***Trustly old Abit BH6 now @ 1.57 GHz! Slot 1 owners come on in***

[lifeguard1999]

Like Zap I have a P3V4X. I just ordered the Slot-T and I will be a bit more adventurous by trying to overclock a 1.1 GHz Tualatin (100 MHz FSB) to about 1.46 GHz (133 MHz FSB). We'll see how it works out. It would be nice to get 1.5 GHz (136 MHz FSB) out of it.

All this is assuming, of course, that a Tualatin in a Slot-T will even work with my motherboard.

 

[Assimilator1]

I know THG used a slocket & a S370GU (before Slocket T was out) on the P4V4X without problems as I recall

Also you mbrd is listed as being compatible ,I would say you have nothing to worry about ,let us know what speed you get out of that baby

Hmm, I didn't check back here in a few days, and there's been lots of activity....

One person (W1zzard?) on the overclockers.com forum said his 1.1 BH6 died, but I don't remember if he was using a SLOT-T or not. He didn't follow up with information. I'll go back and check. He might have been using the original mod.

I haven't seen any more reports of 1.1 BH6's dying, but several about 1.0x boards.

By the way, there is another mod, posted by "Cemal" on the same forums, which involves no bridges, just insulating 7 pins, and a bridge only if AK36 (?) isn't connected to ground on the slotket. He says that this MOD is much better, as it does not risk any short curcuit between vcc and vtt, and keeps the voltages in spec, and running cooler. The original mod causes the voltages to be out of spec, risking cpu and/or board short/burnout.

I wanted to get a SLOT-T for myself, but I'm still trying to see if anyone else has had the boards die after using a SLOT-T.

And, if the slot-T doesn't cause any problem, this directly according to Upgradeware, then why did Stephen M's board die?

Of course, I saw another post (might have been on the abit NG, but I don't remember) saying that someone's BH6 (1.0x) died after running a P3 1 ghz in it....blown mosfets. And that wasn't a Tualatin.
I ran a P3 1000EB @ 1125 + MSI Master 2.3, for a year, with no problems, and before that, a 600e @ 900. (FSB=150 in both cases), but obviously I have a 1.1 board.

 

[lifeguard1999]

Thanks Assimilator1! From the list I see that a slot-T is support on a P3V4X Rev 1.02 and above. I have a rev 1.02 board so it looks like I am set.

 

[Gonad the Barbarian]

I have one of these running a 1.3 in a Soyo 6VCA if anyone is interested. That mobo will allow async RAM/FSB speeds so I'm running the 1.3 at 100 and the RAM at 133.

 

[Assimilator1]

I'm going to run a 1.1A GHz in a 7VCA which I guess is the S370 equivalent of your mbrd?? ,I'm going to run the FSB-RAM ratio 1:1 because I'm going to overclock it

Antos
When I eventually get the Slocket T for my 6BA+III I'll let you know how it goes, if it helps

 

[Mark R]

My trusty BH6 is screaming along at 233 MHz.

I've got the CPU up to 300 MHz before - 4.5 x 66 and 3 x 100, although my RAM can't quite cope with a 100 MHz FSB.

Not the best board I've owned, but it worked, and still does - more than I can say for my other Abits - which haven't worked properly from day 1.

 

[RickH]

Any more toasty BX's to report?? Hope not. R

 

[bacillus]

just ordered a slot-T to try with my p3b-f board!

 

[Zap]

Like Zap I have a P3V4X. I just ordered the Slot-T and I will be a bit more adventurous by trying to overclock a 1.1 GHz Tualatin (100 MHz FSB) to about 1.46 GHz (133 MHz FSB).

Not more adventurous than me I already have two 1.1@1.46 (Abit VH6T and just recently ECS P3S6AT) and a 1.2@1.6 on an Abit BX133-RAID. I have a total of THREE CPUs sitting here waiting for that Slot T to arrive, 1.0, 1.1 AND a 1.2 (not including those other three I mentioned). I ordered the slot T a week ago (bad time to have things ship). Soon as it gets here.... I will no longer have the slowest computer at work.

 

[lifeguard1999]

Sigh

FedEx delivered the Tualatin today (3 business days from when I ordered it).
UPS is saying that they will deliver the Slot-T on Monday or 6 business days from when I ordered it. So much for UPS's 3 day delivery.

