same OC's results.

i dont think so. some people here in italy have ud3r rev1.1 and they aren't able to go over 450fsb. ram only in 1:1. it hasn't same performance of rev1.0
obviously, not all rev1.1 are so bad

[pangingIII]

i’ve not spent much time with this ud3r (rev 1.0) ddr3 board yet, it's just not like i used to have a lot of time with the ddr2 ones.
but anyway, i just have some time to play with the board again and share what happens.

this is the first time running prime95 to test some of my voltage and ref. voltage settings.

well i have 1.1 GA-EP45-UD3P and its easy to get 450fsb I can get 4GHZ stable on my X3350 but its when i get closer to 500 i need more CPU Termination & MCH Core then below 500

and on my E8500 i gotten 7.5X600

All I can say that I had some extensive testing done on both UD3P Rev1.0 and Rev1.1 in several different boards and they are all the same to me. Same voltages for same clocks and voltage stability also the same.

Coming up my new IBT&Prime95 stable Q9650@4680Mhz (520x9) rams at 1300Mhz PL8. I only needed 1.32vtt but MCH Core is needed a little bit more then usual from 1.45 to 1.60.

Vtt for 4752Mhz stable also doesn't need to go higher then 1.36vtt.

[radaja]

jor what was the pll needed for that?

well i guess you just got some good Chips and i still need to mess with the ref volts

[radaja]

got my replacement today,it is a different board,rev 1.0 and now i'll have to see what this board likes.im installing xp right now.so ill be back with an update on how well it performs.BY THE WAY IM ONE HAPPY GUY RIGHT NOW,VERY EXCITED.its almost like when i first got it

[SpeedEuphoria]

Lets talk about Memory bandwidth and stability with MCH voltage. I noticed on my board that 1.22Mch works good as well as 1.26 and 1.32. If I set 1.24/1.28 I loose bandwidth. Another user has backed this up as well. He found that using the 1.24/1.28 that loosening the sub timings gained back the lost bandwidth that 1.22/1.26 MCH provided, very strange indeed.

I will have to step up and do more thorough testing now that it has been confirmed, to see exactly what is going on and to see how/if stability is affected as i never messed with the MCH that gave me less bandwidth.

[kagula323]

Tomorrow I will receive my new UD3P. Verry excited ... But currently I have only an E2160 CPU. Do UD3P OC well E2160 CPU-s? Can anyone here share some settings and results with this combo?
I had a C0 E8400 that was a verry bad clocker ... sold it and now I have a thougth time deciding what CPU should I choose in his place ... I'm currently trying to decide between E8400,E8500 and Q9550. I'm tempted to choose E8400 because the big oc's attained on them that i see in this thread ...
and I kind of got the impression they tend to oc higher and easier than E8500's.
But the order for the cpu is gonna happen next week only . Just wanna see what u suggest ... what u preffer ... E8400 over E8500 or E8500 over E8400?

[Jor3lBR]

jor what was the pll needed for that?

Hey Rad the PLL needed was between 1.5 to 1.56 nothing more then stock will do. I will post settings soon again but I have to try this out on the UD3P as well (latest 4860Mhz_1300ddr2 was achieved on the Extreme) but I always find the A03 on the UD3P less moody to setup.

well i guess you just got some good Chips and i still need to mess with the ref volts

Nah no hand picks here I got a old batch from eBay when these first came out. Then I got a chip for a friend (SergioAndres) and said that I would deliver with UD3P running Prime95 stable at 4500Mhz with less the 1.4vcore and 1.32vtt on his cpu. So no matter the chip these board can put them to good use

[pangingIII]

testing DDR3-2000 with dual SuperPi 8M and a SuperPi 32M (for stability test only) on this exceptional quality and low price board





i also hope to get DDR3-2100...





and might be DDR3-2200. the board already boot with an overclocked ram and at this ram speed, just couldn't get into Windows yet.

[Hoss331]

Try BIOS F9a released today.

There is a bug on the 2:40b strap that wont let you boot with 2 sticks of 2Gb above 1.4vmch set in Bios (some can go higher some lower).

You can use 2:40B strap as long as your Vmch in bios is around 1.40v. You can change that thru ET6 later if needed.

So try to boot 1066 with 2:40b strap and low Vmch then report back.

