NF7-s Wont go above 1.85v

[athlon3400]

Everytime I try to up the voltage past 1.85V the system wont post, but the board is rated for 2.3V!

Specs:
Abit NF7-S Rev.2
AthlonXP 2500+ @ 200*11
Radeon 9600 430/250
512 Kingston Hyper-X 3200
WD 200 gig SATA 7200rpm
Sony 52X cd-rw
dvd-rom
ThermalTake Aquarius II
Antec True Blue 350 Power Supply


Thanks For your time!

It might not be your mobo but Power Supply or your CPU can't handle that high voltage!

Good or Bad have no meaning at all, depends on what your point of view is.

You really shouldn't be trying to push your voltage past 1.8, anyways.

My cpu is liquid cooled and my temps are around 45-47 at 1.85 so im not to worried. its not that I want to keep it above, i just want my mobo to do what its supposed to do.

Seems like your mobo is doing what it's supposed to do. It's telling you there's a problem going over 1.85v.
The bad thing about water cooling is that there is no fan on the chip. That fan helps to keep other parts of the board cool. Try taking the side off the case, and aiming a housefan to blow in. If this works, it means that you need better irrigation.

Could it posibly be the mosfets? They are hot to the touch, but i always thought they were supposed to be that hot.

 

[ChipDeath]

They are hot, and get hotter when increased demands are placed on them (such as you're doing)... Plus they are right next to the CPU socket so they're probably now missing out on a little airflow that they would've had with a standard HSF.

Buy some RAMSinks and stick those on - or there are waterblocks available for them - and see if you can improve your case airflow a little perhaps?

I put some ram sinks on the mosfets, added another case fan, removed the side panel and set up a house fan blowing directly into the case. Case temps are now at 19 degree's celcius and at 200*11 my cpu is about 42-43 regular use.


Does anyone have anything else that could be the culprit? May it be just my cpu? or could it be a weak power supply?

my voltages are as follows-
+3.3 - +3.25
+5.00 - +5.00
+12.00 - 11.92
-12.00 - 12.85
-5.00 - 5.04

Voltages look ok..... Maybe it <i>is</i> just the CPU disliking the voltage.

Although an XP that won't go above 2.2Ghz @ 1.85V is probably not going further anyway . I've heard that a lot of the more recent 2500+ desktop chips aren't very good overclockers anymore... I guess they're all being turned into Mobile XP chips.

I would buy an XP-M in your position and see what happens.
