Checklist for running BX board @ 133

[Criminal]

a cpu that will run @ 133 fsb
a 1/4 pci bus divider
PC133 or PC150 ram
a video card that can do 88 agp bus (Geforce2)

anything else missing?

All depends on your hardware, But for the most part your right. I've seen a lot of PC100 ram run stable at 133mhz though. It helps if you up the I\O Voltage a bit sometimes.
My BE6-II would ran stable for a long time at 140mhz FSB. This with all the hardware I have below. Only with a PIII 600E, Awesome little chip!

One thing though, With this V5 I have to disable the winme or win98 (depending which one I'm running) splash screen to get it to boot into windows while overclocked. Weird! But with it disabled it runs great and boots up everytime.

I used my PII 400@560 fsb= 140 with no problem on my abit BE6 wiyh Voodoo 3 3000

uh, people have said that maxtor HD's don't work too well @ high bus speeds, but I've had serious problems with it.

A 1/4 PCI divider on a 133 bus would give you 33 mhz, that is what the specification calls for. He said he has this on his board.

I read that GF 2's, whether MX's, Pro's or Ultras won't run on many popular(or formerly popular) 440BX mainboards. Including BH6's and P3B-F's. I didn't want to take a chance with this, so I got a GF 256 instead. My P3B-F is happy with the Elsa Erazor X--89 Mhz AGP is no prob.

[Criminal]

really? i thought that it was the other way around. the original geforce series needed more power than the old motherboards can provide. the newer geforce2 needs less power. my geforce2 mx works just fine on my old bx board.

I ran a Prophet GTS 64mb , then a Prophet ULTRA for a total of 5 months on an ASUS CUBX ( P III 850@1190mhz ...140FSB) 92mhz AGP , and no problems what so ever.

hey mrpcman dude,

Some of the Seagate HDs do very poor job in stability when overclocked also. Like mine, it's a medium grade, Baracudda 7.2k rpm.. It gets registry corrupt at 133mhz bus WITH 1/4 pci ratio divider. Seagate SUX. hehehe..... but once you get it back running from the registry retrieval, it works very good. I will never buy HDs like Baracudda again.

Well you know, I work for Seagate and I've got a ST38421A in my rig as well as a WD and have absolutely no problems with it in regards to overclocking. Is it slow? You bet. It's old and it's a regular IDE drive, what do you expect. But to say that all Seagate's drives suck would be an unfair and very general statement. Did you know that a large % of the personal video recorder products have Seagate in them? Did you also know that the X-box will have Seagate in them also? (See here: http://www.seagate.com/cda/newsinfo/newsroom/releases/article/0,1247,815,00.html ) The only reason I went with the WD was it was on sale.
Flame on.......

I've had my Maxtor for about a year and a half. It's always been on an overclocked system with no problems at all. Now my Quantum which is only about 7 months old is slowly going out. It power's down every now and then, and cause system lockups sometimes.

I also ran with no problems overclocked with a V3 3500 for a long time. I didnt run into any problems untill I got my V5. But disabling the splash screen is a very small price to pay for the added performance of overclocking! So it's not a big deal.

First of all, my Seagate Baracudda model # is ST 310210A, that is ATA66 support @ 7200rpm. It is not a "regular" IDE drive. It is so-called EIDE or ATA-2 in this matter. I get a score of over 19000 on HD benchmark on a Sisoft Sandra so I don't know about you say being slow, LOL... Like I said once it runs, it runs. Why would I buy a cheap crap HD for? I haven't... but I now noticed this ATA66 Baracudda is very disappointing not being stable at 133mhz bus and UP when COLD BOOTING

yeah.. I see that you got pissed because I said "seagate sux", hehehehe... dont let it get to you.. okie honey? I'm an exaggerator. what can I say??. That is me. LOL but you surely do pre-assume easily about things. My damn Baracudda HD sux and that is it. Nobody is going to stop that. hehe.

About you mentioning the Seagate contributing their technology on X-Boxs for built-in HDs... heh........ what is so special about that?. X-Box is the downgrade from PC gaming industry. I dont find X-Box's is that Eye-appealing. So that is no challenge for the Seagate to do such. They dont need very special HD's to run X-Box.. what are they going to use??? a SCSI 15000 rpm with extremely high cache size transfer on a X-Box?? yeah right!!!! you make me laugh LOL... To be honest, Im not pissed.. Im just stating what I think I should respond. But yeah.. I admit. It is wrong for me to say "Seagate Sux". Sorry on that part.


Oh by the way, is that all you can do on your P3 700@ 952?? Maybe that's why your HD's not having problems? what happen to 1050- 1100mhz? LOL sorry, I couldn't help myself.

What a great thread! I am thinking about buying a PIII for my BE6 II in the next few months. I am running a 667 Celeron II at 1 gig right now. I heard that Matrox Millennium G400-450 cards overclock well too. I am going to try my current STB Velocity before I buy a new video card for this purpose. I also heard that most fo the newer video cards will handle the higher FSB. I am hoping that anything with an Nvidia/Riva chipset will do the job. I have come to realize also that CAS 2 gives a noticeable increase in system speed, I had to up the I/O voltage to get my memory to run at CAS 2. I am low on cash right now and do not want to pay for CAS 2.

Can someone explain how some HD will not works for OC@133+? Does it have to do with PCI or AGP?
How?

Some older BX motherboards don't have a 1/4 divider for the PCI bus. They only have an automatic 1/3 divider. So at 100 mhz bus speed you get 1/3 of 100mhz=33.3mhz, this is what the spec. calls for. If you turn your bus speed up to 133mhz with a 1/3 PCI bus you get 1/3 of 133=44.3mhz. This is too high for most PCI devices, especially hard drives.If you have a 1/4 PCI divider on your board, you can run at 133mhz, and your PCI speed is 1/4 of 133mhz=33mhz, or in spec. again. Hope that explains it.

[Robert]

Meaning that HD is also under PCI?
I though only PCI cards.

[DocClock aka MadClocker]

Yep the hdd's ride on the pci bus,
and I have had so-called caviar drives crap out after six months, and I have been running Maxtor drives ever since, and every machine I have put them into was overclocked past 140mhz bus except this new one I built for a freind, that has 4 maxtor's in it, It runs at 133mhz. I do however recomend hdd cooling, if you have the room, as the 7200's run rather warm.
Maxtor doesn't quibble over whether you bought the drive OEM, or retail boxed, they service them all, as long as you produce your receipt, and it is still under warantee

Thats funny mine works great

[zeisel]

i have 3 hd's, maxtor 15gig, WD 10 gig, Seagate 8.6. out of all these drives the maxtor is crap, cant go past 140 w/ 1/4 divider. seagate goes corrupt over 150fsb and my wd is just fine up to 160fsb.

[*spazzed*]

How do you disable the windows splash screen?
Thanks in advance....

[batboy]

Just a note to confirm that high PCI bus speeds do effect harddrives. I've scambled a Maxtor 40 gig 7,200 rpm drive once by overclocking too far out of spec (trying for 157 FSB). I reformatted and all was well again. Lost a bunch of data though.

It's the controller that actually runs off the PCI bus, which is then connected to the harddrives and CD-ROMs (floppies too). If I have a lot of CD burning to do, I usually back off my FSB a notch or two for added stability. Not all harddrives tolerate overclocking as well as others.
