P8Z77 WS

[LtMatt]

8Pack can you help me please im having some problems with my motherboard. The problem im having is sometimes it will not boot. It makes a single beep but the display stays off and the vga light is on by my gpu. If i turn the machine on and off again it normally works fine. Its fully stable in games and stress testing. The Q codes when it gets stuck booting are usually 93, 95, 96 and 98. Usually its 93, but it does vary sometimes. A couple of times it has not booted and the motherboard has left out a long beep followed by 3 short beeps. I'm out of ideas.

THanks mate, appreciate the reply.

Well i decided to send the board back. I'm impatient and well, it shouldn't be this much hassle. I've ordered the same board but brand new this time instead of a refurb. Hopefully the new one works ok.

To answer your questions though, i was using offset voltage. PLL over volt was disabled. I tried experimenting with VCCIO all the way up to 1.2v, made no difference. I did not try at stock, i must admit. I will do that tomorrow morning, just to see if it still occurs before i return it.. Either way though i think im sending the board back as i got a decentish price on a brand new one. (£227) Lovely board, just this one issue with the boot. Had no trouble getting my 16gb of sammy green to 1T either copying your seconds and thirds all the way.

 

[LtMatt]

Test at stock man!!!

This is a must as one stick of memory etc could be the problem.

Phew, thats a relief. It does it at stock settings as well. (cpu 3.9ghz memory 1600mhz 11-11-11-28-2T)

Two boots were fine. Third boot pc beeped, no display monitor stayed off. VGA Led was on and Q code error 93 was displayed.

 

[LtMatt]

8Pack,

Got my new board, working perfectly so far.

I was wondering if you can help me tweak my thirds? I've not had much luck playing with them. Can you recommend some settings? I will attach a picture of my current seconds and stock thirds. Cheers.

Work on seconds first.

Refresh interval 7936 and TWCL 7 would be a nice boost.

Then try and dial down
tRRSR and tWWSR.

Cool thanks will try those out. Which one is TWCL?

EDIT

Google says its write cache latency, i see that one.

EDIT 2

Booted ok with both of those tweaks. Will run intel burn test for 20 runs and report back. Cheers.

 

[LtMatt]

Dude you could have bought a Gigabyte Z77X-UP7 for less then you paid for this board.

What's the difference? I got this board as i wanted x16 x16 crossfire and i like and am familiar with Asus boards. I can also go tri fire at a later date if i decide to with x16 x8 x8.

tRRSR and tWWSR.

Passed interval 7936 and TWCL 7, 20 runs intel burn test stable. I can feel the system booting quicker, amazing. I want moar!!

How much should i reduce tRRSR and tWWSR by?

EDIT

I can't reduce them any further, 4 and 4 is as low as they go 8Pack. I can't select 3 and 3 in the bios, only higher numbers. .

8Pack is there anything else i can tweak or improve? tRRSR and tWWSR will not go any lower than 4 and 4.

 

[LtMatt]

No I would leave as you are now for stability.

Damn. I feel like there's room for more, im at such low voltage as well. Maybe i could try increase BCLK at tad i guess.

Thanks for the help.

 

[LtMatt]

Increase volts then man. That is always am option.

Will do.

So far got those timings stable at 102.1 BCLK with volts still at 1.575v and VCCIO at 1.100v. Get errors over 103 BCLK so am going to settle for 102.9, just need to get it stable.

 

[LtMatt]

8PACK what is CLK Period and is it worth me tweaking it? If so what would you recommend based on my specs, memory amount etc? Cheers pal.

 

[LtMatt]

8Pack ive made a new discovery. Dram refresh interval 7936 is not stable, unless i change the command rate from 1T to 2T, then 7936 is stable. If i use Auto on dram refresh interval then it auto picks 8320 and 1T is stable again. Which is the best option to choose? Should i try a different Dram refresh interval?

EDIT

Ignore 2T just isn't stable with 16gb. 1T is stable with 8gb. I'll have to live with 2T but im using the rest of the timings in the screenshots above + your recommendations.

 

[LtMatt]

Yeah fine. Just switch to 8gb when benching and almost stable should pass all but 11 Physics which hits RAM hard.

Cool. Can you tell me what DRAM CLK Period is and what setting i should use? I'm using CL9 at the moment, i read 5 is best but the pc wouldn't boot with that selected. From some quick testing 3, 7 and 9 are stable or appear to be.

 

[LtMatt]

8Pack i need your expert help. I admit defeat. I've got 8GB stable @1.65v with timings of 9-10-10-21-1T, seconds of 4-88-10-4-20-4-4-7 and thirds auto. VCCIO 1.1v VCCSA 0.925v, PLL 1.75v. Rock solid stable, passes all tests.

