9850 BE Overclock Issues.

post #1 of 5
Thread Starter 
Hi,

I am new to all this overclocking thing but I am trying to get a stable overclock.
Yesterday I tried to OC my CPU to 2.875GHz by raising the HT reference clock to 230 and keeping the stock multiplier @ 12.5, I also raised the CPU Vid to 1.312.I saved it in bios and restarted my PC. It booted fine up untill It got to the part where windows was being loaded.. It froze right there.. I dont understand. Every OC I tried except the 1 where I upped my multi to 13 (2.6ghz) kept getting me either BSoD or windows couldnt even load. I tried loading in safe mode, same thing..

You've probably pushed the CPU-NB (basically the L3 cache) speed too far with that HT speed.

The MSI's are bad for that, as they virtually ignore its there.

Either that or your HTT Link speed is to high (IF you havent changed the stock HT multi your looking at 4600Mhz...Ouch).

Im not familiar with your BIOS but there are a couple of things to try:

Raise your HT freq in steps of about 5Mhz. Find the max you can get without failure to boot.

At your current 230Mhz, lower your HTT multi to either 9 (1800Mhz) or 8 (1600Mhz). Also try upping the HTT link Voltage to around 1.3v-1.4v

Also slightly overvolt your northbridge and southbridge.

Your vcore wont really matter here much. You arent running at monstrously high speeds for that chip. Ive seen plenty do 2.8 at stock voltage, so keep your vcore the same.

post me some pics of your BIOS layout and I might be able to help some more.

Yap bring your HT and NB multi a bit down. Set your RAM speed one step down in the bios. And First of all disable CoolNquiet in the bios and if there is any other spread spectrum disable them also.
