I am having a hard time finding specs on the Sempron scoket A 3300. The biostar m7ncg 400 bios defaults it at 200. I set it back to 166 and when booting it reads 1833mhz. I really can't find any documentation that tells me if 1833 is correct. When I set it to 200 it boots up as Semprom 3300+. I believe that might be correct. Can Anyone help here? Thanks Bruce

3300 dont u mean 3000 the socket a semprons did'nt go above 3000 that and topped out at 2.0 ghz 512k cache and the fsb was 333
February 13, 2006 1:21:27 PM

Yes it is a Sempron socket A 3300+ Bought from tiger direct. When I leave the default value that the bios comes with " Front bus speed 200MHZ" It is very responsive and with no ill problems. I just can't find ant tables to verify that the default value that the biostal bios comes up with is correct. Bruce

i think your lying ok i cant find it on pricewatch nor tigerdirect.

I believe you, ive seen that chip before, The 3300 was supposed to run at 2.2ghz at 200mhz fsb. Its fine. Those semprons are really AThlon xp 3200+s repackaged with half l2 disabled. When AMD switched the name, some unsold XPs had to be "disposed of" so they just give them the name 3300. They are no longer produced so its a rather rare chip.

I don't know what the default specs are supposed to be but 1833Mhz would give you a ~166 Mhz FSB (11x166) @ DDR333. If the sucker boots at 200Mhz and is stable leave it at that! That would give you 2200Mhz @ DDR400.

You might be able to get some info from CPU-Z. I believe it reads the CPU designation and reports the proper equivalent no matter the speed (i.e., if it's a 3000+ with a 3000000Mhz FSB it would still be a 3000+).

thank you wellin i never thought amd did that with the old xp 3200(and now i know and knowing is half the battle really whats the other half beating the shit out of those commie bastards! thanks G.I. JOE go JOE!)

I see those items on Tiger Direct. They certainly seem to be a good deal on the surface. They would be a good deal if there was ever any hope of you actually receiving the rebates attached to them.

There is one thing constant about Tiger Direct: You absolutely, positively will NEVER receive ANY rebate advertised by them.

If you are shopping Tiger, you are getting ripped off.

Go to NewEgg or ZipZoomFly. Much better pricing, and they actually mail their rebates out!

"When I set it to 200 it boots up as Semprom 3300+."

Ergo, it is correct...uses 200 MHz as base clock freq...

Yes, the socket A Semprons are indeed merely XP's renamed with less cache...
February 13, 2006 10:40:13 PM

They are good deals. I have received my rebates all three. I called AMD and they did verify that these are indeed athlon cpu's. Renamed sempron.He told me that 200 fbs in the bios was right. I was amazed at the respond time in windows for a Sempron. Thanks Tiger. I got the M7NCG 400 mobo, 3300 sempron. heatsink and fan, case with 400 watt PS for 99.00 after rebates which I have received.

I bought this combo too. I bought PC3200 400MHz memory and forced the options on the motherboard to it but it was very flaky - freezing at different times. I was confused by the specs which some places says it supports up to 400MHz DDR memory but other places says 333MHz. On the DDR333 setting, it has not frozen once. In case you are wondering what a maximum temperature for your cpu is, the AMD site quotes 69 degrees C. Did your motherboard have a CD-in header? Mine did not. :cry: 
February 21, 2006 10:44:52 PM

Yes mine had a cd in header. You are right, when I had the fbs set to 200 in the setup It would reboot half way through formatting the D partition on my drive. It did this two times. When I set the fsb to 166 I had no such problems. It is a fairly fast system with the 3300 cpu. Nothing compared to my 3800 dual core Amd on the K8n nmeo4 plat. board by MSI. Bruce
February 22, 2006 4:54:23 PM

At 200Mhz base mine runs fine and the WarpSpeeder egg-thingy says the processor is runnnig at just under 2200Mhz - it was my forcing the memory to DDR400 that was the problem. I was just at the Biostar site (http://www.biostar-usa.com/mbdownloads.asp?model=M7NCG%...) and noticed they have a BIOS update NCG1221.BF4 - "Added support for Sempron 3300+ processor. Without Biostar splash screen." Anyone tried this?
February 23, 2006 1:35:45 AM

I did the bios flash and instead of the bios default at 200 when I open the bios up it was defaulted to 100fsb. Still I could not complete a format it would reboot half way through. Bruce
February 24, 2006 5:32:35 PM

I bought the same thing from TigerDirect.

