Up FSb term to eg 1.36 and test again, if no go remove 2 dimms and try again... are we talking Vista ? but I suspect reference volts that are wrong and maybe to tight ram settings ( eg TRFC )

But I would start from zero so a plain default setting and slowly up the FSB to eg 400FSB... then test how your board reacts to lowering FSB term voltage,etc... see how low you can go... FSB term 1.26 MCH 1.3 and co should be okay for up to 500FSB... CPU PLL works here at 1.4 set in bios...

It's nice to post templates but if you are not aware why it would work with setting 2 and not with your seting will not get you anywhere. Learn the board, learn how she responds...

@ezaleina I see MCH Reference in your setting still be 0.76 ...may this is your problem. try to reduce it to around 0.70- 0.68 may help alot

[ezaleina]

@1nsane @Leeghoofd @Bugjae
thanks for your guide.,i will try it..

[ezaleina]

now i'm successfully boot at 4ghz with 1.36v.,.,but when i run super PI 32mb.,it fail and got message 'Not Exact In Round'.,do amyone know what is that mean..?

[AAdjuster]

I was thinking of ordering this mb today. Gigabyte GA-EP45-UD3R

I have been reading this thread, and I was wondering if this is a good mb.

[yomny]

hello guys i've been reading a lot here and i need some help, i know its christmas eve but a helping hand whenever you are able to will be mostly apreciated. Im trying to run 360x9, i cant get it to window with 1.44 vcore under load, I have all settings to default manually set...except MCH which is at 1.36v. I would like to know when do i need to increase MCH reference or all the reference voltages by that mean. I can run some PI 1mb calculations in about 13 secs.. i just cant run prime small's for more than a few. secs

[yomny]

sorry for the double post.. just some info here i can run 2.9 with only bumping the vcore to 1.42 (w/o LLC 1.36 under load) and leaving everything else on auto... running my ram 1:1 which at that FSB it runs it at 667 or so. I also tried to run a bit higher FSB and increasing vcore and MCH but no luck, still cant run prime small. Im guessing it has to be another setting besides the MCH or the vcore. thanks a million for any input you could type in.

[nugzo]

First problem I encountered guys, hope there is a solution for this.

Any MCH Core above 1.460v will cause the mobo to not post or cycle boot and give red OC error.

Even in stock settings this will also happen.

I tried to look around but I confess I'm tired and can't see to find any solution.

Help!

Thats Strange. I run up to 1.7 MCH with no issues. Stock MCH cooling w/ Arctic Ceram.

[BuGjAE]

@yomny If you have Core2 Duo 45 nm make MCH reference to 0.70 or below that 'll help you for basic setting

[yomny]

im using a q6600 65nm, check out my sig. Im just having trouble running prime.. at 333 fsb right now. I need some help with the reference, pll, vtt volts. thanks

Its means that your CPU isnt stable.

[yomny]

what i've read and have been advised is to bump the MCH up a bit.

For ur RAM just under clock it (800MHz 5-5-5-15 for example) until u can get it running Prime good, then fix it up.

Help!

does it do that at any fsb:ram ?

was it doing that from the beginning ?

Hello

Excuse my english.

I nedd Know if someone of thi kits of memory is compatible with this motherboard -EP45-UD3R / EP45-UD3P- (if someone of thi kits of memory is ok to work with this motherboard.

I´m in problems because i must buy one of this kits.

GeIL DIMM 4 GB DDR2-1066 Kit (GB24GB8500C5DC, Black Dragon Series)

GeIL 4GB (2GBX2- SKU#GX24GB8500C5UDC ) Dual Channel Kit

http://www.geil.com.tw/products/showSpec/id/70

Thanks

If both are good with this motherboard can you tell me what is the best and the stable-consistent of thi two kit?

[PolRoger]

I've been planning to run this chip at 500x9. I'm using the 333 latch and 2.40B divider.

It took a couple of days adjusting and tweaking MCH/VTT and GTL refs to get the voltages down and everthing stable for a nice 24/7 type setting.

Testing with Prime custom FFT 1024K to 4096K. Using 4 sticks HyperX PC2-9200. Cooling is with a TRUE and one Sanyo-Denki. Loadline is enabled.

[Jor3lBR]

Yes before I installed the OS I noticed that I was copying the templates from you guys and every single template I used was giving a blank boot screen. Tried everything, diferent ram slot, ram, vid card, voltages, straps nada...

So I decided to adjust the options individually until I found the problem was only in the MCH Core Voltage, I left it on 1.440v and used it till today I was hoping to be a problem that could be solved with bios update or using ET6 but is still there.

I have to RMA then

Whats crazy is you being able to hit 556fsb with a quad and only 1.44 MCH. I may have missed it. What cooling are you using on MCH?

Nice Work, I found on mine w/ E8400 that .66 MCH ref was the best, but I RMA'd my board since I think the chokes were making a high pitch'd noise(ones near mem slots and other side of CPU by Mosfet)

[BuGjAE]

@APC
I use this ------->GeIL 4GB (2GBX2- SKU#GX24GB8500C5UDC ) Dual Channel Kit
It stable @533 Mhz speed and cannot hit stable even 540Mhz. So, if u need to go over I reccommend to got Blackdragon 'll be better.

The board has stock cooling for everything but the cpu, like I said I got it from Newegg and just placed it on a test bench. I have a bad Cryo-Z mount on the CPU. I'm waiting the waterblocks from Mips, otherwise there is no way I can tight the Cryo down on he CPU.

The MCH problem I noticed right of the batch but tried to OC anyway. My DFI needed 1.75vmch and 1.50 to run 485fsb.

Yeah it is crazy I love this board I don't have a clue for my stable settings yet but my 556x9 (5004Mhz) was pretty comfortable on 1.44-1.48vcore.

All that on a old OCZ PS 520w PSU.

So I think I can et more out of it and start aiming for a reasonable 24/7 setting.

[yomny]

@fATGUY.,,, Thanks ill give that a try, i have my ram lat 333mhz and 2.00 which set it at 667, its a 1:1 and its underclocking my ram so i really dind't think it would be a problem but ill give your settings a try.. thanks

Ok good luck

[X.T.R.E.M.E_ICE]

Am i the only 1 here on the forums with a UD3L?. Just want to do some reserch before i start overclocking.

Also does it have a differant bios from the other models?
