EP45-UD3R: need bios help

[pool4eva]

Ep34-ud3r ver 1.1 F4 mobo
9500gt 1gb ddr2 video card
OCZ reaper 2g ddr2 1066mhz 2.1v (4 sticks= 8g)
Intel core quad Q9550 @ 2.83mhz
Window Vista 64bit ultimate

ive updated mobo. mem voltage at 2.01 1066mhz. It runs fine at with 2X2g of mem. When i put all 4 stick in, windows becomes unstable. After couple minutes, i get the blue screen of death. after reboot, it says i have problem with hardware or a problem has occurred in windows. Ive done memory test and all checks fine. I even swapped out the original 2 sticks with the other 2 sticks and it still runs stable with no problem. This mobo suppose to support up to 16g and i cant even get more than 4g to work. Ive been reading forums and people say the bios needs to be set up correctly but i cant find the problem. Can anyone post a setup for me. Im not a computer genuis but i can follow simple instructions. Ive tried adjusting the voltage down to 1.2 and speed to 800mhz but still no luck. This has fustrated me for 2 months now and gigabyte tech support is no help. Please help!

Re: EP45-UD3R: need bios help

We would need more info than that.
Copy this, paste it into Notepad. Run ET6 and Memset and fill out the values. What you can't get from there, get from your BIOS with pen and paper and then add it to this and post it here.

Here is a link for Memset Save the zip file, extract it to a folder in Program Files, then run it.

I am assuming that the UD3R BIOS is the same as the UD3P BIOS, if not, then I am sorry...

Re: EP45-UD3R: need bios help

2 months is looong.
Aside from the usual disclaimers of .. buy a matched 4 stick set ..or see if the memory is certified for your mbrd.

I ran a set of value ram 5300 samsung with my 6400 gskills loaded optimum defaults ..everything on auto then put in the 4 sticks.. it went to around 350 mhz 700mhz on the 8 gig which is about what you would expect.
Ie the bios dumbed down my 800mhz memory.


Check the profiles on your ram if theres a 333mhz profile on it enter those settings for 2 sticks turn it off then reboot.
Or just enter standard 333mhz timings + volts(1.84) for 2 sticks save n then turn off n put in 4.

If it works ok u can save the settings n gradually work up from there.
Or possibly upgrade bios?

Re: EP45-UD3R: need bios help

Oh, in Memset, Write to Precharge Delayed = tWR.
All Precharge to Activate = Not in your BIOS/Auto
All Precharge to Refresh Delay = Not in your BIOS/Auto

Re: EP45-UD3R: need bios help

still no luck everyone.. ive already tried what KICK suggested. GRSIHKAFOOL, im a newbie so is the memset in bios? My friend help me build this computer but cant help with the settings.

Re: EP45-UD3R: need bios help

Memset is a program that lets you see your Memory Timings on your Desktop.
Here is a location for a zip of it. You can actually use it like ET6 to make small changes on the fly to your memory timings (ET6 can make small changes to your voltages); when you use it for that you can click Apply, BUT NEVER CLICK SAVE

Anyway...
First I think you should try the following:

DRAM Performance Control
Performance Enhance...................: TURBO <------Set to Standard
Extreme Memory Profile (X.M.P.).....: AUTO
(G)MCH Frequency Latch...............: AUTO
System Memory Multiplier ......(SPD): AUTO
Memory Frequency (Mhz) ..............: 1066
DRAM Timing Selectable .......(SPD).: AUTO

Then launch Easy Tune 6* and record the actual values for:

CPU Vcore….……….......1.3750V..............: AUTO
CPU Termination…..... 1.200V*...............: AUTO
CPU PLL…………………....1.500V*...............: AUTO
CPU Referen.…………....0.760V*...............: AUTO


MCH/ICH
MCH Core…………….....1.100V...........: AUTO
MCH Reference….…….0.760V............: AUTO
MCH/DRAM Ref.…......0.900V..............: AUTO
ICH I/O……………….....1.500V............: AUTO
ICH Core…………...……1.100V...........: AUTO

DRAM
DRAM Voltage ……....1.800V............: 2.100v

To find them in ET6 click "Tuner" tab, then click "Advanced" tab, then click "Voltages" tab. Your BIOS is set to Auto, but ET6 will show the actual voltages that are being used. Essentially, you are saying that you can put any two RAM cards in either Channel 1 or Channel 2 DIMMs and everything works fine; but when you populate both Channel 1 and Channel 2 DIMMs, you get a BSOD....

