:D
stevil got his kt333 to 210fsb i think
since kt333s are beefed up kt266a boards with a 1/5 divider i'll just post my kt266a record as well :D
my 4ss-rock kt266a board does 190fsb 100% stable with a 66mhz ide card and a g4mx, not bad for a 1/4 divider :D. crappy rails atm, will mod my second psu and see how high i can get with it.
230 with an epox 8k3a rev 1.0
Screens Screens m8 ;)Quote:

whats the secret to getting 8k3a's up so high, i hit a wall at 205 for stability and 211 max bench ever but i hear the 3.3v line really needs to be high to get the most? As mines at 3.25 i guess that might be why im still down low 200s

Nice Results @ All !
@stergiopilus
Northbridge Cooling ?!
@ All
Plz post ur Northbridge Cooling !
Im only @ stock passiv Cooler.
Ur PCI and VGA Cards are very importent !Quote:

With an Ati, its very hard to hit > 210.
Hdd too.
All ur Parts must be perfect to hit such a FSB.
i removed the nb cooler as the nb was pretty cool even after some hours of priming.
does anybody know how to raise the chipset voltage on a kt266a board? cant find anything...
My Northbridgecooler is very hot !
I think 50 - 70 °C !! (just felt by hand)
Maybe i should buy an Watercooler for my Northbride. ;)
maybe the epox showed higher memory bandwidth but was slower in 3d?
But why it should ?Quote:

My best Result on 3DMark. Never tested with higher FSB.
http://www.zup-clan.de/Files/3d.jpg
Couldn't agree more!!
I still run an Abit KR7A-133, set to 174 Mhz FSB for daily use (43.5 Mhz PCI), and a KX7-333 set at 185 Mhz FSB for daily use (37 Mhz PCI). It's fun to crank either of these boards over 200 Mhz FSB and show off the two year old hardware. I regularly embarrass some of the brand new stuff. The Ultra-Agressive timings offered by these boards meant that FSB Mhz to FSB Mhz, they destroyed most any other brand. The fact that they show no IDE corruption even at over 45 Mhz PCI speeds is a testament to how good these boards are.
I have done stability tests on my KR7A-133 at 50 Mhz PCI, and after 24 hour of Prime95, had no errors.
All this, and air cooled!
The 8k3a's had "Fast Command Decode" disabled over 166mhz FSB... Abit's did not. This is the majority of the performance difference.Quote:

The performance difference was eliminated with 10-15 extra mhz FSB, not 30-40... With that said... The kx7-333r were definitely the best performers overall.
BTW, my 8k3a ran at 230mhz fsb (On a cool morning ;) ) .
I've got a KX7-333 and a KD7-333 and both have hit over 200 fsb with Corsair XMS pc3500, using the 1/5 divider. :cool:
i've gotten an 8k5a3+ up to 185FSB...
Abit kd7-e, memory-limited at the time
I dont think so !Quote:

It was an Bios Prob, and with the newer Bioses they fixed
that "Bug".
With old Bios u had on Memory Bandwith Benchmark @ 200 MHz
2500 - 2600 but with the newer ones ~ 3000 Points.
Someone have still an KX333 in operation, and want to make
some Benches @ 200 MHz and 2-2-5-2 2T ? (same Multi)
I want to know it :D
Actually, the older 8k3a BIOS had it enabled, and the performance was great... but no one could go over 185-190mhz FSB... the 8k3a2815 bios (from August 15th 2002) was the last one with FCD enabled over 166mhz ... ALL BIOS after that one have FCD disabled over 166mhz.Quote:

The newer BIOS's ALL had FCD disabled over 166mhz. It was not a bug, it was disabled purpously to achieve the highest possible FSB. Eventually they got the memory scores up there with the competition, but overall performance was never as good "clock per clock" as mobo's with FCD enabled. As I said above an extra 10-15 mhz FSB would even out the speed difference.
For me... I got up to 185mhz FSB with older FCD enabled bios(Which equals about 200mhz FSB w/ disabled) However, with newer FCD disabled bios, I hit 230mhz... much better scores :D
Which Bios do u use ?
I hope we will find someone with an KX333 ;)

