Question About Core Unlocking

post #1 of 7
Thread Starter 
Okey, i finally got around to getting a new MBoard, which is ASUS M4A78LT-M. It has core unlocker and all that, which shows as "Press 4 to activate Core Unlocker" at startup.

It went through unlocking just fine, and boots into linux w/o a problem with all 4 cores, but not exactly sure if thats enough to call it stable w/o any OC'ing. Is it necessary to use P95, or can i just leave it like that?

You do need to test it with Prime.

If you want to use your system for right now, I'd say wait until you go to bed and run P95 while you're sleeping(watch for a few mins to make sure nothing goes horribly wrong), then when you wake up you'll know whether it's stable or not. Either way, run P95 for sure.

Booting into an operating system is absolutely no way to gauge stability. You should run some form of stress testing for a while. It doesn't have to necessarily be prime95, I would imagine Linux has some applications similar.

Finally installed Win7 again on rig, going on 25 minutes with P95.

And as to OC'ing DDR3 rams, im a complete noob :/

What kind of voltage should i be looking at if i want either 1800-1850MHz?

And should i make use of LLC?

Aren't all Phenom II 550s C2 stepping? C2 memory controller is pretty bad, I don't know if you'll be able to run 1800mhz+ stable. Hell my C2 550 and 720s couldn't even run 1600mhz. So I would just not mess with frequency, but rather play with timings. Lowering the timings on a 1600mhz or 1333mhz divider is going to be easier to do. You can run memtest86+ to test for stability.

LLC is a great feature, which would be keeping vcore as consistent as possible. So yes I would use that.

My 550 actually has C3 Stepping from what i could see on cpu-z, so there might be some hope?

But kind of leaning towards not going above 1.8v on ram voltage.
