HT Bus over 1GHz

post #1 of 19
Thread Starter 
Hey guys, need some advice here. I'm trying to push my Opteron 170 to 2.7GHz right now. There seems to be an issue when I push an HT speed lower than 800, and it might be getting fussy a little above 800 as well. Is it okay to push somewhere in the neighborhood of 1080 safely? I've got LDT at 1.3V right now, but I'm just wondering if it's safe to do or not. I get a random restart where windows just tanks if I set the HT multi on 3 (if I go anywhere under 270 on 3x, she won't even finish verifying the DMI pool). It took like 3 hrs to do last time, so currently I'm trying my luck on 4x 270 (1080).

All you have to do is set the HTT multi to a range that is stable, your computer wont boot if your HTT is set improperly. It wont harm anything if you try both settings. Most likely it wont boot at the 1080 setting, so try both.
HTT does nothing for performance either, so dont think of overclocking it as a way to increase speed..

Well, still had the restarts at 840 and sub - in fact, it was really pissy at sub 800. Not only is it booting at 1080, it seems to be running just fine. It's already gone longer than at 840, and it seems like she might be happy here. Wasn't trying to OC the HT bus to try to get more speed - just trying to stabilize her.

exactly, it just needs to be set where YOUR system will be happy and stable. Seems it likes the higher side rather than the lower...good work.

She's been priming for over an hour now...so far so good . Looks like I just may be home free...time will tell. 2.7GHz dual core is beautiful, and silky smooth. If she makes it through prime, I'm going to fire up Battlefield 2 and see what she does.

having the HT bus over 1000 won't be BAD, as long as your system is stable. depends on the motherboard. for example, the Asus A8N32-SLI Deluxe has been tested up to 1200Mhz HTT and worked just fine.

Have you consider the LDT voltage?

yea +80MHz over on HTT isn't that big of a deal, when you get +100-120MHz range, you need to do what duke said and alter the voltages.

You can leave it set on Auto, Oskar (The guy who makes DFI BIOSes) created the BIOS that way. It will automatically select an HTT Multi...I've left it on auto and I'm rock solid.
