Problem with getting Tekram i810 mobo to work with C2!!! - AWESOME NEW INFO, CHECK IT OUT!!!

[LukFilm]

Hey guys!
I bought one of the Tekram motherboards (S381-M+), but it does not want to work with my C2/633! When I put Celeron 400 PPGA in it, it boots just fine, but with C2 it's a no-go! What can I do? I know the board supports C2 and I flashed BIOS to the latest version and still nothing. Please help, I am getting desparate here...

it shouldn't work with a C2 anyhow, the i810 chip OFFICIALLY doesn't support it.

you got that board for 50 bucks in their site huh?

 

[hans007]

it says on their site that it supports up to celeron 800 but not fc-pga coppermines. Kinda like a bm6 i guess. Its supposed to work, if it doesnt ,c all them, and they'll send you another they have really good tech support.

 

[LukFilm]

Could my CPU be shot? I got a retail box from Onvia, but I guess these things do happen...

 

[rahvin]

The Cel-II is a FCPGA and the board doesn't support that voltage.

Try again rahvin

edit;
BTW link is here

 

[LukFilm]

Hmmm, I emailed Tekram and they said that it only supports Celerons 500 PPGA! What the heck? That's weird because their site says otherwise...

 

[rahvin]

Office boy,

I know I'm right.

 

[office boy]

Do you?
Might want to check some of these pictures

 

[andylawcc]

sure ravhin, you are so right, and there's a MTH in a i815 too.

 

[JackMDS]

Can some one please post the FSB speeds that are available on the this Tekram motherboard(S381-M+)????

<< it shouldn't work with a C2 anyhow, the i810 chip OFFICIALLY doesn't support it. >>


You'd better tell Intel then, because they officially state it does. However, I don't know about the Tekram board specifically.


One point though... even if the voltage regulator does go as low as 1.3, the website states that FC-PGA Coppermines do not work. Of interest as to why a 533A might work but a 633 might not is this little bit of info:

Intel® Celeron? Processor
Use of the boxed Intel® Celeron? processor on Older Flip-Chip Pin Grid Array (FC-PGA) motherboards

Integrators should use Intel® Celeron? processors up to 600 MHz maximum on older Intel® 810 chipset family motherboards. The reason for this is that the older boards implement a uniplane design where as flexible motherboards implement a split Vcc and Vtt planes. To run Intel Celeron processors greater than 600 MHz requires a split plane Flex-ATX board like the Intel® Desktop Board CA810e.

Please contact your motherboard manufacturer to determine if this processor is supported on your motherboard.


I don't know if this directly applies, but maybe it will help you clarify the issue. Also, it is of interest that the 533A uses a nice round number of 1.5 for voltage. The 633 uses 1.65 V. I know there are a couple of boards that get kind of confused when you ask for numbers which aren't multiples of 0.1 V, for whatever reason.

Regardless of whatever your pictures show other than a bunch of wires. That motherboard does not support FCPGA, there is more to supporting the voltage than supporting the voltage. The FCPGA changed the PINs that voltage applies too and the M+ sold in their clearance shop doesn't support the FCPGA (as can clearly be shown by the comments of their own tech support people). There is a version of the M+ that does support the FCPGA but it isn't the one sold in the clearance shop.

dipsh!t,

The MTH is integrated in the i815 bridge, ever since Intel focused on rambus, the Hub design they implimented has favored rambus and been retrofited with SDRAM later. Now there isn't a seperate MTH chip because they learned their lesson with the recall but it doesn't change the fact that every chipset since i810 has been focused to rambus with SDRAM stapled on later. (the orignal i810 supports rambus, the i810e was a later revision that stapled SDRAM on). I stand by my statement that every intel chipset since the BX was designed for Rambus and retrofited for SDRAM (giving bad performance) and that VIA is crap. (although still better than current intel offerings it doens't change the fact that deciding between two sets of crap means one is less crappy). And this has NOTHING to do with the thread so why don't you just shut up and go back to your corner.

 

[office boy]

This MB was purchased from Tekram's online (clearance) store,
Could you please explain these two comments to me?

