looking at these results you lot are showing how many are running an amd cpu ? , seems the later intel cpu's are the best for benching yes ? . but how better are they compaired to the fastest phenom II's ? , so you need a fast cpu to get the best out of these gfx cards ? , i was told dont be stupid at guru3d's forum but then i said why do all the reviewers use the fastest intel cpu's overclocked instead of the fastest phenom's ? . some of these results put my cf 5770's score to shame lol

That is a CPU comparison with the 5870s.

I have reached 18000+ vantage points too with my 5770s and CPU overclocked, while getting around 14k at stock frequencies. They really seem to like overclocking.
 
HA HA no mate i cant remember the exact speeds think it was 1010/1310 1.25v however one thing i did find is these cards do not always crash or artifact before the performance goes down. some people that run 1400+ mem will find that my 1310 will bench and perform far higher just like the i7's there is defo a sweet spot rather then faster the better. Took me a week of benching to find my sweet spot.

Yes! You're spot on there.

I upped my Memory from 1300 to 1400 and noticed that I got less performance in Vantage, so its back down to 1300 for me :p
 
I belive to see gains of over the 1300 (ish) performance you need to push 1450+ to see a tiny gain i would say defo not worth running mem at these speeds for so little gain :)

Ha Ha, you cheeky little numpty

, you kept that information quiet didn't you :p

just tried at 1000/1300 and get 18377 marks, and 17055 gpu marks

bah I have to redo the bencies again

cheers for bringing it up BigBruiserAl

I didn't know about it until Big Bruiser said it!! haha, I remember hearing that the 5850 Series GPUs did it and had a small suspicition that the 5770s might do it aswell :p

Oh.. Nice score ;)

Time to sell my E8400 and get a decent clocking Q6600
 
lol

so it seems there's some throttling going on, is it temperature, or like overspeed protection of some sort! a bios hack is needed

I feel dirty and cheated, time to sell these now :o

Its memory correction IIRC, I'll have to find you a link explaining it ;)

EDIT - Here you go buddy!

As mentioned in the HD 5870 article, overclocking the memory on these cards is quite different from any other card so far. Normally you'd expect rendering errors or crashes, but not with these cards. Thanks to the new error correction algorithm in the memory controller, every memory error is just retransmitted until everything is fine. So once you exceed the "stable" clock frequency, memory errors will appear more often, get retransmitted, but the rendered output will still look perfectly fine. The only difference is that performance drops, the further you increase the clocks, the lower the performance gets. As a result a normal "artifact scanning" approach to memory overclocking on the HD 5800 Series will not work. You have to manually increase the clocks and observe the framerate until you find the point where performance drops.

Got one of these arriving tomorrow to replace my ageing x1650, any advice for the install (wait for new drivers on wed?)?
 
Normaly i would just say install them but with trouble i had with the drivers i really would advise waiting until wed if you can ... if they dont come out just grab the ones from the site as normal.
 
Guys,

Just fitted a vapor-x version in the wife's PC which I'm building her for Christmas, which I selected after I found the original XFX reference design 'shroud' was too loud. She wanted a quiet PC, and I don't think the v1 cooler really fits the bill. The vapor-x version is definitely worth the extra though as it's practically silent in comparison.

I've got 2 5770's in mine with the shroud and never hear em?!?!
 
This is true. I setup my PC to be extremely quiet - At idle it's barely a whisper and you can arguably not tell whether it's actually on or off at times.
 
dont think so, 90c is still well within specs for the cards, whip the 4 screws off on the back holding the gpu cooelr on and clean/reapply decent TIM, should sort that out. :)

also, why does everyone hate the egg coolers? iv got 1 of each, the egg cooler runs quieter, cools better and you can hardly see em in the case lol, my big ass cooler got chucked in the bits box as soon as it arrived lol!
