OC BE 965 + Gigabyte MA785GM-US2H

[Prolab]

Hey Guys/Gals,

I've had this rig now for almost 8 months and decided to dwelve into OC again. I use this rig mostly for encoding movies and now playing SC2. I also recently bought CoolIT WC system and i thought i could squeze it to 4 ghz safely.

Well, ATM im currently running 3.8 ghz using the BIOS settings (19 x 200 mhz/everything else auto). Ive tried pushing it to 4.0 ghz but it keeps restarting. When i was cleaning up the goo off the processor/AC cpu heatsink, i cleaned it up with alcohol pads and coffee filter. Applied AC MX-3 using the pea size guide. I didnt see much difference (temp wise) according to speedfan (4 cores - 100%; 68C). Is that normal?

Im going to re-apply the thermal grease and see if that makes a difference. I felt like i messed up (i struggled installing the coolIT pump, trying to catch the backplate to screw in).

Can i safely OC this rig past 4.0 ghz? If so, is there a guide i can use to see if i can push it even further.

System Specs:

AMD BE 965
Gigabyte MA785GM-US2H
4 GB Kingston DDR2 1066
MSI 4890 T2D1G


BTW, i also messed up taking the CPU/heatsink out and end up bending 5 pins . Good thing my hands were steady and a mechanical pencil was at hand. I almost crap my pants bending the pins right back .

Have U activated ACC & Unleash yet?U might want to try going for 3800MHz with a different approach like what I did(225x17),can further increase NB/HT Link & memory bandwidth & speed,but u have to manually adjust the voltage thoughWindows will make it hard to boot into @4.0GHz,try doing it with AOD,afraid hitting 4.0GHz too often may fry your mobo

thats a healthy oc...but but..remember to properly drop some airflow around the socket area because

Well, re-applied the grease and didnt really made any difference in temps. It was no better than my old AC heatsink.

Anyhow, thanks for the recommendation. I did the timing manually (225 x 17, CPU volt = 1.47, memory = auto), but it was unstable for me. I end up using my old settings (200 x 19, everything else auto).

No, im reading through this forum:

Phenom II 550 + Gigabyte MA785GM-US2H = 1066? - Overclockers Forums

Is that a good start on values and tweak it a bit for mine?

BTW, im starting look for a DDR3 memory. Ive checked the website for the compatible memory list and i didnt see G.Skill on that list.

I was reading Is any memory tested for AMD? that AMD's usually are compatible on dual channel rather than triple.

Geez, ive been out of the loop in OC for years...
