Is it possible to run a Duron with 133fsb?
- Thread starter biggiesmallz
- Start date
Should be able to do it with all the chilly coolers out now. I may try with a 700 unlocked with the old pencil trick.
i originally had a Duron running on a 140 FSB, but had about 2.1v to the core, it is possible, just take more work then some are willing to put up with.
my last set up
Duron (Spitfire) 140FSB 7x
Abit KT7A-Raid with Voltage Mod
Coolermaster HCC-001 HS/F

Been running one with the stock cooler for over a year now. First it was on an ASUS A7V133 and now on an ECS K7S5A. Have not had a problem with it yet. Did not have to modify the cpu at all.

If you don't unlock the cpu, you're shooting for a 1.7ghz overclock since 13*133=1729. This overclocking speed is unrealistic with a duron (maybe you can mod the voltage & use crazy cooling solution (i.e., vapochill, dry ice)). If you want to increase the fsb to 133, you need to unlock the cpu. It only requires a steady hand and a cheap pencil. Give it a shot. If all fail, it would be a good reason to upgrade the cpu.
If successful, try the highest fsb as possible.I used to run mine at 133. I thought I had it at 166 mhz fsb for a bit, but I may be mis-remembering that. Hopefully you've got a morgan core Duron. You'll probably need to unlock it, unless you're very lucky.
Believe it or not I think I already unlocked it cause I'm overclocked now 800@950
Been over a year since I put I in.
I remember I couldn't get it to POST and I thought that the ram was bad but then I moved the jumper to 100fsb and it booted up.
I think I'm gonna try to lower the multiplier and raise the fsb.

Before I upgraded to an Athlon XP, I was running my 750 duron at 135 for just over a 1ghz. And that was with a cheap volacano 2 hs. Didn't have to change the multiplier as my mb would lock up if I went over 140. That duron only cost me $25 at the time, one of the best bargain upgrades.
So I'd say it depends on what model duron your talking about. If your willing/able to change the multiplier then of course....
Ahhh I remember what happened.
I remember reading an article that motherboards with fsb set by jumpers won't overclock on certain cpu's with certain factory set multipliers but jumperless motherboards will.
It was because as soon as you turn on your computer for a split second as soon as you turn on your computer the multiplier info from the cpu is used and if your fsb is 133 and you have a 850MHZ cpu your computer tries to start for that split second at 8.5 x 133= 1130.5 and therefore won't post.
But for some reason on a jumperless motherboard the multiplier and the fsb are set at the same time therefore it POST's with no problem.
Oh well

I have my server running an old Duron 600 @ 7.5 x 133.... all day long for at least a year now.
The only reason I have been thinking about replacing it is because I have a 1.4 T-Bird in a drawer... and I can't have that.
I may give it to the wife... she'll like that alot more than her ol' P3-600 she has.

I don't think it has to do with a motherboard having softmenu or hardware jumpers. According to this site:
The L6 bridges control the default frequency (multiplier) of the CPU. If you have a 200Mhz "B" type CPU then you may need to modify these to allow you to boot at 133 FSB or higher. For a brief millisecond at boot up, the CPU initializes at it's default settings (regardless of you unlocking the L1's) until your bios settings take over. Some 200Mhz CPU's may not be able to handle that brief moment of extreme overclocking; e.g. a 900 Tbird made to run at 9x100 is being asked to initially start at 9x133. To get around this you can modify the L6 bridges by changing the CPU's default multiplier. You may want to modify the bridges to a lower multiplier, e.g. change from 900 to 700. You can't go too low so connecting any bridges necessary to get a lower multiplier is preferable over having to cut a bridge or two. Here's a chart of the bridges and the multiplier settings from Tom's Hardware. You'll see 3 columns of bridges, the column on the left are the L6's. There is an article at Anandtech on the subject of the L6 bridges.
Actually it does since this problem ONLY happens to boards with jumpers. According to this article.
Pages 2, 3, and 4 basically explains it explains.
Page 2 http://www.anandtech.com/showdoc.html?i=1440&p=2
Page 3 http://www.anandtech.com/showdoc.html?i=1440&p=3
Page 4 http://www.anandtech.com/showdoc.html?i=1440&p=4
On page 4, you can read the following: "A fully jumpered motherboard overcomes the ?problem? in a similar way since, once again, multiplier and FSB are both set simultaneously - as soon as the board is powered on in this case. So far, the ASUS A7V133 and the AOpen AK73 ProA are the only examples of fully jumpered boards. Of course, the ASUS A7V133 can work in either fully jumpered or fully jumperless mode, and that?s why it shows up in both categories here."
Having a fully jumpered mode overcomes the problem. The problem does not ONLY happen to boards with jumpers. Rather the problem arises for the boards that are semi-jumperless or semi-jumpered (having both a jumpered mode to set between 100 and 133 and a jumperless mode to adjust the fsb once in the bios).
using a $20 duron 600 i picked up in the for sale forum, i hit 6 x 133 = 933 no problem at 1.75V. would also hit 1 GHz via 6.5 x 133 but i did not like to push it there (needed 1.85V). durons are really easy to unlock if you have to lower the multiplier as they are on ceramic--the old pencil trick works on them.
Mine did 154 fsb @6multi. Then the pencil multi-unlock failed, which leads me to believe that if I used rear-defogger paint instead of graphite, it'd be more stable. Brb, gotta get some paint!
700mhz duron@952mhz
136--fsb
1.85--vcore
36°C
pcmark 2002 scores:
CPU: 2698
MEM: 3632
HDD: 1095, but it floats @ 1000-1100 with both my xp1800 and this one so it's pretty irrelevant.
Just for comparison here's my axp1800+ score@ stock speed:
CPU: 4679
MEM: 3389
m/board is a7n266-c.
Pretty funny to see a Duron score higher than a 1.5ghz athlon in Memory!

