FallenCow Posted March 6, 2006 Posted March 6, 2006 The board will not POST/Boot at all when I try to change the VCORE from AUTO to anything else. I will then have to reset the cmos in order to boot again. This is very disappointing as I'm trying to overclock my opteron and it will only go to 2.8ghz w/o being able to change the cpu voltage. Would I be able to solve this problem w/ a new bios or is it my board? I'm running the 12/07 bios that came preloaded. Thanks for any help!

FallenCow Posted March 6, 2006 Posted March 6, 2006 No one has any suggestions? Do I have a faulty motherboard? Quote Share this post Link to post Share on other sites More sharing options...
RGone Posted March 6, 2006 Posted March 6, 2006 Set LTD/FSB to X3.0 Set CPU/FSB Freq to X9.0 Set CPU VID STARTUP to 1.425v Set CPU VID CONTROL to 1.350v Set CPU VID Special Control to 112% And there you have your instant ~ 1.49 volts if I remember correctly.

FallenCow Posted March 6, 2006 Posted March 6, 2006 I'll try that setup, but I'm afraid that it still doesn't solve my initial problem. What good is a motherboard when you can't change the cpu voltage?! Report back in a min. Quote Share this post Link to post Share on other sites More sharing options...
RGone Posted March 6, 2006 Posted March 6, 2006 And there you have your instant ~ 1.49 volts if I remember correctly. I would think 1.49volts would be a voltage change? No? Yes? Humh? You can substitute other values for volts for sure but the process of setting all the other to a 'known' solid value and NOT 'auto' is a must. RGone...

FallenCow Posted March 6, 2006 Posted March 6, 2006 Well I think I figured out the root of my problems. It seems the board will not boot unless I manually set a cpu multiplier. I tried your suggestion RGENE and it worked perfectly, so I was curious as to why and once I took the multiplier off AUTO it POSTED. Now what I have to figure out is why it keeps rebooting w/o even trying to load windows when I try for an FSB above 280. I was able to boot into windows with an FSB at 300 and the cpu at 3 ghz w/ my old Ultra-D board. That board was a dream to work w/ compared w/ this one! Also, what does the LDT/FSB ratio affect?

FallenCow Posted March 6, 2006 Posted March 6, 2006 I finally got it to boot 3ghz, but only with the cpu/fsb frequency ratio set at 9. This is basically the multiplier correct? I thought opteron 146s were multiplier locked at 10? Is there any disadvantage to having a cpu/fsb ratio lower than 10? Quote Share this post Link to post Share on other sites More sharing options...
MnemoniC Posted March 6, 2006 Posted March 6, 2006 it happened to me once when i just bought all new things and assembled it... i can't changed my opty vcore also on the expert.. but after a week using n a few times run sp2004.. i can change the vcore all the way i want...

FallenCow Posted March 6, 2006 Posted March 6, 2006 I'll try burning in this board for a few days before I try to overclock my processor again. The quirks on this board are still very perplexing. Quote Share this post Link to post Share on other sites More sharing options...
