I thought that as well but this happens even in safe mode, and typically I clean my startup programs to a few essentials anyways (speedfan, fraps, riva-tuner, setpoint, deamon tools light)...

But it's noticeable as soon as a few lines are done for me, blend and in place FFT's, which is the test I typically use.

On a side note I'm back up to 3.8 Ghz unlocked!

Count me in!
Attempting unlock but I've not managed to accomplish this glitch free... stable but with glichty sound and graphics.
As a dual core I've reached a stable level with working sound.

I've tried to mess around with OCing my cpu. Highest I could get was 3.6ghz @ 1.35v and NB freq 2400mghz. When I tried 4.0ghz @ 1.4v the PC would reboot all the time at the windows Startup screen could never get into windows 7 64 bit at all. When i put it a 3.8ghz I could log into Windows 7 but it would randomly reboot when I clicked on something. My temp's were around 32c so dunno why I can't get it to run at 3.8-4ghz where others have.

Crysisanity, do you experience these issues if you were to run the 550BE as a tri-core? One of the cores may actually be faulty

RolandVet, what kind of stability tests did you perform? The glitchty sound and graphics could be due to an unstable overclock. The unlocked cores could also be bad. Did you try 3.6Ghz with all four cores? I'm assuming you tried running more then 1.3volts unlocked?

Stylez777, can you include some CPU-Z screen shots of your 3.8Ghz overclock? The cpu and memory tab would be helpful.

Good luck

When i get to 3.8ghz and try to open CPU-Z the pc reboots so can't even get it open to post a screen shot. I can tell you in the Bios I have the multiplier set at 19x and I've tried Vcore at 1.4v, 1.45 and 1.5v and cpu/nb at 1.25 still always reboots.

Here is something else interesting as well. Few post back I posted trouble with the 4th core running prime95 I get the "illegal sumout or rounding error on the 4th worker. I tried OCCT and 5 times it came back with in error in the first 2 minutes but always on a different core sometimes core #3 few times Core #0 or #1 which seemed weird. This is all at Vcore 1.35v cpu/nb at 1.25v 4 cores unlocked stock 3.1ghz. So I download Intelburn test, set it to maximum and let it do 50 passes and it came back perfect no errors but Prime95 and OCCT show errors. I'm confused now. I don't know which to believe since I keep hearing that the intelburn test put's much more stress on the cpu and if you can get past 20-25 passes with no errors you should be rock solid.

Impressive, didn't think your Zalman would do the job. How are your temps on it? Idle and load?

Hi Everyone! Sign me up just got my 550BE and so far unlock all cores and stable so far @3.618Mhz.

@ crysisanity i have ran prime95 and had the same results with some cores running ahead of the others with 4 or 2cores running, i have found out it is normal due to the fact of software running in the background and had it stable for 8hrs without errors.

Good luck
I'm assuming the cores aren't faulty seen as my bench speed increase with more than 100%.(Am I correct doing so?) I'm running them at stock speeds seen as I first want find the reason why my sound is glitchy before moving on.
I have not run a proper stability test long enough.
I've been increasing my cpu volts until I hit 1.525 but without succes(@3.1). Are there other voltages i could try increasing? (Currently running at stock with all on auto.)
I have run memtest86 as a quad @3.6@1.525 and my ram passed with flying colours.
I'm attempting this atm:
Quote:
4. Did you incrementally increase Vcpu-nb from 1.2 to 1.35v after trying to increase Vcore?
I really hope you can help me and thanks in advance,
Update:
After the increase of volts the sound changed from static to more like a error sound (bliep-bliep). This is an improvement seen as you can now cleary define the difference in note pitch!
Update2:
After leaving the vcore at default and then slowly increasing the vnb the sound got better and better. At +.050 to +.100 the sound was clear with short static annoyances in between. At +.125 the sound changed again into a sort of fast forward version which, in my opinion was not an improvement. Again am i correct in assuming so?

Nobody has a C3 X2 550?!

I have 3 AMD systems. PII X3 720, X2 550, and a Sempron 140. I've found C3 Semprons and X2 550's at Micro Center...

I suspect that the C3's should be unlocking more often, due to the high demand.
