@ Jsunn

Set your Vtt to stock 1.2 then lower that MCH Ref to .68-.70 then raise your Vtt back to where you had it.

Then you will see .68-.70 in EasyTune instead of .76 which is the default %

Can you reupload it? It's not working at the moment

Should work now.

Any updates for the EP45T UD3P Nelly ?

[Crazymilk]

I have just purchased the Gigabyte GA-EP45T-UD3R DDR3 version to run on my QX9650 with Corsair 1800Mhz RAM.

Have been using the Asus Maximus Extreme that has been a hunk of crap with my QX so fingers crossed this Gigabyte thingy will be much better.

I will try to get some results once I get my NB water block.. (which are like Gold dust for these boards btw and had to order one all the way from Germany

I have always used ASUS mobos b4 so Im sure it will be a nice learning curve or me.

I notice alot of people using the 'easy tune' utility on this thread. Is that what most people are using to OC rather than the BIOS or is it just to show volts etc etc???

@ radaja

Oh Man this is really sick and Crass simultaneously with an air conditioning to cool

[Jsunn]

Thanks for all of the help. The problem I was having is that I dont' know what depends on what with all of the different BIOS settings. I have read through this thread a number of times but I am still a bit overwhelmed.

Thanks for the help.

Yep all the references depend on other settings and change if you change other settings.

Like Dram voltage changes all of the memory references to 1/2 of the Dram voltage if left on auto.

The Cpu ref and MCH ref depend on the VTT, so like said above if you set the ref's with VTT at stock 1.2 then change the VTT ET6 will still show them as the same(as they would be with 1.2 VTT) even though they are altered

@pangingIII ,Thanks so much about yr recommended ,I haven't not much OC RAM exprience, just wana hear some opnion , I search all around about my ram Ocing and found
no info, 550 MHZ 1:1 I can boot up but not stabil with memtest or orthos even PL 11 and auto subtimming ,I 'll try later, anyway yr step to checking RAM stabil is so great appreciate!
so far I can go 538 MHZ 1:1

[pangingIII]

Thanks, it's looking a bit better now. I'm currently set on Turbo with a tRFC=54, PL=8, TRD=8
Still not the best bandwidth though.

you may want to first save the existing configured CMOS to a profile in BIOS or save it as file in a USB pen drive.

and try this next, change tRD value in bios on both Ch A and B setting from 8 to 7, and see if you can still booting to bios and then into Windows?
if you can, then retest for ram and overall stability again.


in the case that you like to tweak your memory timing in Windows and then take the values setting into BIOS,
here's an example of the memory timing values in Bios vs. Memset (or in Everest's Motherboard > Chipset)

as far as i can see, it's just like the owner of Memset program used to explain somewhere around these forum.

20-8 = 12
13-8 = 5

the tRTP value in BIOS is seems to always has the value with +2 in Windows.

this's the exactly memory timing values that i set in bios...

5-5-5-15 / (in the Advanced section) 5-5-12-70-5 / tRD 7 on both Ch A and B.




please also note that, you have a different hardware than mine, so you may want to disregard my voltage setting values that you see in ET6.

[valtopps]

anything you see im doing wrong please let me know. oc 3.6ghz. if i try 3.8ghz with 1.4v blue screen, i really want to get 3.8-4.0ghz on my q9550e0

i don' know about other people, but for myself, i always included ET6's voltage page when i take screenshot, it's mostly for my own voltage setting records. and it might be useful to mke them visible to other.

i use ET6 (to replace SetFSB) sometimes, like when i want to get above 600fsb in Windows or when i want to see how far a ram kit can overclock, i only use ET6 for something like this.

Any updates for the EP45T UD3P Nelly ?

Note: This is for the DDR3 Motherboard.

On Tweaktown theirs F4a, so not sure if this is a newer version?

[Supershanks]

Great thread guys
Just getting going on the GA-EP45-UD3R
Am running on air at the moment and have been suprised by
the low CPU temps Any one else noticed this?

[Jsunn]

Well, I seemed to have corrupted my registry from the multiple BSOD that I was getting trying to O/C. I had to reinstall Windows last night.

Going to try again tonight.

What BIOS version you using m8? I have just got that mobo as well and gunna start soon.

[Lsdmeasap]

Shoulda used system restore by booting from the dvd and then choosing repair my Computer, then system restore.

Good luck man!

[Supershanks]

Have you tried booting at stock or lower OC. It's not unusual to get lost user or can't find registry messages, which thankfully go away when oc is lowered.

Hi Lsdmeasap how you doing not seen you over here much until I clocked this thread

[Lsdmeasap]

Ahh I'm aight! How bout you? I tend to mostly checkout this and the Water section, but I been here a good while now

Fine ta Just gradually getting my stuff together to try i7 920 , but enjoying this board in the meantime.

You're welcome. hope you get to the point that you prefer to.

[pangingIII]

my trfc is set to auto and its setting my memory at 68,with my 8gigs.in everest im scoring 11000's in write and copy but only 9958 in read. would dropping trfc down to about 55 improve the read score?i know i should just try it, but i have to go to work,was just hoping someone had the answer. thanks

sorry i really don't want to sound like i know a lot, because i'm not. but don't judge your 8GB ram system overclock with Everest's score, you can't compare the read score with 2x1GB that can run a low tRFC like 25-30. may be you may want to use other tool like a SuperPi 32MB run and compare it with your previous overclock.

[radaja]

trust me you know quite alot,i was just frustated that i was getting 11000w/write/copy and just falling short of 10000/read(always 9950. but i tried lowering trfc to 55 and got it to 10000.

[Jor3lBR]

Anyone know how to solve the problem between the Strap 2:40 and MCH Volt above 1.440? I really like this strap but to not be able to raise the MCH voltage is just a pain.

[Jor3lBR]

Finally started to play with this board again but can't find anything on the volts measuring points, wanna take multimeter reading to calculate the references %.

Anyone wanna share this info? Maybe older Gigabyte boards share the same spots for vcore, vmch, vdimm etc?
