owh that...
normally, when overclocking in windows (not sure in BIOS though - but my PCI locked), increasing FSB, might as well increasing PCI bus, not too sure why's that, but it happens, so, by using ClockGen, uncheck "Ignore GSB/PCI", and you should be able overclock without worrying about PCI bus anymore...

if i'm not mistaken, that your problem, you can't go beyond 239MHz right, and from what my bro XP, just like i said previous post, just set it to 250 or watever you can get, (sure it won't boot), just hard reboot, hold "Insert" key while pressing power on button, this will bring you into boot-safe option, but still your BIOS is at 250 now, just hit F1 "Continue Anyway" and you should be able to run Windows...

Is anyone using mobo asus A8R-MVP here?

i've got problem when i oc wit this board...

well.. i tried both hard and soft rebooting when you last told me to and it still didn't work. Windows just refused to boot up.

anyway, downloaded the latest version of ClockGen. i've already checked the GSB/PCI tick-box.. so will try it out later to see if it actually works..

why not tell us ya problem & list out details of ya rig here?

in general, d board is known to have voltage fluctuation & 1t issue for some modules...

have some read here:

what is hypertransport voltage?
i just manage to OC my amd 3000+ from 1.8 to 2.0Ghz only (9x X 221)

on the BIOS screen, i can see hypertransport voltage (2%,4%,6%)
default is 0%, can i up it a bit? ...like 2% or 4%?
and i go up the clock again?

Added on March 13, 2007, 4:10 pmno wonder la...after i read from others site review and forums, it seems that this mobo can't support to OC dual core processor.. I'm using X2 +3800 on this board, and whenever i try to OC a bit, even to 2.2Ghz, after 5 minutes it will restart again and reset..

has anybody using this mobo also? how to solve this prob?
i would like to flash the bios, but afraid to damage my rig...

Just wanted to know, is it we can determine how good a processor in OC by what stepping it use?

I have an Athlon64 3000 lying around and maybe use it to learn how to OC with it. The stepping is LBBWE and E6 Venice.Around how much it can be OCed?

this has been said many times, ocing cannot be determined by anything except ur luck. no1 can ever tell u how much u can oc and all that

up voltage only when instable occurs
remember to lower HTT multiplier to 4X / 3X


i hate this kind of question actually
http://www.amdgeeks.net/steppings/ADA3000DAA4BW
google yourself

hmm, if i lower HTT multiplier to 4X, then i must do the clock from 200 to 500 right? in order to get 2GHz.

default for my proc is 200 and 9x=1.8Ghz

i can only do it to 220 and 9x which makes up to 2Ghz
last night i tried to lower it to 8x and increase the clock to 250 to get same result of 2Ghz but the system hang at boots up. so i need to reset the CMOS.

i use HTT x1 , even at stock, HTT Multiplier set at 1x , no harm done anyway...

i dun understand....
u use 1x? then how much is ur processor speed? how much is ur clock?

i mean i lower the HTT, then why i cant get 2Ghz and better?

from the pix i uploaded, i use HTT 2x instead of 1x, IMO, there's no slight improvement nor instability issue if use 1x or 4x, it's just make sure, you're not exceeding 2000MHz barrier...reason - not too sure...

[DFI LanParty nForce4 SLI-DR @323x9] + [AMD64 Athlon 3000+ @2.9GHz]

gosh how did u manage that?
u use special fan or stock fan?
u got adjust ram timmings?


umm.BTW did u use window vista? if u do, how much is ur score?

i used to have 2x512MB Team Extreme DDR600, and i use 1:1, the RAM can go all the way DDR666 without BSOD while booting up, but failed on every stress test , however, i primed >8hrs with DDR640 with 1:1 @3-4-4-8 @2.87vDIMM, that's for RAM, and for CPU, yeah...my CPU capable to do 3.0GHz @stock vCORE, successfully boot to windows, but failed on every stress too though...primed stable at 2.9GHz also at stock vCORE, i did increase the vCORE see what happen, same...it won't help , for cooling solution, i use ThermalTake Big Typhoon (idle @26�C while; load @38�C)
i'm not that pro in finding good timings, so i only set it to loose timing for more headroom or tight timing .

the mobo capable to do 440FSB (that's the highest FSB it can go)...of course, when finding mobo highest FSB la...so, short word...

CPU @2.9GHz; 1.376vCORE; 323x9 (primed stable)
Mobo @323MHz FSB
RAM @DDR640; 3-4-4-8; 2.87vDIMM (Team Extreme Hermes DDR600 PC4800)

Overclocking with 2x1GB Aeneon PC3200 DDR400
i've got myself this RAM module, after doing some "research" bout this RAM and i found this RAM is good i must say...FYI, i'm running on DDR533 (stable) @3-4-4-8; 2.87vDIMM, the post @other thread, i posted that i managed to get DDR550, but failed . anyway...now running in 9:11 divider)

you miss-understood , a lot

ok , HTT multiplier is got nothing to do with processor speed .
HTT multiplier (1X to 5X) is different from processor multiplier ( for A64 3000+ , 1X to 9X )
as far as i know , HTT is the internal connection between chipset components and the processor

example :
your HTT speed can be as low as 300MHz when CPU speed at 2700MHz
( HTT : 300 X 1 ) / ( CPU : 300 X 9 )

oic, u get it right.
yeah stupid me, i tot HTT = processor multiplier
my processor multiplier is 9x, and i dun have to drop it any lower right?

so right now, it is 220 X 9x = 2Ghz
i cant get it any higher etc. 225 X 9x becos the system boot will hang.

so i need to adjust the HTT higher or lower? BTW i got up the vcore 1 notch already.

okeh...if you want to test how far your CPU can go, it's easy, lower your CPU multiplier say 4x and try increase your CPU FSB (200MHz by default right)...

proper way of bios flashin wun harm ya pc, so stop worryin it will kill ya board. one of d way to test d max speed of ya chip is to disable cpc for ya ram, since d board have 1t issue with sum modules. btw, wats d steppin of ya dually? my 0614wpmw is doin quite well, but of course i did it on dfi.

i still can't. just tried just now. i've checked the "Ignore GSB/PCI" check box and then proceeded to reboot my pc.

changed it to 250mhz, can't even past memory test..

left it there for almost 2 hours and no progress..

how?