At the beginning I had 512MB DDR333 which could only boost with 166MHZ to obtain 1.8Ghz. Then I bought 512MB DDR400 with 2.5CAS and still couldnt boost to 200MHZ to obtain a stable Sempro3300+ config. The OS just hang or wouldnt run the XP CD/format drive all the way.

Have someone opened a support help through Biostar? I will do that later today after work. I am sure it has the latest Bios but will find out later.

If someone can make it work with 200MHZ, please let me know how-to.

Thanks.
February 24, 2006 5:39:51 PM

I believe I flashed with the latest bios and did nothing to make the system more stable at 200 fsb. Bruce
February 24, 2006 7:13:52 PM

Your BIOS version number will come up with the starting screens. If it goes by too quick, delesect Quck Boot in the bios and restart. (I think there's an elegant key press that freezes the screen but can't remember what it is). The BIOS version I had (as shipped) had the most recent NGC1221 BF (or similar). I don't know what to tell you. At one point I trashed the BIOS and had to load the defaults - turn off - jumper the correct contacts - wait 15 sec - unjumper - restart (see the manual). I have one stick of 1 Gb 400Mhz DDR from Kingston in slot 1.
February 24, 2006 9:11:41 PM

I have checked it had the latest bios compare to www.biostar-usa.com. I have also reflashed with the one from that site just in case the one that came with mine is bad.. still no luck. The bios is NCG1221.BF4 with 12/21/2005 date.

Thing I tried today

FBS = 200, DDR=400.. just hang
FBS = 200, DDR=333.. It loads XP but will hang after loading notepad or calculator.
FBS 166, DDR=333, it works great but at 1.8Ghz :( 

I have submitted a form to biostar tech support but dont know when they will get back to me.

The 512MB PC3200 is from Buffalo a CAS 2.5

Tomorrow I am going to the place where I got the RAM and tryout with a Kingston 512MB PC3200 with a CAS 3.. and see if that will make a difference..

Tigerdirect sux in terms of getting any tech support.. they just referred me to Biostar :( 

Anyway, if I have any luck, will post in here. Thx.
February 24, 2006 10:52:58 PM

Keep me informed. Bruce
February 25, 2006 7:48:48 PM

I have tried with Kingston PC3200 CAS3:

FSB=200MHZ, DDR400 (wont boot at all)
FSB=200MHZ, DDR333 (Will boot but will restart intermittently shortly after a while)

I am using FX5200 rather the onboard Video.. Will try later taking out the AGP card and see if more stable or not.

I read somewhere that you need to have 2 stick of RAM to make it work.. not sure if that is true or not :( 

Anyone know what this sempron 3300+ socketA requires PC2700 (DDR333) or PC3200 (DDR400) ?

Please advice.
February 26, 2006 2:10:18 AM

I have removed the FX5200 better but crash somewhere.
The onboard nforce2 MX video sux..cant deal some of the kid's game. So tomorrow will have to plug the FX5200 card back to it. I will use the PC2700 or DDR333 and set the FSB=166MHZ.. so the total output will be 1.8Ghz rather 2.1Ghz...

I give up.. this is a waste of time with this board.. still waiting Biostar to get back to me about this issue.

Will see later on.

Oh by the way, this board not worth to have 2 sticks of RAM.. 1-512MB is good enough for a little kid PC.

Thanks.
February 26, 2006 12:30:36 PM

That is what I did. I quit wasting time and bumped it back to 166 and it seems to work fine. You won't to much difference between 1.8 and 2.1 that you can tell. The only thing that I did notice on 200fbs was it seemed to be to fast. When I first booted into windows it would seem to move before you told it to. Now that is scary. Bruce
February 26, 2006 12:55:18 PM

Yes 1.8Ghz and 2.1Ghz is not much or you wont be able to tell (200MHZ maybe a bit faster).

The principal in here is that sempron3300+ should work as advertised.. unless Tigerdirect and whatever this custom AMD cpu that is not supported by AMD is a fake one.

Well I will leave as is to run at 1.8Ghz and if I hear anything from Biostar (crossing finger)... will let you know.

