минуса вторая голова не дает, но и какого-то заметного прироста тоже. ядер больше, загрузка вроде как ниже, но предел до наступления тормозов +- тот же
Now - all 5520 chipsets i think the first two revisions did not support the features of 5600 series intel chips. Basically you'd put the L5639 in and it would act like an L5520 feature wise.
These boards were all replaced if requested - which may affect used motherboards but probably not in live machines shipped with a 5600 series processor.
Read the errata on the tylersburg 5520 chipset and you will be AMAZED how buggy. ie power management for pci-e didn't work - FIXED - Increase the TDP of the chipset and disable the feature LOLZ.
