Don't you want to MANTA MANTA. (Getting started on manta. Lots of pics)

Tony - thanks for the driver strenght / slew infos. Looks like playing with them is advance form of finetuning the performance to max. OC. I never did it, but I want to try :D So, to determine the proper strenght / slew one need to measure the impendace of the data wires + know the ram PCB impedance + know what is best for the chips used on the rams?

Or experimenting near the max. overclock to determine with is best is the only one way?
Including the different settings for different memory banks, because of different lenght of the wires from it to the NB???
IIRC I heard that for example for DFI LP B mobo and nF2 in general, the empty slots should be run at 1/10 (strenght/slew) - interesting anyway :p:
I really wish there is a win-based drive strenght/slew tool to play with - for start, I would love to know what my DFI mobo set there using the auto values :p:

What these stranght / slew are even meaning, technicaly speaking for what exactly the bus/memory controler does to the rams anyway? It is something that determine for the chipset how fast the data pulse rise/end? Or?
Please explain, I just quessing what it is.
Thanks.


chew* - so, higher capacity modules require higher (sharper, because there is more load/capacitance?) strenght/slew timings? Hmmm, hmmm. This might explain why - since almost everyone is just using the auto settings - are the nF2 reported as notably worser clocker using 2x512 instead of 2x256... :rolleyes:
Could it be it? :confused:


Revv23 - show us what you can do! OC the hell out of it :D A little voltage bumb sure did not hurt... :shoot:

Well depends on the type of modules. For instance tccd has always liked weak drive.......however smaller modules require you to run an even weaker drive. An example of something liking a strong drive is Bh-5. You would run a tad weaker drive with 2 x 256 bh-5 versus 2 x 512.

For instance my 256 tccd tends to like's 0/2. Another person has had good luck with 2 x 512 tccd at 0/3.
My bh-5 2 x 256 tends to like 3/6. My guess would be 2 x 512mb bh5 would prefer 3/7 or 4/7.

My 2 gig modules aren't to picky but infineon really isnt't that picky anyway. For both sets of OCZ (ddr 400 and ddr 500) i have they run fine with 6/6.

Well, thanks for the suggestions :p:
I try them first in my DFI LP B mobo, tough :D I'm affraid that the auto values insert just suboptimal values there, so the mobo "works well" on auto with either TCCD or BH-5/6 rams. Is my assumption about right?
I mean - every company have to produce board that will perform at least well with either TCCD or BH-5/6 modules, so they set the auto values somewhere at 2/4 - witch produce average results for both types and therefore it is up to the user to choose the best values for his/her case :p:
Anyway, on nF2 is recommended to drive the empty banks at 1/10 - what it recommended for ATI Xpress 200? :stick:

And are these values (drive strenght and slew) possible to setup with the ATI tool witch come with the drivers? :confused:

The auto values 6/6 are fine for SPD detection which is ddr 400 3-4-4-8 with tccd............This is in not a default setting that will get you stable at ddr 600 2.5-4-4-8 though.............Using these settings in a DFI will probably be useless................as the bios is most likely different and the board layout is way different then manta reference........

I'm aware that theboard layouts are extremly different, however the main principe of things - TCCD need weak strenght/slew while BH-5/6 need notably higher one and especially for 2x512 configs should remain true.
6/6 default, huh? Well, good to know. The same is true for Grouper, right?

/me just wonder what is the default value on the DFI LP B with Hellfire rev.3 bios :p:

And unless I miss something - don't you forget to tell me, if the ATI system thing will allow me tweak the strenght/slew on the fly in win, or do I must go to the reboots for this?
IIRC you tell me, taht the ATI system tool allow every changes that one could do in the bios, but I still better askin twice to get clear reply - sorry about that :p:

Any new reports on this board?

white boards... :slobber:

er, 3200 chipsets are out now... 1600 series is old news.

This board is 3200.

bah, I read the posted date wrong, my bad.

super thread revival, i want one now :D

Then buy the Sapphire RD580 card.. it's the nearest you will ever come...

Rolle2K... Are you able to run those 4 sticks of BH5 at 1T? What Mhz?

markr: My sticks are pretty :banana::banana::banana::banana:ed up. so i haven't run more than two sticks, the SPD-chips are about to die on all of them, due to high vdimm (even if its still low for BH-5)... and my bios chip died about one day after i got the board. so i have to get a new chip. My usual luck :(

Sorry to hear.

My board gets here Wed. if Newegg doesn't screw it up again.

All right board is up and running with BT's bios. All good so far with out even a windows re-install. Just plugged it in and booted up. Only problem so far is temp monitoring. ATI System Manager reads CPU at -1c and ATItool reads my vid card at 0c. Anybody know what monitoring chip the manta uses? Is it the LM90 like the Gruper?

Try speedfan with /NOSMBSCAN added in the shortcut target :) (otherwise your machine will hang)

This is all covered in this thread ;)

Good luck!

Thanks Marlowe, but it doesn't seem to work with the latest AMI build bios that Tony was able to give us. All fields are blank. It has something to do with the bios I am sure as even the monitors in the bios itself are way off. If you are using this bios and it works for you please report so, maybe I need to reflash. Thanks.

Yeah I run the AMI bios too, and SpeedFan detects everything here. Some weird values, but they are there :p: We need ASM with support for this bios! :)
