V8.07是否不支持4核CPU的主机？

sunny2008

俺用的是Q6600（四核）CPU，升级到8.07以后，网卡会反复UP、DOWN。

俺该咋办呢？

4核可以用，目前仅保证双核的稳定性。您所说的问题，不是4核CPU的问题，是网卡驱动问题，具体的是什么网卡芯片，是板载的还是外加的。

谢谢time...
俺在BIOS中禁用了2nd CPU后，问题解决了。
按PANABIT提供的手册中说，超线程会导致网桥数据口失效，俺在BIOS中没发现超线程选项。

主板是泰安S5191，板载2个i82573V GE/1个i82551 FE。

另外，启用V8.07以后，PING出去的时延略微增加了一些（1~2ms），不知是否正常现象？

82573是给我留下印象非常深刻的网卡之一。
主板芯片是什么？

回楼上: intel Mukilteo-2 MCH/ICH7-E SB/PXH-V 64bit PCI HUB/SMSC SCH5027 Super I/O chip

照说明书抄的...呵呵.

请问: V8.07有没有可能增加网络延时,降低网络速率?   今天更新到8.07以后,底下反映打开网页慢多了, 也不知是否是宽带问题巧合了.

Lucifer

我们的用户里目前为止只有你反映有这个问题。8.07只是修复了bug没对核心结构调整

已经换回V8.01了，过几天重装FB后再试试。

请版言帮忙分析一下:
