i can run at 800mhz no problem, what should i be running at? i cant go faster as that causes more problems even though its 1066 memory

P.S. I've seen you mention mosfet cooling before. Does that merely affect (preserve) the mosfets or does it aid other components on the board (or chip) as well? (I saw that picture of where the mosfets were located on the board BTW - cool pic).

while I had kind of a freakish experience that I still don't have the most satisfying explanation for. I added zalman vram sinks to my mosfets and swapped a fan out, and I saw an 8-10C drop in temps on my cores, MB, and GPU. best explanation I heard from anyone is that they were heating up massively (which i could confirm by touching them when the computer was on), which was increasing the resistance across various circuits in the board (general physical propery--more heat = more resistance). this increased resistance was then requiring more current to be pushed through the circuit in order maintain a decent voltage (because I = V/R), which was in turn heating everything up.

but I wouldn't expect that kind of result...and I was pushing >1.5vcore at the time.

FSB: 358 (1432)
Mem: 716mhz 1:1 divider
timings 4-4-4-12-2T

I was able to run orthos for 1 hour at 3.22ghz before my machine froze up. I had the vcore at 1.45, mem at 2.179v, Northbridge 1.56v. I reseated my northbridge with as5, and also put a basic heat sink on the southbridge with as5. My mobo temps are showing in PC probe at 23C. Idle CPU temps are 24C, load seems to have settled at 56C.So with this said any ideas why Orthos is failing?

could be the board's FSB hole, or just insufficient vcore. I don't know how much those 2160's usually need to run.

i'd first try seeing if you're stable at those settings with a 6x multi. If so, then you know it's something to do with the actual clock speed, and not something about the FSB you're at specifically. if you're fine at 6x with those settings, you probably need more vcore. You're getting close to your temperature cap for that chip...I'm surprised the TT isn't getting you better load temps. You sure it's seated properly? Can you improve case airflow somewhere? At any rate, you can see if you're stable with more vcore, and think about cooling options if you get it working.

Finally, you can try a suicide run at 1.75vNB. I wouldn't recommend pushing that constantly, but if you're stable with your current settings and 1.75 on the NB, then it's probably something to do with the specific FSB you're at and you may have to find another.

yup!

That i don't know, but Ravin has gotten that with a G0. I'd recommend going to the main P5N-E thread (stickied at the top of this board) and asking there.

nice! been a long time man what's your PC been up to?

With some tweaking I'm sure I'll get it working at 3.4Ghz stable. My idle temps at 3.2Ghz are around 42c, at load under 60c.

nice work man

is this normal for this board?

vcore = 1.26878
memory=2.178
nb=1.56
100+mv

is that stock voltage for your RAM? you might try lowering it.... the most likely explanation for why you can't OC your RAM as far now is that your board is having trouble delivering enough power to all the components, and something isn't getting enough. have you tried 3 GHz at 1.39vNB? If you can reduce that that might help as well...on my chip I can get 375FSB on 1.39.

haha Hey guys.

Well, it got real busy for me a few months before the wedding, then, of course, the wedding.
Then the honeymoon, rough times at work, best friend moving in for a while, and plans to open my own sub shop started with my dad and uncle, so that itself has taken quite a bit of time.
Oh and bought a new car for the wife and refinancing my atv, doing bill consolidation... yada yada. lol.

Anyway, I can't believe what I started here, lol, 481 pages on a single motherboard. Amazing!

Glad to see a lot of new faces. At some point I will go through the hundred some odd pages I have been gone and update the main page etc. Glad to see the old faces too!

yeh i have tried it @ 1.39.

ballistix pc8500 require 2.2v.

what vcore should i need roughly for 3ghz on a quad on this board? could be im not giving it enough juice.

What are you temps at your current vcore? Have room to warm up? bump it up 1 or 2 notches. Run, if it boots, monitor temps. If its too hot... you've got too much Vcore.

I found that a lower Vcore was more beneficial for OCing my quad. Ultimately I ended up @ 1.22V (VID=1.2875) for the lowest stable @ 3.0GHz, where I started with it at 1.35V trying to clock higher. Keep in mind I got the G0 stepping, which typically has lower stock voltages than the B3 revision.

[ru7hl355]

temps under load is 62-62-55-55 on a b3. vcore wont go lower than 1.26875(VID 1.325), any lower it failes to boot. i do have an CM690 and TR120uE Coming for xmas, but thats not gonna help me clock my memory up much.

think i will to a swap for a GB DS3R as these seem great for what i want to do and the P35 are better chipsets for quads anyways, what do you guys think?

Welcome back man!
Good to see everything is still good on your side.

Congrats on the wedding.

bit it may not need 2.2 if you're underclocking it. also...if you're underclocking you might also try tightening the timings slightly....