16GB on the other hand im having more trouble with. The problem is i can get it to pass intel burn test, but upon next restart or when i power off my pc its unstable again. So something is up. Can't seem to get 1T stable with 16GB at all, however im now having trouble tweaking secondary timings for 16gb. Can you give me some settings and voltages to try? I'm at my wits end trying different combinations. I've tried similar timings with 16gb but its not working, even with 1.7v and VCCIO 1.2v. I'm tried putting the TRFC down (296) for example with the timings above when using 16gb and it passed intel burn test. I then restarted, lowered it some more and tested again and it was unstable. Upon putting it back to the old settings, its now unstable at that. That's what's confusing me.

 

[LtMatt]

Try 9-12-12-21 1T first primary. TREFI auto, TRFC 156 and TWCL 8 put the thirds to auto appart from TRRSR 5. Let the memory do a full train so ideally do full bios reset and then input these settings.

Thanks, will try that.

However something weird has happened, it appears that after using Dram Read and write additional swizzle every thing appears to be stable, or almost stable. I just passed 10 runs on intel burn test and failed on the 11th run. I've added a touch more vcore and am testing again.

I don't understand why swizzle appears to have solved the problem, but it seems to have. I need to complete a full intel burn test, but i think a touch more vcore will get me there as although it failed the number fail was similar to the pass number.

I also copied some of your settings from this thread. The slew settings. No idea if this helps or not.

I've now disabled MRC Fast Boot as well. Previously i would disable it, get things stable restart and enable it. A day later or another restart or two later the system would be unstable again. Confusing as hell. Since i enabled read and write swizzle, its not done this, though its still early days and it could mess up again tomorrow or something.

Here's what im currently using (if this fails intel burn test i will try your timings above and start over) Will post back in a bit and let you know.

 

[LtMatt]

The fast boot disabled will force training on start up so this is a good idea.

Yes those slews are ideal for Sammy. Not used slews for as while as I don't touch Z77 these days unless I am needed to test very specific issues.

The Read and Write Swizzle Enabled often helps this stuff. It should only be disabled if going for RAW frequency and not at all bothered about stability.

Voltages VCCSA is too low Stock is 1.05 v For higher clocks and multi memory I suggest tuning from 1.1 v upwards.

Right, will increase that to 1.131v in the bios. Will go higher if required. I almost passed Intel Burn Test, failed on the 18th run so getting closer. So far after rebooting, no major stability issues, just not quite IBT stable yet. Still early days but i think the read and write swizzles have solved the problem. I noticed that my cpu vcore now needs to be a bit higher as well, maybe due to the tight timings on the seconds. Also bumped dram up to 1.675v to see if thats causing the fail towards the end of the test.

 

[LtMatt]

Do you play Intel burn test!!! Come on man!!! Thats stable enough for like 99.99% of everyday uses.

All these tighter timings will put stress on the CPU but I am sure no everyday application will give you the heat of IBT. This is probably why its falling over so late in the run.

Lol yeah i do use it a lot. Temps top out at around 83c with my h100i. IBT is time consuming for sure but it does normally produce consistent results, though since ive been tweaking my seconds its not been working so well.

I've got memtest on a usb stick, could use that. Any specific test?

Could re-download SuperPI. What do you suggest?

I'm just trying to get the best possible memory performance, speeds, read write and ensuring the pc is 100% stable so i can relax and play games, at 5ghz.

 

[LtMatt]

Yeah maybe man. Will try some other stuff . I will do one last run though, as i feel im close.

Its weird though, 1T was never stable, yet swizzle makes it stable and now you can see what ive done with all the timings. All copied from your tuning thread. Took the lowest timing for each secondary i could find in your tuning guide.

Cheers for the help. I will post back with an update, but its looking good so cheers.

 

[LtMatt]

I recon its fine I honestly do!!!

Your games etc are the best tests.

Ok this is Intel Burn Test 20 runs of very high stable.

Is it worth me tweaking the thirds?

TRWDR used to fail to post at any lower than 4, as did TRWSR. The only ones that were tweakable on 2T (before i discovered swizzle) were TRR(DD) and TRR(DR) and TWW(DD) and TWW(DR). The others are all as low as they can go. Not sure if this has changed now i have 1T stable and tight seconds with swizzle slews enabled.

Should i tweak DRAM CLK Period as well? Don't really understand this one and its not mentioned in your tuning guide.

EDIT

Here's my Aida speeds and latency. Memtweakit does not work for me, i guess because i have a P8Z77 WS board.

Not sure if those read/write speeds are good for 2133mhz on sandy or not.

 

[LtMatt]

Thirds are fine. Use the machine now. Aida scores are good for the RAM speed.

Cheers man, appreciate the help. I'll only return if tomorrow or the day after it becomes unstable again.
