Help me hit 4GHz+(550 BE)

post #1 of 7
Thread Starter 
i have tried many time but i can only boot 4.0ghz and it crash after 2 min of just sitting at my desktop... im @ 3.99Ghz its still unstable but i was checking temps(which are fine 24C) ive dumped 1.65V into it and it STILL wasnt stable( lasted 2 minutes more) i have my memory as slow as wit will go(800Mhz)my NB is @2100(doesnt like to overclock)
Any sudgestions?

go down to one stick of ram,ideally your stick that can handle the lowest latencies.
1.65v is very high for air cooling!
i wouldnt use that even with chilled/phase.did you try 20x200?so the fsb isnt stressed,only the cpu.

HOLY SMOKES SIR, IF YOU DON'T DOWN YOUR CPU CLOCK OR LOCK THOSE TWO CORES AGAIN YOUR BOARD IS GOING TO BLOW!
Seriously!
You are pushing way too much voltage on an overclocked 125W processor (x2 unlocked counts as 125W) on an unheatsinked 3+1 power phase running a tower cooler which means the VRMs are being pushed way past their limit and are getting no cooling whatsoever and the combination of all these factors herein puts your system in large, LARGE danger of FLAME DEATH!

You need to realize that what you're trying to do here is extremely dangerous. First of all no 3+1 power phase should EVER, EVER be running more than 95W and that's without overclocking. Many higher-end motherboard manufacturers only rate their 3+1 phases for 95W - and ratings are always done with the stock cooler & no overclocking. Second of all, you ARE overclocking and using something other than the stock cooler (which doesn't blow onto the board/VRM area). Third of all, boards can and will blow - don't make me bring out all horror stories!

I'm actually surprised you're still alive. With 1.65V into a 125W processor on a worse than inadequate power supply, your board should've blown within 10 minutes of stress testing.

The last thing I'd like to say is that overclocking the CPU is not really worth it past a certain point anymore unless you overclock the NB with it. Higher NB allows an overclocked CPU to more memory access which is significantly faster. I'm not sure why the CPU-NB won't overclock on that board... perhaps it's that single split power phase that's for the NB (the "1" in 3+1) being just a tad bit weak.

I only did the 1.65V for 20 min while fussing around with settings and yes ii have tried 20x200 did the same thing...

A. sorry for double post... B. my HS is oddly made(i think atleast) it has a space between the heatsink and the fan itself and air comes out the bottom(toward the board) it cools my NB alittle but my MOSFETS are VERRRRYYYY hot(i thought it was normal) so i usually have my case opened with a 140mm or 160mm desk fan blowing into it. AS for my NB i can only hit 2600 with 2 factors(1. 1.8V 2. Ref.clock of 220) i have tried with only 1 stick of ram and it didnt change... i honestly think my board is my bottleneck(its holding me back)Temperature has never really been a probem for me(hottest thing in my case is 40c and thats my GPU)

Here ill help ya try to get 4Ghz. Just follow these tips

1. Boot into Bios
2. See how far you ca push the frequency of your CPU before you crash...
3. If you crash at a certain frequency, then push a little Vcore at a time, not to much though. You have to try balancing Vcore with Frequency to find a sweet spot.
4. After you have found the most frequency and Vcore you can push into your CPU then, start OCing your CPU-NB... Remember just balance voltage with frequency..
5. Same thing as in Step 4 with the Regular North Bridge..
6. Its just a process of going back and forth trying different settings. Its all about balancing, patients, and effort..

Took me a while to get 4.0Ghz on my 955, even though it wasn't stable for more than 2 hours it was a good goal for me to complete. I have a C2 so its w/e..

*NOTE* Never push above recommended voltages unless you have proper cooling...

Have fun and gl ocing ^_^

Mosfets can fail over time as well as instantly. If you say they are VERY HOT right now, that is enough of a sign. You will indeed want to lock those two cores and go back to stock until you get a better motherboard.

On my list of mosfet horror stories, there are only a few involving 3+1 boards and Phenom II because any educated person here wouldn't ever fit Phenom II with a 3+1 board:
http://hardforum.com/showpost.php?p=...&postcount=206 - MSI 785G/mosfet fail/underclocked and undervolted Athlon II x4 (95W) [3+1] - 10/6/2010
http://hardforum.com/showpost.php?p=...3&postcount=18 - 3.8Ghz 1055T/785G-E45 [3+1] - blew up within minutes of stability testing - 6/11/2010

I can post the rest if you want, which involve 4+1 power phases and various 125W chips.
