wat clocks can you hold for benching ?
im currently testing
to the max
So i received my 5770 yesterday and i am happy with the upgrade from my 4850, alot cooler and better performance overall.
There is 1 thing i dont understand though, It seems like i can't overlock my card at all, I did an auto-tune in the Catalyst overdrive which gave me about 950/1400 but once i started any games my pc froze and i had to reset. I kept underclocking it but it seems i cant get past the default clocks 850/1200.
Same thing happened with my 4850 so i was wondering if i was doing something wrong since most people can max their 5770 in the ATI overdrive with no problem.
here is my spec:
System Manufacturer: Gigabyte Technology Co., Ltd.
System Model: GA-MA790X-UD4P
BIOS: Award Modular BIOS v6.00PG
Processor: AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz
Memory: 4094MB RAM
GPU: Gigabyte HD 5770
Start small, set your clocks to 900/1300 and do some testing...
Flashed to ASUS BIOS
Core Voltage 1.200
Core Clock 1000mhz
Mem Clock 1350mhz
Using MSI Afterburner
Where is the ASUS tweak panel ? Link anyone ?
you should try dling msi afterburner from guru3d. its a lot better than the ati overdrive app and allows monitoring of temps, gpu usage, fan speed, etc. and has datalogging capabilities. and, short of living in a european winter, 1400 on the memory may be a bit much. if you look on the card, you'll notice the memory chips on the back of the card have no heatsink, whereas the memory chips on the front are thermaltaped to the heatsink/heatspreader. they get hot pretty fast. even with a well ventilated case (5case fans in mine), they still get hot.
dl furmark, run the stability test in a 640x480 window. slowly crank your clocks up in afterburner by 20mhz each time from default clocks. and let it run for about a minute or two each time. adjust core clock alone until it starts to artifact, back off about 10-20mhz from the point of artifacting, then do memory until it artifacts. this way you can monitor the stability of overclocking.
also, what brand of 5770 are you using?
Thanks for the help, the result is 940/1320. Anything past 950/1340 crash my computer:3eyes:
my 5770 is a gigabyte.
I put heatsinks on the back of my 5770s and got 30mhz more out of the RAM.
Im sure I have downloaded the ASUS overclocking utility for the 5770 in the past, does anyone know where I can get it again plz?
Dont worry, found it here
Nice flashed the card nice and smooth :thumbup:
hehe i got decent gpu score with this oc
Best thing with unlocked bios is that you dont loose power play when overclocking :banana:
Nice score... Now go buy Happy's i5 750 and P55-UD4!!!!!!
You know you want to...
Yeah man powerplays the shizzle when it work lol
and i wish i had some cash maybe soon though hehe
your jealous now
wow man i need to aim higher lol
what kind of voltage you using ?
