Hi Everyone,

New guy here. VERY little experience and knowledge. Just built my second computer with the 6150k8ma 8ekrs, single corsair xms 1 gig DDR 400, no video card, crappy little 250 watt power supply, and AMD athlon 64 3000+ CPU. This is my first attempt at overclocking. Here are the results. Any questions, comments, advice???

First attempt. Changed nothing but FSB. Made it to 230 with occasional weirdness. Bumped up vcore 20mv, and memory voltage 50mv. Seemed quite stable doing stress analysis with Solidworks/Cosmosworks.

I then tried the following. Put voltages back to stock. Reduced all HT multipliers to 3X, and brought mem speed down to 133.

Incrementally raised the FSB to 270 with no problems, the raised mem speed to 166. Haven't tried going any further.

I have been running Prime 95 for 1.5 hours now (Still running while I write this) and browsing the internet with as many as 3 explorer windows open, plus the Foxconn Super Step so that I can monitor temps, and Outlook running all at once. Temps stabilized at 30 system, and 41 CPU.

This seems quite amazing to me since I really have no idea what I am doing. In fact I only lowered the multipliers and mem speed because I read it on the internet. Did I just get lucky and stumble across a good setup?

The only thing I have noticed is that using Pass Mark for testing, my 3D graphics have slowed down. Even at the current FSB speed, the graphics are still slower that they were at 230 fsb with all other settings stock. They did get noticeably faster when I raised the mem speed to 166.

Any ideas? Is there more to be gained?

I hope this helps someone, and I would be interested to hear from any experts.

Hi there,

Thanks for your input.

I was mistaken about the power supply. It is "rated" at 380W. I don't have any voltage droop when starting Prime 95, and I don't plan to add a video card, so I think I will keep the existing power supply.

After having a week to do more research, and testing, I have found that the memory is keping me from going much past 270. I could change the multiplier, but then I would have to raise the FSB to approx 300 to get back to where I am now (224 DDR448?) I would rather not loosen up the timings to go higher, as that seems to make things a bit sluggish, regardless of what various test programs say.

I am looking for some memory that will run at 270 with reasonable timings so that I can change the multiplier back to 1:1. I would like a 1 gig stick. If I can find something that will run at that speed, I will probably just leave it alone after that. I don't want to raise voltages.

BTW, it has gone about 10.5 hours on Prime 95 with no errors before I shut it down manually. Any suggestions?

Thanks again.
