Pentium D 805

Well i got my new Heatsink today was very proud of it, its a huge *****. its a Thermaltake Golden Orb ||.

I clocked it too 3.6 and runs fine, but when i get it too 3.7 or above and try running super PI it crashes

any ideas on why?

at what fsb? What memories do you have and how have you set them up? (multiplier,voltage).
It could be that the processors needs a bit more voltage, or that say the memories have overclocked much more than they can hadle (which could be solved by ovevolting them a bit or lowering the mem multiplier).

please refrain from swearing

Sorry, about the swearing. WHen i clock it it doesnt effect the Ram, im using Clockgen because i have nothing else to use , IE motherboard doesnt have anything. WHen i clock it to 3.7 the FSB is at 185.54, which i have no idea what that means.

It does effect the RAM speed, as overclocking the FSB overclocks your RAM too.

What RAM do you have and at what divider/voltage/timings is it set at?

I'll have a look at what timing's im using for my ram later, im on a school mac atm. How do i know what divider i am using? And also when i clock it using Clockgen the Ram doesnt change it increases the FSB and the cpu speed but it keeps the ram at 199.9mhz

Im running two sticks of DDr400 512mb, i dont think the timings are the same due to i got the second one later. I can swap them both for two identical sticks if it helps.

If they have different timmings they will just work with the values of the slowest module.
It would help if you tell us which motherboard you have.
In clockgen did you select your motherboard's clock generator? (its in PLL Setup)
Its importart to know at what specs your h/w is running and temperatures.
Even if you overclocked it at 5G if your processor overheats it will throttle down so you could have worse performance instead of better.
Your fsb should be fine. Your memory though, if its not really stable at
400 it will be way off. Try this, go to the last booting speed, like 3,6G and
try running memtest86 for an hour or 2. See if you get any memory errors.
Them run Orthos or some cpu stress utility to see if you get cpu errors or your cpu overheats.
You will need a floppy or a rw cd for memtest and boot from it. Here are some links:

I have an Intel D101GGC motheboard i have to use clockgen as i said, i am running it on PLL ICS 950405, i didnt exactly use this one cos a site said so i used it because it didnt crash. How do i run memtest when my cpu doesnt get overclocked until i boot windows?

Okay just tried the TAT but it didnt support my CPU and orthos and will set ti off tonight

To run memtest you have two options, #1 you download the ISO and burn it on a cd rw (so that you dont waste it afterwards) and boot from cd
#2 you download the self extracting floppy image, instert a floppy , run it and boot from floppy
If you have Vista, there is already a memtest utility available in the bootload menu. So is for some linux distros like ubuntu.
Someone that knows intel boards could help you more. I have no clue.
I think they dont have oc in bios except if you have an extreme edition cpu.

Strange that it doesnt support the cpu, actually it reports mine as Pentium M (but its a c2d)... maybe they dont support the program anymore who knows.
Anyway you can read temperatures with CoreTemp and stress cpu with Orthos then

i had PCWizard2007 running at one stage i reported it to them that the AUx temp and the CPU temp were the wrong way around for my cpu but im not sure if they fixed it ill have a look now.

@dkarko: is the program Memtest86+ (v1.7)? that's the currently active incarnation of the program.

Okay jsut got PcWizard, and seeings though my computer has been on for more then 24 hours straight and running orthos for the past 10 hours i doubt my core temp is 22 Degrees Celcius ill check it to bios

kappage · Post by **kappage** » Fri May 25, 2007 7:24 pm

It seems that they havnt fixed it yet, because in BIOS my cpu is running at about 50 Unclocked.... and in pc wizard Power/Aux temp is 50.

kappage · Post by **kappage** » Fri May 25, 2007 7:31 pm

Clocked at 3.6 running Orthos the temp increases rapidly heres a screeny. But as soon as i stop running Orthos it jumps back down to about 52

@Dan: Yes thats the one. But still it doesnt support all chipsets, but it will run anyway in that case.

I dont know the safe temps of Pentium Ds, but this is hot anyway and it cant be very far..
Is your case ventillated correctly? I'm afraid that if you want to overclock it more you will need watercooling.
See here:
http://www.tomshardware.com/2006/05/10/ ... age13.html
Seems you need to overvolt to get past 3,7-3,8 and with the temperatures you have you better forget it.. Plus they recommend watercooling to be able to reach 4G. Your temps seem marginal to me.
Anyway, read through the entire article and you will get the idea

After reading up on the whole Pentium D range it seems that it running at 60 C while running on high load when clocked is a "low" temperature for the Pentium D range. Ive clocked it to 3.6Ghz running otheros and using Everest Ultimate edition trial to show me my temps, (it actually works, after like 7 others).

Heres some results

Its done poorly while being unclocked

Its done quiet well it out performs my friends Pentium D 840 who gets about 20-22 seconds, as an average

and according to Everest Ultimate my max temp is about 65 Degrees

Try using speedfan to monitor your voltages while testing.

By what you had showing above, it's looking like you're running into PSU's cross-regulation failures as mentioned HERE --> 12V is droping down while 3.3V and 5V gone up.

kappage · Post by **kappage** » Thu May 31, 2007 2:23 am

So your saying it wont clock any furthur because the 3.3v is going up and the 12v is going down?

I'm saying --> The voltage shift patterns you had above indicated PSU failures from hitting maximum PSU power limit.

I'll not be trying to explain further than this as most PSU "experts" I ran into never seem to have any clue, they had never heard of cross-regulation tests, nor bother to mention it in their reviews.

I have no idea why that should be so, as cross-regulation test was and is what all PSU manufacturers had used to determine their PSU power rating since before the first IBM_PC was made.