Here is what I have come up with. On my board(And apparently Hoss's board as well) the voltage for MCH has nothing to do with getting the 2.4B multi to boot. At 9x470FSB I have tried 1.34, 1.36, 1.38 and 1.40 MCH voltage. All of my attempts failed to boot. I began lowering the FSB down from 9x470 in 10mhz increments, at 430FSB all of a sudden I was able to boot into windows no problem(This was done all on 1.34/1.34 MCH/VTT). After I was able to boot at 430FSb I began raising the FSB by 1mhz untill I could no longer boot. I discovered that as long as the FSB was under exactly 435FSB you can boot with 2.4B and above 434FSB you can not boot with 2.4B strap.

All that said, the 2.4B strap is the most important one for myself to use with my 9x470-9x475 clocks because of the limitations of my 1100mhz RAM. Because the single most useful RAM multi to me is bugged I am really getting pissed at Gigabyte for not having this thing fixed already. I have been booting at 434FSB and then raising the FSB with ET6, however there is a problem with that. One of my programs(Fritz GUI) will not recognize the change that ET6 has made, even though my processor is running at 4.23ghz the program is reporting 3.9ghz and this is causing very annoying performance issues with my game engines.


Does ANYONE know if Gigabyte is planning on fixing this problem in the future? Has anyone contacted Gigabytes support people about this? If there is a good e-mail to reach them at let me know and I am going to start bugging the out of them until they resolve it in a bios update.

[firas]

aha ... so the "MCH/DRAM Reference" is somehow connected with A/B reference?
I’ll set it to 1.050, but do you think I should try to lower the ram voltage a little bit?
2.060 with 1.030 A/B reference and MCH/DRAM Reference? like what you gave Hoss331 ?

will set it to standard, I just kept it to Turbo cuz that’s what it was when everything was at stock

do you think I should set “Static tRead Value” at 8 instead of 9 like your settings? Specially that mine already shows 8 as a default value!

didn’t really understand but I’ll give 266/2.50A a shot
you mean "CPU PLL"? it's @ 1.50 not 1.15

manny thanks for all the help everyone

Sure lower it away, if it passes keep lowering it


SURE! That is what I was meaning about using standard and trying better Tread values and write training. Set your to stardard and see how low your Tread value will boot, that is after you get your multi and ram speed set to your liking.

I would follow Hoss331's advice with setting a higher RAM Multi, Hoss helps me with my settings and is pretty good at this stuff.

I would not worry about the Thermal Monitor and your current overclock. Your not going to experience high load temps so Thermal Monitor is going to be useless for you. Even at my clock speeds sometimes I do get my chip a bit hot(If I linpack) but the important thing to do is monitor your temps and even if they get above 70C as long as your not running that hot for a long period of time your not going to "fry" one of these Q9550/Q9650 chips.

266/2.50A didn’t work … BSOD during windows startup.
anyway latch@333 with multi@ 2.04B is good for running@ close to stock for me (1020)

i wonder why ET6 show 0.9 for DRAM Termination & channel A/B reference & MCH/DRAM reference though they are 1.050 in bios!
after work i'll try 2.060 with 1.030 , if it worked i'll give 1.920 with 0.960 a shot

I managed to pass P95 at like 1.16** vcore, can I set it to that or it’s not a good idea to go below stock?

ET6 does the same thing for me. If your current overclock is passing 1.16vcore small ftt's in prime 95 that means your CPU is stable at that speed. For me that would mean time to test my ram/nb in a blend using the same CPU vcore, if the blend passes several hours then you got your stability for that overclock. Settings look fine, I do not know if your setting your MCH reference correct but your RAM references look good. Good luck with your Blend!

hi lads
I bought this after reading countless good reviews and have played with it for some time,only managed to get 5 different sets of ram to run at a max of 1120 mhz, that was 2gig kit of crucial ballistix on 5-5-5-15, tried this with corsair pc2-6400c3 - no go there - had crucial tracer 2gig - no go - had 2gig kit reapers pc2-9200 - they were unstable on this board - got 4gig pc2-8500 g-skill they can only go 1080mhz - do i need to loosen those timings a bit - thinking about team xtreme aswell but they are quite expensive,maybe its the cpu which is limiting me.
i have a xeon 3045 - quite hard as only have multi of 6 or 7 - 450fsb -hate the ram options on this - linked to fsb,so anything above 450fsb - u need ram that can hit 1100mhz -think that is not great-given that this board is capable of running ddr2 ram at 1366+ mhz
did have a qx9650 for a couple of weeks,but as soon as i altered voltages the temps on the cpu rocketed,so i sold that- i like the xeon as it runs ultra cool just struggling to find the right set of ram that can take me higher.
wanted to also ask in the bios on health management what things in there need to be disabled,and what ram recommendations would you lads suggest,
any advice would be great,cheers in advance

