Celeron 1A at 1459 with intel fan and std voltage. but I need help

[arga]

I am using the MSI EPT Pro motherboard, and it is very confusing.
There is no way of knowing or choosing the PCI divider.
When running the Overclocking utility Fuzzy Logic 3, I read

Memory Clock 133 MHz
CPU clock 1459 MHz
AGP clock 122.0 MHz
PCI clock 60.8 MHz !!!!

According to this, the PCI divider is 1: 2.4 !!??
is this possible?
I have made all kind of changes, in jumpers or BIOS
and I can´t change the PCI divider!!
its always fixed at a ridiculous 1:2.4 at every FSB!!
I think this Fuzzy logic is crap!!

I have run CPUID and the FSB seems correct: 145.9 MHz

Is there any utility out there to measure the PCI frequency?


Also, the Celeron is running with stock intel fan, but this fan is quite noisy (4000 rpm).
I expected it to be almost silent. Well, perhaps its me, that was used to my silent Pentium 120 haha

Also, the heatsink lay upon the heatspreader with a sticker acting as interface. Is this correct?
Or shoud I remove the sticker? well, anyway, the sticker acts quite well, considering the 45% overclock

Also, I am using standard memory running at standard voltages.
If I use PC150 memory and rise voltages maybe this celeron can reach even higher

Another detail: I am using a PCI graphics card. No AGP.



ok, thats all. remember to answer this question: how do I measure my PCI frequency?

None of that makes much sense. I think the MSI is like a TUSL2. 133 and above, you get a 1/4 PCI, 1/2 AGP. 132 and below, 1/3 PCI a,d 2/3 AGP. Mem should be able to go 133FSB/100 mem or 133/133.

Ditch that fuzzy logic stuff. Set your FSB to 145 (if that is what you want), the PCI and AGP will be set automatically. Dont use the 133/100 mem setting. It will give you a HUGE hit in performance. Run it at 133/133. Run 2-2-2 if possible.

If your 1.0A will run 145+ FSB stable @ default VCore, you have the best 1.0A I have ever seen (by far). Most need 1.6 -1.7 to get to that speed!

The stock fan is actually 3400 or 3600 RPM (I forget) and is about as quiet as you will find. I'd say ditch the thermal sticker and replase with some AS-II or III, but it seems to run very well the way it is. That 1.0A HS is pretty small. Keep an eye on your temps!

I hope the PCI divider is set to 1/4 , haha... otherwise I am frying my PCI cards!!
but I have no way to find out ...
about the memory speed, the fuzzylogic says 133, but it should be also 145. And
it is set very weirdly in the BIOS: you choose 100 or 133. instead of 0,+33. Of course
I have chosen 133, but I have noted that the fuzzylogic doesn´t react to my election
of memory speed in BIOS.

The CPU fan reads 4066 rpm in fuzzylogic, but perhaps it is another error...
what is clear that the noise is annoying because it is high pitched. I didn´t expect this.
I have bought an ultrasilent Samsung HD (80 Gb) but it is useless as long as this Celeron
is so noisy. I will try to stick a 80 cm Papst fan ontop of the Celeron if I can do it well.

The thermal sticker... yes, its incredible, but it is not being a problem. And the heatspreather
is not a problem either. I feel weird, hehe. Perhaps I am reading wrongly the FSB too?
As I said, I have used H. Oda´s CPUID 3.0, and it reads 1459 Mhz too.

Could you post all the info about that CPU? Stepping, batch, Philli or Maylay, etc?

 

[arga]

Do I have to remove the heatsink to see that info?
A couple of hours ago I have done so, to replace the noisy fan by another more silent
but I haven´t paid attention to the inscriptions of the chip, sorry.
I have noticed, though, that the termal interface has been slightly damaged
so I wouldn´t like to remove the heatsink again unless strictly neccessary.
I am looking at the box and there are a sticker with a lot of numbers:
Prod Code, MM#, EAN,FPO#,UPC,VERSION# and PACKDATE.
But no place of manufacturing.
Wait, I am going to post a screencopy of the CPUID...

