** Official ATI 5770 Thread **

Can someone do a step by step for shroud cooler removal and thermal paste change? Pictures would be ace.

I asked this question in this thread and bhavv gives a description and a link over to XS. took about 30 secs to get the shroud of while being carefull maybe another 5 min to change the paste...mx3 knocked approx 10c of load temps
 
hi, if the postman doesnt get blown of the road and if he can get through the floods i should have my 5770 soon :) Now whats best way to remove nvidia of my comp ?
Do i uninstall with nvidia's uninstall then run this driversweep thing i hear about or do i just use driver sweep to start with and not both with nvidia's uninstall prog?

How do you spread the MX-3? The all over thin layer method or the stick a small blob in the middle and rely on compression method?

I used two small blobs in the middle because the chip is rectangular, then rely on compression.

I had asus paste, but it looks the same as MX3, thick, gray and blue tac like.

I made a guide on XS, but cant link it atm as Im on my phone.

To remove the shroud cooler, its the 4 small screws around the core, then you need thermal paste remover and MX3.

Always remove and reinsert the screws diagonally to even the pressure on the chip, and dont overtighten them.

Well i think i have sorted the 2D Crashing after a lot of delving and research. The issue seems to be that on idle the gpu drops the core frequency down to 157mhz which then causes the memory to throw a wobbler and crash. Just create a profile in CCC then manually edit it so the idle speed is 400mhz and the memory is 1200Mhz and it seems to work a treat. Ok it will possibly use a tiny bit more juice but i will take that over crashing and driver not responding. :D

The 5800s seem to suffer the thing, problems at low clock speeds when idling on desktop.
Another way to get the idle 400/1200 clocks is to connect your monitor with 2 connections (if it supports this) say dvi and vga or dvi and hdmi. Then set them as duplicates in CCC. The graphics card thinks you have 2 monitors connected so uses the 400/1200 clocks. Downside is it reverts to 157/300 if you overclock (another bug they havent fixed yet) but it is an easy way to see if you have low clock stability problems when you dont have 2 monitors to connect.

To clarify this not a bug its ATI power play is is mean to happen expect no fix. I have fixed mine with a driver update. 5 hours no crash or disply error so far
 
What stable overclocks are people getting on this card atm? I can only get it to 930/1300, anymore then driver crashes etc. Still it gets me 250 more in 3dmark..

You need to use MSI afterburner to increase the voltage to go higher on the core.

I believe that the samsung ram is only capable of going to around 1300 Mhz, while a lot of people with Hynix have been able to max out at 1445 based on results from XS.

Ohh right. Mine must be the other memory then. I already flashed the card and anything over 1300 it doesnt like.
Ill might try the gpu clock abit more
 
Its worth benchmarking at fairly small intervals when overclocking the memory. It has built in error-detection/retransmission but this hits performance when it kicks in, so what you'll find is performance actually drops at some point as you increase the memory clock. My hynix memory drops performance from 1360 to 1380. From 1400 thro 1445 it picks up again and beats the performance at 1360. Also benchmarking seems OK over 1360 but games will lock up at this level for me.
 
Anyone have some temperature results for two of the egg cooled ones running in crossfire at 1000 Mhz?

It would nice to see if they are better than my shroud cooler results:

This is why I bought new coolers for mine. They needed to be set far too loud to keep the temps below 90 degrees.
 
i just got a pair of these, the vtx3d brand, and i must say im highly impressed. firstly the vtx3d come with the full shroud cooler which looks much better than the egg shaped coolers, they expel the heat out of the case than keeping it all in, and secondly they come with the hynix memory, ive been having a play with my card and they clock pretty good, 950/1430 without any mods, they run pretty cool too

heres some results and pics:

ive not even tried a game yet lol

might try flashing them to the asus bios but let me have a few days before i destroy them lol
 
Well i recieved my 5770's today :) Really impressed with them so far. Im averaging around 85-90fps in NFS Shift and 60fps+ in COD modern warfare2.
This is around 20-30 fps more than my 4890, so all good and Remarkably quiet too:)
I also ran 3d mark 06 with standard clocks and hit nearly 24k:D

I




BTW when i try overclocking them, i cant get them past 840/1240 without the screen tearing or the drivers crashing.
I then tryed with one of them i can get it to 900/1300:confused:
I think it may be the other card? RMA perhaps:confused:
 
rma because it doesn't clock that well :eek:, love to see how that would work :p

what power supply are you using? also what memory do you have on your card, hiynx or sammy (i think)

I've got a corsair HX850 watt, more than plenty.. Dont know what memory but i presume the one that doesnt overclock so well? One of the cards is the asus with the voltage tweak as standard and the other a sapphire from here
 
yeah power supply is ace, i have the corsair 750tx myself, the hyinx memory is the one that clocks well

i personally would have got the same matched cards tbh, anyway lets install some games now :p
 
I game at 1920x1200 currently with a GTX260 216sp.

Now i dont think the 260 is struggling at all, just played MW2 maxxed out but i fancy a change as i havent had an ATI card since i had an X1800XT years back.

Im thinking of buying a 5770 now then asking the wife for a 2nd one for xmas. Would a pair of these be much of an improvement. Ive never used crossfire before as ive always had SLI setups.

Lastly will my Corsair 750W PSU handle a pair of 5770s? It coped with a pair of 8800GTX's if that helps :p
