bump vcore up to the next voltage..just a small bump...you will be surprised that the C2D will kinda hit a wall and need "big jump" to get certain clocks

But in your case go up a small amount and rerun orthos...

My cpu
3420 (9x380) on RD600...1.4625 bios but 3508(9x 390) need 1.51875....kinda lot of vcore for 90mhz

5 hrs is not too bad - a small bump might do you. If not, that might be stable enough to leave as-is - before I got an extra case fan mine would fail at an hour and a half on orthos small (stable on blend) but I never saw any instability in games or anything else.

SHould i leave my vFSB and vMCH/ICH as it is now? What's the typical range of vFSB and vMCh for you guys?

Just tried vcore = 1.3750, vfsb = 1.325, vmch = 1.575
Results: Orthos small blend = failed after 54 mins, OCCT = stable, XP = stable, super pi = stable

cpu need more voltage to run small fft which stress cpu the most

from what I have seen here your vfsb/vmch look ok

One more thing from what i have read the best OCing bios is 2333....

[nealh]

nope. one switch.
its a "ON - OFF - ON" switch...

so when the switch is all the way down , its normal... when its up, its in maintanence mode. when its in the middle, its like the jumper is removed - only used when you have a botched bios...

i got mine at homedepot. couple bucks
radioshack should have them too.

this may seem really noobish..but how do you wire the switch to make this mod work?

My Vmch and Vfsb are both one notch above default (not sure the actual values). Orthos small is pretty temperature dependant also - if you can bring the temps down a touch you might not to need any more voltage, that's how I fixed mine. At some point you'll have to decide how stable you need it to be - if it runs orthos blend okay, and occt, and it doesn't crash in windows or games or whatnot, then maybe you just call it stable and live with it, even if it does fail orthos small.

btw, if u were to reseat ur hsf can u apply a new thermal paste on top of the existing paste or do u need to clean the whole thing and then apply a new layer?

clean both the heatsink and the CPU of the old paste. then apply a new layer

Are you sure about this? This is at 333x10 & 1.35V in the BIOS

Idle:


Load:


So I guess I'm lucky my QX runs ok with 1.175V @2GHz... maybe this is the reason it is unstable at 378x9? It tries to work at 2270 with 1.175V?

You're Vcore is still at default which is why C1E is lowering it.

thanx for the reply. I have tried several different setts of ram but no luck. I was liquid cooling the north bridge when my chiller got to cold and condesation shut down the mb a month ago. I pulled it back out the other day and it started to work again but not with 2 sticks of ram. It does not matter where i put the second stick. Even in dual channel or in normal mode it will not boot with 2 sticks. Every stick i have tried works fine on its own. It is running perfect and stable now with 1 stick.

Try your 1 stick in each of the slots just to see if all the slots are OK.

Sounds like it may be a voltage problem. I.E. not enough juice to run more than 1 stick. Do you have a multimeter? You might want to check the Vdimm.

3 pins on the MB header wire directly to the 3 pins on the switch.

[argylesocks]

3 pins on the MB header wire directly to the 3 pins on the switch.

get a 3pin female fan extension... use 3 colors so after you wind them all up pretty, you can figure out where to attatch them to the new switch

interesting ..thanks...bare wires..well that will likely mean I will kill the board or myself(my wife will be hoping for the later...life insurance)

huh? i never said to use bare wires!

just cut off the old fan.. or buy an extension...
or buy one from this guy

I have tried all slots and they seems fine. Can someone please give me link to how i can check vdimm voltage? thanx.

What is key towards increasing the multiplier? I'm running now at 310*11, and increasing my multi to 12 makes me unable to boot into windows. Just hangs at the loading bar until I'm greeted with a BSOD. Increasing voltages makes me see the loading bar a wee bit longer.

My temps are fine (around 40C, under 70C @ load) and can't quite fanthom what's holding me down. Memory and such shouldn't be affected by increasing the multi right?

Also, not being able to get over 330FSB is annoying, but my memory can't take that at 4-4-4-12 anyways.

[argylesocks]

i have this set at default... however, i get a tad bit of studder/flicker when panning around during games.. not sure if its the new nvidia drivers or my low refresh rates or what...

but someone had told me that he had the same issues with the same card, and when he up'd his PCI to 105 the problem went away.
reading some stuff earlier in this thread sounds like i can increase a little.. but 105 sounds too much.

can someone explain what the PCI burn option does? im scared to move it. what is acceptable range?

additionally, i have my 8800 oc'd a bit. will this make a differance?

thanks!

The older is for the 975X chipset, which is being used by the BX2 board. The newer is not useful for you.

OK finally stable at this

vcore = 1.3875
vfsb = 1.300
vmch/vich = 1.550
FSB = 345X9 @ 3105
Idle temp = 42-45C
Load Orthos = 55-60C
Orthos stable = 8hrs blend ok/9hrs small fft ok, SuperPi = ok, OCCT = 30mins blend ok, XP = stable, memtest86+ = 3hrs ok

1. Are my temps ok ? Used to be lower but it rose by 3-5C after i changed the position of my HSF. Need to in order to install my Thermalright HR-05 nb cooler
2. Given my temp and the rate i'm going, would it be advisable to increase vcore to say 1.5 to reach my goal of 3.6Ghz?

Many thks in advance

I have exactly the same setup as you, same voltages, same fsb.

for referance, my idle temps are around 20-22. my load temps typically dont go above 38ish.

i cant tell if you if its "too high" but given your voltage, it seems high.

[hotchoc]

i tune my fans pretty low that's y. i think my hsf needs readjustment

It's another badly named BIOS feature. Basically, it's overclock for the pci express bus. You can't do any permanent harm so tweak it and see what happens.

[nealh]

OK..my board is at my house....

so as I understand it ..I will need to boot with jumpers in maintenance mode...turn off EIST/C1E and watchdog depending on board revision(ie bios)

I have cd to load up bios 2333 as this seems to be the best OCing bios(sans stupid HDD led issue..never plug this in anymore)

is it worth swapping the NB cooler?

This thread is terrific alot of very helpful people....I just hope I can get e6600@ 3500(9x390) and 490 on my ram(like my first RD600)
My crucial 10th anniv ran very nicely on the first one at 5-6-5-5-2t at 2.2v....

[Forceman]

I think those temps are fine.