Sigh

 

[Warlock!]

I received my 2 converters and boxed retail 1.4 Celeron CPU's today.

My problem is I can't get either one of my systems to boot using the new CPU's.

One MB is a Asus P3B-F ver 1.04 (was a P2-333 @ 66mhz buss), the other is a Abit BH6 (was a Celeron 300 o/c to 450).
The Asus will power up, but I get nothing on my monitor.
The Abit will power up and freeze after completing this line.
-MMX CPU 98MHz

I have tried setting the sockets to 66 & 100MHz buss speeds and tried voltage ranges from 1.3-1.5 with no difference.

I can't change any of the Bois settings once the new CPU's are installed because the systems freeze.

Should I be setting something in the Bios before I install the new chips?

BTW both units will power up just fine with origional CPU's back in their slots.

The power supplies are generic no name brands that came with the case. (250 watt)
Supposedly they were rated good enough to power an AMD 1+ somehting GHz CPU. I can't recall their exact rating it's been a year.
I would think if the power supplies were the issue, I would at least be able to get to my Bios screen on one of the units.

Any suggestions? I'm looking for my hammer right now.

I have a beefy PS on my tower system, but I would prefer to save trying that as a last resort. (now where is that forklift?)

Oh BTW are you folks replacing that thin thermal strip and using AS2 instead?
I don't plan on o/c'ing these 2 beast's, I just want good stable systems that my kids can use for HW & gaming.

 

[oldfart]

The P3B-F should work fine. I dont have one handy, so I cant say for sure how to set the BIOS up. be sure you have the latest BIOS first.

For the BH6, either put the old CPU in and boot up, or clear the CMOS. Set the Slot-T up for 100 FSB and 1.5 Vcore (default settings)
Set the BIOS up for
100 FSB
Multiplier does not matter (I used 12x)
Vcore = auto
Speed Error Hold = Disabled
The BH6 should have SS BIOS if it's a 1.0x, or SP if it's 1.1 or higher.

I always take off the thermal tape and replace it with ASIII, but thats me.

Thanks for the help.

I tried and still no luck, it freezes everytime.
The bootup screen display's bios version FL
I'm not sure what rev the BH6 board is, where do I find that info? <edit OK found the answer to that, could they put it in a worse place?>
Also you said you use 12x multiplier? In my bios screen the max is 5.5
I'm guessing that my first order of business is to upgrade the Bios.

 

[RickH]

Up grade the BIOS?Don?t worry about the multiplier it set by the CPU automatically. R

 

[oldfart]

I'm guessing that my first order of business is to upgrade the Bios.

You are correct!

 

[Assimilator1]

I'm guessing that my first order of business is to upgrade the Bios.

It does say on the upgradeware website to use the latest bios!

Re your Asus setup ,you have at least got PC100 RAM right?

****************

Btw folks more bad news about Abit mbrds in general!

I got this email from upgradeware

Thanks for the information.

In some Taiwanese/Japanese discussion forums, some Abit users (SA6, VH6, SE6.....) has reflected that capacitors has serious "blown" (the tops of capacitors stick out ) problems, such as "JACKCON" brand capacitors. Hence, Abit Taiwan offer free "replacement" for those poor quality of capacitors. If capacitors are bad quality, they might possibly killed your board. Because of this, Abit's stock price had dropped a lot. Please take a look for the following links for the "blown" capacitors of Abit boards.

The 1st link is in Chinese so not much help there ,but there are a few pics.
2nd link is dead for me

My fathers old mbrd an KA7 blew the caps after just 18mths (last spring),:disgust: ,unfortunatley I didn't know about the above so I just binned it.Shame really as it was otherwise a good mbrd.Notice 1 of the pics in the 1st link shows a KA7.

It seems that Abit have a general trend of fitting bad caps ,at least until the recent past .
It looks like the Slocket T is in no way to blame for the failures but a combination of an old mbrd,poor caps & a heavier current load from the higher clocked CPU's result in many early Abit BH6 mbrds dieing.

