Mhz drop??

[qgshadow]

i would like to know what make the mhz drop at a certain fsb?? its not the temperature cuz they're ok...

someone know why my mhz drop?

[.sentinel]

What temp in Farinhiet.

[saaya]

either the chipset/board sux and the higher you psh the fsb the more the fsb varies reasulting in the mhz of the cpu jumping up and down, or the cpu is running too hot...

you keep saying temps are fine, but you also said there was some bug about the temops that were reported.
so im not sure if the temps are displayed as ok, but in fact they are higher.

those pentium d chips run HOT, so maybe asus changed the termal probe readings so the temps look better and people dont get scaredof the high temps...

maybe my board is broken...
is the asus rma support any good? are they fast, are they sure to change my board?

[saaya]

better rma to the shop if you can!
rma to the mfg usually takes a long time!

have you disabled ci and speedstep.looks like your multipler may be changing? mine did that in the begining,after i disabled a couple off things in the biose its working 4.8 all way through. its couse intel has inplanted a new future to keep the cpu at lower mhz when not needed.thermal control also needs disabling.

aaight what im suppose to change in the bios?

[vanovich]

all mine are set to disable .Execute Disable Function: AUTO
Enhance C1 Control: AUTO
CPU Internal Thermal Control: AUTO
Intel SpeedStep Tech: AUTO
though when disabling these you want be able to use throttle watcht.only part

I experienced some of the same problems. It seems that some part of the LGA775 CPU's have a impact on the memory controller (northbridge) and the higher rated the CPU is by stock the better quality is this component.

I had a Pentium 4 520 2,8GHz - the cheapest model. It ran 3,5GHz (14x250) at stock voltage - increasing the FSB 1MHz over the 250MHz FSB would result in a fluctating FSB/clock frequency. Above 260MHz FSB it would go totally crazy. I thought this was a motherboard failure, but after trying both Asus P5P800 and Abit AS8 I confirmed it wasn't.
Now I have a Pentium 4 630 3GHz and it runs 4,1GHz at 1,35v on a Asus P5WD2 Premium. Going futher for 4,2GHz the FSB starts fluctating resulting in a unstable clock frequency. No matter extra vcore applied or other voltages it doesn't help (like the P4 520). I have installed Service Pack 2 so it's not the "4200MHz issue".

Then I observed that LarsK who started off with a Mach2 GT cooled P4 660 had switched to a P4 670. First I thought it was crazy - a expensive price/performance upgrade, but then I found out that it was because that he got a tip that the 670 would handle high FSB speeds better and it did.
If I remember correct his 660 that ran 5GHz (~18x280) and it started getting crazy at ~14x330MHz FSB (only ~4,6GHz) and even lower with 4 dimms populated (4x512MB). His 670 runs 14x390MHz FSB (5,4GHz) with 4 dimms populated (4x512MB) with no problems, but it daily runs 5,1GHz or so due the Mach2 GT unit can't cool the CPU enough.

So I'm telling you... there's something in those LGA775 CPU's wich have a random quality and Intel know since the expensive models scale best.
My problems with the P4 630 @4,2Ghz I can tell is not related to the motherboard since a lot of people run a lot higher FSB's without problems on P5WD2 Premium - for an example LarsK. I say it's CPU related!

You got the cheapest CPU of the 800 series and thereby the CPU with the badest quality of the component that causes these problems.
Isn't you CPU clock frequency rock stable at lower FSB like ~250MHz?

now im at 3.8ghz 270fsb stable. i just put more voltage on the mch and fsb and everything lol...
just added voltage on everything and i can overclock higher ill still testing to get higher...

i saw like 2-3 D820 at 4.2ghz stable... 4.2 is 1.4ghz overclock!!

[qgshadow]

i got this screenshot at 3.7ghz i think
