Cpu Vcore cant pass 1.6volts

[Bacchuas[Ak-49]]

I have a chaintech 7njs mobo and a mobile 2600 xp and a 420 watt power supply with liquid cooling all around. The problem i am having is that when i increase the voltage regulator to 1.9 i reboot and check the pc health status and it says that the cpu vcore 1.6.

[Bacchuas[Ak-49]]

What can be making this problem???

[Datsin]

bit unusal the reading maybe inaccurate.. if you put the vcore to 1.6v in BIOS does the temp drop or remain the same?

[Bacchuas[Ak-49]]

I have a liquid cooling system, temp changes dont occur fast enough to tell..... when i lower the voltage to below 1.6 the Vcore readings match that, its only when i go over 1.6 do the numbers change

do you think that a bigger power supply would help out?

[Bacchuas[Ak-49]]

by the way ow did you mod the 9600 vpu to 675?

[Datsin]

nice n easy mod..

check it out works like a charm.. i only went from 1.31v to 1.5 no new hsf.

what does MBM report? or even sandra?
my nf7-s reports 1/2 to 3/4 volts lower than i set it to in windows (mbm or pcdoctor)

i like to depend on temps rather than voltage, fortunately MBM5 reports pretty accurately my temps as compared to bios readings.

if you have a multimeter and some big cahunas, i could find out what pins to check on the back of the board at the CPU to check for real voltages, if not then IMHO trust your temps, i too have a 2600-m btw.

Datsin, what bios are you using?;) cuz i'm rock solid at 11x230 @1.825v

I replaced my mobo with my bro's mobo and i was able to overclock till my heart pretect stepped in. Damn that other. I still cant pass the 210 FSB mark stabily, i think it might have to do with memory timings. I can start up windwos but it cant run any 3d intense application without shutting down. Im currently running at 1.85 volts to the vcore, i have liquid cooling so there is no temp problems yet. Have any new ideas on how to get my fsb up higher?

btw i switched it with the chaintech 7njs ultra and heart should be heat

[WesM63]

heh.. I'm kinda lost. What board are you using now? Is it the same board that won't pas 210FSB? What ram? What timings?

There is a limit for everything, water cooled or not. Give me some detailed info and i'm sure we can help.

[Bacchuas[Ak-49]]

i have a chaintech 7njs ultra, with 512mb 2x256 corsair xms 3200 CL2 optimal 9,4,4,3 timings 11,2,2,2 thru 13,3,3,3 always give some kind of problem running at 2.6 volts , radeon 9800 xt oc'ed to 480/780 with 1.6 volts and oh lets see, athlon xp m 2600 with 1.85 vcore, all around liquid cooling on CPU VPU and Northbridge. 420 watt psu. Hope this will help......

[WesM63]

Unless that ram is using BH-5 chips, I doubt it will go much higher. The xms C2 I had only did 200mhz 2-2-2-11 on my NF7-S no matter how many volts I gave them. They only mustered 225mhz 2-2-2-11 in my Athlon 64 rig.

Try rasing your Vdimm and Northbridge Voltage and see if it will go any higher.

i got lucky, my xms is bh-5 so 5,2,2,2 and 11x240@1.9v seems mostly stable. if i gave it 2.0v i am almost sure it will prime.
also i scored 7064 combined in bandwidth now!! 3642/3422:)

[Bacchuas[Ak-49]]

Yeah i figured it was my ram, i could never get the timmings right, thanks for the help, christmas is comming up soon so i might just get a new pair of ramsticks......
Hey synthohol what kind of cooling do you use?

[Synthohol]

asetek waterchill antarctica on that one:)

the review may be back up soon. (it needed help)

click my "system specs" link for details

you should see if there is a tic-tac bios for your board, the mantaray xt cpc off did wonders for stability over 220fsb