Here is what I have come up with. On my board(And apparently Hoss's board as well) the voltage for MCH has nothing to do with getting the 2.4B multi to boot. At 9x470FSB I have tried 1.34, 1.36, 1.38 and 1.40 MCH voltage. All of my attempts failed to boot. I began lowering the FSB down from 9x470 in 10mhz increments, at 430FSB all of a sudden I was able to boot into windows no problem(This was done all on 1.34/1.34 MCH/VTT). After I was able to boot at 430FSb I began raising the FSB by 1mhz untill I could no longer boot. I discovered that as long as the FSB was under exactly 435FSB you can boot with 2.4B and above 434FSB you can not boot with 2.4B strap.

That is your board specifically then Slim, I was testing with stock settings and 4Gb, all same results 2:40 is bugged for any volts above 1.440vmch no matter Mhzs...

But that doesn't mean you can't solve this problem, as I said many times before but people refuse to read, just set 1.40mch in BIOS, boot into Windows and use ET6 to raise it.

I'm using 4Gb's at 1250-1300ddr2 PL8 using 2:40 strap above 1.5vmch with no problems here.

[PortCitySlim]

No, Hoss's board did the same exact thing with his PC28500 ram. He recently picked up some new RAM and now his board is acting a bit like yours, except he can not boot at 1.38 and above.

I will let him reply to this if he wants to with all of his test results. To me this is starting to look like a RAM compatibility issue with certain RAM kits.

But that doesn't mean you can't solve this problem, as I said many times before but people refuse to read, just set 1.40mch in BIOS, boot into Windows and use ET6 to raise it.

No, sir, I read that and then I replied saying that this does not solve my problem. Yes, sure I can boot at 434FSB with any MCH I desire and then use ET6 to raise the FSB to 470-475. My problem is that after using this ET6 program that some of my applications do not WORK PROPERLY because they are reading the information that I boot into windows with and even though ET6,CPUZ, OCCT and Coretemp all display the 4.2ghz, the program I use a lot does not. It will(I think) run at 4.2ghz sometimes but what gets me is that it has a built in benchmark and it should benchmark at about a relative speed of 25 at 4.2ghz, problem is that yesterday I was noticing it acting up and I benched it and got a RS of 22. I reset the computer and tested at the original boot speed and then used ET6 to raise the voltage and benchmarked it again, this time I got the same results as before only hitting a speed of 22.

I wasn't referring to you I saw you did read and did respond to it

Well that's strange I've been using ET6 on 3 OS's (WinXp64, Vista and W7) and it's working well, but as you said it's with a specific software you like to use.

I agree that the ideal solution would be a fix from the manufacturer but this is very unlikely to happen because fixing a strap sometimes will result in crippling another one.

Most boards these days always have a week strap.

I understand. There is good news I hope on the horizon, if you remember I was asking you about a 2x2gb kit that could hit 1200. Well turns out I might only need 1175-1185 and 1200 would be icing on the cake. I have been talking with Hoss and he picked up this kit and so far he is getting good results.
http://www.newegg.com/Product/Produc...82E16820227406
I might buy this kit because Hoss said it fixed "our" problem of not being able to boot at certain FSB speeds and that it defaulted to your problem of being linked to the MCH voltage.

Yes that may be a good try. I've tested Crucial, G.Skills, Kingstons and Teamgroup but never those new OCZ's PC2 9200.

If that works and clocks well would be a great alternative to $300 G.Skills PI.

I just wonder why my kit and Hoss's old kit would not boot over 434FSB/2.4B/1.34MCH(we both got the same results with seperate kits). When he got his new kit that problem went away and he started noticing the problem you described with not being able to boot over a certian MCH voltage. Makes me wonder that even though the strap is broke that maybe a new bios would fix the compatibility with the few certian kits that gave the problem me and him had.

here are my new g.skill 2x2GB.just a quick test for vdimm needed.