But I will have to plug in the AGP video card back to the board.. so many kid's game that use rendering does not work with the onboard video.. also I have tried to set 128MB video onboard.. seems to work alright with everyday online browsing but not for 3d stuffs.

Stay tuned or unless someone out there have a clue :cry: 
March 2, 2006 10:15:13 PM

Bruce,
Download speedfan 4.28 and find out what temperature you have for the ACPI.. I think your temperature is very high.. Should be at 26-28Celsius.
Speedfan

I have changed my CPU heatsink/fan to replace the original one that came with the bundle:
Tigerdirect

So far I can use FSB=200 but only RAM by Spd in the Bios.. so at bootup time you will see Sempron3300+ but only DDR333.. even if you have PC3200 which is DDR400.

I sent another note to Biostar to inquire about this difference.. if no answer but still I am gaining extra 300Mhz at a stable stage.

The culprit was the heat. Another test you can do from the Bios PC Health Monitor, if you see the temperature of 48-52C.. that is too hot. I have seen mine with the old heatsink/fan gone all the way of 62C!

The reason why it works at FSB=166Mhz is only random because I have achieved high temperature of 55-58C when running at that speed which was stable for me and you.

Hope this helps you too.

My temp never got over 50 cel. That is not uncommon for amd. I have been running a pc with 1280 barton at 114 to 125 with no problems for years. That is with the stock fan from AMD. Bruce
March 3, 2006 11:32:40 AM

I'm wondering if these boards are quality "seconds". Your board won't run at top speed and my board does but is missing the CD-in header for music. BTW, I sent TigerDirect a note about the missing header and their (stock) reply was for me to send the original board back, once they put it back in stock they'll credit me and I can buy another!! I'm going to live headerless (and CD music-less) I think.
March 3, 2006 12:49:18 PM

Well,
Everyboard is built differently in terms of QA.. but the problem I had was closed to Bruce and was resolved by reducing heat.

I had it running last nite for 5 hours and temperature never went above 40Celsius.

It ran all the applications/games that I couldnt before when the temperature was high at 62Celsius.

I am still waiting a reply from Biostar to find out why any PC3200 RAM could not achieve DDR400 (Tried Ultra/Buffalo/Kingston/Corsair, all achieved when selecting By Spd from Bios up to DDR333).
March 3, 2006 1:02:43 PM

I'm not that educated in motherboard-speak but if you go to the info page on the board http://www.biostar-usa.com/mbdetails.asp?model=m7ncg+400 you'll see that it supports up to 400MHz front side bus processors but only up to DDR333 memory. Looks like you have to move up to the M7NCD (G->D) series to get DDR400 memory functionality.

Yes, it supports up to DDR333 only when the onboard video is used but can go up to DDR400 when the AGP is used. The Bios can see DDR400 but not very functional at this point.. Still waiting Biostar to get back to me.. so will see.. I am still happy if it cant go to DDR400 but was just curious if the board can function to its potential without overclocking as we speak. :wink:
March 3, 2006 6:13:36 PM

I believe if you run it at 166 fbs it will not have a problem with heat.I built this for a doctors office and the applications he will be running are not intensive. Bruce

Hello all,

I too have the same Sempron 3300 Package. I have been working on solving the mysteries of this processor for a year now, and I can tell you, the package is not what it seems.

The Sempron 3300 is literally an Athlon XP 3200 Barton with a changed CPUID. It has 512kb L2 (Not common for the Sempron Line), and a 400Mhz FSB. The reason for the 333Mhz memory is due to the fact that the motherboard has a 6:5 (FSB:Mem) Ratio. Therefore, 400:333 is the ratio for memory to FSB.

The processor has the full capability of an Athlon XP 3200 Barton, but the motherboard, on the otherhand, is a tad flaky.

If you want 400Mhz memory, buy an M7NCD 400 (Note the D). Or a VIA 8KRAI PRO (Bought one, was faulty though).

I hope this clears all up, and trust me, the Processor has all of the Specs of an XP 3200 Barton with FULL 512kb L2 On Die/Full Speed.

Cheers,

ZapperJet

As typical with allot of Tiger oem processors this one went bad. So I don't have to worry about how I can run it. Thanks for the good insight. Bruce
