BE6-II?

[Jedi]

Alright...I have this board and a new 733 (133fsb) Coppermine slot 1. The board itself is rated at 100fsb so I flashed the BIOS to UH so that it would accept the new speed and fsb settings of the new CPU.

Well if I try and select any fsb speed of 133 it won't POST. If I change the Multiplier it lists a different speed upon start up (Currently I have the BIOS set to user define w/ it set at 110x7 and it reads a 550cpu speed)

Right now I'm just trying to figure out how to get it boot at the CPU's default speed, 733/133. OC'ing will come later.

My hardware is this:
Santa Cruz Sound Card, Vision Tek 64 GTS w/DDR, and a Linksys Networking card. The CPU is cooled by a Gorb as well as 2 80mm panaflow case fans in a push/pull setup.

Any suggestions on why I can't select the standard 733/133 setup in the BIOS?

I think the BF6 BIOS is about the same - there was never OFFICIAL support for a 133 FSB on a 440 chipset - check your divisors for AGP and PCI clock - if I remember right, one of them cannot be set to a rational speed, so this may be your problem. On my BF6, I believe it's the AGP that can't be set to anything lower than 2/3 ; therefore making it an 88 MHz 2x AGP bus - it should be closer to 66. Youch! Anyone correct me if I'm wrong - this is coming off the top of my head at work :)

Good luck with the OC

Well I did download the BIOS from Abit's website and they do have a couple different ones for 133fsb support so I just took the newest one. I will double check the PCI and AGP settings, they can be changed in my BIOS, and see if that makes a difference.

Firstly, make sure you know which BE6-II you have, there are three versions and the bios is different for the earlier boards. If you can see it there is a label on the ISA slot that gives the version. The other way to tell is to see what type of HTP chip is on the mobo. The Abit site explains it all. Now make sure you have the correct bios for the version BE6 you have.

Your cpu is really P3-550E disguised as a P3-733EB and should be capable of doing 850Mhz. Be sure your AGP is set to 2/3 and your PCI is at 1/4 for 133fsb and above. Just try booting it with only the video card (which should OC no problem) and go into bios set-up and check your cpu temps to make sure they are not too high.

I have also read posts where some cpu's refused to boot at 133fsb but were fine at 130 or 140.

sorry its v1.0

Well I went back through and I have the fsb up to 120 but I noticed that changing the mulitplierdoesn't do anything. I moved it from 5.5 to 11.5 and no change of CPU speed.

Aren't the multipiers unlocked ? Anyways I got it running at 660now better but not good enough.

Hey Luc Skywalker,

--->> The clock multiplier is locked. It's set in stone so even though you think you changed it, it wont take effect. Your CPU is stuck at its clock multiplier at 5.5 so no matter what you do in the Mobo, the clock multiplier will always be at 5.5

Go in the BIOS clock frequency setting option and look for the 733mhz setting. If you can't find it, then find the "User Define" where you change the mhz frequency setting in the BIOS and manually set it to " 5.5 x 133". This really should work. I owned Abit BE6-2 Version 1 before and I know what I am saying here. Even with the original, ancient, old BIOS, you still can change the FSB mhz, and has the same AGP/PCI ratio options as the newer versions of BE6-2. Good luck and have fun.

BTW, since your CPU is at multiplier of 5.5 yours will unlikely be able to overclock as high as the P3 700 CPU because the 700 has the clock multiplier of 7x. If you got the lucky overclocking chip of 733, then you might be able to overclock pretty damn high but dont count on it.

This will not work with any PIII I've ever heard of - it's basically impossible to unlock the multipliers on a CuMine cored chip. Some ppl claimed to have, but I'm convinced they're crackpots who are having fun at others' expense. :)

Ok the multiplier isn't a big deal, its a bummer though. I did select the 733/133 option in the BIOS but it won't boot up. I will go try manually setting it though but so far 133 fsb is evil on this board.

[[OC]_SR20DE]

hmm... have you checked and make sure that the AGP ratio is at 2/3 and PCI ratio at 1/4 as what LimeyGreg had said? .. and can you tell us what Vcore voltage is it running at in the BIOS when you set it at default of 733mhz? The Vcore voltage should be set automatically from your processor so you should not have to worry.. but just check and see what's the voltage is running at. And also, raising the I/O voltage by 1 notch if it still doesn't boot windows.

