Phenom II Overclocking Guide - Page 7

post #61 of 253
Thread Starter 
I think you've made a good choice there, and its mostly because the ram doesn't play a huge part in the performance of the system (high speed vs low speed). Usually the difference is somewhere around 2-5%. Its kind of strange that your OC got LOWER when you used less sticks of ram, which might indicate that there is something going wrong. However an OC of 3.8GHz with the NB OC'd to 2.2GHz and 8 gigs of ram is pretty good. I'd probably stick with that if its stable, since its not to likely that you'd notice the faster ram, and especially not if you have to give up some processor OC to get it.

Also, like I mentioned in the guide the NB can make a big difference when it is OC'd, and that is one of the things that you can miss out on when you OC with the multiplier alone. Usually the best performance comes from high NB OC's and tight timings on the ram.

Good luck man, and yes, thlnk3r is amazing. Its people like him that make OCN a great place

Thinker is a a great man and you are not to shabby yourself sir! .

i cant seem to get 3.9 stable for more then an hour. the NB bridge voltage doesnt seem to make a difference at all. I havent touched the chipset voltages would that increase stability by any chance?

Younggrasshoppa, I noticed in your last screen shot that your HT Link speed was at 2230Mhz? Try keeping that at 2000Mhz (stock) if you can. If this speed increases it can cause stability issues and possibly also prohibit you from overclocking your cpu.

Just to clarify it looks like you are running two different types of memory? I'm not sure if that is a wise thing to do only because you may run into timing issues and possibly even more if you decide to increase the memory frequency. Just a thought...

Good luck buddy

for some reason when i manually set the HT to 2ghz its still reads at 223 or whatever i have the fsb and NB speeds set to when i boot.

Im aware of my ram but ive decided losing 4 gigs isnt worth the performance loss in boot and loading of random window just to get another 100 or so mhz out of it. i can get 8 gigs at 880 stable, without touching any of the ram settings whatsoever. I realized early that the whole ram OCing is over my head for now at least

When i run with 4 gigs at 1066 i cant seem to get nearly as good an OC, overall
(i know that strange but it seems to be the case my mobo is very touchy with ram speeds from what ive noticed). My board caps more then 4 gigs at 800mhz ive managed to get it to 880 only by increasing NB speed.

Younggrasshoppa, you should have these options available: [200Mhz], [400Mhz], [600Mhz], [800Mhz], [1Ghz], [2Ghz], [Auto]. After making the changes hit the F10 key. That should save the changes that you made.

Let us know

Good luck

Good luck
correct i do have those options. But the moment i change my fsb/nb speeds it seems to take the same speed as my HT/CPU frequency which i will explain

to get my NB/FSB speeds to increase i have to increase my HT/CPU Frequency (<---exactly how its shown in my bios). I dont have the option in my bios to single out the FSB,NB speeds Those two options seem to be controled by the HT/CPU frequency option. It gets all lumped together into one option which i can change from 200-550. i hope that makes sense

I really think its my mobo and a crappy bios that are holding me back. but if 3.88 with ram @884 is where i get to im happy i didnt even know what overclocking was when i bought my machine

Wow... great guide. If I ever get that PhII rig I've been itching to build, I definitely have a reference point to start overclocking. Excellent work.
