AMD 64 2800+ Overclocking

[Guest]

Archived from groups: alt.comp.hardware.overclocking.amd (More info?)

I am currently running a Barton 2500+ overclocked to 3200+ on a Asus A7N8X.
Two years now and no problems.
I am in need of another pc in the house so naturally I want to upgrade mine.
What kind of overclocking can I expect on a Athlon 64 2800+ with a Asus K8N
board ?
I plan to reuse my 2X512 meg Corsair 3200 LLPT ram chips but I will
eventually want to upgrade those too.
Is the CPU multiplier locked at a certain level on this chip or can I change
the FSB and multiplier too.
Should I be looking for a specific code of processor ?
What kind of speeds are you getting with this rig ?

TIA,

Big Red

I've been working on my 2800+ the past couple days. So far it's running at
2106mhz.There's a few problems with my mobo/ram combo. For some reason the
BIOS sees it as 333(166) so I can't choose 200 FSB as a start.Right now the
ram reads at 190 FSB but CPU reads at 2106.
There's a BIOS option for A64 mobo's. It's the HTT bus. Default speed on
this is 4x.I had to change it to 3x to get above 219 FSB. I'm using a
Chaintech VNF3-250(Nforce3 chipset),BuffaloTech PC3700 DDR.
I had to raise the CPU voltage to 1.65v and DIMM voltage to 2.8v. This is
using the heatsink/fan that came with the CPU.
I think if I had better ram or maybe more BIOS options I'd be able to get
more.

its your lucky day

i built a system for a friend using the exact same cpu motherboard combo,

the bios is light on o'cing options to say the least.
you can adjust the mulitpliers, but you can only use lower ones(2800+ has 9x
as default), whole numbers only
you can adjust the ht bus, but i'm not sure how much,
there are preset oc's 5% and 10% i think
not much in the way of voltage options for the cpu or memory
and i think you can adjust the fsb can't remember how far though

as the system wasn't mine i didn't do much with it,
apart from that its a great board, tons of stuff onboard audio ports, spdif
in and out, cnq, wish i could have one myself(still on skt a, lol).

for overclocking options abit's nf-8 might be good, read the reviews, but i
always said i would use this board if i was gonna go 754.

hope that helped

9x266 should be easy.

Doesn't matter.

Locked at max of 9x.

Just go for the latest core. I think that's newcastle, but not sure.
Sorry, don't have that combo, but if the board will allow a FSB of 300,
you might be able to get 9x300, but I wouldn't count on it.

Suggest you start a little higher than the 2800. You want to shoot for
around a 3600 speed. So start with a 3200 or 3400 cpu.

I think the cpu's are cheaper than the fancy high bandwidth ram.

He can get the same speed out of a 2800+ as he can out of a 3400+, for a
lot less money, so why pay more?

You don't really need real fast ram. Even with PC2700 ram you can clock
the FSB to 266MHz without overclocking the ram. You don't loose as much
running out of sync in the K8 as you did with the K7. And now with 512MB
of PC3200 ram below $35, well, that's fricking cheap.

ick PC2700 Let's think positively here:

[excerpt from new E core review]

Every time a new Athlon 64 processor core come out AMD engineers
continue tuning up their integrated memory controller. Note that this
is done not only for the sake of increasing the processor performance,
but mostly in order to extend the compatibility of this memory
controller with the different DIMM modules and their configurations.
The previous 90nm Athlon 64 processor core aka Winchester had certain
performance limitations when four DDR400 SDRAM modules were used. If
there were four single-side DDR400 SDRAM DIMMs installed in a system
with a Winchester based Athlon 64 CPU, they could only work with the
2T timing, which caused a few percent drop below the usual performance
level. If there were four double-side memory modules installed, DDR400
SDRAM would not work at all and its working frequency would
automatically drop down to 333MHz.

AMD engineers promised to eliminate this problem in the new Venice
core and they did keep their word. Athlon 64 processors based on
Venice can work with four single-side DDR400 SDRAM modules without any
limitations, and if there are double-side DDR400 SDRAM DIMMs
installed, they can work at 400MHz with 2T timing.

Besides wider compatibility of the Venice’s memory controller, it also
got noticeably faster. Among the tweaks implemented in Venice we
should definitely point out enhanced hardware data prefetch and more
write combining buffers (4 instead of 2).

All these improvements should help Venice based Athlon 64 processor to
outperform their counterparts based on the older core revisions but
working at the same clock frequency. And the performance gain will be
more noticeable if there are four memory modules installed in the
system.

And how do you propose he install a S939 cpu in his S754 MB? All this is
interesting, but has nothing to do with the original question.

Tell you the truth, I read the E-core review after the first post and
jumped socket camps like a dog. Looks like they finally got out of
beta mode with the on-core memory controller and are ready to roll.

Just joking on the pc2700, if you want to do that, fine.

Thanks for all the info. As usual these groups are a great resource.
What about the mobile Athlon 64 are their multipliers locked as well ?
I read where they can be overclocked better but can be a bitch to get a fan
installed on.

Thanks again ...