[LimeyGreg]

Jedi, read my previous post again. As I said before, remove all your cards except the video card and get into the bios at the highest fsb you can. In PC Health check your cpu temps. Post the temp and the Vcore voltage. Forget about the multiplier setting. Do you know what s-spec or stepping your cpu is. Is the CPU a Slot 1 or is it a FCPGA on a slocket, and if so what is the make of the sloket ?

all this talk about 550 is nice but you want it at least at 733! Well the Abit BX133 overclocking guide that came with my mobo suggests the following settings; (I adjusted some of them for your cpu) go into your BIOS setup and set the following;

-Softmenu III Setup-
CPU operating frequency: "user define"
CPU FSB clock: "133"
CPU Muliplier: "5.5"
Sel 100/66 signal: "default"
PCI clock/CPU FSB clock ratio: "1/4"
AGP clock/CPU FSB clock ratio" "2/3"
AGP Transfer mode: "normal"
CPU core Voltage: "1.80"
I/O Voltage: "3.80" (is what's needed on my mobo to get to 133FSB)
In-Order queue Depth: "1"
Level-2 cache latency "default"
Spread spectrum modulated "disabled"

-Advanced Chipset features-
SDRAM RAS to CAS delay: "3"
SDRAM RAS precharge time: "3"
SDRAM CAS latency time: "3"
SDRAM precharge: "enabled"
DRAM data inegrity mode: "non-ECC"
System BIOS chachable: "disable"
Video BIOS chachable: "disable"
Video RAM cachable: "disable"

Your PIII733 should boot with these minimal settings! If not you have a real problem and should get another CPU or another (official 133FSB) mobo. If it boots up and is stable, try setting the in-order-queue depth back to "8", and see if you can lower the I/O Voltage. I think the iBX chipset needs a high I/O voltage to do 133 since it's a 100Mhz FSB chipset. Well good luck with trying out these settings, and let us know if it worked out or not, ok?!

Sorry to interrupt your "post" but I felt compelled to say hi to Limey Greg, and by the way my BE6 II 1.0 could never boot at 133FSB, 132 and 134 were just fine.

Alright. I removed the sound card and Network card and it will only boot up at the same fsb speed, 123.


My temps were 33c and the Vcore voltage was 1.82 according to the Hardware Doctor. I did try uping the CPU core voltage to 1.8 but it still wouldn't Boot into Windows.

As for the CPU it is a CuMine 733 Slot 1 Model 8 Stepping 3.

I think I will just RMA the board and pick up a standard 133 capable board.

Lancelot I tried your settings but it would hang up at the Windows Splash Screen. I tired upping the voltage 1 more but still no go. Thanks though.

[LimeyGreg]

The reason I requested you remove the boards was to make sure they were not causing a problem. The reason for requesting the cpu temp in the bios is that it gives a good indication of whether your HSF is too small or incorrectly mounted, your temp looks okay. It is unlikely your memory is the problem as even generic PC-100 will usually run at 133 fsb.

I would be surprised if it was actually the board, but that is possibility, albeit a small one. I tend to think your CPU is the problem. If you can, get it exchanged for another, but try to get an 'E' rather than an 'EB' as they have more headroom for overclocking. If you are going for the 'EB' you are better off getting around a 1GEB.

Hi Howard, nice to see you on the board and thanks for the confirmation on the 133fsb anomalie. :)

I have to second that! I have never been able to boot in at a fsb of 133 with my BE6-II v1.0! 132mhz, as well as 134mhz and above but never 133mhz!

[mrpcman]

Me to. I had a v.1.0 board that couldn't do 133 either, but any other setting would work.

Hey Jedi, have you had any luck yet? If not, maybe try flashing to the XU bios as it is the latest release for the BE-6II rev1 boards. While I may be running a P3-700, my board, a BE6-II rev1, will boot at any fsb setting up to 150. (Need better cooling, otherwise I'm sure it would work.) If it doesn't help sorry, just my thoughts.
