Gigabyte GA-P35-DS3L Thread - Page 380

post #3791 of 4644
Hey guys, just letting you know, with quad core be very careful with the voltages you pump and the stress you put on this board. There are a lot of cases where the ATX 4-pin has melted because the board only has 4 phase power and cannot handle it.
post #3792 of 4644
If you touch the vcore in BIOS make sure to check after in windows with CPUZ how much voltage is really getting while in max stress (using orthos or something like) because its trial and retrial depending on how much vdrop your mobo has.. for example i have to set 1,8 to get 1,44 in CPUZ.. some weeks ago (you can read it back here ) my house power went down while i was at work.. i arrived home, started the comp (i had left it on) and discovered in horror that CPU temp was 45ºC .. i checked cooler , was about to reseat it when i saw in CPUZ that vcore was 1.8V real.. that was bad (since intel says max is 1,55 or 1,5) i went tot he bios.. and after some trials i discovered that i had to set 1,48 to get 1,44V max... but still a week later, another power short in my house reverted all and the computer was with very little voltage (hangs up and so when high load) and i had to reset it to 1,8V and now its fine again at 1,44V max.

All this meaning that never thrust the BIOS readings in vcore

'lo all.

i just recently received this motherboard, which has replaced my GA-P965.

i've had great results with overclocking my same cpu on this motherboard (considering
the P965 didn't exactly support the Q9 series).

unfortunately, i seem to have hit a pretty bad wall that i can't seem to get past.

cpu is Q9650. vid 1.1625. e0 stepping, i believe.

i cannot get anything higher than 420fsb.
even at 421fsb, my system will fail to complete posting -- it will get to the splash screen then lock up halfway through "memory available".

at first, i thought it was my memory. so used the divider to get it as low as possible but the same thing happens. tried upping fsb, nb, vdimm voltages up a notch and nothing helped. i tried dropping my multiplier to 7 and seeing if it's my CPU not being able to handle 421 (as opposed to 420, right?) but that didn't change anything either.

i have twin2x4096-6400C5's. 800-5-5-5-15/18 rated for 1.9v.

then i thought there was maybe a wall but reading everyone else getting more than 450FSB makes me believe that there has to be something else wrong somewhere.

any one have any tips?

also running bios F9b.
there's a C on gigabyte's website and a D on gigabyte's beta ftp but i'd like to avoid flashing until the very end.

thanks.

edit::
forgot to mention that my bios vcore is set to 1.25 (or somewhere around) and cpu-z is ~1.248 for idle or load -- i've pencil modded the vdroop so it wasn't so bad (i used to have it set to 1.275 and have it drop to 1.216 under full load).

c1e and all those options disabled.
memory timings on auto (5-5-5-18) @ 2.0 multiplier (840)

420x9 runs prime95/occt/memtest stable over 10+ hours.

but as soon as i hit 421, it fails to complete booting.

edit2::
also, i've tried a single stick from this kit. 2 other kits of the same model and a 2gb kit of the same line.

I tried Searching but no luck. I'm trying to find out if our boards can handle DDR2 PC9600 1,200MHz memory or faster?

I Want to pick up some new ram but think I wont be able to use it to it's full potential.

You just need more voltage somewhere. It's hard to tell if more is needed for the chip, for the MCH/FSB, or for the DDR2, but just try increasing the voltage in small increments on each of those pieces to see if it helps.

Yes, 1200mhz memory will work fine. But like most other boards, it will automatically set the memory to run at 800mhz until you tell it to run at a higher speed.
post #3796 of 4644
Well, I managed a painless 4ghz overclock on my E8400. Unfortunately I cant seem to get prime95 stable at 4.14ghz and no amount of vore or DDR2 voltage seems to get me into Windows at 4.2ghz. Temps are below 50°C. Oh well, 4ghz was my target!

If anyone has any ideas of how to get to 4.2ghz, let me know.

System specs:

E8400 w/ Akasa AK-965 HSF
P35-DS3R
2x2gb Corsair XMS2 DDR2-800 CL5 1.9v
Gigabyte Radeon 4850 w/ Zalman 2-slot HSF
600w PSU and an Asus case with 3x80mm fans.

What's the max voltage you used to try to get 4.14ghz stable? And what FSB speed were you using? And what MCH/FSB voltages?
post #3798 of 4644
The max I tried was:

CPU voltage 1.4v (CpuZ confirms)
DDR2 voltage was +0.3v (am guessing this took it to 2.1v)
Everything else was +0.1v

At 4.14ghz, the FSB will have been 460mhz (ie. 4140mhz/9 = 460mhz)
post #3799 of 4644

Might need more voltage on the FSB/MCH then... 460mhz is about where I bumped it up to +.1v, but every board is different, and yours might need more.

Also, since you only have DDR2-800mhz, your ram might be limited you as well. Some ram just won't go higher in speed regardless of how much voltage you give it. You're already overclocking it +120mhz at 460FSB, so I wouldn't be surprised if that was your wall.

hello All,

I have this motherboard with CPU E5200 and OC 4.0GHz, but is not stable in ortos, is necessary more voltage on FSB/MHC too? what is the high secure voltage for my CPU? here my settings:

- E5200@4.0GHz (320x12.5)
- CPU voltage 4.5v
- Corsair DDR2-800 (5-5-5-18)

P.D: sorry for my english.

Saludos,
My System