Some PIII Slot1 Katamai & Coppermine current loads (taken from Intel PIII datasheets ,p28

450 MHz 14.5A + 1.08A for L2
500 MHz 16.1A + 1.21A for L2
600 MHz 17.8A + 1.45A for L2
600 MHz 13A
750 MHz 15A
933 MHz 17.7A
1.0 GHz 19.4A

Some PIII Coppermine current loads (taken from Intel PIII datasheets ,p31 )

500 MHz 10A
750 MHz upto 15.7A
933 MHz upto 18.8A
1.1 GHz 22.6A

Some PIII Tualatin current loads (taken from Intel PIII datasheets,p26

1 GHz 19A
1.2 GHz 20.6A
1.33 GHz 23.1A

Well this is very strange ,the PIII's Ts with 512k cache use less current according to the datasheets ,p27 ,you'd think with more cache it would use more current ,maybe they've got the numbers mixed up! (or did they revise the core slightly?)

1.13 GHz upto 19.9A
1.26 GHz upto 21.2A
1.4 GHz upto 22.4 (wth? )

Some Celeron Tualatin current loads (taken from Celeron data sheets,p26 )

900MHz 18.1A (never saw that model!)
1A GHz 19.1A
1.1A GHz 19.9A
1.2 GHz upto 21.5A
1.3 GHz 22.5A
1.4 GHz 22.6A

Some Celeron PGA & FCPGA current loads (taken from Celeron datasheets ,p27 )

300A MHz 9.3A (no difference with cachless version either )
466 MHz 13.4A
533 MHz 14.9A
533A MHz 11.4A
766 MHz upto 16A
950 MHz 19.4
1.1 GHz 22.6A

So as an example ,going from a Celeron 466 to a Celeron 1.4GHz results in a 69% increase in current load! :Q (not bad for a 300% increase in clock speed though )

My SH6 had the JACKYCON(sp?) capacitors and they blew up 18-months later. I had no idea what it was, because my computer was just rebooting itself over and over after loading XP. It would do it 5-times in a row and then would be fine for the rest of the day until I shut it down and let it sit for over 30-minutes. I thought maybe it was my RAM or power supply!
I didn't figure it out until I opened the case and noticed the tops of ALL the larger capacitors were swollen and bloated.

I thought about replacing them myself since that's a super easy job for someone who can solder, but Abit replaced my capacitors for free so I didn't worry about it.

LOL. You mean you don't have a case window on the bottom of your tower, to see the outer edge of the outermost ISA slot?

Seriously, I know exactly what you mean. I had a BH6 for ~4 years, was in and out of that case a dozen times to swap memory, CPUs, drives, etc...I think I just now saw that sticker for the first time when I finally swapped my motherboard out after all these years.

Also, one more thing to try...I had to lightly pinch the little blue "wing" things on the top of the slot-t adapter to get it to seat all the way into the slot-1 on my BH6. There was a small bit of friction between the slot-t and the original cpu retention device (black towers).

[oldfart]

Its easy to tell if you have a 1.0x or a 1.1. 1.0x has white printer, serial, PS2 ports. The 1.1 and up are colored.

On the two BH6's I was working with...way back in this thread...they are both 1.01. The one with the 50n03 MOSFETs is a 1.01 rev G. The one with 45n03 is a 1.01 rev E! I wound up giving the rev G board to my friend since I didn't want to take the risk on the rev E board. I'll use it for another project. The rev G board has been running very well for him with the Tually 1.4 GHz. He was a little nervous about it so I left it running @ 1.4 Ghz, 1.3 Vcore. I had it running 1.57 GHz 1.35 Vcore and I'm sure it would be fine there or higher.

I bought a new Soyo TISU 815 board to put the now homeless C1.4 in for $60. I'll probably run it @ 114 FSB for a nice round 1.6 GHz.

oldfart, is your cpu the tB1 stepping version?

 

[oldfart]

I think so. SL68G.

just checked & that's a tA1 stepping.
can't seem to find any tB1 steppings on this side of the pond!

 

[oldfart]

tB1 steppings are good ones? I haven't been able to push one of these yet since I dont have the proper mobo to really do so. The fact that I got it to 1.57 GHz with an undervolt was pretty good. I would think 1.7+ GHz would be pretty reachable. I'll see how this one does in the TISU. I think PCI frequency will be an issue though.

 

[bacillus]

it's just my observation but folk with the tB1 stepping seem to get a better o/clock using less voltage than those with tA1.
