While higher frequencies appear to function initially, -and in fact function when only one CPU package is installed, dual -CPU package systems will lock up after around 6 - 12 hours of uptime -due to presumed HT link errors at the higher (>= 2.8GHz) HT clocks. - -If applications are not being used that stress the coherent fabric, -then the uptime before hang may be much longer. Users attempting -to overclock the HT links are advised to "burn in test" the HT links -by running memtester locked to a node with no local memory installed. - -Change-Id: I8fae90c67aa0e8b103e9b8906dea50d1e92ea5a9 -Signed-off-by: Timothy Pearson <tpearson@raptorengineeringinc.com> ---- - src/mainboard/asus/kgpe-d16/romstage.c | 5 +++++ - 1 file changed, 5 insertions(+) - -diff --git a/src/mainboard/asus/kgpe-d16/romstage.c b/src/mainboard/asus/kgpe-d16/romstage.c -index d1b75b6..8f1ec35 100644 ---- a/src/mainboard/asus/kgpe-d16/romstage.c -+++ b/src/mainboard/asus/kgpe-d16/romstage.c -@@ -349,6 +349,11 @@ void cache_as_ram_main(unsigned long bist, unsigned long cpu_init_detectedx) - - struct sys_info *sysinfo = &sysinfo_car; - -+ /* Limit the maximum HT speed to 2.6GHz to prevent lockups -+ * due to HT CPU <--> CPU wiring not being validated to 3.2GHz -+ */ -+ sysinfo->ht_link_cfg.ht_speed_limit = 2600; -+ - uint32_t bsp_apicid = 0, val; - uint8_t byte; - msr_t msr; --- -1.7.9.5 - |
