E8500/HD5830 OCCT Problems?

Re: E8500/HD5830 OCCT Problems?

Glad to hear that your new e8500 o/c has been so "easy".
AnnandTech and several forum members have successfully overclocked their e8500 systems to 4.50GHz.
Your Mushkin memory should be able to run at 1100MHz with 5-5-5-15 timings with 2.02 volts.
You might be able to run them at 1140 - 1200MHz, possibly with somewhat looser primary memory timings and with 2.08 - 2.12 volts.
My Mushkins are stable at 984MHz (2.00D) with 5-5-4-12 timings and tRFC = 50.

Lsdme's suggestions are in his "How to setup CPU/MCH GTL Ref Voltages" thread where you:

1. Temporarily set CPU Termination (VTT) = 1.20
2. Make desired adjustments to either or both of these Reference settings (MCH Ref and/or CPU Ref).
3. Set VTT back to the desired setting

The following comment in your posted bios setting will make it perfectly clear which settings were used and applied:
MCH Reference ----------- 0.7600V ------- : [0.???] 0.### set @ VTT = 1.20
Where 0.??? is the adjusted value displayed after resetting VTT and 0.### is the new setting that you selected while VTT = 1.20 was temporarily set.

Happy tweaking!

Re: E8500/HD5830 OCCT Problems?

Ok, I bit at the "easy" overclock! The attached settings are stable all I changed from the prior settings was I set the reference voltages manually based on Lsdmeasap's instructions. IBT ran 10 passes 37 seconds faster with the actual reference method - probably W7 was doing something in the background the first time. Now for the problem at hand, as soon as I increase the FSB beyond 422 to 435 IBT fails miserably on the second pass. I then increased the Vcore to 1.35625V and IBT fails on the third pass. I increased the Vtt to 1.26V and IBT fails on the second pass. Make it easy on me to get to FSB ~450, do I have to give it a lot more Vcore and/or do I have to play with the reference voltage(s)? Seems like you guys hinted that the reference voltages may come into play above 4GHz and have to be decreased one notch versus just the opposite for the Q9550 setup. Still a slow learner!

Re: E8500/HD5830 OCCT Problems?

450 FSB put all your ref's back in auto until you get there, then you can tinker with them if needed.

2.40B and tRD of 8 at that FSB may be part of the problem, can you use 2.00D or 2.66D? If not try tRD 9 w/ 2.40B

Other than that, yes your voltages look a bit low, very low to me actually. I'd suggest you look at 1.36-1.42 Vcore and 1.28-1.34 Vtt for 450 FSB

[Ken429]

Re: E8500/HD5830 OCCT Problems?

Only sadness. I am trying to run at FSB 435 with a tRD of 9, as suggested. It seems like the more Vcore it get the worse it acts. I tried 1.38V Vcore, Vtt of 1.28V and it failed IBT on the second or third pass. I upped the Vcore to 1.38750V and upped the Vtt to 1.30V and it failed IBT on the first pass - wrong answer. The Mushkin Memory runs at FSB 450+ with a tRD of 8 on the Q9550 system? But this thing has sure hit some kind of a wall at FSB ~430. What words of wisdom do you have to try the 2.00D strap? Every time I attempt I end up with a system that won't even boot but if you think that is the issue what do I have to change in the settings in Post #17 to make it 2.00D friendly? I'm living up to the "Slow Learner" name tag!!

[profJim]

Re: E8500/HD5830 OCCT Problems?

Try the following settings first:
tRRD -------------------- 4 ------------- : [4] <-- set to AUTO for now
tWTR -------------------- 4 ------------ : [5] <-- set to AUTO for now
tWR --------------------- 8 -------------: [6] <-- set to AUTO for now
tRFC ------------------- 68 ------------ : [60] <-- set to AUTO for now
tRTP -------------------- 4 ------------ : [6] <-- set to AUTO for now
Driving Strength Profile --------------- : [Auto] <-- set to 1066 for both memory channels

Try these settings next:
DRAM Voltage ------------ 1.800V ------- : [2.040V] <-- 2.00 - 2.02 might help, possibly 2.06 - 2.12
MCH/DRAM Ref ------------ 0.900V ------- : [1.020V] <-- set to AUTO for now
DRAM Termination -------- 0.900V ------- : [1.020V] <-- set to AUTO for now

Other thoughts:
MCH Core that is too high or too low can cause boot or instability problems, 1.26 might help.
It looks like you lowered MCH Ref 1 step (with VTT = 1.20). Try lowering MCH Core one or two steps with VTT = 1.20 and restore your desired VTT setting.
CPU Vcore might need to be set to 1.3625 - 1.3750 or a bit higher.
VTT (CPU Termination) can safely be increased where it is only 0.04 - 0.05 volts lower than CPU Vcore.

