I'm at a complete loss atm I had a P35 board from gigabyte before but was having some trouble with a resetting bios so I decided to get this board but I cannot get it stable..with the p35 the settings were simple and it was able to run orthos blend nearly 15 hrs+ fine..at 4ghz and the ram at 890mhz at 5-5-5-12 (btw the ram is 4X1GB patriot low latency) for over a year

With these current settings I'm able to get to the one hour mark then orthos will fail.

MCH from 1.2v - 1.28v all get the same time within a few mins of each other 55- 1hour 7 mins was the longest it lasted. 1.3v and windows will fail to load just reboot If I change ICH it will fail within 10 mins that stays at 1.2

If I change anything to do with the cpu (pll, termination, ref) other than normal and the Vcore I have it set at it will fail within 10-15 mins. Vcore even 1 down will faill within 5-10 mins... 1 up same thing

Changing the system memory multiplier to 2.00B I get the same problem of failing within 10-15 mins 2.00D seems to be the only one that works

I left those bottom settings enabled it didn't seem to make any difference

Hopefully someone can help me out here I don't know what to do anymore lol

Thanks

try 1gb of ram at 2.1v, 890mhz. just increase cpu vcore and keep all mobo options auto. 445x9. quick way to see if your mch volts or ram is limiting the oc. how much vdroop from 1.3625 vcore?

Good luck

orthos is currently running right now in cpuz it says its using 1.328v will try with the 1 gig of ram

your ram/cpu can perform differently on a new board. you need to do a bit isolation testing.

just to remove ram as the bottleneck, relax all timings to case 5-5-5-15, test it individually to find out the max it can do at 2.1v. use memtest86+. keep the processor speed low during the ram test. crank the multiplier up. once that is done you can safely know the max limit of these rams at 2.1v/relaxed timing.

then go test the cpu. but rule out the ram first.

2 freakin days I didn't know what the hell I was doing I turned the mch ref down to 0.720 this morning before I left it's now at 12 hours and running orthos blend after reading about it on a thread god damn

link to thread? I'd like to check that out.
