EP45-UD3LR BIOS help overclock error message

Re: EP45-UD3LR BIOS help overclock error message

I think of VID as being the maximum voltage the cpu should need to operate at standard speeds.
In my case thats shown as 1.225V, for your apparently slightly different cpu revision its shown as 1.25V.
Is 1.25V shown in the bios health section at standard settings when you boot up?
Anyway what it seems to indicate is that for any given cpu speed you may need a little over 2% more voltage than I do.

I'll have to look and get back to you, and will edit my post.
I looked in BIOS health section and it says 1.268v and in MIT the values are set to 1.28125(now changed down to 1.268 to try) and in CPUz in my post the listed Vcore or VID is 1.25v Using the hard fast rule to allow OC speeds the Vcore would be 1.25 + .05 = 1.3v right? But that would be for OCing up to 3GHz or 3.5GHz correct? I think the best course of action is to start with a low CPU Vcore say 1.25v and begin to OC then when problems start to occur then we need to think about upping the Vcore to +.05V for stability. Of course I am not a Genius OK. :)
11-22-09 Update I changed the RAM settings to 5-7-7-24 as listed in the BIOS settings to the left to try as well. :)

Re: EP45-UD3LR BIOS help overclock error message

The thing is you "should" be able to run 3Ghz cpu speed without any real problems on your board if the memory is halfway decent and it seems to be ok.
For a day or so after i got my Q8200,while I was waiting for mbrd delievery I was limited to 2.8ghz max cpu speed on an older(GA 73 PVM-S2) mbrd.
There are a couple of reasons for that,chief among them is that there is no memory voltage adjustment on that mbrd series.(it gives memory V of 1.8 v,thats all u get)
That would be even with the intel standard cooler.

There are a few ways to test,but:
To get yourself off that 2.4Ghz cpu speed .
Force the memory to run on a 2:00 multiplier..
That is, if you set a cpu host frequency of 370 mhz:
1.your memory should be running at 740mhz ddr2 speed(undercloked yes but it should give you a feel for the mbrd)
2.Your cpu should be running at 2.6ghz(when loaded)

With most settings on auto the only ones that should need changing would be cpu core and perhaps mch voltage.

With your optimised settings loaded ,you would force the memory to run at only the cpu host frequency x2.. which would be a 667mhz memory speed at start.

Keep the memory at only cpu host frequency x2 as you go up in speed.
You should only have to vary 2 items, the cpu core voltage and mch voltage initially.

Perhaps as you get closer to 400mhz cpu host frequency you may have to increase memory voltage also.

dont go over 1.35v in bios for cpu core,dont go over 2.2v in bios for memory ,dont go over 1.35v in bios for mch core while going up to 390-400mhz cpu host frequency with everything else on auto and you shouldnt have any problems.

You really shouldnt need those voltages and should end up with around 3.0ghz cpu speed without strain.(in theory)

Once you get there you should have a good feel for what to do next.

Re: EP45-UD3LR BIOS help overclock error message

You need to set your own memory timings, auto is killing your performance!

[kick]

Re: EP45-UD3LR BIOS help overclock error message

Yes as Lsd is saying you will have to put in your own memory timings.
in the 5-7-7-24 :The 5 isnt too bad but the other timings are way out there.The jedec 0# timings and voltage should work ok up to 400mhz cpu host frequency BUT why not just put in the EPP1 settings for now just to be sure .
They are settings for memory running at 1066mhz,if u hold the memory speed down to 400/800mhz that should take the memory out as an overclocking bottleneck for now.Give the memory 2.1v in bios for extra security.
Get the cpu host frequency up to 400mhz in stages after that .
You have 380 working now (2.66Ghz cpu),
Get to 400 or actually go for 399 (2.8Ghz cpu) and if you are unsure what to try next, post all your bios settings at that point+ whatever screenshots you have.

Right I was just testing the 5-7-7-24 settings as they were displayed in the BIOS next to my 5-5-5-18 settings. but I guess they are not as good as 5-5-5-18 like you are saying. I will look at the EPP1 settings and test - investigate soon. I see them now its 5-5-5-15 at 533 speed.
Ok will try 399-400 tonight after work with EPP1 settings and RAM volt at 2.1 too. then will post screenies as well Thanks

Re: EP45-UD3LR BIOS help overclock error message

I do suggest you don't use EPP settings, unless you meant manully entering them and only mentioned EPP because you meant "look at EPP / Set manually"

Good luck and Happy Turkey Day!

Note I do not expect any answers on the holiday break.....

