I'm liking these settings. Once I get all the v settings as low as possible from here, I'll stability check with high priorit for a longer time.

For me, GTLs manually set made all the difference here at this 8.5 miltiplier. With 9x and lower fsb, auto was better. I didn't go too high fsb with 9x though.

What GTL's did you use?

[mrcape]

for that I used 59/59/59

now I'm using 58/58/58/ with lower 1.13vtt and 1.29nb reading in everest.

At this same clock using gtl auto it would crash instantly even with more vcore, vtt, nb, etc.

[turtletrax]

Nice work mrcape

[mrcape]

I'm siked to be getting close to 24/7 with this one. This chip is so much better than my other, it's just ridiculous.

Here's the same clock with lower nb and vtt, priority 9 blend 2hrs...



Still with 1.13vtt and 1.32nb I used 59/59/59 gtls. Any lower and I bottomed out, for example, crashed orthos in about 20min at 57/57/57 with those same voltage settings. 59 seems to be the sweet spot for these settings / my setup.

Edit - I'm using Bios 01/09

Greetings to all! Forgive for my bad English. Somebody removed Al radiators from voltage regulators in this board. The following, who the manufacturer and what for marks on them interests?

[georgesod]

Can somebody tell me how is the vdrop with 8x00 cpus?

[Praz]

Since it seems users are determined to use GTL settings that work for others, when posting those settings the BIOS version is also needed. The CPU GTL voltage at a given GTL value will be different depending on the BIOS version being used. The major influence of correct NB GTL will be board dependent and when using a dual-core CPU one of the CPU GTL settings will be processor dependent.

[Mav451]

Is that table found on edgeofstability applicable to 45nm? I'm wondering cuz the lowest VTT value looks to be standard for 65nm, not 45nm.

Depends what is meant by applicable. If a BIOS version is used without auto switching tables the charts are still accurate as to what voltage is being set for a given GTL value. But the target point for the primary CPU GTL needs to be held around the 63% mark not the 67% indicated in the table.

Though not 100% pertaining to this board, a new memtest+ was finally released. 2.00. Has many bug fixes and support for new chipsets etc. This version displays the chipset, clocks, ratio and timings properly on my DFI board. If anyone is stability testing their memory on this board, use this new version

http://www.memtest.org/#downiso

Now, if only DFI could incorporate this into their BIOS like they did on their older boards. I really miss being able to run Memtest right from the bios on my NF4 board.

I just flashed over to 0109 from 11/07 and it seemed like the flash went alright (although it took a loooong time to finish). I used my floppy drive for flashing duties. Anyway after the flash I'm now getting some weird corruption within my "Voltages" tab in BIOS. Pretty much everything looks good, I've got the new lower "VTT" options but below that the settings are all messed up, can't even read them? It starts below the "Vroop Setting" and ends where you can either enable or disable the GTL's? I would take a picture but my camera battery just died earlier today. If you have this problem it would be very obvious to you because there is no way to properly read those options or set them? Please let me know ASAP because its got me nervous!

I agree fully. That was awesome

This is what you are seeing, right? If so, it's fine.

Like this? It's not really a problem, the settings can still be accessed if needed and will be fixed in the next BIOS release.

The two option in order are:

GTL+ Buffer Strength
Strong
Weak

Host Slew Rate
Strong
Weak

Very seldom is it necessary to adjust either.

[Roger_D25]

Phewww, that is exactly what I'm seeing! First of all thank you both very much for taking them to post that picture and for cutting my stress levels (in hindsight I didn't do a very good job articulating my issue so I'm glad you were able to read between the lines). With that said when setting the option right above "GTL REF Voltage Control" what do you choose? I can't make heads or tails of the two available settings (I assume one is enable and one is disable but not sure which is which)? I have the same problem with "GTL + Buffers Strength" as the options are not very clear? Thanks again very much!

[gfourth]

You can thank Praz, I got that pic off of one of his posts at DFI forum.

[Roger_D25]

Thanks Praz, your a big help around here and its greatly apprecaited!

[Praz]

I know it's not much but I try to help where I can. About the only reason I hang around here really.

[Roger_D25]

I'll do my best to keep you sticking around by asking lots and lots of questions then, lol!

Hey guys,

Wanted to run something past you, thats makeing my life a bit difficult with this board.

OK, as I posted a page or 2 back, I have 4ghz 12hrs prime stable at 1.32v. Ive also run memtest overnight, to check my memory settings are ok.

However, sometimes when switch on my PC it freezes on the windows loading screen for no apparent reason. I have to restart a few times, and sometimes even that doesnt work. In which case I have to clear cmos and manually set all my individual settings. It seems cmos reloaded doesnt even allow it to boot (its like its not applying the settings correctly).

Once ive manually re-entered the settings, it boots fine, and runs windows. Ive even primed it again to make sure.

Its really quite frustrating, and it also makes it hard to push the chip further, cos your not sure if windows is freezing because of a bad overclock or not.

Im on 0109 bios, so maybe its a BETA bios issue? Any thoughts?

[kberguy1]

Now that I have my new Q6600 G0 sorted out, I want to maximize the rest of my system. Because of the mostly favorable reviews, I have ordered two new Asus HD3870X2 video cards. Initially, I will be testing just one card, but once the CrossFire drivers are released, I will run them in that mode. For those interested, the Asus and HIS versions of these cards are factory overclocked from a core speed of 775 MHz to 825 MHz.

Based on my experience with the HD2900XT, I believe the drivers for the HD3870X2's will mature quickly, and they will end up performing very well together in CrossFire mode. I sure hope so, as these cards are $495 CAD each.

If these were single GPU HD3870 video cards, I wouldn't worry about a performance "hit" from using a P35 based motherboard, but I am concerned putting two GPU's worth of video card through one PCI-E 8x slot is going to create a bottleneck.

Ultimately, my question is this: "I know the X38 based motherboards with dual PCI-E 16x slots will be a better choice for maximizing the performance of dual HD3870X2 video cards, but will the performance gain there be offset by poorer CPU overclocking performance?"

I believe it is a 16x/4x PCIE config with the P35 chipset, so I think you will be limited by the 4x on the second slot.

In that case X38/X48 would be the way to go, which shouldn't hinder CPU overclocking performance. If anything it should be better

[mad_skills]

X38 chipset has somewhat better memory communication than the P35. CPU wise, it isn't that much better.

It happened to me as well. My workaround was boot through windows using optimized defaults. then restart and reload my overclocked settings.

It happend when my system crashed after trying to lower the voltage of my overclock. hehehe
