Need help with SOYO 7VBA133U

[Brundle Fly]

Okay, here's the prob, I have a pair of unlocked Tualatin 1.26's, they run at 1.26/133mhz FSB/9.5 multiplier. I got this Soyo mobo because the FSB is clockable to 255mhz, in 1mhz steppings.

Once I slapped one of my Tualatins in it, I realized the multiplier is not adjustable, it sits at 4, which makes my Tualatin show up as a 533. Pure crapola, even on my old DFI mobo, it showed up as an 866mhz, which is stock/default, 6.5 multiplier, at 133mhz.

I was able to run these Tualatins on my old DFI board at a 9.5 multiplier, but not stable(bad caps on the CA64 TN).

My question(or questions to be more exact):

Any guru's out here in the Anandtech forums? My DFI mobo had switches to set the multiplier, there are none on this Soyo board, but I do see some jumpers, although there are no pins on them, so swapping a "jumper" is not an option, it would have to be hard-wired.

So, here's a couple pics of the "jumpers":

The first is the jumper connections themselves, I'm sure these control the multiplier

jumpers1

Second, their postition on the board, RAM slots above, socket to the left, Northbridge to the lower part of the pic.

jumpers2

Does anyone have a clue as to whether or not these are the multiplier jumpers? If anyone does, do you know which ones I'd have to "jump" to get a multiplier of 9.5?

All and any help will be much appreciated

Bumpity bump bump.

Man, is there no one here that wants to take a shot at this?

Anyone?

Even a link to where I can hunt down some sort info on the jumpers, I'm getting nowhere with my own searches.

I somehow doubt I am some kind of "pioneer" when it comes to OC'ing this board. Maybe the guys that have figured out how to adjust the multipliers are older farts like me, and don't hit these forums.

Sad when the guys who started all this OC'ing stuff disappear.

Soyo's site might be good.....

 

[Brundle Fly]

I've already emailed them, going on two months, no reply, probably because said mobo is discontinued.

Thanks for the reply, I'll try them one more time, but I do believe it's a waste of keystrokes, it was the last time.

 

[LTC8K6]

The manual doesn't tell you what those jumpers are?

Ah I see, I misunderstood those pics. You'd have to rig those.

 

[LTC8K6]

You should be able to set it in the BIOS. Assuming you can get into the BIOS.

If you've tried that, then I don't know what else you can try. If they are really unlocked, then the BIOS settings ought to work.

It doesn't mention those jumpers at all. As you can see from the pics, it's not like I can just move a "jumper" to the next connection.

I'm at the point where I'm going to buy a Mach Speed, but the FSB only hits 166 on those. Damn, I want to push this past 166 on this SOYO, but if I can't get the multiplier to to 9.5 to begin with, it's a lost cause on this mobo.

There are no settings in the BIOS for the multiplier. I bought this mobo because the guy who sold me the pair of Tualatins recommended it, he also thought there was a way to change the multiplier on this mobo. He was limited by a 166fsb, and thought this was the king of the Tualatin boards.

Turns out, that's not the case.

7VBA133U User Manual

3-1 SOYO COMBO SETUP

This Motherboard does not use any hardware jumpers to set the CPU frequency. Instead, CPU settings are software configurable with the BIOS [SOYO COMBO SETUP].

The [SOYO COMBO SETUP] menu combines the main parameters that you need to configure, all in one menu, for a quick setup in BIOS:

CPU Frequency Setup
CPU Frequency Select
Frequency 1MHz Stepping (66~255MHz)

Also check that you are running the latest BIOS

Ayup, I know that already, I already mentioned the FSB is adjustable, it's the multiplier that I need to adjust.

These are "unlocked" Tualatin CPU's, default is 866mhz@133FSB(multiplier of 6.5). Because they are unlocked, they can run at 1.26ghz@133FSB. That's a multiplier of 9.5. This mobo by default sets the multiplier @4. That's 533mhz, far below even the minimum for these chips, even at a multiplier of 6.5.

I have tried all 4 BIOS flashes available from the SOYO site, none of them has an option for setting the multiplier.

