[Loco23]

I've said this countless time. I use my stable settings with the Vdroop control disabled and all the C1, C2, EIST, Thermal Management estates on Enabled...

Jor, sorry, but i did not understand you: you use LLC or not? On your screenshot LLC is on.

[andressergio]

Jor, sorry, but i did not understand you: you use LLC or not? On your screenshot LLC is on.

i talked to Jor last nite yes he dont use LLC but you need to restart your OC again mate, i tried last night and for ex...

i have 4500/1200 stable at 1,392Vcore CPUZ load / idle (1,43125 BIOS) LLC ON

So i went and disable LLC and had to set 1,4875 BIOS to get those 1,392 cpuz and then i enabled all CE states, but vcore does not drop as i talked to Jor or i get it wrong, just multi drops to 6, so i get 500x6 at 1,392.

Mi quad needs 1,392 at load to blend stable so im kinda confussed with this will have to try more, if im not wrong with LLC OFF vcore on IDLE will be higher all the time and on load will need 1,392 to pass tests.

Plz Jor correct me if im wrong

Cheers mate

Jor, sorry, but i did not understand you: you use LLC or not? On your screenshot LLC is on.

I don't use LLC until my OC is stable and would never use it for bench runs. It's really up to the user.

I prefer to use the C1/C2/EIST estates that will give the cpu a break when idling.

But this is theory really, today we have much better and 'cleaner' power regulators in the mobo and coming from the PSU's then they had back then when Intel designed this system I don't see any reason why not to leave LLC Enabled.

Sergio you are wright. With LLC Enabled you will have more vcore when idling 6x500. Then it will drop a little bit when under 50% of load, for example, and it will drop fully when 100% load. If you want to reduce vcore when at 6x500 you can do it by software.

I would leave LLC Enabled and only mess with C1/C2/EIST estates.

ok guys dont mean to sound dumb here, but im still learning.. i hear people talking about LLC and GTL. what are they and how and why do i use them or not use them? shoot me a PM if you dont want to clutter up the thread that is fine... i just cant seem to get my Q9550 any higher than 3.6-3.7ghz stable. the only thing i have adjusted is vcore(cpu) mch(which is NB right) Mem volts. and mem strap.i have that set at 2.00d. now i do have the EP45-DS3R. not a UD3P/R
i did just get some ddr2 1066 mem(corsair dominators).... or is this board just at its max with the fsb as high as it is to get a higher OC????

there is a azz everywhere you go. if your not gonna help dont post. i came to this site cause people help each other unlike other sites. i see you must belong to one of them other sites. why dont you go back and enjoy.

for the rest of the good people here. i have not seen anywhere on my mobo anything that says LLC?????

[dustin_ds3000]

ohh come on dont be so tight, it was funny. well anyways LoadLine Calibration reduces the vdroop. i use it but im not a PRO at Ocing

[Jor3lBR]

for the rest of the good people here. i have not seen anywhere on my mobo anything that says LLC?????

If you don't find anything on the M.I.T. Bios menu that says: Loadline Calibration, then your mobo doesn't have that function just like the Extreme and DQ6, they don't have it.

[cincyrob]

ive been looking at some code shots of other UD3P/R boards and it seems to be along with EIST and C1E so when i get home i will give it a look see.

I dunno, man, I dl'd and scanned through the manual for your board last night and I don't see LLC/GTL as being features displayed on the BIOS screens shown there. Going to be kind of a tough row to hoe trying to get advice on your board in a thread devoted to *other* boards. There *are* other people running your board - might want to search out threads for those. Just my $0.02, don't shoot the messenger (or call me an "azz").

Just sharing my results.... still waiting on parts upgrade, but I thought I'd share this.... posted in the q9550 thread.

I'll see if I can push it further; my ram sucks... but oh well. PSU is hanging in there too.

What kind of vdrop is everyone getting with these boards with LLC enabled? I have a chart I'm going to put up, when I get home today and I'd like to compare notes with you guys.

I have noticed a few areas where 1-2 bumps in bios vcore will keep the cpuZ voltage the same at load. Also, there are a few voltages I can set in bios and cpuZ will bounce between two values at full prime load (like they're in between).

Additionally, I just put my new ud3r in a few days ago and I'm getting slightly lower cpuZ voltages as compared to my old board at the same bios settings. I'm a little bummed about that one.

I to have noticed this weird spot where it stays the same as well. For me it is at 1.3475 and 1.35v. It will hit the 1.296v spot on both but, the voltage is a little higher when idle though I noticed with the 1.35 setting. I put in a new Corsair HX850W power supply last night as well so if, I had any PS issues they are gone now. It is a very nice power supply.

I have also noticed that if you use Intelburntest when first firing up the mother board you will get lower GFlops for a little while and slower completion times with it as well at first. Then as I reboot it and bench it more it will start picking up and getting eventually back to what it should be pushing. I have been utilizing Intelburntest by paying attention to the completion times and how many GFlops the CPU pushes out and by paying attention to the temps on the cores as well to tweak my GTLs to perfection, very helpful there.

