same here

lack of practice made me think that assembly is nonsense

who told you that?

you will only burn your rig (not only mobo) if you use
- excessive voltage applied without proper cooling
- using low quality mobo like the generic ones
- cheapo power supply

guys i dont know if this is the right place to ask, but i hope i can get some answers...is Athlon X2 overclocking similar to normal A64?

yes....very similar

Anybody can help me choosing rite mobo..
it's seems that i lost..
i need mobo for AMD64 s939 that is:
- got PCIE gfx slot, i dun wan SLI
- got 4 DDR
- brand either Abit, Asus or DFI
- Budget around RM350 max

depend with ur taste or what r u going to do with ur system dude.. but i think the board with nForce4/ultra chipset would be the better one for sc939.. around that price range u can probably get nForce4 vanilla only.. DFI NF4 Infinity, Abit AN8, ASUS im not sure.. Check out their features and choose which one that will suit u better.. Hope this help..

Can someone help me in doin the right setting for OC.
i only can hit fsb280 stable. that is only at 2.5G. But can't after that.
Amd 3000 Sc939.
HT at 4X
Ram at 166.

Or mayb it is becoz of my ram that can't go higher? Kingston normal ram at 512x2.
but i have samsung chip and kingston. but it can run on Dual channel.

what is the max oc for this mobo (KN8 ultra from abit)?

Help me gurus... i'm a new guy want to learn this exciting ability.

lower your HTT to 3x a
4x280 = 1120
over the 1000 already a.

but it run stable. u mean if i want to go higher? But if the HT is below 1k, does it mean that the performance will be lower? thnks yah

HTT must never be above 1k la abang....zzz

whatever u do, LDT/FSB x fsb = 1000 or less or else your proc may fry..

and please post your specs la if u want ppl to help...

ok i'll send in 2morrow.. gtg now. thanks a lot

This my spec.

Amd 939 3000
Abit KN8 Ultra Nforce4
Value ram from kingston 512x2
Noise Taker 600w Enermax.
HIS x550 128Mb of ram
Dvd-rw and combo.

And now i'm OC to 280fsb
Ht 3x (which is much better in performance)
Normal temp is 29 and 35 at load.
DDRV at 2.7V
Cpu at 1.5
Ram at 166Mhz.

it the setting ok, but how to get higher as it hang if goes more than that.
is it my ram, or mobo. anyone own this type of mobo.?

no setting is ok lah actually when overkloking. mostly overkloker look for highest speed vs. optimum setting vs. stability. from given spec the cpu run with 9x multiplier (280*9=2.5G) & ram at 166MHz. your actual ram speed with this setting is cpu speed/11 that translate into 229MHz (please check this using Everest CPUID for validation). i don't know what ram chip used on your kingston(KVR) but average kvr will not go over 230MHz. lowering the ram speed to 133 and setting the nforce voltage around 1.6v will help u gain higher fsb.

i guess you know what tools/application needed to check & monitor your system while overkloking the cpu but i do recommend you read and learn alot about your components espescially cpu, cooling and ram timing.

really? im running on 310x9 at 4x HTT . so far i havent got any weird readings?

hehehe there you go. nothing happen ah to your system with that htt speed? from what i've read here
the htt clock speed operates from 200MHz to 1.4 GHz range. i think that's why u havent got any weirdo happening to your system. as far as i understand the amd cpu/system that "support xxxxMHz htt" may utilise the htt bus bandwidth at max with that given supported speed but not any further. it's still not a problem if u run the htt at any speed below 1.4GHz. the factor u must consider when running high htt speed is the LVDS IC that come with the motherboard (if u know lah which manufacturer produced the LVDS IC for your mobo). u may read more about LVDS here

PowerHouse im using NEARLY the same specs as yours
but how ah if im using AMD Engineering Test Sample A64 3200+
how to deal the fsb?sorry ah quite noob in oc

from what i heard and read,
Asus : quite stable but limited o/c capabilities
DFI : picky on value RAMs
Abit : not very stable, bad reputations..
MSI : many forumers told me to avoid MSI..

if i'm going to o/c a bit..
what mobo u all gonna recommend me..?
my rig that i wanna build;
pro : AMD64 3000+ Venice
mobo : still not decide yet
RAM : 512*2 Kingston KVR DT-D43
PSU : CM Real 450w
Graphic card : ATI X1600XT

since the topic is A64 OC , i got a question here.
Currently running at 233htt with 1:1 using 3000+ venice, DFi Infini SLi and KVR 512mb x 2.

The prob is when i'm primming, it gave out an error in calculation


when i increased the vcore voltage to 1.48v, around test 7, the error will popup or even in test 1 it'll popup too. then I finally upped the vcore to 1.5v and primed till test 10, no error so far. I didn't prime for long though, around 30-45 mins.


What say you guys on the whole thing? Should i increase the vcore again or the ddr voltage or the nf4 chipset voltage? i only tweak with the vcore and nothing else so far.

hmm...for kvr rams, recommended to set to 2.8v if you intend to oc....and as far as increasing your chipset voltage, you only do that if you find that your system is unable to perform well at very high fsb (more than 300mhz)...other than that, increase the vcore slowly to determine the max possible clockspeed for your processor

I didn't increase the clockspeed (set at 233) while increasing my vcore.
vdimm at 2.8? will try it out
