I thought the dongle is just used for the two cards to communicate. How will the dongle help with bandwidth? Regardless of the dongle, the information still has to travel through the PCIX slots.
Anyways that doesn't matter as xfire is useless for me. I just want to know is it easier to clock the memory on the new board.

I would be more interested in if it can clock memory higher than the previous board and am working on that now.
There is no reason that two X1900's cant go dongle-less just like 2 X1800's.... other than ATi feels like having it that way. Just like there is NO reason the cards cant work in NF4 boards other than ATI coded thier drivers to forbid it. Enough with the BS.
And if the bandwidth is a bit too low for best results dongle-less... then just turn up the PCIe clock from 100Mhz to 150Mhz. Certainly a 50% increase in clock speed will fill in the gap.
Time for ATI to knock off the crap and pull the prohibitions out of the drivers.
You wanna sell me 2 X1900's.... then allow them to work in my NF4 SLI-DR, sure it wont be as fast as using the dongle, but Ill live. Eventually if the RD580 based boards get good enough, Ill consider switching. Im certainly open to that, but if the RD580 boards cant at least EQUAL the performance/feature abilities on the NF4, why the hell would I bother.
Taking two steps back to take one step forward is pretty dumb. How about one step forward and ANOTHER step forward instead?
Meantime on RD580 testing, time to see how far BH5 2x512 and 4x512 go, as well as TCCD and Ballistix goes. Get'er done.
I'd like to see UTT BH5 results. Vdimm options are still good right? If I can get 270 2-2-2-5 still with 3.6v I'll be happy :) Might even sell my DFI boards and pick this up if possible...
Chew, please drop the multi and max out the HTT.
Pics of the board and such might be nice too ;)
Thanks! :toast:
drop multi and max out Htt? I already ran 9x300x5x Ht mutli........ you want more than 1500 total Hyper transport speed? As far as pictures go I suggest you re read post # 1.
Vdimm options are still good yes.
As far as Bh-5 goes I only have 2x256 mb sticks........Same goes for Tccd. They are benching sticks and that is there sole intended purpose........Seeing as how real TCCD and BH-5 are no longer available or very rare I would think it is inconclusive.....2 gig dimm performance would be more realistic for most users. Of course since my bank account is dry atm I have no plans to purchase 4x512mb dimms just to test. If anyone want's to send me ram for testing i will do so....otherwise you'll have to live with what i have which is the following 2x256mb bh-5, 2x256mb TCCD F1 LA week 440, 2x256mb TCCD F1 LE week 437, 2x 256 crucuial ballistix pc 4400, 2x512 mb Corsair speed binned UCC pc 3200( i run at ddr 500 ) 2x1gig OCZ infineon 2-3-2-5 Pc 3200 and last but not least my personal favorite 2 gig OCZ plats EB PC 4000. I also have a bugdet set of 2x 512 supertalent pc 3200 that i can test for those who want to know if they can get away with using cheap ram on this board........
I think he is meaning 400htt x 3 or somethingQuote:

For all practical cases, x4 (800MHz mode) is the lowest you need to go...and that will be above 320htt. For anything lower, x5 (1GHz) should be okay but it does depend somewhat on the processor so results do vary a bit. But that is the ballpark.

Understandable since you don't have the stuff. However, I'd definitely disagree that just because TCCD and BH5 are hard to find now that it's less realistic, just look where you are ;). As for the UTT BH5, I believe the G.Skill GH still uses that and a lot of people are still using older Redline, OCZ VX, etc. Maybe somebody with 4x512 of that stuff can let you borrow some for a while and see how the Sapphire board works with it. Either way, keep up the good work! :toast:Quote:

Grayskull do you have any insight to why Sapphire went with the SB450 southbridge and not the ULI? Is it because of the close relationship with ATI or what?
I would guess as to the fact that they used the SB as there is nothing wrong with it in real world applications........
Isn't the SB460 pin-compatible with the 450? That would be my guess as to the reason....Quote:

What is this master card and dongle issue you guys are talking about?
Will a RD580 board work with just one nVidia card?
Yes it will. Pay no attention to the thread crapper. He's just ticked off that he can't run 2 ATI cards in an nvidia board but for some reason doesn't bash nvidia for the same thing....Quote:

Chew,
I got a question for you ...
I am new to Amd systems ... I actually just built my first Amd OC system with the specs below and I am currently geting a 1000 Mhz OC at stock volts with an Amd Stock 165 heatsink on a Ultra -d.
Now, I have another retail 165 UPMW with even a better batch number of 0069 [ I learned about the batch number issue reading one of your threads and if it the last four digits on the third line then it is indeed #0069 ] ... do you think an RD580 board will give me even a better OC on air than I am currently getting with the Ultra -d? 311 HTT, 9 multiplier, 3 LDT [ never tried any other ldt ]
The reason I bring up LDT is because from my reading, the RD580 will run at a 311 HTT with a 4 or 5 LDT but how much actual real program perfomance gains will that accumulate to, if any at all? I use 3d programs ... will a 165 [ 311 htt, 4 ldt ] render faster than a 165 [ 311 htt, 3 ldt ]
I am looking for a board to go along with this ' better batch ' 165 but I am not sure how much more this 1.8 Ghz can actually OC to
I'm honestly not sure if there are any gains atm as i havent tested but when i ran 4x Ht by 370 last night and was copying ,pasting, uploading, and posting the machine appeared to be running alot quicker. Ill have to do some further testing on that. As far as a higher OC I wouldn't go as far to say that but as a more stable platform i will say yes. Once its dialed in right from my experience its set it and forget it. No cold boot issues,warmboot issues, or any other issues.
Finally! :clap:Quote:

Also, let's say for arguements sake, 340HTT is the highest at 5xLDT, how much of a diff in performance is it at let's say 400HTT at 3XLDT?
I'm sure Chew* will answer all of these.. Great work man :toast:
Did this thread fall off the face of the Earth?
Hey chew great work on that thing, you are about a week ahead of me, crapload of memory timings on this thing makes for onr hell of a learning curve, i did some math and just playing with the 5 different drive strength areas alone gives 1560 different combinations.
so far ive gotten 315x10 with the 5x htt on my opty 146 with this thing, amazing!
Not trying to steal your thread chew, but heres mine, with pics of the board, i wont link it again:
