Running 200 at 266?

[13oots2]

I have an ARGA 1000 Athlon that runs at 200FSB, the new MoBo I have will run the RAM at 100(200DDR) if I use the standard settings for the CPU. What is the likelyhood that I will be able to run the CPU at a 133(266) bus and a lower multiplier? Memory bandwidth is the most important factor.

No problem at all as long as you lower the multiplier enough so the cpu is not over its mhz limit.

Thanks for quick reply, hope that my RAM arrives this morning. Have more than a little to learn today, actually have a MoBo that's overclockable:)

I myself have an Athlon 1.2 AXIAR-Y running at 200 FSB. Was just wondering, is it possible to run this chip while setting the FSB jumper in the board to 133? I have an Epox 8KHA+ and I did that once. Lowered my multiplier to 9x. All I got was an 'FF' in the Debug Post. Didn't boot at all. Black screen. Reverted back the jumper to its 100 FSB jumper setting.

Watchuguys think?:)

As stated above. You should have no problem, provided that your motherboard will run at 133 (the original KT133 chipset wouldn't) I've got two DURON 600's that will run at 133MHz+.

Which motherboard do you have, more importantly, which chipset does your motherboard have?

Good Luck!

Epox 8KHA+ running on Via's KT266a chipsets.

Thats odd. Hmmm, will check it out again when I get home. Thanks for the info, FRANK!:cool:

Have just got a Gygabyte 7DXR with AMD 761. Why you say 1) It was cheap. 2) Never had problems with Gigabyte:)

First of all, Welcome to the forums.

That being said, I had a similar problem with my new 8KHA+ myself. The following is a reply I made to a post in the "AMD motherboard" section;


>I got my 8KHA+ on Mon. I had problems at first, but I can't blame the board.

I had a problem that I've read about on other sites, it POSTED the first time, but when restarting after recognizing the hardware it just wouldn't POST, fans only, no video, no beeps etc. I took it down to nothing and started from scratch.

I had heard about somebody having a problem with his board bending one of the CPU pins. When I removed mine to check it, I found a chipped corner on the core of my 1.2G T-BIRD. I replaced it with an AXIA 1G and set everything back up, I haven't looked back since.

The strange thing is that I've installed the chipped 1.2 on my A7V133 and it runs great. I presently have it running at 1.4G with no problems.

As far as the soft boot problem with this board, I've had no problem in this regard. The only "quirk" I've encountered is a bit of flickering on my monitor during boot, once into Windows this problem disappears.

The Sandra memory benches are great (806/1031), this board scores 40%+ better than my AD11 with the AMD761 chipset using the same memory.<

I've read about some people having problems with various PSU's, the generic ones and Enermax in particular, although others disclaim this. Some also suggest this board is picky about RAM, I can't confirm this.

I would suggest taking it apart and reinstalling just the basics that you nee to POST with, CPU, video card and RAM. Make sure that everything is seated correctly.

I know how frustrating this is, I wish I could tell you more.

Good Luck!



By the way, the reference to the KT133 chipset was directed to the other post.

The Epox 8KHA+ uses the newest VIA chipset, the KT266A. I'm running mine at 161FSB right now.

Thanks Frank for that insight.

I have to agree with you that the board is a really great overclocker despite the quirks that happens with some of its production units. Luckily, I haven't had a problem that can be attributed to the board. Thank goodness.

Will check that jumper again when I get the chance. Might shoot down the multiplier a lot lower to see if it would work. Really wish it would. Overclocking my chip with the jumper set at 100 doesn't get me too far. Besides, I need to get it to run on the 133 jumper so I can take advantage of the 1/4 PCI right?

Will keep you guys posted on how things will go. Thanks -- seal

Yes, you usually need to get to about 132 to take advantage of the 1/4 divisor, I was looking for the 1/5 that has been talked about so much. I can get to 162 and apparently haven't found it yet. I wasn't able to find the PCI bus speed in Sandra, can't boot at 164, so I don't think it's there.

If I only need to get to 132 to take advantage of the 1/4 PCI divisor, does that mean that I really dont need to fix that FSB jumper in my board? All I would have to do then is set my clock speeds to 133 and see if the PCI divisor worked?

Does your Durons run on 133++ without changing the FSB jumpers in your boards to its 133 setting?

You can easily put a 200FSB on a 266FSB Board they all have jumpers to switch between the settings.... choosing a 266 board is excellent for upgrades later!

I found that when trying to jump my settings from 100Mhz FSB to 133MhzFSB, system would fail POST. But when I slowly raised the FSB and rebooted each time, ie 112, 124, 133, etc. I had no problems and the system is rock stable. However this is easier to do with my Abit KG7-RAID board which allows 84Mhz to 200Mhz in 1Mhz incriments. I had to ease over the AGP and PCI multiplers.

Yes just unlock the cpu in the L1 bridges and then set it to 7.5x133 to start and you should have no probs at all