When you post your new bios settings and results, please include the screen-shot in step #4 from this post that includes Memset, Cpu-z, ET6, and CoreTemp.

tRD = 8 and 2.40B (1102MHz)at 459MHz with 2.02 volts and 5-5-5-15 timings was the best my system could do.
With your cpu, you might be able to do a bit better before you need to switch to one of the 2.00 memory multipliers.

Another option is to lower your CPU Clock Ratio to 9.0 and use a higher FSB.

Slow learner? Nah.
Half-fast learner? Maybe.

[Lsdmeasap]

Re: E8500/HD5830 OCCT Problems?

If none of the above help, try all our suggestions again, this time using .68-.74 MCH Ref, with final Vtt value of 1.28-1.34

You may need more Vcore, 1.38 is generally only about 1.35 give or take a bit under load, so you may just need more than you are trying

[Ken429]

Re: E8500/HD5830 OCCT Problems?

Well, you were right on the 2.40B, although I don't quite understand why it runs at 1080 on the Q9550 and won't go over 1030 on the E8500 with exactly the same memory settings. I switched the memory strap to 2.00D and set the tRD to 9, the Vcore to 1.36875V and the Vtt to 1.28V and we have a success. It runs IBT for 10 passes successfully at FSB 448 or 4.25GHz. I have not run an extended Prime95 test but it looks promising. The core temperatures maxed out at 56C. Is that good? Go for more? Could the 2.40B problem be heat since it will run IBT for 5 passes ok first thing in the morning and then it all goes down hill.

[Lsdmeasap]

Re: E8500/HD5830 OCCT Problems?

Looking good! Temps are fine, you have room if you want

Not sure what would cause that in regards to the B Strap, I could see how it might be possible the other way around, I mean if it worked with the 8500 but not the 9550.

It must just be some Vtt or MCH Ref difference you need to find still

[Ken429]

Re: E8500/HD5830 OCCT Problems?

First the good news. Based on the settings below the system is relatively stable at FSB 448 with the 2.00D strap. I had to give it more Vcore to make Prime95 happy but then I don't think that was a surprise to you guys.

I then tried to go back to the 2.40B strap (tRD = 8) with the stable voltages for the 2.00D strap and it all unravelled again! IBT v2.5 ran the 10 passes using the 2.40B strap in 354.95 seconds versus 409.12 seconds using the 2.00D strap - that was encouraging but the temps reached 59C on both cores. OCCT would not run for more that a few minutes minutes no matter what I tried. I played with the Vcore up to 1.40+, tried increasing the Vtt to 1.30V (it don't like more that 1.28V!), changed the memory settings to AUTO per ProfJim's suggestion, tried tRD =9 and various combinations of the above which I can document, if needed, but no matter what I changed OCCT still came back with the core error. Since IBT generated 59C on both cores using the 2.40B strap I am reluctant to go to a Vcore much over 1.40V. Is that the issue? When the Vcore is set at 1.39375V, CPUz reports 1.36V when the system is idle and 1.328V under load. So with the faster memory timing does it want more voltage? I so, I guess I'm at the limit since I really don't want to go over the arbitrary 60C that I set.

Re: E8500/HD5830 OCCT Problems?

59C is nothing for IBT, actually fairly cool really.

Are you using LLC, it doesn't sound like it, maybe you should. 1.32 under load is the issue I would imagine, try LLC enabled or more Vcore so you get 1.34 or so under load.

LLC enabled will allow a lower Vcore set in the BIOS and end up at a higher Vcore than 1.32 under load. For example, if you set 1.385 in the BIOS with LLC enabled, you may get 1.365 in windows at idle, and then only a drop to 1.35 or so under load.

I think the issue is your large Vdroop, several ways to compensate for this, but you need to choose one it sounds like as 1.32 may be what is killing it under load, it's definitely not temps of 59C

You may need to lower MCH ref, this might allow higher Vtt and or help stabilize things. See my signature for how to set if you are not sure, this is a setting you just don't "Set" by plugging in a value.

Once you read how it works, try .68-.74 MCH ref with 1.28-1.33 Vtt

Re: E8500/HD5830 OCCT Problems?

Your IBT temperatures are excellent at 59 (C).
Suggestion: Run IBT tests using the maximum amount of memory for your system.

Follow Lsdme's recommendations where you:
1) increase cpu vcore
2) lower MCH Core 1 step to 0.740 with VTT @ 1.20 volts, then restore VTT to the desired value
3) as Lsdme said, you might need to try somewhat lower MCH Core settings
4) don't be afraid to increase VTT, but keep this setting at least 0.05 volts lower than cpu vcore

Most successful 4.00GHz or higher e8400/e8500 setups have cpu vcore in the 1.40 - 1.45 volt range when LLC is disabled.
Don't be afraid to run with LLC enabled where cpu vcore can be set lower.