This morning, I went ahead and bumped up my FSB Term voltage to see what happens and I noticed that it bumped the speed back up to normal instantly but, I have it set @ 1.4v now. That might, have been my problem there but, I am still poking around with it here and there to better feel that one out. Also, the GTL wanted to be set back to around the .88 spot when I bumped the FSB Term up.

This board wants to adjust your CPU Reference GTL when you bump FSB Term up and my board really seems to like being around the .88 reference spot. Maybe this is normal and I am just noticing it for the first time but,I am sure this info will serve some people well some where down the line. I can post other interesting quarks as I come across them if people like.

[Zucker2k]

What you both are describing is not an anomally, but rather bios design. The voltage feedback or registers are measured at defined increments, unless you exceed a threshold, no change is registered. So a very fine voltage adjustment may be within a defined threshold and therefore won't necessary register even though the effect is manifest. So eg. 1.4250 and 1.41xx may both register 1.3920v because the register threshold has not been crossed.

[bluestang]

This was discussed once already on pages 175 and 176. As I mentioned there...BIOS can adust vCore in steps of .00625, but CPU-Z reads in .016 increments only.

[maxgull]

here let me help you

http://lmgtfy.com/?q=Load-Line+Calibration

LLC may or may not be on your board, it helps prevent vdroop of the vcore voltage (loaded) when enabled. GTL is a reference voltage, different BIOS's call it different things. on your board it is CPU reference voltage (i think) in the MIT tweaker menu. you set this by taking your CPU voltage and multiplying it by .67 (standard) and select the voltage closest to the result. Some ASUS boards display the percentage in decimal form IE .67, .63 etc. for the cpu & NB reference setting. usually the percentage for CPU is .67 and the NB .63. IIRC...

Zucker2k: Excellent results on your q9550.

lol its not like that Karl some people dont have anythign to add to a convo and just want to play games. i dont get into that. we are here to learn and help others.im kinda new to all this, and yes i have googled alot of stuff that i have tried so far, so i dont need someone goofin off trying to screw with sonmeone for no reason.

and you are right i did not see anything in the manual at all about LLC or in MIT. as for my board i think there is only 4 people in the world that have it. it sucks i think.. i will soon be getting a UD3P. thanks for looking into it for/with me..

maxgull
thanks for the info. no i have seen the CPU ref volts (GTL) before. i have never messed with them so i will look more into it.
i know this chip will do more than 3.7ghz i just ned to learn what to tweak and what things are called on this board until i get my UD3P...

sorry guys didnt mean to stir the pot.

Yes, confirmed by me and 1tanker a few pages back. I bumped up voltage in BIOS that went unchanged in CPU-Z or any type of software monitor, but with DMM the change registered and it made a previously unstable OC, stable.

[Karl_in_Chicago]

@cincyrob - you might want to give this thread over at tweaktown a read. 39 pages on your board and a q9550. Not promising it's going to contain the holy grail but it's got a fair amount of discussion on the setup you are working with.

Hey man, at least you are working with a 9550 - trust me, the 8x multi on a 9450 presents its own can of worms!

[shiver_8]

Hey guys, I'm new to the forums. I couldn't find a section for introductions, so I decided to come here since I have a UD3P and an E8400. I'll give my system specs: Antec 900, TX750W PSU, UD3P, E8400 E0 1.25 vid with an HDT-S1283 mounted on it, XFX 4890 (soon to have a second as soon as prices drop), 1TB Caviar Black, and 2x2gb of OCZ Reaper 1066. I have a question... Is there any way at all to acheive 5ghz on air cooling? Or am I just dreaming. I have my cpu at 500x8 right now with 1.29v and stock fsb, pll, etc. I just have the NB bumped to 1.4v. Also are there any methods that you can keep your OC stable while lowering your vcore? I see guys running 4.5ghz with less than 1.3v and I don't know if they have a golden chip or if they know something I don't. Anyways glad to be on here looks like alot of good threads!

Hello Shiver, There is no doubt the board is capable of a 550+ FSB, but as far as on air cooling, I dont know. I think at that FSB you might need at least H20 cooling on the NB. Im curious how other people are cooling there NB at high FSB and MCH. At 4.5 with less then 1.3, yes, u can safely say they have a golden chip, and probably a low vid chip also. Your vid is on the high side. For finding lowest Vcore run P95 smallFFTs, then move onto Blend P95. Alot of people are finding they need slightly more Vcore to run P95 Blend then they did running P95 small FFTS.

Ok thanks thats good to know. I just got my cpu running 500x9 p95 blend for 30 minutes and then I stopped it, because it needed 1.472v according to cpu-z to do so and the temps were getting to mid 70's. My guess is for 5 ghz I'd need like 1.6v on the NB, 1.7vcore+ and obviously the right cooling to handle that.

I have used 1.6 on the MCH, and Ive been getting freezes in 3dmark testing, the NB feels real HOT. Im gonna try having a fan blow on it and see if that helps. Of course the freezing could be due to something else, only time and testing will tell.
