VIA K8T800 socket 939 : what is maximum FSB you ever got?
My friend(ianho@lowyat.net) manage to do 310MHz FSB on his k8t800 board... anybody did this far before?

Is it a new WR for K8T800 chipset FSB ? never seen anybody go this far before....

Spec:
-------
AMD64 3000+(Venice) @2.8Ghz,
TT Silent Tower HSF with UFO Twin Blade fan,
Abit AV8 3rd Eye mobo,
2X512 Kingston KVR RAM,
Leadtek 6600GT,
Vantec Fancard,
80Gb WD HDD,
480W Enermax Coolergiant Red,
Custom Case with 4 Cooler Master fans.

CPU-Z Verified:
310MHz

i dont have any screenies from my ABIT AV8 times, but i did 320 without probs. i think quit a lot of people have gotten there with AV8.

[drunkenmaster]

is that board k8t800 or the pro version? the locks were iffy on the chipset to say the least but afaik works 100% of the time with any divider locked in, just 1:1 the lock wouldn't always work. so yes, high fsb is piss easy on that chipset in anything but 1:1. from what i recall it was mainly the a8v asus boards that had some major issues hitting such high fsb, they most often wouldn't break 270mhz.

its more likely to be the unofficial record as no one really uses the chipset for high overclocking and haven't for ages. tis a really nice chipset but just not as easy to hit as good speeds 1:1 and they also have a lack of well made boards with the needed voltage options.

Varzmaster posted this a while back on a romanian forum:

Abit AV8 / Winchester 3000+ @ 5X340 / 256MB Corsair 3200XL @ 340Mhz 3-4-4-10



And with 4X multi (memory running at only 275Mhz, even if CPU-Z is showing 344):

my bad...
anyway nice FSB there Micutzu
congrats

and thanks for the info guys....

sorry ... it is VIA k8t800 pro
AV8 rev1.1

and it is on Bios 20...

Bios setting:
External clock- 310/66/33
AGP ratio- Fixed(66mhz)
CPU V- 1.6
AGP V- 1.65
DDR V- 2.8
NB V- 1.6
SB V- 2.55
HT V- 1.25
DRAM Clock- DDR 266
LDT bus fequency-FSB X 3
RAM settings- 3,4,4,8

320 on the Abit Av8 1.1 that i had. no Screenys though and 3d was hella unstable on that thing :s

[calcal]

dang those av8 kicka**

can they run dual channel?

[TMM]

Yep. though mine couldn't run 3dmark, or rather anything 3d at over 255htt~ with 66mhz AGP lock
iirc it was a memory / lock problem
running mem @ 266, or AGP lock @ 74mhz fixed the problem... totally messed up board imho.

[drunkenmaster]

yeah, 3d stable was very difficult iirc, that seems to often be the case with via chipsets, or maybe just on ath 64 stuff from them, not sure, i can hit hella fsb's with a divider, but tbh it doesn't help performance in the slighest, running 275 1:1 or at a guess 340/275 with a divider, given same mem speed same bandwidth will be achieved and almost identical performance. but above 270 or so 3d stable on my a8v, av8, and i think one of the gigabyte boards was not really possible.

[Stuperman]

255~ with my Asus A8V deluxe, that's what i get for going 939 really early (july/04)

[sl1m shady]

A friend did 320 with a winchester 3000+ and patriot xbl asynch on an abit av8 3rd eye

[pasatoiutd]

Congratulations, Micutzu. It seems that the air from Ploiesti can really make some miracles.

[Micutzu]

Thanks guys, but i've said in my post, those are Varzmaster's screenshots, not mine.

[gergo]

Nice fsbs

When i set the cpu to 300*8=2400mhz, then the cpu is stable( i tested with Prime95) but the 3d doesn't work . I use mem divider 266, becouse my rams don't go together upper than 430mhz.
Why not work the 3d?

[AH^DK]

313x9 on A8V, 308 rock stable.

[Zangetsu]

running mem @ 266, or AGP lock @ 74mhz fixed the problem... totally messed up board imho.

So what you mean is just put mem on a divider and agp lock to 74MHz and its all 3d stable for 24/7 use?

Just curious cause mine is not 3d stable as well and if this solves the probs then I'm gona try it.

[kj™]

anyone got max fsb for an asus a8v deluxe rev 2.xx??
does it exceed 300?

BIOS = 300, Use Clock Gen to push further.

[kj™]

BIOS = 300, Use Clock Gen to push further.

i meant that wat max fsb that this board asus a8v 2.xx is averagely stable?
im sorry..

Here's my latest attempt at highest HTT for my AV8. 345HTT. Screenie attached. Also CPUz verified at

yeah... this is the man ....

to XtremeSystems!!!!


ianho... is it 3d stable at those super high FSB...
most people said anything higher than 260MHz will crash 3d application away...

is it posible to play games or 3dmark benching at 300MHz HTT ?

Well, I just got my water cooling setup n running fine now. Finally got down to Priming n 3DM05 benchies. I'm still watching my temps with the new set up so I'm still being conservative with the OC. Right now am at 290X9. 3DM05 without a problem. I've been benching it like mad all day trying to get to the top of Lowyat 8 pipelines rankings. Now at #5 haha. So yeah, I can say 3D is rock solid at 290X9. B4 this I cudn't even run 3DM05 when I had the AGP fixed at 66. Then I heard sum1 say try 74. So I tried it n it works a charm. Been Priming 290X9 for the past 5 hours. If all goes well, will Prime n bench 300X9 2moro. BTW thanks 4 the welcome

[babyelf]

lol u made it..

show us more

[ianho_]

lol u made it..

show us more

Well, this just my 1st session of Prime n 3DM05 since getting my Venice 3000+ n AV8 combo. Pretty decent results I wud say. Gonna push for more soon. But here's the screenies of 290X9.





N here's the ORB link showing the 290X9 setting passing the 3DM05 with flying colors. Hahaha. Who dares to say the AV8 can't do 3D above 260HTT now?
