**Gigabyte GA-X58A-UD7 OC-Tips-Bios-Discussion Thread**

[Sam_oslo]

Good job.
Those few degrees is all we chaise after, and gives the little extra (mentally and practically) that one really needs to hit 4.5GHZ.

New BIOS didn't change much, it seams. Any change log?

[LarsMarkelson]

So I've got 4.3ghz HT On just about 24/7 stable now with 1.344vcore, which is a bit high, but my VTT is relatively low at 1.24v.

Anyone know if raising my VTT will allow me to get 4.3 stable with less vcore on the CPU?

[sRHunt3r]

I think it depends on your cpu, mine requires 1.325vcore and 1.355vtt to reach 4.4 with ht on where as sam's requires less. I would say try it, it can't hurt and may lower your temps enough for you to clock higher.

If the UD7 uses LESS voltage than UD4P then I'm laughing!

Hey Bex, good job. That's the same Vcore as my 219x21, SuperPi32M, but I was hoping to get it prime stable with that Vcore , of course it didn't work , yet ... .

The MB plays a role too, but I believe the CPU batch# plays a much bigger role in how much vcore one needs.

Doing some more testing for 24/7 settings. Ran linx then a long blend run last night, now testing custom blend, set 4200mb mem to test for a couple hours. If it passes I will leave it like this.

[LarsMarkelson]

Man those temps are good. Are you still using the AC to cool your rad?

Btw, we have the exact same chip. Except mine is the Xeon W3520 version... 3945A906 right?

I've only done a bit of overclocking for now and have a lot more to go, but right now I'm sitting at 206x21 = 4326 mhz / HT on @ 1.344v load, 1.28v vtt I believe. I forget the exact other settings, but they are very close to stock. CPU PLL is undervolted at 1.4v IIRC. I wouldn't call this a 24/7 stable overclock yet as I haven't really stress tested it, but it's been working great for normal everyday usage.

Yes ac is on, I ran earlier with no ac using the same settings and topped out at around 75c.
Batches are very close, I have 3945A936.
I'm still learning the board but getting better with it.

Great chip Tom

[emertX]

Can you get any higher PCIe-Clock with the UD7 than with the extreme?
That is mine! Due to PCIe-Clock limitation I can't get higher clocks!





Also primestable is 226x19 but no picture at the moment!
I need to know if it's worth it to buy the UD7?

[zalbard]

Your results are already great, doubt they'd improve much, it's not as much motherboard related as you might think.

[OC Nub]

Great chip Tom

Thank you.

[Sam_oslo]

@OC Nub
That's good results, and really good temp with that Vcore.

1.24v is very low Vcore for 4.4GHZ and you CPU seams to have more OC headroom. You would probably hit 4.5GHZ with this MB.

[Sniper]

@EmertX

You will get higher bclk on the UD7 ws an unmodded Extreme due to higher PCIe.

[LarsMarkelson]

Wow EmertX, very nice chip. What cooling are you using?

Also, do you know batch number?

You have seen the second picture, haven't you?!

The famous 935---cooling is a MoRa with a HK 3.0 LT---you guys know a MoRa?


So I already got the 4,6GHz but I'd love to bench the 4,8 and stabilize the 4,7 or so!
The onliest way I can go is the hardmod you guys think?

EX58-*** or most older X58 boards will not break 222bclk w/o doing the hardmord so you get more control over the PCIe bus speed.

The X58A-UD7 seems to top out @ 237blck from what I seen so far from mine and a few others testing.

[OC Nub]

Picked up another 260 to try sli on this board, having a lot of fun now playing with the rig.

Yep I've seen that. Good job and bold attemp. You may have a better chance to get that Primestable on this MB.


I haven't seen your primestable 226x19 yet. Where is it, can I have a look at that beauty?
222x19 Primestable is the highest I could get with 19x. I've had a few short prime-run with higher BCLK, but those doesn't count as primestable in my book.

Just don't forget to disable PhysX.

[OC Nub]

Just don't forget to disable PhysX.

What fun would that be?

I have a pair of 5870's that score much higher but the random stripes, and freezes have pissed me off enough to send me back to green for a while. When something fixes this issue I will gladly go back.
These card are fun to play with and are plenty for anything I do, until I find a game I enjoy playing again.

[Sam_oslo]

That's were close to 3DMarks P26259 (PhysX:enable) on my GTX 295 @650/1200/1402 .
But I haven't played with 3D lately, just waiting to see more about GF100 Fermi before jumping on a new GPU.

[sRHunt3r]

Nice 3DMark Vantage scores ...... I wish I could enable physics on my card but the games I play most do not utilize it anyway

Here is mine @4.4 with a single ATI5870 P21041 I noticed that Vantage does not correctly identify the multiplier as 21 but shows my cpu @ 4.2 with the correct bus speed of 210.
