LOL

I think you got me there Jake ...

I heard of it a dozen times, but never used it or even saw it.

Thanx for the link !!!

Hi guys,

my P2B-DS goes up to 112MHz FSB without having CPU problems at 2.0V making the two P3s stable at 504MHz.

Bu tI have too many other cards plugged in causing trouble, hence I switched back to 103MHz FSb in order to put the PCI bus back close to spec.

...

Jake, what benchmark gave you those graphical reports ???
(link please, if possible ... thanx)

...

agallag, you should easily reach 112MHz FSB resulting in 504MHz core speed.
Depending on your MoBo's revision number you might even have a couple of more settings available (rev1.10 has more settings than the prior ones)

Okay, since I don't have my own website or a reasonable facsimile, I will try to improvise for the moment...

Replaced with better diagrams below!!

When I get some pics taken, I will see if someone can post them so you can get a better picture....

Okay, here we go... Let's try this....




And this....



Hope this works...

[Guyver]

Cool - it worked!

Yippee! - I know I'm a little slow some times, but that was my first post with pictures from what could be my first website....

- Gotta get out of the office more...

[Jake]

Thanks Guyver!

I love your pics!
I got myself an extra fan yesterday tyo bring my PIII som 600 Mhz lovin'. I will be fiddling with it later today. Stay tuned for an update later....

Here's the deal folks...

Yesterday I swapped my 192Mb (3*64) sticks of PC-100 for one Apacer PC-133 128 Mb stick. After installing it and running a memory benchmark in Sandra it look like this now:



How about that boost in memory speed!!! Slap my skull with a 2*4 and cage me up with an angry gorilla!!!

Anyway, I wanted to try out if my PIII- would do 600 like Guyvers little wonder. I installed a socket7 CPU-fan of good quality to blow down at CPU. I used plastic strips to hold it to the tower backplate (where the mobo is mounted). I still get the same kind of errors I got when I tried it with my old memory. It won't do 600 yet (Damnit).

So I guess it is still either a heat issue or maybe the clock divider for 133 is REALLY 1/3 as stated in the bios. I find this unlikely, as it also showed 1/3 for the 124 setting, when actually it was using 1/4. Sandra confirmed this (31 Mhz PCI and 83*2 AGP speed). It even lists the divider as 1/4 in Sandra!! Damnit again! (sorry)

A speed of 133 would cause my PCI and ISA bus to be Mega-OC'ed, with the PCI running at 44 Mhz. If this is the case my Quantum 6.4GB harddrive might give up. (Who would blame it at 11 mhz above PCI spec.)

The AGP speed however should stay would be the same as it uses it own divider of 2/3 (89*2 Mhz). Nomatter what divider it is an increase of the AGP speed of 6 Mhz as opposed to running 124. Could this be what causes my lockups at boot, with lots of graphical errors?

In a few hours I will take my PC over to a friends and install his Abit BX2 mobo in my system in stead of my BH6. This boards is able to measure the temp in the PIII core using MBM4. (Love Alex!) Then I will be able to determine if my CPU gets a dramatic increase in temp. when I try to run 600 or if it is my BH6 bios and it's clock dividers that's screwed up.

Stay tuned for the exiting (Yawn) sequel of my OC perils! (Don't touch that dial?)

Man, can I write a lot af BS!

L8r,

Jake

Older revisions of Sandra would just guess when they didn't know what was going on. It used to post completely false information about my SS7 system, because it hadn't been updated correctly. I would try to find some other program to confirm your PCI speed.

[Jake]

The saga continues...

Well, I managed close the gap toward 600 Mhz further today by testing my CPU in a frends Abit BX2 mobo, which supports more clockspeeds and a 1/4 divider (for certain) at 133 Mhz. I managed to get it stable at 129 Mhz busspeed, which translates to 580 Mhz. It would still freeze when I tried for 600.

By upping the voltage to 2.2 and pointing a huge table fan to blow cool air through the tower I managed to boot and run Windows 98 stable at 600 Mhz. Only problem was that somehow this disabled my L2 cache, making Sandra think I had a 600 Mhz Celeron III installed. LOL! The 'III' must be from detecting the SSE instruction in the CPU.

So getting rid of that excess heat must be the issue here.

As my CPU is fitted with a retail Intel heatsink and fan I have ordered a GlobalWin Dual fan MEGA heatsink. That should help me keep this baby cool. (I hope).

Now I'm faced with a small problem. Does anyone know how to disassemble a PIII-retail heatsink and fan combo?

It looks like it should be easier to take apart that the PII cartridge. If you know how to do it wihout breaking the PCB, post the procedure here please.

Jake

Over at The HardOCP site, there is an article on how to do it. With pretty good instructions and pictures. Wish it was around when I did mine, there way is much easyer.

Hey - one thing...

With my BX6R2 the best I could get was 129Mhz FSB. As soon as I switched to the BE6 .... BOOM -> 133FSB rock solid.

I later found out there were supposedly some technical issues with the BX6R2 and it's 6 piece buffer set, that made it mostly incompatible with PC133 HSDRAM and others.

Guyv.

[Jake]

Guyver,

That was an important piece of info, man. You just gave me some hope that I might actually pull this off and get to run 600.

I read a preview of the new BE6-2 called BF2 over at hardocp.com. It looks like the board for me.

Thanks again. I will get my heatsink monday.
Waiting in suspend mode....

Welcome!

[Jake]

Hi!

Well I managed to confirm that the BH6 ver. 1.0 does NOT support a PCI divider of 1/4 at 124 and 133 Mhz FSB. You were right. The board is equipped with a PLL clock chip from IC Works called W123, which supports 124 and 133, but only using a divider of 1/3. This sucks bigtime. That computes to PCI speeds of 41 and 44 Mhz. I must have some good peripherals installed on my PCI bus as everything runs nicely at 41 Mhz. But 44 might be too much for them to handle and that might be the reason why my system locks up at boot (that and the heat issue) at 133 Mhz FSB.

I gotta gets me one of dem BE6-2 boardsy thingies....

Anyway, I'm getting my GlobalWin cooler today (hopefully). Maybe that will help resolve the heat problem....

Regards,

Jake

Oh yeh, I total forgot about the CARD COOLER above the MAX, NIC, and sound card. Not a bad deal for cooling. Covers 4 slots, and moves alot of air.