OK starting with manually entered 5-5-5-18 values then will try manual 5-5-5-15 settings. I have reached 400 BS and 1066 memory speed to get a clock speed of 2.8GHz I think. Here are some screenies and will follow with BIOS settings later. also testing for stability would be a must as well with prime 95 or OCCT or any rec tool. Getting awfully hungry for turkey and beer

Re: EP45-UD3LR BIOS help overclock error message

So you are reaching some stability now right? If so great, keep at it and let me know if you need further help in tweaking for performance as some of those settings are very loose.

Turkey sleep has worn off now So I can help tonight if you are around and waiting

Re: EP45-UD3LR BIOS help overclock error message

Yeh i meant enter the epp settings yourself.The xmp/epp option in the bios doesnt work for everyone.

As of your last post you are on 2.8 Ghz at 400mhz cpu host frequency (1600mhz fsb)
From here on in you wil lhave to assume a few things.
1.your memory probably wont work well above 1150mhz
Consider a maximum of 1100 mhz for now.
2.you have to increase the cpu host frequency speed to get your cpu running faster. A 7 multiplier is its maximum.
3.from the above you wont be able to use the 2.66 D multiplier much longer
2.66x410 would be 1092mhz mem speed ,x415 would be 1106 mhz/
Unfortunately at 415 your cpuwill only be running at 2.9Ghz

That means you will be using 3 possible multipliers from then on 2:00B,2:00D or 2:40B.
Its not the end of the world tho as increasing the cpu host frequency and hence the cpu speed/fsb speed also increases the memory bandwidth.

You have headroom on cpu V, mch voltage and memory voltage to play with.You know the memory will run 1066mhz at least, on the board.

Go for 415 cpu host frequency using the 2:66D multiplier if you like,maybe you have some phenomenal 1066 mem that will go much further even but it isnt likely.
Id go next for 450-460 cpu host frequency,in slow stages using a 2:00B or D multiplier.
You can probably get away with varying only the cpu core and mch voltages until then.After that u may/probably will have to vary some reference voltages etc.

Stick with do not exceed voltages in bios of 1.36V for cpu ,1.38V for mch and 2.2ish V for memory.
You shouldnt need near those voltages for any of the components while going to 3.1-3.2 G cpu speed or 1800-1850 fsb .
The memory itself will already be on Cas 5 timings and DDR2 speed of only 900mhz so shouldnt need excessive V either.
If things dont work out post your highest cpu speed stable bios and people may have more suggestions.

To Lsdmeasap and Kick,
These settings are loose? you must be refering to settings other than memory right as the 5-5-5-15 is rec by memory manufacturer AFAIK. New link for memory 996599 - 4GB (2x2GB) DDR2 PC2-8500 5-5-5-15 Blackline (Dual Kit)
You may be refering to the other settings that could be lowered under Advanced Timing Control.
Kick I was only planning on a moderate OC with this board as its going to be my backup board for storage and other projects. The recent OC activity has got me thinking just how fast this board can go, but the potential for damage is nagging me now. I had planned to OC my other board, GA-EP45-DS3R, but have been guided to the UD3 series for its cooling properties. At this point I am also considering selling some builds and then reinvesting in other better boards. Finances, are also a consideration as well for me being on a low budget. My main reason for learning to OC is to use and OCed board while gaming and not blow it up in the process and to learn more about BIOS settings too. I have a Electronics Technology Degree and desire to do something with my knowledge.
I guess the question is which board is a better OC candidate the DS3R or the UD3R?? Sorry if I have mislead you in any way, but I am looking for a moderate OC that is stable for everday usage and allowing for my parts to not burn out too soon, for the Backup PC whatever that turns out to be.
Thank you for your information on OCing. You seem like you are really knowledgable in this area.
PS adding other stick of RAM for 4Gigs total. Also added the extra fan on the Northbridge for stability testing at current speeds.

Re: EP45-UD3LR BIOS help overclock error message

Yes, your memory timings shown in Memset above are VERY loose (Bad Performance), and ya I meant the Advanced settings.

The Normal P45's such as DS3R cool just fine, no worries on that! I have a DS4P and it is just fine at super high clocks.

Let us know if you need more help, good luck tweaking and testing until we meet again.

Re: EP45-UD3LR BIOS help overclock error message

To re-flash your saved bios version with its profiles, QFalsh requires that the saved bios file is in a FAT16 or FAT32 partition. If you've saved the file to a FAT16/32 flash drive, I'm pretty sure that QFlash can access the USB drive, even if Legacy Storage Detect is disabled in your bios.
It's best to test this out ahead of time, as this setting is required to be enabled if you want to boot from a USB drive.
