Hey there, I'm helping my friend overclock his Opteron 165 socket 939 cpu and I just have a question about HTT. After reading the old dfi-street AMD overclocking guide, it says that I should keep the HTT at around 2000. Would there be any performance loss if I have it lower? I currently have the CPU running at 290x9 which results in an HTT of 1740. It has passed OCCT and SuperPi 32M and is currently still Prime95 testing (been 10+ hours stable). It's kind of an old CPU, but I'm hoping someone with socket 939 OC experience comes across this thread. Any help would be appreciated.

I feel like a complete noob when it comes to overclocking and bios settings, so thanks for all of your help! I'm going to try to lower my ram divider or give my cpu more voltage if that doesnt work. Hopefully, one of the two will otherwise I wouldn't know what else could have caused my boot problems.

I've been using a 2.4 divider having the ram set 1:1 at 800mhz since this is what the ram is rated. Should I lower the divider?

I just received a memory dump bsod as I turned on my computer, so I had to revert back to default settings.

Thanks for all the help. I'm using a Gigabyte EP45-UD3P btw. I encountered a problem this morning when starting up my computer and it said there was a problem while shutting down and gave me the option to boot in safe mode or to start windows normally. I started windows normally and it said that windows has recovered from an unexpected shut down. I was in the decision of lowering my core voltage even more, but I'm unsure if this boot problem was from the OC or not because I've been running at 9x333mhz for 2 days. Also, the longest I've ran prime95 for so far has been for 3 hours stable. Apparently, I also misinterpreted vdroop. I have my cpu voltage in the bios set to 1.2812v and it shows up as 1.23v in cpu-z while idle, but under load it drops even lower to 1.216v. Is it safe to keep it at this?

Hi, I'm new to the forum as well as overclocking and I decided to overclock my Q6600 G0 2 days ago. I disabled the auto vcore setting it manually at 1.2812v, and cpu-z shows my vcore as 1.232v. I know this is called vdroop, but should I pay any mind to it? When other overclockers post their vcore, do they post the one showing in cpu-z or the voltage they set in the bios? Aside from that, I've heard how an audio card can free up the load on the CPU, so would that mean I would get lower temps from using an audio card instead of onboard? I'm wondering if I should throw in an audigy 2 that I've had stored away for a while.
