X2 3800 Overclock, Advice please.

post #1 of 10
Thread Starter 
Hi all
Decided to try and overclock my X2 3800, first overclock and i simply cut the ram back to 333mhz from 400mhz and upped the FSB too 220mhz. I noticed i got quite a high HT link compared to some overclocks ive seen. What advice can you give me on going further? Is there anything i should change?

Heres the CPU Z



Thanks.

I then went further.

Set the SB to CPU HT LINK too 600mhz. Raised the FSB too 240mhz, but when i tried too boot windows i got an error message saying a System file was missing or had been corrupted.

I then reset the Bios and it booted fine. Any help reaching 2.4Ghz or Higher?

Thanks.

I would advice you to simply continue to raise the clock frequency (FSB). The HT link is not at all that great, in fact at stock speed it should be 1000MHz. As long as it doesn't go over 1200MHz you shouldn't worry about it.
Cheers!

That is true, but most members prefer to have it under 1000MHz just to be fully sure, some mobos can go over 1000 MHz, but it will far from saturate the bandwith already at 600MHz.
I'm running at a 2x divider at ~240MHz FSB and i didn't get performance downgrades.

As far as I could find on the web I don't really think you're gonna reach a 266FSB OC on that mobo, the nf 550 chipset simply can't do it. Still, 230-240 could be achievable if you lift the CPU Vcore a notch, to around 1.4V. Keep an eye out on those temps, I would keep the CPU under 50-55°C.

Ok thanks for the help, i will give the OC another try. Any ideas what the apparent corrupted file issue was?

This the kind of error you have when you have an OC that is OK for the mobo to boot, but too big for the win to boot. When I get this kind of error while OCing I lift the Vcore or Vram a notch. Don't worry, nothing is corrupted, but this is the kind of behaviour you could expect when OCing too much.

Thanks for the Advice all.

The highest Stable OC i can get is 2.25 which kinda sucks. Theres no option that will allow to change the VCore in my Bios. Guess id need a new Mobo to get some decent Overclocking results.

Seconded.
I prefer the Vcore first though. Just have an eye on the temps

Maybe you can still pun something outa the hat with this mobo too. Click here to get the latest bios from the MSI site (the 1.3), I found on a forum that with this one you can adjust the Vcore. Hope it works out, cheers!
