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
Welcome to Anandtech !
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 !
Hi Jimmor,
Thanks for your quick response.
Ok here it goes.
My vcore is 1.41
My vdram is at the standard for my mem 1.8v (I have it set to high but I can't see any difference from norm inside cpuz)
I replaced the stock heatsink with a TR 120XP from my old system with some AS5. My case has 5 fans
Temps are about 60idle - 75max. (Depending on the weather) I even seen them reach 80 when it was a really hot day
Today is a cold day and my core's don't go over 65c-66c while testing, but it still failed before.
Mobo temp (what I?m thinking is NB? in everest) usually sits near 30c - 33c. After this vtt + vagp pump it?s at 41c, I installed a fan over the NB HS before upping the mobo this high.
I didn't want to give my cpu any more volts seeing it was already getting pretty hot. But like it did pass small ft test all night (19h). So I thought it was already enough for 300.
I'm testing right now. But from mem my bios sort of goes like this.
Cpu: everything disabled except for boot guard. Locked pci/agp
Chipset: I tried both inputting most of the ddr latency?s and keeping everything on auto except for the 266.
Dual Chan, 2T
adv option (that pipeline option = enabled)
ddr + agp volts to high
vlink = normal
pci delayed = enabled
drive strength to ultra high or high. I?m only using optical drives on the ide chans (no hdds)
Thats about all the major ones I can remember. I'll report with this if/when it fails, should be pretty soon its reached 5:40h. (keep going baby!)
I though I was pushing it with the vagp (maybe I just got confused)
I think I am pushing the vtt a little; I was trying to follow your recommendation from the other thread. I?ll lower it to 1.5 when this test finishes.
btw nice catch on correctly identifying the vtt voltage.
Also my under my HS it says it?s a pro not ultra
So you say maybe some more vagp might do the trick.
You've just giving me some new hope. I'll try pushing it a little more, starting at 1.80 and going to 1.95.
Think I should be safe going up to 2.00v?
Should the pcie pipeline option be disabled or enabled?
It?s just on auto. I'm running a Leadtek 7800gs agp so didn't think it would matter.
Thanks
