Hi all, I've been following this great forum / thread for a while. Anyway I just became a member and I?m having some problems.
I did the cpu volt + bsel mod (e4500) and at 300fsb I?m stable, all except for the blend test that fails after 4-5 hours. The cpu test runs all night and passes.
I run memtest86 all night with stock fsb and it passed. I then run it with 300fsb and it fails on test #7.
I'm at vagp 1.72 + vtt 1.52 atm.
My ddr2 is rated for higher speeds than 300.
I've tried heaps of bios settings you guys recommend but the blend test still fails. I'm going to run memtest tonight again after the board mods and see if it?s still the same test that fails.
Anyway I don't know what else to do.
Before the board mods I was stable at about 285.
I've been testing for the last 5 days and I just don't know what else to try.
The temp is fine for everything.
More vagp? More vtt? (I think I?m already pushing the vtt )
What do you guys think it could be?
Any help would be greatly appreciated. I don't want an extreme oc, I?ll be happy with 300.
Thanks in advance
Running at 3.3Ghz is excellent for this mobo, however firstly although you list Vtt and Vagp volts levels, you say nothing about the Vcore or Vdram levels you are using ?
Yes, you are pushing Vtt a bit, certainly higher than I would recommend, however increasing Vagp to 1.8-1.9v levels may help resolve your problem ---> the fact that memtest fails at 300 can either mean a memory fault or a chipset/cpu overclocking fault . However if 300 overclock problem is not resolved with Vagp at 1.9v then doubt that lack of Vagp is sole reason for issue ?
Since a 4coredual is not that great when considering Vdroop levels, it could simply be that the 3.3GHz loading is just too much for your particular mobo's Vcore supply ---> meaning even more Vcore may be required ?
And are you still using original Intel heatsink? Although you say temps are fine for running 3.3Ghz, part of your long term testing issues may be that cpu "temps" are not good enough ? For example, my E4400/4coredual setup at 3.2Ghz only ran properly stable after I changed to using a Big Typ 120 VX !
