edit, more german craziness now with a VF1000

ah, didnt flash the card, new ati drivers fixed my instability problems.

wtf at the oc power consumption btw...


I get 870MHz before lockup, without any artefacts or such...seems like the power regs simply cuts off at that frequency.

I say, the card certainly dissipates heat...I think I will make me some heatsinks for the mosfets. Maybe that will stabilize things a bit.

The powerconsumption when OC seems insane, makes me wonder what my card pulls @1GHz/1.2GHz??

hi has anyone tried fitting an after market Zalman VF900 on to one of these? the zalman website doesn't say anything about it.

im planning to buy a sapphire 4770, and transplanting my VF900 onto if it can fit and also if it will cooler better/more silently.

I asked myself the same question. I googled around and found one forum post (no link sorry) stating it was possible. However there was no pic.
Guess one of us will eventually have to try and post results :)

yea me too. i think i might have seen the same one. but not enough evidence for me to make the decision as yet. guess i could signup and message them to find out.

Just got mine [a 4770] today. Haven't done any overclocking or benching yet other than 3dmark06 where it got 12320, which obviously is just a synthetic benchmark and a dated one at that. Mostly just used it to see the temp. According to GPU-Z idle temp was around 32C and load was around 41C with my trusty zalman vf900. Guess I shouldve taken a temp reading with the stock cooler first...


btw i saw a VF900 on the very first page of this thread, however i can't quite tell exactly if it is a modified version since its only a preview/review sample.

surely must be someone else out there?

did some further digging. these images came from non english sites ... but they look like 4770s :D

As long as the cooler has mounting holes with 43,5 mm distance (square) it will fit all right.
I fooled around with a redundant Zalman ripped from some dead 8800GT - drilled holes, fitted some bolts & spacers and voila.
The contraption cools barely better than the stock cooler, even tho it sports 2 pipes. A better option in this case would be just to flash & mode the card's BIOS to allow the fan to go below the stock 32%, say - down to 27% or 28%. Temps suffer just a wee bit but the card is then practically silent.

Of cours the ultimate way to go is to just slap AC S1 Rev. 2 on the card and simply forget about it. That is - make sure at least some ventilation is present. That said - I have a pictorial ready on 4770 & AC S1, I'll post it soon.

just curious if anyone has tried the non-reference xfx 4770. I'm wondering if the idle power consumption is better?

I saw a review of that one recently (sorry, I don't have a link), and the idle power consumption was identical to the reference card.

I would ask the same question of the newer Sapphire 4770, which has both a non-reference cooler and a non-reference PCB layout.

if the Bit-Tech review is to be trusted, then the card might be decent on idle power.

That's the one I saw. If you look at the X-bit labs numbers for the 4830 and note that Bit-tech show the 4770 as using 10W less, that suggests that they are getting ~22W idle from it, which is more than the 17W that X-bit labs got, but less than the 28W measured by SPCR, and a lot less than the 37W I've seen on a number of other sites. There's probably a lot of error working it out like that though.

Now I just need to see one for the Sapphire card...

EDIT: Found a review of the Sapphire card, which shows idle power consumption for the whole system, and compares it to a 4890. Going back to X-bit labs' numbers and assuming that the 4890 that Tweaktown use has the same idle power consumption, that gives ~18W idle. It sounds reasonable, but the numbers from 4770 reviews are all over the place so it's impossible to tell if it's as good as the reference card without a direct comparison.

if either of the cards idle around 20W, I'd grab them in a heartbeat. might wait a bit for the launch of the 5000 series, and maybe some price drops.

I went ahead and purchased the aforementioned Sapphire 4770. With the 4770, my system idles at 87W AC, compared to 78W with my 8600GTS. X-bit labs measured 21W idle for an 8600GTS, which would put the Sapphire at ~29W. However, my 8600GTS is a passive MSI one, which might well have different idle power. Either way it's not as good as I had hoped, but acceptable.

The fan is pretty quiet too. It is not audibly any louder than the passive card I had in there before.

EDIT: I take back what I said about the noise. I wasn't stressing the card enough to ramp the fan up (games are severely CPU limited now, luckily I'm upgrading soon). When loaded fully, the fan emits an annoying whine. It's not particularly loud, but it is precisely the wrong pitch.

I thought about getting the 4770 for my HTPC setup, but got a 4670 instead. It's just too up in the air what the real idle consumption is. It might be that it varies from card to card - unless it's a reference card. Maybe in the next PCB revision they will remove the auxiliary power connector or is that the 5670?

If I got it well, the problem is that you cannot underclock gpu and ddr5 as I usually do with my hd3850 (125/200@0.9), right?

the accelero r2 seems to be hackable in all the atis, I got one two bolted on to a ati 2600 agp, now going to a 3650 (which is smaller than the 3650..look close at ati numbering, the past may just be bigger than the the present "biggest and baddest") The 2600 had 390million transistors, heatsinked top and bottom and used a large pcb wieghing in more than any card in my 10 years of ATI...the 3650 is claiming 55nm process and not needing as much room, on 378million transistors. I know losing the 2600 pro is a bigger loss, pun intended. no ati will ever use the fan peacefully EVER. not even an 80mm case fan stays at peace with these chips. they are riding changes fast..with number games and no real changes from the beginning of the rv600+ to today. Do doubt all oe cooling..seriously. luckily for you the fan got annoying right away...time for a change before it commits ATI suicide....