I've been OC'ing since '98, I started with a PII 266 which I OC'ed to 384mhz using Hoida's SoftFSB, I am not a noob, I've been OC'ing for a long time. The manual seems to say this mobo is good for OC'ing, but you'll notice, it does not say you can adjust the multiplier, which is far different from the FSB, which is the frequency adjustment it talks about.

These Tualatins are fully capable of running @1.8ghz, that's 189mhz FSB, multiplier of 9.5. Because I cannot get the multiplier up to 9.5, I can't run these puppies at their unlocked potential.

Big difference between the FSB, and the multiplier, but thanks for trying dude, much appreciated.

There is no multiplier adjustment. Its a BIOS autodetect issue. Contact Soyo, but I doubt they would release a BIOS to fix an overclocking issue on a discontinued product.

Dude, I know there is no multiplier adjustment in the BIOS, I know the updates to the BIOS have no adjustment, SOYO has never answered any of my emails about this board.

What I am asking, in my original post, is this: does anyone have any idea as to whether or not the pics I posted are the multiplier leads, and further, does anyone have an idea as to which I have to jump to get my multiplier to 9.5?

Sorry if I created any confusion here, but I thought my original post was very straight forward; I need help concerning increasing the multiplier to 9.5, and are those possibly the multiplier leads in the pics?

I am getting very frustrated here, although I am getting many answers, none of them relate to the question I asked: are those the multiplier leads, and which ones do I jump to get a 9.5 ratio?

***sigh***

I think I'll just buy a Mach Speed, it's limited to a 166mhz FSB, but at least it has an adjustment for the multiplier.

There are only two jumper packs (JP3 and JP4), each having only two pins, which would yield only four possible multiplier combinations. If it were a multiplier adjustment, it wouldn't make any sense to have so few combinations. My educated guess would be no, its not a multiplier jumper. Most likely, its a FSB adjustment circuit.

BTW, even an inexpensive KT600+VT8237 board with 2+GHz Athlon XP would be far superior to a Tualatin setup in performance and features. Or a cheap Socket 754 board with AMD Sempron. Buying another Socket 370 board may amount to throwing good money after bad.

Ummmm, wrong, 4 leads make for many combinations, not just four, do the math. My old DFI CA64 TN has 4 switches to adjust the multipliers, and there are a lot of combinations, probably 20, and that's just for that board, I'm sure there are more combinations one could make with 4 contact points, I'm just not in the mood to do the math myself right now.

A quick example: 1/2, 1/3, 1/4, 2/3, 2/4, 3/2, 3/4, 1/2/3, 1/2/4, 2/3/4...... the list goes on, it's not infinite, but there are a whole lot of possibilities.

 

[tcsenter]

JP3 ---- JP4

0 -------- 0
0 -------- 1
1 -------- 1
1 -------- 0

0 = on
1 = off

2 ^ 2 = 4. I think we're beginning to see where your many problems begin....

DFI CA64 TN has 4 switches to adjust the multipliers

Umm, since when is four less than two?

2 ^ 4 = 16

Questions?

Dude, I did not come here for your sarcasm, nor is it appreciated.

There is no need to act superior, especially when you are WRONG.

There are 4 contact points, just like the 4 switches on my DFI mobo.

So, before I take my leave of these forums, because a "lifer" has decided to attempt to make me look like a fool, here's just a few combinations, PAL......

1-2-3-4 off
1-2 on, 3-4 off
1-2-3 on, 4 off
1-2-3-4 on
1-4 on, 2-3 off
1-3 on, 2-4 off
2-3 on, 1-4 off

The list goes on, but you go ahead and think that you're superior to others, Einstein.

I'll just leave now, thanks for your input, obviously you don't want new members in these forums, your actions have just lost one, way to go. :disgust:

Two pins = one switch, genius.

 

[tcsenter]

Your DFI CA64-TN has EIGHT pins between four switches, not four pins between two switches as the Soyo does. Each switch has 2 positions (off/on).

According to the CA64-TN user manual, guess how many CPU Multiplier settings there are? Yup, exactly 16 (4x ~ 12x in .5x increments), as I predicted.
