Got conflict with the bios and the oc guru..If Setting in bios, cpu-z still show the default settings.. Need to uninstall the oc guru? Better use oc guru or manual?

I run mine with 280mhz @ 2.7v rite now. Will try to increase the mhz till 300mhz and see how it goes.

Put a 80mm fan above it, that would do it.

Have u turned off the Cool 'n' Quite at the bios ?

i sold off my tccd d.. nw using infineon ce-5 1gb x2... running at ddr400 2-3-2-5.. quite nice, i oc my opteron using divider and low timings..

my TCCD running daily at 2.83V @ DDR640 (320MHz@3-4-4-8)

Ya.. Wan oc must turn off maa..

U see the pic.. dunddo which one is the true freq.. cpuz only detect the right ram setting but not the cpu freq..

thanks..finally my ram can work at 240mhz at 8,4,4,3..up the max async latency from 6 to 7 n it works..tested with no errors..but is there anyway to run test with memtest?it seems that it only works when i logon to windows..i currently stress it using prime95 n rightmarkmem test..btw, mine is UCCC ram..usually what's the highest voltage n speed it can go?

There is DOS based memtest called Memtest86+. You can copy it to your bootdisk and run through DOS.

Mine cant even post at CL3. Mind to share your A64 Tweaker setting ?

ram dah rosak kot

ok, here's mine...

yeah i do have memtest86..however i'd like to know if the setting i use in windows environment can be applied in memtest86..because in a64 it only loads up during start up..i adjusted the max async by a64 coz if i dont i'll fail prime95..n my bios setting does not support this tweak..how ah ..or izit otomatically changed the bios setting??

I just can hit 2.4 stable.. Wan to make it faster.. try to push faster but not stable..
Any sifu help me try hit faster freq...

give more voltage....simple

u see it show 1.35 volt rite.. but in bios it is 1.425 oredi..
Thinking of the ram not that stable timming.. maybe need to set divider..

memtest86+ has the option to change the common timing set during the testing, but other stuffs such as async latency or preamble thingy is not available if i'm not mistaken.

a64tweaker doesn't have any effect to the timings before u get into windows.

here's my screenie on my first OC attempt




OF course, i do have some question as noob always do

1) I cant get it running at more than 245Mhz bus speed...what's holding me back rite now

2) It's freakin hot ... i'm thingking of lowering down the VCore but the lowest posible option was 1.40. I've seen some people lowering it to 1.36 ... how is this possible

3) anything wrong in those screenie ??

i'm sorry to bug in, mod did this

1. Assuming u have already decreased the LDT multi to 3X, i suggest u try to decrease your cpu multiplier, n then try increase the bus speed (if you can, try setting the ram to its default speed n timing). If u succeed to increase the bus speed, then most probably it's your cpu limiting you..

2.What hsf are you using? If u're still on stock HSF, then around 50C on load is considered normal to me, not hot. If you still insist on lowering the heat, change the hsf. Some people are able to lower their Vcore to 1.36 probably because their CPU is able to do so (some Athlon64s are rated at 1.40V while some are rated at 1.35V), or maybe its because their mobo,or probably just some voltage fluctuation.

When I OC my rig I realise I really need to pump a lot of voltage to my CPU. Kinda weird I need to set the voltage to 1.65v to get my rig stable at 2.4ghz when I check most DFI mobo users require only around 1.4v to get around 2.5ghz. Guess it differs for every motherboard.



Anyway here's a screenie of my 2.4ghz OC set up with a Athlon 64 +3000. I'm waiting for my Ultra-90 HSF(currently on stock HSF) to arrive before I attempt to go higher.

Btw wats the highest voltage I can pump to my BH-6 chip?

mxxuang, u're right there, and i wanna add that it differs for every cpu also.1.65v @ 2.4Ghz is high indeed..that amount of voltage is enough for me to get my venice running @ 2.7Ghz, and maybe 2.8~3.0Ghz for some other ppl.

bh-6?i think max 3.5~3.6v..(correct me if i'm wrong..)

But when I set the voltage to 1.6v I can't even get my my Prime95 stable for even 1 hour. 1.625v is fine, but I set to 1.65 to be on the safe side.
