Just updated the first post of the thread with the data collected. Have a look!

DIfferent apps tend to report different values... what do you have it set to in the BIOS?

Wow, is the vcore reported in cpu-z right? Are you really running 9x333 @ 1.168v? What is your vcore in your BIOS and is it prime95 or orthos stable? Mine won't do it on less than 1.232v in cpu-z (which is 1.2625v in the BIOS).

If you own a Q6600, please reply with your VID and the stepping of your chip. The VID can be found using coretemp . If you're using vista, coretemp will not display the stepping in some cases, so you can use CPU-Z (it's listed under "revision") to get the stepping. Here is a shot of mine for referen...

Good idea... I was thinking about plexiglass... do you have photo of what you made installed you can post? Also, is it just held in place without a support or did you rig up something to hold it there?

You ever post those pics? Plus it looks like you removed the fan from between the PSU and the hardrives in the lower bay... how did you do that? I don't see way to without breaking it.

Interesting idea to compartment off the video board w/ a piece of cardboard... I wonder if there is a better choice of material for that though... one that isn't flammable! Anyone got some ideas? I will say that it is pretty darn effective. Usually my X1950 Pro raises my NB temps by about 4-5 °C si...

Becuase that won't always work when overclocked.

Not true. I have all the power saving options (i.e. speedstep, C1E, etc.) enabled on my Q6600/P5B-Del machine and they work just fine@ 9x333.

No, I leave it on auto. Idle 1.16v, load 1.26v. Is it too high or what? For that chip I don't think it's too high. I would point you to this thread. Have a look at the results that only 0.120 V can make on temps for a q6600. I would recommend that you also follow the orthos or prime95 stress testin...

This is one of the easiest mods you can do to your P5B-Deluxe (and probably any P5B although I haven't tested it on any model but the Deluxe) to help you get higher voltages under load conditions and also lower your idle vcore; it is particularly useful for people wanting to get more juice to feed t...

1.26 is your auto vcore? Did you try to minimize that?

@HT - Looks like my card doesn't like being pushed even 10 % over the factory setting of 590/770 as it hardlocks my system when I do so. Dunno if mine is a poor sample, or if this is standard for the X1950Pro.

Maybe I need a different o/c util?

graysky, I lapped both heatsink and CPU, and I can concur with yr results. Both my heatsink and CPU surface were concave initially. Yr coretemps improved by abt 6-7 degrees, mine was 5. Which means u probably had better technique! I'm gonna wait for my AS5 to settle in, hope it drops by another 2 d...

The 300h; is that 300h of usage? Surely not 300h of lapping! How long did it take all up?

300 h of usage It only took about 1 h or so for the lapping. Doing the chip was cake compared to doing the HS.

Yeah I did and yeah a tech from TR told me they are convex by design since most C2D/C2Q chips are convex on the average. Lapped it completely flat and got the modest ~2 °C drop. If you look at the thread I referenced where I lapped the IHS on the chip, you'll see the largest drop occurred from doin...

Cool, now I just wish I could overclock the thing wo/ the monitor going black.

All I know is that 'auto' mode for chip vcore gives the thing way too much mvolts. I have to assume the same overestimation is true for the other voltages as well.

@woodsman: good catch w/ regards to the error (I just corrected it).

I've been using ATITool a bit and found that my screen goes black when I tweak the settings. I don't have a flat panel; it's a CRT and I'm using that DSUB-->DVI adapter if that makes a difference. BTW, what are you using that reads the fan RPMS? ATITool 0.26 just shows % power for the fan. Anyway, t...

Right you are... I actually lapped it a few days later and wrote up the whole experience in this thread.

I just bought one of these (256 meg version) and am wondering if my temps are normal.

Room temp: 75 °F
Idle temp GPU: 40 °C
Idle GPU environment temp: 35 °C (this also agrees with my NB case temp)
Load temp GPU: 60 °C

Thanks for the info all.

Sounds pretty simple, but you'd be surprised how many people don't know about how much vcore can affect your load temps. Temp and frequency (FSB) have a linear relationship whereas temp and voltage have an exponential relationship. Conclusion: minimize voltage. Here is the Intel document that helps ...

I recently started to remove the "auto" setting from some of the user configurable voltages in my P5B-Del and noticed that not only is my system stable to 2x orthos for >2 h (and still counting, I'll probably stop it after 6), but the "system or chipset" temp as measured by speedfan (Winbond W83627D...

I was curious just how much room temperature can affect the temperature of the PC. I chose to look at the CPU since Speedfan can monitor and log temps for each of the 4 cores in my Q6600, and since of all the components, the CPU is probably the most sensitive to changes in air temp. since mine is ai...

Well, after lapping my HS, I've had this nagging little voice in my head telling me to do the same from the CPU. I did the job with 800 grit sandpaper. Initially, I told myself I'd just buff what's there right now just to see if it's level. After about 30 laps in one direction and 30 in the other di...

When my Ultra-120 X and I have to say I'm a little puzzled. The base where it should contact the heat spreader is not smooth at all, it's actually grooved! You can see a scratch which is where I gently ran my thumb nail over the surface; I could feel the rough edges. Have a look for yourself: http:/...

Anyone? I know what to do with my older nforce 2 board to enable the HLT cooling via wpcredit: Row 60, col. 0F change "0F' to "1F" but how about the proper setting for this on an nforce 4 board?
