I've got water hooked up for my CPU block right now, SiSoft Sandra says my thermal resistance is too high. my systems seems cool enough in regards with temp indicated at around 33c, the board reports about 50c in the bios. what temp should i believe?

bios, always the bios:-)

hrrm i've heard the opposite, any how i should clarify the temp im refering to is a on CPU temp sensor, is there any more information anyone can provide? m

what cpu have you got? Are these idle or loaded temps? 33'C seems cool 50'C seems warm(if idle), either way, none of them seem problematic or dangerous. As I said before, I would definately go with the bios reading.

50c is load gets to about 55 tops when doing heavy gaming, this is clocked with FSB at 230 mhz FSB, the CPU is a athlon64 3000+

I would say that those are fine, good even for an o/c'd system.

thanks for the info. i do have 1 more question if you know. Sisoft Sandra keeps telling me thermal resistance is too high. But sandra doesn't always give the most accurate information.

"50c is load gets to about 55 tops when doing heavy gaming, this is clocked with FSB at 230 mhz FSB, the CPU is a athlon64 3000+"

55C load can be done with air cooling as well... Check out the zalman CNPS9500 or the thermaltake CL-P0024 series. As for my setup with the CL-P0024, if I switch both the intake and exhaust fan on the heatsink to 4500RPM mode, I get 54C full load instead of 65C full load at 2000RPM slient mode... I also used arctic silver 5 on the CPU...

yea but i already purchased a Titan nikita water cooling set up... i'm just trying to see to get the most out of it

I think sandra is telling you that your cooling too much, but, If, as I think, your sandra temp reading is incorrect, then there is nothing to worry about. Anyways, as far as I know, 33'C isn't too cold. I've had mine as low as 29'C.

yea mine sits at about 29C (according to the sensor not the bios) and loads up around 35C under heavy usage.

I think sandra was telling me the thermal resistance was too high as if the CPU block wasn't obsorbing enough heat

I'm seeing in a lot of post Jam is saying to drop your mem speed to 166 is this to decrease clock speed for the sake of latency i'm guesing?

depends, what ram are you using?

PC3200, well actually i'll sit it at 5\4 FSB ration since i'm going to try and take my FSB to 250mhz

"I'm seeing in a lot of post Jam is saying to drop your mem speed to 166 is this to decrease clock speed for the sake of latency i'm guesing?"

It all depends on the motherboard & it's BIOS. Some have an actual CPU:DRAM ratio setting...if your's does, you simply set it to 5:4, raise the CPU Freq to 250MHz & the RAM will run at 200MHz. Other boards don't have the ratio...but set the RAM speed to 166MHz & increase the CPU Freq to 250MHz, the RAM speed will increase to 208MHz. PC3200 will easily handle running at 208MHz.

You can confirm the RAM speed by running CPUZ.

thanks for all the great info guys... i lot of it i knew and understood but never really had any confirmation on it. apreciate all the help, i read some articles that jam posted as well.
