Venice you are killing me....

[chrisbard]

Soooooooooooo boyz and girlies I just meet Santa and he gave me one Venice 3200. I borrowed one MSI K8N Neo2-FX until my epox board arrives and there is no way I can up the FSB without loosing the stability. What the hell is wrong? I need to mention that I have little experience when it comes to A64 field. Any comments will be appreciated...well...almost all...

[danrok]

There is no FSB, it's known as HTT on A64's.

First off, what HTT multi are you using? (Not CPU multi)

WARNING! This is a VERY different beast, let Danrok take you by the hand and lead you through it...saves on those bumps to the forehead.":O}

[chrisbard]

This is what I have now as default !

4x (the board is based on NF3 250GB chip)
there is no 5x
HTT is 2x800 = 1600 and some progs report that it can go up to 2x1000=2000

[danrok]

Surely you will fry it at 1600Mhz?

Mine is something like 4 x 250Mhz.

EDIT: My HTT is 5 x 210MHz.

I can't see that your HTT could be at 1.6 GHz.

[robbie]

You'll need decent memory. The Geil stick that I had in mine was killing me. Took it out and now it clocks higher.

[danrok]

Doesn't your CPU have a 11x multiplier?

[Exile69]

No the 3200+ is default 10*200 for 2Ghz. I think i know what he means when he said 1600Mhz. nForce4 boards have a max HTT of 2000Mhz, which I think is full duplex from 200HTT*5(HTT multiplier). His max HTT is 1600, full duplex, 'cause he's running an nForce 3 250 board. So his max HTT multiplier is 4x*200HTT, which yeilds 800 and then full duplex yeild 1600Mhz if I'm not mistaken, which is normal.

So, when you try and OC, Chris, make sure you drop that HTT multi to 3x to avoid going over 1600Mhz HTT (full duplex).

[chrisbard]

I have droped the HT ratio to 3 and now I have 3x220x2 = 1360
Proc is running 220*10 = 2200 Mhz

I had no problems and I will test it further.

One Q 4 U guys:

The Venice runs at 1.36 V / 28 C and I want to know where can I take it in case I would need a little extra voltage 4 stability.
Also how much more can I add to for memory?

Thanks a lot guys for the advices !!!

I have installed Windows 64 bit and with Sisoft Sandra 64 bit I got nicer results as with 32 bit versions of XP and Sisoft ! I am wondering if there are any games that would benefit from Win64bit version (made 4 64 bit)??? I have installed Chronicles of Riddick on XP Prof and this game takes advantage of A64 but in the readme it only talkes about win xp and nothing about 64 bit ed. I guess the game was out before 64 bit hit the market.

[MONKEYMAN]

On stock cooling try and keep voltage beow 1.6v, you should be able to get upto about 2600mhz with little problems with a decent psu.

[Exile69]

64 Bit Windows is still really buggy. I know Steam is now 64 Bit and I think Far Cry is as well. I think it'd be better to just go back to 32 Bit Windows until Vista is around or 64 Bit Windows is improved.

[chrisbard]

Yeap in Win64 isn't working until I find some drivers (if they exists)! Leadtek $uck$ big time !!!

[danrok]

I looked for TV Tuner drivers for ages and gave up.

[SteveI]

Don't even try to up the HTT much higher without killer memory. Keep in mind most DDR maxes out at 220 or so. Run asynch, 5/6 and you should easily get 2.3-2.4 ghz even with stock voltage. Run memtest... your memory will top out well before your CPU does.

Both of my venice cores did 2.3g with stock voltage.

[chrisbard]

I am keeping the mem at 166 manually that means it'll go up not much. Mines are indeed failing at more than 220. I am changing my memory too so what mem should I buy? Some DDR 3500 would be good?

[SteveI]

It depends... If you are a big believer in running in synch... the faster the bester. Remember PC3500 is only 217mhz. You may not get any boost at all.

Honestly, I'm happy running asynch, one of my A64s is at 2.5g, running memory at 180mhz... the other is 2.45ghz w/ mem at about 225 or so.

If you want a hope of running synch, you're looking at memory that can do 270-300mhz, not easy with DDR. I'm looking forward to DDR2 onA64 where 300mhz memory is feasible.

I've been running it for about the last 3 months without too many problems.

[danrok]

More a case of buggy drivers?

Some will have more luck depending on what hardware you have.
