4.0g Help (PII 940) - Overclockers Forums
A thread I started on the OC forums.. I can't get it to boot a 3.8g, no mater what I did. 3.7g for me runs fine, but it's not stable for long periods. Did you up your CPU/NB Mult and Voltage? Find the HT link sweet spot? -800mhz for me. When did you buy your CPU? I got mine early this year when it came out, I'm hoping the production dates would help work the bugs out.
What's your Vcore on the 3.5? CPUZ Screenshot? You can do the 3.5g on just the multiplier.. Check the last couple pages of the AMD OC thread.. I put some stuff in there..
1- Run the bear minimum RAM 2 or 4 gigs, and drop the freq down to 800 or 600 (Depending on your FSB)
2- What are your load temps?
3- My ram timings helped very little, I tried 4-4-4-12, 5-5-5-15 and 5-5-5-16, 15 seems to run fine.
4- lock your ram voltage at the recommended voltage on the stick
5- NB Volt @ 1.20 or 1.30
6- HT Volt @ 1.30 (1.20??, I forgot)
7- a 64b OS doesn't help clocks at all. 32b is better for OCing, less strain on the processor and less info it has to deal with.
8- Phenoms do not like heat.
Since the HT link and the NB are directly connected to the processing unit, if you just up the CPU cycles, it will basically bottleneck when information/cycles get to each of those two sections, so you have to speed those up as well..
Here's a thread that I found VERY helpful.
