Biostar TP67XE motherboard discussion thread (w/template) - Page 72

I usually use fixed as it is more stable and doesn't bump the vcore too high. So, yeah, use fixed. Try that and see if that works. It worked for me.

I've had this board running pretty stable for about a year with the same overclock as post #606 (a seemingly very popular overclock, thanks Scorpion667!) I would get a blue-screen every couple of months and it would always be at idle, never under load. It was Prime stable and I could run a handbrake batch for 4 days straight without a problem, so it was good enough for me.

Well, recently I bought some extra ram (because it was on sale) so I went from 8 gigs of the 30nm Samsung ram to 16 gigs (4x4.) The ram is overclocked to 1866, 1.36v, 9-9-9-24.

With all four dimm slots populated I'm having issues. Using the same settings as before, the machine is Prime stable. But overnight I'll get a blue-screen. I have automated encoding running at night, but it never pegs the cpu at 100% (MCEBuddy.)

I've tried upping PLL to 1.75 and it didn't work. I've tried to up offset voltage by .01 and it didn't work (trying .02 now.) I've upped RAM voltage to 1.5v as well as resetting it back to spec and it didn't work. The computer is stable however, with no overclock at all. Could somebody help me out?


O.N.E.

I ran nearly a full day of video encoding with offset voltage at +.02, and CPU PLL at 1.8 and my system appears to be stable again. It makes me a little nervous that my core voltage under load is at 1.38v but will sporadically hit 1.41v, and it rarely falls below 1 volt at idle (usually hovers at 1.008v.) It seems like I'm using a lot of voltage for 4.7 GHz.

Are my results typical, or is there something I'm missing?

thcomb i wouldnt use offset if i were you. the voltages spike up sometime. 1.8vcore is dangerous! use fixed volts instead. switch off loadline, enable cpu pll override, use fixed vcore mode. for 4.7ghz overclock i use 1.37vcore. but all chips are different.

Sorry, I missed a key when typing. Vcore is usually at 1.380v but will spike up to 1.410v.
(1.8v would be nuts!)

Am I still a little far out, considering I was at 1.368 with just 2 RAM slots populated? Temps usually max out at 70C when using Handbrake (same as before.) Prime has always been a little over 80C for me, and now it might be a degree or two hotter. I know 80C is uncomfortable for most, but it never gets that hot otherwise.

hmm yeah it could have soemthing to do with the full 4 dimms. you might have to bump the memory volts a tad bit and the memory controller volts a bit also. i was told before that getting 2 more rams from a different package as your initial 2 rams might cause problems.

You know, I didn't even think about having to raise the memory controller voltage. (This is my first computer with 4 populated dimms, as well as my first overclocked computer.) So, I reset everything to the way I had it before, but bumped up the memory controller. I'll report back how it goes.

I'm really trying to make offset voltage work, but if this doesn't work, I am going to give in and just go with fixed vcore like you suggested.

Just curious, but does anyone use the mobo speaker with this board?

So upgrading to Ivy Bridge, have my 3770k, some cheap pny 2x4gb 1333 9-9-9-24 1t 1.5v (runs those specs at 1600 just fine with my 2500k at stock or 4.5ghz), but the turbo multi has disappeared in the BIOS with the latest version. Anyone have any ideas? Thanks.

So i need to resurrect this thread.

I have the TP67B+ which does not have the extra power phases but does have the same problem with the bios where offset+LLC cannot be enabled together, i think this is hindering my ability to get a high stable overclock (4.6+)

I refuse to run fixed volts (where disabled LLC is actually enabled) so that is out.

I have emailed biostar but they have not responded to me.

Closest stable 4.6 OC ive had is 6 hours of prime before it crashed, this is at 1.38v. Makes sense to me that not having LLC would produce this kind of random crash 6 hours into a stress test, can someone else confirm my thoughts?