What it could be is that the AUTO setting for MCH Core might be using too little volts for 8GB of RAM. But we don't want to change anything till we know what the actual number is...

*I am assuming that you have ET6 installed on your machine. It came on the Disk with your Motherboard and you definitely want to install it if you haven't already.

Ok, let us know what you find.

Re: EP45-UD3R: need bios help

Two things I see that might be problems.
Your CPU Vcore-- you typed a 1.1375, is this a typo? If not, then that is a problem. It is too low. And the default value of 1.375 is too high according to Intel

Performance Enhance...................: TURBO

Did you change this to Standard?

Channel A
Static tRead Value......................... 6 AUTO
Channel B
Static tRead Value......................... 6 AUTO

Oh, this is definitely too low for 8GB of RAM, change these to 11 and see what happens.

Re: EP45-UD3R: need bios help

Some of the Memset displayed values differ from the settings in the bios:

Taken from Lsdmeasap's guide:

* ACT to ACT Delay (tRRD)________________ 3-4
* Rank Write to READ Delay (tWTR)_______ (4-6) 9-11 (Note Actual Value set in BIOS Vs. What system Uses will be 7+)
* Write to Precharge Delay (tWR)_________ 3-5 (Note Actual Value set in BIOS Vs. What system Uses will be 5+)
* Refresh to ACT Delay (tRFC)___________ 38-42 (2X1GB) 52-62+ (2x2GB)
* Read to Precharge Delay (tRTP)_________ 3-6 (Note Actual Value set in BIOS Vs. What system Uses will be 2+)
* Static tRead Value (tRD)______________ (5/6) 7-10 (800Mhz) 7-12 (1066Mhz)
* Static tRead Phase Adjust______________ 1-31*

Re: EP45-UD3R: need bios help

His CPU Vcore is fine as it is. It's not uncommon for E0 quad cores to have VIDs that low. To verify you can run CoreTemp, it will show the VID programmed into your specific CPU.

Try the following settings, with particular emphasis on disabling XMP (useless), setting performance enhance to Standard, MCH voltage changes and advanced timings lossened (including tRead).

You may be able to lower Static tRead later but try that for now.

Don't worry too much about Memset, and what the values mean. The advanced settings in the BIOS are all you really need to know, and that bigger numbers can give more stability.

[grishkafool]

Re: EP45-UD3R: need bios help

Psycho, you have tried to get me to get real low on tRead with my 8GB of RAM and it always causes me to lock-up. I haven't had any stability with that much RAM below a tRead 9... is there some other association that would impact tRead that I am not grasping yet?

[Psycho101]

Re: EP45-UD3R: need bios help

Afer all the testing I've done the only major factor I've found that changes the stable tRead value is FSB speed. Are you stable at your default speeds with anything lower than 9?

Before I got rid of a set of Corsair XMS2 6400C5 (5-5-5-18 @1.9v) I was able to test 8GB, and got it to DDR920 (3.22GHz CPU speed Q8200) with tRead=8. This was the same tRead I used on my current PC2-8500 at that bus speed. They also did tRead=6 at 333 FSB. I only ran Prime for a couple of hours as I had no intention of keeping the modules.

It may be that the OP will find that they have to set higher, but to avoid loosening timings too much I suggested a value that's one up from what auto suggests for the 4GB. Hopefully it should boot, but if not it's definately a likely suspect to tweak, but not the first thing I'd do. I'd probably add a little more MCH, and if that didn't work I'd enter extremely loose sub-timings like 8-8-12-86-8 and set tRead to 12.

Re: EP45-UD3R: need bios help

grishkafool: its not a typo error. cpu vcore - 1.1375. this is the default setting. what should i change it to?

[Psycho101]

Re: EP45-UD3R: need bios help

You don't need to change your Vcore to anything else. Auto is fine if not over clocking. Each individual chip has its own VID value. This VID is the voltage auto will set at default speed. You have a chip with a low VID, that's a good thing.

[pool4eva]

Re: EP45-UD3R: need bios help

psycho101: i just changed to the setting you gave me. all it did was reboot over and over so i changed it back to default. you posted changes for pci express frequency to 100. performance to standard. system mem multiplier to 3.2. mch core 1.24. tWR - 8. tRTP - 78. command rate -2. channel a and b tRead value - 7. it didnt work. sigh...