[arga]

well, I guess the link doesn´t work.

here are the CPU ID data:
Brand: 3
Family:6
Model: 11
Stepping ID: 1 (Standard)

Internal clock: 1459.08 MHz
System Clock: 145.91 MHz
System Bus: 145.91 MHz
Multiplier: 10

@ arga

look at the sticker on the box.
The interesting numbers are the FPO# and the Pack date. Please post them here.

I think from the FPO# you can tell also where the Cely was produced. When comparing all the numbers a FPO# beginning with a 7...... should be a Phillipine and beginning with a Q........ should be a Malaysian chip.

My Cel 1.0A (Philippine boxed) isn´t that good. No go at default voltage with 133 FSB. I have to use 1,675 Volts. Then it runs stable up to 136 FSB with the stock fan and TUSL2-C.

I want a different 1.0A so your numbers on the box would be interesting.

What do you think about the MSI EPT Pro motherboard. What´s the voltage range with Tualatins? I have to build a new system for a friend and my choice of boards are limited to the the Asus and MSI board as I can´t get any other here. I liked the MSI Athlon boards but never had a MSI 815 board.

Also I´m not that happy with the TUSL2-C. I have to run my old Coppermine Celly with a higher voltage in compare to my Abit BH-6 but I´m not sure if it´s the motherboard design or the chipset.

FPO#: 7144A347 (phillipine then)
PACKDATE: 01/17/02

about my MSI board:
Vcore is adjustable from 1.475V, 1.500, ... up to 1.600V but I haven´t tried to modify the default 1.475
Vio is adjustable: 3.4V,3.5V,3.6V (I only tried the default 3.4V)

The MSI board is very confussing if you want to play with FSB, PCI and MEM frequencies.
In fact, I think you only have freedom to alter the FSB. The rest are decided by the motherboard.
Even the MEM frequency! I am not sure if you can run it at +33%.
The Fuzzy Logic III application for overclocking is USELESS and it shows wrong PCI, and AGP frequencies.

But in spite of all this, it allowed to overclock my 1A Celeron up 45% with default voltages and fan.
I also tried to push the busses with FSB=125 and everything ok!

I am having problems with a PCI satellite TV card, but I don´t know what is to blame. In fact, I was
thinking that perhaps the ASUS TUSL2-C wouldn´t have these problem.

Also, note that I am using a PCI graphics card, not AGP.

The ASUS TUSL2-C allows for IRQ assignation to SLOTS in BIOS, I think. The MSI doesn´t allow that.
I don´t know if this feature may be useful when you have IRQ conflicts.

>>>Also I´m not that happy with the TUSL2-C. I have to run my old Coppermine Celly with a higher voltage in compare to my Abit BH-6 but I´m not sure if it´s the motherboard design or the chipset. <<<
I don´t think it is the chipset 815 EPT. For me, the chipset worked fine. It is weird that you are having these problems with your TUSL2-C.

You have no idea how good a chip you have. Most 1.0A's need ~ 1.65 - 1.75 to get to your speed. You have a newer CPU than I have seen so far. Could you please post this info @ Overclockers Forum? There are a lot of people there that would be very interested to hear about your CPU!

You MSI worls like a TUSL2. 133 FSB and up sets the PCI to 1/4, AGP to 1/2. Below 133, PCI is 1/3, AGP is 2/3. Mem speed is the same as the FSB speed. There is no "+33". That is a VIA thing. There is a 133/100 mem setting which means a 3/4 mem/FSB relationship. 133/100 = 133 MHz FSB/100 MHz mem. 150 FSB/112.5 mem, etc. This causes a HUGE performance hit. Don't use it.

 

[arga]

ok, I will post this info there.

and about memory, so there is no +33% , but instead a -25% setting?
how weird. yes, I won´t use it.... or perhaps, I will use it to relief the
memory and see how high the CPU can go. My memory is standard PC133,
so it is probably being the bottleneck now. If I can set memory at -25%,
then it will be relaxed.
Anyway, I have installed a slow fan on top of the CPU, so it is hotter now
and it will be more difficult to reach higher.

and now I am more worried with other problems: my satellite receiver is not
working; I am making a lot of tests and reinstallations. Well, I don´t have much
time for overclocking

Try wiring the VID1 and VID2 pins together to get a higher range of voltage adjustments. I did this and now I can feed 1.8v to the CPU and reach a FSB of 153MHz with my retail chip. ID: 7135A789-0144 SL5ZF
