guys i have a question regarding memory in general with this board some people say that it is also undervolted by about 0.2v...
so does it mean that Radaja who posted his template where the RAM runs at 2.2v in reality only runs at 2v

Hi , Im new here this is gonna be my favorite thread

If your board undervolts vdimm its going to be 0.02 not 0.2.

I OC'd my E8400 to 3.91, but it reboots & crashes if I try to get it to 4.0GHz.
What can I plugin or change in the BIOS to get it to boot and run stable @>4.0GHz?
It was orthos stable (@3.91 for about 1/2 hour) before I canceled the stress test, I'd rather get it over the 4.0 barrier first and then stress it overnight.

Thanks

Does anyone have issues with the UD3R/P waking up from sleep mode when running 500FSB...at 467FSB no issue...now at 500FSB my computer goes constant reboot cycles when I wake up from sleep mode.

I heard that someone had a similar issue when returning to windows after sleep, somone asnwered it was because of Windows 7. I doubt it... It was ion overclock.net in the EP45-UD3P Official Thread

[truehighroller]

I have an issue with it waking up as well but, to be honest I've never had a motherboard do it correctly so I just turn it off.

[andressergio]

guys a quick question...a month ago i installed a dedicated 9800GT ECO for PhysX my main card its a GTX285, now i realize that maybe both are working on x8 Speed at PCIE ?

i dont know if i did wrong, games with PhysX run amazing rest i dont see dif but on 3DM06 scores are lower now...

Cheers !
Sergio

[gergregg]

Sergio,

That is correct. With two cards installed on a P45 chipset board they are both running at 8X, but there shouldn't be a big hit in performance though.

Try bumping your MCH a little. If that does not work, then use more vcore and term.

Thanks NoGuru...I got 4.0, and as long as I know the voltages are ok, I'll stress test it... prime95 (small ffts)/12 hours and memtest86+....

I just posted at OC before I saw this.....

thanks mate i benched 3DM06 with one and gives more than with 2 installed...but on games i dont really see that dif

thanks again

Does anyone have issues with the UD3R/P waking up from sleep mode when running 500FSB...at 467FSB no issue...now at 500FSB my computer goes constant reboot cycles when I wake up from sleep mode.

I used to be at 4.25ghz with 8.5x500, I went back to 4ghz 8x500 (back to air cooling) and could lower the voltage just a little bit, I think 0.25V or something and since then sleep has been working. Not sure which made sleep working again, lower multiplier or lower voltage, but having sleep working is actually quite nice.

Getting ready to build a new 1156 rig, and will be selling the E8400, Memory and board. Will be posted in the For Sale section in a week or so.

[Hoss331]

Some early testing with dice, 5147mhz

[In-Fluence]

Hahaaa, I noticed my positions went down in the HWbot rankings - good work buddy!

[radaja]

guys i have a question regarding memory in general with this board some people say that it is also undervolted by about 0.2v...
so does it mean that Radaja who posted his template where the RAM runs at 2.2v in reality only runs at 2v

yea when i gave mine 2.20v in bios my board would produce 2.18v in windows under load.
with my cellshocks id give it 2.14v in bios for DDR2-1200 and get 2.12v in windows under load

[Hoss331]

When you want them back have at it, im sure the team can use the points.

Yallo all,

For as long as the Core architecture has been around, I'm still really a noob for tuning reference/GTLs. I need some help getting stable at at least 4.2 (I'm trying to hit 4.4, I should be able to make that,no?). I've made it to 4.2, but after ~8 passes, I get a BSOD in w7. I can fill in one of those profiles to let you know what my settings are now a bit later - let me know if you need to know anything else. Are there any good guides on how to tune reference voltages or GTLs? Just trying to figure this out...

Post your template, vid and current temps.

[DTV DRAGON]

hey Iam hopeing someone can clarify this for me, rith now i have me cpu o/ed to 4.0,445x9
my new ram i have is 1600 mhz and now i have it running at 1424 , I have my freq latch at 333 and the system mem multiplier at 320b, now i want to get my ram up at least 1600 ,so when i set the sys mem multiplier to 400b it goes to 1780 mhz wich is way to high,I tried and it wont boot at that setting, so my question is how do i raise my ram to get it close to1600? I was wthinking about this my cpu multplier is at 9 right now, what if i cheange it to 8 and then it will be 445x8 3.56, and then i can raise my fsb to 500 so 500x8=4.0 does that make sense? am i loseing any performance by dropping cpu multiplier to an 8? and then in turn by raising my fsb it will be raising my ram mhz...correct? sorry i hope you guys can understand all this lol

[MarcusFoX]

Don't wanna jump on the bandwagon but I agree with hoss, they're a little high for 24/7. VTT of 1.46 is about the absolute limit imo, but wouldn't want to run that 24/7, and vcore should be ~1.45 max with real good cooling, ideally h2o or better. I assume your CPU/NB skews and GTLs are not tuned? If so you could probably save a few volts if you tried tuning those. Otherwise I would back down a bit mate or your CPU could suffer.

were do you find gtl's on this board I dont see those in bios I know the M2f has them??? and I have a look at the skew chart for this board ive got everything set to my fsb voltage.

I dont think there much else to tweak...

[Hoss331]

The references are the GTLs on this board, cpu and mch. What skews are you using?

[In-Fluence]

Sorry, my fault - the GTLs on the UD3P are just one setting called 'CPU reference', this changes with your termination voltage (VTT). By default, your CPU ref is 0.76 when VTT is also at default of 1.2v. For me, increasing CPU ref to 0.785 then increasing the VTT often gave best results, but occasionally needed to go up or down one on the CPU ref to get stable. This is different for everyone's configuration, but should still be around that region (i.e. one or two up or down from default). As for skews, increasing them as you increase FSB can yield better results at higher than ~475 FSB, seems even more crucial for benching at 530+ FSB. I found CPU being 50ps less than NB skew often gave better stability , but sometimes equal values worked better.