Ps: no mods on the mobo
When i did those screenshots I was just using a little heatsink (a bit bigger than the stock one) with a 40mm fan. Afterwards i chucked the watercooling on it and i couldn't get any higher.Quote:

Ur PCI and VGA Cards are very importent !
With an Ati, its very hard to hit > 210.
Hdd too.
All ur Parts must be perfect to hit such a FSB.
As for video card, i was using an Radeon 8500 which can handle high AGP busses very well. Later on i used the same 8500 in an NF2 board and ran the AGP bus at 95MHz or 100MHz (can't remember which one, but it was the highest the bios would allow) and it ran perfectly with everything i threw at it (3dmark etc). Later on i tested a Radeon 9800pro in the 8K3A and i couldn't get over 218MHz FSB with it, so it is only the newer ATI's that have problems with high AGP speeds. The older ones seem fine with it.
As for PCI cards, i didn't use any at all. The only time i need a PCI card is when i go to LAN's, and then i just chuck that card in.
As for Hard drive, i used a 40GB 7200rpm Seagate Barracuda IV. It is still running perfectly till this day, so it must also like high PCI speeds.
WPCREDIT was nice for the Epox 8K3A+.
Too bad my board didnt like going past 210... if I had known the 3.3v mod around then you may have seen me in the 225-240 range (yes, some did go 240+ with 3.3v mods). :D
with 8k3a+......3,3v @3.4v
http://ztop.altervista.org/238.jpg
did any of you mod the chipset voltage? anybody?
The chipset runs straight off the 3.3.
u sure? ive read about it and the abit kt266a board was the only one with a pin to raise the chipset voltage. default was 3.15 iirc.
Could be wrong, but thats what i've seen stated before..
maybe its bound to the 3.3v rail so when i raise it i raise the chipset voltage?... i couldnt boot my kt266a board with my modded psu (14v 5.8v 3.7v) maybe because ´there was a chipset overvolt protection... damn those overvolt protections!!!! :upset:
whats the idear of limiting the a7n8x to 1.85vcore and then build in an extra overvolt protection that kicks in at 2.15v if its not just to pi55 off ocers... :\
lol
Wheres my WCPUID 225mhz fsb shot on my KR7A... :|
Damn im a idiot i erased that from orb also :\
wow crazy high fsbs. lucky guys too. I had an asus kt266a that did only 150fsb then an abit kt400 that did 190 max, wasnt even prime95 stable. could never get fast cpu decode enabled or it wouldnt even post :( how many marks was that worth anyway? I seem to have bad luck with high fsb, my nf7-s only does like 222fsb stable, 229 semistable and its a revision 2.0 im gonna try the L12 mod for 235+ fsb
Lost my screenies in my last format....... I was able to take my 8K3A to 205 at the highest, 200 if I wanted it to be stable.
Yeah i had a 8k3a+.... pos, did only 202mhz fsb...
does pci bite?
Yeah I've had the same experience with my abit kt266a vlad. I can get up to 168fsb 100% stable, with 170~ being pretty close with 2.85v, but I need to mod my psu as its undervolting a little, and try upping my vdimm to 3v or so as well as better nb cooling, see where she goes :D
Hmm... i pumped 3.8V through my KR7...
Yeah, I would assume that would have had to do with the chipset and agp voltage (which are both tied to vdimm). I would be worried about going above 3.2v or so because of so many people burning out their agp controllers doing that back in the day on kg7s, kr7as and kx7s. berkut, you need to get aim or something, or tell me where you are on IRC so we can talk more :D I miss the crazy phase change convos man
so the agp voltage is bound to vdimm as well? whats the max vdimm i should try then? i will be using a g4mx wich can take a lot of vagp, but i dont want to kill it. this is the miracle g4mx from gainward that does 400(!) core 700 memory absolutely stock.
IIRC, the Vagp and Vdimm mods were different on the VIA boards. Didn't MrIcee discuss the care in which the Vagp needed to be adjusted in order NOT to kill the board in the kx-7 thread(s) on these forums back in 2003, maybe 2002?
vagp and agp controller voltage are different, correct? I believe higher vdimm raises the controller voltage, not the actual vagp (which there is a mod for afaik), in which case it wouldnt affect the card at all, just burn out the mobo, or maybe just the agp slot. I think its all in MrIcee's kg7/kx7/kr7a vmod thread, could be wrong though.
With the agp controller being part of the northbridge, would agp controller voltage (for lack of a better name) be the same as the chipset voltage? Seems likely right?
As for how much is too much, I think MrIcee said 3.2-3.3vdimm was the safe limit.
Hi
If i rise my Vdimm on my 8K3A+ to 3,2 V the Vchip. and Vagp
will rise too ?
Did I understand it correctly ?
@ Nice Results at All !
nope, if you rise vdimm the agp controller voltage rises, vagp remains at the same level.
so 3.3vdimm is still ok without modding vagp? or 3.3v vdimm can only be obtained with a vagp mod or the agp slot/agp controller will burn out?
saaya: I believe 3.2-3.3v was the safe max, without any other modding. I'm considering doing a vdimm mod to my kr7a and trying about 3v to see if my max fsb goes up any. I feel bad about giving this BH5 so much more than it needs, but its not like a little voltage will hurt it or anything ;x
GravdiggA: I dont know anything about the 8k3a+ but if it uses the same setup for vdimm/vchip then yes. play with it and see what happens :P
when i had a kt333 the highest fsb i could get was 185mhz because of my hardrive corrupting! what hardrives are you guys running that will run insane pci speeds 24/7?!?! cant these high pci speeds kill dvd and cdrw drives as well?
im using a ibm deathstar 20gb. fine up to 180fsb... i just bought a ide card wich is supposed to run at 66mhz pci speed, will check that later.
untweaked yes you are rightQuote:

but not my 8k3a
only a tweaked kx7 could match it clock for clock
its like my 8rda stock , it doesnt match nf7 , but wpcredit tweaked :) abit bios kick ass thats for sure always have alway will
8k3a was a great mobo couldnt go as far as the 8rda didnt have agp/pci lock and not get higher performance in benchs
but via chipsets feel more responsive , lol
I have a KT333 sat at home for a friends rig, with an AthlonXP 1800+, the tasty stepping, he doesn't want to overclock, psssh, but I'm insisting on it, am I going to be able to get this thing up to, say 2GHz?
what stepping?
Had have an Quantum Fireball AS ; Samsung P80 ; Exelstor/IBMQuote:

40 Gb, and in sec. Sys. with an Albatron KT333 an IBM 15 Gb
and an Fujitsu 8,4 GB, and all work fine with 200 MHz +.
But Attention, the Raidcontroller wont work over 200 MHz.
(that cost me a lot of time to find it out ;) )
Only the Gforce 4 Ti from Leadtek on sec. Sys. cant get
higher then 205 MHz without Artifacts :mad:
Btw. , is there none out there with an working KX7 :D
Can't remember the stepping on the CPU, bt it's the ones that had the same stepping as the sweet 1700+'s, had it to 2.3GHz on crappy air myself, so I know the CPU can handle it, and at stock volts, I'm just not sure if the motherboard can manage.
I was pushing 211 for the top on my kx7, but that was hardly stable, i think i only ever ran 1 full 3dmark run at that speed.
My radeon9700pro wouldn't take it so i used a ti4200 and my hard drive was in pio4 or it would corrupt. It was generic pc3200 at nearly 3.4 volts, modded and at super-slack timings.
I got a little happy trying to push the ram farther and the chips on one side of the stick cracked. It still ran as a 128mb stick, but i just tossed it. Those were the days.
Had my kx7 as high as 218 FSB, but the AGP tearing was so bad Windows was unusable and BIOS settings had to be made from memory, the BIOS setup screens were completely scrambled.
Ti4200 at the time.
wow, the highest I achieved so far was 192Mhz fsb with corsair pc3500xms on an Epox 8k5a2 (typing on that rig now)Quote:

Unfortunately I'm only running 170 now (giving me about 2.2Ghz cpu speed)
The strange thing is, if i plug in my corsair or a friends geil pc 3500, the computer crashes after 2 or 3 days uptime :s
I get a higher stock score with 177 fsb, turbo, 2252 1t queue depth 4 burst length 8 2035 Mhz than at 186 2046 mhz same timings. 8K3AE. I know it's different, but not so different from 8K3A/+ boards... I used BIOS files for 8K3A/+ boards when I couldn't find updates for the E model, in Autumn of 2002, though contemporary wisdom is that they won't work. Currently using latest correct BIOS.Quote:

