I was looking for Qxxx Intel processors, but no way to buy this. BTW I was wondering what is vNB mod doing. No difference in MHz, even while I set about 2.2V or more. The reason of poor frequencies ( < 230 MHz) on a i815 is that I had (we all had) a poor CPUs. So, this is another great Intel chipset, no doubt.

I think Vnb may yield some stability for long benches @high FSB + tight timings. I plan to check this somewhere this week when I find my best Coppermine 733. I don't think that Vnb effect can be seen from CPUZ valids.

It will be very helpfull to get something like a WBX tune utility for this chipset. Memset can operate with i815, but it is not enough while squeezing platform to the edge of performance :)

He wrote "QS cpu". This is an engineer sample of this processor, has got unlocked multiplier. I guess it is not mobile. Unlocked intel processors are quiet rare. I don't have any :(

Yup, unlocked multiplier is very good for reference clock. That's why he did almost 250mhz on air. I did almost same score, but on locked cpu. So this score is only quite good :)

only 1 limit on reference clock, its mobo. i think i can rich same on p3 1133, it doesn't matter.

 

ps QS = qualification sample.

 

Sure, you could reach the same on locked cpu.

 

Using locked cpu is just too simple :P
