can ultra-d take these volts??

[LemonyLime]

Is it safe to set LDT and chipset voltage to their maximum? I don't want to break the board, but I see some people doing it. I just want to know if the board is really designed to handle the volts...I'll worry about the heat.

 

Thanx

A related question - does maxing these voltages actually help get a higher overclocking speed?

There was a benchmark (I forgot was it Neoseeker?) It showed LDT beeing dropped from 1000 to 800 to 600 to 400 to 200, and the performance is negligible. It's not even like PCIe 16x all the way down to 1x. I remember the performance of LDT dropping was exactly the same (maybe 1 or 2 3dmarks difference).

 

I recommend you keep it below 1000. There's no reason it needs to be high. IF you're using anything above 210 just drop it to 3x.

to Dexx...I don't know if it will help yet cuz i'm afraid to max them out but...I have tried everything and I mean everything to get my winchester to OC higher than 2.3ghz stable.

 

To dmo580...I've done the lower LDT at 3X and every possible combination of things except raising the LDT and chipset voltage to max. hehe...this will be my last shot.

 

I've actually learned alot about OCing an A64 here and I've had a blast so far even tho my results are kinda weak. I believe I have one of those winchesters that has a weak mem controller. Every test that has been recommended on this site i've done and it leads back to the CPU. My memory will go DDR540 at 2.5,3,3,6. I'm struggling with the fact that my CPU is one of those duds and I can't seem to let the issue go..you know how OCing is..heh.

 

Anyway, I think it time for me to just throw in the towel on this CPU. Maybe in a few months I'll be able to afford a venice.

How high can you go on stock voltage? What voltage are you using at 2.3 GHz? What kind of cooling are you using? What are your temps? Have you tried lower CPU multipliers? (9X) Have you tried running your memory at 2T (CPC Disabled)?

I have tried every thing you've mentioned and more. I have become very familiar with all the OCing formulas posted on this site. I have even gone back to the OCing guide and started from scratch several times trying many different combinations of things. My way or the OC guide way = same results.

 

Right now I am running 256X9 4xLDT- prime 95 stable- the comp seems to like high LDT better but my ram is faster at 9x multi with 4X LDT ..so i leave it there.

I can run 230 X10 at 5X LDT but thats wasting the memory speed potential. I get slower benchmarks.

 

vcore 1.30 sp vid 123% = 1.599v - i have gone up to 1.67 volts to try to get it to run at 2340mhz but its not prime stable for hours. Likewise with LDT and chipset voltage..If I raise it, it will run prime for longer but eventually it fails.

 

temps in fahrenheit are: idle cpu-95, chipset-106

load cpu-104 , chipset 113

 

I have a YY cube server case...as you can see temps are not an issue.

 

I should have looked at the cpu to see what week it was made b4 installing it but i didn't. The chip is at its limit I guess. It kinda sucks because the memory has so much more to give.. at a 10X. oh well...better luck on the next chip.