Maybe I'll try wpcredit and see what I can do with it.
I am sure the fast command decode comment from an earlier post is correct, but I suspect there are yet other latencies/settings involved as one goes yet higher in FSB.
Ok, now i found the old Thread on www.planet3dnow.de .
If someone can read german here is the Link !
Its from summer '02. Here some Facts from there :
My 8K3A with old Bios :
12x133 : 2049/1966
10x165 : 2548/2407
10x166 : 2479/2291
10x167 : 2492/2306
9x195 2-2-5-2-1T : ~2770/2550
An KX7 @ 190 FSB :
2876/2666 MB 2,5-2-5-2 1T
Ok, 8K3A sucks ..
Offizial Bios Update 25.08.02 8K3A+ :
sisoft memory benchmark mit 195FSB 2-2-5-2-1T :
2996 / 2780
Ergo the CPU FAST COMMAND is enabled !
I swear the 8K3A isnt slower then the KX7 !
We need someone with this Mobo !!!
The Problem was that the Epox with old Bios disable
the Fast Command Rate over 165 MHz FSB but thats past ;)
I sold mine 8-/
In a week, my vacation starts, so I'll have a week to test all rigs in the house ;)
Nice !Quote:

Till then :D
I bought that KT333 board to be in my first pc ever, but unfortunately I had to sell the whole thing after a couple of weeks (arguement with parents)
But I was fortunate enough to be able to sell it to my granddad, and I have to say, it's a good machine, and it's way more stable then my own nf2 rig which crashes on a regular basis (I'm off to install windows again, because I tried to add a HD and I can't boot anymore :()
Edit, GravediggA, just read your sig, does your corsair really needs that many volts? That's like stock speed for that stick of ram? :confused:
Dood, its not enabled any longer... The 08/15/02 was the official BIOS, 08/25/02 may have been a german release of that , because the next BIOS was the 08/29/02 beta , anyhow they are both OLD bios's ... There were several releases after that, and any BIOS after that has it disabled. the most widely used is the 04/09/03 bios... It was great, but FCD was disabled. The Very latest is 9/16/03 (the only change from 04/09/03 is added CPU support for Applebred )Quote:

I DO still have my motherboard in my 2nd PC... Epox has gone through great lengths to get the memory scores up higher, and it has worked...but FCD is NOT enabled over 166mhz. Memory bandwidth is only one test, it does not always indicate true performance. I spent years with this board, hanging out on Epox's forum with thier support rep, and his manager at AOA forums. I have tried every BIOS, I have even used WPcdredit to show what each value is set at, and FCD is not enabled.
Its still a great board. Absolutly one of the best OC'ing motherboards of all time.
Ok Ok :rolleyes:
But i want Benches !
I have an modded Bios from en freind , i think its was 2912,
but cant see it on Bootscreen.
Its only precaution ;)Quote:

done with a epox 8k5a3+, with original nb heatsink, and a tbred 2100+, i was using ocz el 3700 ram
http://bond.home.sapo.pt/Resize%20of%20fsb%40235.JPG
Not a kt333, but a kt266a.. close enough? Abit KR7A with slack timings (which is why the sandra score sucks).
It seems like 195 is the highest I ever got my fsb up (epox 8k5a2)
this was with corsair pc3500 xms C2 (one 256mb bh-5 stick)
Unfortunately, I only seem to have a wcpuid screenshot (it was far from stable anyway...)
I also seem to have gotten my 2100+ cpu as high as 2313Mhz
the highest multiplier I can select is 13, so the fsb limits me...
Think I once benched at 225 or 230Mhz (not quite sure though) on the Epox 8k5a2+, but that's more than 1 year ago.
Board is still is my son's rig. Will try to test it again tomorrow or so.
I recall that you said that on Born2oc too some time ago, I was pretty amazed by those numbers, have you done any mods?

Just screenstable ;)

so whats the board? someone find out, I want one!! :D
Hm, normally there is no modded bios which can help u reach 250MHz FSB 1M on a KT333 without any special modding, or maybe some handpicked hardware, that can run 50MHz PCI! ;)Quote:
