How far will my 800E go?

[Pace]

I've got P3-800E on an Abit SA6R (after muchos problemos ) and it says SL4MA on it - would I be 100% wrong in thinking that I've got a cC0 stepping?

Would I also be wrong in thinking I can get near 850MHz without glitches on stock cooling?

I would think you should be able to better than 850 with stock cooling unless you have a bum chip.

S-spec SL4MA = cC0 stepping, so you would be 100% correct.

Woohoo

So, I'm running at about 848 I think (though 3DMark2000 tells me quite a bit over that ~870 I think). I'll get WCPUID and check that.

When using ATi DVD player I get lots of glitches in playback - like I see frame 1 between frames 2 and 3 - if that makes sense.

I'll try PowerDVD and let you's know how I get on.

WCPUID: 8 * 107.53 = 860.20MHz - yet gives flickering in DVD playback.

Edit: I went back to 100, then up to 106 again which fixed it - that's just one part though

Right...er, hmm...

I'm at 108 FSB in the BIOS, which WCPUID says is 109.02 (giving 872MHz).

At 110 I get an error from my SBLive (BSOD re: emu10k.blah) so is this the PCI spec causing problems?

The system is as above, plus:

Sparkle TNT2 32Mb (only running at 2x)

IBM 30GB 75GXP
Pioneer 10x DVD

Thanks,

I recently installed a p3 800 in my brothers system(cco stepping)and i was quite pleasantly surprised when i was able to overclock it to 960mhz(120 fsb)using nothing but the stock heatsink/fan that comes with it and also using stock voltage.

Not bad at all,considering his board is an old asus p2b-f and it's still using generic pc/100 sdram.

I can only imagine how high i could get it with better memory(pc/133)and bigger heatsink/fan for the cpu... .

Very far if you throw it off of The World Trade Center

I found the output of stupid ATI DVD player to be a bit choppy as well and had much better luck with the Radeon and Power DVD. I often have problems getting ATI products to work with other ATI products. I'm sure "ATI's engineers are looking into the matter."

By the way, at 800 MHz, the DVD output on my G400 Max is quite spectacular. I know the board was taken to task quite a bit for not supporting this feature or that. And it doesn't score well on Mad Onion's benchmark (because it doesn't have this feature or that). But at 800 MHz and with Power DVD, it didn't seem to need any of the missing features. Output seems to be as good as my Radeon at 733 MHz and every conceivable feature.

So there.

Paul: I'm using a TNT2 - and if only I had enough money left over for a G450!

That's what's due for an upgrade next anyway, maybe March would be a good time

So, do you's think it's my other components which don't like the non standard PCI/AGP speeds? Should I get a PEP66 or something, and go for a 133 FSB (1.066GHz)?

I think a small increase in voltage would be in order. Overclocking issues are hard to predict, but I've never seen a Soundblaster Live that couldn't handle a 36 MHz PCI bus. Usually, it's SCSI cards and hard drives (very serious!!) that fail, and they tend to hold up pretty well these days. That doesn't mean it hasn't happened. I just haven't seen it. Generally, however, it's your CPU or RAM that's causing the problem.

I'd up the voltage on the CPU from 1.70 to 1.75 and see it that stabilizes things. Above that and you should start thinking about cooling issues and nice heatsinks. With some motherboards, it is possible to further tweak the I/O voltage as well.

I just would never recommend anyone try for a 133 MHz with a PIII 800 MHz. The mulitplier is very high. This is one of those personal decisions. The PIII was not designed for these speeds (AMD changed that), and it becomes all about voltage, cooling, and luck. Unfortunately, you'll have to spend more money to find out.

Personally, I don't think having problems at 110 MHz is a good sign. However, we're in ALBPM, Greebe, Kruzin, and Maggi territory now. I'd wait for the Beta Boys to chime in.

Happy New Year Paul!

yes, 8x124fsb should be possible(cBO chip) so I expect cCO chip should do so as well. if memory serves me correctly, one murcer claims in his specs to have gotten 8x133fsb with his abit bx133 board!

[DuRaNgO]

tweak the voltage and go straight for 133, get some arctic silver compound if you can

How much memory and what type do you have in your system??
If you're using more than one 128MB DIMM put them in slots 1 and 3. This is one of those odd things with some ABIT mobos.

Can you adjust the I/O voltage with with the 815E based mobos??
I heard you loose that ability and it would be better to have this up to 3.5 or 3.6 volts for overclocking.

Can you set the AGP Clock Divider to 2/3??

Also disable Spread Spectrum Modulated.

As far as heatsinks go you will only get the PEP66 to fit with modifying the fan shroud.

So, you may want to consider the PAL35t or a Hedgehog with a copper shim instead.

I find that this sometimes prevents reaching the highest stable OC possible. Try it one way, then the other as it doesn't seems to follow any specific chipset/MB type or brand.

In theory, this should improve OC ability and mine is set to ON, tho this is an Athlon (6167) 750 chipset MB.
