The weirdest thing happened today

I had my Phenom II 980 rig running for a few months and it was a lousy overclocker from the get go. Could barely do 3.8GHz at 1.46V. Recently I updated the BIOS thinking that it will solve my sleep problems (the fans would keep spinning and it would BSOD trying to wake up). I lost my overclocking settings in the process and had to redo everything from memory. I found out that the sleep problems were caused by my overclocking using FSB so I went multiplier-only now. I thought why not try to crank things up just for shits and giggles? And lo and behold - I'm now LinX testing at 4GHz and 1.452V for a couple of hours. I have a feeling that all the tests will complete successfully. I have no idea what happened, but it looks like my CPU "got better". Me happy.

Congratulations.

This is why they keep telling kids to try new things.

You never know until buy some ridiculously expensive coffee in line at starbux,

meet a hooker,

but then she turns out to be the love of your life,

and you are happily married, ever after,

and then she turns out to inherit millions of dollars,

and because you were the only one who didn't look down upon her during a difficult spot in her life,

she willingly shares the loot with ya,

and you live MORE happily ever after. :awe:


THIS IS NOT TO SAY THAT I'M CALLING YOUR PHENOM A WHORE..

But then again, computers are slutty IMHO.

wow
 
I'm not fond of hookers but have a soft spot for strippers and often contribute to their college tuition.

This is was going in my sig, but it's too long. 🙁

Wasn't it also Don Karnage that saw a huge improvement in overclockability after upgrading to the latest BIOS on his board?
 
My guess is you were hitting the limits of your memory by over clocking the bus instead of upping the multiplier.

I don't think so. Unless there's something I don't know about bus overclocking and AMD memory controllers, I set a memory divider to make the memory run at rated 1600MHz. And when I first built that rig I couldn't get 4GHz even with just the multiplier. Hope the next BIOS update will let me get to 4.2GHz 😎.

Maybe you learned how to overclock better.
 
When using just your HT/FSB speed you probably pushed the memory too far, or pushed the northbridge too far at the votage it was at. The cores were capable of more than 3.8, your instability was elsewhere, that's why using just the multi is working better. But, the best overclocks are a combination of both, you start to get diminishing returns with just the multi. As the cores increase in speed they need the L3 and link to the memory to feed the data faster. So if you overclock with just the mulitplier you are leaving a good deal of performance on the table.

But the good news is you know how far you can push your FSB/HT link, and now you know your cores can do 4.0GHz. Push your NB/L3 speed up and then use the multiplier to get back to 4GHz, that'll give you the best performance.

I had my bus speed at 240MHz so that I could run my memory at 1600MHz. I forget what the HT link speed was. I used the multi to increase CPU-NB speed to 2.6GHz, because I read in some guide that I absolutely need to increase that if I want my memory at 1600MHz. But the problem is that if I touch the bus speed my PC no longer sleeps - it appears like it's about to, but the fans keep spinning and if I try to wake up it either throws a BSOD at me or does nothing and I have to hold the power button to turn it off. Ever since I started using 8GB of RAM or more I almost never reboot my machines - just make them sleep when they're not in use so I'd hate to lose this feature. The only thing which I can't seem to overclock using just the multi is HT Link speed. No matter what I set in the BIOS, CPU-Z still reports it at stock 2000MHz.

if you OCd using the bus, it changed your RAM frequency. You adjusted the divider to compensate, but the divider is what determines the CAS/RAS/etc latency settings in the RAM. I wasn't able to get the bus past 230mhz until I manually set the RAM latency back to 5/5/5/18 at which point I was able to go straight to 260mhz on the bus.

If I had to guess this is what your problem has been.

see previous post, that multiplier lowering will change the RAM timings. I've had Phenom2s for 3 years that I couldn't get past 230mhz, only figured this detail out last month.

OMG FLOOOOOOR!!!! 😱😀😀😀 We went from a friendly conversation about a AMD CPU acting weird to strippers ?

Very interesting. All my RAM timings were on AUTO. I'm gonna try and get above 4GHz using the bus and correct RAM timings when I get home.

Edit: I just remembered something - when overclocking the bus my RAM was running very hot. With just the multi it's barely warm. That just confirms the theory of too aggressive timings. Then again Kingston T1 RAM is pretty awesome - taking all that beating at just 1.5V.

Edit 2: OC using bus clock is a no no after all. Same problems with sleep even though I keyed in all the RAM timing values by hand. Guess I'll stay at 4GHz.
