Tbird/ Duron Temp &VCORE poll

Last response: in Overclocking
March 29, 2001 4:19:09 AM

Just kind of a little poll, what VCORE (core voltage) are you overclocking Tbird owners running. Also, what kind of cooling do you have and whats your idle/ full load temps? I hope this can kind of be a "go-to" post for anyone with temperature and voltage questions. Ill post mine as soon as I get done tweaking my overclocking.

well i after applying my Artic Silver 2 (what an experience, brought my temps down about 8c!!!!) and playing around with my overclocked settings (on 800 tbird), i found the highest stable speed to be 997.5mhz (9.5 x 1005)!!!! I am just 2.5mhz from having a gig, the magic 4 digit number, DARRRRRRRRRRRRRRRRRRRRRR!!!!!

VCORE: 1.85v
Cooling: GlobalWin FOP 32-1 (lapped) w/ Artic Silver 2
Idle Temp: around 40
Load Temp: around 45

a question for you guys: how the hell do you have so low of temps? i have a damn good cooling system yet im about 10c higher than you, anyone have any ideas?

The only consistant (precise) way to measure temps is with an external probe. Every motherboard is different, and like 'Asus Probe', some do a little interpretation of the actual temperature for you so you get a more 'accurate' reading of the processor.

A comp-u-nurse works well, if you can get it close to the cpu without crushing the thermistor.

TB 850 on Asus A7V133a
Taisol HSF
1.85v Core
133x7.5 = 1000mhz
Idle: 58 or so (I'm always running SETI)
Load: 58-61c

I know that seems pretty high right? I posted in the forum a few weeks ago asking if anyone with the Asus A7V133a board was seeing such a high temp and I had a few replys from guys telling me that their temp was registering VERY high on that board. But on previous boards it was fine.

Someone suggested that the temp monitor was positioned too close to the CPU but I haven't checked yet. My temp is still well within operating spec (80c is the max I think) and the machine is stable under 98/2k so I'm not too worried. But when I see the numbers posted here I can't help but feel a little nervous. Aside from getting some Arctic Silver anyone have some suggestions? The machine runs at 56c when the voltage is 1.70 so the O/C isn't pushing it up that much.

Other factors: Appartment room temp = 74, Side of CPU case is always OFF, a bigger Fan for the HS is not possible (the machine sounds like Wind Tunnel as is and my Appartment is small). HS compound from RadioShack took the temp down about 0c. Sigh.

Enjoy your cool CPUs and worry free lives....
March 29, 2001 11:56:06 PM

well, since youre always running seti, i would say that would bump up the tmep since your cpu is always cranking away calculations, but thats just my speculation
as for my situation, all is not so well as i thought. my machine has started having memory errors (under w2k) a tell-tale sign that my overclock is unstable. right now im at 9.5x105 on an tbird 800 w/ A7V so im thinkin of bumpin the multiplier down to 9 and the fsb up just a tad if it will work. my vcore is still at 1.85 and my temps have risin with my case sides closed up to about 46 idle, not too bad but still not too great.

sandra, motherboard monitior and bios all rate my cpu 10 degrees C less than Asus Probe on A7V133! I was worried until I realised that Asus was outvoted. My CUV4X seems consistent with Asus probe and other software monitors though (same version).

I've got a couple of them,

#2 DURON 600 @ 1110MHz ASUS A7V133 1.92V Global Win FOP32 + four case fans. 49/53C load

I've read that the ASUS Probe reads temps as much as 10C higher than actual. Mine are running rock solid, I watch the temps more for an unexpected rise in the readings than the readings themselves.

well i downloaded sandra just to do some checking (hehe, i have wcpuid, sandra, and asus probe all running right now) and ive found that asus probe v. 2.12.07 on my Asus A7V 1007 reports the exact same temps as BOTH my bios and sandra. it also reports the correct fan rpms and core voltage.
I just bumped up to 9x105 and im at 41 deg C without my case on, not bad. Another weird thing i have noticed is that my voltages are always 0.4V higher than they should be by the jumper, so my max voltage WITHOUT the voltage mod is 1.89V, kinda interesting i think.

There's one thing to keep in mind when using any onboard monitor, that's the placement of the probe, which can vary readings quite a bit. The ASUS boards are notorious for high readings, as much as 10C, the SANDRA readings also come off that same probe.

10C too high? thats seems like a lot. what causes this, probe TOO CLOSE to the chip? how can it return data higher than the actual chip is?

I never gave that much thought, but the general thinking out there is that the ASUS boards don't give accurate readings, it has been written that they are as much as 10C higher than actual. Mine have run as high as the low 60's with no problems, but I still reworked the cooling to bring it down to at least the mid 50's according to their probe.

Its odd, your 800 should do a gig easy, maybe you just got unlucky. I have noticed one glaring thing in these threads and that is the fact that many of you are running your voltage much higher than you should have to. This will most definatly result in higher temps.

for instance:

Duron 750@900 @ 1.725 volts
Duron 750@850 @ 1.70 volts
T-bird 850@1050 @ 1.75 volts
T-birt 850@1000 @ 1.725 volts

Those of you having problems reaching the promised land should first see what your Cpu is capable of by means of just playing with the voltage and multipier. When determining its limits, then proceed to play with FSB overclocking as well. This way you can tell if it is indeed your CPU, or something else like your memory timings causing your instabilities.
Another little known fact is that every megaherts increase if FSB does not always neccesarily translate to increased performance. For instance, a FSB of 105 maybe faster than a FSB of 106. This has to do with the increments of "33" and its second level harmonics. I had a link to a sight that explained this much better, and I will try to find it.

A little bit of knowledge is a dangerous thing!<P ID="edit"><FONT SIZE=-1><EM>Edited by ncogneto on 05/20/01 11:39 PM.</EM></FONT></P>

Sandra actually says my core voltage is about 1.78 right now. I think thats a bit high, but i have my moboard set to "AUTO" .

I was wondering if you guys knew how to play with the multiplier? it never does anything when i mess with it. I also messed with the voltage. no change in anything. Im using jumperless setup on Asus A7v.
