duron on KT7A 7.5 133/33

Sil3nthill · 16th July 2001, 2:18 PM

I finally unlocked my duron 850, and since i didnt have good cooling i just decided to go from 850 to 1gig.

So i set it at 7.5 133/33
and i started gettign random freezes in windows, i dont think its heat since sometimes it freezes and i quickly reset and its only 40C in bios.
Then i went to sisoft sandra and it said my agp bus is running at 88mhz and my PCi was too high as well.
But i thought the 133/33 spilts it a normal agp and pci bus speed?

Now my Pc seems to freeze randomly..eg after 4 hrs or 30 min.Its not overclocked at all.
Can this happen if i pencilled the bridges wrong?

aussie7 · 16th July 2001, 9:03 PM

I'm an AMD novice so I mite not be much help, just got a Duron 800 and Abit KT7A combo up and running.

Unlocked it by using a hb pencil to connect each of the L1 bridges. After I removed the glue from the warantiy sticker and cleaned the surface around the L1 bridges.

So far got it at 7 x 133/33 @ 933 1.65v ok so far, havn't tested it yet or seriously tried higher.

I would suggest

instal the latest KT7A BIOS from abit (make sure you set your duron to default speed to insure stability during bios flash)
http://www.abit.com.tw/

install the latest 4 in 1 drivers from VIAHardware.com website
http://www.viahardware.com/download/index.shtm#4in1

Hey aussie7

when you set ure cpu at 133/33 what is ure agp and pci bus speed runnign at?
sandra said my agp was at about 88mhz and pci was high too, im not exact about the figures, but sandra did say it was very high.

aussie7 · 17th July 2001, 10:10 PM

Sisoft Sandra 2001 Pro Performance Wizard, under Mainboard Information.
I got the same result AGP bus speed is too high. Reduce FSB.

I disabled the 4x AGP in bios, kept crashing with it on. Using a Hercules Prophet II MX 32mb dual display card

I haven't had much time to work out what the bios settings are yet.

I don't know how to set the pci divider and assumed the 133/33 means 133 fsb and 33 pci. Will have to do some searching to find out about adjusting the AGP speed.

Sil3nthill · 18th July 2001, 11:01 AM

so 133/33 makes the agp higher and pci higher??

hmm then whats the correct splitter?
i need my agp and pci normal go get my system stable

since its stable at 10x100
but 7.5x133 and it randomly freezes.

Hi

I found the anwser in the FAQ Section > Overclocking > Does altering "CPU FSB Plus (MHz)" in SoftMenuIII affect my PCI and AGP bus speeds?

On "Paul's Unofficial Abit KT7A" site http://www.viahardware.com/faq/kt7/kt7faq.htm

Does altering "CPU FSB Plus (MHz)" in SoftMenuIII affect my PCI and AGP bus speeds?
Yes. The PCI clock of KT133 based motherboards is fixed to 1/3 of FSB until the FSB is set at 135MHz (unlikely on a KT133!) after which it is set as 1/4. With KT133A motherboards the PCI clock can be 1/3 or 1/4 of the FSB depending on whether it is set as 100MHz or 133MHz. The AGP clock is always fixed to be twice the PCI clock. So no matter how the FSB is changed, the PCI & AGP clock will be changed according to these fixed ratios. The KT7 user's manual states that this option allows you to "independently increase the CPU FSB speed". This statement is misleading: the PCI and AGP bus speeds are affected. (Confirmed by ABIT)

Hope this helps Sil3nthill

I have the same MB, with a 750 Duron. I have it at 7.5x133, using the 133/33 FSB setting in the BIOS. It runs stable at 1.85V.
I used Sandra 2001 to check my PCI/AGP speed last night, and it said they were 33/66.

I have a TNT2 Ultra, with 4x enabled. I think from memory there is a 'force 4x AGP' option in Integrated Peripherals, you might want to check that is Off. Also check your emeory settings. I set all mine to Turbo, with a latency of 2.