• there is more to supporting the voltage than supporting the voltage
• Regardless of whatever your pictures show other than a bunch of wires

Neither statement really makes any sense to me, (could be your intellect is beyond my comprehension (or not ))

Try again MTH boy?.
I like Eug?s theory

 

[rahvin]

The motherboard must support the voltage on the correct pins. The FCPGA switched 6 of the pins around. If you don't understand that, read Anands review from when the FCPGA chips first came out. You can easily support the voltage requirement on any of the i810 boards and not support that voltage on the correct pins thus making the motherboard incompatible with FCPGA. That's why they call it FCPGA and not PPGA like the orginals, to differentiate them smarty pants. And if you had BOTHERED to look at the webpage you would have seen this:

As far as the second statement, I was pointing out that your linked pictures do not show anything of any value.

Store link

&quot;S381-M+ sold online is version 1.01 which does NOT support Pentium® III FC-PGA CPUs&quot;

See if people actually bothered to look at the blooody store web page we wouldn't be having this discussion now would we.

 

[andylawcc]

well ravhin if you weren't bloody born and then become bloody stupid, there would be peace in humanity.

 

[office boy]

Hello are you stupid or just blind, did you not see my pictures? Yes they are of a C2 533a running on a M+ and a ML. Both motherboards purchased from the Tekram store that don't support P3's.
I don't think you have any idea what your talking about with the pin voltage, because if you were right I would have either fried my Celeron2, or it would not have booted

Lets also look at this shall we?
<<&quot;S381-M+ also the M/ML sold online is version 1.01 which does NOT support Pentium® III FC-PGA CPUs&quot;>>
Ever think that the problem could be something else? Besides voltage? I'm pretty sure that <<CPU Speed Switching Voltage Regulator: 1.3V~3.5V VRM 8.4>> blows your theory out of the water.

Edit to add quote like things

<< As far as the second statement, I was pointing out that your linked pictures do not show anything of any value. >>


Just saw this....
and I guess a dipshi[/b]t like you would think that a fc-pga chip running WinNT on a M+ wouldn't mean anything... crap get lost would you lamer :|

 

[Eug]

OK everyone calm down...

rahvin,

According to the many reports out there, one can run a FC-PGA Celeron on a PPGA slocket or motherboard if the motherboard BIOS and voltage regulator (etc.) support the processor. You cannot run a FC-PGA PIII with the same setup however. It would appear that the modified pins for FC-PGA are not used on the Celery FC-PGA chips. In fact, I don't even have my MSI MS-6905 Master slocket set to &quot;Coppermine 256K&quot; with my Celemine. It's set for &quot;Single processor&quot; at the moment, which supposedly is for PPGA chips (although it isn't clear on the Microstar website).

 

[JackMDS]

When you get tired of cursing, and name calling.

Can some one please post the FSB speeds that are available on the Tekram motherboard (S381-M+)????

 

[office boy]

I'll need another hour JackMDS

j/k No I'll check when I get home...

Edit (UPDATE) I found a link where someone said that the board has FSB speeds up to 140Mhz....

 

[LukFilm]

Alright, I think that EUG is the person who is RIGHT. Because if I look at Tekram's websiteRIGHT HERE it says that it supports Celeron's II, though they DO NOT list anything over 600MHz. This leads me to believe that the motherboard DOES support C2's; however, only up to 600MHz and the information that Eug posted further confirms that. So, now I just need C2/600, so I can REALLY make sure that that's what the problem is. Anyway, thanks for the help everyone, now I know what to do the next time I get this motherboard...

[LukFilm]

office boy,

do you remember the discussion we have had in my Hot Deals thread regarding Tekram S381-ML motherboard and whether or not it supports Coppermines PIIIs??? Well, from what Eug said it seems that it REALLY does not support PIIIs because of the problem outlined in the article. Well, it would be too good of a deal if it did. Anyway, I am glad that it works up to 600MHz, now I know what to purchase next time...

[LukFilm]

Dudes!!! CHECK THIS OUT! I made Tekram change the information on their website! Now it says it only supports Celerons PPGA and not FC-PGA! Can you say - LukFilm rules?!?!

Actually, I will email them one more time saying that it DOES support C2's, but only up to 600MHz. We'll see what they will say. But that's so cool that I made a company change their website

 

[office boy]

Very cool
And yeah I do remember that thread. I wish Eug was there back then.
