Vcore increase causing boot problems?

[EnJoY]

I originally posted this at hardforums, so excuse the copy/paste action, I'm just lazy.


I have a Leadtek K7NCR18D PROII DELUXE LIMITED with a pretty recent bios (8/11). I've checked to see about any new fixes in the new bios, and my problem isn't one of them.

Basically I have a Prometeia on my 1700+ JIUHB 0310UMPW. I can get to 2.6Ghz at 1.7 volts totally stable. I know I could easily get higher if I could only raise my vcore. My board goes up to 2.0 on the vcore, but for some reason, when I set it any higher than 1.7(yes, even 1.725) it won't boot and I have to clear cmos to get it to start again. Can someone tell me what my problem is and how to fix it?

hmmm, i think i know your problem, get better cooling

*wonders if this is a joke* :stick:

probably bad mosfets and capacitors used, mod the rails to compensate the lower voltages the cheap mosfets and capacitors put out.

my actualy volts are dead on with what I set them too, so I doubt it's a cheap component on the motherboard. I guess it could be the PSU being bogged down, I do have a lot of fans and such. And it could be the processor....and it could be a somewhat faulty mobo I guess.... So I still don't know what to think.

i have the exact problem on an 8rda+ rev1.1

if my vcore is 1.825 i cant restart the comp, i must shut down then wait 5-10seconds then start it again.

if its 1.85 it wont even boot. i just get the FF message ont eh little display right from start

Most DLT3C's wont take over 1.775v without giving you problems like no warm-boots, setting off the siren on the nf7, etc.

guys, there was a thread about this already and they found a solution. a couple of 8rda+ rev1.1 boards wouldnt boot or randomly reset , not sure, when a high vcore was selected. i think a new batter or cooling some chips fixed the problem.

Since when?

I must be lucky then, I've managed to POST my PC with 2.3v going through my DLT3C JIUHB 1700+ :D

Thats because the voltage regulation has changed on the rev2.

I was unable to find a good fix. (tried about 5 ways)

Yeah, I threw 2v through mine while benching, which was why I asked. :D

A new BATTER!?!?! I guess they had some bad loafs, or the mobo's didn't have enough yeast...LOL! ;) :D

Just kiddin with ya saaya...I'm sure you mean new batteries.

[EnJoY]

Soooo....I guess no one has an answer to this problem? :/

[Fewture]

A have a new board now and I can't run 2V+. On my old board I could run any Vcore..even 2.3V. Someone once told me disabling APCI did the trick.. I never tried it btw..

[EnJoY]

Why don't you try disabling it then and let me know how it comes out? ;)

*bump* help please! :(