In your other threads, I recommended leaving MCH Core = AUTO because you were running at lower speeds.
Don't worry about using the B-strap. You'll have noticeably better performance if your FSB is in the 480 - 500MHz range by using the 2.00D memory multiplier and a lower cpu multiplier.

Once you've reached your final overclock, you can tighten your memory timings.

Re: E8500/HD5830 OCCT Problems?

I got myself going in two directions! The system "seemed" stable in the settings I posted most recently - 4.25GHz using the 2.00D strap.

When I went to the 2.40B strap bad things happened. I followed the instructions to turn on LLC, lower the MCH Reference Voltage to .072, raise the Vtt to 1.30V and set the Vcore to 1.38750V and I lowered the DRAM Voltage to 2.02V for good measure (one step at a time!). Those changes made OCCT happy. It now runs to a normal 60 minute completion. I tried a Vcore of 1.38125V and OCCT failed immediately so I suspect Prime95 will want a little more that the 1.38750V?! It now looks like with a Vcore set at 1.38750V CPUz reports an idle voltage of 1.36V and under load OCCT logs 1.345V.

Should I make the above changes to the 2.00D "stable" settings? If I increase the 2.00D FSB beyond the 448 I would run into the same issue I hit with the 2.40B strap?

And to think I was ok with 4.0GHz.

Keep in mind that you can save up to 8 different bios profiles.
You can LOAD or SAVE bios profiles from the main bios screen, it's all in the mobo user manual.
You can't delete a saved bios profile, but you can replace the unneeded saved profile with a different profile and you can rename any saved bios profile name.
Be sure to save and print a hard copy of each of your bios settings, both good and bad.

A one hour OCCT or Prime95 test is not nearly long enough to ensure that your system is stable.
Sometimes errors won't show up for anywhere from 3 - 12 hours, or possibly longer.
When you run either of these tests, let us know how long the test ran and which specific test was run.
With Prime95 note the elapsed time of the error and FFT size that failed, or include the Prime95 window in your screen-shot along with the other standard windows.

Try raising CPU Vcore one or two steps higher. If needed, raise VTT gradually up to the point where VTT is up to 0.04 - 0.05 volts lower than the CPU Vcore manual setting in your bios. With more VTT, a borderline stable system will often run stability tests for a longer time before the test fails or it might let your system run error free for 12 - 24 hours or longer.

448 x 2.40B = 1075MHz. Your memory should be able to run at this speed with 2.02 volts and 5-5-5-15/18 primary memory timings.
At 4.25GHz, you might need to set MCH Core one or two steps higher when using the 2.40 memory multiplier.
If MCH Core is set too high, you will probably have boot loop problems.

4.2 - 4.5GHz is often doable, but this usually requires a lot more effort.
4.00GHz is a good sweet spot, but don't be afraid to go for the gusto.

Re: E8500/HD5830 OCCT Problems?

I think you are right, it ain't worth trying to get this thing to run at 4.25GHz with the 2.40B strap!! Seems like I get it to run OCCT for 60 minutes and then Prime95 ends quickly with an error. I change a few settings and it gets better or worse but still ends quickly with an error. Then when I go back to the settings that let OCCT run "ok" and OCCT fails immediately. Just curious, does messing around with the BIOS settings eventually screw something up other than the settings being tweaked? The settngs that let OCCT run "sometimes" are Vcore 1.38750V, Vtt 1.30V, MCH Reference .072V, tRD=8, LLC Enabled.

Anyway, I am back to the "stable 4.0 GHz" at FSB 422, 2.40B memory strap, 1.34375V Vcore, 1.312V CPUz at idle, 1.28V CPUz under load, 1.24V Vtt, LLC Disabled, tRD=8. Do these voltages look reasonable. The reason I question this is how much more voltage it requires to try to get it to run at 4.25GHz. Am I on the ragged edge of stable?

Second question again from previous post, I am "Stable at 4.25 GHz" with the 2.00D strap with a Vcore of 1.39375V, 1.36V CPUz at idle, 1.328V under load, 1.28V Vtt, LLC Disabled, tRD=9. Same questions as above AND do I need to tweak the MCH Reference Voltage to get to a higher Vtt?

Re: E8500/HD5830 OCCT Problems?

Some memory just wont work with 400+ FSB using 2.40B, nothing you can do except try different memory.

No need really to worry about it, D should be used anyway when running 400+ FSB, see my quick testing on this here
