Your Dram refresh interval seems to low i would say,theirs lots of things you could change on your memory side to get better performance,at those speeds you should be able to run tWCL 7.It looks to me that you have touched to many things in your memory tweaker to get a big efficiency score,im not trying to bag you but its not all about big efficiency score.Back off on the tweaker and slowly test as you drop things down

When you say too low... too low as in unstable it's way too tight, or too low as in i could tighten it a lot more?

This is for a 24/7 overclock, obviously why im doing 24 hours p95. These are all the default timings my RAM goes to when it's at 1333 mhz CL9, which are rather tight - my ram's XMP profile and what it defaults to when set to 2400mhz is a lot looser than those timngs, like double them. All of them are default 1333 timings except: twl=8 (i hear it should be same as tcl so w/e), trfc=100 (74 not boot), RWDRDD = 4 (3 no boot), RRSR=5 (4 no boot).

So i figured instead of going crazy on timings, i try to work around these default 1333 timings. But if you know any I could tighten with no problem, please, be specific.

This was a recent benchmark I did:

Is std for it 9000? 5200 is to tight
post #5094 of 6656
Standard was 9360 for it when it's set to 2400mhz. Unstable is unstable but I feel like I'm right on the edge of stability here, no?

I'm going to let this run of 1.76vdimm with turbo LLC go through. If it fails, I'll try reference interval from 5200 to maybe 6000 (back on 1.75v too).

Yeah if you bring it back up it should help you if not start off like this

Don't use XMP profile,just run 8-12-8-28 @ 2400Mhz tRFC 100-120 tWCL 7-8,leave everything else on auto,start off at about 1.65v dim and once that is stable then work your way down.Here is a pic of my Ln2 run and i can run these tertiary timings on air and these secondary timings too @ 8-12-8-28 2600 Mhz 32M stable ,always leave that Dram refresh interval at auto to start with,in this Ln2 run of mine its on auto.I think at 2400 Mhz it should be about 9300 i think
post #5096 of 6656
That 5200 refresh interval will be making your system unstable good luck anyway if there is anything you need to know if I can help I'll be happy too,you may find if you set it up ok you will be able to run your dims@2600 mhz
8-12-8-28 or 9-12-9-28.
There is somethings you could back off in your Tertiary's and secondary's to make it stable but i would start fresh
Oh and I have a gigabyte UD3H and i love it,awesome overclocking board for the price

Hi,
Was wondering if anyone in here could help me please?

I have the UD5H board but recently have been getting the code 04 on the LED. It used to sit on A0 which I believe is normal.

I am running off the onboard graphics at the moment so don't have any connected graphics cards only a PCI TV card.

The code doesn't seem to be in the manual.

Any ideas?

Don't use XMP profile,just run 8-12-8-28 @ 2400Mhz tRFC 100-120 tWCL 7-8,leave everything else on auto,start off at about 1.65v dim and once that is stable then work your way down.Here is a pic of my Ln2 run and i can run these tertiary timings on air and these secondary timings too @ 8-12-8-28 2600 Mhz 32M stable ,always leave that Dram refresh interval at auto to start with,in this Ln2 run of mine its on auto.I think at 2400 Mhz it should be about 9300 i think

I'm not using XMP, this ram has no XMP (well it does, but mine doesnt because I think mushkin custom made it for me during an RMA). The XMP of this ram though is 2000mhz 7-10-8-27 1.65v with very very loose secondaries and tertiaries. 2400mhz was just not prime95 stable on 8-11-8-28 or anything, and 2600mhz is extremely prime95 unstable at 9-13-9-33 so I didn't really try hard to get 2600 to work. I think to run 2600 24/7 I'd need to do something like 1.8, 1.85v, and as I understand, that's a bit too high for 24/7 voltage? I mean if max ram temps are 70*C then I'm staying very cool at 50*C as a max.

I actually did run on auto at first, though. I've been working on bringing it down but I've worked so many of the timings differently, like I changed the tRas from 27 to 28, so now all those previous tests arent really worthwhile and I got a lot of changed timings that I'm not sure which one is responsible for the instability.

Hopefully 1.76v turbo llc is enough of a boost up that it'll make this dram ref work but I've heard more than once now that my dram ref is way too tight. If this current run fails 30+ hours, I'll set dram ref to like 7360.

I thought you all might find this interesting, and in any case, I'd enjoy hearing feedback as you might also audit these conclusions based on your own expertise with this motherboard.

I'm an independent filmmaker who pushes technology to the furthest limits at all times, because I'm grinding through highly compressed full-HD footage while applying numerous layers of GPU-accelerated effects, onto multiple tracks and camera angles inside the Adobe Premiere Pro CS6 workflow. One of the critical ingredients to surviving in that context is disk access speed (complementing CPU power, which is an Ivy Bridge 3770K as indicated in my linked specs) -- and this is one area (in contrast to gaming, which is overrated for system demands) where a RAID 0 array of SSDs actually results in meaningful performance gains.

The dilemma from my UD5H, though, was: I wanted my RAID 0 SSD array (two PNY XLR8's adding up to half a gigabyte) to co-exist with my Vertex 3 SSD boot disk. We only get two Intel SATA-III ports from this motherboard, and those ports are the only ones (to my knowledge) that offer native TRIM, while the Marvell ports do not. Since junk collection (of the kind that supplements any modern SSD's own internal junk collection) is more critical on the boot drive, and almost useless on a mostly read-only drive, I didn't have the option to move my Vertex 3 SSD boot disk over to those Marvell SATA-III ports. In the meantime, I did try out the RAID 0 SSD array on those Marvell SATA-III ports, which are supposed to provide a theoretical headroom of 1.2 GB/s (i.e., 600 MB/s x 2), but I got a stunningly offensive, ridiculous, laughable 350 MB/s or so read rate -- from a RAID 0 SSD array! Those PNY XLR8's are rated at around 500 MB/s read speeds!

Bottom line, I felt that the optimal compromise was this: move the boot SSD onto the Intel SATA-II ports, hitting up against the bottleneck of 300 MB/s (whereas the drive normally performed at around 500 MB/s on the SATA-III port). Then, assign the RAID 0 array to the two native Intel SATA-III ports. No joke, in that configuration, using ATTO Benchmark, I got over 1.2 GB/s read speeds. That's a godsend for constantly pulling multiple HD video source files (many of them over 1 gigabyte in size) into any complex video editing workflow.

I haven't found conclusive proof -- and there's nothing in this entire, long thread about it -- but I suspect that the Marvell SATA-III controller is grabbing (for life) onto a singlular PCI-E x1 lane, leaving way less bandwidth than necessary to live up to even one single 600 MB/s SATA port spec, let alone the aggregate of several SATA-III ports. Does that sound right? And moreover, what stupidass moron would engineer things this way, calling a port SATA-III when it performs sub-SATA-II?

Looking forward to your counter-analysis!
