weak at the knees, especially so when something is unexpectedly awesome at it - the XFX 4770 both doubled us over in joy and punched us in the back of the skull with it's overclocking prowess.

It's the first 40nm desktop graphics card we've looked at yet, and with the full complement of 640 shader units running at 750MHz stock it was dying for some tuning.

We threw it into our testbed and fired up Catalyst, hitting the max core clock of 830MHz without blinking, but this was nowhere near acceptable.

Thanks to an extremely helpful guide posted up on Legit Reviews we installed Rivatuner and got to overclocking the 4770 seriously...the bloody thing just kept on powering through each clockspeed we threw at it, laughing manically.

With a disbelieving stare we hit our final core and memory speeds - 934MHz core and 839MHz memory! This is a huge 25% core speed increase, achieved on the stock cooler without altering the fan speed at all, which passed 3DMark06 completely stably.

Check out the XFX 4770's GPUz page for more info, and make sure you snap up Issue 102 of Atomic for the full review of this incredibly capable card!

Mmm...4770 in our testbed.

t8y May 19, 2009 5:25 PM	how come reviewers get the good version with the (cool looking!) dual slot cooler, while retailers get the cheaper cards with the dicky little heatsink? xfx are apparantly bringing this one into the country though
RaRaDawg May 19, 2009 7:22 PM	512MB and 1GB version would have different looks I assume.
RaRaDawg May 19, 2009 7:49 PM	No wait...GPUZ says it was 512MB... I dunno whats going on lol.
cleadge May 19, 2009 7:53 PM	omfg.. i may have to pick up one of these hot lil things. The difference between the 512 and 1gb cards would be minimal i would imagine, but i guess we will find out when 1gb versions are released.
Tezlin May 19, 2009 9:31 PM	Is Atomic slipping? What an unprofessional picture. :P
TheFrunj May 19, 2009 10:19 PM	Tezlin, what do you mean? It's a shot of the card in the testbed. Unless it's somehow confusing to test the card outside a case? :P -JR
t8y May 19, 2009 11:47 PM	any chance of testing one of the ones with the cheap little heatsink and comparing the results? id read that not only were the heatsinks different, but the voltage reg chips were too (to cut further on costs), and that reviewers were only given the better version. so im curious if the retail ones will also get 25% overclocks (although my mate has 2 and he cant get squat out of his..)
t8y May 19, 2009 11:48 PM	sorry to double but i know every card is different, rare that one will overclock like another, im just saying.. itd be interesting if there were differences
TheFrunj May 19, 2009 11:51 PM	I'll see what I can do, there's a reference 4770 on the way (supposedly). No promises, I'm already pretty busy with the site and mag, but I'll do my best! -JR
MrPodgy May 19, 2009 11:59 PM	Wonder How this sucker would go on Dice or WATER or Submersion... PLEASE ATOMIC GET A SUBMERSION TANK GOING IN COMPETITION WITH WATER COOLING RIG AND AIR
Elfarch May 20, 2009 12:38 AM	YEAR. Why aren't you testing them in a liquid helium tank? :{p
Kasalal May 20, 2009 7:01 AM	Argh the caps are killing me.
nesquick May 20, 2009 8:06 AM	Nice result Justin, makes my 995/1178 OC on my HD4890 not look that great.
stash May 20, 2009 1:48 PM	Alot of places have these listed but with no stock =( I sadly have my new build sitting here uncompleted cos im waiting on these cards to emerge so i can stick em in cf.
TheFrunj May 20, 2009 2:53 PM	Hey thanks nes! Nice clocks yourself :) -JR
Tezlin May 20, 2009 4:06 PM	Frunj, I meant the traditional white background is gone. :o horror
Hawkeye May 20, 2009 5:39 PM	Heh - that photo was in our labs - nothing white about that room! - DH
OnaZ Jun 23, 2009 10:06 PM	ok if you buy the xfx 4770 choose the YDFC not the YDLC ( the one with the small fan ) cause the one they testing there is the xfx 4770 YDFC with a huge cooler.
moody58 May 10, 2010 8:20 AM	i have my xfx4770 sitting at 900 1000 stable. 3dmark06 score of 12068
