3000+ Venus Overclock

[aatf510]

Hi, I just get my gf a new computer, it includes a A64 3000+ (Venice), 2x512MB Corsair Value, DFI Lanparty nF4 ultra, and she's using my Zalman 7700cu.

I have heard that Venice Core o/c fairly well, so far I had been ok @ 2.0GHz @ default voltage, however, I couldn't go higher than that. I had tried it with 1.5v but it would halt and give me a blue screen right after WinXP started.

Am I doing something wrong?

I had been using the divider to keep the memory under 200MHz at all times.

Now I can't help but try to imagine what a Jupiter over-clock could reach !

We never know with those gas giants, they need one heck of a cooling system, very expensive.

If you are running Value you ram, I assume PC3200, 200mhz is your limit..

Stock is

9 x 200 (LDT multiplier @ 5x)

You want to keep the total number LDT X (HTT speed ) below 1000mhz.. You can go as low as 400 and not lose much performance at all.



In your BIIOS you should have a memory divider as well.. You memory is only rated for 200mhz, so once you push past 2ghz..You already way out of spec ( about 225 mhz..)

Put that divider in place and start bumping up the speeds.. Put your LDT multiplier @ 3 and go from there.

I have lowered HTT x 5 to HTT x 3, but it's still giving me the same error.
It seems that I could easily get into memtest86+ with stock 1.4v even at speed like 2340MHz, but I am unable to load into Windows, it just halt and stop right at the welcome screen (no blue screen though).

If you are lucky, you can oc to 300*9=2.7GHz

have you tried using a divider to take your ram out of the equation?

check out zebo's sticky...
and also, it's a venice.. not a venus hehehe

bump Vcore up to 1.45 or even 1.5 and go from there..

Give your memory 2.7 or 2.8 reguardless.

It seems that the memory divider on this board is not working correctly.
