Squid1 Posted December 2, 2005 Posted December 2, 2005 So what kind of speedup did you see for what increase? Share this post Link to post Share on other sites More sharing options...
Budwise Posted December 2, 2005 Posted December 2, 2005 i though LDT voltage was only to be upped if you are taking the boards HTT past 2000? Share this post Link to post Share on other sites More sharing options...
Dave_Sz Posted December 2, 2005 Posted December 2, 2005 LDT or chipset voltage does nothing for me. Share this post Link to post Share on other sites More sharing options...
(cf)eclipse Posted December 2, 2005 Posted December 2, 2005 Anyone have more details on what exactly this voltage is an how it affect power to the proc? best i can tell, it's the voltage that the HT link signal operates at Share this post Link to post Share on other sites More sharing options...
Spazilton Posted December 2, 2005 Posted December 2, 2005 Raising it from 1.2 to 1.3 allowed me to lower the Vcore on my Opty 170. Down from 1.568 to 1.52. Seems to effect stability somewhat. Share this post Link to post Share on other sites More sharing options...
Kawasaki 1 Posted December 3, 2005 Posted December 3, 2005 Yeah, I raised my LDT voltage and my chipset voltage in order to get stability on my system. I really think it had more to do with the chipset voltage, but I raised the LDT to the next voltage up from default. Share this post Link to post Share on other sites More sharing options...
Squid1 Posted December 3, 2005 Posted December 3, 2005 So what clock on what CPU on what volts exactly got stable and for what test? Share this post Link to post Share on other sites More sharing options...
raphaelcvaz Posted December 3, 2005 Posted December 3, 2005 Now I finish some tests... Before incrase LDT ( 1.2 to 1.3 V ) i could get rock solid 290 x 9 w/ 1.65 V now its 9 hours runing prime w/ 294 x 9 and 1.6 V And memory in all situations is 1:1 2.5-4-4-8 1T 2.69V ( the memo can run 305 with 2.69 so it doesnt afect the tests ) But,is there some problem to my cpu to run w/ 1.3 V LDT ? Is too much voltage for ''ldt'' Share this post Link to post Share on other sites More sharing options...
Squid1 Posted December 3, 2005 Posted December 3, 2005 I'm not sure anybody know what a safe voltage to the LDT is. The only thing I know is that raising the LDT voltage from 1.2 to 1.3 V fixes the problem that CPUz sometimes fails to start with "a previous version of cpuz is running". I think this can point to a more general problem with too low LDT. I think I'll give a 1.3 V LDT a spin when I continue fiddling with my DC Opteron 175. That boy refuses to do 2.7 GHz so far (failed one core's prime95 after 20 hours). Share this post Link to post Share on other sites More sharing options...
adreno Posted December 3, 2005 Posted December 3, 2005 I guess its safe if you have not fried anything :cool: If you check the NF3 Tweeks sticky, "LDT voltage needs to be 1.75 to go over 290~300HTT" I run 9X300 with high core volts, and 1.75v LDT. Works fine for me. Share this post Link to post Share on other sites More sharing options...

Works fine for me. max LDT voltage seems to be 1.3V, while default is 1.2V. are you talking about chipset voltage instead? Share this post Link to post Share on other sites More sharing options...
