Just been trying my hand at OCing... A64 3200+ NC / Asus K8ne-dlx
Problem is that I cant go beyond 230MHz because of my SATA drives (on SATA1 and 2)
If I disconnect both of them and just run XP on my IDE Maxtor I could reach 260MHz easily (but got bored of running Prime and stopped it after 11mins. wanted to play NFS:MW) with RAM at 5:6 divider (and 2.5-3-3-6 1T i think. dont remember exactly) and CPU mult at 10, HT mult at 3.

Currently I've disabled Silicon Images RAID option in BIOS but I have the option
to enable it and set it to SATA mode rather than RAID. I can then
connect both my SATA drives to SATA 3/4 (which have locks I believe) and then
try and OC to the limit.

Question is whether I'll corrupt the drives' data. I dont want to risk that...
 
umm.. well they are connected to the ports just below the CPU. Those are SATA 1 and 2 (and the drives show as 3rd and 4th IDE Master drives after POST) the SI ones are at the very bottom of the board (near the LED connectors) and these are SATA 1/2 3/4.

found this just now :(
Code: 
The decision by Asus to use Silicon Image SATA instead is really a drawback in overclocking. Whether using the 2 nVidia SATA channels or any of the 4 Sil3114 channels, the highest overclock that we could achieve with our standard SATA drive was 230, much lower than some other nF3-250 boards. When using an IDE drive, the K8N-E fared better, reaching a stable 271 FSB at 1:1 before failing boot. While this is a much better overclock, it is still below the performances of the DFI, MSI, Epox, and Chaintech 754 boards that we have tested.

Due to the overclock limits found with SATA drives on the Asus, we would recommend using IDE drives with the Asus if you plan to overclock. The Asus can handle reasonable overclocks with a SATA drive, and we confirmed AGP/PCI is definitely working. However, the highest overclocks could only be achieved using IDE hard drives.

OK.... hoping against hope I had enabled the Silicon Image in SATA mode and connected both the hitachis to SATA port 3 and 4. prime failes exactly at 231 . same like last time. So its proven... cannot OC on this board beyond 230 when using SATA drives. :(

So i'm now on stock speeds... bah. everything is favorable for a good OC and now this...
 
What bios version are you on? I reached 300 on a k8n-e deluxe with sata drives on the nf3 ports. Never used the silicon image ports cos they are pci bound and hence slow!
 
Nop....that's way to early to have SATA/2 problems. I have had problems beyond 300 with my RAID 0... I ruled out Memory by Memtesting @ 310 @ 2.5-4-4-10. Processor (X2) was cool with 9 Multi.... but booting into Windows was a no go. I am gonna try with 80GB PATA....yet.

BIOS version is 1006. currently both drives on nf3 ports and I could not go beyond 230. and that's also what's mentioned in the links I posted earlier. hmmm. what BIOS version are you on? CPU voltage was 1.525, RAM 2.5 (Auto)
 
alright. digging up an old topic as it is related.

I took out one stick of 512MB ram out of two, kept the other one in slot 3 and started to OC. reached HTT upto 306MHz after which it rebooted. so i guess 300 is a safe limit.

when I started the CPU OC to check its limits, it is not going beyond 217MHz x 11. Prime fails after about 20mins. even tried to raise the voltage to 1.6v. I guess the stock is 1.550v.

ram at 1:2 divider @2.5-3-3-6-1T and HT at 3 for both tests (CPU and HTT)

CnQ disabled, both sata drives on nvidia ports and not SI ports.

AGP/PCI locked by setting it to 67MHz.

so whats the issue here.
 
^^Stock is 1.5. Since you have an SI-120, you can safely up the voltage upto 1.7V without too much of a worry. Check how much your CPU does with that voltage. Probably you have a dud cpu.
 
well tried that. actually only upto 1.675V. wouldn't go beyond 217x11=2387.

then tried at 10 multiplier and could reach upto 247 this morning.

prime failed after 53minutes. will try 1.7 tonight. temps around 53-56 with case closed.

btw: anybody OCed 6800GT? i could reach upto 403/1100. good enough? the fan's going bonkers.

1.5V AGP.

I could reach 425/1050 but 425 is too hot and temps soared...Since I am lazy to downclock for regular use I set it @ 375/1020 a modest OC...
But make no mistake (Nikhil had something nice to say about my 6800GT :P ) it does a 425 MHz played farcry for an hour no probs... mem haven't OC'ed beyond 1050 MHz though....;)
 
@SpitefulPentium - Running @421/1150 all the time on my 6800GT with a NV5 Silencer. Load temps do not go above 70/71. Max I was able to reach was 431 on the core.
 
alrighty...

how's the noise of the nv silencer at that speed.

cos the stock fan is causing a racket.

plus the amd hsf mod is not helping either.
