IF you get the chance and don't mind Saya... which PS and MB is Opp doing his testing with, and is it a "doesn't work at all" @-90C, or just doesn't boot, or ??? Thanks for the thread and the info in it :toast:

I suspect reset/pwr up current demand may be the issue.

Daniel,

That's all OPP wrote in another thread... I think he was trying that on MSI SLI, not sure though... He haven't provided any other info on the open forums as far as I searched. Still waiting :)

I Need an update like crack-head on withdrawal :D

wat is sSOI?
ive only heard of SOI (silicon on insulator) SS (strained silicon) and SSDOI (a combination)
winchester doesnt have SS so that theory doesnt work :)

Any price prevision?
PS:Kick ass score @ -40c and 1.38v,i think I'll wait to catch one of these over a 3000+ winchester.

should be "strained silicon on insulator"

No, it can't be sSoi. If that were the case, FX-55's would have the cold bug as well and most of them don't.

Why the hell do people assume that CBI is correct? :stick: Get your info from PDFs not from software that has been programmed by somebody who may very know less about the issue than you ;)

The FX-55 is and always has been strained silicon-on-insulator or sSOI, AMD publicly declared that at launch :up:

As for the cold bug - there are a number of theories but I personally believe it has something to do with the thermal diode reporting incorrectly, not inherent limits of the chip - AMD changed the diode with Winchester, they changed it again with Venice AFAIK and since we haven't seen new BIOSes for the chips yet (they haven't been officially launched, go figure) it's quite possible this issue could be resolved for all Venice core CPUs.

I remain optimistic! :rehab:

yeah i didn't think about that... hmmm, well its gotta be the diode, i wouldn't be surprised if this cold bug is an anti overclocking issue made by AMD. it would make sense becuase they designate the FX line as their enthusiest proc and conveniently(spell?) it has no cold bug... similarily as we all know its mult is unlocked
but if this where true if then logically there would be a specific temp in which the procs would stop working and all would have the same bug, not just some :shrug:

Those 256MB sticks might have had chips on both sides of the memory module
but are in fact single "banked" alot of people get confused between double banked and double sided DDR SDRAM...

To test the memory controller they will need to use 4x 512MB ram modules, these will be double banked.

wow that was awesome, :slobber: keep up the good work and THANK YOU!
can't wait to see the results on water and air...

Hey everyone! Im new to the forums. i agree and wouldn't put it past amd to have put the bug in intentially. I too remain optomistic and from the results I've seen I am looking forward to seeing what the san diegos can do since that was my next proc to upgrade to. I dont really care a bout a cold bug myself as I use water, As long as I can get a reasonable oc say 4ghz to 6 ghz Id be happy as a peach seed in a field of manure. I just want to be able to do it with 4 sticks of ddr.

no way amd has nothing againt overclockers, in fact the reason that they superlocked athon xps was to stop unscrupulous resellers increasing multi and then charging for a better cpu in prebuilt computers

Kinda off topic... but I just want to say that Saaya has been doing a good job of posting this topic to other forums! I'm sure a lot of people in other forums that don't post on other forums are VERY interested in the happenings of the Venice and don't always know where to get the best info. :toast:

Crank that voltage up man, what the heck you have phase change for! :D
I wanna see maximum overclock not the low voltage. :toast:

Did he get it back from OPP yet to test it some more?

First off, Welcome to XS! :toast:

Second, there is no way that you are gonna see any AMD chips hitting 4Ghz on water anytime soon, let alone 6Ghz. That is Intel territory.

I do believe 4Ghz may be attainable for a San Diego core under a -100C Cascade, but not water. And even then, I'd consider $Ghz on any AMD proc to be far better than a "reasonable OC", as right now that is basically the holy grail for everyone here. Anywho, welcome again and enjoy yourself! This is without a doubt the most knowledgeable and helpful overclocking community on the net. Make yourself at home. :)

LOL Actually, I misspoke I was half asleep when wrote that, doh, I meant 400 mghz to 600 mghz. I now get extra 460 mghz out of my winnie 3500+ on water. I was hoping with a san diego I should be able to 3.0-3.4 ghz on water. With 1 mgb of cache that should be a very nice performer, expecially if it could be done on 4 x 512 mb sticks of ddr.

Hey :d its like a week till april 4th already. haven't they given prelim prices on these?
03-27-2005, 12:53 PM

I don't think AMD will change the prices, as it is simply a revision change. Of course most dealers will charge a small premium in the first few weeks to get rid of the old stock.

This chip has been tossed around for what... 4 days and noone has bothered to test 4x512 1T yet?

Its the burning question we all have. :stick: :(
