Abit KG7 Mobo - How far for an o/c newbie???

Assimilator1 — Thu, 27 Feb 2003 19:20:42 GMT

lol ,don't blame you ,the 1st 4-6 attempts are a PITA!

Adrainhants
Fitting DDR333 to your mbrd isn't a problem ,but you are very likely to have problems running your mbrd to 166MHz FSB.

Your PCI bus would be running at 41.5MHz!, and you would run a VERY high risk of corrupting data on your HDD ,that's assuming that none of your PCI cards stop working at that speed (not permanent).
Also your AGP bus would be running at 83MHz (instead of 66MHz) ,whilst most AGP cards would probably be ok at that it would still be another variable.
Another problem that could occur is that unless AMD produce 266MHz FSB Bartons their would be no bios support for them.Yet another variable.
I'm not saying a Barton wont work on that mbrd but the odds are against you!.

Inccidently an old rig I had upto about 4yrs ago had a similar problem.
It was an old S7 Asus TX chipset & officially only supported upto 66MHz FSB though it had 75 & 83MHz settings.When I plugged a K6-2 350 in it (which is supposed to be 3.5x100) I experimented with 75 & 83MHz FSB (4.5x & 5x multiplier),turned out everthing ran fine at 83MHz FSB.
Had I known at the time the risk I was taking I probably wouldn't of tried it .At 83MHz FSB the PCI/IDE was at 41.5MHz!.It worked like that for about 4-5 mths before I sold it.

Your best bet would be to buy an XP2100 (Tbred B core version,assuming thats supported) ,and raise the FSB to around 150-155MHz & then overclock the hell out of it.
Your current RAM might be able to do that (my PC2100 runs at 152MHz CAS2-2-2-6 ) or you could buy some DDR333.

Btw there's also a good chance that your 1.13 Tbird could run at around 1.4GHz .
Why not try overclocking that 1st?

If you want to find out just your RAMs max speed ,unlock your cpu (Tbirds are easy) ,set the lowest multiplier possible & then raise your FSB until it crashes (I wouldn't exceed 155MHz FSB though).
Bear in mind that even at 38MHz PCI bus HDD data could still be corrupted (though thats rare at that speed),ghost your HDD 1st to be safe

The same technique can be used to turn athlon XPs into MPs, I think it is the right hand L5 bridge you have to fix. I know this is not strictly what I originally posted about, but has anyone managed to o.c. a dual athlon set-up?

lol ,no!

Unlocking the XP Palminos is a PITA ,it involves filling in near microscopic pits on the cpu surface with an insulator & then joining some very small pairs of gold dots together with silver conductive paint.

Read this guide for a detailed explanation
http://www.tomshardware.com/howto/20011112/

One thing ,do NOT use superglue as he says ,I've discovered to my cost how difficult it is to remove if you mess up!.Instead use a Silicon sealant
Btw you don't need a specialist kit to do it ,here's what you need

Mini pot of Silver conductive paint (from a Heated rear window repair kit from a Motor factors)about £8
Small tube of Silicon Sealant (again can be had from a Motor factors)
One sharp pencil (to use as a brush,pin doesnt work)
One magnifying glass
One pin (to GENTLY scrap off any excess paint)
A steady hand
A bright overhead light casting no shadows on the cpu
Some IPA,meths or other solvent to clean off cpu surface

256mb ddr pc2100 ram
ati radion 64mb ddr+tv out graphics card with fan
56k modem
usb pci card
usb2 sockets
128 bit cound card
52x cd rom
32x cdrd
17" monitor
rf mouse
normal keyboard
450w psu with two fans
+one fan in system case

System temp up to 35c

cpu chip upto 55c temp

multipler set @- 11.5
fsb 148
Voltages uped a little as well

just need to get the multipler unlocked now but not sure how to do it, was told you need an unlocking kit that i think is a piece of software right ?

The KT333 chipset certainly isn't bad but the new Nforce2 is certainly better:)

The limtations with AMD760 & KT266/266a usually ends up being the PCI/AGP speeds ,as there is no 1/5 divider for the PCI on these chipsets.

