Athlon 64 Overclocking problems?

Ive heard you cant use conventional methods of overclocking on the athlon 64. What does that mean for us? Obviously it can be done but is this going to hurt sales? I for one have been waiting on the 64 as I was about to upgrade. Now though if I cant upgrade to the 64 and overclock it, then why should I wait? Maybe the prescott will be the overclocker. Yes its a flamethrower but luckily im getting watercooling 🙂. What do you guys think. Anyone know how to oc the 64?
 
If I understand it correctly, there is no front side bus as we know it... there are ways to overclock, because some sites that reviewed them have used an Opteron 140 and ran it at 1.8 Ghz, which is 400 Mhz faster than stock for a 140. As for multipliers and bus speeds and stuff like that, maybe we'll know later this week when AMD officially announces the Athlon-64.
 
Of course there is FSB only it is not related to memory. The trick it seems will be how to overclock the memory since there is onchip controller but some have already figure that one out. Nothing too complicated according to some that think they know. 😉
The better question is how far it will be possible to overclock it since early indications on Opteron are - not very far.
 
all i got from that news was maybe the soi process renders a chip that is less benefited by increases in voltage
if this is so then our oc'n could change a bit
 
On the retail market AMD holds about 10-12% share. Among overclockers and enthusiasts they have close to 50% share, that is at least I used to read. Meaning if we don't get a chip that overclocks they can pretty much close the house and go to bankrupcy since major manufacturers are not going to bank on new inventions and promises with delays and supply problems.

According to Inquirer the first Athlon64 will be at 2 GHz, rated 3200+ according to AMD. What that suppose to mean we'll see soon.
 
On gigabytes new Athlon64 board they advertised 800Mhz FSB, WTF? What is the FSB on a normal motherboard? Its the link from the processor to the memory? Right?
 
fsb links the northbridge to the cpu
the athlon 64 has an integrated memory controller and thus accesses the memory at whatever speed the memory is running rather than having to go through the northbridge

maybe it's the hyper transport link that is running at 800mhz

Click to expand...

I think Hyper Transport runs at full speed... so a 1.8 Ghz Opteron's Hyper transport link would run at 1800 mhz... I could be wrong though.
 
HyperTransport Technology

-Provides a scalable bandwidth interconnect between processors, I/O subsystems, and other chipsets
-Support of up to three (3) coherent HyperTransport links, providing up to 19.2 GB/s peak bandwidth per processor
-Up to 6.4 GB/s bandwidth per link providing sufficient bandwidth for supporting new interconnects including PCI-X, DDR, InfiniBand, and 10G Ethernet
-Offers low power consumption (1.2 volts) to help reduce a system?s thermal budget
