I think DFI recomends disabling errata 94 and auto for 123
Hello, just wondering, CPUs with the same stepping and batch number should perform just about the same in terms of overclocking when compared with each other?
don't think you can have the same batch number :rolleyes:Quote:

Definetly leave errata 94 disabled as it will give you trouble with instablity, as for 123 I usually leave it disabled as it affects memory bandwidth.Quote:

When enabled, the processor will not bypass the L2 cache to prefetch data from the system memory.
When disabled, the processor will continue to bypass the L2 cache for certain cache line fill requests. This improves its performance.
When set to Auto, the BIOS will query the processor to see if it is affected by the bug. If the processor is affected, the BIOS will enable this BIOS feature. Otherwise, it will leave it disabled.
If your processor is affected by this bug, you should enable this BIOS feature to prevent the processor from hanging or corrupting data. But if your processor is not affected by this bug, disable this BIOS feature for maximum performance.
so how would you test whether the CPU has the bug ot not
can you think of a way to force the CPU to prefetch data from the ram,,, im not sure at all how to put it to test,,,Quote:

mag|c>curious, which shop in Denmark did you buy this from?
Did not think anyone had them in stock here yet ;)
Update>aaahh found it ;)
man, this is just plain weird, core1 prime's away 2900Mhz <1,45v and core0 will fail, >1,45v core0 will prime and core1 will fail!
Also temps it sky high 52-56 degrees at 1,47v with CNPS 9500, and 70++ degrees pwmic - I have put a 92mm fan above now it'll say below 55, that's just sick since it never went above 45 degrees without cooling with my san diego.
I think the limit for this chip with my cooling will be around 2850mhz, one day I'll be brave and that of the top, but I just saw a picture of a topless 170, smd thingys on one of the sides is just next to the epoxy. (Seems a little more tricky than with my ol' venice...)

see my sig for my latest stats... and i still have a ton of room to work with! grats on everyone else' great 170's as well!
so there is hope for th enewaer ones then......Hmm will i buy ir not ?
this cpu seems to have either a very weird or a weak mem ctrl, my ballistix did 295mhz 2,6v 500% dual win memtest on my old cpu, can't even get them stable at 275mhz 2,7v now.

I think I might take the chance and remove the IHS this weekend, but the cnps 9500 is so darn heavy, so I'm wondering where can I buy the foam pad the Athlon XP chips have on it?
-
Anyway here is the picture update! :D
It have just reach the 20 minut mark at the current setting. :woot:
Edit: 35min and still going ;)
Just wanted to show you all how I tested the mem ctrl.
Settings were what's on the priming picture but with 10x275 and less vcore!
I tested drive and data strenght ONLY, with windows MemTest running one session set to 899mb and another one set to All unused RAM, this was the result.
55min memtest = 430%
Edit 2: bah something failed at 38min :s
So..I maybe an idiot, but how did you solve this?...by tweaking drive strength/data only running at 1:1?Quote:

Drive/Data 5/1 seems best, 7-6/3 were better on my old cpu.Quote:

Nice result @ that Vcore :)
We want more Vcore :p:
