here's my spec...

AMD Althon 64 3200++ Venice
1GB (512x2) Kingston Value Ram DDR400
Coolermaster Extreme Power 380W
Winfast 7800GS @ 475/1420
Asus A8V Deluxe

i tried my processor on my friend's rig before...it's stable even at 2.6ghz...

but i cant even oc 3% with my processor... sometimes wont boot sometimes it crash terribly on the desktop... 3% increment only...

i hope to know what's the problem...

i tried lowering HTT speed to 800mhz, running dual channel at 2T command, 4 burst length for RAM...and the rest of the settings are default...like ram timings...vcore and all...

i hope to get some guide how much should i put for all those...

voltage? what power supply u r using?

do u overclock manually or use the asus % default oc setup...

Cooler Master Extreme Power 380W PSU

default voltage... 1.47V something...

i think 380w psu is not enough..and the ram too..u should use high performance ram such as corsair xms..etc

my friend can oc his amd 64 3000+ (939) from 1.8ghz to 2.6ghz with 450w acbel psu, 2x512mb Corsair XMS(dual channel) and DFI Infinity mobo...
with stock cooler too..

he cant oc b4 with caplang 400w psu and 2x512mb corsair vs ram..

mobo oc-bility also must consider..

i know...but...i cant even do oc as much as 60mhz...

try to gain ur core and ram voltage..just my 2 cents..amd oc-ing is complicated..timing,HTT,command rate..etc.

im not very2 expert in oc..just oc barton b4..quite complicated tho...

wait for more sifu in here to help...

well..happy oc-ing

have u try another bios version??

i think maybe the bios on ur motherboard hang u back as u alrdy test ur proc. on other rig..so maybe u shud try other mobos tht highly overclockable such as dfi biostar etc...ur psu is quite alrite since i can oc my sempron3000 from 1.6 to 2.2ghz only with stock psu n stock cooler..as for ur ram timing u alrdy cover ur base pretty well..

try to OC using manual setting, increase the vcore, ram timing....it is all depends with ur rig......

btw....asus is not really good in manual overclocking.....if u can get DFI...there are many function in there.....

wow 380w psu is too low to oc brother...ur system not stable...last time even i using p4 350w i also kenot boot in with no oc...with ur spec i think better get 450w true power psu before u oc

i'm not sure about that Asus board , but for value RAM you can always use 333mhz divider .
for 7800 , 380w power supply
HTT speed won't affect much even you lower it to 1X

please correct me if there mistake

u need to change ur psu.. get a psu that more stable 12v railing.. try askin' people in this thread for a better psu maybe like silverstone psu

http://forum.lowyat.net/topic/218930

when u tried oc ur proc with ur friend's rig, what ram he used? and have u tried put a divider btween ur ram and proc?

hey, u overclock ur RAM also when u raise the HT lar.....did u lower ur RAM frequency? try it at 166Mhz and see.

i did my humble sempron 2500(default 1.4GHz) + MSI K8MMV(which is the worst overclocking board, trust me), 512MB RAM, guess how much i get?

overclocked ----->>> 2Ghz CPU speed, HT at 286Mhz, and RAM at 444Mhz. the HT multiplier i used is 2. and i max out the RAM voltage at 2.8V. the CPU voltage, HT voltage couldnt be tweaked at all, as i said the worst overclocking board.

by the way, im using my super capalang PSU 300W. PSU should not be ur problem actually.

so thread starter???
what is the result of oc ur PC now??

Well, it's your ram that is holding you behind, my friend using Apacer DDR400 only managed to overclock just 5% faster before the system becomes unstable. You should get a pair of performance ram and a better mobo for better overclocking results.

He said a cooler master psu man...,not chapalang.....

the answer is here: VIA K8T800Pro chipset

answer for????

A8V Deluxe using VIA K8T800Pro chipset. VIA chipset can't clock high.
