Gigabyte EX58-UD5/Extreme Discussion Thread

[tonytiger]

Hi,
I am hoping someone can help.I cannot get bclk 170 and above to fully post (system powers on but keeps restarting until a failed overclock is displayed).I have tried many combinations and voltages to no avail.Below is what i have tested:-

bclk 170 x20
qpi/vtt 1.3 also tried a bit higher
cpu vcore 1.3 also tried a bit higher
dram 1.6
mem multipler x8
unicore x16
qpi x36

All other settings on auto for now

bclk 169 with turbo on is fine (same as above except lower volts ,vcore 1.28 and qpi/vtt 1.28.

Rig:-
3 x 2gb corsair cl8 1600mhz 1.65v
i7 920 batch 3838a820 rev c0/c1
true black with Scythe S-FLEX 1600RPM
gigabyte ex58-ud5 f4 bios (also tried f3 and the new f5a beta)
corsair 750tx
4870 512mb
linksys pci wireless card
1 x VelociRaptor 300gb
1 x wd 750gb
1 x samsung spinpoint 1tb
1 x samsung sata dvd writer
silverstone fortress ft01

This was a treat to replace my old e6600 rig (running @3.6ghz).I thought i could get at least 3.6ghz so i am a bit disappointed.Have i hit the limit of this cpu or is it the motherboard?

Many thanks and a
Happy New Year!
