Gigabyte GA-P35-DS3L Thread

[TriBeCa]

I don't know what options you have in your BIOS, but mine goes up in ~0.25v steps. I needed to increase two steps to get to 3.2GHz on this chip, and 1 step at around 3GHz. Mind that's on an 8x multi.

my experience has been that if you're pushing the FSB up and several vcore increases show no noticeable effect, an increase to the MCH voltage will usually do the trick. remember that if a voltage increase gets you from crashin the moment you run prime95 to crashing 5 minutes after you run prime95, you've probably found the component that needs more voltage - so give it a little more.

Got my IFX on the NB today. Here are some pics. Gonna play with the overclock some more tomorrow. It turned out to be a really tight fit. I had to rotate my CPU cooler 90 degrees to let it squeeze in there. It turned out really close to the GFX card also. Seems to be working well so far though.

I'm confused...where's your PSU?

My PC back in it's glory days but you can see the orientation of the case.

maybe MCH voltage? I dunno, I don't have this board yet

But it might not be helping that you have vdimm overvoltage set - by my count your RAM is hugely underclocked, so it shouldn't need extra voltage.

Wow, I completely missed that... my bad.

Well, first we should find out if the problem is motherboard related or processor related. You said it boots up at 266x11 for 2.9ghz. Try 290x10, 322x9 and 362x8, and post back with whether those also boot successfully or not. If they all boot up successfully, I don't see how we can blame anything but the processor as just not being a great OCer.

there the link too my cpu-z validing

like too know if i can lower my ram timeing at 5/5/5/12 atm but i have never mess around with over clocking ram its says i am at 400 mhz but the ram can do 800 mhz she ran stabel for 2 days no blue screens of death and no reboots
so i am stabel i just love a little help too up my ram speed

[Unknownm]

well I'm 3ghz.

375fsb x 8 and it's 1500mhz Rated FSB

Your RAM's running at 800 MHz. Remember it's DDR 2, so you double the FSB to get your RAM speed at 1:1. Try tightening your RAM timings and see how it tests.

E6750 @ 3.6 ghz with the 1.46785 voltage in the Bios. +.1 MHC, +.1 FSB, +.2 RAM (G.Skill ddr2 800mhz blue ram[oc'd to 900mhz 5-5-5-15]).
For the 6750 to run at 3.6 ghz the FSB has to be set at 450 mhz.

Hey Guys,

I will probably create a new thread for this, but it pertains solely to this board, so I wanted to post this here first:

There is a known issue with the P35-DS3L that several boards will reboot upon OC settings being applied in the BIOS. Namely, unlocking the FSB option causes the system to reboot right after the POST screen with all FSB and memory settings returned to default (locked FSB, auto memory timings and multiplier).

I had been held prisoner at stock speeds by this problem for several months after being able to overclock my first week with this board up to 3.2GHz. I was very pleased until this occurred, and today I did some more research on the topic. Several "solutions" have been mentioned, and here are several I have seen:

1) Set Halt on Errors to None
2) Disable serial and parallel ports
3) Clear CMOS, etc.
4) Bad PSU
5) Bad voltage/memory timing settings

However, I had tried all this without any success. BUT, my problem was solved from an unexpected source! An external USB hard drive seemed to be the problem. I'm not sure the root cause of this, but upon unplugging this, the system boots up properly with any overclock settings I've tried! Thinking back to it, I had this HDD disconnected when building my system, and the problem could've very well began when I connected it. The drive is a Western Digital 250GB MyBook if you're curious.

So, any of you DS3L'ers out there stuck at stock speeds, yank out any USB legacy devices you have connected to see if that solves your booting issue! In my situation, I was 100% the hardware was fine because 1) I had overclocked through the BIOS before, and 2) I had overclocked successfully through software even with this boot issue. I still have several USB devices connected, so perhaps hard drives are the main culprit.

I'm currently at 3.0GHz and look forward to shooting for 3.6. Look forward to updating my OC settings on the front page Sgt. Spike
