Stock voltage for 3200+

K.O.Kiki

Just a really quick question (cos I can't find the answer on AMD's site): What is the stock voltage for an Athlon64 3200+ (2Ghz) supposed to be?
I'm asking cos I'm making a new PC for a friend, and OC'ing it mildly for him.
So far I'm stress-testing it at following values:

• Memory divider at 1/2 (ie 200)
• CPU at 205x10 (2050mhz), HTT x4, 1.350v to CPU

It seems stable so far, but I don't wanna go further until I know the stock voltage:o

someone posted up a jpeg of the voltages for amd chips, i have the jpeg at home, il post it up when i get home this evening

but that voltage is fine, i had mine up at about 1.5v when i was ocing my 3200 (socket 754) on air cooling
is it socket 939 or 754? and what cooling are you using?

K.O.Kiki

It's skt939, I'm using the AMD stock air cooler.
It stress-tested stable at 210x10 @1.35v as well, trying for 215x10 @1.35v now

you should be able to get 230 or 240 x10 at 1.4

Stock voltage for the venice chips is 1.4 volts so you are under volted

Set it to 1.4 and then start overclocking

thats if it is a venice core

conzy

yup:p

Is it S939 or S754?

If its 754 its a 130nm chip and stock voltage is 1.5.........

^^^^^^^

Damn it:o

We still dont know if its 130nm or 90nm..........

CPUZ will know:D

K.O.Kiki

Yeah it's Venice (sorry should've said).
However, it ran 30mins of Prime 2004, 220x10 @1.35v, temps around 41C.
I'll up the voltage if 225 needs it (and I'll run a much longer Prime 2004 when I find my max)

*edit* 225x10 @1.35v already passed, doing 230x10@1.35v now

conzy

Give it 1.4, your just wasting time with 1.35............

K.O.Kiki

Yeah, but the temps will go up...
Since it's not for me, I have to keep it cool & quiet, see. So, I want to keep the max temps around 45, otherwise the fan might be a nuisance.
I'll up it to 1.375 for the next OC - 230x10 @1.35v seems stable as well.

just buy a heatsink for like 20e.actualy i could sell you my artic freezer 64 pro soon.

1.75 FTW :eek:

Thanks guys -- seems I was too optimistic :rolleyes:
It runs fine if I OC in WinXP, but not from BIOS -- and I'll trust the BIOS anyday!
So I'll do another series of 230x10 tests (and yes, it was stupid of me. I know; I'm kicking myself ATM...)
I'll start at 1.4v; be back in an hour

Good luck, dont be afraid to up the voltage, Lots of people run the venices at 1.6, but I would be more comfortable running it at 1.55vcore;)

I think I can guess the culprit -- it seems the mobo won't let me boot WinXP above 227x10, no matter how much voltage I apply.
However -- it's not my PC. And since it won't be used at any high resolutions for a while, I'll settle at (227x10@1.3875vcore) or maybe a bit lower - a nice 10% boost nonetheless(yes, I know it's heresy to be done after such a small boost...)

your using a memory divider i take it?

K.O.Kiki

I was - set to 1/2 (ie, 200)
Am now trying to figure out how to put memtest86+ onto a USB key... I don't know why it's not doing anything...

conzy

A 1/2 divider is a bit extreme, the ram is running at half its rated speed and that could be causing instability.........

Even the Shuttle SFF PCs can get a better overclock.......

Try again with a less extreme divider like 5/6

K.O.Kiki

I will, but for now I'll look at the RAM itself; see what I got to work with there (it's OCZ Premier DDR400)
