3.99G usuable out of 6G?

What's the best that chip will do?

The ram is still the problem. If you look, it's only running at 598.5MHz Compare that to the settings above. It doesn't seem right. Plus it's only running at an 8 Mem multi when it should be running at a 10 with 1333MHz speed.

 

[MJinZ]

Should look like that.

Did you go to the EVGA forums and read about overclocking?

First off, you should check for stock capability.

That means no overclocking of your CPU and seeing if you can get 1600 memory, 1800 memory etc. Anything above 1333 will require a bump in VTT voltage.

1.65V V-Dimm.

I have a ga-ex58-ud3r in my wife's rig. Used some ocz ram and I'd get the same error. I'd switch slots and reboot and it would work again. Reboot a couple more times and it went back to xxxGb usable. Tried more voltage, loose timings, even clocked it to 1066mhz and it was 1600mhz ram. Nothing worked i'd still get the error. Finally ran memtest and my ram errored out fast. Got me some corsair dominator installed it and I've never had the error again. I think you've got some faulty hardware. I know how you feel cause I wanted to pull my hair out.

Found the culprit!

It's the 'Turbo Performance' feature under 'Frequency Control'

Yipee!

Lets just hope this Elpida hyper IC kit doesn't flop like they are suppose to..

It's not a memory issue your strap is wrong.
Nice thing about EVGA BIOS is it shows what your result is when you change it. Since you're not running 133 BCLK you must adjust your ratio. I prefer to be higher than lower but you MUST check to make sure you're not too high and getting ram errors!!!

Honestly with a D0 you SHOULD try 201x21. Good ones can do this with 1.3VCORE (VDROOP OFF), 1.3-1.350 UNCORE, +75mV VTT. UNCORE around 3600MHz.

If your ram is good it should do 7-7-7-16-59-1T at 1610MHz using the above. In Everest that's good for sub 40nS latency (12GB) and 24GB/S copy speed!

I did a bios reboot session again and when I turn on Turbo Performance, even with the strap at 1333, it will run 2:8 no matter what. When I turn Turbo Performance off/disabled, the correct input of 2:10 will work.

Currently my CPU VTT is a little high; at 1.32V, but I have lowered my Vcore to 1.20.

The VID on this chip is 1.44

I am running the RAM at 748/1506 and it just passed over 100% of 2x 2047 instances of memtest HCI @ 10.10.10.27 - not to great but JEDEC says I can run the voltage at 1.5v although I am at 1.59-1.60v

Uncore is at 3Ghz (20x)

 

[Rubycon]

With 6G those timings are horrible. Junk memory like Geil can do better. Try 8-8-8-24-59-1T MINIMUM. Remember VDIMM should be around 1.64V for this. That uncore voltage is not high at all. Vcore can be much higher as well. Just remember at 4-4.2GHz and 1.4V you will NEED good cooling - no stock cooler will handle it. Unless you like to grill salmon on your mobo. MMMMM grilled salmon! (stock GTX480 cooler with Furmark could do it har har!)

I understand those timings suck. It's just those Elpida hyper IC chips I'm worried about. They have over a 50% fail rate from what I've been reading. Even with settings well below advertised. As of right now, I just don't want to push them seeing as I've just reached a confidence in the machine I've spent so much time with just to ....run. Eventually, with time, i'll start to push this machine. I intend to only do mild overclocking. Maybe 3.4 or 3.6Ghz

still want your GTX 480 setup

hehehehe

 

[Rubycon]

With 480 SLI and overclocked GPUs you will be bottlenecked significantly with your cpu speed. 12 cores at 4.2GHz can keep up and turning up tessellation to the max at 2560x1600 helps too. 😉

You may want to get better RAM modules! A chain is only as strong as the weakest link...

I'm sure if waiting for a dual Fermi based board is the ticket for a faster Fastra or just to put six 480s in there right now! 😱

With 295s:

 

[BTRY B 529th FA BN]

LOL is that thing even active?

I see 7 cards...

Running those timings you suggested and at 1.64v drooping to 1.62. 88% by 1024 x4 instances. Seems good so far. I'm gonna run Cinebench, and a little LinX before I go any further..

 

[Rubycon]

It's a work in progress.

http://fastra.ua.ac.be/en/index.html

Waiting on four Thermaltake 2kW 230V PSUs at the moment. I call them DNF because I'll believe it when I see them. Even the SR-2 orders seem to take forever. Then again I figured it would be June at the earliest before the 480s came and I got the first batch in late April. 😱

 

[BTRY B 529th FA BN]

You are building a SR-2 machine with what cards?

I'm just needing one GTX 480 for a Adobe PP CS5 machine. I ordered a GTX 285 from a phantom eBayer. I submitted the payment on the 23, was posted on the 24th, I have since sent emails to the eBay and personal email account to this seller and haven't gotten one response.. So I guess I'll use the GTX 480 MPE "hack" until they officially support it.

So, that's 4 2k watt PSUs, DNF? ... o you are building 2 SR-2 machines, right?

EDIT: I think I was getting motion sickness watching that guy in the video..

 

[Rubycon]

I have EVGA OC edition 480s now. 5970s too but those are finding another use. (dust collectors!)

Problem is heat. The 480s are getting hot when stacked together. They really need to be water cooled and that I cannot do. Refrigeration (phase) may be allowed - waiting for decision on that.

I get two of everything procured so if I ask for four cards I'll get eight. The SR-2 is allocated right now and finding two is hard they said. The PSU even worse. Hence DNF (Duke Nukem Forever).

 

[BTRY B 529th FA BN]

Why are those 5970s sitting? What has made you do that? Is it something that is better about those 480s?

I'd really like to see a re-iteration of those 480s that generate less heat and use a little less power..

Because the 5970s are microstuttering pieces of crap?

Have not even bothered trying 10.5 CATS.

Even a single 480 was much better by far. Adding another just makes things that much faster. Rarely does a simple addition to a system make me smile like that. (well with computers)

Sure they run hot and make noise but so do Ferrari's. 😀

You could try the Spitfires when the VRM 480s come out.

Hmm :hmm: I've only just begun to experience dual GPU gaming. And so far it's been .... nice. I've been playing Avatar The Game :thumbsup: and a little bit of BF.BC2 :thumbsup:

I am going to get a 480 soon. Which do you recommend?

 

[Rubycon]

They are all pretty much the same. Get one with best warranty and support if that matters. My broker prefers EVGA so naturally that's what I wound up with. I'm glad they are not putting cartoons on the boards like they used to!

 

[BTRY B 529th FA BN]

A temporary fix for your space heaters!

 

[Rubycon]

We have plenty of cooling, temperature never budges. Matter of fact most of the time it's too cold!

<---looks at temp of Gulftown at 4.4GHz - yep idling at 15C. 😀
