Is thier ever ganna be a LDT voltage Option or maybe a Vmod for the 8KDA3+ AND 3J

[CandymanCan]

Alot of people are stuck @ 2500mhz because the 2xLDT doesnt work correctly. Thier is no LDT voltage adjustment in the bios so alot of people including me are stuck @ 2500mhz.

Epoxtech do you know if thier is ganna be a bios to fix the 2x and 1x LDT ? Im ean they have the option in the bios but it doesnt work @ all. Or maybe if thier ganna add a LDT voltage option ??


Or maybe someone who knows alot about these boards can come up with some Vmod for the LDT voltage.

I'm sure there is an LDT voltage option - I'm sure it goes to 1.4v by VRef pull up.

Who would seriously need anything other than 4x or 3x at a push?

I will state a little friendly advice and ask if you could research or stop and think a little before posting all the time as you are perhaps coming across in completely the wrong way and you may not intend it.

ET, the question is not why would you want to use 2x and 1x, it is why do they not work? Candyman thinks that there is a possibility that LDT voltage is holding him back, and keeping him around 2.5. Other people using procs that had run as high as 2.8 stable are unable to get above 2.5 on this board for some reason, and feel that ldt volts are lacking.

Candyman is able to do 2.509 @ something like 1.6v and is having trouble getting anything higher stable (can boot above 3ghz, but nothing stable past ~ 2.509)with voltage as high as 1.85v (correct me if I am wrong Cman). That sounds like the mobo to me especially when others are stuck at the same exact speed when their proc ran almost 300 mhz faster on another mobo.

Cman has been doing as much research as possible. He is posting in 3 forums about this board that I know of, and is unable to figure out what is holding him at 2.509, and several people seem to be limited by this mobo at the exact same speed.

What might help candy, get in touch with someone who has gotten past the 2.5 wall with this board, and have them go through all the settings in the bios with you. Maybe there is 1 setting that is affecting your oc and you don't even realize it.

I dont now what LDT voltage is. but im hit the wall at 2680mhz(268x10).
At 2684 mhz(244x11)and(224x12) the system won´t boot.I have tried up to 1.95vcore.
my cpu is a amd64 3400 Newcastle (200x12)

Sorry for my English

[gouda]

That is a pretty good oc. Could just be the cpu topped out. What is the minimum volts required to keep it stable, and what cooling/temps are you using?

[Finetobe]

vcore is 1.680v idle and 1.760v load.
temp are 33C/91F idle and 47C/116F load.
water cooling on cpu/gpu and chipset.
if i lower the vcore the system crash when idle.
it is only 280 mhz oc. lol
my old xp-m 2500. 1866mhz to 2800mhz that oc.

[gouda]

You deffinately can not compare an oc between an xp-m and an a64...that just makes no sense. At 47c temps might come into play, but I doubt it. I have heard some say that past 1.75-1.8v they don't see a gain in stability when raising voltage.

2650 isn't bad. Your proc might just be maxed out.

I assume you are referring here to the XP-M? If so, my experience has been that some chips like volts and some don't. I've had several chips that topped out at 1.8 or 1.9v, and anything past that was just waste heat, and might even REDUCE stability. Then I've had other chips (like the one in my siggy) that just LOVE volts, as long as you can keep them cool.

[gouda]

I was not reffering to xp-m's, but a64's. xp-m's generally like volts up to 2.1v atleast as long as you keep them cool.

In that last post I was saying you can't be disappointed in an a64's oc because it can't oc 1ghz on air like a 2400-m.

[Finetobe]

yes the XP-M is a great oc chip.
Gouda you maybe right the cpu is maxed out at 2650 mhz.
so my next wish is Epox make a bios with 9.5 multiplier. I only need 9.5 .
278x9.5 that will be great.

I personally run 2.61GHz 24/7 100% stable - there is no barrier - can post at 2.85GHz, but be real on dissipated wattage!!! I could cook steaks on that at that speed.

[gouda]

It is pretty weird that with good temps he is stable at 2.5 with 1.6v, but nothing higher with any more volts even thought the temps are fine. It is possible that is just the max for the proc though, and a 2.5ghz a64 is nothing to cry about...infact I would most deffinately enjoy using that over my 1700@2.4 (my 3rd and final 4pca3+ died for absolutely no reason, so that was the end of my 2.4c@4.2 and my nf7 is under construction atm so no 2400-m @ 2.8 for a little while )

I have a feeling there is some bios option that is affecting it that hasn't been noticed. There are deffinately too many high oc's on this board for it to be a hardware thing.

[CandymanCan]

Whoa thier Epoxtech, iv been doing my fare share of research ever sincei got this stuff, iv been posting on 3 diff forums like goudo said and no one seems to have an answer.

I still find it hard to belive my newcastle is stuck @ 2500mhz with so little voltage. Epox tech i dont understand thier is no LDT voltage adjustment in the bios ? Where are getting that 1.4v from. Maybe thier is something in the bios that i overlooked? Epoxtech what are the settings in the bios that you are using ? What bios ?

[EPoX Tech]

LDT adjusts on a pull up reference so there doesn't need to be another setting.

[Beomaster]

Servus
sorry for post my question here, but I found that thread with google and belive its just the right one
I'm searching for a bios where I can raise the voltages for RAM above 3V
does anybody of you know where I can download such a bios?
Thank you

[Finetobe]

there is´t af bios for 3.0v . you need to do a volt mod on the MB. if you need any thing over 2,8 v.

[jnansley]

I'm sure Epox will be retailing the Do-It-Yourself-Volt-Mod-Kit v1.2 on 4/1/2005.
