3700+ Oc

[master811]

I'm trying to OC my A64 3700+ a bit more. Its currently at 2.6GHz (from 2.4 GHz stock). Pushing it much further makes it unstable in games and gives superPI errors. I've already boosted the vcore by 0.2V (I can't go any more in my BIOS). Though I can get to windows with a 222 Mhz FSB, generally its not really stable at load at anything above 218 Mhz ish.

I can't seem to change memory timings in my bios (though wouldn't really know what to do as never really OCed before this), and I have been told that I might need to go back to a previous version which still had those. Can I assume that its my RAM thats holding me back and making the system instable?

Any ideas.

Most likely. I got a 3000+ to do 2.8ghz on stock air. I had to use a hefty mem divider to get that.

I notice your using a Via chip based asus board too. While excelent stock chips theyre not really designed with overclocking in mind.

Your right however, it does sound like your memorys limit. Is there no memory settings at all in the bios? Theres usualy a memory frequency/clock setting even if you can't control the timmings.

Aye, based on your sig, I'm pretty sure we have the same RAM. Mine are hard-pressed to do anything above 220mhz

HAM is right , your motherboard is the major bottleneck here. One thing you could do is try running your ram on a divider and then lowering your multiplier and raising your HTT speed , also you "might" have infenion chips , which respond nicely to 3-3-2-6 timings , and might go higher , but they dont like high voltage , try to keep it around 2.5 ~ 2.7 V . Raising your fsb speed will give you a decent boost.

Thanks all for your input.

I managed to figure out how reduce memory speed with a divider. Lowered it to 5:3 rather than 1:1 that it was before, although am pretty new to this. Obviously lowering would allow faster FSBs but are there any big performance/problems drops from lowering memory speed too much, and any problems for increasing FSB (as long as I keep CPU cool) before I try to push it more.

Thanks

*Well anyway, I got it upto 221FSB without any problems, not tried anything more just yet.