What a hassle! I had to use a eency weency dental tool to get the paint in the right spots! Dries super quick too.
It says to leave it for 24 hr before turning on defogger. You think that goes for computer applications?
Anybody experienced problems with not waiting?
*edit*: [excited]I didn't wait. Booted right up @ 6x136! Wooooooohooooo! I'm gonna wait a couple hours b4 I push it though.
For those who don't believe the bit about 154fsb, I'll post a wcpuid. eeeheee![/excited]

Doh! You're right!
Here's the comparison with both @133 fsb:
AGOGA Palomino 1800+@1.5ghz / Duron 700@935mhz
-----------------------------------------------------------------
C-pew: 4679 / 2661
Memory: 3389 / 3564
HDD: blabla / hohum
Anyway, pics of 154 fsb from a Duron!! Hehe.
Also cool. And
SuperDuron!:Q

Your numbers don't add up. 6x133=798 and 6.5x133=864.5 according to my calulations.
You must have got them numbers from a Pentium based computer!

133FSB is actually about 133.3 ,though it depends on the mbrd
Btw I've unlocked 3 Morgan Durons & set them to all to run on a 133FSB
Duron 1.1GHz ,8.5x133=1.13GHz ,& 2 Duron 1.2GHz ,1 at x9 for 1200MHz & the other at x9.5 for 1266MHz

Hi everybody,
just got a Duron 800 and KT133A based mobo to play with. It's an AKCA Duron. Unfortunately the mobo doesn't support multiplier nor voltage or frequency settings. I will have to do everything by hand...
However, it seems that the normal Vcore (BIOS reading, haven't installed Windows yet, so couldn't check with Speedfan or MBM) is 1.69V. Since this processor should have a voltage of 1.6V it seems to overvolt. BTW, the mobo is a MSI K7 Turbo ver.3 (aka MS-6330 Lite 3.0B). The only useful jumper is the 100/133MHz jumper for the bus. The only thing I tried is to put the jumper from the 100 to the 133 position and it didn't work. Obviously the expected speed (8x133.3 = 1066) was to much for this setting at this voltage. Then I had to go to bed (working from the morning, and it was past midnight - maybe that's the reason I'm tired?)
Well, my basic idea is to start with the following (what would you recommend):
1. Just hit max voltage (options are 1.65V, 1.8V and 1.85V - since I don't want to cut any of the L7 bridges) and try out the 133MHz setting - well, since the mobo seems to overvolt - should I start with a lower setting (1.65V or 1.8V)?
2. If this wouldn't work - I probably would try out playing with the multiplier setting (L6 bridges). According to the table I could go to the multiplier settings of 7x, 11x and 12x. Obviously only 7x comes into play. With a setting of 133 MHz this should correspond to 933 MHz. I think this should be the minimum I should achieve with even lower voltage.
Oh, yes, the cooler is a new bought Spire Falcon Rock II with a copper inlay (should be enough for the Duron, even overclocked). The main issue is to keep noise as low as possible, since this is my wifes computer nad the Falcon is really silent.
Will keep you informed about what I will achieve.
