AMD64 3000+ venice overclocking advice

taktmobiles · 16 May 2006 at 14:20

here is my main components

PSU 480W Tagan 2Force TG480-U22 SLi U-Quiet 21db
Chip AMD Athlon 64 3000+ venice 90nm socket 939 ( with original cooler )
M/board Gigabyte K8NSC/939 built in Gforce
NVIDIA GeForce4 MX 440 with AGP8X
1 Gig of geil ddr ram ( 2x512mb 400mhz cl3 pc3200)

current idle temp 30c

anyone give me a rough idea of a safe and stable overclock for the above setup

before i try my first overclock i`d like to know what is a safe boundery guide don`t want to push it to crazy limits just a decent stable clock.

Plus is it best to overclock via bios or could i just do it via the EasyTune4 program in my taskbar.

thanks in advance

WOW

thanks for the initial replays..

gonna have a read of the ram timings see if i can understand that before i start the tweaking,

but obviously i won`t be taking it too high as i`m only running the original cpu cooler

@ !n$oMniA
when i run cpu-z it show exactly the same processor info as yours exactly to the letter

obviously the only thing thats different is the clocks section,

well so far

from 9x 200
to 9x 234

giving me a speed of 2105.83mhz

temp under idle use 31/32c
under prime95 test 43/45c

on first Torture Test under prime95 in just under an hour it errored

FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.

so i upped the ram volt from 2.5 to 2.6 after searching on here on the error

so on second Torture Test run of prime its gone 4hours without errrors and still going

not altered the memory except upping the volt by .1 as the prime error looked to be memory related after searching the forum about the error
but looking on the memory page on CPU-Z its showing does it look ok without altering

frequency 234.0mhz
FSB.DRAM CPU/9
CAS# latency 2.5 clocks
RAS# to CAS# Delay 4 clocks
Cycle time (Tras ) 6 clocks
Bank cycle Time (Trc) 11 clocks
DRAM idle Timer 16 clocks

so, so far it looks as if i`m heading in the right direction, will try and find out the stepping

Did try taking the speed upto 2.2ghz but temp went upto 40c on idle so will need to change from original cpu cooler

cheers Mikebert4

just been looking in my bios theres no options for changing ram timings / dividers

will have a look to see if a motherboard update will give me more options

right,

just done a bios update it was on firmware f1 its now on f8

its now given me heaps more tweaking options in the bios

i now have the option for altering everything to do with the ram and htt

heaps of options are now available where as on old firmware wasn`t there

so off to see if i can fine tune a bit more, after reading the above great advice

heres a little update

above i had a idle heat jump to 40c on idle when trying 2.2

but now after bios update got the following

2205.00mhz

multiplier x9
htt 245
htx3
ram set to 2/1.66
timings NOT CHANGED
vcore NOT CHANGED

temp on idle 31/32c
under prime95 43/45c

ran prime95 understress for 12hrs no errors

------------------
so just upped to my next step

htt 255 = 2301.11mhz

temp on idle is currently sitting at 32c

nothing else from above changed

now time to prime95 on new setting

update on 2301.11mhz pc shuts down then restarts within 10 mins of running prime95

off to read some more on the forum for a cure
