Re: Need help getting UD3R+E8400 to 4.0!

Okay Outer, ran those settings, everything seems to work well, even ran a small 3dm Vantage test and recieved a couple hundred more CPU points. So currently running at 3.88GHz. What should I do now as the next step?

Thanks so far! I really feel like I'm gonna get a 4.0 stable with your help. :)

Good, Good. By my estimates, you can go as high as 438 x 9 on the CPU, taking you to 3.94 GHz. I don't think you're going to get stable beyond that, no matter what you do. At that clock, your memory is going to be begging for a wee bit of mercy.

I don't think you really ought to relax the memory timings any more, because that's only going to give you diminishing returns. CPU clock may be higher, but benchmarks may actually decrease if they are designed to show the effects of memory latency.

My advice is to try 438 x 9 at current voltages and timings. If you are stable at that point, call it a day. If you can't get to 438 x 9, don't even bother with 433, 434, 435, 436, or 437. They produce funny multiples that are hard to iron out. Looks like your current 432 is going to do it.

Hope that helps.

Re: Need help getting UD3R+E8400 to 4.0!

Hmm alright man, but can't I really get to 4.0 if increasing vcore to 1.3v along with some other things (memory things)? I could always just increase the voltage of the memory right? (It's rated 5-5-5-12 @ 1.8v) Cause it's hard to believe my memory won't do anymore man.

I'll test the next step you gave me also.

But I find it strange, because I should be able to reach 4.0 with increasing the vcore to 1.3v among other things, because 4.0 worked with 1.3v and your 3.83 stable settings (all I did was increase vcore), but it eventually crashed after playing a while (and I also didn't seem to notice any change from 3.83 to 4.0, because Vantage gave me the same points, so something must've acted as a diminishing return or something), so there must be something we can still change right?

Lots of thanks though man!

EDIT: tried your settings with 438 [email protected], works wonders, recieved another couple hundred points (like 800 points) in 3dm Vantage, I'm going for now, I'll leave Orthos@blend running for a couple of hours. I'll let you know!

EDIT2: Ran Orthos@blend@priority 9 for 1 hours and 7 minutes, recieved no warnings or errors. So I should be able to get 4.0 with a little vcore and ram voltage increase?

Re: Need help getting UD3R+E8400 to 4.0!

For 4GHz your memory need to be at 900.
To isolate other settings, back off your clock to 375 with SMM 2.40B, Statiuc tRead 9-8, and run some stress tests.
One hour is not much. Run customized Prime95 blend torture, min FFT 128k and 6 minutes for each test for at least 2-3 hours, if it pass than 4GHz may be possible.

Re: Need help getting UD3R+E8400 to 4.0!

Can you send me a link to your exact memory? I looked it up, but I see 1.9 - 2.1V rating, not 1.8V. I need to know the exact product to make sure. The reason I'm a little cautious is that your memory is running at 876 MHz while it is rated for 800 MHz. That's a pretty hefty overclock for DRAM in a 2 x 2GB configuration. The processor will go higher with very little additional voltage. The memory however might not go any higher than 882 MHz no matter how much voltage you throw at it.

882 MHz on the DRAM will give you 441 x 9 on the CPU clock, but to get there, we'll need 1.94 - 1.96 DRAM volatge. Please don't try that until I get the link to the DRAM, because those voltages on memory rated for 1.8V will fry them quickly, no matter how good the cooling is. We're at 1.92V already, and only at 438 x 9 on the CPU clock. If you had 1066 memory, I could comfortably get you to 4.05 GHz without a sweat!

Re: Need help getting UD3R+E8400 to 4.0!

Sure man!

The best clocks we could manage were 900MHz 5-5-5-15 @ 2v

taken from a review for the 800G.



In the bios it says 1.8v stock, but yeah otherwise according to that pic its 1.9-2.1v, so it should be certainly 1.9-2.1v.

So how are we gonna do it man? (btw I tried 445fsb with 1.92v ram+1.29275 something vcore and it booted up, ran vantage, i recieved a couple points less than before lol, so prolly is the unstableness)

Thanks a lot! Oh and I would rather not really stress the ram you know! Would rather have it at a stable reasonable OC.

Re: Need help getting UD3R+E8400 to 4.0!

Great news! Your ram can easily take the voltage. We should have more headroom available. Take DRAM voltage to 2.0V. That's a comfortable mid-range value that should be quite stable. Make sure CPU voltage is 1.3000V and 445 x 9 on the CPU clock.

Test for stability with those settings. When you get a chance, can you post your full settings? We may need to bump Northbridge voltage if you see numbers decreasing in the benchmarks.

To get a rough estimate of stability, try the Intel Burn Test. This is very demanding and will stress things hard. If you're stable with that, then you can do longer overnight ORTHOS tests.

Re: Need help getting UD3R+E8400 to 4.0!

NICE MAN! I will do everything you said! master!

Okay so I will try those settings, then run 3dm Vantage, If I get less points again, I'll post the settings here? Or in what order should I do?

I'll post those settings anyway

Okay so what should we change to increase stability?


Thanks man!

Re: Need help getting UD3R+E8400 to 4.0!

The settings look good. I just wanted to make sure we were on the same page. Proceed to test those setting for stability at 4 GHz. Is it stable?

[Th3guardian]

Re: Need help getting UD3R+E8400 to 4.0!

Okay man, testing them now!

okay edit!:

I ran Vantage again and guess what I receieved 500 more points!! Success man. :) Maybe we could even go for 450 fsb?

Now I'm guessing I should do some intel burn test to test stability even more.

Anything else I should do Outer?


Thanks for all your help!

[Outer Marker]

Re: Need help getting UD3R+E8400 to 4.0!

Glad to see we're stable so far. Yes, I would do some Intel Burn testing, and monitor your temperatures during the test as well. What do your temperatures look like? Let me know and we can evaluate what the next step should be. Personally, if you're happy at 4 GHz for long-term running of your system, we should look at tweaking memory timing to reduce latency and improve overall system response. Tight memory timings are desirable over massive memory overclocks.

[Th3guardian]

Re: Need help getting UD3R+E8400 to 4.0!

Yeah man, i'm glad too! As for the temperature, it is pretty okay, mostly it sits at 61C degrees@load (peak has been 63). Otherwise yeah, I would like to have 4GHz running for long-term. So I really wanna tweak those timings with you! (rofl that sounded weird) So what should we do?

Thanks!

-th3guardian

edit: okay I ran orthos for 2 hours@priority 9, 0 errors 0 warnings!

[Outer Marker]

Re: Need help getting UD3R+E8400 to 4.0!

Still stable?

[Th3guardian]

Re: Need help getting UD3R+E8400 to 4.0!

Yeah man, it's stable, nothing has happened so far! Last thing I ran was Orthos for 2 hours. I could probably do one more test, Intel Burn Test for example. Would that be enough?

Anyways what would be the next steps? If we are there so far?

Thanks!