I've also got Cruicial PC2100 CL2.5 (not ns ) ,its running at 152MHz at CAS 2-2-2-6 on my KT266a mbrd

Increasing the precharge control (think thats what its called!) from 5 to 6 allowed me to increase FSB from 145 to 152MHz.
Also my RAM voltage is at 2.65v (default for Asus A7V266-E!)

my kg7 raid makes it to 148fsb fine and stable with crucial ram 2.5cl set to 2cl and an athlon 1ghz, elsa gf2mx and sonic fury sound, but it will not post at all with 149fsb. However with a cheapy soundcard and an athlon 1600xp the unit will not boot at over 142 fsb (but it will post) but I have not the time or inclination to find out the culprit :-(

Keeping you posted now!! I have bumped up my FSB to 142 (any further and it has read/write errors on load up , even with the info list someone posted! But with that and the increase in my GPU clock to 265Mhz, and my Graphics Mem clock to 481Mhz, my 3DMark2001SE score has gone from :

http://service.futuremark.com/compare?2k1=5768644

to :

http://service.futuremark.com/compare?2k1=5773301

So a nice improvement there! I also removed 256Mb of memory, after finding out that some of my PC`s instability problems might be stemming from the fact that one stick of 256 has a 2ns Latency, and the other has a 2.5ns Latency...so the 2.5 had to go!!!
Anyway, to work I go, [Cry]

Right, firstly, My KG7-RAID is running an Athlon XP2000+, and will take up to a 2400+ with the right BIOS update. XP266+`s are not supported, sorry. Secondly, I`ve sorted my IE crashing problem, with PCmedik, and I can see it fine now, thanks for the offer, Adrianhants, it`s much appreciated. Now to see how to overclock my new 2000+, he he ....

I think Nvidia are AMD in disguise!

'Apparently' Nvidia have started releasing the chips for mainstream production, so we could expect boards to emerge soon after October

i don't think that AMD 761 will support 166Mhz FSB and will probably get no higher than 150Mhz FSB - and thats probably with some extreme voltage & divider tweaking and possibly extra cooling.

From what i gather the 333FSB Athlons are generally disappointing with Via Chipsets. AMD have yet to release a chipset for this FSB (i think!).
The only chipset to really take hold of the new Athlon and squeeze out more power are Nvidias Nforce2 - which showed 10-30% improvment over the same 333Mhz CPU in different boards!!

Read The Flippin' Manual (the intro anyway), it's definitely an AMD-761/VIA VT82C686B combo as it's a fairly early DDR RAM board. My apologies for this outburst of industrial archeology...

This one's a bit before KT333, 266A or 266! It's got a hybrid AMD/VIA chipset. More research needed...

If you got KT333 chipset onwards then you should be ok with 333Mhz - dont think the KT266(A) will support it.

Most boards are meant to be overclock friendly, but to be successful you need to following:-

Good PSU - 350W+ is best
Good range of mobo FSB dividers for PCI/AGP, etc - so that things can be kept in sync when FSB increase. IF not then one of these could stop you.
Good range of volatges for AGP/Memory, etc - if they can be set separately then you are in business
Possibly extra cooling for memory/CPU - fins for memory and/or air vents in case for CPU
Good CPU cooler

To find out how well your board can o/c unplug all unnecessary devices and try upping the FSB in 1Mhz increments - most boards with KT266(A) could go no higher than 150MHZ

Sorry if this is a bit of a repetition of the thread below. My year old KG7 is running fine at the moment with a 1.13 GHz Athlon and 512Mb of PC2100 DDR RAM, all on standard settings. However, I will probably want to do an upgrade a bit further down the road to get the most out of the existing kit, and as the KG7 was/is supposed to be an o/c friendly motherboard, could it actually be persuaded to run a stable 166 FSB for a Barton core Athlon? Likewise, is there any way that this board could be tricked into running 333 instead of 266 DDR RAM?

No urgency yet, but if it protects my investment(!) for a bit longer I'd be interested...
