Memnoch_thedevil, very cool. I like how a 500Mhz doesn't require any Vcore increase at all. With the 3.8Ghz overclock what kind of voltages did you run? Is CPU-Z correct with the 1.376 volts?

Good luck

ya it's correct, I only added .05v to the vcore, and .1v to the NB, and put the ram at 2.0v, no other voltage increase or changes...I want to try and tighten up the memory next...not too good at that though lol

Nice clocks there man

I guess it time to start benching again with this 550...NB@3000 here we come

I think tho that The DDR3 version seems to have more Headroom with the IMC...

I agree, I think I have a golden chip here that's held back by my ram and board. I think with some nice ddr3 ram on an am3 board, especially under some water, this chip would really shine. But for now I will be happy with 3.8 w/ 2800 NB & 2500 HT with only a .05v bump to the v core

I got everything working, thanks Hondaguy! I have a few questions though. I'm pretty much a newbie when it comes to overclocking and this is my first multi core CPU. My other two PC's have single core Bartons.

My main concern is with the temps. Since I unlocked all 4 cores I notice the AOD shows -256 and I lost the per core temps. Should I be worried about that? Everest shows my Motherboard/ CPU @ 38 C's. That's with the Noctua cooler. Oh, my CPU is the X2 550 BE on a Giga UD4P. RAM is Kingston HyperX pc8500 running at 800 right now.

My other newbie question is this. What are the advantages of unlocking all 4 cores? Going off the benchmarks in Everest, I don't see any improvement. Should I leave it as a dual core for games and unlock the 4 cores for Video editing? Where will I see the biggest gains from this, I guess that's really my question.

Thanks a million guys. I tried to google for an answer but this is the only CPU I know of that can go from 2 to 4 cores...

Everest working here

Rendor: hey No Problem, thats what we are here for to help out each other....I go tthe same temps on AOD also, Just updated to the beta of everest .1771, shows the temps of the 550 as quad.
Sometimes I run mine as Dual, but when Im video editing also I will reboot into quad mode, its nice to have that option.I wouldnt worry about your CPU temp in quad mode, also change your ram to run 1066 mode, you should get better results in Everest testing...Your score will be better if you up the NB... I fond with NB@2600 with NBvolts at +200 min, will work.

RendoR, just make sure after unlocking all four cores that you run some type of stability test. This will just confirm whether or not the other cores are stable under load. Other then that good job

HondaGuy, that's interesting. I was wondering about that. So it looks like the issue is application related? I wonder why with older versions it shows 0 degree's

I think the last non-beta version worked perfectly fine with the "quad-cores" so that is kind of weird.

Good luck

RendoR · 06-30-09

Thanks for the quick responses guys, I wasn't expecting that.

I'm gonna be honest here and just say I fear the BSOD. I'm not sure how to reset the CMOS on this board. Has anyone used the Xpress recovery?

I'm using Everest Ultimate 5.02.1750. Anyone know how much the Beta version costs or where to find it? I went ahead and bumped the multiplier up to 17.5 and ran a stability test in Everest. The CPU temp reached 53 C at the highest and it idles around 41 or so. Is that about right? I ran the test for about 5 minutes w/o any problems at all. I have a Cooler Master Storm (Scout) case and a Noctua cooler. I did plug my CPU fan into the sys2 slot because the cpu_fan is really hard to get at. Will that change the fan speed? It runs @ 1400rpm now w/o any inline resistor.

I followed Hondaguys screen shots for the most part

Is there a way you can show your Ram timings? Or is that really dependent on the particular RAM you use? I have Kingston HyperX 1066mhz. It's supposed to run at 5.5.5.15 2T. It's at 5.7.7.24 on auto at 1066mhz. Voltage is 1.95.

I feel like I just asked about 500 questions guys, forgive me if it's too much at once. Mostly I just want to get the RAM timings squared away, and to make sure my temps are good.

HondaGuy · 06-30-09

Hey Rendor,,,,any chance of you filling out your sig, then we all know what you are running, I dont mind showing you my timings...you have to go into bios and manually set your timing to 5-5-5-15 in bios.... make sure that you know what your ram volts are also, as per your ram website

RendoR · 06-30-09

No problem Hondaguy... I totally forgot to fill out my sig. Thanks for reminding me

I didn't even think to check Kingstons website. I was going off Tiger Directs specs. This is what they are saying "Each module pair has been tested to run at DDR2- 1066MHz at a latency timing of 5-5-5-15 at +1.85V to +2.0V."

Everest is showing 1.95V but I never touched it (honest). Isn't that a bit high? I remember seeing 1.8 on the DIMMS.

I will check Kingstons site. What am I looking for exactly? Max voltage?

UPDATE* I went ahead and changed the timings to 5.5.5.15 2T in the bios. I can't believe I didn't get a BSOD. My old system had an Athlon XP Barton, ECS n2u400 mobo and Patriot DDR400 ram. There's no way I could tweak settings like this and get away with it. I'm truly blown away by this experience. I'm so glad I didn't go with a store bought PC.

Oh.. Is 1.95V OK? Should I run another stability test and how long? Thanks Guys!

Here's what the benchmarks look like with the new timings. Does that look reasonable?
