Gigabyte GA-P35-DS3L Thread

[Mister Nobody]

Thought I'd post an update on my OC'ing experience...

Using BIOS F8a, I set my FSB down to 389 instead of 400, so at 9x this gives me 3.5 GHz. PCI-E set to 100. Memory timings are now 5-6-6-18. The other timings are left on auto. I set voltages to manual and added +0.3v to RAM. Then went back and set voltages to auto (the +0.3 will still show and stay set there). The reason I set voltages to auto is that I still cannot make any change to my VCore - if I do I cannot get past POST stage...still can't figure out why.

Looks like I can at least run 3.5GHz stable...I ran Orthos blend for 12 hours with no errors or warnings. Temps are good, CPU peaked at about 44 but mostly hovered around 42/43.

Other than not being able to change the VCore, it looks like my RAM sucks. It is rated to run at 400 FSB but it just can't make it past 389. I'm happy that I can at least get an extra 500 MHz but with my cooling and better RAM I'm sure 4.00 GHz would be easy (if I could only figure out how to change VCore and still boot). I may trade my OCZ in and get some G-Skill 1000 sticks.

Any last ideas why I can't mess with VCore and have any success booting?

So I recently sld my 680i board and ordered a DS3L. Just curious about al the Vdroop on the Vcore that people have been posting about.

I've had this chip in an Evga 680i, P5N-32 680i, and a P5K-Deluxe Wifi. I've recently decided to step my PC down from gaming to just wanting to have the most processing power I can squeeze out of it.

With this chip I saw these best results on the P35 chipset, which was 3.825MHz at 1.45Vcore. Thi was under a high end water setup btw, but I am in the process of picking out some new cooling and am expecting similar results with this board.

So I'm wondering what people are seeing with this board on G0s and at what Vcores with what Vdroops. I'm gonna be sad if I can't get my G0 back up there.

Thanks for the help and I'll post some results of my own after the board gets here tomorrow.

ok, why is cpu-z saying my coreV is lower than what i set it for in bios? am i missing something?

Yes, all 136 pages of this thread.


<<<POST COUNT!!!

This board is noted for both a significant vdrop and vdroop. As noted, there are plenty of references to this throughout the thread (I realize 136 pages is daunting though).

k, so i should go by the cpu-z reading and not what my mobo is set for. also is there a fix for this?

Greetings thread readers/responders,

From this point forward, instead of posting your best overclock results here in the thread, please PM me (click on my name --> "send a private message") to get your name added to the list of successful overclocks in the OP. Please remember to send ALL of the necessary information, and check the first post if you do not know what all that includes. It'll be much easier for me to keep track of who's been updated or put in the list that way.

I'd also like to include a list of general tips regarding overclocking this board (such as the vdroop problems) in the first post as well. I'd like all your input as to what all to include in this tips section, with the goal of eliminating many of the redundant questions that keep getting asked, as well as having enough of a guide for new overclockers to work with on this board. Please give me ideas/tips for what all to include in this tips list/guide. The format will likely follow something like what is shown below...

OVERCLOCKING GUIDE:
Step 1: Do this
Step 2: Do that
Step 3: Check this
etc...

GENERAL TIPS:
Vdroop/drop: Blah bleh blah.
etc...

I'm going to go ahead and get started on an OC guide and a FAQ section.

If anyone would like to repost some of their earlier instructions or add a topic for the FAQ section please PM me and I will be sure to include it in the compilation.

I run at BIOS 1.55, which is Idle 1.505 (there's your vdroop and vcore) for 400x9 = 3.6ghz stable. I could probably do better if I knew what the normal FSB and Northbridge voltages were, but I havent' been industrious enough to check them yet.

You may have to loosen up the timings on the memory to get it to run at that speed. Ctrl-f1 unlocks this menu.

Are you sure you're setting the Vcore properly? What I mean is, when you change the vcore in BIOS, the setting is usually higher than the true idle vcore. I would suggest actually lowering the FSB until you can get your manually set VCORE stable and test the difference between BIOS and Idle VCORE in Windows to really get an idea of what it's being set at.

My bios is approximately 0.045v higher than the true measurement (idle). So, I set 1.550 for 1.505 Vcore Idle and 1.375 for 1.325 Vcore Idle. (or whatever the closest may be allowed in BIOS).
