Venice 3000+ Tweaks for Max Screen

[KoNiaK]

This the best max screen I got from my venice.



http://valid.x86-secret.com/show_oc?id=63613


I'm sure it can go higher, but I need to tweak my rig.

I have the same result for 1.77v, 1.80v and 1.84v. The chip can run from -26°C to -21°C it would always max out at 3500MHz. Weird isn't it? Something holding me back!

Can some one advise a bios and what to disable in it?

I'm runing 310p with a single 256MB stick 2T and use a PCI display card.
I tried to disable everything wich isn't useful, exept SATA, is it known to have an influence?


Thanks for your help guys



UPDATE

Using PATA drive gived me a far better score, but switching bios wouldn't help at all

This time I saw an improvment going from 1.77v, 1.80v and then 1.84v but none at 1.9v I thought temperature might be holding me back. I think die was around -22C for 1.84v vcore.I uncap the chip and give a try.

First I had problems to get a good contact. But reinstalling the stuff at least 3 times I managed to get good bios temperatures. Then I started to boot window; computer shuts down chip was dead

It was a hell of a chip, one of those that can prime for hours at 3GHz with a good watercooling system.
I will never no if it would have done 100% oc And won't be able to bench with it

Did you try a higher HTT with a lower multiplier to make sure it's not the HTT?

THat's already a heck of a result

[T_M]

Would really help to know what motherbroard and BIOS you are running if you want a hand with BIOS tweaks

[Kasparz]

He already sad 310p, so if 310p, then DFI UT board.

[CRUSH-ER]

IHS removed? If not, that'd probably buy you something, if ever so small. Looks like you are probably getting close to reaching the limits of that chip already.

And it's a damn fine chip.

[Waus-mod]

Htt is prolly to high... This will block youre oc i think.

[CRUSH-ER]

Yeah but he's in a tough spot because a stock Venice is 10x and even 10x is too high.

[Waus-mod]

Well 10x will give him some room to go higher...

[CRUSH-ER]

Possibly. But still....his HTT is pretty damn high as it is. He'll still need 350+ minimum.

I didn't give a chance to a 8x multiplier, I thought the DFI would have trouble to reach so high FSB under phase. I'll do this soon thanks.

Yes DFI Ultra-D and this one is OK; I compared the results with my epox a while ago.

According to this thread: http://www.xtremesystems.org/forums/...ad.php?t=74319
2 WR were beaten IHS on: venice 3000+ and 3200+
I will remove it at last, if the oc is worth without it I won't be able to put it back.

I don't think I reached the limits of it. Any good venice 3000+ can do 3500MHz, this one is real good I want 100%

Htt is prolly to high... This will block youre oc i think.

I hope not, Venice 3000+ WR is 3644MHz I'm sure I can reach 3600MHz
Do you think SATA can limit FSB ? Is worth to find an ATA drive to install OS again

[UTF Nightmare]

HTT is high indeed. Try on lower MP first to know if your DFI isn't the bottleneck
390 is quite high.

Nice OC btw

[CRUSH-ER]

I'd definitely try using a pata drive. SATA limited few of my max clocks before. Disable your nic, sound, etc. Probably already did that though. And don't use PS/2 (you probably aren't.)

[KoNiaK]

Yes I disabled lots of those things, but what is 'nic'?

I will try with a PATA drive, the trouble is to find one :/

Is it useful to disable stuff from the chip, such as cash or elese?

Which bios would you advise?

EDIT: thanks for your help

[CRUSH-ER]

Onboard nics (network interface card). DFI Ultra-D has two of them. Disabling SSE/SSE2/3 instructions in the options should help also, though since those fellas have it enabled, it'd be considered something to the effect of LOD cheats on videocards. Of course better cooling is probably the best option. What exactly are you running right now? Single stage phase? 704-2BTA is a good choice for a bios.

[KoNiaK]

My bad yes I disabled network.

I'm using PS2 since I disabled USB So I should disable PS2 and use USB keyb&mouse?

Mach2, but to change isn't an option, I don't have enough time to look for the better one.

I'll try this bios and all the setings this afternoon if I can.

Thanks.

[CRUSH-ER]

I always disable USB and use PS/2 until about 300-310 HTT. After that, most definitely disable PS/2 and use USB. PS/2 craps out for me at really high HTT.

[T_M]

623-2BTA is another good BIOS.
WHat symptoms did you get Crush that led you to believe PS/2 was crapping out?

[CRUSH-ER]

Well for one....losing the mouse and keyboard suddenly during use. Playing a game and BAM! the stuff just dies like it was suddenly disconnected.

[afireinside]

uh ldt multi @ 2.5? You can't really tweak for an SS... I'd like to know what the CPU can bench at with a real ram config.

[CRUSH-ER]

^ Good suggestion.

[setyotomo]

hehe maybe you need more vcore

this is what i get couple months ago when breaking WR (just stand for a week before cpuoverclockk hits a new one)



i'm using :
DI with -28C with IHS not removed
PATA HDD
ldt x2.5
AMD 64 Venice 3000+ 0517 EPBW
DFI NF4 Ultra-D R.02 - taiwan board - korean chipset -
BIOS 5/10-2 Fixed modded by Merlin
1x512 single channel
VGA PCI S3 Virge

and all network disable including firewire, USB enabled

[kiwi]

Not all chips like vcore. It can make things hotter and less overclock especially at high HTT >330.

704-2BTA is a good choice for a bios.

Yeah, in fact, it is the one that let me reach 3.7Ghz

Nice OC btw

The dfi NF4 ultra-D boards can get huge HTT's; here's a link of my friends board that I have tested.

HTT=460 @ 1.7v, stock bios, watercooled, I haven't disabled anything in the bios, so prolly it would go a bit higher

As long as cold bug doesn't hit in. On water/air sure, no problem

[KoNiaK]

I didn't find how to disable PS/2 so didn't give it a try, but don't think it's really an isue.

Yes I know, WR is 3644 die@-21C; it is real close

I tryed 3 different bios and didn't see any improvment, are you sure the bios have anything to do with you reaching 3700
