DFI looks to have a winner here.

[Bourch]

yeah RW Bypass 16x is faster... interesting about 32bit granularity

Will try both settings.
Have someone had any stability problem with them?

[berserk]

Any news of the socket 939 DFI board?

[Klisp]

What are good optimal timmings for this board to really perform? 2-2-2-5-10-16 ?
(I'm trying to get to 30k on 3Dmark2001) Is it necessary to run 1T also ?

[ugp]

@ TinTin:
It seems to look like you have the same version of the 3200+ as me...what is the highest overclock you have gotten on it. I can't get anything over 2.337. I want to get 2.4 or more. I have a strong feeling it is my memory that is the problem though. Please help me out here.

[Bourch]

In my opinion 1T is a must. You can try 2T but will need much more mhz to obtain the same bandwidth.
In one of the first pages of this thread bigtoe did said he was running 2-2-2-0
Altough 0 supposed to be the same as 5 the last one was giving hims some stability issues.

After several testings this weekend on the 250-270 FSB range I couldn't get my system PRIME stable with more than 250FSB (tried 1.7vcore and till 2.9vdimm). It ran SuperPI, 3dmark without crashes and while running prime the system was stable (win didn't crash) but prime always failed.
I think the problem is with the mem. Maybe 2 x Double sided 512 ADATA PC4000 is too much for the memory controller.
Now I'm back to 250 with:
2.5-4-3-0 2.7V (2.7 was the minimum stable Vcore)
R/W Queue Bypass 16x
32 Byte Granularity 4 bursts
Newcasttle 2200@2500 1.55V (if 100% stable I'll try less Volts)

[eva2000]

IIRC, Tony/Bigtoe says for 512MB sticks increase drive strength to 2 ?

[Tony]

Thought I would give you guys a helping hand reaching ddr600 with the 3200 Plat rev2...this is just a good place to tweak from and should be stable if your dimms are pretty good clockers.





hope that helps you guys clock that little bit higher than you may have already acheived.Remember this is 1 dimm only with 2 dimms 270ish is about the max.

[p4z1f1st]

hmm.....thanks bigtoe

i'll try them on my 3700EBs (2x512MB )

so, how i meantion that, lowering bypass max, R/W Queue Bypass, and raising DRAM Drive Strength brings more oc-playground, right?

but, what is the DQS Skew Control?

but ok, i'll set my settings like yours and will see

[mad mikee]

Gee I guess I have another project for the evening

You back home yet?

I don't get it...
Put my RAM to 150, LDT to 2x multi to 6x, Vcore to 1.55V, Vdimm to 3.3V, chipset voltage to 1.8V.
Everything else was at auto.

Then i booted at 6x200 and increased HTT w/ ClockGen, brought it up to 270MHZ and tryed Spi 1M, no problem.

Then i set 271 and then 272 and it freezes.

I thought it must be ClockGen so went into bios, set HTT to 300 and it posted!
But then it said "detecting array" and rebooted.
So i went down to 290, same thing, then to 280, same thing but no reboot, had to reset Cmos.

Is my board maxing out at 271???

I had 2x256 sticks of HyperX pc3200 in slot 1 and 3.

Try using only one stick in slot 1.
What are your timings @?

I have the same problem, its the bios.

With the original bios i could boot in windows with 305MHz HTT with AUTO.

Now with 9/12 and 9/14 I cannot boot into windows with 275MHz > HTT (detecting array > reboot)

We need Oskar Wu over here.

[Ubermann]

Mine clocks better with chipset at 1.6 then anything higher.

[Bourch]

I'm pretty confused on that setting. I think 4 should be the most agressive 1 the more relaxed. No idea about AUTO. I'll try with 2 but is it 2 for 512 and ALSO for 2x512 ???
I think this would be the case of gamers that enjoy benching & OC ing

[Zeus]

Running 2-2-2-5 with 3.3V but mem never came above 215MHz or so, shouldn't be a prob.
Mem does 260 easy with 3.3V

Man, that's a slam in the face, expected at least 300.
Why is it whining about an array, i don't even have an array!

The original bios sux.

I want more HTT! C'mon bios doctors!

From Oskar_Wu

There are a lot of chances for bios code to access and write the cmos space ... No body knows what will happened to these cmos space when we are doing serious overclocking ... Once the system is not very stable but still try to write the cmos space data , the cmos data may be lost and cause the cmos checksum error ... Once the cmos checksum error , the bios code have to reset all setting to default in order to prevent a wrong cmos data cause the system never able to boot up again ...

Currently the HTT frequency is programmed after the RAID bios rom finish initializing ... The RAID bios rom will always try to initialize and see if there is raid setting in bios ... If there is RAID setting in bios , you will see the RAID bios screen ... If not , the system bios will quickly clear the screen , most of the times you will not see it ... But if you see the system stop at the raid bios screen when you overclock , that means the HTT programming sequence hang up and not able to clear the screen ... the system will reset it after a few seconds ... after three times of fail , there will be a prompt screen " Press F1 " ....

Guyz, I really appologize if this is off-topic a bit...

But my DFI board will be here this week, and I can't seem to find any PC-3700 EB ram !!! I'm starting to panic !!

Any suggestions or comments are appreciated...

I'd really like to get the most out of my 3200+ mobile A64, and this even if she feels like going to 2.7Ghz... just in case..

find some BH-5 or ocz EL pc3200 rev 2 platinum
also the ocz pc3700 gold rev3 is good.

[Tony]

3500 and 3700EB has gone EOL unless we find IC's that clock as well as the C die we were using...if you can find it snap it up

We do have a new 3500part coming which handles cas2 quite well but does not clock as well as the 35 and 3700EB...it is quite nice though

If you are looking to run a gig on this board i would recomend the 3200Plat rev2 as this does clock well with 2 dimms, and exceptional with 1 but its not quite as fast as the EB with tight timings.

Would PC-3500 EB be as good or close to 3700 ? Please explain what I'm looking at if I want to get a 10x multiplier processor to 2.7 Ghz (3200+ mobile A64). I'm affraid I'll be limited with the 3500 and I might not get quite as high on the FSB as I need to get for my cpu to fly...

I can get the 3500 EB, but i need to act fast. Thanks for your support.. I hope to contribute to what you are doing in here real soon !

[KingZer0]

So this is the place where all the happens!?
Nice 2 be a member of this great community

Can one of u guys please gimme a short overview about the Pros/Cons the
DFI posseses according to your experiences?

Maybe its time to sum a few things up cause this thread is overwhelming my brain a little and even my time

3500eb is fine get it now. You can always resell if you don't like it.

[SunTzu69]

Will the fact that I have to use a divider with PC-3500 EB kill me ? I see you guyz run 1:1 as much as possible... I thought it wasn't an issue with the A64 but it seems that it is to some extent. I plan to need top performance for gaming especially...

If you guyz say go for the 3500 EB now !! I will...
