isn't that a lil too high? so 2.5-4-4-8 and 2.9v (2.85 possible? takut burn lah ), then 250mhz*9?

@-vip3rleon9-

try 3-3-3-8 and 2.7v first. if still cannot,try upping the Vdimm. my silly twin stick of rebranded ddr333 KVR can easily do ddr480 at 3-4-4-8-2T 2.9v (didn't dare go higher )

so far i'm running 2.5-3-3-8 @ default V @ DDR470.

i'll try using this timings and OC till DDR480 or even maybe DDR500 on 2.9V.

no need to oc ur ram la.. used timing enought edi maaa... see ur proc first before ur fried ur ram lorrrr

ok. i just found out that my mobo only allows me to locate 2.85V max to my rams. how?

tried both 2.5-3-3-8 and 3-3-3-8 and both stil won't allow my pc to boot Windows properly.

the seller of the DT-D43's, a friend of mine, said he managed to OC it till about 270mhz. but i forgot what proc he was on, would be 775.

why not use bios?
if use bios to OC does it also raise the PCI bus??
not right?

Hey can you unlock 5X HTT link in your BIOS (NForce4 4X chipset). if you can you can refer to this http://forum.lowyat.net/topic/455781/latest on how to unlock 2000MT/s (1GHz HTT Link).
Make sure you have an NForce4 4X chip revision A3 or later.

harlo, does anyone know whats the best clock for amd3000+ venice?
using amd64 3000+ venice, 2 x 512 kvr ddr400, gigabyte GA-K8NSC939 (latest BIOS), winfast 6600GT AGP.

currently clock at @2.33
HT multiple 3x
HT speed 290Mhz
CPU vol 1.65v
CPU multiple 8x

ram timing i set at auto wor, fsb/ram ratio = 2/1.33 if not mistaken
sifus here pls give some comment

ya, s939 x2 still available at bulk section, regret to get my opty last time cause more expensive and sommore get the worst steppings, ccbwe 0551 vpmw... saw those x2 at bulk section can oc till 2.7ghz++, although its 512kb cache, i think its clockspeed tht matters in amd cpu, the cache should made real little diff... am i right?

so, i see that my vcore actually shoots up on load.
how do i make it to have lower margin of difference compared to idle?
cooling the pwm & mosfets only make it less fluctuate, but the difference is still there at load (1.46) & idle (1.42).
this is bcoz i can run lower vcore (1.42) at load, but from load to idle, the vcore will drop significantly making proc not receiving enough juice --> hang =__="
*my other rails are stable at rated value.

Now i got 2 mobo.

GA-K8NF-9 (Rev 1.x)
-AND-
Abit KN8

I wanna oc my AMD Athlon64 X2 3800+ s939. Which one is more suitable for me to oc and which one is more oc-able?

Coz now max out my 3800+ @ 2.7Ghz using 1.5Vcore.

1.5 Vcore? Isn't it too high already?

Anyway, I manage to OC my Brisbane until 2.55GHz and I can't make it to 2.6GHz. Do I need to change PSU or better cpu cooler to reach 2.8~3.0GHz, hopefully

Toledo at 1.6v??!!??    Could you please give me some references and hyperlinks on this? If these voltages are considered safe for toledo (relatively speaking of course), me wanna OC some more!!! 

actually 1.6 is not so ok... coz i 2.70GHz @ 1.5Vcore, speedfan showing 60C++
its more when check with core temp...

so i downclock a bit running at 2.67GHz @ 1.42Vcore.. Temp is acceptable on my nitrogon nt06. orthosing at around 50C++ with low fas speed...

Just wanna know if i change mobo to KN8 <-- Not Ultra
dunno can run at lower vcore or not ler???

BTW, is my psu consider good for oc? see my sig...

@ uzairi - thx for the reference! Really helpful! 

Was wondering whether you can tell me where you got it from. Wanna see what other info they have! 

I guess my toledo would be safe until 1.5v. However, at 1.45v and at 2.84 Ghz, already 60-61'c!! More than the recommended max of 60'c..... 

ya lo... toledo is the hottest x2?  

Thanks Uzairi.

got some questions here.. does single channel really effects overclocking? before i used DDR2 667 512MB x2 at dual channel, n i can get till 2.5.. but when i add one more 512mb, it becomes single channel, and i just can go stable at 2.3. got any suggestions?
[attachmentid=252974]
This is before.. at 2.5

[attachmentid=252972]
here's at my current speed.. i tried the ram divider at 533 but still the same thing happens..

spec like in my sig..
