Errr what i mean is using riva tuner + plugin to control voltera pwm,not bios vmod

juz wanna ask.. izit once oc.. the warrant is void?

Nope. You still can warranty provided there is no burn mark.

-pWs-

erm... by right, no ... but usually they close 1 eye, as long there's no burn mark on the card, they will still accept rma... otherwise customer not happy ma

I dun blame anybody bcoz its my own choice to play around

anyway, everyone's a noobie from start

I dun wanna b a noobie forever dats y i opted to try.....found out this winflash does hav some probs to work with Palit Sonic hd4850, other boards i dunno la, but from the infos i read, works well with most reference boards

FYI, my motherboard has no 2x PCIE or onboard, so I borrowed a PCI vga card from a Pentium classic.....re flash ori bios with ATIflash (dos), startup using USB stick go into DOS, flash it with command 'atiflash -p 0 newbios.bin'

i fixed the prob with zero cost and my sonic hd4850 now back to normal...

in case anybody needs help, PM me, i'll try my best to help

mind telling us exactly how u tweak ur card with rbe?

hi..

wanna ask..
my 4850 can use this cooler or not?

Re:OEM Zalman VF1050 4-Heatpipe VGA Cooler

i followed the Techpowerup guide n i jz tried again yst; I loaded my previous bios into RBE, nvr change a single setting, try flashing it....then it says bad checksum cant flash somthing liddat....

even if i acquire my own bios n reflash oso same error msg came out, so i knew i shudnt proceed or i'll end up bricking it (again)

i see.... well, try this if u dun mind

1. overclock using ati overdrive
2. go to profile manager and save the profile
3. go to C:\Users\<username>\AppData\Local\ATI\ACE\Profiles if ure using vista, xp go to C:\Documents and Settings\<username>\AppData\Local\ATI\ACE\Profiles if not mistaken
4. open the .xml file using notepad

u should see something like this:

do it at your own risk

core clock higher is better, mem wont give you so much boost also

There, your card is not a reference version in the first place. That's the thing that caused all the problems

oh kay am way interested in learning how to boost this card

what did you guys do from a - z =D

will get an e8400 or q9400 processor soon coz my d820 is definitely bottlenecking it

wat do u think bout the processor too?

am running it at default which is 625 1004

my card is not reference card as well, but i was able to mod bios @@... suspect something wrong in the settings he made

i know bout this already.... google "vmod without risk" n read it from another forum

anyway thks for ur help, mayb i'll attempt pencil mod 1 day....

Recently, I got problem with my Gigabyte 4850. My PC cant boot UP and sometimes got corrupted display in bios. BTW, I'm doing bios mod.

Izzit something wrong with my GPU? Broken?

Anybody here can help? Thanks in advance.

juz asking... this HD 4850... OC to 750 mhz n 1050 mem clock... idle 40C ok wif the temp?

You update BIOS or ? Try roll back previous BIOS see can boot up or not...

Ya, maybe he choosed the wrong bios for his card lol

corrupted bios eh try to flash back the original bios and see if the problem is still there or not.

tested stable with furmark ?

I've been thinking also the bios corrupted. But since I'm still outstation, can't do anything. It happened when my sister try to boot up my PC.

Anyway thanks for your insight.