Maybe it's due to the BIOS. What version are you using? I think mine is the latest, ZY (or something). Might also be different vid card/PCI cards. I also use a SBLive.

westicals · 18th July 2001, 2:14 PM

The reason that SiSoft Sandra says that your AGP is at 88MHz, and your PCI is at 44MHz, is because the version you have cannot successfully recognise the KT133A, so it assumes you have a KT133, which does NOT have a 1/2 Divisor for the AGP, or a 1/4 Divisor for the PCI, so don't worry your AGP and PCI busses are running in spec!! About Random Freezing, It could be your ram, or try upping the IO and Core voltage a tad

Sil3nthill · 18th July 2001, 6:58 PM

Hmm its not my ram i have kingmax pc150...but im using cas2 4 way interleving etc etc.

unless its my temps...it runs about 48C on high load...but the thing is the during the times it crashes i checked the bois and its only 39C etc.
My voltage was at 1.75, i didnt want to go anyhiher just for a 150mzh overclock.
But now i installed the latest 4 in1 via, and not one lockup although its at 10x100.
I want to run at 133mhz but im scared my agp and pci will bite the dust!!
So u guys are sure on a KT7A the 133/33 option sets the pci/agp at normal speeds....my sandra is wrong??
And i havent updated the bios at all, how do you check the version anyway?

Damn i really want to run at 133, my mem bandwith goes around 550 compated to 470 on 100.

133 should be perfectly fine...the dividing would be 133/4 = 33.25 for the pci clock which is perfect, and the agp would be 66.5 or so which is also the normal

i wouldnt really bother updating the bios....my kt7s still running the now 9 month old bios..=p....and it works perfectly

as for memroy..as i got a kt133(not an a) im maxed out at a 118 mhz fsb.....i (used to....before my new ram) get 617/654 or something like that..=p

aussie7 · 18th July 2001, 10:15 PM

I agree that it is Sandra not recognising the KT133A, When I checked in Mainboard Information Sandra 2001.1.7.10 Pro It reports the following.

Extende Mainboard Data
> Chipset - Via KT133

System Chipset
> abit computer corp VT8363 KT133

AGP Bus
> Bus Speed - 88Mhz

PCI Bus
> Bus Speed - 44Mhz
> Speed Multiplier - 1/3x

I even uped the FSB to 135 and sandra still reports my AGP @ 88Mhz and PCI @ 44Mhz

I am going to update Sandra and see what it reports.

Currently running Duron 800@1000 7.5 x 133/33 @ 1.8v stable in 3D gaming and in Sandra Burn-in Wizard running continuos loops.

My Sandra 2001.1.7.10 Pro scores

P3 700@933 Abit BX133-RAID 128mb PC133 cas2 Apacer/Infinion
CPU 2517/1256

Duron 800@1000 7.5 x 133/33 @ 1.8v Abit KT7A 128mb PC150 Kingmax tiny BGA
CPU 2795/1364

scores higher than my old P3 700@933

Squozen · 18th July 2001, 10:26 PM

Don't worry, dude. If your PCI bus was at 44Mhz you likely would have found your HDs were exploding.

Sandra is known to be a bit flaky unless you're using the latest version - are you?

Just installed the latested version Sandra 2001.5.8.11 Pro and now reports Chipset KT133A, AGP 66Mhz, PCI 33Mhz, Multiplyer 1/4x

GOD · 19th July 2001, 2:09 AM

don`t raise your I/O voltage ant 133/33.
because it is running at standard fsb.
what u need to raise is your vcore.
since durons were made to run at 100fsb,133fsb is really overclocked quite high.

and get a better cooling for your chip.
in the bios it might read 40DegC.
it is probably about 10degC higher in the core.
and which bios do u have???
i suggest u try the ZT1.11+ (modded one).
very good and stable,+ extra options.
u can get them at PAUL`s unofficial ABIT KT7 faq.
or here.
