RD600 first look and general questions

[cadaveca]

Have you played with FSB drivestrengths? 507 here.

[Eldonko]

Been testing various settings effects on max fsb most of the evening. Can do 500 w/ stock nb cooling but Im struggling to pass that. Maybe 10-20 in there with better cooling.

[cadaveca]

that chipset is mighty cool for that voltage, and stock cooling...

[Eldonko]

Maybe so, but its the stock cooler. 120mm over the ram likely helps alot though.

[cadaveca]

lol i figued, as that 26c PWM temp betrayed you. How about temps without the fan?BTW, what's up w/ that ram? No Mushkin?

[Eldonko]

Dunno what the temps without the fan would be, it is always there, it's my ram fan, nb cooling is just a bonus.

BTW, what's up w/ that ram? No Mushkin?

Heh heh, I got lotsa different mems.

A little bit ... by boosting the 4x fsb drivestrengths to 11h I have finally been able to boot and load windows with my qx6700 at 400 fsb (x9) but it's not stable enough to bench. This is with GTL refs at 166. But I'm not giving up yet!

lol. Nice mount for the TDX there too...lol.

GTL did not help me reach 500fsb. nmos/pmos did tho, so it was definately the board holding me back.

GTL i normally run @ default, or 72/72/72.

[Eldonko]

I tried a bunch of GTL values, didnt find it did much either. Got some more stuff I am going to test though, I know there is a little more room for max fsb. You guys find any mem settings helped fsb at all other than trfc?

[Aivas47a]

Not that I've noticed so far ... what's your experience been with trfc/fsb?

FWIW boosting ADDR/CMD Driving Strength and Clocking Driving Strength to 10 or higher seems to help stabilize tight ram timings.

Yes. I can scale much farther CAS4 than 5

I also run normal micron alpha timings for given CAS...which is very hard on some DIMMs, but works well for me. I really wish i never sold my 8888's!


So, 3-3-3-9-12-21-2-3-2-3-2-3-2-2-5
4-4-4-12-16-28-3-4-3-2-3-2-2-5
5-5-5-15-20-35-3-5-3-2-3-2-2-5

For 450mhz or lower. Otherwise, I find increasing TRC and TRFC to not really make a difference, but keep in mind that micron like it's timings on this board I find. don't forget addres/CMD and clocking drivestrengths!

was much easier to get 1200mhz rams 4-4-4-12 than 5-5-5-15.



What strikes me as odd is YOU asking. WTF?


oh, and if you use above settings poster's for strength, i think 2.0v vdimm is almost too much or DIMMs will sustain damage.

[dasa]

hmm so upping that puts more stress on the ram dose it
so running this 24\7 may not be so healthy?

[cadaveca]

you are at the edge for Micron. I've seen 12 and 2.4v kill a set

[Eldonko]

Not that I've noticed so far ... what's your experience been with trfc/fsb?

Well, I found loosening tRFC/tRD on my 965 boards allowed up to 10 more fsb than tighter settings; however, doesnt seem to be doing much w/ this board so that is why I asked.

What strikes me as odd is YOU asking. WTF?

Whats that supposed to mean, we cant compare settings and experiences here or what?

hmm so upping that puts more stress on the ram dose it so running this 24\7 may not be so healthy?

That's correct, it's best for your mem to use the lowest drive strength you can without losing stability.

[cadaveca]

just joking, man. That's kinda the whole point in posting in the first place...

[dasa]

ok thanks for the info
shame this stuff isnt as tough as bh-5 it could handle just about anything
guess ill play around with a lower 1t speed or higher 2t
but for now 500mhz 2t 2.3v strength 5 will do

[Eldonko]

Question. Do you find hci or dos memtest is able to find memory errors with this board? Im having some 3d issues that lead to bsod and minidump (which is usually mem) but stupid memtest finds nothing in several hours..

[cadaveca]

Yeah. I have found that 1T will be memtest stable, then need 0.5v to retain 3D stability. I have tried tweaking drive strengths to no avail. Sync can cause issues... as well...same deal.

Also found that chipset volt issues can be hidden by over-volting mems...this will lead to 4-5hour stability( for me, but that may be jsut the DIMMs i got), but then BSOD/dump. But i found that TDU will not load if this is the case...


Sync requires avg 0.15v chipset more than unlinked. FSB drive can help, but i have not found more than using .05 less, so cannot be bothered ATM.

[Eldonko]

Ok thanks that's good to hear. Ive been troubleshooting every piece of hardware in this system all weekend trying to figure wtf the 3d issues were coming from. Stupidly I ruled out the mem early when it passed a couple thousand % hci memtest; however now that i thi9nk about it a lil more the crashes seem very mem error-like so I am going to retest using 1 stick at a time. I guess 3d mark is the new memtest for this board huh.

[cadaveca]

even that is not quite enough. all other apps I have can run, and TDU will fail. I checked system resources while the game was loaded, too, and found nothing all thta amazing...it's strange to be sure, but...


verify chipset volts are enough. sync means lots of volts, unlinked means just a little less.

give a bit less vDIMM.

tighten timings. (trc is good for this)Still good? then chipset, most likely...1.8v voltage tho. this settingis very important, i find, when dealing with ram tweaking. corrupt bios if not enough is VERY possible.

[dasa]

ah bugger looks like i was to late ever since i lowered the settings i have been havening stability problems
back to stock settings now and getting a lot of instability and memtest isnt showing much other than the odd error in test 1
ram might be about stuffed

[cadaveca]

If stability is an issue, CMOS clearing shuold be standard practice BEFORE looking at components. Settings/BIOS can be easily corrupted by an unstable boot. This board is pretty resilient, but it's not bulletproof.

ive been havening trouble posting after clearing bios with the jumper or telling bios to load defaults
ive had to leave the pc turned of at psu for a few min then come back to it and then it will run again
it seems to go ok for a while running prime for a few hours passing memtest playing games ect. then i start running into severe instability again
i dont know yet i still have more testing to do but it is starting to look like something is not as good as it was

with some luck it may turn out that nothing is damaged time will tell i guess

I do not agree with this at all..my first board was far from resilient...one setting of 1:1 and the bios I guess corrupte and the board developed an unrecoverable C1E error

Second board developed issues after being 26hr prime 95 blend stable, 3Dmark stable, memtested....

adios and goodbye RD600..not looking back..I personally feel the board is awesome for options but just was not of good quality after having 2 with serious issues

[cadaveca]

LoL. But you gave up, and here I am, still tweaking away at my leisure, first board.

I've spent time with three of these boards, all behaved similar. With just the first board, I've spent far more time delving into the possibilities than you have, so to me, my greater experience means I have a better understanding of what's going on.


You couldn't even figure your problem out.
